Abstract
A differential gear assembly wherein at least one constant velocity universal joint is integrated within the gear housing and wherein an outer joint member of the universal joint is designed as an outer bevel gear and is axially inwardly supported relative to the differential or planetary gears of the assembly and is outwardly supported relative to the differential carrier on a radial supporting face. The inner member of the joint is supported toward the outside on a counter face of the differential cage and/or toward the inside on a corresponding part of a second constant velocity universal joint or on a special supporting ring. Support of the joint inner part may be effected either directly or indirectly by means of a ball cage or a shaft journal, and the supporting ring is particularly suitable as a central supporting element if two constant velocity universal joints are integrated into the differential gear assembly.
