Definitions
- Gear selection device for an automatic transmission of a motor vehicle
- the invention relates to a gear selection device for an automatic transmission of a motor vehicle according to the preamble of patent claim 1.
- DE 43 04 250 Cl describes a drive stage selection device for an automatic motor vehicle transmission for preselecting different drive stages ("P", "R”, “N” and “D"), in which an actuating element in the form of a selector shaft is used in normal operation one - actuator can be adjusted in the form of an electric motor.
- a parking lock is engaged in the “P u ” gear step, thus securing the motor vehicle against rolling away.
- the actuator is operatively connected to the actuating element via a drive element in the form of a crank and an output element in the form of a rocker arm.
- the drive element is connected to the output element by means of a coupling.
- the coupling can only transmit forces or torques that are less than a force or torque limit. If the limit value is exceeded, the coupling is pushed together or pulled apart, so that the output element is decoupled from the actuator.
- the gear selection device has an emergency actuation device in the form of a manually operated unlocking lever, with which the gear selection device can be actuated in the event of a fault, for example failure of the actuator or an energy source in the form of a vehicle battery.
- the emergency actuation device When the emergency actuation device is used, the force or torque limit value is exceeded and so regardless of the Position of the actuator, a position which corresponds to the gear stage "N", is set via the output element.
- the output element executes a relative movement with respect to the drive element. After an emergency actuation, the output element is decoupled from the drive element be restored.
- the gear selection device after an emergency operation and subsequent correction of the error which is the Emergency operation
- the gear selection device after an emergency operation and subsequent correction of the error which is the Emergency operation
- the automatic transmission can be designed as a planetary gear, a continuously variable transmission or as an automated manual transmission with single or double clutch.
- the actuator is controlled by a control device and can be designed as an electrical, • hydraulic or pneumatic actuator.
- the actuator is in drive connection with the actuating element via the drive element and the output element.
- the actuating element can be designed, for example, as a selector slide of the automatic transmission, by means of which different switching positions can be set in a hydraulic control, or as a parking lock actuating element, for example in the form of a parking lock cone. If the emergency actuation device is designed accordingly, any speed step of the automatic transmission or any position of the parking lock can be set in the event of a fault. Likewise, the emergency actuation device can be designed so that only a certain speed level or position of the parking lock can be set in the event of a fault.
- the gear selection device has two actuation directions, one actuation direction being in the position “P” in which the parking lock is engaged and the second actuation direction is oriented away from “P”.
- the position "P" is designed as an end position of the gear selector.
- the force or torque limit values for the two actuation directions are different in each case and the force or torque limit value in one actuation direction is greater than the maximum force or the maximum torque which can be applied by means of the emergency actuation device.
- only one movement direction is only one movement direction.
- the connection between the drive element and the driven element is thus comparable in operation to a ratchet known per se.
- the connection mentioned can also be designed such that a direction of movement is blocked independently of an actuating force or an actuating torque.
- only the drive step “P w can be engaged by means of the emergency actuation device. Since the opposite direction of movement is blocked, "P" can no longer be left after being inserted once using the emergency operating device.
- the motor vehicle is thus secured against rolling away by means of the parking lock. This ensures effective theft protection for the motor vehicle. Coupling ensures particularly safe operation the parking lock with an ignition lock of the motor vehicle, an ignition key can only be removed if the parking lock has been inserted with the actuator during normal operation or with the emergency actuation device in the event of a fault.
- the gear selection device has an emergency unlocking device, by means of which the gear "P" and thus also the parking lock can be disengaged.
- the emergency unlocking device can exert a greater force or a greater torque than the emergency actuation device and the one necessary for disengaging "P" Exceed force or torque limit. This enables the emergency unlocking device to initiate a movement out of gear "P". For example, gear "N” can be engaged and the parking lock can thus be disengaged. This makes it possible to tow the motor vehicle in the event of a fault.
- the emergency release device is in particular arranged at a distance from the emergency actuation device and can be actuated, for example, only with the aid of a special tool.
- the emergency release device can also be secured by means of a locking device. In addition to the possibility of towing the motor vehicle, this also ensures protection against theft.
- the emergency actuation device and / or the emergency release device can be actuated by a vehicle driver who is in a place provided for him.
- the driver of the vehicle can thus secure the motor vehicle from the driver's seat with the parking lock and can also unlock it, for example for towing, from the driver's seat. This means that he does not have to leave the unsecured motor vehicle in the event of a fault, so the risk of the motor vehicle starting to move in an uncontrolled manner and endangering the driver or other road users is very low. This ensures safe operation of the motor vehicle.
