Abstract
An automobile reverse rotation braking wheel is a mechanical device which achieves deceleration and braking by the aid of frictional reverse push effect of the pavement on the pneumatic tire after a transmission mechanism in a wheel enables a pneumatic tire to rotate reversely. The automobile reverse rotation braking wheel comprises a braking wheel casing, a conical driving wheel, a conical transmission wheel, an inner conical tire and a hydraulic push rod. When an automobile goes forward, the braking wheel casing, the conical driving wheel, the conical transmission wheel and the inner conical tire are connected to form a rotating integral by means of push of the hydraulic push rod, so that the automobile is pushed to go forward; during braking, push of the hydraulic push rod is released firstly, anticlockwise reverse rotation of a conical transmission gear is achieved under drive of a conical driving gear, and then the frictional reverse push effect of the pavement on the pneumatic tire is used, so that rotating speed of the wheel is decreased and the automobile is prevented from going forward.
