Description

VEHICLE VEHICLE, DOUBLE PEDAL DEVICE, PEDAL UNIT, ACTUATOR AND DRIVER'S STAFF FOR USE IN THE VEHICLE VEHICLE.

The present invention relates to a driving school vehicle, a double pedal device with hydraulic coupling, a pedal unit, actuators and a driving instructor stand for use in a driving school vehicle.

A relevant pedal set arrangement for driving school vehicles is described in WO85 / 03369. The known arrangement has a first pedal set with a brake pedal and a clutch pedal, which are located on the driver side of a vehicle and are actuated by the learner driver at the driving lesson, and a second pedal set again with a brake pedal and clutch pedal, which are located on the passenger side and from the driving instructor during the driving lesson. The brake pedal on the driving instructor side is coupled to the brake pedal on the driver side via a hydraulic device. Likewise, the clutch pedal on the passenger side is coupled to the clutch pedal on the driver side of the training vehicle via a hydraulic coupling device. If the driving instructor actuates the clutch pedal or the brake pedal, this actuation or deflection of the pedals is transmitted via the hydraulic devices to the corresponding pedals on the driver's side of the vehicle.

The driving instructor generally actuates his pedals when there is a dangerous or emergency situation, e.g. if the learner missed a necessary braking process, or in order to exemplify the appropriate pedal action to the learner by activating the teacher's pedals. Each of the known hydraulic coupling devices comprises a drive pressure cylinder with a piston rod, which is fastened to the respective pedal on the teacher's side, a driven pressure cylinder with a piston rod as the pressure cylinder device, which is connected to the associated pedal on the driver's side, and a fixed pressure line between the two pressure cylinders.

Since the force of the pedal actuation is transmitted directly via the respective piston rod to the liquid column in the hydraulic coupling system when a pedal is actuated on the teacher's side, the piston rod may bend or bend, which leads to jamming of the piston rod and the pressure piston attached to it in the associated pressure cylinder can lead, with the consequence of a functional impairment of the hydraulic pedal coupling. This often creeping malfunction can occur in an emergency, e.g. in the event of an emergency stop, which is to be triggered by the driving instructor, lead to an accident.

It is therefore the object of the present invention to provide a double pedal device for a driving school vehicle which reliably prevents malfunction due to the deflection of the piston rod of the hydraulic coupling device.

This object is achieved by the driving school vehicle according to claim 116 or claim 117 and in particular by the double pedal device according to claim 1 or claim 49, the pedal unit according to claim 27 or by the actuators according to claim 40 or claim 43 for use in the double pedal device.

Accordingly, the double pedal device according to the invention for a driving school vehicle has at least one driver's pedal, at least one passenger-side pedal and a hydraulic device that couples the driver-side pedal to the passenger-side pedal in such a way that when the passenger-side pedal is actuated, the driver-side pedal is also actuated, the hydraulic device at least one driver-side pressure cylinder device that is coupled to the driver-side pedal, at least one passenger-side pressure cylinder device, which is coupled to the passenger-side pedal and is symmetrical to an axis of symmetry, and has at least one pressure line which hydraulically connects the driver-side pressure cylinder device to the passenger-side pressure cylinder device, a slider, which is connected to the passenger-side pedal and the passenger-side pressure cylinder device Power transmission between the passenger-side pedal and the passenger-side pressure cylinder device is mechanically coupled, and a guide is provided on which the slider preferably the is articulated so that only one force or force components act on the pressure cylinder device in the direction of the axis of symmetry of the pressure cylinder device when the force is transmitted from the passenger-side pedal to the passenger-side pressure cylinder device.

The present invention has the decisive advantage that only horizontal forces, that is to say forces which act in the direction of the axis of symmetry of the pressure cylinder device, can act on the pressure cylinder device and thus avoid bending or kinking of the piston rod of the pressure cylinder device. The problems explained above in relation to the prior art are thus eliminated by the invention.

A pedal unit according to the invention for use in a double pedal device, in particular for the passenger side of a driving school vehicle has at least one pedal and a hydraulic pressure cylinder device which is mechanically coupled to the pedal and is symmetrical to an axis of symmetry, a slider which is mechanically coupled to the pedal and the pressure cylinder device for power transmission between the pedal and the pressure cylinder device, and a guide is provided on which the slider is movably supported such that only one force or force components act on the pressure cylinder device in the direction of the axis of symmetry of the pressure cylinder device when the force is transmitted from the pedal to the pressure cylinder device.

The guide preferably has at least one guide rod on which the slider is movably mounted, the slider being mounted on the guide rod with a linear bearing. The use of a linear bearing allows the slider to transmit only the linear, horizontal force component to the impression cylinder device.

The pedal unit on the passenger side preferably has at least two identical pressure cylinder devices, the axes of symmetry of which are arranged at a distance and parallel to one another in the same plane. This so-called tandem cylinder enables a large pedal stroke to be realized on the driver's side with a small and compact size of the pedal unit on the passenger's side.

The slider preferably consists of a plastic, in particular polyethylene, in order to provide sufficient elasticity of the slider in the event of temperature fluctuations.

An actuator for use in the double pedal device of the invention and for engaging a pedal on the driver side of a driving school vehicle has a hydraulic pressure cylinder. dereinrichtung and a movable driver device which is moved by the pressure cylinder device of the actuator and is in engagement with the pedal on the driver's side.

The driver device preferably has a driver which is at least partially coated with nylon or a similar low-friction material in order to prevent the pedal lever from being jammed or abraded on the driver.

Another actuator for use in the dual pedal device of the invention and for engaging a pedal on the driver's side of a driving school vehicle has a hydraulic pressure cylinder device and a transmission which causes movement of the pressure cylinder device of the actuator into movement of the pedal engaged with the actuator on the driver side implements. The gearbox can be used to convert a relatively small stroke of the pressure cylinder device on the driver side into a large adjustment of the coupled pedal.

The present invention also relates to a double pedal device for use in a driving school vehicle, in particular with an automatic transmission.

If a driving school vehicle has an automatic transmission, the pedal set on the driver's side has an accelerator pedal and a brake pedal. There is no clutch pedal in an automatic vehicle. If the driver learns to accelerate the accelerator pedal incorrectly, eg accelerating too hard in a curve, etc., dangerous situations can arise during the training trip. A double pedal device for a driving school vehicle should therefore enable the driver to correct an incorrect accelerator pedal actuation. A double pedal device of the invention which enables this correction is mentioned in claim 49. Accordingly, the double pedal device of the invention, which can be used in particular in a driving school vehicle with an automatic transmission, has an accelerator pedal on the driver's side, an accelerator pedal on the driver's side and a coupling device which couples the driver's accelerator pedal to the passenger's accelerator pedal in this way, that when the accelerator pedal on the passenger side is actuated, the accelerator pedal on the driver's side is also accelerated, an additional passenger-side anti-gas pedal being provided on the driver's instructor side and the coupling device coupling the driver-side accelerator pedal to the passenger-side anti-gas pedal in such a way that when the passenger-side anti-accelerator pedal is actuated, the driver Gas withdrawal is actuated.

This double pedal device of the invention with antigas thus has the decisive advantage that the driving instructor can bring back the gas by actuating the antigas pedal and thus can take back inadequate actuation of the accelerator pedal by the learner driver, which can also remedy dangerous situations when driving the driving school vehicle.

The coupling device of the invention can, for example, be a purely mechanical coupling device that works with cable pulls, for example. However, preference is given to a hydraulic system as a coupling device, which comprises a driver-side accelerator pedal hydraulic device which is in engagement with the driver-side accelerator pedal, a passenger-side accelerator pedal hydraulic device which is coupled to the passenger-side accelerator pedal, and a passenger-side anti-gas pedal hydraulic device which is coupled to the passenger-side anti-accelerator line and a pressure line - device that hydraulically connects the driver-side accelerator hydraulic device with the passenger-side accelerator pedal hydraulic device and the passenger-side anti-gas pedal hydraulic device.

The driver's accelerator hydraulic device, the passenger's accelerator hydraulic device and the passenger's anti-gas pedal hydraulic device preferably each have at least one pressure cylinder device.

The anti-gas pedal hydraulic device can have a slider, which is mechanically coupled to the passenger-side anti-gas pedal and the associated pressure cylinder device for power transmission between the anti-gas pedal and the pressure cylinder device, and have a guide on which the slider is movably mounted.

It is preferred here that only one force or force components acts on the pressure cylinder device in the direction of an axis of symmetry of the pressure cylinder device when the force is transmitted from the anti-gas pedal to the associated pressure cylinder device. This prevents jamming of a pressure cylinder rod.

The anti-gas pedal hydraulic device on the passenger side preferably has two pressure cylinder devices, the axes of symmetry of which are arranged at a distance and parallel to one another in the same plane. This so-called tandem cylinder has the advantage that a lifting movement of the anti-gas pedal into a twice as large stroke of a driver-side anti-gas actuator is made possible with a very compact and space-saving design of the anti-gas pedal hydraulic device. The driver's accelerator hydraulic device preferably has an actuator device on the driver's side of the vehicle which engages with the driver's accelerator and has at least one pressure cylinder device.

The actuator device can have a gas actuator for the gas increase and an anti-gas actuator for the gas withdrawal.

Furthermore, the accelerator pedal on the driver's side can be movable between a zero throttle position, in which no gas is given, and a full throttle position, in which full throttle is applied. The anti-throttle actuator moves the driver's accelerator pedal in the direction from the full throttle position to the zero throttle position when the passenger's side anti-gas pedal is operated, and the throttle actuator moves the driver's side accelerator pedal in the direction from the zero throttle position to the full throttle position when the passenger's accelerator pedal is operated.

The present invention also relates to a driving instructor stand for a driving school vehicle, in particular a truck or a bus, with a driving instructor seat, that is to say a vehicle seat for a driving instructor, in the driver's cell of the driving school vehicle.

Known driving instructors, especially in trucks or buses, which are also used for driving school purposes, generally use the passenger seat in the driver's compartment of the vehicle. In many cases, especially in the bus area, this front passenger seat is only designed as an emergency seat, which only offers insufficient, ergonomic conditions for the driving instructor. Or the passenger seat is so far away from the seat on the driver's side that the driving instructor can hardly control the learner driver during a training trip, which is too dangerous situations during the training trip. A driving instructor stand is therefore desired which improves the working conditions of the driving instructor.