- the actuation of the emergency actuation device and / or the emergency release device can be coupled with the actuation of further devices of the motor vehicle, for example the actuation of a parking brake.
- the emergency actuation device and / or the emergency unlocking device has an energy store, which can be triggered by the vehicle driver and / or by means of a trigger actuator. This makes operation particularly easy and convenient for the driver. In addition, it can be ensured in a simple and cost-effective manner that only one speed level can be set with the emergency actuation device or the emergency release device.
- the emergency actuation device can advantageously direction is actuated and the parking lock is engaged when the driver removes the ignition key or opens a vehicle door.
- the control device which controls the release actuator has, in particular via a second power source, for example a battery, in order 'to ensure operation also in case of failure of a power supply of the motor vehicle. This ensures particularly safe operation of the motor vehicle.
- the energy store is designed as a pneumatic or hydraulic pressure store.
- the pressure accumulator After the pressure accumulator has been triggered, it can be refilled by means of a pump, which in particular can also have other tasks, and thus be made ready for operation again.
- This resetting of the pressure accumulator is independent of the other actuation of the gear selector. This means that the actuator and all other elements of the gear selector are not subjected to the reset.
- the other elements of the gear selection device can be designed purely for the actuation elements. This enables a particularly cost-effective design of the gear selection device.
- the energy store can be designed as a spring store, for example.
- the drive element has a mainly circular inner contour and the driven element has a mainly circular outer contour.
- the drive element at least partially surrounds the output element. This enables a compact design of the combination of the receiving and driven element, which requires little installation space.
- the control device uses a position sensor to position the Output elements can be detected.
- a measuring contour is arranged on the output element, which is in operative connection with the sensor.
- the control device can thus measure the position of the actuating element, for example the selector slide or the parking lock actuating element, that is to say the effect achieved by the gear selector device. Since the drive element and the driven element are mainly circular, the position of the drive element with respect to the driven element is not important. The control of the actuator takes place solely on the basis of the position of the transmission element.
- the drive element is made in one piece with an element of the actuator. This eliminates the otherwise necessary positive or non-positive coupling of the actuator to the drive element.
- the gear selection device can thus be constructed with a few components, which means that only a small installation space is required and simple and inexpensive installation is made possible.
- the actuator can be designed, for example, as an electrical transverse flux machine.
- Fig. 5 shows an emergency operating device with a
- Fig. 6 shows an emergency operating device with a pneumatic pressure accumulator.
- the 1 has a selector lever 11, by means of which a vehicle driver can set the driving stages "P", “R”, “N” and “D” of an automatic transmission (not shown) of a motor vehicle.
- the speed levels can be set sequentially in the order mentioned.
- the selector lever 11 is in signal connection with a control device 12, which controls an actuator in the form of an electric motor 13 in accordance with the position of the selector lever 11.
- the electric motor 13 drives a worm wheel 17 via an output shaft 14, bevel gears 15 and an intermediate shaft 16.
- the worm wheel 17 engages in a worm toothing (not shown) of a drive element 18 and can thus transmit the movements of the output shaft 14 of the electric motor 13 to the drive element 18.
- the drive element 18 has an essentially annular basic shape. On a cylindrical outer contour 19, the drive element 18 has the worm toothing mentioned, which is indicated by a broken circle 20. On a circular, cylindrical shaped inner contour 21, the drive element 18 has an internal toothing 22, in which, as shown in FIG. 1, a locking pin 23 engages.
- the locking pin 23 has a cylindrical base body 24 and a tooth 26 arranged on an end face 25 of the cylindrical base body 24.
- the tooth 26 has two flanks 27 and 28 which have different angles of inclination ⁇ and ⁇ with respect to the end face 25.
- the internal toothing 22 of the drive element 18 is designed in accordance with this angle of inclination ⁇ , ⁇ .
- the locking pin 23 is arranged in a cylindrical recess 29 of an output element 30, which is partially enclosed by the drive element 18.
- the locking pin 23 is acted on a bottom surface 31 by a spring 32 with a force which presses the locking pin 23 with the tooth 25 into the internal toothing 22 of the drive element 18.
- a drive connection is thus established between the drive element 18 and the driven element 30.
- the output element 30 also rotates in normal operation of the gear selector 10.
- a force or torque limit value can be defined for each direction of movement, which limit values or forces transmitted between the drive element 18 and the output element 30 cannot exceed. If the limit value is exceeded, the locking pin 23 is pressed into the recess 29 by a force opposite to the force of the spring 32 and the drive element 18 and the driven element 30 can rotate independently of one another. The force that presses the locking pin 23 into the recess 29 is greater, the greater the angle of inclination ⁇ , ⁇ of the flanks 27, 28 relative to the end face 25 of the locking pin 23.
