description

The shock absorber is an appliance for accelerating the attenuation of the vibration of the frame and the body to improve the driving smoothness (comfort) of the car. A shock absorber is installed in the suspension system of most cars.
The hood is under the hood to provide an additional layer of protection.
Its working principle is that when the frame and the axle reciprocate and the piston reciprocates in the cylinder, the oil in the shock absorber flows back and forth between the two isolated cavities through the narrow pores on the valve. Due to the friction between the hole wall and the oil and the internal friction of the liquid molecules, the damping force is formed, which converts the mechanical energy of the vehicle body vibration into heat energy, which is absorbed by the oil and the shell, and then dispersed into the atmosphere. The damping force is related to the cross-sectional area of the oil passage, the valve spring stiffness and the oil viscosity.
When the wheel jumps up, the shock absorber is compressed, and the piston moves down relative to the cylinder, so the volume of the lower chamber of the working cylinder decreases, the oil pressure rises, and the oil flows into the upper chamber of the working cylinder through the flow valve. Since the upper cavity is occupied by a part of the space by the piston rod, the increased volume of the upper cavity is less than the reduced volume of the lower cavity, so a part of the oil pushes open the compression valve and flows back to the oil storage cylinder 5. These valves restrict the oil The damping force on the compression movement of the suspension. When the wheel falls, the shock absorber is stretched, and the piston moves up relative to the cylinder, so the oil pressure in the upper chamber of the working cylinder rises, the flow valve is closed, and the oil pushes the extension valve to flow into the lower chamber. Similarly, due to the existence of the piston rod, the oil flowing from the upper cavity into the lower cavity is not enough to fill the increased volume of the lower cavity, and a certain degree of vacuum is generated in the lower cavity. At this time, the oil in the oil storage cylinder pushes open the compensation valve and flows into the lower cavity. supplement. In this process, the throttle effect of the valve forms a damping force on the extension movement of the suspension.
