Description

The invention relates to a manually operable control lever element for driving movable elements of a vehicle, according to the preamble of claim 1 and a vehicle according to the preamble of claim 13.

Vehicles equipped with multiple movable elements in terms of functional components or assemblies conventionally have controls for driving these movable elements. Examples of such vehicles are about a forklift or a tractor. As another example, here is an excavator called excavating machine, as he is known to be used for excavation work. This excavator has (see also 2a and 2 B ), for example, four movable elements: a vehicle cabin which is pivotable to the left and to the right, a first boom pivotally mounted on the vehicle cabin, a second boom arm pivotally mounted on the first boom, and finally an excavator bucket pivotally mounted on the second boom arm. The latter three elements are preferably arranged pivotable upwards and downwards. So there are two differently directed movements per element possible, so a total of eight.

To control movable elements or their movement functions so-called joysticks or sticks are known from the prior art, which resemble a gearshift lever from the car and arranged by the user of the vehicle (driver), such as an excavator (excavator operator) manually operated within the vehicle cabin are. These are arranged pivotable from a starting position to the left and to the right and to the front and to the rear. If the excavator operator can operate a joystick with both the left hand and the right hand, then a total of eight different start or input movements can be realized, which are subsequently explained by means of a suitable control device, which will be explained in more detail below eight output movements of the excavator are transferable. The Standard ISO 10968 deals, for example, with the assignment of the input movements or basic functions of the joystick to the output movements or machine functions of the excavator. This standard is also the illustrations according to 2a and 2 B taken.

The problem with conventional joysticks is that the movement that the operator, such as an excavator operator, must perform to perform the basic functions of the joystick is always exerted out of the shoulder as well. This can lead to overuse, fatigue, discomfort and pain especially in the shoulder of the driver for several hours, as they are common on construction sites, field work or the like.

Object of the present invention is thus to further develop the conventional control devices so that thus a largely fatigue and pain-free work is possible.

This object is achieved according to the features of claim 1 and the features of claim 13.

An essential point of the invention is that a manually operable control lever element for driving movable elements of a vehicle, preferably an excavating machine is arranged, comprising a in a longitudinal direction and / or in a width direction of a vehicle cabin of the vehicle by means of a first end pivotally arranged control rod element, with an outer ring element rigidly connected to a second end of the control rod element and an inner ring element rotatably disposed within the outer ring element, at least one first signal being able to be generated by means of rotational movements of the inner ring element by means of at least one first detection element in operative contact with the inner ring element.

The first signal is preferably an electrical signal and at the same time an input signal for a control device or control unit described in more detail below.

In the case of the manual control lever element according to the invention, at least one first signal can thus be generated by means of a rotation of the inner ring element relative to the outer ring element by the first detection element, the first detection element preferably being able to distinguish between the clockwise rotation and the counterclockwise rotation, so that overall two first signals can be generated.

This rotation can be carried out extremely ergonomically by hand out of the wrist of the vehicle driver, for example a digger operator, so that the shoulder is completely relieved here and the disadvantages described above are overcome. In this case, the forearm of the driver can be conveniently placed on an armrest and thus supported, whereby the elbow and the wrist are secured in position. As a result, the movement to be performed can be carried out very accurately.

For the purposes of the invention, a distinction is made between the terms pivoting and (twisting) insofar as pivoting represents a rotational movement about an axis which lies either outside or at one end of the pivoted body. In contrast, a rotation is a rotational movement about an axis which lies substantially in the geometric center or in the center of the pivoted body.

At least one second signal and / or by means of a third detection element in operative contact with the outer ring element by means of pivoting movements of the outer ring element in the width direction of the vehicle cabin is advantageously at least one by means of a second detection element in operative contact with the outer ring element in the longitudinal direction of the vehicle cabin third signal can be generated.

It is understood that a pivoting of the outer ring member also always represents a pivoting of the control rod member, since both are rigidly interconnected as described above. In this case, the outer ring element does not have to be completely closed, but can be designed to extend over a semicircle, for example. It only has to ensure a mechanical guidance of the inner ring element.

