A Used VW Crafter 2.5 Tdi For Sale Drive Need To Know About Absorber Types
A VW crafter 2.5 TDI for sale need to know, Telescopic absorber is the most common type and it is interesting to consider the various construction features that have made it more efficient and reliable. First of all, to obtain a good compromise between comfort and stability, it is necessary that the damping effect (hydraulic brake) in extension is much more energetic than that in the compression phase.
Slower Stroke
In practice, a ratio of 3 to 1 is normally adopted but, for high-performance vehicles or in certain applications intended for competitions, it can also be reached at the additional point. It follows that the specific one-way valves for the passage of the hydraulic fluid in compression and extension, they will have very different calibrations. In fact, if a driver or used car buyer pushes the bodywork of a car down near a wheel with energy, a person will notice a relatively soft and fast lowering during compression and a very slow and additional contrasting return stroke (extension). A buyer is ready to pay VW crafter 2.5 TDI price need to note this simple test allows us to verify, with good approximation, the efficiency of the shock absorber in low vehicle speed conditions. But when at the same speed, very violent accelerations are transmitted to the elastic elements and shock absorbers.
Pressure and Accelerations
a buyer needs to think of the collisions between the tire and strong road irregularities such as potholes, bumps or other. In these conditions, the high-speed valves intervene, the efficiency of which can be checked by special shock absorber test benches. Another type of absorber is known as Oleopneumatics, in that perspective, used car drivers need to aware, the hydraulic telescopic shock absorbers contain, in addition to oil, as well as a certain amount of air. The friction encountered by the fluid in the forced passage through the valves creates heat and a strong pressure difference between the two faces of the piston when it is subjected to violent accelerations. In extreme conditions, harmful phenomena of cavitation and the formation of bubbles of air and foam can occur, such as to drastically reduce the damping action.
Electrically Connected
The experts and technicians experimented and patented a system designed to overcome this phenomenon, physically separating the oil from the air or gas and increasing the internal pressure on the oil by means of compressed gas (nitrogen or compressed air) in a separate room. Advanced high-performance road cars are often equipped with electronically controlled active suspension. The systems can be fully automatic or with different modes i.e. standard, comfort, sport which can be selected by special command from the driver according to the various conditions of use of the vehicle. The basic scheme includes an electronic control module that receives information from the movement sensors (vertical and horizontal accelerometers) and adaptive shock absorbers electrically connected to the module from which they receive the calibration inputs.
