After uneven pavement, while shockabsorbing spring can filter road vibration, but the spring itself will have reciprocating motion, which is used to control this kind of shock absorber spring absorber is too soft, the body will be jumping up and down, shock absorbers too hard or too much resistance will impede the normal work of the spring. Suspension system on the conversion process, the hardware and hardware to the shock absorber of the spring with, and the spring hardness is closely related with the weight, so heavier vehicles generally use the shock absorber cited the crankshaft and connected devices, used to counter the crankshaft torsional vibration (that is, by crank the ignition cylinder and twist the impact of the phenomenon). 【 Classification】 Shock Absorber From the shock absorber damping materials have divided this point there are two types of hydraulic and pneumatic, as well as a variabledamping shock absorber. Now the shock absorbers are: 1. Rubber shock absorber。 。 3. air type shock absorber。 4. Oil air dampers。 5. the whole oil type shock absorbers. 【 The structure of shock absorber】 The structure of shock absorber piston rod with a tube inserted in the tubeinfull of oil. Orifice Pistons have made have been separated from the piston space of two parts oil to each viscous damping is through the oil produced Orifice, Orifice smaller, the greater the damping force, the greater the viscosity of oil, the greater the damping force. Orifice size if the same work faster when the shock absorber, the damping influence of the General Assembly had to absorb a result, the exit of Orifice to set up a diskshaped valve spring, when the pressure change when the top valve was opened, Orifice opening larger, smaller damping. As the piston is a twoway movement, so both sides are equipped with piston valve spring, respectively, called the pression valve and valve done. Shock absorber according to their structure can be divided into double and single tubetype. Binoculartype shock absorber means there are both inside and outside the two cylinders, pistons, including tubeinmovement, as a result of the entry and out 43 piston rod, the volume of oil inside the cylinder increases with the contraction, it should be exchanged with the outer tube to maintain balance within the cylinder oil. So have a double shock absorber in the fourvalve, that is, in addition to the abovementioned two throttle piston, there are both inside and outside the tube in a plete exchange between the valve and the flow pensation valve. Compared with the doubletype, single tubetype shock absorber simple structure, a reduction of a valve system. In the lower part of cylinder equipped with a floating piston, (the socalled floating piston rod means that there is no control over their movements), the following in the floating piston to form a sealed chamber, there are highpressure nitrogen charge. As a result of the abovementioned piston rod into and out of oil caused by a change in liquid height of floating through the floating piston to automatically addition to the abovementioned two types of shock absorber, there are adjustable shock absorber resistance. It can be changed through an external operation to the size of Orifice. Recently, the car will be electronically controlled shock absorber as a standardtype equipment, traveling through the sensor detection, and by a puter to calculate the best damping force, so that the damping force shock absorber to adjust automatically the work of institutions. The working principle of automobile shock absorbers: Suspension system ponents due to elastic vibration generated by the impact, in order to improve vehicle ride fort, suspension elastic element in parallel with the installation of shock absorber for the attenuation of vibration, automotive suspension systems are used in hydraulic shock absorber damping , and its working principle is that when the frame (or body) and the interaxle relative motion by vibration o