The outer ring element thus performs a rotational movement about an axis which is arranged at the first end of the control rod element, that is to say outside the outer ring element, that is, which represents a pivoting movement. In this case, a reference axis on the one hand parallel to the longitudinal extent of the control rod element or the assembly, which consists of control rod member and outer ring member, arranged and extends through the axis of rotation of the pivoting movement and perpendicular to this. This reference axis is hereinafter referred to as the control rod central axis.

To increase the ease of use, it is advantageous if the outer ring element is arranged extending in a basic position in the width direction and height direction or longitudinal direction and height direction of the vehicle cabin. The basic position is defined, for example, in that the control rod central axis is arranged vertically, that is to say without pivoting, with respect to a plane which is formed by the longitudinal and the width direction of the vehicle cabin. This makes it possible for the driver to comfortably grasp the outer ring element and to operate it within the meaning of the invention. It thus corresponds to the direction of extension of the outer ring member at least one of the two pivoting directions. It is conceivable that the outer ring element can be converted from the first position to a second position relative to the control rod element, the first extending in the first position in the longitudinal direction and in the second position in the width direction of the vehicle cabin.

Furthermore, it is possible that the position of the axes of rotation is adjustable in height, for example, by the part of the vehicle cab, on which the control rod is mounted, can be moved downwards or upwards or pivoted.

In this case, according to a preferred embodiment, it is advantageous if a handle bar element is arranged between two connection points arranged on an inner diameter of the inner ring element. As a result, the ease of use can be further increased because a comfortable grip option is formed by means of the handle bar element, which can be enclosed by hand, whereby the driver has the feeling to be directly connected to the vehicle or the machine. Preferably, the inner diameter corresponds 12 of the inner ring element has a value from a range of 15 cm to 25 cm, more preferably a value from a range of 17 cm to 23 cm, most preferably a value of 20 cm. Preferably, the diameter corresponds 13a of the handlebar element 13 a value from a range of 1.5 cm to 5 cm, more preferably a value from a range of 2.5 cm to 3.5 cm, most preferably a value of 3 cm.

It is advantageous if the first detection element, the second detection element and / or the third detection element is a magnetic, optical or mechanical sensor.

For example, the rotation of the inner ring element relative to the outer ring element can be detected by means of an arrangement of an incremental angle transmitter, a light source and a photodiode or a phototransistor. In this case, the incremental protractor is formed by a turntable, which is divided into light-transmitting and opaque sections. With the help of the light source and the phototransistor rectangular pulses are generated, which are counted and then displayed. To distinguish between right and left rotation is a second, offset channel on the turntable. The distinction is made by a special evaluation electronics.

Also conceivable would be an arrangement consisting of a type of control disk, which is provided along its first end face with different up to its second end face continuous recesses. These are arranged, for example, along a virtual circle. Behind the control disc is a first proximity sensor (depending on the material detected inductive or capacitive Embodiment) arranged so that its sensor field is covered either by the control disk or a recess thereof, so that it can generate correspondingly two different signals. In order to determine the zero position of the control disk, a further individual recess may be arranged at another position of the control disk and that outside of the virtual circle described above, behind which a second proximity sensor is arranged analogous to the first proximity sensor, which analogous to the first also from the control disk or covered by the single recess. If the latter is the case, the control disk is in the home position. The control disk can now be arranged, for example, at the first end of the control rod element, so that the course of its central axis corresponds to the course of the axis of rotation of the pivoting movement of the control rod element.

Another possibility would be to design the lower end of the control rod element in such a way that a first toothed wheel is arranged rigidly at the lower end, wherein, for example, the course of the central axis of this toothed wheel corresponds to the profile of the axis of rotation of the pivoting movement of the control rod element. A pivoting of the control rod element would therefore cause a rotation of the gear around the central axis here. For example, a second toothed wheel is engaged with this toothed wheel and now likewise rotates upon rotation of the first toothed wheel. The rotation of the second gear in a clockwise or counterclockwise direction can be detected analogously to the two options described above. This is useful if, for reasons of space, no complicated structures or sensor arrangements are possible directly at the lower end of the control rod.

