A vehicle wheel end assembly comprising a wheel hub, rotatably mounted on a wheel axle spindle by a wheel bearing s comprising a roller bearing. The wheel bearing has a bearing inner ring mounted on an external section of the wheel axle spindle and a bearing outer ring mounted in an internal section of the wheel hub. The assembly further comprises a threaded hub nut mounted at the end of the wheel axle spindle to fix the bearing inner ring on the wheel axle spindle and a rotational lock mechanism to prevent relative rotation between the bearing inner ring and the wheel axle spindle. The rotational lock mechanism comprises a tangential surface arranged to intersect a part of an inner circumference of the bearing inner ring at right angles to the axis of rotation in a plane located at or adjacent an outer radial end surface of the bearing inner ring.

The invention relates to a wheel end assembly for a vehicle, comprising a central wheel support member such as a spindle or a steering knuckle, and an outboard wheel end bearing arranged concentrically around the central wheel support member. The outboard wheel end bearing comprises roller elements accommodated between an inner race-forming part and an outer race-forming part surrounding the inner race-forming part. The inner race-forming part is configured to be supported by the central wheel support member. The central wheel support member comprises a first rotational lock portion. The inner race-forming part comprises a second rotational lock portion configured to engage with the first rotational lock portion to prevent the inner race-forming part from rotating relative to the central wheel support member. The invention also relates to a vehicle comprising such a wheel end assembly.

A wheel bearing assembly for trucks includes a brake element and a wheel adapter defining a rotating component, an axle element defining a stationary component, and a multi-row, preferably double-row, bearing unit. The bearing unit has a first bearing ring, a second bearing ring and a plurality of rolling elements disposed between the first and the second bearing ring. The first bearing ring is connected to a drive shaft, the second bearing ring is connected to the axle element and the wheel adapter is configured to connect the first bearing ring to the wheel and the brake element. A shield is disposed between the brake element and the first bearing ring and/or disposed between the brake element and the axle element and is configured to shield a space defined by the first bearing ring, the wheel adapter and the brake element from entry of particles and/or water.

The present invention resides in a sensorized roller of a roller bearing. The sensorized roller includes a roller bore that accommodates a measuring device for measuring deformation of the roller bore and electronics for processing a deformation signal from the measuring device and wirelessly transmitting the processed deformation signal to an external receiver. According to the invention, the measuring device and electronics are mounted in a rigid housing that is shaped to fit within the roller bore. A radially outer surface of the housing includes at least one aperture associated with the measuring device. Furthermore, the rigid housing is resiliently mounted to the roller bore via first and second sealing elements that enclose a radial gap between a radially inner surface of the roller bore and a radially outer surface of the housing.

A vehicle may include a flutter resistant caster. The vehicle may include a frame, a drive wheel coupled to the frame, a caster housing coupled to the frame, a caster, a locking element, a first bearing, and a biasing element. The caster housing may include an opening. The caster may include a caster wheel and a caster stem extending through the opening in the caster housing. The caster stem may be configured to rotate relative to the caster housing. The locking element may be coupled to the caster stem. The first bearing may be coupled to the caster stem. The biasing element may be coupled to the caster stem. The biasing element may be configured to exert a force on the first bearing.

A lock for use with an assembly is provided. The assembly includes an inner race having a bore with a generally tapered periphery. The bearing assembly supports a shaft. The bearing lock includes a sleeve having a generally cylindrical internal periphery adapted for cooperation with the shaft and a generally tapered external periphery that cooperates with the bore. The sleeve conforms from a first condition whereby the internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter different than the first. The bearing lock also includes a collar that cooperates with the sleeve to urge the sleeve from the first condition to the second condition. The collar conforms from a first condition whereby the generally cylindrical internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter substantially different than the first.

A cage segment for a rolling bearing delimiting a plurality of through pockets for receiving rollers and having first and second walls extending in the circumferential direction and provided with internal surfaces opposite one another and forming abutment surfaces for the end faces of the rollers, and a plurality of beams extending transversely between the first and second walls and linking the walls, each pocket being delimited in the circumferential direction by two successive beams and each beam partly delimiting two successive pockets. Each beam includes, at a lateral end, a protuberance of concave outer form and intended to come into contact with the outer surface of at least one roller, two protuberances being opposite in the circumferential direction for each through pocket.
