ABSTRACT:
A locking device for a motor vehicle transmission which includes a friction ring brought into frictional engagement with a gear wheel when engaging a reverse gear. The friction ring cooperates with a dog which is spring-loaded in an axial direction. The dog selectively displaces locking elements into a locking position for preventing engagement of the gear wheel. The friction ring is disposed non-rotatably and slidably on a driven shaft of the transmission between the gear wheel and the dog with the gear wheel being freely rotatable with respect to the driven shaft and adapted to be coupled to the driven shaft. The dog is disposed coaxially with respect to the driven shaft on integral portions of the transmission housing.
