This series of hydraulic vibration damper is specially designed for truck cabs to isolate road vibration effectively through mechanical energy conversion, which is suitable for heavy-duty transportation, construction vehicles and other harsh working conditions. No external power supply is required, and the structure is sturdy, providing drivers with durable and stable comfort protection.
Core Advantages
✅ High-efficiency vibration damping
The damping force is linearly optimized, which can attenuate more than 70% of low-frequency bumps (5-15Hz) and 50% high-frequency vibrations (20-30Hz), and reduce the vertical acceleration of the cab by up to 40% in real measurement.
✅ Quality Assurance
Precision forged piston rod and seal design,, passed 2 million times fatigue test, no leakage.
High temperature resistant hydraulic oil (-10℃~120℃) adapts to high heat environment. Outstanding high temperature resistance can be used for a long time at higher temperatures, generally its long-term use temperature can reach 150℃-200℃, which can meet the needs of sealing and vibration damping in high temperature environments. Good thermal stability: under high temperature, its molecular structure is stable, not easy to occur thermal decomposition, oxidation and other reactions, can maintain good elasticity, strength and abrasion resistance and other properties, even after a long period of high temperature, the decline in its physical and mechanical properties is also small.
✅ Maintenance-free design
One-piece closed structure, dust-proof and corrosion-proof, no need for regular oil filling, reducing the cost of use.
Working Principle
Compression Stage: When the cab is pressed down, the hydraulic oil generates reverse resistance through the precision valve to absorb the impact energy.
Rebound phase: spring assisted reset, valve throttling to control the rebound speed to avoid cab shaking.
Heat dissipation: the vibration energy is converted into thermal energy of the oil, which is naturally dissipated through the shell.
