An apparatus includes an input-side rotating memberdriven by an engine (driving source), an output-side rotating memberfor driving an input member, such as a gear partof a rear differential (driving-force distributing mechanism)between wheels, a friction clutcharranged between the input-side rotating memberand the output-side rotating member, a carrier housing (stationary member)capable of accommodating the rear differentialand the friction clutch, an oil accommodating space (lubricant accommodating space) S formed in the stationary memberand an oil pumpdriven by the output-side rotating memberto supply the friction clutchwith oil

Driving-force transmission apparatus

A torque transmission coupling includes a rotating shaft and a drive pinion shaft for carrying out input and output transmission of a torque. A torque control part is arranged between the rotating shaft and the drive pinion shaft for controlling torque transmission between the rotating shaft and the drive pinion shaft on the basis of a frictional engagement caused by an electromagnetic force of an electromagnet. At least a portion of the torque control part is arranged in an outer periphery of a taper roller bearing rotatably supporting the drive pinion shaft, thereby allowing a shortening of an entire length of the torque transmission coupling.

Torque transmission apparatus and case structure

In order to make it possible to shorten an entire length, a torque transmission coupling is provided with a rotating shaft () and a drive pinion shaft () for carrying out input and output transmission of a torque, and a torque control means () arranged between the rotating shaft () and the drive pinion shaft () and controlling a torque transmission between the rotating shaft () and the drive pinion shaft () on the basis of a frictional engagement caused by an electromagnetic force of an electromagnet (), and at least a part of the torque control means () is arranged in an outer periphery of a taper roller bearing () rotatably supporting the drive pinion shaft ().

An outer rotational member has an inner wall surface and an outer wall surface. An inner rotational member is arranged inside the outer rotational member. Friction-clutch means is provided between the inner rotational member and the outer rotational member and is fastened by a thrust force. An oil lubricates at least the friction-clutch means. An oil space intervenes between the inner rotational member and the outer rotational member. Seal means seals the oil in the oil space. A first oil reservoir is recessed on the inner wall surface of the outer rotational member toward a side of the outer wall surface side.
