Two-shift variable-speed system of inner rotor hub motor without power interrupt and electric vehicle

Abstract

The invention discloses a two-shift variable-speed system of an inner rotor hub motor without power interrupt. The two-shift variable-speed system mainly comprises an inner rotor hub motor, a first fastening screw, a speed changer annular shell, a steering joint, a second fastening screw, a speed changer right-side shell, a third fastening screw, a first electromagnetic brake, a first planetary gear train, a one-way clutch, a second electromagnetic brake, a second planetary gear train, a tyre, a rim, a rim bolt, a rim nut, a round nut, a brake disc, a brake caliper and a brake caliper fastening screw. The invention also discloses an electric vehicle. The demands of multiple aspects such as power and economy of the electric vehicle are satisfied, and the integral performance of the electricvehicle is improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a two-speed transmission system of an inner rotor hub motor without power interruption and a vehicle. Background technique [0002] The rapid development of the automobile industry has largely changed people's lifestyles and improved their quality of life. While automobiles bring many conveniences to people, they also bring many negative effects: a large amount of non-renewable energy such as oil and natural gas is consumed, a large amount of toxic and harmful gases such as carbon monoxide and nitrogen oxides, and greenhouse effect gases such as carbon dioxide are emitted, and a lot of noise is generated. etc. have brought immeasurable harm to people's living environment. Today, the energy crisis and environmental problems are becoming more and more serious worldwide, and the number of cars in the world is increasing year by year, so the above-mentioned problems will become more...

AI Technical Summary

Problems solved by technology

The purpose of the present invention is to perform shifting operation through two electromagnetic brakes and a one-way clutch, so that the driver can switch the transmission between different gears according to the actual driving conditions of the electric vehicle, and at the same time, the response speed is fast, The shifting process is completed instantly, and the power is never interrupted, and there is no shifting impact, which overcomes the technical defects of the existing electric wheel drive electric vehicle two-speed transmission with complex shifting process and poor response characteristics
