PURPOSE: To enhance generation efficiency or fuel consumption by interposing a retarder for recovering power electromagnetically from brake energy between a clutch and a speed change gear.
CONSTITUTION: Rotor 3 of retarder 2 is coupled with the output shaft of a clutch 13 for transmitting/interrupting engine torque, and a field section 41 is disposed on the inside of outer peripheral poles 31, 32 whereas an armature 4 is disposed on the outside thereof. When a vehicle is braked, the field section 41 is conducted to excite the poles 31, 32 thus taking out brake power from the armature 4. When the engine is started or accelerated, the field section 41 and the armature 4 are conducted to drive the retarder 2 through a motor thus energizing engine torque.
