Treadmill Front Shock Absorber 

Suspension shock due to vibration generated by the elastic element for improving vehicle ride comfort, suspension components installed in parallel with the elastic shock absorbers for vibration attenuation, automotive suspension systems are mostly used in hydraulic shock absorber device, its working principle is that when the frame (or body) and axle relative motion between the vibration occurs when the piston moves up and down inside the shock absorber, shock absorber cavity fluid from a cavity will repeatedly go through the various pores into the other chamber. At this point the hole wall and the friction between the oil and the oil of the internal friction between the molecules forming the damping force shock, vibration energy is converted into the automobile oil heat, and then absorbed by the damper emitted to the atmosphere. In the oil passage section and other factors constant, the damping force with the frame and the axle (or wheel) increase or decrease the relative speed between, and with oil viscosity related.

Shock absorber with elastic elements bear and ease the impact of the task of damping, the damping force is too large, elastic suspension will deteriorate, and even the shock absorber connector damage. Surface to be adjusted due to the elastic element and shock absorbers this contradiction.

(1) in the compression stroke (the axle and the frame close to each other), the shock absorber damping force is smaller, in order to give full play to the elasticity of the elastic member, ease the impact. At this time, the elastic member play a major role.

(2) the suspension stroke stretch (the axle and the frame away from each other), the shock absorber damping force should be large, rapidly damping.

(3) when the axle (or wheel) and the relative velocity between the axles too large, the required damper can automatically increase the fluid flow, the damping force is always kept within certain limits, to avoid excessive shock to bear loads.

In the vehicle suspension system is widely used telescopic shock absorber, and in compression and elongation stroke damping effect can be called two-way play-acting shock absorbers, as well as the use of new shock absorbers, which includes inflatable Less shock absorber adjustable shock absorbers and resistance.