This object is achieved by the driving school vehicle according to claim 116 or claim 117 and in particular by the driving instructor stand according to claim 72, claim 88, claim 94, claim 95, claim 101 or claim 114. Accordingly, the driving instructor stand according to the invention for a driving school vehicle, in particular for a truck or a bus, has a driving instructor seat, i.e. a vehicle seat for the driving instructor, in the driver's cell of the driving school vehicle and a pedal device on the driving instructor side of a double pedal device for actuation by the driving instructor, the driving instructor-side pedal device having a Driver-side pedal device for controlling the driver-side pedal device of the double pedal device is coupled and a distance between the vehicle seat and the driver's-side pedal device is adjustable. Due to the adjustability of the distance between the driving instructor seat and the pedal device, the driving instructor stand can be adapted to the physical dimensions of the respective driving instructor. This gives the driving instructor a more relaxed and comfortable posture during the training trip, which also contributes to an improved concentration of the driving instructor.

The vehicle seat of the driving instructor and / or the pedal device of the driving instructor stand can be arranged in a longitudinal direction of the driving school vehicle so as to be displaceable relative to one another in the driver's cell of the driving school vehicle for changing the distance between the vehicle seat and the driving instructor-side pedal device. The driving instructor seat can preferably be arranged on or in rails or grooves of the floor assembly of the vehicle which extend parallel to one another and can then be displaced thereon. The pedal group on the driver's side can be fixed to the floor group or the pedal device can also be designed to be displaceable or easily displaceable. For example, the pedal device can be attached to the floor assembly by means of an easily detachable Velcro device. If the distance between the pedal device and the seat is to be changed, the Velcro connection can then simply be released and the pedal device can be arranged in the new position with the changed distance from the seat as desired. The Velcro surface on the floor assembly of the vehicle is designed to be larger in area than the Velcro surface on the pedal device in order to enable a corresponding setting option for the distance between the seat and the pedal assembly.

The driving instructor seat preferably has a seating surface which is raised compared to the seating surface of the driver's seat in order to give the driving instructor a better overview of what is going on and the driving activity of the student.

The driving instructor seat preferably has a seat part and a gas spring device on which the seat part is mounted. The gas suspension or air suspension enables the driving instructor to sit comfortably and also allows the seat to be adjusted in height by means of a height adjustment device for adjusting the height of the driving instructor seat above the floor assembly of the driving school vehicle.

The driving instructor seat can also have a backrest part and a pivoting device for adjusting the inclination of the backrest part with respect to the seat surface of the seat part, so that a further adjustment possibility and thus an even more comfortable one or even more ergonomic sitting position of the driving instructor.

The pedal device on the driver's side is preferably coupled to the driver side pedal device via a hydraulic device. Furthermore, the hydraulic device can have at least one flexible pressure line for transmitting a control pressure to the driver's pedal. The use of flexible pressure lines in the hydraulic device has the advantage that the pedal device on the driver's side can easily be moved in adaptation to the driver's seat, without installation work being necessary for the re-routing of the coupling lines between the pedal groups.

The driving instructor seat preferably has a holder to which the pedal device on the driving instructor side is attached or can be attached. This has the advantage that the driving instructor's seat and pedal device form a unit that can be installed in the driving school vehicle practically in one operation and can also be easily removed from it. Once set or set, the position of the pedal device relative to the seat on the bracket can then be maintained. The same driving instructor then does not have to set up the driving instructor stand every time it is installed in the vehicle. In this regard, it is also preferred that the holder has a device for adjusting the distance between the driving instructor seat and the driving instructor-side pedal device or is easily adjustable.

The pedal device on the driving instructor side can be movably attached to the holder for adjusting the distance between the driving instructor seat and the pedal device on the driving instructor side. The holder for the pedal device on the driving instructor side is preferably attached to the seat part of the driving instructor seat; this enables the pedal device to always maintain a set position relative to the seat surface, even if the seat itself should be adjusted in height.

The holder can have a guide in which the pedal device on the driver's side can be moved and locked. Furthermore, the pedal device on the driver's side can be inserted into and removed from the guide.

The present invention also relates to a driving instructor stand for a driving school vehicle, in particular a truck or a bus, with a vehicle seat for the driving instructor in the driver's cell of the driving school vehicle and a pedal device for actuation by the driving instructor, the driving instructor-side pedal device with a driver-side pedal device for controlling the driver-side Pedal device is coupled and a display device, in particular an electronic display device, is provided, which shows the driving instructor at least one view of the surroundings of the driving school vehicle.

The display device has the considerable advantage that the driving instructor can fully grasp the respective driving situation, even if his viewing angle on the exterior mirrors is different from that of the student or only to a limited extent. The driving instructor can use the display device e.g. monitor the blind spot. This therefore contributes significantly to making driving school operations safer.

The display device can have several display fields, each of which displays a view of the surroundings of the driving school vehicle. For example, a left-side, right-side view of the surroundings, a rear view and / or a front view of the driving school vehicle and its surroundings are displayed, whereby the monitoring options of the driving instructor are improved.

The driving instructor station preferably has a coupling device, e.g. an easily pluggable connection or plug connection with corresponding plugs and cables that couples or connects the display device to a video camera or a plurality of video cameras attached to the driving school vehicle, which capture the surrounding view or views of the driving school vehicle, for displaying the surrounding views on the display device.

The display device is preferably attached to the driving instructor seat in order to enable a driving instructor stand in one unit. The holder for the display device can e.g. be attached to the seat part of the driver's seat.

The present invention also relates to a driving instructor stand or a driving instructor seat device for a driving school vehicle, in particular a truck or a bus, with a vehicle seat for the driving instructor in the driver's cell of the driving school vehicle, the driving instructor seat in a central region between a driver seat and a front passenger seat on the underbody of the driving school vehicle is arranged or attached.

Known driving instructors, especially in trucks or buses, which are also used for driving school purposes, generally use the passenger seat in the driver's compartment of the vehicle. In many cases, especially in the bus area, this front passenger seat is only designed as an emergency seat, which only offers insufficient, ergonomic conditions for the driving instructor. Or the passenger seat is from the seat on the driver's side far enough away that the driving instructor can hardly control the learner driver during a training trip, which can lead to dangerous situations during the training trip. It is therefore desirable to have a driving instructor stand that improves the working conditions of the driving instructor and thereby also increases safety in driving school operations.

This object is achieved by the driving instructor station according to claim 94, claim 95, claim 101 or claim 114. Accordingly, the driving instructor stand of the invention for a driving school vehicle, in particular for a truck or a bus, has a driving instructor-side pedal device for actuation by the driving instructor, the pedal device being coupled with at least one driver-side pedal device for controlling the driver-side pedal device, which together form a double pedal device has a pedal, and a footrest for the driving instructor, which is arranged in an area above the pedal.

The driving instructor station of the invention for a driving school vehicle, in particular a truck or a bus, has a driving instructor-side control unit which is coupled to an electrical system of the driving school vehicle for controlling the driving operation.

The driving instructor station or the double pedal device of the invention for a driving school vehicle, in particular a truck or a bus, has a driving instructor-side pedal device for actuation by the driving instructor, the pedal device being coupled to a driver-side pedal device for controlling the driver-side pedal device, and a pedal linkage of the pedal device from one folded, flexible cuff is surrounded. Further advantageous developments of the present invention can be found in the subclaims.

In Fig. 2, an actuator 10 is shown in a detached, perspective and partially cut view. The actuator 10 comprises a cylindrical, hollow actuator housing 14 which is open at the end, a pressure cylinder 11, which extends at least partially in the cavity of the actuator housing 14 concentrically to the axis of the actuator housing 14, a piston rod 18 or a piston rod, which is connected to the pressure cylinder 11 is coupled in terms of pressure inside the actuator housing 14 via a pressure cylinder piston (not shown) and is fixedly connected at its other end to a driver cylinder 17 which fits movably into the cavity of the actuator housing 14 and can be moved back and forth along the axis of the actuator housing 14 , and a spring 16 extending between the other end of the actuator housing 14 concentric with the axis of the actuator housing 14, ie more precisely between the driver cylinder 17 and an actuator holder 19 made of plastic, which closes the other end of the actuator housing 14.

The pressure cylinder 11 consists of a stainless steel or aluminum and is hydraulic at one end via a hollow screw 13 which is fastened at the end to the pressure cylinder 11 and has a screw-in threaded connection, with an associated pressure line of the hydraulic coupling device connected. The pressure cylinder 11 is arranged concentrically to the axis of the actuator housing 14 in the cavity of the actuator housing 14. At the end area towards the hollow screw 13, the pressure cylinder 11 has on its outer surface radially, annularly extending grooves 12, in which pins 20, which pass through corresponding holes in the wall of the actuator housing 14, engage in order to fix the pressure cylinder 11 on the actuator housing 14 ,

2, the pressure cylinder 11 has a total of five of these radial grooves 12, two adjacent grooves not being visible in FIG. 2, since they are covered by the wall of the actuator housing 14, but are in engagement with the two locking pins 20 shown ,

When the actuator 10 is set up, the radial grooves 12 and the pins 20 interacting with it can be used to determine how far the pressure cylinder 11 extends into the actuator housing 14 or protrudes from it at the end, whereby on the one hand the position of a driver 15 along the actuator housing 14 in its starting position, in which there is no pressurization of the pressure cylinder 11, can be adjusted and thus the maximum stroke of the driver 15 of the actuator 10 can be adjusted to match the given design of the associated pedal. The actuator 10 can thus be adapted to the pedals of different vehicle types and vehicles with different pedal strokes.

Inside the pressure cylinder 11 there is a pressure piston, not shown, on which the hydraulic pressure prevailing in the pressure cylinder acts. The pressure piston is sealed and movable in the interior of the pressure cylinder 11, so that no hydraulic fluid escapes from the pressure cylinder 11. can give way. The pressure piston is connected within the pressure cylinder 11 to a piston rod 18 which protrudes from the pressure piston 11 in the interior of the actuator housing 14 and extends concentrically to the axis of the cylindrical actuator housing 14.

At the other end of the piston rod 18 or the piston rod, the driver cylinder 17, which can be moved back and forth in the interior of the actuator housing 14 along the axis of the actuator housing 14, is accommodated and moves in dependence on the pressurization of the hydraulic pressure cylinder 11. The driver cylinder 17 can be made of stainless steel or aluminum or a plastic and is preferably designed to be solid.

