Automotive rear shock absorber assembly function
The main function of the rear shock absorber is to buffer and absorb shock, delay the expansion and compression speed of the spring, absorb shock force, and ensure that the spring can continue to work stably after recovering deformation .
When the vehicle is driving on an uneven road surface, although the shock absorber spring can filter out most of the vibration, the spring itself will still produce a certain amount of shock. At this time, the shock absorber plays a crucial role, it can effectively inhibit the reciprocating movement of the spring, so as to ensure that the vehicle can maintain a stable during the driving process, for the driver and passengers to bring a comfortable ride experience .
How shock absorbers work
Shock absorbers absorb and consume shock energy through a liquid or gaseous medium. When the vehicle is impacted, the medium in the shock absorber will be compressed, resulting in damping force, slowing down the rebound speed of the spring, to achieve the effect of shock absorption .
Construction of shock absorber
Shock absorber usually consists of the following parts: shock absorber body, dust jacket, spring, upper and lower spring pad, spring seat, bearing, top rubber and nut, etc. .
These components work together to ensure the proper operation and durability of the shock absorber.
Maintenance and replacement suggestions
Check for oil leakage : Observe the shock absorber for oil leakage. A healthy exterior surface of the shock absorber should be dry and clean. If oil is found leaking, especially hydraulic oil leaking from the upper part of the piston rod, it usually means that the shock absorber is damaged .
Test number of bounces : press the front or back hard and then release quickly, observe the number of bounces of the vehicle. If there are too many bounces, there may be a problem with the shock absorber .
emergency brake test : slow braking during driving, if the braking distance is significantly increased and the vehicle is shaking violently, there may be a problem with the shock absorber .
abnormal sound check : pay attention to whether there is abnormal sound during driving, especially when driving on the road with poor road conditions .
Through regular inspection and maintenance, the service life of the shock absorber can be extended to ensure the smoothness and safety of the vehicle.
The components of an automobile rear shock absorber mainly include the following parts: shock absorber, lower spring pad, dust jacket, spring, shock absorber, upper spring pad, spring seat, bearing, top rubber and nut .
Detailed composition of shock absorber assembly
shock absorber : the main function is to inhibit the shock of spring rebound after shock absorption and the impact from the road surface. Usually, hydraulic shock absorber is used to absorb and consume vibration energy by moving the piston up and down.
lower spring pad : located at the bottom of the shock absorber, reduce metal friction and abnormal sound, improve comfort .
dust jacket : prevent dust and sand into the shock absorber, protect the internal parts of the shock absorber, avoid damage .
spring : support body weight, absorb road impact .
Shock pad : located between the shock absorber and the spring to further reduce vibration and noise .
upper spring pad : located at the top of the shock absorber to reduce metal friction and abnormal sound .
spring seat : support the spring to ensure its stable work .
bearing : located inside the shock absorber, allowing the shock absorber to rotate smoothly .
top glue : located at the top of the shock absorber, play the role of buffer and sound insulation, reduce body vibration and noise .
nut : used to fix shock absorber assembly .
The role and importance of each component
shock absorber : the core component, absorbs and consumes vibration energy through the principle of hydraulic vibration reduction to ensure the smooth running of the vehicle.
spring pad : reduce metal friction and abnormal noise, improve ride comfort.
dust jacket : protects the internal parts of the shock absorber, prevents dust and sand from entering, and prolongs the life of the shock absorber.
spring : support the weight of the body, absorb the impact of the road to ensure the stability of the vehicle.
bearing : to ensure the smooth rotation of the shock absorber in the steering, to avoid holding and abnormal sound.
top glue : buffer and sound insulation, reduce body vibration and noise, improve driving comfort.
These components work together to ensure that the car provides good shock absorption and driving experience in all road conditions.
