- the gear housing in which the differential carrier is rotatably mounted, a coaxial to the outer joint approach, to which a standing bellows arrangement can be connected, which is mounted on a non-rotatably connected to the outer joint part shaft journals.
- the outer joint part can have a section on the opening side for fastening a co-rotating bellows arrangement.
- the differential assembly may be in the form of a bevel gear differential, with the side shaft gears and the differential gears being in the form of bevel gears.
- the differential assembly can also be designed in the form of a crown wheel differential, wherein the side shaft wheels are designed in the form of crown wheels and the differential gears in the form of spur gears.
- the crown wheel differential offers the advantage of an axially short installation space, which is particularly favorable in special applications.
- Figure 1 shows a differential assembly according to the invention with an integrated constant velocity joint in a first embodiment in longitudinal section
- Figure 2 shows a differential assembly according to the invention with an integrated constant velocity joint in a second embodiment in longitudinal section;
- the differential assembly 2 is mounted in a stationary transmission housing 3 shown only partially and used in the drive train of a motor vehicle for transmitting torque from a drive shaft, not shown, via two side shaft gears 4, 5 on each associated shaft journal 6, of which only one is shown.
- Differential arrangements with one-sided integrated Verschegelegelenk 7 are used in particular in drive trains of motor vehicles with respect to a vehicle longitudinal axis eccentrically arranged drive shaft used, as is the case for example in front-wheel drive vehicles with transversely mounted engine.
- the differential cage 8 is of multi-part design and comprises a cup-shaped first basket part 9 with a flange 12 and a lid-shaped second basket part 10 with a flange 13, wherein on the flanges a not shown here ring gear for introducing a torque in the differential assembly 2 can be attached ,
- a support member 14 is arranged, which rotates together with the differential carrier 8 about the longitudinal axis A.
- the carrier element 14 has a plurality of pins 15 with the axis of rotation A perpendicular pin axes B.
- the pins are included in radial openings 16 in the first basket part 9.
- the carrier element 14 is integrally formed and comprises two pins 15, wherein the carrier element is inserted for mounting through the radial openings 16.
- a compensating wheel 17 is rotatably supported, wherein a sliding bearing is provided as storage.
- the differential gears 17 are axially limited to the associated pin 15, wherein they are held by the teeth engagement with the side gears 4, 5 on the pin 15 axially floating.
- the first seewel- lenrad 4 and the second Sowellenrad 5 are driven.
- Differential gears and side shaft gears 4, 5 are designed in the form of bevel gears.
- the left-hand side of the two side-shaft gears has a hub 18 with internal toothing, into which a shaft journal, not shown here, can be inserted in a torque-proof manner for transmitting torque.
