Definitions

  • the invention relates to an actuating device for a gear change transmission, for example for an automatic transmission with shift-by-wire operation, according to the preamble of patent claim 1.
  • Gear change transmissions of motor vehicles are usually controlled or switched by means of an operating device arranged in the grip region of the driver.
  • actuating elements such as shift levers or selector levers are regularly used, which are arranged, for example, between the front seats of the motor vehicle.
  • Actuators or selector lever for gear change are varied. For example, to give the driver for reasons of safety and ergonomics a realistic feeling of transmission actuation is required for generic controls that not only gives the driver visual but also clear haptic or tactile feedback on the current switching or operating state of the transmission become.
  • the lack of mechanical connection between the transmission actuation and the selector lever means that the transmission state or any shift locks engaged in the transmission no longer directly affect the state of the selector lever.
  • the driver can thus not readily recognize by means of certain on the selector lever perceptibly blocked switch positions or ranges of movement that the corresponding lever positions, speed levels or gear states in the current driving state are not allowed and thus can not be selected.
  • the selector lever points at a monostable Actuator on a stable (middle) position and usually several non-stable positions.
  • a monostable Actuator on a stable (middle) position and usually several non-stable positions.
  • only a few of the mechanical total available selector lever positions come into question for the actual shifting operation.
  • mechanically possible selector lever positions may or may not trigger any meaningful shift operation, and must therefore be actuated locked to give the driver on the selector lever a consistent feel and reliable feedback of the shift operation.
  • a monostable selector lever if the transmission is in the state "P" as the parking brake, can not continue to move forward in the direction of travel, even if the monostable selector lever would initially be free to move forward. Rather, a corresponding actuator must ensure that the selector lever in this example case can only be moved backward relative to the direction of travel.
  • Direct locking electromagnets are significantly limited in terms of variability for different locking combinations or to realize different different ranges of motion for the selector lever.
  • simple direct-locking electromagnets in the worst case can lead to Hakein in the operation, especially if the switching state of such electromagnetic actuators in certain operating conditions of the vehicle transmission should be changed simultaneously with the operation of the selector lever.
  • the blocking device should also manage in the case of a complex blocking logic with the lowest possible number of actuators, and it should be reliably prevented undefined operating conditions or a Hakein the selector lever. Furthermore, the actuator should make do with the smallest possible space and have low energy consumption.
  • the actuating device comprises a - within at least one shift gate movable - selector lever with at least three driving position, as well as a base and a locking device.
  • the locking device is used for the controllable restriction of the range of movement of the selector lever in dependence, in particular, on the switching state of the transmission or on the driving state of the motor vehicle.
  • the actuating device is characterized in that the locking device comprises a movable by means of an actuator stop abutment with end stops, wherein a connected to the selector lever stop element between the end stops back and forth and can be brought to the end stops to the plant.
  • the actuating device according to the invention can be realized independently of how the actuator movement of the stop slot is structurally realized.
  • the actuator device for this purpose comprises a slider with a ramp device.
  • the stop link according to this embodiment has a driver element, wherein the driver element can be brought into engagement with the ramp device in such a way that a movement of the slider over the ramp device and the driver element is converted into a corresponding movement of the stop guide.
  • the required high gear ratio between the actuator drive and the movement of the stop cam can be achieved cost-effective and space-saving in the base area of the actuator.
  • designed as a ramp and driver gear ratio between the actuator drive and stop gate such a shape without additional aids are self-locking, so no further locks or actuators to determine the stop guide are required.
  • the slide is designed as a linear slide and thereby preferably provided with a linear toothing, wherein the linear toothing with the pinion of an electromotive servo actuator can be brought into engagement.
  • the slider can in particular be integral with the Linear teeth are formed, whereby further tool and assembly costs can be saved.
  • abutment link is rotationally pivotally connected to the base of the actuating device, wherein the pivot axis of the stop link preferably coincides substantially with the pivot axis of the selector lever.
  • the storage of the stop slot can thus optionally take place on one and the same bearing axis as the storage of the selector lever.
  • a locking recess is preferably integrally connected to the stop element of the selector lever, wherein the locking recess can be brought into engagement with an actuatable switchable locking projection.
  • the locking recess can be formed in the simplest case as a connected to the stop element of the selector lever locking slot, and the locking projection as an armature of an electromagnetic Sperractuators.
  • the selector lever is monostable. This means that the selector lever spring-loaded after each switching operation returns to the same center position. This is particularly advantageous in the operation of shift-by-wire-controlled transmissions, as in this way to a motor tracking of the selector lever at about automatically inserted gear stages - such as in the case of an automatically inserted by "Auto-P" parking brake - can be waived. Instead, in such monostable selector levers primarily only the display of the gear unit speed must be tracked or respectively updated and adapted to the current state of transmission.
  • the latter is important in a monostable selector lever inasmuch as the center position, which is always automatically resumed by the selector lever after actuation, can first be assigned to any actual switching state of the transmission.
  • the center position which is always automatically resumed by the selector lever after actuation, can first be assigned to any actual switching state of the transmission.
  • the driver is only indicated by a corresponding variable indicator on the selector lever or on the vehicle fittings.
  • a conventional multi-stable selector lever with multiple stable selector lever positions can be modeled in relation to the fact that the actual mobility of the selector lever depends on the gear in each case actually engaged gear even with a monostable selector lever , If, for example, the parking brake is engaged in the transmission, a conventional selector lever can not be moved forward by a further step, but generally by two or three steps backwards, before it stops at the actuating device opposite the parking brake position or at the opposite end of a selector lever strikes.
  • this intuitive operation and haptic recognizability of the transmission state beneficial behavior can be relatively easily realized even with a monostable selector lever by - the corresponding permissible range of movement of the selector lever so within the entire constructive motion window - by appropriate positioning of the stop link with the end stops is shifted to the selector lever, that movements of the selector lever only in that direction and only as many switching stages are possible, as this logically corresponds to the engaged transmission drive.

