Do You Know About Shock Absorber? When You Buy Used Nissan Qashqai Acenta 2016 For Sale

In dampers of hydraulic shock absorbers of Nissan Qashqai acenta 2016 for sale, the damping effect during springing is obtained from the resistance offered by the natural viscosity of the oil that is pressed by a sliding piston (connected by a rod to the suspension) within a sealed tube (fixed to the vehicle frame ) and drawn through small calibrated holes from one chamber to the other of the pipe. 

Efficient And Reliable

The forced passage of the oil through these chokes transforms the kinetic energy due to the movement of the piston into heat which will be absorbed by the oil itself and transmitted to the body of the shock absorber. By changing the dimensions of the calibrated passages, it is possible to vary the amount of the hydraulic brake, obtaining different damping values in compression and extension. Indeed, it is easy to understand that a small diameter hole offers greater resistance to the passage of the oil than a larger one and, consequently, in the first case, a greater hydraulic brake will be obtained. Moreover, even the adoption of more or less viscous oil makes it possible to vary the hydraulic brake. While the telescopic ones constitute the widespread type and it is interesting to take into consideration the various constructional features that have made it increasingly efficient and reliable. 

Additional Accelerations

First of all, to obtain a good compromise between comfort and stability, the damping effect (hydraulic brake) in extension should be very energetic than that in the compression phase. It follows that the special unidirectional valves for the passage of hydraulic fluid in compression and extension, they will have very different settings. In fact, if we push down the body of a car with energy down near a wheel, we will notice a relatively soft and fast lowering in the compression phase and a slower and very contrasted return stroke. In these conditions, the valves for high speeds intervene or the simple test allows us to verify, with a good approximation, the efficiency of the shock absorber in low vehicle speed condition. But when the speed is the same, additional violent accelerations are transmitted to the elastic elements and the shock absorbers. 

Reduced Action

Here is a need to think of the impacts between the tire and strong road irregularities such as holes, bumps or other. Besides, the telescopic hydraulic shock absorbers contain, in addition to the oil, also a certain amount of air. The friction encountered by the fluid in the forced passage through the valves creates heat and a strong difference in pressure between the two faces of the piston when it is subjected to violent acceleration. In extreme conditions, there can be harmful cavitation phenomena and the formation of air bubbles and foam, such as to drastically reduce the damping action. The auto experts experimented and patented a system designed to remedy this phenomenon, physically separating the oil from the air or gas and increasing the internal pressure on the oil by compressed gas (nitrogen or compressed air) in a separate way.
