A vehicle includes a vehicle wheel, a vehicle frame and an adjustment mechanism configured to move the vehicle wheel relative to the vehicle frame. The adjustment mechanism includes a cam stud and a cam spacer. The cam stud extends at least partially through the vehicle frame. The cam spacer is rotationally fixed to the cam stud. Rotating the cam spacer moves the vehicle wheel relative to the vehicle frame.

Rotating the cam spacer moves the vehicle wheel relative to the vehicle frame.

A vehicle wheel includes a wheel disk, a wheel rim, and at least one connection element that connects the wheel disk to the wheel rim. The connection element is guided through a passage in the wheel rim and is joined in the wheel disk. A seal is provided to hermetically seal the passage of the wheel rim. One or more such seal is arranged between a connection region of the wheel disk and a connection region of the wheel rim, wherein the seal surrounds the connection element in a contact-free manner.

A combined wheel includes spokes, steel bushings, a rim, a metal frame, a brake disc and pins. In use, the steel bushings are installed in grooves of the spokes; the spokes are placed so that the clamping grooves are matched with the connecting blocks; the pins are installed into holes of the spokes and the connecting blocks; the metal frame is matched with the backs of the spokes; the screws I connect the metal frame, the connecting blocks and the spokes together and are matched with the steel bushings; and the brake disc is connected to the metal frame by screws II. In the combined wheel, the radial force and the axial force generated in the running process of the wheel can be counteracted on the spokes; and the brake disc brakes from the inside, thereby increasing the brake radius and reducing the clamping force required when braking.

A rim for a non-pneumatic tire comprises a cylindrical rim wall portion, and a fixing member disposed to be spaced apart from the rim wall portion in a radial direction. The rim wall portion is provided with a fixing protrusion protruding in the radial direction or a fixing groove depressed in the radial direction.

A combined wheel includes spokes, steel bushings, a rim, a brake pad, pins and a backing ring. The spokes are placed in respective empty slots between adjacent connecting blocks, and clamping grooves therein are matched with the connecting blocks. The pins are installed into holes of the spokes and the connecting blocks. A left end face of a backing ring is matched with the back of the spokes. A plurality of screws connect the backing ring, the connecting blocks and the spokes and are fitted into the steel bushings. The brake pad is fixed to two pluralities of bosses by a second plurality of screws. In use of the combined wheel, both radial force and axial force generated in the running of the wheel can be counteracted on the spokes. The annular brake pad is installed on the inner wall of the rim, thereby increasing the brake radius.

A spigot joint part of a wheel hub has a cylindrical outer peripheral surface. The wheel mounting structure includes a collared member having a collar part to be press-fitted into and fixed to the spigot joint part, which is formed at a position away from an end part of the spigot joint part by a predetermined distance to protrude outward in a radial direction of the collared member. An annular protruding part is formed on a part of an inner peripheral surface of a center hole of a wheel to protrude toward a center of the wheel. In a state where the wheel is fixed to the flange part by using hub bolts, a fitting part and the annular protruding part are spigot-fitted. In a state where the hub bolts are removed, the annular protruding part is locked by the collar part.
