摘要： Disclosed herein is a driving state switching unit with a synchro-mechanism which employs a synchro-mechanism to perform switching of a driving state. The switching unit is equipped with a first gear (32) and a second gear (33) coaxially disposed, a gear connecting member (34) axially movable so that the first gear (32) and the second gear (33) can be connected, and a synchro-mechanism (35) interposed between the first gear (32) and the second gear (33). By moving the gear connecting member (34) by an electric actuator (50), the first gear (32) and the second gear (33) are connected, while they are being synchronized by the synchro-mechanism (35). When this occurs, control means (102) controls a supply current to the electric actuator (50), and judgement means (102) judges synchronization of the synchro-mechanism (35), based on a change in the supply current value to the electric actuator (50). With this, the judgement of the synchronization of the synchro-mechanism (35) is made possible without providing dedicated sensors, switches, etc., and an accurate judgement, corresponding even to an individual difference in the sliding resistance between members and a change in running conditions, is made possible.

摘要： A power transfer apparatus is provided with a rack/pinion type electric shift actuator for changing a traveling mode of a vehicle between high speed mode and low speed mode, and among full-time 4WD mode, 2WD mode, high direct-coupling 4WD mode and low direct-coupling mode. The apparatus further has a hydraulic multiple disc clutch for restricting a differential motion of a center differential gear when the traveling mode is in full-time 4WD mode and the traveling mode is changed over, and a hydraulic pump connected to a counter shaft, for supplying hydraulic pressure to the hydraulic multiple disc clutch.

摘要： A speed increasing/decreasing mechanism is interposed between a left-wheel axle and a right-wheel axle. The mechanism is constructed integrally of a speed increasing mechanism and a speed decreasing mechanism. The speed increasing mechanism is adapted to increase a rotational speed of the left-wheel axle and then to output the thus-increased rotational speed to a first intermediate axle. The speed decreasing mechanism, on the other hand, is adapted to decrease a rotational speed of the left-wheel axle and then to output the thus-decreased rotational speed to a second intermediate axle. A first coupling of the variable transmitted torque capacity type is interposed between the first intermediate axle and the right-wheel axle to transmit drive torque therebetween. A second coupling of the variable transmitted torque capacity type is interposed between the second intermediate axle and the right-wheel axle to transmit drive torque therebetween.
