- Actuators provided.
- Known actuators for classic manual transmissions are usually provided with a shift linkage.
- the drive energy, which is required for engaging and disengaging gears, is essentially completely applied by the driver, who initiates them manually in a coupled with the shift rod shift lever.
- actuating devices are known which have an electric motor or an arrangement of electric motors, by means of which the engagement and disengagement of gears is effected.
- Actuators of this type are - in various configurations - known for example in automated transmissions (ASG), in uninterruptible transmissions (USG), in electric manual transmissions (ESG) or in parallel transmissions (PSG) or dual-clutch transmissions (DKG) used.
- the actuator including the or the electric motors is referred to in the designs of the latter type as an actuator.
- the actuator is in the motor vehicle usually coupled with a so-called.
- Inner transmission circuit which has, for example, shift rails and / or shift forks and / or sliding sleeves, and can burden this inner transmission circuit.
- an electronic control unit controls the electric motors, which usually takes place as a function of various characteristic values, in particular operating characteristic values of the motor vehicle, such as engine speed or engine torque or the like.
- an operating element can be provided, via which the driver various modes (eg, driving forwards (D), reversing (R), parking (P), upshifting (+), downshifting (-)) can select, depending on which the electronic control unit drives the electric motors.
- various modes eg, driving forwards (D), reversing (R), parking (P), upshifting (+), downshifting (-)
- D driving forwards
- R reversing
- P parking
- upshifting (+), downshifting (-) can select, depending on which the electronic control unit drives the electric motors.

- actuating device that is to say a corresponding gear actuator
- a corresponding gear actuator is also disclosed in DE 10 2010 030 148 A1.
- the lanes or gear selection of a gearbox is made via two cams with corresponding grooves.
- the object of the present invention is therefore to show a corresponding actuator principle for an actuating device, in which these disadvantages can be at least reduced.
- the actuating device is, in particular, an actuating device for a motor vehicle transmission having a plurality of gear ratios.
- This actuator is equipped with a drive and a switching shaft, wherein the drive is directly and / or indirectly connected to the switching shaft.
- the shift shaft can perform at least two movements through the connection with the drive, wherein a gear is switched by a rotary movement and a gear can be selected by a linear movement.
- the shift shaft can of course also be equipped so that a gear is selected rotatively and a gear is switched by a linear movement.
- the drive is according to the invention connected to two eccentric gears, wherein the first eccentric is connected to the shift shaft in particular so that this connection is fixed in relation to the shift shaft, which concerns a rotary movement, that is, of the first Exzenterrad is directly or indirectly a Rotational movement of the shift shaft feasible.
- this connection between eccentric and shift shaft should be designed so that it is axially movable with respect to the shift shaft. In this way, on the one hand by the first eccentric a rotational movement, in particular a cyclic pivoting, be triggered, while by other elements, a linear movement relative to this rotary movement can be superimposed.
- the two movements can be switched independently of each other, however, the connection is formed by the drive and the two eccentric wheels so that only either a rotary or a linear movement of the switching shaft is generated.
- the second eccentric wheel is pivotally connected to the selector shaft. This can preferably take place via a cardan shaft, so that a rotary movement of the eccentric wheel is converted into a linear movement of the selector shaft for gear selection.
- This device can be arranged in particular so that it takes into account the spatial conditions of the engine compartment in the environment of the transmission.
- the drive is either rotary or linear acting. He may be part of a drive module and modularly attributable to the actuator, that is to be directly connected to her, so that he assigned to this, in particular of it is included.
- the actuating device in particular has a drive interface which can contact the drive or the drive module.
- the drive can be connected rotatably directly or indirectly via further toothed wheels or the like with a rotation axis of at least one of the eccentric wheels. Direct can mean in particular that the drive itself has an output which is identical to the axis of rotation, in particular both eccentric gears.
- the drive may alternatively have two outputs, that is, two output shafts, which is then identical to a respective rotation axis of exactly one eccentric wheel. Again, this is a direct rotary connection of the drive to the eccentric wheels.
- An indirect connection can be designed, for example, so that the drive itself at the end of an output shaft has a gear which runs either on the axis of rotation of both or each separately one of the axes of rotation of the eccentric, or with one or two gears is engaged, which in turn itself is rotationally fixed on the axis of rotation of one or both eccentric wheels.
- the drive can also indirectly via a transducer element with at least one of
- the drive is a linear drive, for example in the form of a hydraulic drive, whereby the linear movement is converted by the conversion of the transducer element into a rotary movement.
- This can be done for example via the combination of a rack and a pinion connected to these.
- a first indirect rotary drive is replaced by a second alternative rotary indirect drive
- this can be done by the connection point, that is, the drive interface is formed by a rotationally fixed on the or the axis of rotation of the eccentric gear.
- this gear can then engage a gear which is comprised of the drive module and is associated with an output shaft of the drive of the drive module.
- the eccentric wheels themselves are part of the drive module. The contact point between eccentric wheels and drive is then part of the drive module and can thus be easily replaced.
- the actuating device should be set up such that a movement of the drive in a first direction generates a gear selection and a movement in the other direction generates a switching movement.
- the direction of movement of the drive may be a direction of rotation, a circumferential direction or a linear direction.
- the two eccentric wheels are mounted in a preferred embodiment of the invention depending on a freewheel. These freewheels are reluctant to lock each other in different directions. In this way, a freewheel is released by a movement of the drive in one direction, while the other freewheeling acts blocking. This ensures that only one eccentric wheel is always driven in rotation via the drive.
