  • Publication number: 20240141990
    Abstract: A transmission device (5) for an electrically drivable vehicle axle (1) includes a transmission input shaft (7), a transmission output shaft (10) connected thereto via gear-wheel pairs (8, 9), and a parking lock device (15). The parking lock device (15) is arranged in a transmission housing (11) and includes an electric actuator (16) for actuating a locking pawl (18) engageable with a parking interlock gear (19) operatively connected to the transmission output shaft (10). The locking pawl and the parking interlock gear (19) are arranged in an interior space (14) of the transmission housing (11) that is acted upon by oil, and the electric actuator (16) is arranged in an oil-free interior space (13) of the transmission housing (11). The output shaft (21) of the electric actuator (16) extends through an intermediate wall (12) and is operatively connected to the locking pawl.

  • Publication number: 20240141988
    Abstract: An actuator for actuating a shift element in a transmission of a vehicle, particularly of a utility vehicle, includes a sensor device for detecting angular positions of a rotating component, for example, a shaft in an electric drive for a vehicle. The sensor device includes an annular encoder magnet fastened to a support pin supported on a front side of the rotating component so as to be fixed with respect to rotation relative to it such that the annular encoder magnet at least partially surrounds the support pin. The annular encode magnet is mounted on the support pin as a molded encoder magnet component.

  • Publication number: 20240060564
    Abstract: A gearbox actuator unit (14) is configured to be arranged on a gearbox (10) and includes a housing (22), a control device (24), and an actuator (28, 30). The housing (22) is configured to attach to a gearbox housing (12) and to seal the gearbox housing (12). The control device (24) is electrically connected to the actuator (28, 30) and activates the actuator (28, 30). A pinon of the actuator (28, 30) is configured to actuate a rack of a shift fork (18, 20) of the gearbox (10) and can be connected to the shift fork (18, 20) of the gearbox (10). The control device (24) and the actuator (28, 30) are arranged within the housing (22), with the pinion extending through an opening of the housing. A gearbox (10) with a housing (12) having an opening (44) receives the actuator unit (14), which closes and seals the opening (44).

  • Publication number: 20240060563
    Abstract: A gearbox actuator unit (12) is formed so as to be to be arranged on a gearbox (10). The unit (12) has a flange (14), an actuator (16, 18), a rack (20, 22) and a guide (24, 26). The flange (14) is formed to be connectable to a housing of the gearbox. The rack (20, 22) is received in an axially moveable manner within the guide (24, 26). The actuator (16, 18) meshes with the rack (20, 22) via a pinion (44, 46) and is formed so as to move the rack (20, 22) axially.

  • Patent number: 11686355
    Abstract: An actuating apparatus has a first and a second actuating element that delimit a pressure chamber. The actuating apparatus has a rotary decoupling bearing coupled via a compensation assembly to the second actuating element for joint movement along the spatial axis. The compensation assembly comprises a first ramp element which is supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis and a second ramp element coupled to the rotary decoupling bearing. An axial overall length of the compensation group along the spatial axis changes in the case of a rotation, of the first ramp element relative to the second actuating element.

  • Patent number: 11473632
    Abstract: An actuating device for a motor vehicle, including a housing and a multi-part working piston movable in relation to the housing. The multi-part working piston has a main piston and an adjusting piston, which pistons are formed in a manner movable axially with respect to each other to compensate for wear. A clamping device clamps the main piston and the adjusting piston in relation to each other in order to fix an operative length of the working piston. The main piston and the adjusting piston are partial pistons of the working piston. A shielding element for protecting the actuating device from dirt is arranged on the housing and a partial piston or on a first partial piston and a second partial piston or on an adjusting piston and on the clamping device.
