Two-speed variable speed electric vehicle rear axle reducer assembly with electromagnetic two-way clutch

Abstract

The invention discloses a two-gear variable-speed electric vehicle rear axle reducer assembly with an electromagnetic bidirectional clutch. The two-gear variable-speed electric vehicle rear axle reducer assembly with the electromagnetic bidirectional clutch comprises a reducer shell, the electromagnetic bidirectional clutch, a two-stage reduction high-low gear pair, a shift shaft assembly and a differential mechanism assembly, wherein the electromagnetic bidirectional clutch is arranged on one side of the top in the reducer shell, the electromagnetic bidirectional clutch is connected with the shift shaft assembly arranged on the other side of the top of the reducer shell, the shift shaft assembly is connected with a gear shifting mechanism, the electromagnetic bidirectional clutch is meshed with the two-stage reduction high-low gear pair arranged at the lower portion, and the two-stage reduction high-low gear pair is meshed with the differential mechanism assembly arranged at the bottom. According to the two-gear variable-speed electric vehicle rear axle reducer assembly with the electromagnetic bidirectional clutch, free shifting of high gear and low gear in the motion process is achieved, the cruising ability of an electric vehicle is improved, the operation is convenient, customers from different regions can drive on road surfaces of different conditions, gradeability and driving speed are achieved at the same time, driving mileage of the vehicle is also increased, and the application universality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle rear axles, and in particular relates to a two-speed variable-speed electric vehicle rear axle reducer assembly with an electromagnetic two-way clutch. Background technique [0002] With the rapid development of electric vehicles, electric vehicles must not only be environmentally friendly and energy-saving, but also improve the passability of complex roads and increase the climbing and battery life of the vehicle. At present, most of the electric vehicles produced and sold on the market adopt the drive rear axle in the form of two-stage deceleration. Among them, the load of the motor is relatively large, and the climbing ability is weak; when the electric vehicle slides downhill or slides freely due to inertia, the motor rotor is always inseparable from the reducer, which greatly reduces the cruising range of the electric vehicle in the process. The car's climbing ability is poor and th...

Problems solved by technology

At present, most of the electric vehicles produced and sold on the market adopt the drive rear axle in the form of two-stage deceleration. Among them, the load of the motor is relatively large, and the climbing ability is weak; when the electric vehicle slides downhill or slides freely due to inertia, the motor rotor is always inseparable from the reducer, which greatly reduces the cruising range of the electric vehicle in the process. The climbing ability of the car is poor, and the motor flange is integrated with the left / right box, which results in low battery life of the same type of rear axle and is not suitable for interchangeable installation of motors of various specifications. It is also difficult in terms of three guarantees and maintenance
