摘要： A center differential gear adapted for use in a power transmission device for full-time type four-wheel drive vehicles includes a diff-carrier coupled with a power transmitting front casing covering the front diff-carrier of a front-wheel differential gear and arranged coaxially with the diff-carrier, a side gear coupled to the front wheels, and another side gear coupled to a gear mount casing which transmits power to the rear wheels. The diff-carrier of the center differential gear is supported between the side gear on the side driving the front-wheel differential gear and the gear mount casing in cantilever fasion. The other side gear is spline-coupled directly to the gear mount casing without passing through the diff-carrier.

摘要： A power transmission device for four wheel drive vehicle includes a differential motion limiting device, for limiting differential motion of a center differential device, which is made up by a wet-type frictional clutch and a hydraulic actuator. Under running condition, the frictional clutch is engaged by certain engaging force, and considering frictional coefficient of roads, the clutch is engaged with some slips so that torque distribution to front and rear wheels becomes even (50:50), then torque is distributed from the center differential device to front and rear wheels. The line pressure is applied to the hydraulic actuator through a regulator valve. In normal running condition, the regulator valve reduces the line pressure pre certain ratio, the reduced pressure is applied to the hydraulic actuator. In the case the manual valve being shifted to R range or low speed position, the regulator valve is switched to apply the line pressure directly to the hydraulic actuator. In the case of the manual valve being shifted to a low speed position, then from the low speed port of the manual valve, the line pressure is applied to a modulator valve where the line pressure is modulated, and applied to a back pressure port of a primary regulator valve to boost the line pressure up to certain volume.

摘要： A power transmission device for a full-time four wheel drive vehicle has a differential motion limiting device composed of a hydraulic frictional clutch such as a wet multiple disc type clutch. The friction clutch is disposed between a diff-carrier constituting a front wheel differential gear and a ring gear mount casing covering the diff-carrier and arranged coaxially with the diff-carrier. The ring gear mount casing is associated with the diff-carrier in a center differential gear, and the diff-carrier of the front wheel differential gear is associated with the left hand side gear in the center differential gear. Thus, when the friction clutch is engaged, the ring gear mount casing and the diff-carrier of the front wheel differential gear are integrally coupled with each other so that the rotation of the ring gear is transmitted directly to the front wheel differential gear, while the two elements in the center differential gear are integrally coupled with each other to lock the center differential gear.

摘要： Provided is a power transmission device for four-wheel drive vehicles of both the full-time type and part-time types, wherein a wet multiple-disc clutch is mounted in a ring gear covering the front-wheel differential gear and arranged coaxially with the differential gear. The wet multiple-disc type clutch is engaged by means of a hydraulic actuator in which a plurality of pistons are arranged in series. Hydraulic pressure is fed into oil chambers formed by the pistons through individual or common oil passages. The wet multiple-clutch constitutes a differential motion limiting device for stopping or limiting the differential motion of a center differential gear for the full-time four wheel drive, or constitutes a rear wheel drive switching unit for engaging and disengaging the power transmission between the ring gear mount casing and the transfer unit.
