駆動伝達装置。 A first output shaft that transmits rotation to a wheel that is always driven among the front wheels and rear wheels, and a second output shaft that transmits rotation to a wheel that is driven only during four-wheel drive.
Front and rear wheels of a part-time four-wheel drive vehicle, comprising an output shaft and a sprocket arranged on the axis of the second output shaft and to which rotational force is transmitted from the first output shaft through a two-wheel/four-wheel switching mechanism. A drive transmission device, wherein an inner rotor is rotatably assembled to a crank portion eccentric from the rotation axis of the second output shaft on the axis of the second output shaft, and the inner rotor is installed in a pump chamber formed on the sprocket side. The hydraulic chambers partitioned by the inner rotor in this pump chamber are communicated with each other by oil passages, and the oil passages are arranged so that the hydraulic pressure acting thereon exceeds a predetermined value. A front and rear wheel drive transmission device for a part-time four-wheel drive vehicle, which is equipped with a normally closed check valve that opens when the vehicle is turned off.
