The piston stroke of the crank arm shock absorber is much shorter than that of the cylindrical hydraulic shock absorber. Therefore, the steam pressure of the crank arm shock absorber can reach 75-30mpa, while that of the cylindrical shock absorber is only 2.5-5cpa. The quality of the cylinder shock absorber is only about 1 / 2 of that of the lower swing arm type. Moreover, the production manufacturing are convenient the service life is long. The three most common structural forms of cylindrical shock absorber include: double tube type, single cylinder inflatable type double barrel inflatable type.

The principle of double cylinder hydraulic transmission shock absorber is shown in figure 16-4. In which a is the working cavity C is the compensation chamber. The middle of the two chambers is connected according to the valve system. When the car wheels run up down, the piston rod 1 is pushed to move left right in the working cavity a to drive the shock absorber to flow through the damping hole on the relative oil circuit board, which changes the mechanical energy into energy consumption. When the wheel vibrates upward, that is, when the suspension system shrinks, the piston rod 1 moves downward to keep fit. The hydraulic oil enters the upper cavity of the working cavity according to valve I II seals the plane bearing. However, since the hydraulic cylinder 9 occupies a part of the volume, a part of the hydraulic oil must flow through the valve IV into the compensation chamber C. when the wheel vibrates downward, i.e. the suspension system is extended, the piston rod 1 moves upward to keep fit, the working cavity a When the working pressure of the hydraulic cylinder rises, the hydraulic oil is injected into the lower chamber through valve I, showing the vast majority of the spreading damping coefficient. Also, a part of the hydraulic oil passes through the clearance between the hydraulic cylinder the guiding seat enters the compensation chamber the return hole 6. Similarly, due to the volume occupied by the hydraulic cylinder, when the piston rod moves upward, a part of the hydraulic oil of the plane bearing steering must be injected into the working cavity through the valve III Inferior chamber. The heat generated in the whole process of shock absorber operation is released by hydraulic cylinder 3. The operating temperature of the shock absorber can reach 120 ℃, sometimes even 200 ℃. In order to show the indoor space the hydraulic oil will swell after the temperature rises, the hydraulic oil of the shock absorber can be filled too much. However, in the compensation chamber, the height width ratio of the hydraulic oil should be half of the length of the cylinder liner, so as to prevent the gas entering the compensation chamber through the framework seal 7 even into the working cavity through the valve III at the extreme extension position, resulting in the emulsion of the hydraulic oil Liquid, endangering the working characteristics of shock absorber.
