Abstract:
A multi-stage transmission for a motor vehicle is disclosed. The transmission has a transmission input shaft, at least four planetary gear stages which are disposed one behind the other along a main axis of rotation, and at least one combined gear shift unit which is configured as a brake and has a rotatable coupling element as well as a friction-locking unit and a form-locking unit connected in parallel with the friction-locking unit, which are in each case provided in order to connect the rotatable coupling element fixedly to the housing. One of the planetary gear stages is associated with the combined gear shift unit and includes a transmission element which is permanently connected non-rotatably to the rotatable coupling element. The planetary gear stage associated with the combined gear shift unit includes a further transmission element which is permanently connected non-rotatably to the transmission input shaft.
