Abstract

The invention belongs to the technical field of electric bicycles, and particularly relates to a centered-motor mounting mechanism of an electric bicycle. The centered-motor mounting mechanism comprises a lifting frame (2) and a driving machine (4), wherein the rear end of the lifting frame (2) is fixedly connected to the end part of a bottom fork (1) of the electric bicycle, and a notch for being fixedly connected with a shaft sleeve (3) of a center shaft is formed in the front end of the lifting frame (2); the driving machine (4) comprises a centered motor (4-1), and a tension frame (4-3) with a tension wheel (4-2), wherein the centered motor (4-1) is mounted on the lifting frame (2), and the tension frame (4-3) is fixedly connected to the edge of the centered motor (4-1); the center shaft with a wheel disc (7) is mounted on the shaft sleeve (3) of the center shaft. The centered-motor mounting mechanism disclosed by the invention has the advantages that the structure of the transmission system is compact, and the driving performance is excellent; through the adoption of the lifting frame, the connecting strength between the bicycle frame and the motor is improved, and besides, the convenience of mounting and demounting is improved.

Description

technical field [0001] The invention belongs to the technical field of electric bicycles, in particular to a middle motor installation mechanism of the electric bicycle. Background technique [0002] With the popularity of electric bicycles, their overall structural design and transmission system structure have also been greatly developed. Compared with the traditional front drive and rear drive, the mid-mounted motor has been widely used due to its advantages of low reluctance, labor saving, small size, light weight, large torque suitable for climbing, and convenient installation and maintenance. application. In the prior art, limited to the design of the structure of the central motor transmission system, the central motor does not give full play to its excellent performance, and at the same time, limited to the structural design, the entire transmission system is not easy to disassemble. Contents of the invention [0003] In order to solve the technical problems in th...
