A utility vehicle configured for traveling off-road includes: a chassis; and a drive wheel assembly coupled with the chassis and including: a drive wheel assembly rotatable portion configured for rotating and thereby for enabling the utility vehicle to traverse a ground; a hub carrier coupled with the drive wheel assembly rotatable portion, which is configured for rotating relative to the hub carrier; and an electric motor configured for causing the drive wheel assembly rotatable portion to rotate, the electric motor including a stator which is fixedly coupled with the hub carrier.

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 one-part wheel which is made of fiber composites without interruption of fibers with excellent mechanical properties and with low weight at the same time as well as a process for the manufacture thereof. The wheel has especially a rim well as well as a wheel disk passing over into a wheel flange of the rim well, where the wheel disk is formed at least partly by fiber layers, which run from the rim well over a wheel flange and the wheel disk. The wheel is manufactured by a multipart mold with parts displaceable at least in the axial direction. The mold is completely removed after the deposition of fibers or remains as a lost core in the wheel.

The invention is directed to a vehicle wheel (1) comprising a rim (2) for receiving a tire at its radially outer side (3) and provided with an edge along the circumferential of the rim at its radially inner side, a wheel hub connected to the rim via a support element, wherein the material of the rim and the support element are different, the support element provided with openings at its end facing the rim to receive a connecting element, the edge of the rim provided with openings in line with the openings of the support element and wherein the support element is connected to the rim via the connecting elements present in the openings in the edge and in the openings of the support element, wherein the opening in the edge is a radial elongated opening or is a indentation in the edge or the openings in the support element are radially elongated openings or indentations.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.

A vehicle wheel of the present invention, includes: a sub air chamber member which serves as a Helmholtz resonator and is fixed to an outer circumferential surface of a well portion in a tire air chamber; a first standing wall surface formed such as to stand from the outer circumferential surface of the well portion outward in radial direction and extend in circumferential direction of the outer circumferential surface; and a second standing wall surface formed on the well portion such as to face the first standing wall surface in width direction of the outer circumferential surface.

A wheel with a rim as well as a wheel spider, where the wheel spider has a hub and spokes. The wheel includes spokes including one or more linearly stretched textile strands as reinforcement material of a fiber composite and each linearly stretched textile strand runs at least once from the rim to the hub and back without interruption and thus forms at least one spoke. The textile strands are connected in a positive-locking manner and/or in substance with the hub and the rim. A process is provided for the manufacture of the wheel.

There is provided an automotive wheel with a cavity between the bolt holes in a hub mounting section, and more particularly, to an automotive wheel with a cavity between the bolt holes in a hub mounting section, wherein a cavity between the bolt holes in a hub mounting section structured to secure an automotive wheel to a wheel hub is uniformly formed to reduce the weight and noise of the automotive wheel, and wherein a damper rubber is inserted into the cavity to reduce the vibration and noise generated during driving an automobile.

A rim structure for a bike is revealed. It comprises a rim having two side walls, a connection wall for connecting opposite end faces of the two side walls, an inner wall for connecting the inner edges of the two side walls, and a space defined by the two side walls, the connection wall and the inner wall. The inner wall has a plurality of evenly-spaced spokes thereon, each of which has a head located inside the space. The space is filled with a foam material.