On the outer surface of the driver cylinder 17, the driver 15 is attached, which has a hook-shaped U crack in elevation, the opening of the hook-shaped driver 15 pointing to the end of the actuator housing 14 with the actuator holder 19. The driver 15 has a driver leg that extends parallel to the axis of the actuator housing 14 and a driver base that is attached to the driver cylinder 17. The driver can be provided with plastic, in particular nylon, on its surface.

The driver opening, that is to say the region between the outer wall of the actuator housing 14 and the surfaces of the driver 15 adjoining the driver opening, is designed such that the pedal lever with which the actuator 10 is coupled fits into the driver opening of the driver 15 for safe actuation ensure the assigned pedal or pedal lever. In the cavity of the actuator housing 14 between the actuator bracket 19 and the driver cylinder 17, the spring 16, which is designed as a compression spring, is housed, which presses the movable driver cylinder 17 in the cavity of the actuator housing 14 in the direction of the pressure cylinder 11.

The actuator bracket 19 is fitted at the corresponding end of the actuator housing 14 in its cavity and at the same time closes the corresponding end of the actuator housing 14. The actuator bracket 19 serves on the one hand as a counter bearing for the spring 16 and on the other hand for attaching or fastening the actuator 10 to the Body of the motor vehicle on the driver's side in the pedal area or on a specially provided base plate 96, which is installed or housed in the pedal area of the vehicle on the driver's side. The actuator holder 19 can also be designed as a joint in order to articulate the actuator 10 on the body or the base plate 96 in the pedal area on the driver's side.

In the wall of the actuator housing 14 there is a slot 21 which extends parallel and along the axis of the actuator housing 14 and through which the driver 15 protrudes from the actuator cylinder 17 from the actuator housing 14. The clear width of the slot 21 or the recess is adapted to the thickness or dimension of the driver 15 in such a way that the driver 15 can freely move back and forth in the slot 21. The length of the slot 21 corresponds at least to the maximum permissible stroke of the driver 15. The dimensions of the slot 21 can also be such that the driver 15 is guided through the slot walls. If the pressure cylinder 11 of the actuator 10 is pressurized by actuation of the associated pedal on the passenger side, ie by the driving school teacher, the piston rod 18 and thus the driver cylinder 17 and the driver 15 move in the direction of the actuator holder 19 against the compressive force of the spring 16, whereby the engaged pedal is operated on the driver's side. If the actuation of the pedal on the passenger side is then withdrawn, the hydraulic pressure in the pressure cylinder 11 also decreases and the driver cylinder 17 together with the driver 15 is moved by the spring 16 in the opposite direction, ie towards the pressure cylinder 11, until equilibrium is reached there is between the pressure force of the pressure cylinder 11 and the pressure force of the spring 16. If the driving instructor takes the pedal pressure or the pedal actuation back further until there is no pedal actuation on the passenger side, the spring 16 pushes the driver cylinder 17 together with the driver 15 ever further in the direction of the pressure cylinder 11 until the driver 15 in its initial position in which there is no longer any pressurization by the pressure cylinder 11 but only a pressurization by the spring 16.

FIG. 3 shows an actuator 30 in a view corresponding to FIG. 2. The actuator 30 has an actuator housing 34 with a pressure cylinder 31 with radially surface-extending grooves 32 and a closing hollow screw 33, a driver 35 or carrier which protrudes from the actuator housing 34, a spring 36 which is designed as a compression spring, and one movable cylinder 37 inside the actuator housing 34, which is connected at one end to a piston rod (not visible in FIG. 3) which projects into the pressure cylinder 31 and is connected to a pressure piston inside the pressure cylinder 31. The impression cylinder 31 is in turn adjustable and attachable to the actuator housing 34 via the grooves 32 and the locking pins 40.

The structure and function of elements 31, 32, 33, 34, 36, 39 of an actuator bracket and slot 51 are identical to the structure and function of the corresponding elements of actuator 10 shown in FIG. 2. For a detailed description of the structure and function of these elements, reference is therefore made to the above explanations with regard to FIG. 2.

In contrast to the actuator 10 of FIG. 2, the actuator 30 of FIG. 3 has no driver but is connected via a chain 41 to an assigned pedal lever or driver's pedal. The structure of the actuator 30 with chain 41 is described in detail below.

A chain holder 42, which is designed as a cuboid block, is placed or pushed onto the cylindrical actuator housing 34 of the actuator 30. The chain bracket 42 is clamped to the actuator housing 34 of the actuator 30 by means of a clamping screw 43. 8 shows a narrow gap 52 in the lower region of the chain holder 42, which enables clamping by means of the clamping screw 43 on the circumference of the actuator housing 34. Before the chain holder 42 is clamped, the chain holder 42 can be displaced on the circumference of the cylindrical actuator housing 34 and can therefore be adjusted in its final position. The position of the chain holder 42 on the actuator housing 34 is fixed by the clamping along the length of the actuator housing 34. In the upper part or section of the block-like or cuboid chain holder 42, a compartment 44 is provided which opens outwards via the corner of the chain holder 42 shown or is accessible from the outside. There is a in the compartment 44 first gear 45 or pinion around a shaft 46 or rotatably arranged with the shaft 46. The chain 41 is held at one of its ends on the chain holder 42 with a chain attachment 47.

A carrier 35 is connected to the cylinder 37 and protrudes from the actuator housing 34 through the slot 51. The hook-shaped driver 15 of FIG. 7 is used here as the carrier 35 in FIG. 3. A cylindrical gear housing 48 is fastened to the carrier 35, in which a further gear 49 is rotatably arranged or mounted. In the wall of the gear housing 48 two slots 48.1 are cut out at a distance from one another, through which the chain 41 passes.

The chain 41 extends from the chain attachment 47 on the chain holder 42 in the direction of the gear housing 48, which is connected to the carrier part 35. The chain 41 is placed around the gear 49 and extends through one of the slots 48.1 into the gear housing 48 and through the other of the slots 48.1 out of the gear housing 48 and is thus deflected by the gear 49 through 180 °. The chain 41 extends from the gear housing 48 in the direction of the chain holder 42 and enters the compartment 44, passes the toothed wheel 45, which engages in the chain links of the chain 41, and leaves the compartment 44 after being deflected by 90 degrees , Coming from compartment 44, the chain extends to the assigned pedal or pedal lever, on which the chain with its end link, e.g. is fastened with a clamp.

If the pressure cylinder 31 is pressurized against the force of the spring 36, the cylinder 37 is moved in the direction of the actuator holder 39. The carrier 35 with the gear housing 48 then also moves with the cylinder 37, whereby the chain 41 is pulled away from the chain bracket 42 toward the actuator bracket 39. This movement is implemented via the gear 49 on the attachment of the chain 41 to the pedal, whereby the pedal is deflected or actuated by the chain pull.

If the pressure in the pressure cylinder 31 decreases, the cylinder 37 together with the carrier 35 and the gear housing 48 is pushed back by the spring 36 in the direction of the chain holder 42, whereby the chain length between the chain holder 42 and the gear 49 or the gear housing 48 is shortened and thus the actuation of the coupled pedal is withdrawn.

Due to the 180 ° deflection of the chain 41 by the gear 49, a stroke of the pressure cylinder 31 or the stroke of the cylinder 37 in the actuator housing 34 and the carrier 35 with the gear housing 48 in a double the stroke of the chain portion of the chain 41 between the Chain bracket 42 and the pedal implemented, whereby large pedal deflections or strokes can be performed with the actuator 30.

1 shows a pedal unit 80 arranged on the passenger side in accordance with a preferred embodiment of the present invention.

The pedal unit 80 comprises two hydraulic pressure cylinders 69, 68 with an identical structure, which are arranged at a distance from one another and parallel to one another, pressure piston rods 70 and 71 with an identical structure, compression springs 68 and 67 with an identical structure, guide rods 66 and 65 with an identical structure, a hydraulic block 64, a slider 63 or slide, which is mounted to move back and forth on the guide rods 66 and 65, which is illustrated in FIG. 1 by the double arrow shown. is light, an end block 62 in which the pedal lever 60 is pivotally articulated, and a support lever 61 which is articulated on the pedal lever 60 and on the slider 63 and thus connects the slider 63 with the pedal lever 60, so that movement a pedal lever 60 can be transferred to the slider 63 via the support lever 61.

The pedal lever 60 engages at one end in a recess in the end block 62, in which a pin runs, about the longitudinal axis of which the pedal lever 60 is pivotable or rotatable. The recess in the end block 62 is dimensionally designed such that there is sufficient freedom of movement of the end of the pedal lever 60 mounted in the end block 62. At the opposite end of the pedal lever 60, a flat pedal disk is attached, which enables foot actuation by the passenger or driving school teacher.

The support lever 61 is articulated to the pedal lever 60 such that a movement of the pedal lever 60 is converted to a movement of the support lever 61. The other end of the support lever 61 engages in a slot-shaped recess 63.1 (cf. FIG. 5) in the slider 63 and is in turn rotatably or pivotably mounted in this recess around a cross pin, the cross pin of the slider 63 being used for mounting the support lever 61 is aligned parallel to the bearing pin in the end block 62 for the storage of the pedal lever 60. In addition, the cross pin for the mounting of the support lever 61 in the slider 63 and also the bearing pin for the mounting of the pedal lever 60 in the end block 62 are aligned perpendicular to a direction of movement of the slider 63 on the guide rods 65 and 66.

The block-like slider 63 is mounted on the guide rod 66 with a linear bearing 72 and movably supported on the guide rod 65 with a second linear bearing 74. The two the linear bearings 72 and 74 are fitted and housed in through bores or channels with a circular cross-section of the slider 63 and enable the slider 63 to be linearly supported on the guide rods 66 and 65. The slider 63 is made, for example, of polyethylene (type Simona PE-HWST according to ISO) 10285). For example, a linear ball bearing with raceway plates (type SKF LBBR12-2LS) is used as the linear bearing 72 or 74.

In the slider 63, pressure piston rods 70 and 71 extending parallel to one another are also fastened with their ends free of pressure pistons. A movement or displacement of the slider 63 on the guide rods 66 and 65 is thus implemented directly on the pressure piston rods 70 and 71.

