Abstract

The invention discloses an electric bicycle transmission device, which comprises a center shaft, a seal ring, a retainer ring, a hall assembly and a lock end cover, wherein the seal ring, the retainer ring, the hall assembly and the lock end cover are sequentially distributed from inside to outside along the axis direction of the center shaft and movably sleeve outside the center shaft; the lock end cover and a front drive housing are in threaded lock fixation, thereby pressing and fixing the seal ring, the retainer ring and the hall assembly between the lock end cover and the front drive housing; and the center shaft is fixedly provided with speed sensing magnet steel corresponding to the hall assembly. The electric bicycle transmission device is wide in application range, so that stable transmission of the center shaft and a rear wheel of a bicycle can be ensured and the problems that a user is accidentally injured and clothes of the user are stained, and a traditional chain transmission device needs to be frequently maintained due to the fact that the traditional chain transmission device is easily broken or damaged in use are solved.

Description

technical field [0001] The present application relates to the field of electric bicycles, in particular to an electric bicycle transmission device and an electric bicycle equipped with the device. Background technique [0002] The transmission devices of existing electric bicycles are all chain-type transmissions, such as electric bicycles equipped with rear-drive hub motors. The end of the crank is attached to the pedals. In actual application, in the electric mode, the rear drive hub motor is energized to run and directly drives the rear wheel to rotate to make the vehicle move forward; in the human riding mode, the rider steps on the pedal, and the crank drives the central axis to rotate. The shell of the hub motor is driven to rotate through the chain, and the motor shell drives the rear wheel of the bicycle to rotate to make the vehicle move forward. [0003] The above-mentioned chain type transmission device has the following disadvantages: the transmission chain is ...
