Title:
駆動動力分配装置を制御する自動車用差動歯車装置統合体
Document Type and Number:
Japanese Patent JP2008531957
Kind Code:
A
Abstract:
A differential gear unit for motor vehicles comprises a housing and, therein, a differential gear mechanism (8), two coaxial gear mechanisms and two controllable friction clutches, the coaxial gear mechanisms transmitting an additional torque to one or other axle shaft according to the degree of engagement of the friction clutches. In order for it also to be possible for very high forces to be absorbed in long-term operation with very low installation space and wear, the coaxial gear mechanisms have in each case one internal gear which is connected fixedly in terms of rotation to one side of the associated friction clutch, and one sun gear which is connected fixedly in terms of rotation to the respective output element, and the second element of each coaxial gear mechanism is a sun gear, and a third element is configured as an annular gear which has an external toothing system which meshes with the first element and an internal toothing system which meshes with the second element.
