  • Differential for the axle drive of a motor vehicle and method of making same
    Patent number: 6875148
    Abstract: A differential for the axle drive of a motor vehicle, having a differential case which carries a driving wheel, is disposed in a transmission case and in which an axle bolt is disposed which carries differential gears, the differential gears meshing which axle shaft gears arranged on axle drive shafts. These gears are constructed as bevel gears. It is suggested that a first joint flange carrying a first axle shaft gear is connected by way of a connecting rod with a second joint flange carrying a second axle shaft gear, the connecting rod being guided through an opening arranged in the axle bolt. By way of the connecting rod, the two joint flanges are connected with one another in the radial direction, so that their bearing is improved.

  • Differential for the final drive of a motor vehicle
    Publication number: 20030166432
    Abstract: The invention relates to a differential for the axle drive of a motor vehicle, having a differential case (4) which carries a driving wheel (2), is disposed in a transmission case and in which an axle bolt (10) is disposed which carries differential gears (12, 14), the differential gears (12, 14) meshing which axle shaft gears (16, 18) arranged on axle drive shafts and these gears being constructed as bevel gears. It is suggested that a first joint flange (20) carrying a first axle shaft gear (16) is connected by way of a connecting rod (24) with a second joint flange (22) carrying a second axle shaft gear (18), the connecting rod (24) being guided through an opening (26) arranged in the axle bolt (10). By means of the connecting rod (24), the two joint flanges (20, 22) are connected with one another in the radial direction, so that their bearing is improved.

  • Differential for the axle drive of a motor vehicle
    Patent number: 5480360
    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.