As a further possibility, there is the arrangement of a second and a third gear, each fixedly mounted on a shaft, wherein on the shaft spaced from the gears each have a further rotary element, for example in the form of a hub is connected. A rotation of the second and / or third gear thus always causes a rotation of these gears associated waves. These rotary elements are now each provided with a freewheel opposite the shaft, so that a rotation of the shaft in a first direction, for example in a clockwise direction for the second gear associated with the rotary element and counterclockwise for the third gear associated rotary element, on the rotary member is transferred, but in a second direction, that is not transmitted, for example, counterclockwise for the second gear associated with the rotary element and clockwise for the third gear associated with the rotary element. The rotation of the rotating elements in a clockwise or counterclockwise direction can be detected analogously to the two options described above. The error rate in the detection of the presence of a pivoting movement of the control rod member and the detection of their direction can thus be reduced. Also, on the outer circumference of the inner ring member, for example, teeth and at the second end of the control rod member corresponding gears may be arranged.

The above-mentioned detection elements or detection units can thus serve with a suitable arrangement both for detecting the rotation of the inner ring element relative to the outer ring element and for detecting the pivoting of the control rod element or the outer ring element relative to the vehicle cabin.

For passing on and processing the signals generated by the input movements, it is also advantageous if a first, a second and / or a third transmission device are provided, which the first, the second and / or the third detection element and at least one with the first, the second and / or the third detection element connected control unit for receiving the signals from the detection elements and / or at least one controllable by means of the control unit via at least one output signal and in operative contact with one of the movable elements drive element comprise.

As an example, a signal which generates the first detection element due to a rotational movement of the inner ring element relative to the outer ring element in the counterclockwise direction, transmitted via suitable lines to a control unit as an input signal. This control unit represents, for example, a so-called PLC (programmable logic controller).

For example, a PLC has inputs, outputs, an operating system, and an interface through which the user program can be loaded. The user program defines how the outputs are to be switched depending on the inputs. The operating system, also called firmware, ensures that the user program always has the current status of all components involved. Based on this information, the user program can switch the outputs so that the machine functions as desired.

The detection units are connected to the inputs of the PLC and transmit the explained (input) signals to the control unit. The control unit now generates one each corresponding output signal which is transmitted to an actuator, for example. These actuators are connected to the outputs of the PLC and represent the drive elements, which can now perform movements associated with the respective output signals. This drive element is in turn connected, for example, with a movable element, so that a movement of the drive element always represents a movement of the movable element. In this case, both the movements of the drive element and the movements of the movable element can be rotational movements or translational movements.

For example, it is advantageous if the at least one drive element is an electric motor, a hydraulic actuator or a pneumatic actuator. For example, can be arranged as a drive element, a hydraulic or pneumatic cylinder.

Furthermore, it is conceivable that by means of the first transmission device, the rotational movements of the inner ring element in a first and / or second direction in a movement of the first or second element of the vehicle in each case a first and / or second direction are transferable.

According to a further preferred embodiment, it is again advantageous if by means of the second transmission device, the pivoting movements of the outer ring member in a first and / or second direction in a movement of the third and / or the fourth element of the vehicle in each case a first and / or second direction transferable are.

It is also conceivable that starting from the basic position, the outer ring element by means of the pivoting movement in the first direction by a maximum of 60 ° in the clockwise direction and / or by means of the pivoting movement in the second direction by a maximum of 60 ° counterclockwise pivoted. This limitation of the pivoting movement of the outer ring element or the control rod element relative to the vehicle cabin can be realized, for example, by means of rigidly arranged on the vehicle cabin and between the first and second end of the control rod element stop elements, which are formed contacting the first and second maximum position relative to the control rod member , So therefore do not allow further pivoting of the control rod member in the appropriate direction.

