Abstract: A power transmission device is used to distribute torque from a power source to an external device and an auxiliary device. The power transmission device is comprised of a first bearing and a second bearing both secured to a stationary member, a first sprocket rotatably supported by the first bearing, a second sprocket capable of being drivingly coupled with the auxiliary device, a chain coupling the first sprocket with the second sprocket, a rotary shaft rotatably supported by the second bearing, which is drivingly coupled with the power source and drivingly engageable with the external device to transmit a first part of the torque to the external device, and a joint drivingly linking the rotary shaft with the first sprocket to transmit a second part of the torque to the first sprocket.

Abstract: A hybrid driving force transmission device includes an engine (E), a motor-clutch unit (MC), and a transmission unit (T). The motor-clutch unit (MC) is coupled to the engine (E), and includes a multi-plate dry clutch (7) and a slave cylinder (8). The transmission unit (T) is coupled to the motor-clutch unit (MC), and includes a transmission housing (41), a V-belt type continuously variable transmission mechanism (42), and an oil pump (OP). A cylinder housing (81) which comprises a first clutch pressure oil passage (85) communicating with the slave cylinder (8) is provided in the motor-clutch unit (MC). By coupling the motor-clutch unit (MC), a second clutch pressure oil passage (47) is brought into communication with the first clutch pressure oil passage (85) in the cylinder housing (81). An end plate (45) having the second clutch pressure oil passage (47) is provided in the transmission unit (T).
