摘要： A power transfer device for four-wheel drive includes a center differential of the bevel gear type arranged to split the driving torque from a power transmission into two torque delivery paths respectively for front-wheel drive and rear-wheel drive, a front-drive differential of the bevel gear type arranged coaxially with the center differential at one side thereof to transfer the split driving torque from a side gear of the center differential to front-wheel axles, an output gear for rear-wheel drive arranged coaxially with the center differential at the other side thereof to transfer the split driving torque from another side gear of the center differential to rear-wheel axles, and a limited-slip differential in the form of a viscous coupling assembled with a mounting case for the output gear to effect limited-slip torque proportional to the difference in rotational speed between the side gears. In the transfer device, a clutch mechanism is arranged between the center differential and the mounting case for the output gear to selectively render the limited-slip differential inoperative.

摘要： A differential gear for automotive vehicles comprising a washer interposed between the backs of pinions and the inner surface of a differential casing and fitted to a pinion shaft. The washer has at most a thickness of l tan.alpha. wherein l represents a displacement from an uncompressed condition of a spring washer to a compressed condition thereof exhibiting a predetermined pressure against the side gears. With this arrangement, the pinions may be installed into the differential casing without applying any pressure through the spring washers to the side gears, and after installation of the pinions into the differential casing, pressure between the meshed gear teeth of the side gears and the pinions may be desirably determined.
