Inflation method and device for inflatable automobile shock absorber

Abstract

A kind of method of charging for gas-filled type auto car's dampener. First, fill the outer shell with the inner shell,the valve base and the valve,the headed piston and the piston rod,the guide, then install it on the clamp device vertically,and put a height adjustment platform at the bottom of the outer shell;fill the agent oil into the outer shell; make the charging cylinder axially move at the clamp device, then make the lower port of the charging cylinder oppositely joint with the upper port of the outer shell,and jog the outer shell and the charging cylinder tightly through the height adjustment platform,install a joint ring at the joint of the charging cylinder and the outer shell; put the oil seal on the upper port of the charging cylinder, thrust the oil seal into the charging cylinder through the propelling plant; fill the fixity gas into the outer shell through the charging connector of the charging cylinder, the volume ratio of the agent oil and the gas is 2:8-4:6; after charging, thrust the oil seal in the apposite position through the propelling plant; Make the oil seal tightly and disassemble the outer shell form the clamp device. The advantage is easily handled, high operating efficiency, good charging fruit and sealing performance,and the charging device structure is simple, low cost.

Description

technical field [0001] The invention relates to an inflating method and an inflating device for an inflatable automobile shock absorber. Background technique [0002] When the existing automobile shock absorber is assembled, the piston rod is pushed to the bottom of the cylinder body, and then medium oil is filled into the cylinder body of the shock absorber, and vibration reduction is realized through the damping effect of the medium oil during operation. The shock absorber made by this method has the following problems: when the shock absorber is filled with medium oil, the piston rod is at the bottom of the shock absorber cylinder, and when the piston rod moves up during driving, the cylinder at the lower part of the piston A vacuum zone will be formed in the body, and the vibration reduction effect will not be achieved when the piston rod moves down. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existi...