The pressure piston rods 70 and 71 engage in the pressure cylinders 69 and 68, the pressure piston rod 70 projecting into the pressure cylinder 69 and the pressure piston rod 71 projecting into the pressure cylinder 68. At the ends of the pressure piston rods 70 and 71 located in the pressure cylinders 69 and 68 there are pressure pistons which are movably sealed in the corresponding pressure cylinders 69 and 68, respectively. A movement of the pressure piston rods 70 and 71 is implemented on the corresponding pressure pistons and thus also exerted on the liquid column in the pressure cylinders.

The two pressure cylinders 69 and 68 extend parallel to one another and are fastened in the hydraulic block 64, for example by corresponding screw connections. The outputs of the two pressure cylinders 68 and 69 are combined via a channel 64.1 in the hydraulic block 64 to form an access to the hydraulic block 64 provided with a hollow screw 64.2 (cf. FIG. 5). The parallel guide rods 66 and 65 are fixedly connected at one end to the hydraulic block 64, for example by appropriate screw connections, extend further through the slider 63, namely through the linear bearings 72 and 74, and extend further to the end block 62 with which they are firmly connected, again, for example, by screw connections. A compression spring 68 is installed between the slider 63 and the hydraulic block 64, which winds helically around the guide rod 66. The compression spring 68 or coil spring is attached or screwed to the hydraulic block 64 at one end, while the other end of the compression spring 68 is screwed to the slider. The compressive force of the compression spring 68 moves the slider 63 away from the hydraulic block 64 in the direction of the end block 62 when there is no counterforce by the pedal lever 60. Another compression spring 67 or coil spring is on the guide rod 65 between the slider 63 and the hydraulic block 64 arranged and attached to it like the compression spring 68. The pressure force of the compression spring 67 also tends to move the slider 63 away from the hydraulic block 64 in the direction of the end block 62.

A spacer sleeve 73 is pushed onto the guide rod 66 between the slider 63 and the end block 62. An identical spacer sleeve 73 is also pushed onto the guide rod 65 between the slider 63 and the end block 62. The two spacer sleeves 73 are constructed identically to one another and have the purpose of restricting the movement of the slider 63 towards the end block 62, that is to say that the slider 63 strikes the spacer sleeves 73 if only the compressive forces of the two springs 68 and 67 are without Counteracting pedal actuation. The slider 63 is then in the position shown in FIG. 1. The fictitious axis of symmetry F of the pressure cylinder 69 and the fictitious axis of symmetry of the pressure piston rod 70 coincide. The fictitious axes of the pressure cylinder and the pressure rod 71 also coincide. The axes of the two pressure cylinders 69 and 68 are aligned exactly parallel to one another. In addition, the axes of the guide rods 66 and 65 are aligned parallel to one another and lie together with the axes of the pressure cylinders 69 and 68 in a common plane. The support lever 61 is mounted in the center of the slider 63, so that forces occurring when the pedal is actuated are distributed evenly between the two cylinder pistons 70 and 71 via the slider 63. The pedal lever 60 is also mounted centrally on the end block 62 between the guide rods 66 and 65.

The pedal unit 80 is preferably fastened on a plate 100, which in turn rests on the passenger side of the vehicle on the floor in the passenger area and is preferably fastened there with a Velcro connection. The pedal unit 80 can therefore be easily assembled and disassembled due to the Velcro connection required alone. The pedal unit 80 or its mounting plate 100 can also be screwed to the floor. The Velcro connection is sufficient since the force acting on the pedal lever 60 when the pedal is actuated is transmitted to the slider 63 via the pedal lever 60 and the support lever 61 in such a way that a linear force component, that is to say a force component in the direction of movement of the slider 63, is produced, and also one Force component arises which acts perpendicular to the direction of movement of the slider 63, that is to say toward the vehicle floor, as a result of which the pedal unit 80 is pressed vertically onto the vehicle floor when the pedal is actuated and therefore no tilting forces can act on the pedal unit 80 when the pedal is actuated. A preferred embodiment of the double pedal device of the invention for a driving school vehicle is shown by way of example in FIGS. 4 and 5, wherein in FIG. 4 the pedal set or the pedal device 90.5 on the driver side of the motor vehicle and in FIG. 5 the second pedal set or the pedal device 80.5 on the Passenger side is shown, ie on the side of the driving instructor.

The first pedal set 90.5 on the driver's side comprises, as usual, an accelerator pedal 95, a brake pedal 94 and a clutch pedal 93, an actuator 10 according to FIG. 2, the driver 15 of which engages with a pedal lever 93.1 of the pedal 93, a further actuator 30 which is shown in more detail in Fig. 3, the chain 41 at its end on a pedal lever 94.1 of the pedal 94, for example is fixed with a clamp, and another actuator 10.1, which has the same structure as the actuator 10 of FIG. 2 and its driver 15.1 with a pedal lever 95.1 of the pedal 95 in engagement.

An actuator plate 96 is provided, on which the actuator 10 is fastened with the actuator holder 19, on which the actuator 30 is fastened with its holder 39 and on which the actuator 10.1 is also fastened with its actuator holder.

The pressure cylinder 11 of the actuator 10 is connected to the hydraulic pressure line 92 in a fluid-continuous manner via the hollow screw 13, which closes the pressure cylinder 11. The pressure cylinder 31 of the actuator 30 is fluidly connected to a pressure line 91 via the hollow screw 33. The pressure cylinder 11.1 of the actuator 10.1 is also fluidly connected to a pressure line 90. The second pedal set 80.5 on the passenger side has a housing, which is not shown, and also has three pedals 97, 98, 99 according to FIG. 5, the pedal 97 being the accelerator pedal, the pedal 98 the brake pedal and the pedal 99 the clutch pedal , The second pedal set has a pedal unit 80, which is described in more detail in FIG. 1, a further pedal unit 80.1, which corresponds to the pedal unit 80 described in FIG. 1, and a third pedal unit 81, which, in contrast to the pedal units 80 and 80.1, only has a single pressure cylinder with pressure piston rod, a single guide rod with compression spring, a correspondingly adapted slider, hydraulic block and end block with support lever connection to the pedal 97.

The hydraulic block 64 of the pedal unit 80 is continuously connected to the pressure line 92 via the hollow screw 64.2, which has a screw-in connector. The hydraulic block of the pedal unit 80.1 is connected to the pressure line 91 via its hollow screw. The hydraulic block of the pedal unit 81 is also connected to the pressure line 90 via a hollow screw.

The hydraulic devices used, that is to say the passenger-side pressure cylinder devices shown in FIG. 5, each having a pressure cylinder with a pressure piston rod, the pressure cylinder devices of the actuators 10, 10.1 and 30 shown in FIG. 4, each also having a pressure cylinder and an associated pressure piston rod , the flexible pressure lines 90, 91 and 92 and the hydraulic blocks 64 on the passenger side are filled with a hydraulic fluid. Hydraulic oil, fork oil or white oil can be used as the hydraulic fluid. A hydraulic fluid with a viscosity number of 1 is preferably used in order to delay the reaction the hydraulic liquid column to avoid pressure changes. A preferred white oil is of the type Renolin MR1VG5 and has a viscosity number of 1. The pressure lines are, for example, microfluid hose lines made of synthetic resin fiber (eg type EMMKT8 PN500 PB 800 DN 2).

When the pedal 99 on the driving instructor side is actuated, the slider 63 is displaced in the direction of the hydraulic block 64, the piston rods 70 and 71 exerting pressure on the liquid column in the pressure cylinders 69 and 68. This pressure is transferred from the hydraulic block 64 into the pressure line 92 within the liquid column ¹ and finally coupled into the pressure cylinder 11 of the actuator 10 via the hollow screw 13. The pressure piston rod 18 then moves the cylinder 17 with the driver 15. Since the driver 15 is in engagement with the pedal lever 93.1 of the pedal 93, the pedal 93 is deflected. If the pressure on the pedal 99 is withdrawn or given up, the spring 16 of the actuator 10 pushes the cylinder 17 with the driver 15 and thus also the pressure piston rod 18 back. The slider 63 of the pedal unit 80 is moved back to its starting position by the spring force of the two springs 67 and 68 but also by the change or the suction pressure in the pressure cylinders, ie to the stop position on the sleeves 73.

If the pedal 98 is actuated on the passenger side, the pressure on the liquid column via the two pressure cylinders and the hydraulic block of the pedal unit 80.1, which has the same structure as the pedal unit 80, propagates onto the pressure line 91 and from there into the pressure cylinder 31 Actuator 30. The carrier 35 with gear housing 48 is consequently displaced, as a result of which the chain section between the chain holder 42 and the pedal lever 94.1 is shortened and the pedal 94 is deflected. If the actuation of the Pedals 98 withdrawn or abandoned on the passenger side, the pedal 94 is returned to its rest position by its pedal return spring (not shown), whereby tension is exerted on the chain 41, which is connected to the pedal lever 94.1 of the pedal 94, and thereby the wearer 35 together with the gear housing 48 is now pulled back in the direction of the chain holder 42. The resulting pressure on the liquid column is returned via the pressure cylinder of the actuator 30 and the pressure line 91 to the passenger side, namely to the hydraulic block of the pedal unit 80.1, whereby the pressure cylinders of the pedal unit 80.1 together with the pressure springs of the pedal unit 80.1 move the slider to its initial position move back. Similar processes also occur when the pedal 97 is actuated via the pedal unit 81, the pressure line 90 and the actuator 10.1, which is coupled to the pedal lever 95.1.

A further preferred embodiment of the double pedal device of the invention for a driving school vehicle with an automatic transmission is explained below with reference to FIGS. 6, 7, 8, 9 and 10.

FIG. 7 shows an actuator 10.2, which is identical in construction as an anti-gas actuator 10.12 and also as a gas actuator 10.22 of an actuator device 10.32 of a driver-side accelerator pedal hydraulic device (cf. also FIG. 9), in a detached, perspective and partially cut-open view , The actuator 10.2 comprises a cylindrical, hollow actuator housing 14.2, which is open at the end, a pressure cylinder 11.2, which extends at least partially in the cavity of the actuator housing concentrically to the axis of the actuator housing, a piston rod 18.2 or a piston rod, which is connected to the pressure cylinder 11.2 inside the actuator housing 14.2 via a not shown Pressure cylinder piston is coupled in terms of pressure, and is fixedly connected at its other end to a driver cylinder 17.2, which fits movably into the cavity of the actuator housing 14.2 and can be moved back and forth along the axis of the actuator housing 14.2, a spring 16.2 which is located between the other end of the actuator housing 14.2 concentric to the axis of the actuator housing 14.2, ie more precisely between the driver cylinder 17.2 and an actuator holder 19.2 made of plastic, which closes the other end of the actuator housing 14.2.

