Background

The damping shock absorber for automobile is one device to provide resistance to motion and to consume motion energy. A wide variety of dampers (or shock absorbers) have long been used in the aerospace, aviation, military, firearms, automotive, and other industries to dampen vibration and dissipate energy. From the 70 s of the 20 th century, people began to gradually transfer these technologies to structural engineering of buildings, bridges, railways, etc., which developed very rapidly. In particular, hydraulic viscous dampers, which have been in the past for over fifty years, have undergone a number of experiments, rigorous scrutiny, and repeated demonstrations, particularly the lengthy process of seismic testing, before being accepted by the structural engineering community in the united states.

The patent publication No. CN201159258Y discloses a bearing type variable damping shock absorber for an automobile suspension, which comprises a double-cylinder oil cylinder with an inner cylinder and an outer cylinder, wherein an upper port of the double-cylinder oil cylinder is formed by an inner cylinder barrel and an outer cylinder barrel which are sealed by a guider and a sealing seat, a piston arranged in an inner cavity of the oil cylinder and a piston rod connected with the piston, a one-way valve arranged at the bottom of the inner cylinder barrel and communicated with the inner cavity and the outer cavity of the double-cylinder oil cylinder, a piston one-way valve arranged on the piston and communicated with an upper cavity and a lower cavity, and an air charging nozzle arranged at the lower part of the outer cylinder barrel, and is characterized in that the piston one-way valve is a common one-way valve without an orifice; the side wall of the lower part of the inner cylinder is provided with a compression damping hole communicated with the inner cavity and the outer cavity, a static seal is arranged between the sealing seat and the outer cylinder, and a high-pressure sealing ring is arranged between the sealing seat and the piston rod. The structure is between the common double-cylinder shock absorber and the hydro-pneumatic spring, and the high-pressure sealing structure is adopted, so that the shock absorber has the capacity of bearing static load. It can make the ordinary car suspension increase its bearing capacity and possess ideal non-linear characteristics.

In actual operation, the piston moves in the cylinder body, and the damping of the piston is realized through the blocking of the damping, but in the mode, the damping of the automobile damping shock absorber is not the same in various types of automobile damping shock absorbers on the market at present, the road surface strokes suitable for different automobile damping shock absorbers are different, such as SUV (sports utility vehicle) models and sedan models, the SUV models are suitable for mountain cross-country and other strokes, the sedan models are more urban strokes, the automobile can achieve the optimal damping state by installing the damping shock absorber suitable for different terrains, and the adaptation effect of the damping shock absorber is poor due to the fact that the damping of the piston cannot be adjusted, and the damping shock absorber cannot be installed in the SUV models and the sedan models at the same time.