- connection between the eccentric wheel and the selector shaft is in each case designed so that at least one cycle of the respective movement of the selector shaft is traversed by a complete revolution of the respective eccentric wheel.
- one cycle of a movement of the shift shaft is meant, for example, a gear engagement and disengagement, or an engagement of a gear on one side and a simultaneous subsequent engagement and disengagement of a gear on opposite sides of the control cam.
- this may mean a linear movement into the respective front and rear end positions of the switching cam or of the switching cam.
- the eccentric wheel is connected thereto via a first arrangement with the shift shaft.
- the first arrangement may comprise either at least one propeller shaft and a combination of a rack and a pinion, wherein the pinion directly or indirectly connected by a gear via a shaft teeth axially movable with the shift shaft, that is rotationally fixed.
- the second eccentric wheel is connected via a second arrangement with the switching shaft.
- the second arrangement preferably comprises at least one propeller shaft. This is at a first part of the rotary Movement of the eccentric wheel reaches a first "forward movement" of the selector shaft and in the second part of the rotative orbital motion of the eccentric a corresponding movement in the opposite direction caused by the selector shaft.Also here, by a complete rotation of the second eccentric at least one complete cycle of the selector movement the switching shaft can be effected.
- a motor vehicle transmission device which comprises an actuating device which has at least one of the features described here.
- the object is achieved by a motor vehicle drive train with a corresponding motor vehicle transmission device.
- FIG. 2 shows an actuating device with a direct rotary drive
- Figure 3 is an actuator with linear drive
- Figure 4 shows a second actuator with direct rotary drive.
- the eccentric wheels 8 and 9 have freewheels 6 and 7, in which the eccentric wheels 8 and 9 are mounted.
- the freewheels 6 and 7 are arranged contradictory, so that always a freewheeling acts blocking.
- the two eccentric wheels 8 and 9 are arranged on the common axis of rotation 31 so that they are just arranged by the combination of the gears 4 and 5 parallel to the electric motor 3 and its output shaft.
- the eccentric wheels 8 and 9 are connected to drive shafts 18 and 15, respectively, so that the rotary movements of the eccentric wheels 8 and 9 are converted into linear movements of the drive shafts 18 and 15.
- the propeller shaft 15 of the second eccentric 9 is then directly connected to the switching shaft 16, so that from a rotational movement of the eccentric 9, a linear movement 28 of the shift shaft 16 results.
- On the switching shaft 16 a switching cam 2 of a transmission 17 is arranged. By the linear movement 28, the switching cam 2 is then moved within the transmission 17 in shift gates, not shown here.
- the eccentric 9 is driven by a rotary movement of the electric motor 3 in a first direction. During this movement, the freewheel 6 of the first eccentric wheel 8 has a blocking effect, so that no movement is transmitted here.
- the freewheel 7 of the eccentric 9 acts blocking. Then, the freewheel 6 is released, so that the eccentric 8 can be rotated in the other direction.
- the eccentric 8 thus transmits a rotary movement to the transmission shaft 18, which is connected to a rack 10.
- the linear movement of the rack 10 is converted via a pinion 1 1, which is in operative connection with this rack 10, in a rotary movement of the gear 12.
- the gear 12 is part of a pair of bevel gears, consisting of the gears 12 and 14.
- the gear 14 is connected via a shaft toothing 13 with the switching shaft 16. In an axial movement of the switching shaft of this bevel gear 14 is not moved.
- a rotational movement of the bevel gear 14 is converted via the shaft teeth 13 in a rotary reciprocating motion about the axis of rotation 27 of the switching shaft 16.
- the switching cam 2 a gear and / or interpret. This switching movement is also cyclical.
- FIG. 2 shows an alternative embodiment of the invention, in which the electric motor 37 is arranged on the same axis of the eccentric wheels 8 and 9.
- the chain of action, starting from the second eccentric 9 to the switching shaft 16, is identical to the arrangement in Figure 1 and will not be described further here.
- Like reference numerals describe like elements.
- a rotation of the common axis of rotation 22 of the electric motor 37, eccentric 9 and freewheel 7 generates a block in the direction of the freewheel 7, so that, as described, a linear movement 28 of the switching shaft 16 is generated.
- a rotary movement of the electric motor 37 in the other direction is transferred via the freewheel 7 via a bevel gear pair 20, 29 in a rotation of the eccentric 8, which drives the propeller shaft 23.
- the propeller shaft 23 is connected to a rack 24, so that here, as already described in Figure 1, a rotary movement of the eccentric 8 results by means of the rack 24 in a rotary cyclic movement of a pinion 26.
- FIG. 3 shows an exemplary embodiment which essentially corresponds to the exemplary embodiment according to FIG.
- the electric motor 3 of Figure 1 has been replaced by a linear drive in the form of a hydraulic cylinder 35.
- the indirect connection between the hydraulic cylinder and the common axis of rotation 32 of the two eccentric wheels 8 and 9 is here produced by means of a piston rod 36 which is connected to a rack 33.
- the rack 33 engages in a pinion 34, which is rotationally fixed on the axis of rotation 32 of the two eccentric wheels 8, 9.
- FIG. 4 also corresponds in its mode of action to the embodiment according to FIG. 1.
- the drive in the form of a directly connected electric motor 41 is realized.
- the electric motor 41 has two output shafts, which coincide with the respective axes of rotation of the two eccentric wheels 8, 9.
- a switching movement of the cam 2 by a reciprocating rotation about the axis of rotation 27 of the shift shaft 16 and by a rotation of the electric motor 41st in the other direction by means of the eccentric 9 generates a selection movement of the shift shaft 16 in the linear direction 28, as has already been described with reference to Figure 1.