Analogously, it is conceivable that, starting from a basic position, the inner ring element by means of the rotational movement in the first direction by a maximum of 45 ° clockwise and / or by means of the rotational movement in the second direction by a maximum of 45 ° counterclockwise rotatable. Again, suitable stop elements may be provided on the outer ring member, which come into engagement with correspondingly formed position elements on the inner ring upon reaching the maximum positions or collide with these and so do not allow further rotation of the inner ring member in the appropriate direction.

The basic position of the inner ring element could for example be defined by a vertical or horizontal arrangement of the handle bar element. If a handle bar element is missing, the position of a reference point, which is accessible to the driver, for example, by a protrusion on the inner ring element, could define the basic position. For example, this survey could be in the basic position at the lowest point of the inner ring element (viewed in the height direction of the vehicle cab).

Both limitations are meaningful in order not to have to expect the driver ergonomically questionable movements, and to take into account the space in the vehicle cabin.

According to a further preferred embodiment, it is advantageous for the first movable element to be the vehicle cabin and / or the second movable element a first extension arm which is pivotably arranged with respect to the first movable element and / or the third movable element has a second end of the second movable element the second movable member having a first end pivotally arranged second boom arm and / or the fourth movable member is a relative to a second end of the third movable member pivotally mounted excavator bucket.

With the control lever element according to the invention thus three elements can be controlled simultaneously, as a total of six different input movements (EB) can be generated (rotational movement of the inner ring member counterclockwise (EB 1) and clockwise (EB 2), pivoting the control rod member in the longitudinal or width direction respectively counterclockwise (EB 3 and EB 5) and clockwise (EB 4 and EB 6) It is thus advantageous if a vehicle has two such control lever elements in order to be able to exercise the remaining two input movements EB 7 and EB 8.

However, it would be conceivable that a signal variant can be realized by means of the control unit and a further operating element, which is arranged, for example, in the form of a control knob on the outer ring element. Thus, according to this signal variant, for example, when the excavator for a long time with his vehicle cabin in a Direction must work aligned, so if the function of pivoting the vehicle cabin for a long time is not needed, the output signal, which was originally assigned to the drive element, which triggers the pivoting of the vehicle cab, are changed by the control unit starting at the push of a button, so that the control unit now drives another drive element, which triggers the pivoting of a further movable element, for example the first extension arm, with a corresponding output signal. This would mean that all currently required output movements would be controllable with a single control lever element.

Furthermore, it would be conceivable that the input movements can be combined with each other. For example, using the example of an excavator, the pivoting of the control rod member forward or backward could be combined with the pivoting of the control rod member to the left and to the right, respectively. It would thus be possible with appropriate occupancy of the output signals that a pivoting of the cab would be combined, for example, to the left with a retraction, ie a pivoting of the bucket upwards; and that the corresponding movement of the control lever element takes place on the one hand to the left and to the driver. The advantage would be that the movement of the joystick here corresponds to the movement of the blade or cabin and thus is intuitively executable.

The object of the invention is also achieved by a vehicle, preferably an excavating machine, comprising at least one manually operable control lever element for driving movable elements of the vehicle according to one of claims 1-12.

Advantageous embodiments will be apparent from the dependent claims.

Advantages and expediencies can be found in the following description in conjunction with the drawing.

In 1a is an inventive control lever element 1 to see which one control rod element 5 that has a first end 5a at the vehicle cabin 4 is arranged pivotably. The axis of rotation associated with this movement 27 is correspondingly perpendicular to the image plane or in this case along the vehicle longitudinal direction 9a arranged. At a second end 5b the control rod element 5 is an outer ring element 6 rigidly arranged, which is in terms of pivoting in the longitudinal direction 9a the vehicle cabin 4 in his basic position 17b located (see 1b ) and in the width direction 9b and height direction 9c the vehicle cabin 4 extends.

This corresponds to the basic position 17b the position of the control lever element 1 in which the control rod central axis 5c parallel to the height direction 9c and perpendicular to the longitudinal direction 9a the vehicle cabin 4 is arranged. In 1b are the pivoting movements 6c . 6d the control lever element 1 longitudinal 9a the vehicle cabin 4 illustrated by the arrows. The following is, however, only on the pivoting movements 6a . 6b in the width direction 9b the vehicle cabin 4 received.

