Abstract

A differential provided with a drive wheel comprising two pairs of bevel gears disposed in a two-part housing, one of the pairs of bevel gears being a pair of axle bevel gears and the other pair of bevel gears being a pair of compensating bevel gears.

Claims (16)

1. A differential comprising:

a two-part housing in which a pair of axle bevel gears and a pair of compensating bevel gears are rotatably mounted; and

a drive wheel comprising a flange with gearing thereon,

wherein

each of said axle bevel gears is formed integrally in one piece with a respective individual axle bevel gear shaft,

each of said compensating bevel gears is formed integrally in one piece with a respective individual compensating bevel gear shaft,

at least one of said axle bevel gears is provided with a recess in an end face opposite from the at least one axle bevel gear shaft with which the axle bevel gear is formed integrally in one piece,

at least one of the axle bevel gear shafts is provided with longitudinal teeth for connecting said at least one axle bevel gear shaft to an inner joint part of a constant velocity joint, said constant velocity joint having an outer joint part connected to a drive shaft,

at least one of said compensating bevel gear shafts is configured to provide a centering shoulder for the compensating bevel gear integrally formed with said at least one compensating bevel gear shaft,

one of the two housing parts is a differential casing provided with openings for receiving the compensating bevel gear shafts and forms directly a supporting bearing surface for one of said compensating bevel gears rotatably mounted thereon,

the flange and the gearing of the drive wheel are constructed integrally in one piece with the one of the two housing parts serving as the differential casing,

the flange comprises a hub and a plurality of spokes extending radially between the hub and the gearing, and

the one of the two housing parts serving as the differential casing is provided with recesses.

2. The differential according to claim 1 , wherein the two housing parts are joined together at a connecting surface arranged coaxially to the gearing of the drive wheel.

3. The differential according to claim 2 , wherein said connecting surface comprises a centering surface and an axial contact surface on each of the two housing parts.

4. The differential according to claim 2 , wherein the connecting surface between the two housing parts is arranged outside a mounting area of the compensating bevel gears.
