A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

There is provided a wheel device for a vehicle including: a wheel having an opening formed between adjacent spokes; a brake mechanism located inside the wheel in a vehicle width direction and having a brake caliper and a brake rotor; and an arc portion extending in a circular direction in the opening and suspended between the adjacent spokes. The arc portion has a recessed portion recessed outward in the vehicle width direction inside thereof in the vehicle width direction, and the arc portion and the brake caliper are located at such positions that they overlap with each other in a state viewed in the vehicle width direction.

An omni-wheel may include a shaft, a plurality of rollers, and a braking device. The plurality of rollers may be circumferentially arranged about the shaft and arranged radially outward from the shaft. The braking device may include an at least one flexible clutch member, an at least one brake pad, and an actuator. The at least one flexible clutch member may have an outer diameter arranged about the shaft. The at least one brake pad may be arranged on the outer diameter of the at least one flexible clutch member. The actuator may be arranged to axially displace the at least one flexible clutch member. The at least one flexible clutch member may expand radially outward when axially displaced by the actuator, which may displace the at least one brake pad arranged on the outer diameter of the at least one flexible clutch member radially outward to contact at least one of the plurality of rollers, preventing rotation of the roller.

A vehicle axle assembly including an axle housing, carrier assembly, and first and second axle shafts. The axle housing is formed from an upper beam and a lower beam that are positioned in a clam-shell arrangement. The carrier assembly includes a carrier housing and a differential that includes a ring gear arranged in meshing engagement with a pinion. The first and second axle shafts extend outwardly from the differential in opposite directions. The pinion is rotatably supported by a self-lubricating cartridge pinion input bearing and the outboard ends of the first and second axle shafts are rotatably supported by self-lubricating and unitized grease wheel end bearings. These bearings do not require lubrication from oil contained inside the axle housing allowing for a reduced oil fill level in the axle housing, creating less viscous losses and better efficiency.

A wheel hub (10) comprises a main body (12) and a drive axle arrangement (14) extending through the main body (12). The main body (12) is rotatable about the drive axle arrangement (14). The wheel hub (10) further includes a transmission assembly comprising first and second transmission arrangements (44, 46). The first transmission arrangement (44) is provided on the drive axle arrangement (14), and the second transmission arrangement (46) is provided on the main body (12). The first transmission arrangement (44) is cooperable with the second transmission arrangement (46) to transmit a driving force from the drive axle arrangement (14) to the main body (12). The drive axle arrangement (14) comprises an axle portion (34) and a sprocket carrier (42). The axle portion (34) extends through the main body (12), and the sprocket carrier (42) is configured to carry at least one sprocket.

A steering knuckle of a utility vehicle has a main body, a steering knuckle bearing for receiving in a rotating articulated manner a vehicle axle, a hub-type, cup-shaped receiving portion, open towards a rim of a vehicle wheel, in which portion an anti-friction bearing and a bearing journal can be received. The main body has an opening for receiving a drive shaft. The opening leads into the hub-type receiving portion. An axle assembly and a vehicle axle of a utility vehicle are also provided.

A wheel module for a vehicle is disclosed including a wheel, said wheel having a wheel rim; a wheel axle, the wheel rim being rotatably mounted on said wheel axle; and a braking device for braking the wheel, said braking device comprising a brake disc and a brake pad. The brake disc and the brake pad being mutually contactable in order to transmit a braking force F1 to the wheel rim, wherein the brake disc can be axially moved to contact the brake pad and the brake pad remains axially fixed.

The vehicle power device includes: a wheel bearing including a stationary ring and a rotary ring; and a motor including a stator and a rotor. The stator and the rotor of the motor generator have a smaller diameter than that of an outer peripheral part of the brake rotor, and an entirety of the motor, excluding a mounting part to the hub flange, is located within an axial range between the hub flange and an outboard-side surface of a chassis frame component. An insulating layer is interposed between the stationary ring and the stator.

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub (102) comprising an outwardly facing gear teeth arrangement (104) arranged in a circumferential direction thereof; and a brake disc (106) comprising an inwardly facing gear teeth arrangement (108) 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 (110); wherein the wheel brake arrangement further comprises at least one retainer (112) 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 (110) of one of the wheel hub and the brake disc.

A wheel bearing arrangement for a motor vehicle, having a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier. The wheel bearing has an outer ring and an inner ring. A wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which is open in the direction facing away from the outer ring and is formed by a recess in the wheel flange and has a brake disc bearing face for a brake disc. A seal-receptacle space is formed in the wheel flange on its side facing the outer ring in an axial direction, in which seal-receptacle space there is a wheel bearing seal. A rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle.