Within this outer ring element 6 is an inner ring element 7 arranged, which is about a vertical axis of rotation to the image plane 28 rotatable relative to the outer ring element 6 is stored. Between two connection points 11a . 11b of the inner ring element 7 at its inner diameter 12 is a handle bar 13 arranged, which can be enclosed as shown by the hand of the excavator leader.

Indicated by means of a marked virtual axis is also the basic position 17a the control rod element 5 in terms of pivoting in the width direction 9b the vehicle cabin 4 , where this axis or basic position 17a a position of the control rod center axis 5c parallel to the height direction 9c and perpendicular to the width direction 9b the vehicle cabin 4 equivalent.

The basic position 19 of the inner ring element 7 with respect to the rotation with respect to the outer ring element 6 in a clockwise direction 18a or counterclockwise 18b corresponds in this example, an orientation of the handlebar 13 parallel to the control rod element 5 ,

Schematically marked is at the first end 5a the control rod element 5 a detection element 14c , which is suitable as explained, a pivoting of the control rod member 5 opposite the vehicle cabin 4 to capture and then depending on the direction 6a . 6b the pivoting a signal or input signal 22c1 . 22c2 to Generate, via a suitable line 24a to a control unit 20a is transmitted.

It is conceivable that the line 24c protected within the control rod element 5 runs.

From the point of view of the excavator operator is now a pivoting of the control rod element 5 around the axis of rotation 27 each opposite the vehicle cabin 4 in a first direction 6a , thus counterclockwise 18b , as well as in a second direction 6b , therefore clockwise 18a possible.

Similarly, from the point of view of the excavator operator, a rotation of the inner ring element 7 opposite the outer ring element 6 around the axis of rotation 28 in a first direction 7a , thus counterclockwise 18b , as well as in a second direction 7b , therefore clockwise 18a possible.

The control unit 20a then generates an input signal 22c1 . 22c2 respectively. 22a1 . 22a2 assigned output signal 23c1 . 23c2 respectively. 23a1 . 23a2 , which in turn has a suitable line 24b respectively. 24d to a drive element 21c respectively. 21a is passed on. This output signal 23c1 . 23c2 respectively. 23a1 . 23a2 is from the drive element 21c respectively. 21a in a movement of the whole or parts of the drive element 21c or 21a converted, which in turn into a movement 2c1 . 2c2 respectively. 2a1 . 2a2 of the drive element 21c respectively. 21a arranged movable element 2c respectively. 2a results.

Here are the assignments of the input signals 22a1 . 22a2 . 22b1 (Not shown), 22b2 (Not shown), 22c1 . 22c2 to the output signals 23a1 . 23a2 . 23b1 (Not shown), 23b2 (Not shown), 23c1 . 23c2 . 23d1 (Not shown), 23D2 (not shown) freely selectable and dependent solely on the programming of the transmission unit. In this respect, of course, an exemplary assignment is shown here.

The 2a and 2 B come from the Standard ISO 10968 , which deals with actuators of earthmoving machines, and thus correspond to the prior art, which, however, a clear presentation of the basic functions of an excavating machine is possible.

From the point of view of a dredger, you can see the command overview in a state-of-the-art excavator with a joystick that can be operated with the left hand 25a and a right-handed joystick 25b are arranged. Both joysticks 25a . 25b can be from a home position in which the central axis of the joysticks 25a . 25b is arranged perpendicular to the image plane, in each case v to the front v and to the rear h and to the left l and r to the right. These input movements v, h, l, r are respectively output movements of the vehicle 3 arranged movable elements 2a . 2 B . 2c . 2d assigned. In this case corresponds to the movable element 2a the vehicle cabin 4 , the movable element 2 B the first cantilever arm 15 , the movable element 2c the second cantilever arm 16 and the movable element 2d the excavator bucket 26 , The first cantilever arm 15 is with its first end 15a swiveling on the vehicle cabin 4 arranged, being at the second end 15b of the first cantilever arm 15 the second cantilever arm 16 with a first end 16a is arranged pivotably. At the second end 16b of the second cantilever arm 16 is again the excavator bucket 26 arranged pivotally. While the vehicle cabin 4 is pivotable about an axis which is parallel to the height direction 9c of the vehicle 3 is arranged, are the first 15 and the second cantilever arm 16 as well as the excavator bucket pivotally arranged about axes perpendicular to the height direction 9c of the vehicle 3 are arranged.