- the angle of inclination ⁇ of the flank 27 is smaller than that The angle of inclination ⁇ of the flank 28 can transmit a greater force in a counterclockwise actuation direction than in a clockwise actuation direction.
- the angle ⁇ is chosen so that the locking pin 23 is never fully pressed into the recess 29 in a counterclockwise direction of movement.
- the angle of inclination ⁇ can be, for example, in a range from 100 ° to 105 °, in particular 102.2 °, and the angle of inclination ⁇ in a range from 136 ° to 142 °, in particular 139 °.
- the output element 30 has a cylindrical base body 33 with a total of three recesses 29, in each of which a spring 32 and a locking pin 23 are arranged.
- the base body 33 is largely enclosed by the drive element 18.
- three fastening eyes 34, 35, 36 are arranged distributed around the circumference.
- a measuring contour 37 is attached to the non-enclosed part.
- the driven element 30 is connected to a parking lock cone 38 via the fastening eye 34.
- a parking lock not shown, is inserted, thus securing the motor vehicle against rolling away.
- the driven element 30 is connected to a selector slide 39 of the automatic transmission. Different switching positions can be set in a hydraulic control by means of the selector slide 39. In the position of the selector slide shown, the shift position “P u in the automatic transmission is set.
- the measuring contour 37 on the output element 30 actuates a position sensor 40, which is in signal connection with the control device 12.
- the control device 12 thus detects the position of the output element 30 and thus also the position of the parking lock cone 38 and the selector slide 39 Adjustment of the parking lock cone 38 and the selector slide 39 are the task of the gear selector 10, so the result of the adjustment can be checked with the position sensor 40.
- control device 12 controls the electric motor 13 so that the output element 30 and thus the parking lock cone 38 and the selector slide 39 assume a position corresponding to the position of the selector lever 11. All components of the Fahrgenpartyl coupled 10 previously mentioned are disposed within a not 'shown housing of the automatic transmission.
- the output element 30 is firmly connected to an emergency actuation lever 41, which also rotates when the output element 30 rotates.
- the emergency operating lever 41 is connected to an ignition lock 43 by means of a Bowden cable 42. This ensures that an ignition key (not shown) can only be removed from the ignition lock 43 when the emergency actuation lever 41 is in the position shown and thus the automatic transmission is in the position "P".
- the parking lock is also engaged and the motor vehicle is against Rolled away secured.
- a mechanical emergency actuation device 44 is arranged between the emergency actuation lever 41 and the ignition lock 43, through which the Bowden cable 42 is carried out.
- the gear selection device 10 can be actuated by means of the emergency actuation device 44.
- the emergency actuation device 44 has a stick 45 and a pulling iron 46.
- the Bowden cable 42 is pulled in the direction of the ignition lock 43 by means of the pulling iron 46.
- the emergency actuation lever 41 and the driven element 30 are thus rotated in the direction of the position “P”.
- the actuation can be repeated until “P” is reached.
- the force applied by the emergency actuation device 44 or the torque applied is greater than the force or torque limit value which can be transmitted between the drive element 18 and the output element 30.
- the locking pin 23 is thus pressed into the recess 29 and the drive connection between the drive element 18 and the driven element 30 no longer exists.
- the output element 30 can thus be rotated independently of the drive element 18.
- the emergency actuation device 44 can be arranged in the interior of the motor vehicle and can be actuated by the vehicle driver from the driver's seat.
- the stick 45 can be firmly connected to the emergency actuation device 44 or can only be inserted if necessary.
- a rod can also be arranged between the emergency actuation lever and the ignition lock, which forces in the direction of the emergency actuation lever and in the direction of the ignition lock can transmit.
- an appropriately designed emergency actuation device all speed levels can be engaged in the event of a fault.
- the locking bolts can also be arranged in recesses in the drive element instead of in recesses in the output element.
- FIG 5 shows an emergency actuation device 144 in a second embodiment. For reasons of clarity, only one output element 130 and one emergency actuation lever 141 are shown of the gear selection device. In the illustrated position of the emergency actuation lever 141, the gear selector is in the position "D", the position for forward travel.
- the emergency operating lever 141 has a bore 151 through which a pull rod 152 is guided.
- the pull rod 152 is enclosed in a partial area by a spring accumulator in the form of a coil spring 153.
- the coil spring 153 is tensioned and is kept under tension by a trigger pin 154.

