Every time he told us the shock absorber of automotive suspension.
I always give the examples mentioned above, so far, most people
also believe that in after a rebound to after a few iterations of
the body can be stabilized, such a shock absorber effect is good.
In fact this is wrong, when we press down the body and loose, in
the spring force of the body to rebound, rebound after the rebound
tends to stabilize the shock absorber effect is good. Why?
First to figure out what role the car shock absorber? Some people
would say, of course, from the shock absorption effect. And then
asked the shock absorber to what parts of the shock? You may
answer, of course, to shock the body. In fact, the shock absorber
to the spring shock, look at the following figure will understand!
In the automobile suspension, the shock absorber is always used in
conjunction with the spring, when we press down a corner of the
vehicle body, the actual compression is the spring, and the
corresponding swing arm swing. When the car is behind, in the
spring force of the body to rebound, when the shock absorber to
rebound in the spring to play a damping effect, that is, after the
rebound tends to be stable. If there is no shock absorber, the
spring will rebound again after the rebound again, the performance
of the body after a number of rebound stabilized. So the shock
absorber is the spring of the automobile suspension in the rebound
to play the role of damping shock.
The automobile hydraulic shock absorber is filled with special oil
for shock absorber. The inside is divided into two cylinders: the
reservoir and the working cylinder, and the piston divides the
working cylinder into the upper chamber and the lower cavity. On
the piston is provided with stretching valve and flow valve, used
to control cavity and a lower cavity between the oil flow; the
working cylinder chamber and an oil storage cylinder between the
compression valve and valve compensation for the oil between the
chamber and the oil storage cylinder flow.
When the shock absorber is compressed, the piston downward, the
upper chamber volume increases, the lower chamber volume decreases,
the flow valve is opened, the lower part of the oil liquid through
the flow valve into the upper chamber; at the same time a part of
the oil liquid to enter the storage cylinder compression valve.
These two valves have a damping effect on the oil flow when the
shock absorber is compressed.
When the shock absorber is elongated, the piston upward, chamber
volume decreases and volume of the inferior vena cava, stretching
valve is opened, on the cavity of the oil through the expansion of
the valve into the inferior vena; and part of the oil on the
compensation, by an oil storage cylinder into the inferior vena.
The two throttle valve on the oil shock absorber damping effect to
Due to the expansion of the valve spring force is greater than the
flow valve, and stretching valve hole distribution area is smaller
than that of the flow valve, which makes stroke stretch of damper
of damping force is greater than the compression stroke damping
force, to quickly reduce the spring shell shock.
