Abstract

The invention discloses an electric bicycle drive axle. An assistance ring, a spring and a resistance ring are also mounted on a first-level gear shaft; the assistance ring, the spring and the resistance ring are connected from left to right in sequence; limit sheets are respectively mounted on the left side and the right side of each of the assistance ring and the resistance ring; and the assistance ring and the resistance ring are in key connection with the first-level gear shaft. The electric bicycle drive axle has the beneficial effects that resistance is provided during braking, so that the braking efficiency is improved; meanwhile, the mechanical energy of an electric bicycle is changed into elastic potential energy for storage, then the elastic potential energy is released again during acceleration so as to provide power for the electric bicycle; and not only is energy saved, but also braking and accelerating efficiencies are improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle driving axle. Background technique [0002] Electric vehicle drive axles are now all designed with a reduction box installed between the motor and the gear shaft. Its main function is to increase torque, increase acceleration during the starting stage, acceleration stage, and uphill stage, and save power. However, in the process of driving, there is often a situation of accelerating first and then decelerating, especially when there is a traffic jam or when there is a red light ahead, etc., resulting in a waste of energy. Contents of the invention [0003] The purpose of the present invention is in order to solve above-mentioned problem, has designed a kind of electric vehicle driving axle. The specific design scheme is: [0004] An electric vehicle drive axle, comprising a motor and a reduction box, the motor and the reduction box are connected through a ...