The pressure cylinder 11.2 consists of a rustproof stainless steel or aluminum and is hydraulically connected at one end to an associated pressure line of the hydraulic coupling device via a hollow screw 13.2 which is fastened at the end to the pressure cylinder 11.2 and has a screw-in threaded connection. The pressure cylinder 11.2 is arranged concentrically to the axis of the actuator housing 14.2 in the cavity of the actuator housing 14.2. At the end area towards the hollow screw 13.2, the pressure cylinder 11.2 has on its outer surface radially, annularly extending grooves 12.2, in which pins 20.2, which pass through corresponding holes in the wall of the actuator housing 14.2, engage in order to fix the pressure cylinder 11.2 on the actuator housing 14.2 ,

7, the pressure cylinder 11.2 has a total of five of these radial grooves 12.2, two adjacent grooves not being visible in FIG. 7, since they are covered by the wall of the actuator housing 14.2, but are in engagement with the two locking pins 20.2 shown ,

When setting up the actuator 10.2, it can be determined by means of the radial grooves 12.2 and the pins 20.2 interacting with them how far the pressure cylinder 11.2 extends into the Actuator housing 14.2 extends into or protrudes from this end, whereby on the one hand the position of the driver 15.2 along the actuator housing 14.2 in its starting position, in which there is no pressurization of the pressure cylinder 11.2, can be set, and thus also the maximum stroke of the driver 15.2 of the actuator 10.2 can be adjusted to match the given design of the assigned pedal. The actuator 10.2 can thus be adapted to the pedals of different vehicle types and vehicles with different pedal strokes.

Inside the pressure cylinder 11.2 there is a pressure piston, not shown, on which the hydraulic pressure prevailing in the pressure cylinder acts. The pressure piston is sealed and movable in the interior of the pressure cylinder 11.2, so that no hydraulic fluid can escape from the pressure cylinder 11.2. The pressure piston is connected within the pressure cylinder 11.2 to a piston rod 18.2 which protrudes from the pressure piston 11.2 in the interior of the actuator housing 14.2 and extends concentrically to the axis of the cylindrical actuator housing 14.2.

At the other end of the piston rod 18.2 or the piston rod, a driver cylinder 17.2, which can be moved back and forth in the interior of the actuator housing 14.2 along the axis of the actuator housing 14.2 and which moves in dependence on the pressurization of the hydraulic pressure cylinder 11.2. The driver cylinder 17.2 can be made of stainless steel or aluminum or a plastic and is preferably designed to be solid.

On the outer surface of the driver cylinder 17.2, the driver 15.2 is attached, which is a hook-shaped in elevation Outlines, the opening of the hook-shaped driver 15.2 points to the end of the actuator housing 14.2 with the actuator bracket 19.2. The driver 15.2 has a driver leg, which extends parallel to the axis of the actuator housing 14.2, and a driver base, which is attached to the driver cylinder 17.2. The driver can be provided with plastic, in particular nylon, on its surface.

The driver opening, that is to say the region between the outer wall of the actuator housing 14.2 and the surfaces of the driver 15.2 adjacent to the driver opening, is designed such that the pedal lever with which the actuator 10.2 is coupled fits into the driver opening of the driver 15.2 for safe actuation ensure the assigned pedal or pedal lever.

A spring 16.2, which is designed as a compression spring, is housed in the cavity of the actuator housing 14.2 between the actuator holder 19.2 and the driver cylinder 17.2 and presses the movable driver cylinder 17.2 in the cavity of the actuator housing 14.2 in the direction of the pressure cylinder 11.2.

The actuator bracket 19.2 is fitted at the corresponding end of the actuator housing 14.2 in its cavity and at the same time closes the corresponding end of the actuator housing 14.2. The actuator bracket 19.2 serves on the one hand as a counter bearing for the spring 16.2 and on the other hand for attaching or fastening the actuator 10.2 to the body of the motor vehicle on the driver's side in the pedal area or on a specially provided base plate which is installed in the pedal area of the vehicle on the driver's side or is housed. The actuator mounting 19.2 can also be used as a be designed to steer the actuator 10.2 articulated to the body of a base plate in the pedal area on the driver's side.

In the wall of the actuator housing 14.2 there is a slot 21.2 which extends parallel and along the axis of the actuator housing 14.2 and through which the driver 15.2 protrudes from the actuator cylinder 17.2 from the actuator housing 14.2. The clear width of the slot 21.2 or the recess is adapted to the thickness or dimension of the driver 15.2 such that the driver 15.2 can move freely back and forth in the slot 21.2. The length of the slot 21.2 corresponds at least to the maximum permissible stroke of the driver 15.2. The dimensions of the slot 21.2 can also be designed such that the driver 15.2 is guided through the slot walls.

If the pressure cylinder 11.2 of the actuator 10.2 is pressurized by actuating the assigned pedal on the passenger side, ie by the driving school teacher, the piston rod 18.2 and thus the driver cylinder 17.2 and the driver 15.2 move in the direction of the actuator holder 19.2 against the pressure force of the spring 16.2, whereby the engaged pedal, here for example the driver's accelerator pedal, is operated on the driver's side. If the actuation of the pedal on the passenger side is then withdrawn, the hydraulic pressure in the pressure cylinder 11.2 also decreases and the driver cylinder 17.2 together with the driver 15.2 is moved by the spring 16.2 in the opposite direction, ie towards the pressure cylinder 11.2, until equilibrium is reached there is between the pressure force of the pressure cylinder 11.2 and the pressure force of the spring 16.2. If the driving instructor takes the pedal pressure or the pedal actuation i further back until there is no pedal actuation on the passenger side, the spring 16.2 pushes the driver cylinder 17.2 together with the driver 15.2 in the direction of the pressure cylinder 11.2 until the driver 15.2 in it The starting position is in which there is no longer any pressurization by the pressure cylinder 11.2, but only a pressurization by the spring 16.2.

An actuator 30.2 is shown in FIG. 8 in a view corresponding to FIG. 7. The actuator 30.2 has an actuator housing 34.2 with a pressure cylinder 31.2 with radially surface-running grooves 32.2 and a final hollow screw 33.2, a driver 35.2 or carrier which protrudes from the actuator housing 34.2, a spring 36.2, which is designed as a compression spring, and a movable cylinder 37.2 inside the actuator housing 34.2, which is connected at one end to a piston rod 38.2 which projects into the pressure cylinder 31.2 and is connected to a pressure piston in the interior of the pressure cylinder 31.2. The pressure cylinder 31.2 is in turn adjustable and attachable to the actuator housing 34.2 via the grooves 32.2 and the locking pins 40.2.

The structure and function of elements 31.2, 32.2, 33.2, 34.2, 36.2, 39.2 and 51.2 are identical to the structure and function of the corresponding elements of actuator 10.2, which is shown in FIG. 7. For a detailed description of the structure and function of these elements, reference is therefore made to the above explanations with regard to FIG. 7.

In contrast to the actuator 10.2 of FIG. 7, the actuator 30.2 of FIG. 8 has no driver but is connected via a chain 41.2 with an associated pedal lever or driver's soapy pedal, here the driver's brake pedal. The structure of the actuator 30.2 with chain 41.2 is described in detail below.

A chain holder 42.2, which is designed as a cuboid block, is placed or pushed onto the cylindrical actuator housing 34.2 of the actuator 30.2. The chain bracket 42.2 is clamped to the actuator housing 34.2 of the actuator 30.2 by means of a clamping screw 43.2. 8 shows a narrow gap 52.2 in the lower region of the chain holder 42.2, which enables clamping by means of the clamping screw 4.3.2 on the circumference of the actuator housing 34.2. Before the chain holder 42.2 is clamped, the chain holder 42.2 can be displaced on the circumference of the cylindrical actuator housing 34.2 and can therefore be adjusted in its final position. The position of the chain holder 42.2 on the actuator housing 34.2 is fixed by the clamping along the length of the actuator housing 34.2. A compartment 44.2 is provided in the upper part or section of the block-like or cuboid chain holder 42.2, which opens outwards via the corner of the chain holder 42.2 shown or is accessible from the outside. A first gear 45.2 or pinion is rotatably arranged in the compartment around a shaft 46.2 or with the shaft 46.2. The chain 41.2 is held at one of its ends on the chain holder 42.2 with a chain attachment 47.2.

A carrier 35.2 is connected to the cylinder 37.2 and protrudes from the actuator housing 34.2 through a slot 51.2. The hook-shaped driver 15.2 of FIG. 7 is used here as the carrier 35.2 in FIG. 8. A cylindrical gear housing 48.2 is fastened to the carrier 35.2, in which a further gear 49.2 is rotatably arranged or supported. In the wall of the gear housing 48.2 are spaced apart of the two slots 48.12 through which the chain 41.2 passes.

The chain 41.2 extends from the chain attachment 47.2 on the chain holder 42.2 in the direction of the gear housing 48.2, which is connected to the carrier part 35.2. The chain 41.2 is placed around the gear 49.2 and extends through one of the slots 48.12 into the gear housing 48.2 and out of the gear housing 48.2 through the other of the slots 48.12 and is thus deflected by the gear 49.2 through 180 °. The chain 41.2 extends from the gear housing 48.2 in the direction of the chain holder 42.2 and enters the compartment 44.2, passes the gear 45.2, which engages in the chain links of the chain 41.2, and leaves the compartment 44.2 after being deflected by 90 degrees. Coming from compartment 44.2, the chain extends to the assigned pedal or pedal lever on which the chain with its end link, e.g. With . a clamp is attached.

If the pressure cylinder 31.2 is pressurized against the force of the spring 36.2, the cylinder 37.2 is moved in the direction of the actuator holder 39.2. The carrier 35.2 with the gear housing 48.2 then also moves with the cylinder 37.2, as a result of which the chain 41.2 is pulled away from the chain holder 42.2 in the direction of the actuator holder 39.2. This movement is implemented via the gear 49.2 on the attachment of the chain 41.2 to the pedal, whereby the pedal is deflected or actuated by the chain pull.