- the control device 11.2 is also in signal connection with a selector lever 111, an ignition lock 143 and a door sensor 156.
- the door sensor 156 detects when a driver's door (not shown) of the motor vehicle is opened.
- the electromagnet 155 is actuated when an ignition key (not shown) is removed from the ignition lock 143 or when the driver's door is opened so that the trigger pin 154 releases the coil spring 153 and the latter relaxes ,
- the pull rod is used 152 the emergency actuation lever 141 and thus also the driven element 130 are moved into the position "P".
- the parking lock is now engaged.
- the force exerted by the coil spring 153 or the torque applied is greater than the force or torque limit value which lies between the Drive element and the output element is transferable.
- the output element 130 and thus also the emergency actuation lever 141 can be rotated again by means of the actuator. If a position other than "P" is set again, the coil spring 153 is tensioned again and the trigger pin 154 can assume the position shown again. The emergency actuation device 144 is thus ready for operation again.
- the driving step “N” can be engaged by means of an emergency unlocking device 157 and the parking lock can thus be released.
- the emergency actuation lever 141 has a second bore
- the pull rod 159 is partially enclosed by a second spring accumulator in the form of a second coil spring 160.
- the coil spring 160 is tensioned and is held under tension by a second release pin 161.
- the trigger pin 161 is connected to an unlocking lever 162 which can be actuated by the vehicle driver.
- the unlocking lever 162 is actuated, the release pin releases the coil spring 160, which then relaxes.
- the pull rod 159 the emergency actuation lever 141 is thus brought into the position “N” and so that the parking lock was released. The motor vehicle can thus be moved again.
- the force applied by the coil spring 160 or the torque applied is greater than the force or torque limit value which can be transmitted between the drive element and the output element.
- the emergency unlocking device 157 is reset in accordance with the reset of the emergency actuating device 144.
- a signal for triggering the spring-loaded device can also be generated by the driver using a signal transmitter (not shown) or when another door of the motor vehicle is opened.
- the control device 112 can be supplied with voltage by a second energy source, not shown, for example a second battery.
- the driver can be shown by means of a display that the parking lock is engaged when the ignition key is removed or when the driver's door is opened.
- the display can function, for example, without a voltage supply from the vehicle battery or with a voltage supply from the second energy source mentioned.
- FIG. 6 shows an emergency actuation device 244 in a third embodiment. For reasons of clarity, only one output element 230 and one emergency actuation lever 241 are shown of the gear selection device. In the illustrated position of the emergency operating lever 241, the gear selector is in the position "D".
- the emergency operating lever 241 has a bore 251 through which a pull rod 252 is guided.
- the pull rod 252 is connected to a piston 271 of an actuating cylinder unit 272.
- a pressure chamber 273 of the actuating cylinder unit 272 facing the emergency actuation lever 241 is by means of a compressed air line 274 connected to a pneumatic pressure accumulator 275. Air is stored in the pressure accumulator 275 under increased pressure.
- the compressed air line 274 can be shut off by means of a valve 276 which is controlled by a control device 212.
- the valve 276 serves as a trigger actuator.
- the control device 212 is also in signal connection with a selector lever 211, an ignition lock 243 and a door sensor 256. In normal operation of the gear selection device, the valve 276 is closed and the pressure chamber 273 is thus separated from the pressure accumulator.
- the valve 276 is opened when an ignition key (not shown) is removed from the ignition lock 243 or when the driver's door is opened, and the pressure chamber 273 is thus connected to the pressure accumulator 275.
- the pressure in the pressure chamber 273 thus rises sharply and a force acts on the piston 271, which is directed away from the emergency actuation lever 241.
- the piston 271 thus moves away from the emergency actuation lever 241 and, by means of the pull rod 252, rotates the emergency actuation lever 241 and thus also the output element 230 into the position “P”.
- the force exerted by the pressure in the pressure chamber 273 or the torque applied is greater as the force or torque limit value that can be transmitted between the drive element and the output element.
- the output element 230 and thus also the emergency actuation lever 241 can be rotated again by means of the actuator. If a position other than "P" is set again, the piston 252 is brought back into the position shown.
- the pressure accumulator 275 is filled again by means of a pump 277, which is controlled by the control device 212.
- the emergency actuation device 244 is thus ready for operation again .
- the pressure accumulator can also be designed as a hydraulic pressure accumulator. This does not change the mode of operation of the emergency actuation device.
- the gear selection device and the automatic transmission can be controlled by a common or two separate control devices.
- Parts of the gear selection device such as the actuator, can also be arranged outside the housing of the automatic transmission.
