Abstract
A transmission structure of a hub motor has a hub shell, an axle, a motor unit, and a clutch assembly. The clutch assembly connects with the hub shell and the motor unit, and includes a driving ring, an output disc, a fixing base, a clutch disc, and a pressing ring. The motor unit drives the driving ring to rotate. The output disc is capable of driving the hub shell to rotate. The driving ring drives the clutch disc to rotate and further drives the pressing ring; the pressing ring then pushes the clutch disc to contact the output disc and further drives the output disc to rotate. The fixing base is magnetic and is disposed between the output disc and the motor unit. The clutch disc is magnetically attractable such that the clutch disc separates from the output disc when the motor unit stops working to prevent the motor unit from providing resistance.
