Antriebskraftverteilungsmechanismus

摘要

A driving force distribution device for distributing driving force from an engine to left and right rear wheels has: a differential case which accommodates a differential mechanism therein; an intermediate shaft which is provided parallel to an output shaft extending leftward or rightward from the differential mechanism; a speed-up mechanism which is provided to the left or right of the differential case and changes and transmits driving force input to the differential case to the output shaft via the intermediate shaft; and a clutch mechanism capable of switching between a transmitting state in which the speed-up mechanism transmits the driving force to the output shaft and a blocking state in which the transmission of the driving force is blocked. According to the driving force distribution device, cost reduction and downsizing of the driving force distribution mechanism and a housing thereof can be realized.
