Description

Technical Field

[0001] The utility model relates to the technical field of energy absorbing and shock absorbing rod maintenance, in particular to an energy absorbing and shock absorbing rod. Background Art

[0002] Energy-absorbing shock absorber rods are designed to reduce bumps, vibrations and impacts during vehicle driving by controlling the damping force of the shock absorber. The shock absorber can convert the dynamic energy generated by uneven road surface, braking and cornering into heat energy and dissipate it through the damping oil in the rod, thereby reducing the vibration amplitude of the vehicle and providing a smooth driving experience.

[0003] However, the common energy-absorbing shock absorber rod uses hydraulic oil for damping, which has a damping effect on the shock absorber through its viscosity and flow characteristics. The hydraulic oil is usually located inside the shock absorber rod of the vehicle suspension system, and the shock absorber rod is usually installed on the chassis of the vehicle. Therefore, the replacement of hydraulic oil requires lifting the vehicle or disassembling some suspension components to reach the position of the shock absorber rod, which is a relatively cumbersome process.
