Background
A damper or shock absorber is a device that uses damping characteristics to damp mechanical vibrations and dissipate kinetic energy. It is commonly used in suspension systems for automobiles and motorcycles, and some bicycles also have shock absorbers.
In the automobile suspension system, because the elastic element is impacted to generate vibration, in order to improve the running smoothness of an automobile, a shock absorber is arranged in the suspension in parallel with the elastic element, and in order to attenuate the vibration, most of the shock absorbers adopted in the automobile suspension system are hydraulic shock absorbers. At the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on vibration, so that the vibration energy of the automobile is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and is emitted into the atmosphere. When the cross section and other factors of the oil passage are not changed, the damping force is increased and decreased along with the relative movement speed between the vehicle frame and the vehicle axle (or the vehicle wheel) and is related to the viscosity of the oil.
The shock absorber and the elastic element undertake the tasks of buffering and shock absorption, and the over-large damping force can cause the elasticity of the suspension to be deteriorated and even cause the connecting piece of the shock absorber to be damaged. Thus, the contradiction between the elastic member and the damper is to be adjusted.
The heat decline can appear in the time of current bumper shock absorber high temperature, and the damping weakens, and damping performance significantly reduces has influenced the shock attenuation effect of bumper shock absorber, and the regulation of bumper shock absorber is through trading a relatively less damping spring of intensity, and the problem that the spring probably appears after changing soft is exactly: the service life of the shock absorber can be shortened, and the shock absorber can be in danger of scraping a chassis due to the fact that the buffer distance is increased when a road which is difficult to walk is encountered; there is a need for a shock absorbing damper that is easily adjustable and can change damping efficiency.
