Abstract

Abstract A planetary gear change-speed transmission for vehicles, especially an automatically shifting change-speed transmission for motor vehicles in which two concentrically arranged lamellae friction clutches are provided at the input, and an output planetary gear set is shifted by means of a free-wheeling device and a lamellae friction device acting as a brake on the ring gear at the output of the transmission; the ring gear of the planetary gear set coordinated to the output and the outer race of the free-wheeling device are inserted into an undulatory sheet metal sleeve which simultaneously forms the inner disk carrier for the brake.
