减震器知识
Shock absorber knowledge
One, the principle of hydraulic shock absorber
When the frame and the axle to do
reciprocating relative application, piston
reciprocating in the damping cylinder moves
within the oil shock absorber shell is repeated
from the cavity through the narrow pore flow
into another cavity. They formed on the
vibration damping force of friction at the
liquid and wall friction and liquid molecules
within the.

Method two, check the shock absorber
1 make the car in poor condition of roads
roads ten km after parking, touch the damper
housing by hand, if not hot, indicating no
shock absorber internal resistance, shock
absorber does not work. At this time, can join
the proper lubricating oil, then test, if the
housing heating, for shock absorber internal
lack of oil, should add enough oil, otherwise,
the damper failure.

2 press the bumper, then release, if the car has
two to three jumps, then good shock absorbers.

3 when the car slowly driving and emergency
braking, if car vibration is severe, explain
shock absorber has a problem.

Advantages and disadvantages of the three,
shock absorber, hardness of soft

1 soft: comfortable riding, bump less stable.
But the intense driving, drag racing will be
very uncomfortable. Such as the Japanese car.

2 hard: take a slightly uncomfortable, but the
control of the strong. Such as the German car
line. In general, fish and bear's paw can not
have both, choose moderate hardness of the
best.
一、 液压减震器原理
当车架与车桥做往复相对运用时,活塞
在减震的缸筒内往复移动,减震器壳体内的
油液便反复的从内腔通过一些窄小的孔隙
流入另一内腔。此时液体与内壁的摩擦及液
体分子的内摩擦便形成对振动的阻尼力。
二、检查减震器的方法
1.使汽车在道路条件较差的路面上行驶
十公里后停车,用手触摸减震器外壳,如果
不够热,说明减震器内部无阻力,减震器不
工作。此时,可加入适当的润滑油,再进行
试验,若外壳发热,则为减震器内部缺油,
应加足油,否则,说明减震器失效。
2.用力按下保险杠,然后松开,如果汽
车有二到三次跳跃,则说明减震器良好。
3.当汽车缓慢行驶而紧急制动时,若汽
车振动比较剧烈,说明减震器有问题。
三、减震器软、硬度的优缺点
1.偏软:乘坐舒服,颠簸少,平稳。但
激烈驾驶、飙车会很不爽。如日系车。
2.偏硬:乘坐稍有不舒服,但操控性较
强。如德系车。 总的来说,鱼和熊掌不可
兼得,选择软硬适中的最好。
