Abstract
A differential for the axle drive of a motor vehicle has a differential case which is made of thin-walled metal sheets and which is freed of forces caused by the bevelled gearing of the differential bevel gears and axle shaft gears. The axle shaft gears are disposed in a separate cage which absorbs the forces acting in the direction of the axle drive shafts, and the forces acting in the direction of the axle bolt are supported, for example, directly in the ring gear. As a result, the differential can be manufactured with a high stiffness while its weight and costs are reduced.
Claims20
A differential for the axle drive of a motor vehicle, comprising:
- a differential case which carries a drive gear;
- an axle bolt disposed in a recess in the differential case;
- differential bevel gears carried by the axle bolt;
- axle drive shafts and axle shaft gears arranged on the axle drive shafts, the differential bevel gears meshing with the axle shaft gears which are arranged on axle drive shafts, the axle shaft gears being bevel gears;
- and
- a cage in which the axle shaft gears are disposed and which absorbs the forces acting in a direction of the axle drive shafts.
