ABSTRACT:
The power train of a motor vehicle employs an automated transmission and an automated clutch between the transmission and the combustion engine. The clutch is automatically disengaged prior to, and is automatically reengaged after, each selection of a particular gear of the transmission. A common first actuator (such as a reversible stepping motor) is employed to select the condition of the clutch and to select various gears, and a second actuator is used to effect actual shifting of the transmission into or from a selected gear. The connection between the first actuator and a clutch operating member comprises a reciprocable or rotary first cam, and the connection between the first actuator and a gear selecting member comprises a preferably rotary second cam which receives motion from the first cam.
