1 . The most important function of the suspension system ls to supply comfortable , safe nde cot- trol

2. According to the article , we know that there are five basic types of spnngs used ln sus,eT"- sions ： coil spring , leaf spring , torsion bar spring , traction,barand air spnngn

3. The disadvantage of a coil spring ls its compactness , lack of moving parts , and excellentweight supporting characteristics.

4. According to e passage , leaf springs are often used on the front suspension of front drive vehtcles

5. When the coil springs , leaf springs , torsion bar spring ,L air springs ls defected , thls couldd cause the car to bounce up and down without any control

6. Shock absorber movement ls limited by forcing fluid , d which causes the shock absorber to causes the shock absorber

 compress or extend at a slow rate.

EXERCISE 3     

1. The leaf springs or leaves. most commonly used tn automobiles is' made up of several long plates ,

2. Suspension refers to the use of the front and rear springs to suspend a vehicle ' s rear springs to suspend a vehicle sprung weight

3. Shock absorber are hydraulic restricting devices used to hmt the speed of spring action.

4. The car frame is connected to the axles by springs which absorb road shock

5. The coil springs is made from a length of steel rod wound Into a coil.

6. The front-suspension system must allow the wheels to move up and down.

7. In operations, the lower control arms pivot up and down , twisting the torsion bars spring.

8. Rebound clips are place along the spnng to prevent separahon of the leaves when the spring rebounds.

 EXERCISE 4  

1.coil spring : a round bar of spring steel wound into the shape of a coil   

2.leaf spring : several layers of spring steel stacked one upon the other     

3.torsion bar : spring a long solid steel shaft held at one end to the suspension s control arm

4.air spring : a rubber bag or bladder full of air

5.shock absorber : a hydraulic device by forcing fluid through passages or orifices

6 suspension : use of the front and rear spring to suspend a vehicle  

 EXERCISE 5     

1. We all Know that springs are the major component（弹簧是主要部件) .n automobile suspension.

2. The automobile suspension is one of the major automobile system (汽车的主要系统之一。) . Could you please tell me something？ .

3. One of the advantages is that the use of suspension system has increased strength and durability of components (悬架的运用提高了零部件的强度和寿命).

4. To the lower body plate , suspension system is attached which transmits the weight of the body and other components to the axles and wheels（从而将车身和其他部件的重量传递到车桥和车轮上) ·j

5. Shock absorbers operate by having a piston force fluid through a small opening ( 活塞使液体强制通过一个小限制孔)
