Abstract

The invention discloses an external electromagnetic throttling valve type double-air-chamber adjustable damp shock absorber which solves the problem that only a finite number of throttling holes are formed in a valve core and the problem of installation position of a throttling valve. The shock absorber comprises a shell, a main piston and a piston rod, wherein the lower end of the piston rod fixes the main piston and is arranged in the shell; the main piston divides the inner part of the shell into a compressed oil chamber and an extended oil chamber; a hollow cavity is formed in the piston rod; the valve core is arranged in the hollow cavity; the valve core divides the hollow cavity into a first cavity and a second cavity; a front end hole for communicating the first cavity and the compressed oil chamber is formed in the piston rod; a compression stroke throttling hole for communicating the first cavity and the extended oil chamber is formed in the side wall of the piston rod; and an extension stroke throttling hole for communicating the second cavity and the extended oil chamber is formed in the side wall of the piston rod. The shock absorber realizes minimized design for the throttling valve; furthermore, due to the throttling hole, the shock absorber has a better shock absorption effect and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of shock absorbers in vehicle suspension systems, in particular to an external electromagnetic throttle valve type double air chamber adjustable damping shock absorber. Background technique [0002] The shock absorber is one of the key components in the vehicle suspension system, and its performance directly affects the ride comfort and handling stability of the vehicle. From the perspective of damping materials, shock absorbers are mainly divided into hydraulic type and pneumatic type. Since oil has a better damping effect than gas, hydraulic shock absorbers are mostly used at present. The internal structure of the hydraulic shock absorber can generally be simplified as figure 1 The basic structure shown, figure 1 Among them, 1 is the piston rod, 2 is the main piston, 3 is the throttle valve, 4 is the oil chamber, 5 is the upper chamber, and 6 is the lower chamber. When the piston rod 1 is stretched, the ...
