A car shock absorber is a critical component of a vehicle's suspension system. Its primary purpose is to absorb and dampen the energy from road impacts, ensuring a smoother ride and better control. Without shock absorbers, a car would bounce excessively, making it difficult to steer, brake, or maintain stability. How it Works: Shock absorbers control the movement of the car’s springs by converting kinetic energy (from road bumps and vibrations) into thermal energy, which is dissipated. This is typically done using hydraulic fluid or gas. Key Components.unique auto spars.car shocker supplier. Piston Rod: A metal rod connected to the vehicle's suspension that moves in and out of the shock absorber's cylinder. Cylinder: Houses hydraulic fluid or gas that resists the piston’s movement.car shocker supplier.xf 2.2 Front car shocker. car Shocker Supplier. Valves and Orifices: Regulate fluid or gas flow to provide resistance and control the damping effect. Seal: Prevents leakage of hydraulic fluid or gas.
