Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to an automobile shock absorber with damping. Background Art

[0002] Automobile shock absorbers are one of the important components in the automobile suspension system, which are used to reduce the vibration and bumps of the vehicle during driving and improve the stability and comfort of driving. The background of automobile shock absorbers stems from people's increasing requirements for automobile driving stability and comfort, as well as the need to improve automobile safety performance. The development of automobile shock absorbers can be traced back to the early 20th century. The original automobile shock absorbers were mainly mechanical, using a combination of springs and dampers to reduce vehicle bumps. In the 1950s and 1960s, with the development of hydraulic technology, hydraulic shock absorbers began to be widely used in the field of automobile manufacturing. Later, with the continuous development of electronic technology, electronic shock absorbers also began to gradually become popular, which further improved the stability and comfort of automobile driving. Now, automobile shock absorbers have become an important part of the automobile suspension system. The types and technologies of shock absorbers of different car brands and models are also constantly developing and upgrading. For example, the adaptive shock absorbers used in some high-end cars can automatically adjust the damping of the shock absorber according to road conditions and driving behavior, thereby improving driving stability and comfort. In general, the background of automobile shock absorbers is the automotive industry's continuous pursuit and improvement of product performance and technology, and it also reflects people's increasing demand for driving comfort and safety.

[0003] However, the automobile shock absorber in the prior art still has the following disadvantages:

[0004] 1. Some automobile shock absorbers in the prior art still use a telescopic rod spring for shock absorption, which leads to poor shock absorption effect. The shock absorption performance is unstable: the shock absorption performance of the telescopic rod spring shock absorber is easily affected by the external environment and working conditions. For example, when encountering strong winds, weak road reaction, etc., the shock absorption effect is reduced, and even rebound will occur. Inconvenient to adjust: The shock absorption performance of the telescopic rod spring shock absorber is difficult to adjust. Therefore, under different road conditions and driving conditions, the shock absorber cannot be adjusted according to actual needs, and thus cannot meet the needs of different drivers. Short life: The durability of the telescopic rod spring shock absorber is relatively poor, and it is prone to fatigue and deformation, resulting in reduced shock absorption performance, which requires frequent replacement and maintenance. Impact on driving comfort: The telescopic rod spring shock absorber has poor shock absorption effect, which easily causes vehicle bumps, tremors and vibrations, affecting driving comfort and stability.

[0012] 1. The utility model has the advantages of using hydraulic oil damping for shock absorption, and has good shock absorption effect: the vibration of the vehicle can be absorbed and consumed by the flow of liquid in the damper, thereby improving the stability and comfort of the vehicle. Compared with mechanical shock absorbers, the damping force between hydraulic oil dampers changes more smoothly, and will not produce rebound and unstable shock absorption effects. Strong adjustability: The hydraulic oil damper can adjust the damping effect of the shock absorber by changing the flow resistance of the liquid inside the damper, thereby meeting the needs under different driving conditions. For example, on a highway with good road conditions, the damping force can be reduced to make the vehicle drive more smoothly, while on a mountain road with poor road conditions, the damping force can be increased to ensure driving stability. Long life: The internal structure of the hydraulic oil damper is simple, the friction loss is small, and the service life is long. At the same time, its different components can be replaced and maintained with each other, reducing the replacement and maintenance of the entire shock absorber. Wide applicability: The hydraulic oil damper can be used in cars of different models and brands, and can be adjusted and improved according to the different use environments and working requirements of the vehicle.
