Modified car dictionaries: damping adjustable suspension
When the car modification, suspension aftermarket auto parts mentioned, we often hear "adjustable damping" word, then what is "damping" mean? When we are at a fixed rate of compression or stretching the shock resistance it produces is called damping.
Damping shock absorbers adjust by changing the internal valve section to achieve damping value changes. These shock tube core activity has an adjustable valve, when we swirling external shock in the shock absorber adjustment knob will move the linkage a movement within the valve to change the damping piston oil when passing through sectional diameter alive valve. When the valve area is reduced, the damping oil flow difficulties, shock absorbers naturally stretching and compression becomes difficult, then what we call the shock absorbers become tough up, and vice versa transfer large valve area, the shock will become soft .
In Japan Automobile specifications (JASO C602) in order to make the provisions of resistance movement speed 0.3m / s time to represent the performance of the shock, we called the damping unit of Kgf, called stiffer shock absorbers is actuated When can produce relatively large resistance. When we let the shock absorbers at a very slow speed compression or stretching, its only friction resistance, damping oil from the internal organization of almost no resistance. However, aftermarket engine parts when used as moving speed increases, the resistance will increase and the shock actuation speed change rate proportional to the square, which means that the actuator speed increased to 2 times the resistance but will increase four-fold.
Shock resistance can be divided into two parts, compression and rebound, compression resistance and hardness of spring bonus, increase the intensity of spring actuation, while rebound resistance is occurred after shock compression spring by road rebound stroke, the biggest reason for this is the existence of shock absorbers, which is used to resist compression of the spring and then the tire pressure back to the ground forces, slowing the rebound of impact and keep the vehicle stable. General road use of shock absorbers, shock-absorbing stroke resistance is typically much smaller than the rebound stroke, as it will affect the comfort of road shock-absorbing stroke when the resistance is too great, when the impact of road vehicles for the rebound damping force and when the ratio is about 1: 3, but with the car it was 1: 2 to 1: 1.5, the higher the ratio will reduce comfort, but it can improve the tracking of the road passing through irregular.
Shock absorber damping adjustment, the most obvious effect is that the dynamic response of the vehicle when passing through uneven road changes. However, for high-end users, adjustable damping will affect the grounding of the shock absorber is moved up and down and the tire grip, while different damping values for the car shock absorber by compressing / stretching at the corner, engine parts uk express the dynamic will be very different. For example, more hard damping, dynamic relatively stable, but the reaction will be slower when continuous curve, soft damping then let the body more sensitive, dynamic cornering relatively lively.
Positive vertical shock damping adjust its upper portion located shock, and its inverted shock damping adjustment means in the lower portion.
