Abstract

The invention discloses a two-shaped three-stage deceleration middle torque transmission system. The two-shaped three-stage deceleration middle torque transmission system comprises a stator, a rotor, a motor shaft, a torque sensing device and a gear disc, wherein the torque sensing device comprises a middle shaft, an elastic connector, a shaft sleeve and a sensor; the motor shaft is provided with a first-stage transmission gear; the motor shaft is provided with a second-stage transmission gear, a first toothless flying wheel and a third-stage input gear which are concentrically fixed through bearings in a supporting way; the shaft sleeve is respectively provided with a duplicate gear and a third-stage output gear through bearings in the supporting way; the duplicate gear is respectively meshed with the first-stage transmission gear and the second-stage transmission gear; the third-stage output gear is meshed with the third-stage input gear; an output flange of the outer side end of the third-stage output gear is connected with the gear disc together through a second toothless flying wheel to form an output end; the output end of the elastic connector is rotationally connected with the second toothless flying wheel through a small flange so as to realize the synchronization of the elastic connector and the gear disc. According to the two-shaped three-stage deceleration middle torque transmission system disclosed by the invention, a two-shaft three-stage deceleration design is adopted, the deceleration ratio is high, the size is small, and the assembly is convenient.

Description

technical field [0001] The invention belongs to the field of electric bicycles, and in particular relates to a two-axis three-stage deceleration center torque transmission system. Background technique [0002] Electric bicycle (motorized bicycle / electric bicycle), commonly known as electric vehicle, battery car, is a kind of transportation with battery as the main energy source. Its appearance is similar to bicycles and motorcycles, and generally has pedals and chains. , can use manpower as auxiliary power. Most of the center torque transmission systems of existing electric bicycles adopt two-stage deceleration, the deceleration ratio is low, and the space size is large. Contents of the invention [0003] The purpose of the present invention is to provide a two-axis three-stage deceleration center torque transmission system, which adopts a two-axis three-stage deceleration design. While the reduction ratio is high, the space size is reduced, the error accumulation is redu...
