A vehicle axle includes, an axle gear unit housing and axle tubes adjoining the latter. The axle gear unit housing has an opening which is surrounded by a flange. Threaded blind bore holes extend beyond the thickness of the flange into the region of the wall of the axle gear unit housing which has radially outwardly on the side of the flange facing the axle gear unit housing a wall thickening which extends annularly radially circumferentially along the flange and which is configured in a continuously annular manner or so as to form spot faces partially in the areas of the threaded blind bore holes, wherein a joint flash extends in a central plane along the axle tubes and toward the flangein the region of the axle gear unit housing and at the flange along the radially outer contour of the wall thickening.

Vehicle axle

The invention is directed to a portal axle for low-slung vehicles, comprising a portal housing' into the interiorof which is guided proceeding from an axle bracket side a drive shafton which a drive wheelis arranged so as to be fixed with respect to rotation relative to it, with intermediate wheelswhich are rotatably mounted on bearing pinsin the portal housing&#x2032; and which can be rotatably driven by the drive wheeland by means of which an output wheelwhich is arranged in the portal housing&#x2032; on an output shaft so as to be fixed with respect to rotation relative to it can be rotatably driven, this output wheelprojecting into a hub carrierwhich can be fixedly connected to the portal housing&#x2032;. The drive shaftand the output shaft extend so as to be axially offset, and a brake caliper of a disk brake is arranged radially adjacent to the portal housing&#x2032;. The portal housing&#x2032; has on its axle bracket side a mounting orificewhich can be closed by a closure part and through which the drive wheeland the intermediate wheelscan be inserted into the portal housing&#x2032;, wherein the intermediate wheelshave a larger diameter than the output wheel

Portal axle

An axle assembly for a drive device for the road wheels of a vehicle includes: a stationary housing having a housing interior at least partially filled with a lubricating liquid; axle housings connected to the stationary housing and configured to permit axles of the vehicle to pass towards the road wheels; a venting bore in one of the axle housings configured to allow pressurized air to escape from the stationary housing; and at least one rib sized and positioned in the housing interior of the stationary housing so as to prevent migration of the lubricating liquid out of the venting bore.

Axle assembly for drive device of a motor vehicle

A drive device for the road wheels of a vehicle includes a stationary housing in which a rotatably drivable differential housing having an axle differential gear unit is rotatably mounted by differential bearings, at least one driveshaft being rotatably drivable by the differential housing. At least one driving gear wheel is arranged on the at least one driveshaft so as to be fixed with respect to rotation relative to the latter. The at least one driving gear wheel meshingly engage by oppositely directed helical teeth with at least one driven gear wheel for driving road wheels of the vehicle and generating axial forces directed toward the center of the axle differential gear unit. At least one thrust bearing arrangement is supported axially with respect to the at least one driveshaft at a radial supporting surface.
