Abstract
A wheel rotation speed measurement assembly and a wheel hub driving system. The assembly includes a wheel hub bearer, a synchronous shaft and a compiler. The wheel hub bearer has a central shaft and an outer ring. The central shaft is hollow with an inner cavity and forms a torsion-resistant connection with a vehicle suspension. The outer ring can be driven to rotate relative to the central shaft, and forms a torsion-resistant connection with the wheel hub. The synchronous shaft is arranged in the inner cavity and has an end that is close to the first end has a torsion-resistant connection with the outer ring. The compiler is mounted at an end of the synchronous shaft away from the first end. The assembly has a simple structure and can measure the wheel rotation speed directly. Rotation speed output by this compact wheel hub driving system can be accurately measured.
