What does the shock absorber assembly consist of?
The shock absorber assembly is a complex system consisting of multiple components, including the shock absorber, lower spring pad, dust jacket, spring, shock pad, upper spring pad, spring seat, bearing, top glue and nut. This assembly system can be divided into front left, front right, back left, back right four parts, each part of the shock absorber at the bottom of the lug (connected to the brake disc) position is different, therefore, in the selection of shock absorber assembly, must clearly know which part of the assembly.
For the replacement of shock absorbers, the replacement of independent shock absorbers requires professional equipment and technicians, which is complex and dangerous. In contrast, replacing the shock absorber assembly is much simpler and can be done easily by simply turning a few screws.
In terms of price, the individual parts of the shock absorber kit are more expensive to replace. Because the shock absorber assembly contains all the components of the shock absorber system, the price is more economical than replacing each component separately.
In addition, there are differences in function between shock absorbers and shock absorber assemblies. The separate shock absorber mainly plays a shock absorption role, and the shock absorber assembly also plays an important role in the suspension system.
Why are the shock absorber and spring of the car's front suspension set together? The rear suspension is separate?
Some time ago, we said the advantages and disadvantages of various suspension of the car, the owner friends also like very much, and then the careful car friends found that some of the suspension of the suspension of the shock cylinder and the spring is set together, some are separated, this is why? Which is better? Today we'll talk about it.
What are the advantages of separating cylinder springs?
Some shock absorbers and springs are used in a one-piece design, that is, the spring is placed on the outside of the shock absorber, and there are separate types. What are the benefits of either? The advantage of the one-piece is that it can save space, and the shock absorber and the spring are in the same direction of movement, which can increase the support rigidity; However, the disadvantage is that it cannot be adjusted separately according to the body. The separate type can adjust the shock absorber separately, adjust it independently according to the positioning of different models and the law of vehicle movement, and control the attitude of the body more accurately.
Why is the rear suspension often separated?
This is inseparable from the above two suspension characteristics, the general car front is heavier, the support and space requirements are higher; The rear of the body is relatively large, and the rear side roll is relatively large when turning, and the rear attitude control of the body directly determines the comfort of the car, which is why it is easy to get motion sickness in the back row, so the rear suspension needs to be adjusted more carefully.
How to judge whether the shock absorber is faulty The shock absorber is an indispensable configuration of our vehicles, and its function is mainly used to inhibit the reciprocating movement and the impact from the road when the spring rebounds after absorbing the shock. When passing through the uneven road surface, although the shock absorber spring can filter the road vibration, the spring itself will shock, and the shock absorber acts to inhibit the reciprocating movement of the spring. An important part of the vehicle, if the shock absorber is dropped, it will not have a little impact on the body support, but without the shock absorber it will not be able to escape the spring rebound, the most obvious feeling is that the stability of the vehicle is poor, and after the speed bump or pothole road surface, the vehicle will have a significant shake, and when it passes through the unpaved road surface, it will have serious bounce. When turning the corner, it will also cause a lack of tire grip due to spring vibration, so there will be a certain danger when we drive, so it is necessary to check our shock absorber during maintenance. So how to judge the shock absorber?
1, hard to press the front or back, and then the horse release, if the vehicle has only 1-2 bounces, it indicates that the shock absorber works well;
2, the car slowly and then emergency braking, if the steam is more intense, indicating that there is a problem with the shock absorber;
3. If the vehicle bounces 3-4 times when passing the speed bump, there is a problem with the shock absorber;
4. Observe whether there is oil leakage outside the shock absorber;
5, driving on good road conditions, hear the shock absorber has a different sound, there may be a problem. Do shock absorbers have to be replaced in pairs? To separate the situation, if there is a root oil leak or abnormal sound, and we usually drive the road condition is good, the number of car kilometers is not too, this situation only needs to replace the root, there is no need to replace two roots. If the road conditions are not too much every day, often run some non-paved roads, the number of car kilometers is also compared, this situation is the most left and right roots at the same time to replace. Because the damage of the shock absorber has a lot to do with our usual road conditions, if you often walk unpaved roads, the performance attenuation of the shock absorber will be compared. The hardness difference between the two sides of the root is large, and the side is hard and soft, which will affect the stability of the vehicle. The life of the shock absorber is generally compared, and the normal situation is no problem with 5-6 years or 8-100,000 kilometers. In addition, if you replace the shock absorber, you need to do four-wheel positioning.