A basic position of the vehicle cabin 4 generally corresponds to the position in which the longitudinal direction 9a the vehicle cabin 4 is arranged parallel to the longitudinal extent of the chains shown and facing the driver in the direction of travel to the front.

The following descriptions are shown from the driver's point of view.

A pivoting movement of the left joystick 25a to the left, according to the standard, triggers a pivoting movement 2a1 the vehicle cabin 4 to the left and a pivoting movement of the left joystick 25a to the right r triggers a pivoting movement according to standard 2a2 the vehicle cabin 4 to the right. There is a pivoting movement of the left joystick 25a forward v, becomes the second boom arm 16 a pivoting movement 2c1 forward from the vehicle cabin 4 imposed during a pivoting movement of the left joystick 25a to the rear h a pivoting movement 2c2 of the second cantilever arm 16 to the rear in the direction of the vehicle cabin 4 he follows.

A pivoting movement of the right joystick 25b to the left, according to the standard, triggers a pivoting movement 2d1 the excavator bucket 26 to in the back towards the vehicle cabin 4 and a pivoting movement of the right joystick 25b to the right r triggers a pivoting movement according to standard 2d2 the excavator bucket 26 forward from the vehicle cabin 4 away. Is a pivoting movement of the right joystick 25b forward v, becomes the first cantilever arm 15 a pivoting movement 2b2 to the rear in the direction of the vehicle cabin 4 imposed while pivoting the right joystick 25b to the rear h a pivoting movement 2b1 of the first cantilever arm 15 forward from the vehicle cabin 4 done away.

According to the invention, for example, the initial movements 2a1 . 2a2 . 2b1 . 2b2 . 2c1 . 2c2 . 2d1 . 2d2 remain the same while described as the associated input movements are no longer the two joysticks 25a . 25b but the control rod element according to the invention 1 assigned.

The 3a - 3c show various embodiments of the combination of outer ring element according to the invention 6 and inner ring element 7 Here, for reasons of clarity, neither the control rod element 5 still the vehicle cabin 4 are shown. In the 3a the variant is shown, at the inner diameter 12 of the inner ring element 7 between two connection points 11a . 11b a handlebar element 13 is arranged. Here are the connection points 11a . 11b preferably selected so that between the two there is the maximum possible distance, which then the value of the inner diameter 12 equivalent. The longitudinal extension of the handle bar element is preferred 13 and the longitudinal extent of the inner ring member 7 arranged parallel to each other.

This first variant is suitable for the excavator operator to make a rotational movement out of the wrist or out of the elbow around the axis of rotation 28 exerts to the inner ring element 7 opposite the outer ring element 6 to turn. The shoulder remains untouched by this movement.

According to the variant 3b is not a handle bar 13 arranged so that the excavator operator outer ring element 6 and inner ring element 7 includes, either to pivot together, if at the same time the control rod element 5 to be pivoted, or around the inner ring element 7 opposite the outer ring element 6 if necessary, by the excavator operator the holding pressure on the outer ring element 6 minimized accordingly. Shown here is the variant in which the outer ring element 6 in the height direction 9c and width direction 9b the vehicle cabin 4 extends.

The representation according to 3c corresponds to the basic structure according to the illustration 3b ; However, here is the variant shown in which the outer ring element 6 in the height direction 9c and longitudinal direction 9a the vehicle cabin 4 extends. Also in this case, the assignments of the input movements 7a . 7b of the inner ring element 7 stay the same as the movements "clockwise 18a "And" counterclockwise 18b "Even with this arrangement of the outer ring element 6 from the driver's point of view.

All disclosed in the application documents features are claimed as essential to the invention, provided they are new individually or in combination over the prior art.
