Loading wheel suitable for bumpy road surface

Abstract

The invention discloses a loading wheel suitable for a bumpy road surface, which relates to the technical field of wheels. The loading wheel suitable for a bumpy road surface comprises a front wheel,a front fork, rotating discs and telescopic supporting wheels. A supporting part is arranged at the bottom of the front fork; the supporting part is provided with an arc-shaped supporting plate; a through hole is formed in the center of the rotating disc; the two ends of the axle penetrate through the through holes. Rotating discs are fixed to the two side faces of the supporting ring. Sliding grooves are arrayed in the peripheral side face of the rotating disc, and the straight line where the sliding grooves are located is separated from the center of the rotating disc. The interior of the sliding groove is fixed to a telescopic device, and the telescopic device is fixedly connected with the telescopic supporting wheel; the telescopic supporting wheel comprises a pulley and a supporting rod; the pulley is fixed at the bottom of the supporting rod; a limiting supporting column is fixed to the supporting rod; the peripheral side face of the limiting supporting column is matched with thearc-shaped supporting plate. Under the action of the rotating disc and the telescopic supporting wheel, the bumping degree is greatly reduced, the comfort degree is improved, the telescopic supporting wheels and the tires on the two sides can serve as three-point supports, the contact area with the ground is increased, and sideslip is not likely to happen relatively.

Description

technical field [0001] The invention belongs to the technical field of wheels, in particular to an additional wheel suitable for potholed road surfaces. Background technique [0002] When the wheels pass through uneven roads or roads with many potholes, bumps will appear, which will cause discomfort and greatly reduce the sense of experience and comfort. Among them, the phenomenon of bumping the wheels is that when the wheels pass through the uneven road surface or the road with many potholes, the wheels will drop into the road pit under the action of gravity, and then collide with the edge of the road pit. cause turbulence. Contents of the invention [0003] The purpose of the present invention is to provide an additional wheel suitable for potholes. Under the action of the rotating disc and the telescopic support wheel, the pulley at the bottom of the telescopic support wheel at the front side where the wheel contacts the road surface will be squeezed by the road surfac...
