Electric tricycle rear axle with buffer function

Abstract

The invention discloses an electric tricycle rear axle with a buffer function. The rear axle comprises a shaft casing pipe, a differential package mounted in the middle of the shaft casing pipe, a reducer casing and a motor, wherein the reducer casing and the motor are mounted behind the differential package in sequence, an output shaft is arranged in the shaft casing pipe, the two ends of the output shaft are movably connected with wheel discs, and the rear axle is characterized in that circular-ring-shaped elastic buffer discs are movably sleeved between the wheel discs and the shaft casingpipe, multiple hollow buffer packages are arranged on the ends, close to the wheel discs, of the buffer discs, the ends, close to the shaft casing pipe, of the buffer discs are evenly provided with multiple elastic columns, the shaft casing pipe is correspondingly provided with multiple buffer grooves matched with the elastic columns, the ends, away from the buffer discs, of the elastic columns are connected to the bottom walls of the buffer grooves through springs. Through devices such as the hollow buffer packages, the elastic buffer columns and the like, the wheel discs and the output shaftcan be effectively buffered and protected.

Description

technical field [0001] The invention relates to a rear axle of an electric tricycle with a buffer function, and belongs to the technical field of the rear axle of an electric tricycle. Background technique [0002] Electric tricycle is a relatively common means of transportation, and a rear axle is connected between the rear wheels of the electric tricycle, and the rear axle supports and drives the two rear wheels. The existing electric tricycle rear axle, when the rear wheels In the event of an impact, the rear axle has no buffer structure, causing the rear wheel discs and axles in the rear axle to break easily. [0003] Chinese patent CN 208392996 U discloses a rear axle of an electric tricycle with a buffer function and is convenient for oiling. By arranging structures such as buffer discs, balls, buffer rods, springs, and buffer grooves, the rear axle of the electric tricycle can use the buffer during use. The buffering effect of the disc can protect the output shaft an...

AI Technical Summary

Problems solved by technology

But, there is following problem in this electric tricycle rear axle: 1, when wheel disc is bumped and hits the instant of buffer plate, wheel disc can be hit by ball on the buffer plate, causes the partial damage of wheel disc; Devices such as grooves and springs realize the buffering effect of the buffer plate, and it is easy to affect the buffering effect because the buffer rod is not inserted into the buffer groove in time or reset in time
