Problems solved by technology

[0003] Most of the existing shock absorbers use the piston to compress the medium oil in the piston cylinder to absorb energy, or set a damping hole on the surface of the piston, and convert kinetic energy into internal energy through the friction between the medium oil and the damping hole to achieve damping. For the effect of shock absorption, because the medium oil and the piston are involved inside, the number of internal components increases, and the machining accuracy of the piston is high, and in order to avoid the leakage of the medium oil, the oil storage chamber also needs to be sealed, resulting in an increase in the overall production cost. And in the process of use, due to the aging of the seal of the oil storage chamber, the problem of medium oil leakage will occur, resulting in a decrease in the damping effect and affecting the comfort of the vehicle

Abstract

The invention discloses a rear axle damping shock absorber of an electric tricycle. The shock absorber comprises a first sleeve and a second sleeve which are coaxially sleeved. The first sleeve comprises an inner pipe and an outer pipe which are coaxially and fixedly arranged; an inner diameter of the second sleeve is not smaller than an outer diameter of the inner pipe; and the outer diameter ofthe second sleeve is not larger than the inner diameter of the outer pipe, a friction sleeve is fixedly arranged on the inner wall of the second sleeve, and the inner wall of the friction sleeve is ininterference fit with the outer wall of the inner pipe. According to the rear axle damping shock absorber of the electric tricycle, internal components are effectively reduced, production cost is reduced, and a problem of medium oil leakage is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electric tricycle rear axle damping shock absorbers, in particular to an electric tricycle rear axle damping shock absorber. Background technique [0002] In the production process of existing electric vehicles or automobiles, in order to eliminate the riding discomfort caused by the excessive shaking of the plate suspension or spring, an electric tricycle rear axle damping shock absorber will be added between the carrier frame and the wheel mounting seat to restrain the plate suspension or spring. The excessive jump of the car can eliminate the feeling of bumps on the road and improve the comfort of the ride. [0003] Most of the existing shock absorbers use the piston to compress the medium oil in the piston cylinder to absorb energy, or set a damping hole on the surface of the piston, and convert kinetic energy into internal energy through the friction between the medium oil and the damping hole to ach...
