Problems solved by technology

[0003] The characteristics of the positive front shock absorber are: relatively simple structure, easy maintenance and disassembly, and relatively low cost; but the strength of the positive front shock absorber is relatively low (the inner tube of the precision steel pipe on the upper part of the shock absorber is turned After the connecting plate is clamped, it is easy to pinch and fatigue fracture at the clamping part, and the cast outer tube is prone to fracture under the action of external force
), the unsprung mass of the shock absorber is relatively heavy (the response is relatively less sensitive);
[0004] However, the front shock absorber of the scooter has a short installation length (generally less than 500mm, and the installation length of the front suspension of the riding bicycle is generally more than 650mm), and the inner and outer diameters of the inner tube are small (generally less than or equal to 31mm), so it is difficult to design. Inverted front shock absorber, so inverted front shock absorber has not been able to be used on scooters

Abstract

The invention discloses an inverted front shock absorber. The inverted front shock absorber comprises an outer cylinder, an inner cylinder and a bottom cylinder, the two ends of the inner cylinder arearranged in the outer cylinder and the bottom cylinder respectively in a sleeved mode, one end of the inner cylinder is connected with the outer cylinder in a sliding mode, the other end of the innercylinder is connected with the bottom cylinder through a sealing base, one end, away from the inner cylinder, of the outer cylinder is provided with an end cover; the inverted front shock absorber further comprises a connecting rod and a damping cylinder, the damping cylinder is arranged in the inner cylinder in a sleeved mode, one end of the damping cylinder is connected with the sealing base, the other end of the damping cylinder is provided with a sealing guide sleeve, a damper and hydraulic oil are arranged in the damping cylinder, the connecting rod is arranged in the outer cylinder, oneend of the connecting rod is connected with the end cover, the other end of the connecting rod penetrates through the sealing guide sleeve and then is connected with a piston rod of the damper, a spring is arranged on the connecting rod between the inner cylinder and the end cover in a sleeved mode, a spring guide sleeve sleeving the connecting rod is arranged on the inner side of the spring, oneend of the spring guide sleeve is connected with the end cover, and the other end of the spring guide sleeve extends into the inner cylinder. The inverted front shock absorber is high in strength, good in indicator characteristic and light in spring lower weight and is more flexible.

Description

technical field [0001] The application relates to the field of shock absorbers, in particular to an inverted front shock absorber. Background technique [0002] At present, motorcycle shock absorbers generally adopt hydraulic telescopic cylinder shock absorbers. According to the loading position of the outer tube, it can be divided into a positive front shock absorber and an inverted front shock absorber; the outer tube of the positive front shock absorber is installed at the lower part of the shock absorber and is connected to the wheel axle; The outer tube of the inverted front shock absorber is installed on the top of the shock absorber and is connected with the steering link plate of the motorcycle. The front shock absorber of motorcycle is mainly composed of outer tube, inner tube, piston rod, shock absorbing spring, hydraulic oil and so on. At present, the front shock absorbers of pedal motorcycles or pedal electric vehicles all adopt positive shock absorbers, while ...
