Inflation damping continuous adjusting current transformation vibration damper

Abstract

An electro-rheologic vibration absorber with damping continuously adjustable function in air charging type is prepared as embedding columnar electro-rheologic spring and compressing valve as well as drawing valve in piston of said absorber, setting oil channel on piston to let hydraulic oil flow in reciprocation way, using float piston to divide cylinder to be two parts of up oil chamber and down air chamber, setting piston rod to be hollow structure being used to pass wire to be connected with electro-rheologic spring and charging electro-rheologic fluid with apparent viscosity being controlled by externally exerted magnetic field in said spring.

Description

technical field [0001] The patent of the present invention is a new air-filled damping continuously adjustable electrorheological shock absorber. It can be used in semi-active suspension control of various wheeled vehicles and tracked vehicles. Background technique [0002] The suspension device of a vehicle is a general term for all parts and components connected between the body and the wheels. It is mainly composed of three parts: springs (such as leaf springs, coil springs, torsion bars, etc.), shock absorbers and guiding mechanisms. When the vehicle is driven on different roads and the wheels are randomly excited, since the suspension device realizes the elastic support between the vehicle body and the wheels, the dynamic load and vibration of the vehicle body and the wheels are effectively suppressed and reduced, thereby ensuring the vehicle Driving smoothness and handling stability, to achieve the purpose of increasing the average driving speed. The ride comfort and...

AI Technical Summary

Problems solved by technology

The main problem of this type of shock absorber is that the structure of the throttle valve is complicated and the manufacturing cost is high; (2) Viscosity adjustment of the shock absorber liquid: use a new type of functional material electrorheological or magnetorheological fluid with continuously controllable viscosity as the shock absorber fluid , so as to realize the stepless change of damping. Under the action of an external electric (magnetic) field, the properties of the rheological material (such as shear strength, apparent viscosity, etc.) of the electric (magnetic) rheological fluid will change significantly. The (magnetic) rheological fluid is loaded into the shock absorber and an electric (magnetic) field is applied between the inner and outer cylinders (the shock absorber piston) to change the viscosity of the electric (magnetic) rheological liquid by changing the strength of the electric (magnetic) field. Thereby changing the damping force of the shock absorber
