Product Description

The main structure and working principle of HDAG shock absorber
In the suspension system, the elastic elements vibrate due to the impact. In order to improve the ride comfort of the car, shock absorbers are installed in parallel with the elastic elements in the suspension. In order to attenuate the vibration, the shock absorbers used in the automobile suspension system are mostly hydraulic shock. The working principle of the shock absorber is that when the frame (or body) and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber chamber repeatedly passes through different chambers from one chamber to the other. The pores flow into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into heat energy of the oil, which is then absorbed by the shock absorber and released into the atmosphere. When the oil passage section and other factors are constant, the damping force increases or decreases with the relative movement speed between the frame and the axle (or wheel), and is related to the viscosity of the oil.
HDAG Shock absorbers and elastic elements undertake the task of buffering shocks and damping vibrations. If the damping force is too large, the elasticity of the suspension will deteriorate, and even the connecting parts of the shock absorber will be damaged. Because of the contradiction between the elastic element and the auto shock absorber to be adjusted.
(1) In the compression stroke (the axle and the frame are close to each other), the damping force of the car shock absorber is small so as to give full play to the elastic effect of the elastic element and ease the impact. At this time, the elastic element plays a major role.
(2) During the extension stroke of the suspension (the axle and the frame are far away from each other), the damping force of the shock absorber should be large, and the vibration should be quickly reduced.
(3) When the relative speed between the axle (or wheel) and the axle is too large, the shock absorber is required to automatically increase the fluid flow, so that the damping force is always kept within a certain limit, so as to avoid excessive impact load.
Cartridge shock absorbers are widely used in automobile suspension systems, and they can absorb shocks in both compression and extension strokes, called double-acting shock absorbers. There are also new shock absorbers, which include gas-filled Shock and resistance adjustable shock absorbers.
Description of the working principle of the double-acting cylinder shock absorber.
During the compression stroke, it means that the wheel of the car moves closer to the body, the shock absorber is compressed, and the piston in the shock absorber moves downward at this time. The volume of the lower chamber of the piston decreases, the oil pressure rises, and the oil flows through the flow valve to the chamber (upper chamber) above the piston. The upper chamber is occupied by the piston rod, so the increased volume of the upper chamber is smaller than the reduced volume of the lower chamber, and a part of the oil will push the compression valve open and flow back to the oil storage cylinder. The saving of oil by these valves creates a damping force for the compression movement of the suspension. When the shock absorber is in the extension stroke, the wheel is equivalent to being far away from the vehicle body, and the shock absorber is stretched. At this time, the piston of the shock absorber moves upward. The oil pressure in the upper chamber of the piston rises, the flow valve is closed, and the oil in the upper chamber pushes the expansion valve to flow into the lower chamber. Due to the existence of the piston rod, the oil flowing from the upper chamber is not enough to fill the increased volume of the lower chamber, which mainly makes the lower chamber generate a vacuum degree. At this time, the oil in the oil storage cylinder pushes the compensation valve to flow into the lower chamber for further Replenish. Due to the throttling action of these valves, the suspension acts as a damper when it is extended.
Since the spring stiffness and pre-tightening force of the extension valve are designed to be greater than those of the compression valve, under the same pressure, the sum of the channel loading areas of the extension valve and the corresponding normally open gap is smaller than the sum of the channel cross-sectional areas of the compression valve and the corresponding normally open gap. This makes the damping force generated by the extension stroke of the shock absorber greater than the damping force of the compression stroke, which meets the requirement of rapid vibration reduction.
