There are many types of shock absorbers. Most motorcycles use cylinder shock absorbers, and only a few use leaf spring structures. There are many types and varieties of cylinder shock absorbers. Generally speaking, they are divided into front shock absorbers and rear shock absorbers according to the installation position.
(1) According to the direction of attenuation force: there are one-way shock absorbers and two-way shock absorbers.
(2) According to load adjustment type: there are spring initial pressure adjustment type, gas spring type, and installation angle adjustment type.
(3) According to the structural form: there are telescopic tube front * hydraulic shock absorbers (this is the most commonly used front shock absorber in motorcycles at present), rocker arm shock absorbers, rocker arm lever vertical center shock absorbers, and rocker arm lever inclined center shock absorbers.
(4) According to the working medium: there are spring shock absorbers, spring-air damping shock absorbers (because the damping force of air is limited, the shock absorption effect is not ideal, generally only used as rear shock absorbers for light motorcycles with low speed), hydraulic damping shock absorbers, oil-air combined front shock absorbers, and nitrogen-filled hydraulic shock absorbers.
