  • Patent number: 10047852
    Abstract: An actuator for selecting shift stages of a vehicle transmission comprises a lever housing, a selector lever, as well as a transfer device for transferring switching commands to the speed change gear. The actuator is characterized by am exchangeable module adapter which is arranged between the lever housing and the transfer device. The module adapter has the purpose of adapting the actuator in such a way that the ergonomic point of the actuator can be changed in vertical and/or horizontal direction and thus be adapted to different situations of assembly. The actuator can be adapted to be installed in different vehicle types primarily by selecting the appropriate module adapter and without requiring considerable structural changes.

  • Patent number: 9382999
    Abstract: An actuation device for selecting gear settings of a shift-by-wire gear shifting transmission comprises an actuation element, a mechanical transference for actuating the parking brake, and a coupling device disposed between the actuation element and the mechanical transference. An actuation of the transference occurs selectively by the actuation element only when the parking brake setting is selected or de-selected at the shift lever. It is possible, structurally as well as with respect to its installment, to simplify the transference mechanism necessary for the selective actuation of the transference means for the parking brake. Structural space and costs can be reduced, and the actuation device can be designed to be smooth and quiet.