If the pressure in the pressure cylinder 31.2 decreases, the cylinder 37.2 together with the carrier 35.2 and the gear housing 48.2 is pushed back by the spring 36.2 towards the chain holder 42.2, so that the chain length between the chain holder 42.2 and the gear 49.2 or the gear wheel housing 48.2 is shortened and thus the actuation of the coupled pedal is withdrawn.

Due to the 180 ° deflection of the chain 41.2 by the gear 49.2, a stroke of the pressure cylinder 31.2 or the stroke of the cylinder 37.2 in the actuator housing 34.2 and the carrier 35.2 with the gear housing 48.2 in a double the stroke of the chain portion of the chain 41.2 between the Chain bracket 42.2 and the pedal implemented, whereby large pedal deflections or strokes can be performed with the actuator 30.2.

6 shows a pedal unit 80.2 arranged on the passenger side in accordance with a preferred embodiment of the present invention.

The pedal unit 80.2 has an anti-gas pedal 99.2 and an anti-gas pedal hydraulic device, the two hydraulic pressure cylinders 69.2, 68.2 arranged at a distance from one another and parallel to one another as pressure cylinder devices with an identical structure, pressure piston rods 70.2 and 71.2 with an identical structure, compression springs 68.2 and 67.2 with an identical structure, guide rods 66.2 and 65.2 with an identical structure, a hydraulic block 64.2, a slider 63.2 or slide which is mounted to move back and forth on the guide rods 66.2 and 65.2, which is illustrated in FIG. 6 by the double arrow shown, an end block 62.2 in which a pedal lever 60.2 is pivotally articulated, and a support lever 61.2, which is articulated on the pedal lever 60.2 and on the slider 63.2 and thus connects the slider 63.2 to the pedal lever 60.2, so that a movement of a pedal lever 60.2 onto the slider 63.2 via the Support lever 61.2 can be transmitted. The pedal lever 60.2 engages at one end in a recess in the end block 62.2, in which a pin runs, about the longitudinal axis of which the pedal lever 60.2 can be pivoted or rotated. The recess in the end block 62.2 is dimensionally designed such that there is sufficient freedom of movement of the end of the pedal lever 60.2 mounted in the end block 62.2. At the opposite end of the pedal lever 60.2, a flat pedal disk of the anti-gas pedal 99.2 is attached, which enables foot actuation by the passenger or driving school teacher.

The support lever 61.2 is articulated to the pedal lever 60.2 such that a movement of the pedal lever 60.2 is converted to a movement of the support lever 61.2. The other end of the support lever 61.2 engages in a slot-shaped recess 63.12 in the slider 63.2 and is in turn rotatably or pivotably mounted in this recess around a cross pin, the cross pin of the slide 63.2 for mounting the support lever 61.2 parallel to the bearing pin in the end block 62.2 is aligned for the storage of the pedal lever 60.2. In addition, the cross pin for the mounting of the support lever 61.2 in the slider 63.2 and also the mounting pin for the mounting of the pedal lever 60.2 in the end block 62.2 are aligned perpendicular to a direction of movement of the slider 63.2 on the guide rails 66.2 and 67.2.

The block-like slider 63.2 is mounted on the guide rail 66.2 with a linear bearing 72.2 and is movably mounted on the guide rod 65.2 with a second linear bearing 74.2. The two linear bearings 72.2 and 74.2 are fitted and housed in through bores or channels with a circular cross-section of the slider 63.2 and enable the slider 63.2 to be linearly supported on the guide rods 66.2 and 65.2. The slider 63.2 is made of polyethylene, for example (Type Simona PE-HWST according to ISO 10285). For example, a linear ball bearing with raceway plates (type SKF LBBR12-2LS) is used as the linear bearing 72.2 or 74.2.

In the slider 63.2, pressure piston rods 70.2 and 71.2 extending parallel to one another are also fastened with their ends free of pressure pistons. Movement or displacement of the slider 63.2 on the guide rods 66.2 and 65.2 is thus implemented directly on the pressure piston rods 70.2 and 71.2.

The pressure piston rods 70.2 and 71.2 engage in the pressure cylinder 69.2 and 68.2, the pressure piston rod 70.2 protruding into the pressure cylinder 69.2 and the pressure piston rod 71.2 protruding into the pressure cylinder 68.2. At the ends of the pressure piston rods 70.2 and 71.2 located in the pressure cylinders 69.2 and 68.2 there are pressure pistons which are movably sealed in the corresponding pressure cylinders 69.2 and 68.2. A movement of the pressure piston rods 70.2 or 71.2 is converted onto the corresponding pressure piston and thus also exerted on the liquid column in the pressure cylinders.

The two pressure cylinders 69.2 and 68.2 extend parallel to one another and are in the hydraulic block 64.2 e.g. attached by appropriate screw connections. The outputs of the two pressure cylinders 68.2 and 69.2 are combined via a channel 64.12 in the hydraulic block 64.2 to an access of the hydraulic block 64.2 provided with a hollow screw 64.22.

The guide rods 66.2 and 65.2, which extend parallel to one another, are firmly connected at one end to the hydraulic block 64.2, for example by means of corresponding screw connections, and extend further through the slider 63.2. borrowed through the linear bearings 72.2 and 74.2, and extend further to the end block 62.2, with which they are firmly connected, again for example by screw connections. A compression spring 68.2 is installed between the slider 63.2 and the hydraulic block 64.2 and winds helically around the guide rod 66.2. The compression spring 68.2 or coil spring is attached or screwed to the hydraulic block 64.2 at one end, while the other end of the compression spring 68.2 is screwed to the slider. The compressive force of the compression spring 68.2 moves the slider 63.2 away from the hydraulic block 64.2 in the direction of the end block 62.2 when there is no counterforce from the pedal lever 60.2. Another compression spring 67.2 or helical spring is arranged on the guide rod 65.2 between the slider 63.2 and the hydraulic block 64.2 and fastened to it like the compression spring 68.2. The pressure force of the compression spring 67.2 also tends to move the slider 63.2 away from the hydraulic block 64.2 in the direction of the end block 62.2.

A spacer sleeve 73.2 is pushed onto the guide rod 66.2 between the slider 63.2 and the end block 62.2. An identical spacer sleeve 73.2 is also pushed onto the guide rod 65.2 between the slider 63.2 and the end block 62.2. The two spacer sleeves 73.2 are constructed identically to one another and have the purpose of restricting the movement of the slider 63.2 towards the end block 62.2, that is to say that the slider 63.2 strikes the spacer sleeves 73.2 when only the compressive forces of the two springs 68.2 and 67.2 are without Counteracting pedal actuation. The slider 63.2 is then in the position shown in FIG. 6.

The fictitious axes of symmetry of the pressure cylinder 69.2 and the pressure piston rod 70.2 coincide. The fictitious axes of the pressure cylinder and the pressure rod 71.2 also coincide. The axes of the two pressure cylinders 69.2 and 68.2 are aligned exactly parallel to each other. In addition, the axes of the guide rods 66.2 and 65.2 are aligned parallel to one another and lie together with the axes of the pressure cylinders 69.2 and 68.2 in a common plane. The support lever 61.2 is mounted centrally in the slider 63.2, so that forces occurring when the pedal is actuated are evenly distributed over the two cylinder pistons 70.2 and 71.2 via the slider 63.2. The pedal lever 60.2 is also mounted centrally between the guide rods 66.2 and 65.2 on the end block 62.2.

The pedal unit 80.2 is preferably fastened on a plate 100.2, which in turn rests on the passenger side of the vehicle on the floor in the passenger area and can preferably be fastened there with a Velcro connection. The pedal unit 80.2 can therefore be easily assembled and disassembled due to the Velcro connection required alone. The pedal unit 80.2 or its mounting plate 100.2 can also be screwed to the floor. The Velcro connection is sufficient because the force applied to the pedal lever 60.2 when the pedal is actuated is transmitted to the slider 63.2 via the pedal lever 60.2 and the support lever 61.2 in such a way that a linear force component, i.e. a force component only in the direction of movement of the slider 63.2, and furthermore one Force component arises which acts perpendicular to the direction of movement of the slider 63.2, i.e. towards the vehicle floor, whereby the pedal unit 80.2 is pressed vertically onto the vehicle floor when the pedal is actuated and therefore no tilting forces can act on the pedal unit 80.2 when the pedal is actuated.

A preferred embodiment of the double pedal device of the invention for a driving school vehicle with an automatic transmission is shown by way of example in FIGS. 9 and 10, with the pedal set 90.6 on the driver side of the motor vehicle in FIG. 9 and in Fig. 10 the second pedal set 80.6 is shown on the passenger side, ie on the driver's side.

The first pedal set on the driver side comprises an accelerator pedal 95.2, a brake pedal 94.2, an anti-gas actuator 10.12 according to FIG. 7, the driver 15.12 of which engages with a pedal lever 95.12 of the accelerator pedal 95.2, a further actuator 30.2, which is shown in more detail in FIG. 8 whose chain 41.2 at its end on a pedal lever 94.12 of the pedal 94.2, for example is fastened with a clamp, and a gas actuator 10.22, which has the same structure as the anti-gas actuator 10.12 and its driver 15.22 with the pedal lever 95.12 of the accelerator pedal 95.2 in engagement.

A pressure cylinder 11.12 of the anti-gas actuator 10.12 is connected to the hydraulic pressure line 92.2 through a hollow screw 13.12, which closes the pressure cylinder 11.12. The pressure cylinder 31.2 of the actuator 30.2 is connected to a pressure line 91.2 in a fluid-continuous manner via the hollow screw 33.2. A pressure cylinder 11.22 of the gas actuator 10.22 is connected to a pressure line 90.2 in a fluid-continuous manner.

The gas actuator 10.22 causes a gas increase and the anti-gas actuator 10.12 causes a gas withdrawal. The driver's accelerator pedal 95.2 can be moved between a zero throttle position in which no gas is applied and a full throttle position in which full throttle is applied. The anti-gas actuator 10.12 moves the driver-side accelerator 95.2 in the direction from the full throttle position to the zero throttle position when the passenger-side anti-gas pedal 99.2 is actuated, and the gas actuator 10.22 moves the driver-side accelerator pedal 95.2 in the direction from the zero gas position to the full throttle position when a passenger-side accelerator pedal 97.2 is operated. According to FIG. 10, the second pedal set 80.6 on the passenger side has three pedals, namely the gas pedal 97.2, the brake pedal 98.2 and the anti-gas pedal 99.2. The second pedal set has a pedal unit 80.2 with the anti-gas pedal 99.2, which is shown in more detail in FIG. 6, a further pedal unit 80.12 with the brake pedal 98.2, which corresponds to the pedal unit 80.2 described in FIG. 6, and a third pedal unit 81.2 with the accelerator pedal 97.2 which, in contrast to the pedal units 80.2 and 80.12, only has a single pressure cylinder with pressure piston rod, a single guide rod with compression spring, a correspondingly adapted glider, hydraulic block and end block with support lever connection to the accelerator pedal 97.2. Instead of the pedal unit 80.2, a further pedal unit 81.2 or vice versa could also be used, but the change in the pedal function must be taken into account.

