A motor vehicle aluminum alloy hub having weight reduction sockets at the back cavity includes a wheel disc and a rim; the wheel disc includes a flange, a flange peripheral portion and spokes; the spoke includes a spoke main arm on one side close to the flange, and two spoke branch arms extend from the spoke main arm; the spoke includes a spoke weight reduction socket on one side of the back cavity, and the spoke weight reduction socket is V-shaped; the spokes include five flange peripheral portion weight reduction sockets uniformly distributed around the flange on the back of the flange peripheral portion; and the flange includes flange weight reduction sockets between bolt holes on one side of the back cavity.

A wheel plate assembly is used to solve the time-consuming problem in the conventional process for bonding a composite material to spokes of a wheel plate. The wheel plate assembly comprises a spoke portion, a connecting member, and a wheel plate body. The spoke portion is a thin shell member and defines an inner space therein. The connecting member is protrusively disposed on an outer side of the spoke portion. The wheel plate body includes a receiving space and at least one passage space intercommunicating with the receiving space. The receiving space and the at least one passage space together extend through the wheel plate body. The at least one passage space intercommunicates with the inner space.

A low-speed vehicle wheel assembly includes a rim, at least three spokes, connectors, a central bearing seat, and bearings. Outer ends of the spokes are fixedly connected to an inner side wall of the rim through the connectors, respectively. Inner ends of the spokes are fixedly connected to an outer wall of the central bearing seat. The bearings are fitted in bearing holes of the central bearing seat, respectively. Because the rim and the central bearing seat are independent components, each component can be made with an independent mold and assembled according to the diameter of the wheel. The cost of the mold is lower, and the components are more versatile.

The present invention relates to a vehicle (100), in particular a bicycle, for performing tests for a driver assistance system. The vehicle (100) has a base body (101) and at least one strut (102), which is formed to be dimensionally stable without influence of an impact force, which is generatable upon a collision of the vehicle (100) with a collision body, and is elastically deformable upon influence of the impact force. The strut (102) is connected to the base body (101) such that upon influence of the impact force the strut (102) is non-destructively detachable from the base body (101).

A carbon fiber spoke includes a carbon fiber stick having two opposite ends, wherein a first joint and a second joint are respectively mounted to the two opposite ends of the carbon fiber stick. The first joint and the second joint respectively includes a through hole longitudinally and centrally defined therein for allowing the carbon fiber stick extending therethrough. The two opposite ends of the carbon fiber stick are respectively formed with an enlarged portion and each through hole formed with an enlarged portion, wherein each enlarged portion is complementally received in the enlarged portion in the first joint/second joint to prevent the first joint and the second joint from being detached from the carbon fiber stick.

A collision testing vehicle is disclosed which can be utilized to perform testing with a driver assistance system. The collision testing vehicle includes a vehicle having a vehicle body. The vehicle is structured to be subject to an impact force during a collision with a collision body. A wheel is coupled to the vehicle body, and the wheel includes a detachable support that is configured to non-destructively detach from the wheel when subjected to the impact force.

A wheel (1) for a bicycle includes a rim element (2), a plurality of pressure spoke elements (3) and a hub element (4) made of a thermoplastic plastics material. The rim element (2) is formed in a single piece together with the pressure spoke elements (3) and together with the hub element (4). A wheel hollow body (5) includes a closed wheel wall (6) where at least the rim element (2) and the pressure spoke elements (3) are hollow, and wherein the single-piece form of the wheel (1) is produced by means of rotational moulding in a rotational moulding die that can be heated externally. The wheel further including a drive shaft for the wheel.
