Claims

[Scope of utility model registration request]

A transmission is assembled to one side of the engine in which the crankshaft is arranged to extend in the width direction of the vehicle body, and includes an input shaft coaxial with the crankshaft and an output shaft parallel thereto, and a casing of the transmission. a ring gear that is rotatably supported by the casing and always meshes with an output gear provided on the output shaft; and a ring gear that is arranged coaxially with the ring gear and is assembled to the casing of the transmission at the rear (or front or below) of the engine. a bevel gear type front wheel (or rear wheel) differential rotatably supported by a transfer case; a ring gear mount case that integrally supports a drive bevel ring gear and is rotatably supported by the transfer case; and a ring gear mount case that is coaxially assembled within the ring gear mount case and that is attached to the front wheel (or rear wheel).
a bevel gear-type intermediate differential device that is arranged coaxially with the differential device for dividing and transmitting power to the front wheels and rear wheels; (or front wheels), a side gear that is provided with a drive pinion shaft integrally having a bevel gear that constantly meshes with a drive bevel ring gear, and that is located on the intermediate differential device side of the front wheel (or rear wheel) differential device. an axle connected to the intermediate differential so as to transmit power passes through both side gears and a ring gear of the intermediate differential and protrudes laterally;
One side gear of the intermediate differential is connected to the case of the front wheel (or rear wheel) differential for power transmission by a first hollow shaft rotatably assembled on the axle, and the intermediate differential The other side gear of the device is coupled to the ring gear mount case in a power transmitting manner, and the case of the intermediate differential is coupled to the ring gear in a power transmitting manner by a second hollow shaft rotatably assembled on the axle. A power transmission device for four-wheel drive vehicles.