The hydraulic block 64.2 of the pedal unit 80.2 is continuously connected to the pressure line 92.2 via the hollow screw 64.22, which has a screw-in connector. The hydraulic block of the pedal unit 80.12 is connected to the pressure line 91.2 via its banjo bolt. The hydraulic block of the pedal unit 81.2 is also connected to the pressure line 90.2 via a banjo bolt.

The hydraulic devices used, that is to say the passenger-side pressure cylinder devices shown in FIG. 10, each having a pressure cylinder with a pressure piston rod, the pressure cylinder devices of the actuators 10.12, 10.22 and 30.2 shown in FIG. 9, which also each have a pressure cylinder and an associated pressure piston rod , the flexible pressure lines 90.2, 91.2 and 92.2 of a pressure line device and the hydraulic blocks 64.2 on the passenger side are connected with a hydraulic flow liquid filled. Hydraulic oil, fork oil or white oil can be used as the hydraulic fluid. A hydraulic fluid with a viscosity number 1 is preferably used in order to avoid delays in the reaction of the hydraulic fluid column to pressure changes. A preferred white oil is of the type Renolin MR1VG5 and has a viscosity number of 1. The pressure lines are, for example, microfluidic hose lines made of synthetic synthetic fiber (eg type EMMKT8 PN500 PB 800 DN 2).

When the anti-gas pedal 99.2 on the driving instructor side is actuated, the slider 63.2 of the pedal unit 80.2 is moved in the direction of the hydraulic block 64.2, the piston rods 70.2 and 71.2 exerting pressure on the liquid column in the pressure cylinders 69.2 and 68.2. This pressure is transferred from the hydraulic block 64.2 into the pressure line 92.2 within the liquid column and finally coupled into the pressure cylinder 11.12 of the anti-gas actuator 10.12 via the hollow screw 13.12. The associated pressure piston rod then moves the cylinder with driver 15.12. Since the driver 15.12 is in engagement with the pedal lever 95.12 of the deflected, driver-side accelerator pedal 95.2, the accelerator pedal 95.2 is moved in the direction of its zero throttle position with the gas being withdrawn. If the pressure on the antigas pedal 99.2 is withdrawn or given up, the spring 16.12 of the antigas actuator 10.12 pushes back the cylinder with driver 15.12 and thus also the pressure piston rod. The slider 63.2 of the pedal unit 80.2 is moved back to its starting position by the spring force of the two springs 67.2 and 68.2 but also by the change or the suction pressure in the pressure cylinders, i.e. in the stop position on the sleeves 73.2.

If the brake pedal 98.2 on the passenger side is actuated, the pressure on the liquid column is planted via the two the pressure cylinder and the hydraulic block of the pedal unit 81.12 onto the pressure line 91.2 and from there into the pressure cylinder 31.2 of the actuator 30.2. The carrier 35.2 with gear housing 48.2 is consequently displaced, as a result of which the chain section between the chain holder 42.2 and the pedal lever 94.12 is shortened and the pedal 94.2 is deflected. If the actuation of the pedal 98.2 on the passenger side is subsequently withdrawn or abandoned, the pedal 94.2 is returned to its rest position by its pedal return spring (not shown), as a result of which tension is exerted on the chain 41.2, which is connected to the pedal lever 94.12 of the brake pedal 94.2 and the carrier 35.2 together with the gear housing 48.2 is now retracted in the direction of the chain holder 42.2. The resulting pressure on the liquid column is returned via the pressure cylinder of the actuator 30.2 and the pressure line 91.2 to the passenger side, namely to the hydraulic block of the pedal unit 80.12, so that the pressure cylinders of the pedal unit 80.12 together with the pressure springs of the pedal unit 80.12 move the slider to its initial position move back.

When the accelerator pedal 97.2 on the driving instructor side is actuated, the slider of the pedal unit 81.2 is displaced in the direction of the associated hydraulic block, the piston rod of the single pressure cylinder device of the pedal unit 81.2 exerting pressure on the liquid column in the associated pressure cylinder 81.22. This pressure is transferred from the hydraulic block 81.32 into the pressure line 90.2 within the liquid column and finally coupled into the pressure cylinder 11.22 of the gas actuator 10.22 via the hollow screw 13.22. The pressure piston rod of the gas actuator 10.22 then moves the cylinder with driver 15.22. Since the driver 15.22 is in engagement with the pedal lever 95.12 of the driver's accelerator pedal 95.2, the accelerator pedal 95.2 is ter gas increase in the direction of its full throttle position. If the pressure on the accelerator pedal 97.2 on the passenger side is released or released, the spring of the gas actuator 10.22 pushes the cylinder with driver 15.22 and thus also the pressure piston rod back again. The slider of the pedal unit 81.2 is moved back to its starting position by the spring force of the single spring of the pedal unit 81.2 but also by the change or the suction pressure in the individual pressure cylinders of the pedal unit 81.2.

11 and 12 show an example of a preferred embodiment of the driving instructor stand of the invention for use in a driving school vehicle. The driving instructor station has a driving instructor seat 1.5, the driving instructor-side pedal device 80.5 of FIG. 5 or the driving instructor-side pedal device 80.6 of FIG. 10 and a display device 15.5. The driving instructor stand is installed, for example, in the driver's compartment 10.5 with the dashboard 14.5 of a bus that serves as a driving school vehicle.

The driving instructor seat 1.5 has a seat part 31.5, a backrest part 2.5, a headrest 6.5, a gas spring 5.5 or air spring which is connected at one end to the seat part 31.5 and at the other end to a base plate 3.5. The backrest part 2.5 can be pivoted about an axis 8.5 in order to be able to adjust the inclination of the backrest part 2.5 with respect to a seat 7.5 of the seat part 31.5. By actuating a valve of the gas spring 5.5 using a lever 32.5, the height of the seat surface 7.5 above the base plate 3.5 can be adjusted. The base plate 3.5 is fastened to a base group 9.5 of the bus by means of a screw connection 4.5. The use of a screw connection enables the driver's seat 1.5 and thus the entire driving instructor's seat to be quickly installed in the bus and also its fast and easy fold expansion, which enables a quick conversion of the vehicle into a driving school vehicle and vice versa. As can be seen from FIG. 11, the seat surface 7.5 of the driving instructor seat 1.5 is at a higher height level than the seat surface of the driver's seat 11.5, shown schematically in dashed lines. The driving instructor seat 1.5 or the driver's station can be located in a central area between the driver seat 11.5 and a passenger seat, not shown, wherein this central area can also extend towards the rear of the vehicle, as can be seen from FIG. 11.

The pedal device 80.5 (or 80.6) on the driving instructor side is fastened to the seat part 31.5 of the driving instructor seat 1.5 by means of a bracket 12.5. The bracket 12.5 has a seat plate 30.5, an inclined part 33.5 and a plate 34.5, which is aligned parallel to the floor plate 3.5 or the floor assembly 9.5 of the vehicle. The seat plate 30.5 of the bracket 12.5 is fastened to the seat part 31.5 by a screw connection. The inclined part 33.5 sloping downward towards the floor group 9.5 connects the seat plate 30.5 to the plate 34.5 in one piece. Attached to the longitudinal edges of the plate 34.5 are two guides 17.5 and 18.5 aligned parallel to one another, which provide continuous receptacles for an edge region of the pedal device 80.5 (or 80.6) which can be inserted into the guides 17.5 and 18.5 in the direction of the arrow 19.5. The guides 17.5 and 18.5 each have holes 38.5 or corresponding elongated holes, which are lined up at the top, with the aid of which the pedal device 80.5 (or 80.6) on the driver's side can be locked and fastened in the guides by means of a screw connection or clamping connection. By moving or moving the pedal device 80.5 (or 80.6) within the guides 17.5 and 18.5, a distance A5 between the driving instructor seat 1.5 and the pedal device 80.5 (or 80.6) can be set. On the plate 34.5 of the holder 12.5, a display holder 16.5 is fastened at an angle to the end of which the display device 15.5 is attached. For example, an LCD or a monitor can be used as the display device 15.5. The display device 15.5 is electrically coupled to a video camera 50.5 via a coupling device 13.5 and a plug 42.5 on the dashboard 14.5. The video camera 50.5 is attached to a left wing mirror 40.5 of the bus and thus captures the left-hand surrounding area of the bus. The image captured by the video camera 50.5 is displayed to the driving instructor on the display device 15.5, as a result of which, for example, the driver can recognize a vehicle in the "blind spot".

5 has the pedal units 80, 80.1 and 81 with the corresponding pedals 99, 98 and 97. The pedal device 80.5 is via the pressure lines 90, 91, 92 with the supplementary driver device pedal device 90.5 of FIG Double pedal device for priority control of the driver-side pedal device 90.5 coupled.

Similarly, the driver device-side pedal device 80.6 from FIG. 10 has the pedal units 80.2, 80.12 and 81.2 with the corresponding pedals 99.2, 98.2 and 97.2. The pedal device 80.6 is coupled via the pressure lines 90.2, 91.2, 92.2 to the supplementary, driver-side pedal device 90.6 of FIG. 9 of the double pedal device with antigas for the priority control of the driver-side pedal device 90.6.

FIGS. 13, 14 and 15 show, by way of example, a further preferred embodiment of the driving instructor stand of the invention for use in a driving school vehicle. The driving instructor's booth has a driving instructor seat 30.6, a control unit 20.6, a driving instructor-side, passenger-side pedal device 80.5 according to FIG. 5 (or 80.6 according to FIG. 10) and a holder 1.6 to which the pedal device 80.5 (or 80.6) is fastened. The driving instructor stand is installed, for example, in the driver's compartment 40.6 with a dashboard 41.6 of a bus, which serves as a driving school vehicle. As usual, the driver's compartment 40.6 has a floor 42.6 and a flat inner lining 43.6 which extends perpendicular to the floor 42.6.

