Abstract: 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.

Abstract: 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.
