伸缩性休克吸收器：

减震器的功能：

减震器是用作弹簧装置的悬架系统的一部分，可在柔韧性和刚度之间妥协。它通过提供阻尼并将其耗散成热量，吸收了转化为轴垂直运动的冲击能量。

减震器的目的：

(i) To control the vibrations on springs.
（ii）提供舒适的旅程。
（iii）行动灵活并足够僵化。
(iv) To resist the unnecessary motion of the spring.

Construction of Shock Absorber :

The upper eye of the telescopic shock absorber is attached to the axle and the lower eye is attached to the chassis frame as shown in Figure 4.55. A two-way valve V1 is connected to a rod. Another one two-way valve V2 is connected to the lower end of the cylinder. The fluid occupies in the space between above and below the valve VI and also the annular space between the cylinder and tube. A gland is provided on the head. Fluid scrapped out by the rod is brought down into the annular space through the inclined passage.

Working of Shock Absorber :

当车辆遇到坎坷的时候,莎莉e will move up. So, the fluid follows from the lower side of the valve V1 to the upper side. Due to less volume of the space above valve V1 than the volume of the rod, the pressure is exerted on valve V2 Thus, the damping force is produced by this pressure of the fluid. The fluid will flow from the upper side of the valve V1 to the lower side when the lower eye moves down and from the lower side of the valve V2 to its upper side.
When a car absorbs shocks from the road surface, the suspension springs will compress and expand because the spring has the characteristic of continuing to oscillate for a long time of oscillation to stop. So, a riding comfort will be poor even the damp oscillation is supplied. Shock absorbers provide better road-holding characteristics and improved steering stability to tires.

强力是阻尼力，人体的振荡越多。但是，阻尼效果产生的冲击比强度更强的阻尼力的强度更大。阻尼力随活塞的速度而变化。

减震器的类型：

1。Mechanical shock absorber (friction type)
2。Hydraulic shock absorber.

Again the hydraulic shock absorbers are further divided into various types.
1.货车类型
2。Piston type
a. Single-acting
b. Double acting
3。汤姆pic type.

Twin-Tube or Dual Tube Shock Absorber

它是一种类型的减震器，其中使用了2个名为主管和次级管或壳的空心管，它们以望远镜类型的方式合并在一起，即次要管或壳内部的主管。

• The primary tube contains the moving piston, compression valve along with other assembly components and is filled with high viscosity index oil.
• The secondary tube or shell contains the primary tube along with low-pressure gas (mostly nitrogen gas).
• This whole assembly of twin-tube is surrounded by a coil spring that provides the stiffness and also helps this assembly to regain its initial position after actuation.

单管减震器

它是一种类型的减震器，其中使用单管，将移动活塞放置在其中。

• High viscosity index oil along with the low-pressure gas (nitrogen in most cases) is filled inside a single tube in a particular proportion.
• The oil and gas-filled inside this single tube is separated by a floating piston that is placed airtight inside the tube.
• 整个组件被与双管减震器相同的线圈弹簧包围

Mono-shock悬架系统的优点

1.单震悬架系统改善了摩托车的处理坑洼或不良道路，因为所有力量都集中在某一时刻。
2。Due to position of mono-shock suspension is placed ahead of the rear axle at the center of摩托车，挥杆臂的运动没有直接转移到悬架上，这允许更稳定
3。motorcycle performance is more constant than using double shock.
4。More stylish suspension system.

Gas-filled mono-tube shocks

为了防止油中消除冲击性能的油中的泡沫和气泡，充满气管的气管冲击在油室上方有一个高压氮。这种高压气体使气泡很难在油中形成，即使减震器吸收器进出非常迅速地移出，就像在非常崎rough或垫板的道路上快速行驶时一样。

充满气体的冲击是昂贵的，因为它们需要严格的制造公差，但是它们对褪色非常有抵抗力，因此在越野赛车和集会中很受欢迎。顺便说一句，充满气体的冲击与“空气冲击”不同，后者使用与冲击油分开的空气室。空气弹簧实际上是一个空气弹簧，当通过阀添加或卸下空气时会升高或降低车辆。

充气减震器的优势

后端使用的充气减震器的优势

1。The full diameter of the tube can be used as a working chamber and thereby a大量的油可用于阻尼。
2。The larger volume of oil made available in any one stroke because of theadjustments between gas and oil volumes provides a better facility for the阻尼力。
3.充气减震器中热量的耐受性更大。
4。Gas-filled shock absorber gives longer life to tires and other related components在悬架中，例如弹簧，刷子等。
5.充满气体的减震器旨在减少油的泡沫。
6。Provide stability while graduating turns.

伸缩性减震器和充气减震器的差异。

Sr.No.	望远镜减震器	气填充减震器
1。	在此中，只使用液压油。	在这种情况下，使用石油和天然气。
2。	The tolerance to heat is less.	The tolerance to heat in gas-filled shock the absorber is greater.
3。	In this foaming of oil may occur.	充满气体的减震器旨在减少油的泡沫。
4。	大气条件不会影响系统。	The atmospheric condition affects on the system.
5。	The operating cost is lower.	与液压油相比，氮气的成本更多。
6。	Maintenance is comparatively easy.	Maintenance is difficult as compared to the hydraulic shock absorber.
7。	The damping effect is relatively less.	Better damping is obtained.

Advantages of telescopic shock absorber:

1。A large amount of energy is dissipated due to a large volume of fluid displaced without causing a high-temperature rise.
2.由于缺乏连接的手臂枢轴，阻尼器没有磨损的发育。
3。The applied force is increased when compared to the indirect-acting type. Low fluid pressure due to the fairly large piston area occurs with reduced levers.
4.由于压力较低和进入储层的旋转轴的缺失，泄漏的漏洞非常小。
5.费用小于弹簧。
6.对于大多数伸缩阻尼器，不需要补充。