The driving instructor seat 30.6 has, among other things, a seat part 33.6 with a seat, a backrest part 31.6 and a right-hand armrest 32.6 and is fastened to a base plate or the base 42.6 of the driving school vehicle. The driving instructor seat 30.6 or the driving instructor stand can be located in a central area between a driver seat and a passenger seat, not shown.

The control unit 20.6 of the driving instructor station of the invention is preferably designed in the form of a control stick 20.16 or a joystick and has a handle 21.6, an angle part 24.6, a tubular fastening part 25.6, a control knob 22.6 and a coupling device 23.6 for coupling the control unit 20.6 to the electrical system of the driving school vehicle.

The fastening part 25.6 is rigidly fastened to the driving instructor seat 30.6. The angle part 24.6 of the control unit 20.6 has a horizontally extending pipe part 24.16 and a further pipe part 24.26 extending vertically or perpendicularly to the pipe part 24.16. The free end of the tubular part 24.16 is mounted in the fastening part 25.6 so as to be rotatable about its axis and movable in and out of the fastening part 25.6. The approximately tubular or cylindrical handle 21.6 of the Joystick 20.16 is rotatably supported at one end in the tubular part 24.26 about its axis and carries the joystick 22.6 at the other end. The control knob 22.6 is provided with various switches 26.6 or also electrical actuating devices such as, for example, regulators, which serve for the electrical switching of functions of the electrical system of the driving school vehicle. The functions which can be switched via the switches 26.6 are, for example, the functions of the signal system, such as turn signals and horn, the wiping and rinsing system, such as, for example, windshield wipers, and the headlight system, such as low beam, high beam of the driving school vehicle. The driving instructor can also control driving functions such as brakes, clutches, gas and even steering and switching operation via electrical actuators on the joystick or on the control unit if the electrical system of the driving school vehicle has corresponding electrical actuators and systems such as an electromotive control of gas operation, the clutch, braking operation, etc. The switches 26.6 and electrical actuation devices of the control unit 20.6 are connected or coupled to the electrical system of the driving school vehicle via the coupling device 23.6. For example, a cable can be used as the coupling device 23.6, as shown in FIG. 15, which extends in the interior of the tubular parts 25.6, 24.16, 24.26, 21.6 into the control knob 22.6 and there with the switches 26.6, such as, for example, pushbuttons and rocker switches and actuators are either directly connected or connected via interface electronics. The cable is then coupled, for example via a plug-in connection, to a corresponding connector on the dashboard 41.6 of the driving school vehicle, the connector of the dashboard 41.6 in turn being electrically coupled to the electrical system of the driving school vehicle in a corresponding manner such that the functions of the electrical system can be controlled as intended from the control unit 20.6. The coupling device 23.6 can but can also be designed, for example, as a telemetry system with corresponding transmitters and receivers for, for example, an electromagnetic, optical, for example infrared, or ultrasonic coupling of the control unit 20.6 to the electrical system of the driving school vehicle.

The control unit 20.6 is generally preferably attached to the driving instructor seat 30.6, e.g. through the fastening part 25.6. Furthermore, the control unit 20.6 is arranged in the driving instructor's booth in such a way that the driving instructor can operate it comfortably and ergonomically. In the embodiment specifically shown, the control stick 20.16 of the control unit 20.6 is located next to the free end of the right armrest 32.6 of the driving instructor seat 30.6 in such a way that the driving instructor can easily grip the handle 21.6 of the control stick 20.16 with his hand and in particular with that, while supporting his right forearm Thumb can easily reach switch 26.6. The handle 21.6 thus has a length which corresponds approximately to the width of the hand. The switches 26.6 on the control knob 22.6 are then a maximum of about a thumb length from the end of the handle 21.6 in order to enable a comfortable and safe actuation of the switches 26.6.

A display device (not shown) can also be attached to the control unit 20.6. An LCD, for example, can be used as the display device. The display device is preferably electrically coupled to, for example, a video camera via a further coupling device. The video camera can be attached to a left wing mirror of the bus and thus captures the left-hand surrounding area of the bus. The image captured by the video camera is displayed to the driving instructor on the display device, as a result of which, for example, a vehicle can be recognized by the driving instructor in the "blind spot". The display device can on the top of the control knob 22.6 of the control stick 20.16 of the control unit 20.6, for example by means of a flexible tube, in order to be able to adjust the position of the display device.

The pedal device 80.5 (or 80.6) on the driver's side is attached to the vertical interior lining 43.6 or the vertical body section of the driving school vehicle in the driver's cell 40.6 by means of the holder 1.6 (cf. in particular FIG. 15).

The holder 1.6 essentially has a frame with two vertical bars 6.6 and 6.16 extending parallel to one another at a distance, a base plate 2.6 on which the vertical bars 6.6 and 6.16 are perpendicular, and a protruding handle section 12.6 projecting into the space in the driver's compartment 40.6. The vertical bars 6.6 and 6.16 extend between the base plate 2.6 and the handle section 12.6. Furthermore, the holder 1.6 has a footrest 7.6 and a fastening frame 10.6, 11.6 for fastening the pedal device 80.5 (or 80.6) to the holder 1.6.

The bracket 1.6 is screwed to the base plate 2.6 on the floor 42.6 of the driving school vehicle. A crosspiece 4.6 extends horizontally between the vertical bars 6.6 and 6.16 and is screwed to the inner lining 43.6 of the driving school vehicle.

The handle section 12.6 has a cross member 3.6, a left-hand curved tube part 13.6 and a right-hand curved tube part 14.6, which connect the cross member 3.6 to the vertical member 6.6 and the vertical member 6.16 in one piece. The curved tube parts 13.6 and 14.6 each protrude from the vertical spars 6.6 and 6.16 in an approximately arcuate bulge on the driver's side and on the side of the passenger door. The footrest 7.6 has a horizontally extending support tube 7.16, which extends at right angles across the vertical bars 6.6 and 6.16 of the same length, and two support tubes 8.6 and 9.6 of equal length and extending parallel to one another. The support tube 8.6 connects the support tube 7.16 in one piece to the vertical beam 6.6, while the support tube 9.6 connects the support tube 7.16 in one piece to the other vertical beam 6.6.

The mounting frame 10.6, 11.6 has two, mutually parallel side parts 10.6, one on the side of the vertical bar 6.16, the other (not visible) on the side of the vertical bar 6, on and between which the pedal device 80.5 (or 80.6), for example by Screw connection is fixed, and a crosspiece 11.6, which extends between the vertical bars 6.6 and 6.16 slightly below the support tubes 8.6 and 9.6. The side part 10.6 shown is inclined relative to the plane of the vertical bars 6.6 and 6.16 towards the driving instructor seat 30.6 and forms an angle with the vertical bar 6.16, which e.g. Can be 15 °. Consequently, the side part, not shown, is also inclined towards the driving instructor seat 30.6 with respect to the plane of the vertical bars 6.6 and 6.16 and includes the same angle with the vertical bar 6.6, e.g. can also be 15 °. The angle vertex of the angle is located on the base plate 2.6, while the angle opening is at the height of the cross part 11.6, on which the side parts 12.6 are welded.

As shown in FIG. 15, in which the pedals of the pedal device 80.5 are shown not actuated, the pedals are located in the side parts 10.6 of the pedal device 80.5 (or 80.6) in the space between the support tube 7.16 of the footrest 7.6 and the base plate 2.6 the bracket 1.6 or the floor 42.6 of the driver's compartment 40.6, or otherwise pressed, the footrest 7.6 or its support tube 7.16 is arranged spatially above the pedals. More precisely, the footrest 7.6 or the cross tube 7.16 extends in a plane parallel to the plane of the vertical bars 6.6, 6.16 and an assumed axis through the pedals 99, 98 and 97 extends in a plane which is in turn parallel to the vertical plane of the support tube 7.16 , The vertical plane of the support tube 7.16 is at a distance from the vertical, parallel plane of the pedals. This horizontal distance is, for example, 5 cm to 15 cm and enables the pedals to be reached freely. The footrest 7.6 thus extends set back in the area between the vertical bars 6.6, 6.16 and this vertical plane of the pedals. If you place a horizontal plane through the pedals 99, 98, 97 and a parallel horizontal plane through the support tube 7.16, both of which are perpendicular to the vertical plane of the vertical bars 6.6 and 6.16, there is a vertical distance between the two horizontal planes, the for example, can be 5 cm to 20 cm. This means that the footrest 7.6 or the support tube 7.16 is arranged at this distance in the area above the pedals.

It has been found that the arrangement of the footrest 7.6 enables the driving instructor to actuate the pedals very quickly by the driving instructor. The driving instructor, for example, supported the left foot on the footrest 7.6. If the driving instructor now has to intervene in the driving action in order to correct the pupil, the foot only needs to be moved down onto the pedals, for example the pedal 99, in order to be able to actuate the pedal. One can also simply speak of a "dropping" of the foot, which surprisingly leads to a very fast pedal actuation reaction and thus to increased safety when driving the school. 13, 14 and 15 is shown in greater detail in FIG. 5, which is composed of the pedal units 80, 80.1 and 81 with the corresponding pedals 99, 98 and 97 for clutch, brake and gas. The pedal device 80.5 is via the pressure lines 90, 91, 92 with the supplementary, driver-side pedal device 90.5 from FIG. 4 of the double pedal device for the primary control of the driver-side pedal device

90.5 coupled.

The pedal lever 60 and also the support lever 61 of the pedal linkage are surrounded by a closed, folded, flexible sleeve 601 (see Fig. 15) which is made of rubber, e.g. Natural rubber. The sleeve 601 protects the pedal device 80.5 from contamination, e.g. Splash. The pedal lever and support lever for the pedal 98 is also provided with an associated, folded and flexible sleeve 602.

If the pedal device 80.6 from FIG. 10 with the pedal units 80.2, 80.12 and 81.2 and the corresponding pedals 99.2, 98.2 and 97.2 is used in the driving instructor station according to FIGS. 13, 24 and 15, the pedal device is used

80.6 via the pressure lines 90.2, 91.2, 92.2 to the supplementary, driver-side pedal device 90.6 of FIG. 9 of the double-pedal device with antigas for priority control of the driver-side pedal device 90.6.
