The utility model discloses a bottom of disc structure and dome shape, on the one hand, intensity and rigidity are good, and on the other hand, slope structure play the effect of buffering load, avoid bumping hard and damaging hard, improve life, and main casing structure is convenient for adopt stretch forming, need not welding process, and reduction in production cost and the technology degree of difficulty have increased qualification rate and production efficiency, and the upper and lower plane is convenient for install bottom and motor.

Description

Tricycle rear axle housing

Technical Field

The utility model belongs to the technical field of electric tricycle, a tricycle rear axle housing is related to.

Background

The tricycle rear axle is a rear driving axle component for power transmission of tricycle, in the electric tricycle the rear axle is an indispensable part, and has the functions of supporting vehicle body, connecting rear wheel and driving vehicle, and the rear axle shell is an important component of rear axle, in which several components are mounted. The external part supports the automobile body, connects the wheel, plays the middle effect of holding from top to bottom. In the practical use of tricycle, receive the influence of different road conditions, the impact load that the axle housing received to produce between wheel and ground and the influence on direct impact ground lead to the axle housing to warp the damage easily, therefore the axle housing should have sufficient intensity, rigidity and good dynamic characteristic afterwards.
