High-rotating-speed mechanical wheel

The invention discloses a high-rotating-speed mechanical wheel which comprises a shock absorber hinged between an inner rim and an outer rim. The piston divides the damping cavity into a first oil cavity and a second oil cavity, and the second oil cavity is located on the side close to the inner rim; the compensation hole is formed in the piston; the throttling sliding seat is provided with a circulation channel and is arranged in the second oil cavity in a sliding mode, and a throttling rod capable of extending into the compensation hole is arranged on the throttling sliding seat; the cross section area between the compensation hole and the throttling rod is of a reducing structure. In the rotating state, the higher the vehicle speed is, the stronger the centrifugal force is, the smaller the cross sectional area is, and the stronger the damping force is. Compared with the prior art, the method has the beneficial effects that by combining the damping principle and the centrifugal principle, the throttling are
