What is the core of a car shock absorber
The shock absorber core of a car is a key component in the suspension system, made of carbon spring steel and mainly used to suppress spring vibration and road impact.
Function and Structure
The shock absorber core converts the vibration energy of the spring into heat energy through a hydraulic system or an inflatable structure, reducing the up and down bouncing and roll of the vehicle body and enhancing ride smoothness. Its working principle is divided into two stages: the compression stroke (with small damping) and the extension stroke (with large damping). Effective vibration reduction is achieved through the damping forces of different stages.
Material characteristics
Carbon spring steel features high strength and fatigue resistance, capable of withstanding repeated force deformation. It is a commonly used material for traditional shock absorber cores. Some modern vehicle models adopt shock absorber cores with variable damping technology, and their materials may contain special alloys or composite materials to adapt to more complex working conditions.
The core function of the automotive shock absorber core (also known as the shock absorber core) is to convert the impact energy received by the wheels into heat energy and absorb it, thereby suppressing the vibration of the vehicle body and enhancing the smoothness and safety of driving.
Specific functions
Youdaoplaceholder0 attenuates vibration
By converting mechanical energy into thermal energy through hydraulic damping or gas compression, more than 80% of aftershocks can be reduced. For example, in the compression stroke, a small resistance is used to buffer the impact, and in the extension stroke, a large resistance is used to suppress the rebound.
Youdaoplaceholder0 enhance tire grip
It quickly absorbs the impact of the road surface and adjusts the damping force (bidirectional adjustable design), enabling the tires to re-press the road surface within 0.1 seconds, reducing the loss of grip caused by bouncing, shortening the braking distance and enhancing the stability in corners.
Youdaoplaceholder0 protect the mechanical structure
Reduce the impact force by 70% to 85%, decrease the deformation of suspension components (such as the deformation of bushings by 40%), and extend the service life of the suspension system by approximately 30,000 to 50,000 kilometers.
Youdaoplaceholder0 adjust driving and riding comfort
The latest product can achieve multi-stage damping regulation through solenoid valve and mechanical valve technology, taking into account the flexibility of urban roads and the reinforcement of roll support at high speeds. It can respond to real-time road conditions 500 times per second.
The main manifestations of shock absorber core failure are hydraulic oil leakage, decreased or failed damping force. Common symptoms include abnormal jolting of the vehicle body, abnormal noise, and brake deviation, etc.
Cause of malfunction
Youdaoplaceholder0 hardware aging
The aging of the oil seal causes oil leakage, and the loss of hydraulic oil affects the shock absorption effect.
Deformation of the piston rod or scratches on the cylinder barrel leads to abnormal resistance.
Youdaoplaceholder0 uses environmental influences
Long-term driving on rough roads or overloading accelerates the wear of components.
Frequent sudden braking or acceleration causes the oil temperature to rise, shortening the service life.
Handling suggestions
Youdaoplaceholder0 Replacement principle
Youdaoplaceholder0 Single-side damage : If single-side damage is caused by accidental impact (such as curb collision), the faulty side can be replaced separately.
Replace on both sides of simultaneously: If performance deteriorates due to aging or long-term use, it is recommended to replace the coaxial (front/rear) at the same time to avoid differences in driving feel.
Youdaoplaceholder0 Maintenance points
Check the condition of accessories such as dust covers and buffer blocks, and replace damaged parts in time.
Replace the hydraulic oil regularly (it is recommended to do so every 80,000 kilometers or as per the manufacturer's recommendation) to prevent the oil from deteriorating.
If a fault in the shock absorber core is found, it is recommended to have it repaired in a timely manner to avoid further affecting the performance of the suspension system and driving safety.
