Embodiment Construction

[0021] The following is a detailed description of the assembly method of the military barrel shock absorber in conjunction with the attached drawings:

[0022] figure 2 A drawing of the shock absorber piston assembly is shown. According to the sequence of compression valve plate, upper valve plate, piston, piston ring, piston spring seat, piston spring, lower valve plate, recovery valve plate, adjusting gasket and piston tightening nut, assemble the piston assembly on the piston rod welding part On the assembly, the piston rod is then riveted.

[0023] image 3 As shown in the bottom valve assembly diagram, install the bottom valve screw, compensation valve spring, compensation valve plate, bottom valve seat, safety valve spring seat, safety valve spring, and bottom valve tightening nut in sequence, tighten the nut, and then tighten the bottom valve. When the valve is screw riveted, the assembly of the bottom valve assembly is completed.

[0024] Weld the piston rod, dust...

Abstract

The invention relates to a combined type piston of a telescopic shock absorber, comprising a piston rod assembly, a piston assembly and a bottom valve assembly, wherein the bottom valve assembly of the shock absorber is pressed on a piston cylinder, and a compensating valve spring, a compensating valve plate, a bottom valve seat, a safety valve spring seat, a safety valve spring and a bottom valve tightening nut are sheathed on a bottom valve bolt. The bottom valve tightening nut is connected with a screw by a screw thread, and the compensating valve spring, the compensating valve plate, the bottom valve seat, the safety valve seat and the safety valve spring are compressed; simultaneously, oil passing holes facilitating the piston to take the choking effect under the low-speed condition are processed on in the circumferential direction, and oil through holes used for quickly unloading under the piston high-speed condition are processed on the bottom valve seat in the central position. The invention has the beneficial effects that the body vibration, in particular the pitching vibration can be effectively attenuated and the safety, the smoothness as well as the cross-country speed are increased.

Description

technical field [0001] The invention belongs to the application field of hydraulic machinery and motor vehicles, and relates to a piston of a barrel type shock absorber. Background technique [0002] Suspension is the general term for all force transmission connection devices between the vehicle body and the axle (or wheel). In a popular sense, the suspension system is composed of elastic elements, damping elements, guiding devices and their control systems. Of course, in terms of specific structural realization, the above-mentioned components may not all appear in an independent form. [0003] In the prior art, except the cylinder type shock absorber, the types of damping elements used in the vehicle suspension system mainly include: friction type shock absorber, lever-piston type hydraulic shock absorber, vane type shock absorber and the like. The structure of the friction shock absorber is relatively simple, but due to the wear of the friction surface during use, the pe...
