The Role Of Automobile Shock Absorber

Sep 06, 2017

     In suspension system, because of the vibration of the elastic element, in order to improve the ride comfort of the vehicle, in parallel with the elastic elements in the suspension and the damper, in order to attenuate the vibration, the automobile suspension system uses the damper mostly the hydraulic shock absorber, its working principle is when the frame (or the body) and the axle between the vibration appeared relative motion, The piston in the shock absorber moves up and down, and the oil in the shock absorber cavity flows from one cavity to another in a different cavity.Shock Absorber
     At this time, the friction between the Combi and the oil and the internal friction between the oil and liquid molecules form a damping force, which transforms the vibration energy of the vehicle into the oil heat, and then the absorber is absorbed into the atmosphere. When the section and other factors of the oil channel are constant, the relative movement velocity between the frame and the axle (or the wheel) is increased and the damping is related to the viscosity of the oil liquid. Shock absorber and elastic element bear the task of slow impact and vibration reduction, the damping force is too large, will make the suspension elastic deterioration, even the shock absorber connector damage. The contradiction between the elastic element and the shock absorber should be adjusted.Shock Absorber
    The damping force of the damper is smaller in the compression stroke (bridge and frame), so as to give full play to the elasticity of the elastic element and mitigate the impact. At this point, the elastic components play a major role. The damping force of the damper should be large and the vibration should be reduced rapidly during the course of the suspension (the axle and the frame are away from each other). Shock Absorber
    When the relative speed between the axle (or the wheel) and the axle is too large, it is required that the shock absorber can increase the liquid flow automatically, so that the damping always stays within a certain limit to avoid the heavy impact load. In the automotive suspension system is widely used in the cylindrical shock absorber, and in the compression and extension of the stroke can be used in the use of the two-way shock absorber, as well as the use of new shock absorber, it includes inflatable shock absorber and drag-adjustable damper.Shock Absorber
