Three-spring type shock absorber

Abstract

The invention relates to the technical field of vehicles, in particular to a three-spring type shock absorber which comprises a shock absorber body provided with a cylinder barrel. A first sliding bracket check block, a first spring sliding bracket, a second rubber buffer block, a second sliding bracket check block, a second spring sliding bracket, a third rubber buffer block and a spring lower support are sequentially arranged outside the cylinder barrel from top to bottom, a piston rod is arranged on the shock absorber body, and a piston is installed at the end, located in the cylinder barrel, of the piston rod. A spring upper support is installed at the other end, located outside the cylinder barrel, of the piston rod, a first rubber buffer block is arranged below the spring upper support, a high-rigidity spring is installed between the spring upper support and a first spring sliding bracket, and a medium-rigidity spring is installed between the first spring sliding bracket and a second spring sliding bracket. The low-rigidity spring is installed between the second spring sliding bracket and the spring lower support. The three-spring type shock absorber is compact in structure and reliable in performance, and the comfort of passengers and drivers under all road conditions is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle components, in particular to a three-spring type shock absorber. Background technique [0002] Suspension is a very important assembly in the vehicle. In the suspension structure, the shock absorber is an important component that determines the performance of the suspension. This is because the suspension must not only meet the comfort requirements of the vehicle, but also meet the its handling stability requirements. [0003] In the standard configuration, the vehicle's damping system is composed of elastic elements and dampers. In the field of vehicles such as passenger cars, low-speed four-wheeled vehicles, motorcycles, electric vehicles, and tricycles, coil spring-type elastic elements have become the mainstream, and coil springs and shock absorbers are combined into one component. It is not used to support the weight of the body, but to suppress the shock of the spring and absorb the energy...

Problems solved by technology

Without a shock absorber, it will be impossible to control the back and forth bounce of the vehicle suspension spring. When the vehicle encounters a rough road, it will have serious bounce. When the vehicle is cornering, the vibration of the suspension spring will also cause tire grip and tracking. loss of sex

[0004] At present, single-spring shock absorbers are the main ones on the market, and double-spring shock absorbers are supplemented. From the perspective of performance and functional performance, each has its own advantages and disadvantages, because the stiffness of the existing single-spring shock absorbers is either too hard or too soft. , the ride experience is not strong. Although the existing double spring shock absorber combines soft and hard springs, the stiffness change is not soft enough, and the ride experience still has room for improvement.

When the driving road conditions are different, due to the influence of the spring characteristics and structure, the vibration reduction effect of the double spring type shock absorber is better than that of the single spring type shock absorber, but the vibration reduction effect is still not up to the ideal requirement, which affects the driving personnel. comfort, the vibration reduction effect needs to be improved when the vehicle speed is fast and the road surface is rough

No matter from the perspective of research and development or application, the existing shock absorbers have not yet made substantial breakthroughs.
