Know more about suspension shock

Detailed structural principle automotive shock absorbers
Each car suspension shock absorber mentioned, I always give the example mentioned above, so far, most people also believe that after the rebound to go through several iterations in order to stabilize the body, so that the effect of the shock absorber It is good. In fact this is wrong, when we release the pressure of the body and, in the spring force the body to rebound after rebound stabilized shock absorber effect is good. why?
Automotive shock absorbers must first find out what role? Some people will say, of course, play a cushioning effect. Shock absorber damping member asked to what? You may answer, of course is to give the body damping. In fact, to the shock absorber damping spring, look at the following diagram to understand!
Automobile suspension shock absorbers and springs combined installation diagram

Automobile suspension shock absorbers and springs combined installation diagram
In the automotive suspension, shock absorbers and springs are always used in conjunction with, when we pressed the corner of the body, the actual compression of the spring, and the corresponding arm swung. When the body is released, the spring force the body to rebound, this time to play the shock absorber spring rebound damping action, that is, after the rebound stabilized. If no shock absorbers, spring will be compressed again after a rebound bounced, showed a rebound after several body stabilized. So the shock absorbers for automotive suspension springs played a role in damping the rebound.
Shock absorber Chart
Shock absorbers Chart
Automobile hydraulic shock absorber inside filled shock absorbers for oil, the internal cylinder is divided into two: storage tank and cylinder, and the piston into the cylinder upper chamber and a lower chamber. It has done on the piston valve and circulation valve for controlling the flow of fluid between the upper chamber and a lower chamber; and compression valve and compensating valve cylinder lower chamber and storage tanks for oil between the lower chamber and the reservoir flow between the cylinders.

Shock absorber is compressed state diagram
When the shock absorber is compressed, the piston down, the chamber volume increases, the lower chamber volume decreases, circulation valve is opened, the lower chamber of the oil into the upper chamber through the flow valve; at the same time part of the compression valve to open the oil into the storage tanks. Both throttling valve on the oil shock absorber compression damping effect during exercise.
When the shock absorber is extended, the piston up, the chamber volume decreases and lower chamber volume increases, stretching the valve is opened, the upper chamber of the oil into the inferior vena done through a valve; at the same time part of the compensation for oil open into the storage tanks lower chamber. Both throttling valve on the oil shock absorber damping effect of stretching exercise.


Shock absorbers is done when the state diagram
Since the valve spring stretching force is greater than the flow of the valve and the valve hole stretch flow area less than the flow of the valve, which makes the damping force of the shock absorber done stroke is greater than the compression stroke damping force, to achieve a rapid decline of the spring shock bombs requirements.
