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.
