Embodiment Construction

[0044] figure 1 A schematic side elevational view of a drive train of a bicycle or electric bicycle with a rear wheel drive according to an embodiment of the invention is shown. Such as figure 1 As shown, the rear wheel transmission mechanism is arranged on the power train of a bicycle or an electric bicycle. The drive train may generally include a pair of pedals 51 , a pair of crank arms 50 , a transmission and a rear hub 49 . Pedals 51 are rotatably mounted to free ends of the crank arms 50, respectively. The inner ends of the crank arms 50 are respectively fixed to opposite ends of the crank shaft 5 of the transmission. For the drive train of a bicycle or an electric bicycle, the pedaling force acting on the pedal 51 is transmitted to the rear hub 49 via a drive path. Wherein, the transmission path is from the crank arm 50 to the transmission device, and then to the rear hub 49 . The rear hub 49 may be coupled to a hub or motor 48 to rotate the rear wheel of the bicycl...

Abstract

A rear wheel transmission mechanism of a bicycle or an electric bicycle includes a rear driving gear assembly including a rear driving gear having a ratchet cavity for setting ratchets therein; and arear driving gear assembly having a ratchet cavity for setting ratchets therein. A pawl seat disposed in the ratchet cavity; A limiting assembly for fixing the pawl seat in the ratchet cavity; A pawlmember disposed within the pawl seat and configured to selectively enter or disengage the ratchet wheel such that the ratchet wheel selectively drives or does not drive the rear drive gear to rotate.As that scheme of the invention is reasonably design, the rear driven teeth are directly connected with the flower drum or the motor through the spline shaft, and the structure is simple, and the precision requirement of the flower drum is not high, so that the assembly time is reduce, and the processing cost is greatly reduced.

Description

technical field [0001] The invention relates to a transmission system of a bicycle or an electric bicycle, in particular to a rear wheel transmission mechanism of a bicycle or an electric bicycle. Background technique [0002] Although the shared bicycles and electric vehicles that have appeared in the past two years have met the travel requirements of the public, most of their transmission methods still use sprocket and chain transmission. Although this transmission structure is equipped with a chain baffle, it is still an open transmission structure, and the rider's trousers or skirt are easily entangled or bitten by the chain or sprocket, which may even cause the rider to fall and cause property or personal injury . Simultaneously, because the chain material is fatigued and stretched for a long time, it is easy to break or fall off after a period of use, requiring re-maintenance or installation, which brings a lot of troubles to the cyclist. Electric bicycle also has ab...
