The connection also comprises a first plurality of layers of reinforcing fibers (24) extending in a generally radial direction R relative to an axis of rotation of the wheel (10), and along a front face of each spoke (18), across a front edge (26) and an inner annular surface (28) of the hub ring (22) and across a front face (30) of the hub plate (16); and a second plurality of layers of reinforcing fibers (32) extending in a generally radial direction R along a rear face (33) of each spoke (18), across a rear edge (34) of the hub ring (22) and across a rear face (36) of the hub plate (6). The connection further comprises a third plurality of layers of reinforcing fibers (36), the third plurality of layers (36) of reinforcing fibers overlaying the first and second (1) layers of reinforcing fibers (24, 32), the third plurality of layers of reinforcing fibers 36 extending in a direction between +30 degrees and +60 degrees to the radial direction R; and a fourth plurality of layers of reinforcing fibers (40), the fourth plurality of layers of reinforcing fibers (40) overlaying the first and second layers of reinforcing fibers (24, (32), the fourth plurality of layers of reinforcing fibers (40) extending in a direction (20) between 30 degrees and 60 degrees to the radial direction R.

The invention relates to a roll-up traction mat (10) for a vehicle (V) having at least one wheel (R1), said traction mat comprising a main track portion (12), and a track starter tab (20) that is fastened to one of the ends of the main track portion (12) by a hinge-forming connection portion (22) arranged to lower the track starter tab relative to the main track portion, by means of which the track starter tab can be positioned at the bottom of a rut (O) in which said wheel of the vehicle is stuck. The track starter tab comprising a plurality of transverse stiffener elements and a top face provided with studs. The track starter tab and the main track portion are constituted by at least one textile layer covered in a polymer layer.

An axle assembly having an axle housing, a wheel end cover and an axle shaft. The axle housing has a tubular member with an end flange coupled thereto. A pair of axle bearings are mounted to the axle shaft and the end flange and support the axle shaft for rotation relative to the axle housing. The wheel end cover is mounted to the end flange and carries a seal that is engaged to the axle shaft. A method for assembling an axle assembly is also provided.

A bicycle axle assembly has a nut, a main body member and an adjustment structure. The nut includes a bore having an internal thread. The main body member includes a nut bore. The nut is disposed in the nut bore. The adjustment structure adjustably couples the nut to move axially with respect to the main body member.

A bicycle rim comprises a radially outer peripheral part, a radially inner peripheral part, at least one sidewall, and at least one cover member. The at least one side wall radially extends between the radially outer peripheral part and the radially inner peripheral part. The at least one side wall comprises at least one opening. The at least one cover member covers the at least one opening, and the at least one cover member comprises a metallic material.

The invention relates to a cover for a wheel rim of a wheel, more particularly for a wheel rim of an alloy wheel for motor vehicles, wherein the wheel rim has a rim inner well, which merges into a rim inner flange that is arranged facing a motor vehicle when the wheel is mounted, and as a result, the wheel rim has an uninterrupted contoured section on the axially inner side. The invention, the rim inner flange can be sealed in the axial direction (a) by means of the cover. The invention further relates to a wheel, particularly having such a cover.

A component for a wheel hub assembly and an axle assembly comprising: a volume; a channel, the channel extending from a first side of the wheel hub to the volume; a first port, placing the channel in fluid communication with the volume; and a second port, placing the channel in fluid communication with a surface of the first side; wherein the wheel hub houses a bearing via the volume, and lubricant is applied to the volume and the bearing via the channel while the wheel hub remains assembled and physically coupled to other components of a vehicle.

A planetary wheel end includes a planetary gear set, a rotatable axle shaft, a rotationally fixed axle tube surrounding at least a portion of the axle shaft, and a planetary gear carrier arranged for fixing to a wheel. The planetary gear set includes a radially inner sun gear, a radially outer ring gear and a plurality of planet gears drivingly engaged with the sun gear and the ring gear. The axle shaft is rotationally fixed to the sun gear and the axle tube includes a spindle rotationally fixed to the ring gear. The planetary gear carrier includes a plurality of planetary shafts and each one of the planet gears is rotatable about a respective one of the planetary shafts. In an example embodiment, each one of the plurality of planet gears has a respective radial needle bearing disposed on the respective one of the plurality of planetary shafts.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.
