Manual gear change mechanism for vehicle - has synchromesh units and switching arms or forks on rods with locking elements which prevent simultaneous switching of both arms

摘要

The gear change mechanism has several synchromesh units (1,2,3,4) actuated by switching arms (5,6) or switching forks (7,8) on switching rods (12,13) in which locking elements are provided which prevent, on the actuation of one switching arm, the actuation of the other switching arm or rod. The locking action for the switching arms is achieved by locking rocker arms (14) and for the switching rods by balls or a locking plate controlled by a lever (26). ADVANTAGE - Mixed unit manual gear box in which it is not necessary to connect the switching arms and the switching rods.
