The invention provides a front drive axle wheel edge speed reduction pneumatic separation device and solves a problem of abrasion of parts in an axle in a manual mode, and problems of complexity and poor automation in the prior art. The front drive axle wheel edge reduction pneumatic separation device comprises a hub, a wheel edge end cover for sealing the hub, a front drive axle head fixedly connected with an axle, an outer half axle arranged in the front drive axle head, and a planetary mechanism mounted in the hub, wherein the outer half shaft is connected with a combination sleeve througha spline, the combination sleeve is meshed with a sun gear, a sliding sleeve and a return spring adjacent to the sliding sleeve are arranged between an outer wall of the combination sleeve and an inner wall of the front drive shaft head. The front drive axle wheel edge reduction pneumatic separation device is advantaged in that mechanical abrasion and driving resistance caused when parts in the front drive axle passively rotate are automatically reduced in the whole process, driving oil consumption is reduced, the service life of the parts is prolonged, operation is convenient and easy, the automation degree is high, states can be switched at will at any time under complex road conditions, and the application range is wide.
