Automobile absorber recovery valve-system structure based on runway-type valve plates

Abstract

The invention discloses an automobile absorber recovery valve-system structure based on runway-type valve plates. The automobile absorber recovery valve-system structure comprises a piston rod, a piston and hex nuts. A communicating valve common washer, a communicating valve adjusting washer, a communicating valve adjustable valve seat, the communicating valve runway-type valve plate and a communicating valve multiple-groove valve plate which are arranged on the piston rod in a sleeving mode are arranged on the piston. A recovery valve communicating valve, a recovery valve adjustable valve plate, the recovery valve runway-type valve plate, a recovery valve adjusting washer and a recovery valve common washer which are arranged on the piston rod in a sleeving mode are arranged on the positions, below the piston, between the hex nuts. The automobile absorber recovery valve-system structure is of a pure valve plate structure, no spring piece exists, stability and durability of opening andclosing of all the valve plates are ensured, the runway-type valve plates are arranged in the middles of the multiple adjustable valve plates, thus change of the value of damping force nearby a valveopening point tends to be stable, the damping force becomes smooth during transition at the middle-low speed, an automobile can have good secondary smoothness while the steering response is ensured, and the automobile secondary smoothness can be effectively improved.

Description

technical field [0001] The invention relates to a shock absorber, in particular to an automobile shock absorber recovery valve train structure based on a racetrack valve plate. Background technique [0002] In most suspension systems, the shock absorbers and springs are arranged in parallel. When the vehicle is running on a bumpy road, the spring will convert the bumpy energy of the road into a sine wave form, and the main function of the shock absorber is to convert the sine wave energy into heat energy and gradually dissipate it into the atmosphere. [0003] The existing structure of the shock absorber recovery valve system is generally composed of a damping valve plate with equal diameter, a three-claw spring plate and a piston. This kind of shock absorber recovery valve system structure has poor durability when transitioning from low speed to medium speed, and the damping force value changes significantly in the middle and low speed stage of frequent use, which is refle...

Problems solved by technology

This kind of shock absorber recovery valve system structure has poor durability when transitioning from low speed to medium speed, and the damping force value changes significantly in the middle and low speed stage of frequent use, which is reflected in the poor ride comfort of the whole vehicle, and the damping valve plate is easily damaged. Stress concentration results in fracture or excessive deformation. The three-claw spring is difficult to adjust due to the limited design space, which makes the vibration of the damping valve unstable at different speeds and affects the matching and overall performance of the shock absorber. car comfort
