ABSTRACT:
Differential with a housing containing a pinion in the form of a bevel gear which together with a shaft section--constituting one unit with it and projecting from its wide top face--is held by bearings in the housing, whereby the shaft section may be connected and driven by a drive shaft, a crown gear which operates in conjunction with the pinion and is coupled to or constitutes one unit with a rotating satellite housing located in the housing, in which two freely rotating opposing satellites are held by bearings each of which operate in conjunction with two opposing gears which are each connected to a wheel shaft, whereby the pinion constitutes one unit with a second shaft section--projecting from the narrow top face--which is held in the housing by means of roller bearing which has an outer race installed in an opening in the housing and an inner race installed around the second shaft section, characterized by the fact that the inner race of the aforementioned roller bearing is formed by the cylindrical outer circumferential plane of a generally cap-shaped element with a bottom and a cylindrical mantle rising vertically from it, which is slid from the outside over the second shaft section so that the inside surface of the bottom of the element rests against the top face of the shaft section.
