Abstract

The invention relates to a shifting device (10) for a motor vehicle, said shifting device comprising a first coupling member (12) which can be selectively coupled with a second coupling member ( 14) Form-fitting rotational coupling. In this case, in the disconnected state, the first coupling component (12) is rotationally decoupled from the second coupling component (141). In the friction fit state, the coupling members (12, 14) are frictionally coupled in rotation via the first friction fit ring (18) and the second friction fit ring (20). In the form-fitting state, the steering ring (24) is rotationally coupled to the first coupling member (12) and the second coupling member (14) in a form-fitting manner such that the first and second coupling members and the The actuation ring is positively connected. In addition, the invention relates to a motor vehicle transmission, in particular a fully automatic multi-speed transmission, having such a shifting device (10).

Description

technical field [0001] The invention relates to a shifting device for a motor vehicle, in particular a fully automatic multi-speed transmission, which has a first coupling member which can be selectively coupled to a second The components are rotationally coupled in a form-fitting manner. [0002] Furthermore, the invention relates to a motor vehicle transmission, in particular a fully automatic multi-speed transmission, having such a shifting device. Background technique [0003] For power transmission, in vehicle engineering, besides manually shifted transmissions, automatic transmissions are also used, in particular multi-speed fully automatic transmissions with hydrodynamic torque converters and planetary transmissions. [0004] Such fully automatic multi-speed transmissions function as load-controlled transmissions with uninterrupted traction, wherein the power flow takes place via the planetary gear sets and the gear changes are effected by coupling and decoupling of ...