  • the additional locking device comprises an electromagnetic actuator 16, the anchor pin engages with appropriate control of the actuator 16 in the locking lever 17 connected to the selector lever 17 and thus locks the selector lever 1 in the illustrated middle position.
  • the locking of the selector lever 1 in the middle position is for example the haptic signaling to the operator or driver that due to the vehicle or transmission state currently no switching commands can be performed. This is due to the shift lock, for example, when the vehicle is at a standstill when the transmission is in the park locked state, and when the brake pedal is not depressed at the same time.

  • the stop element 18 is integrally connected by means of the boom 20 with the selector lever 1. It follows that the positioning of the segment-shaped recess 19 - defined by means of appropriate positioning of the pivotable Antschskulisse 5 via the actuator 14 and the linear slide 6 - relative to the base 2 of the actuator each have a specific fixed range of motion for the selector lever 1.

  • the stop link 5 is spent in this case in its lowest position shown in FIG. 3 and 4.
  • the relative position of selector lever 1, stop cam 5 and linear slide 6 shown in FIG. 3 could thus be linked, for example, to the transmission state "parking lock", in which the selector lever can no longer be moved forward but can be moved rearward by a plurality of positions.

  • an actuating device is provided with a locking device, which in particular has the advantage over the prior art that it manages with a minimum number of actuators even in the case of complex locking tasks. Additional advantages are achieved in the form of structurally simple and thus cost-saving and robust design and in the form of low energy consumption. Furthermore, undefined operating states or a hooking of the selector lever can be prevented reliably with any simultaneous actuation of selector lever and activation of the locking device. Finally, the range of movement of the selector lever can be largely variably freely adjusted to match the respective operating state of the gearbox, and in principle any desired number of selector lever positions can be provided without space problems or overlapping of discrete locks.
