A car shock absorber is actually a vibration damper. shock absorbers are not only used in suspension in automobiles, but also in other positions. For example, it is used in the cab, car seat, steering wheel, etc., and it can also be used as a buffer on the bumper of the vehicle.
How do we determine if the shock absorber needs to be replaced?
What are the classifications of shock absorber by structure?
What is the function of automobile shock absorber?
1. Make the car stop after driving 10km on a road with poor road conditions, and touch the shock absorber shell with your hands. If it is not hot enough, it means that there is no resistance inside the shock absorber and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then carry out the test. If the shell is hot, it means that the shock absorber is short of oil inside, and you should add enough oil; otherwise, the shock absorber is invalid.
2. Press the bumper hard and then release it, if the car jumps 2~3 times, it means the shock absorber works well.
3. When the car is running slowly and brakes suddenly, if the car vibrates violently, it means that there is something wrong with the shock absorber.
The structure of the shock absorberis that the piston rod with the piston is inserted into the cylinder, and the cylinder is filled with oil. There is an orifice on the piston, so that the oil in the two spaces separated by the piston can complement each other. Damping is produced when viscous oil passes through the orifice, the smaller the orifice, the greater the damping force, and the greater the viscosity of the oil, the greater the damping force. If the size of the orifice remains the same, when the shock absorber works fast, excessive damping will affect the absorption of shock. Therefore, a disc-shaped leaf spring valve is set at the outlet of the orifice. When the pressure increases, the valve is pushed open, the opening of the orifice becomes larger, and the damping becomes smaller. Since the piston moves in both directions, leaf spring valves are installed on both sides of the piston, which are called compression valves and extension valves.
1. Generate damping: The shock absorber is one of the very important components in the vehicle suspension system. 2. Components: The suspension consists of a swing arm, an elastic element, and a shock-absorbing damper. When the wheels roll over the potholes, affected by the undulations of the road surface, the wheels will also move up and down with the undulations of the road surface. 3. Cushioning movement: The elastic element is used to cushion the up and down movement of the wheel. If there is no shock absorbing damper, the vehicle body will sway non-stop. This is the result that the rebound force of the elastic element cannot be converted away. 4. Absorb the rebound force: the shock absorber damper is required to provide a suitable amount of damping to absorb the body swing caused by the rebound force of the elastic element. And make the body more stable.
