Description
How do shock absorber work?
Explanation of the working principle of the double-acting cartridge damper. During the compression stroke, piston 3 in the damper moves downwards as the wheels of the vehicle move closer to the vehicle body, and the damper is compressed.
The volume of the lower chamber of the piston decreases, the oil pressure rises, and the oil flows through the flow valve 8 into the chamber above the piston (upper chamber). The oil is then pushed through the compression valve 6 and flows back into the oil reservoir 5. The oil-saving effect of these valves creates a damping force for the compression of the suspension.
The dampers are stretched during the extension stroke, with the wheels moving away from the body equivalent. At this point, the piston of the damper moves upwards. The oil pressure in the upper chamber of the piston rises, the flow valve 8 closes, and the oil in the upper chamber pushes open the tension valve 4 and flows into the lower chamber.
Due to the presence of the piston rod, the oil flowing from the upper chamber is not sufficient to fill the increased volume of the lower chamber, and a vacuum is created in the lower chamber, which is replenished by the oil in the reservoir by pushing open the compensation valve 7. Due to the throttling action of these valves, the suspension is damped during the extension movement.
As the stiffness and preload of the extension valve spring are designed to be greater than that of the compression valve, the sum of the channel load areas of the extension valve and the corresponding constant gap is smaller than the sum of the cross-sectional areas of the compression valve and the corresponding constant gap under the same pressure. This results in the damping force generated by the extension stroke of the damper being greater than the damping force of the compression stroke, thus fulfilling the requirement for rapid damping.

Coil spring Shock absorber Impact.
When the vehicle is subjected to vibrations and shocks from uneven surfaces, if these are transmitted directly from the wheels to the body, the ride and handling stability are poor, and the shock absorbers maintain the stability and comfort of the body, making the vehicle easy to maneuver. The stability and handling of the vehicle have a direct impact on the safety of the driver.
You will find that shock absorbers should be considered in three aspects: appearance, quality, and function.
Appearance of Coil spring Shock absorber
As the saying goes, a man depends on his clothes; a Buddha depends on his gold. If a product attracts the customer’s attention at first glance and enables him to voluntarily gain an in-depth understanding of the product, then it must be non-appealing. Nowadays, consumers are looking for fashionable, beautiful, and personalized products, and it would be best if they could be customized. Traditionally cast, oxidation is now an innovation that affects the appearance of the product.
Quality of Coil spring Shock absorber
Quality assurance is the foundation, and if a shock absorber first attracts customers by its appearance in terms of materials or workmanship, it gives them peace of mind. The next step is to use the data to demonstrate the service life of the dampers in terms of the number of vibration damping endurance tests.
Functionality of Coil spring Shock absorber
A very important point: innovation is indispensable to distance yourself from other products, especially when it comes to functionality. For example, the adjustable function, which can be adjusted to road and body conditions, is more practical and more user-friendly.
