Vehicle wheel end arrangement

The brake disc arrangement () comprises a brake disc () which extends annularly about an axially extending central axis and defines an inwardly facing circumference comprising a splined portion for transferring torques between the brake disc () and a corresponding hub, when the brake disc arrangement () is mounted to the hub. The brake disc arrangement further comprises a spring assembly () adapted to be axially connected to the corresponding hub. The inwardly facing circumference of the brake disc () comprises one or more cavities (), each cavity () being defined by axially opposing lateral walls (). The spring assembly () is partially contained in said one or more cavities (), such that a portion of the spring assembly () may abut each one out of the axially opposing lateral walls ().

Brake disc arrangement for a vehicle

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub () comprising an outwardly facing gear teeth arrangement () arranged in a circumferential direction thereof; and a brake disc () comprising an inwardly facing gear teeth arrangement () arranged in meshed connection with the outwardly facing gear teeth arrangement of the wheel hub for preventing a relative circumferential movement between the brake disc and the wheel hub, wherein one of the wheel hub and the brake disc comprises a circumferentially arranged groove (); wherein the wheel brake arrangement further comprises at least one retainer () connected between the wheel hub and the brake disc for preventing a relative axial movement between the wheel hub and the brake disc, wherein the at least one retainer is at least partially arranged in the circumferentially arranged groove () of one of the wheel hub and the brake disc.

Wheel brake arrangement

A splined portion () connected to one out of a brake disc and a hub to which the brake disc is to be connected. The splined portion comprises teeth () adapted to mesh with grooves in a second splined portion () connected to the other of said brake disc and hub, and extends annularly about an axially extending central axis. At least one, preferably a plurality, of the teeth () of the splined portion () is split into at least two tooth portions () being resiliently movable towards and away from each other in a circumferential direction of the splined portion (). The splined portion () further comprises a tensioning means () adapted to releasably adjust the circumferential distance between the two tooth portions ().

Splined portion connected to one out of a brake disc and a hub

A bearing arrangement having a roller bearing having an inner race, bearing rollers, and an outer race in which the roller bearing is arranged to support a wheel hub on a wheel axle. The bearing arrangement further includes a first seal and a second seal which have been arranged on either side of the bearing rollers, wherein closed bearing spaces are delimited between the first seal and the bearing rollers, and between the second seal and the bearing rollers. The bearing arrangement is provided as a complete, sealed, preassembled unit.

Wheel bearing arrangement

The invention relates to a method for mounting rim accessories on a vehicle, the vehicle having rims with fasteners for fastening the rim to a wheel hub, the method including mounting of a bracket including at least two sections, the bracket having a first contact surface along its outer periphery for resting against an interesting contact surface on the inner periphery of the rim, the radially inner contact surface lying substantially parallel to and adjoining an axially outer edge of the rim. The method includes mounting the bracket such that adjoining end surfaces of the sections of the brackets are forced apart, thereby clamping the bracket fast to the rim, and mounting of an accessory on the bracket, the bracket having at least a second contact surface extending radially inwards along the inner periphery of the rim. The second contact surface is provided with at least two openings in each of the sections of the bracket for interaction with at least a corresponding number of fasteners on the accessory. The invention also relates to an arrangement for mounting such an accessory and a bracket intended for this purpose.
