Abstract
A differential for the axle drive of a motor vehicle has a cage in the interior of which the axle shaft gears are guided and on which they are supported. For absorbing the forces acting in the direction of the axle drive shafts, the cage is made of a tube section and has at least two diametrical bores for the receiving and leadthrough of the axle drive shafts. As a result, the differential can be manufactured with a reduced weight and lower cost while having a high stiffness.
Claims10
A differential for an axle drive of a motor vehicle having a differential case carrying a driving wheel, an axle bolt disposed in the differential case carrying differential gears, axle drive shafts having shaft gears constructed as bevel gears which mesh with the differential gears, wherein the differential further comprises a cage arranged in the differential case to absorb forces acting in a direction of the axle drive shafts, said bevel gears and said differential gears being mounted in said cage, wherein said cage is formed of a tube section having a wall with at least two diametrically opposed bores, each of said axle drive shafts extending through a respective one of said two bores.
A differential for an axle drive of a motor vehicle, comprising:
- a differential case carrying a driving wheel;
- an axle bolt disposed in the differential case, said axle bolt carrying differential gears;
- axle drive shafts carrying axle shaft gears which mesh with the differential gears, the axle shaft gears being constructed as bevel gears;
- a cage in which said bevel gears and said differential gears are mounted, said cage being formed of a tube section having a wall with at least two diametrically opposed bores, each of said axle drive shafts extending through a respective one of said two bores;
- and
- wherein said cage is arranged in the differential case and absorbs forces acting in a longitudinal direction of the axle drive shafts.
