Problems solved by technology

The above three throttle valves are all in passive mode, and the throttle characteristics of the piston cannot be adjusted according to the movement of the car. Therefore, the mechanical characteristics of the shock absorber installed with this kind of throttle valve are fixed, and the environmental adaptability is poor.

Abstract

The invention relates to a shock absorber piston structure based on a variable damping throttle valve, which comprises a piston body composed of an upper piston and a lower piston. There are two sets of variable damping throttle valves installed between them. The variable damping throttle valve includes a cylinder and a valve stem. The two ends of the cylinder are respectively provided with a base and an end cover. The magnetorheological material is sealed in the cylinder. One end of the valve stem extends into the cylinder from the end cover, and is slidably matched with the base. An iron core is fixed on the valve stem, and a coil is wound on the iron core. The other end of the valve stem is fixed with a The valve head of the damping channel, a spring is arranged between the valve head and the end cover, the valve heads of each variable damping throttle valve respectively extend into the corresponding damping channel, the valve heads of two groups of variable damping throttle valves are installed in the opposite direction. It adjusts the valve opening speed point of the piston by adjusting the electromagnetic field strength in the variable damping throttle valve, and optimizes the throttling performance of the shock absorber.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a shock absorber piston structure based on a variable damping throttle valve. Background technique [0002] The structure and characteristics of the throttle valve have a decisive influence on the characteristics of the shock absorber. At present, there are three typical valve structures of the barrel shock absorber, which are plate valve type, slide valve type and elastic valve type. Among them, the plate valve type and slide valve type are mostly used in early car shock absorbers, which are adjusted by changing the spring stiffness and the pre-deformation of the spring. Although these two valves have the advantages of simple structure and reliable operation, due to the small lift of the plate valve, a large flow area will be formed, resulting in a soft nonlinear characteristic of the velocity characteristic of the shock absorber, while the slide valve and th...
