Abstract

The invention relates to a non-clamping anti-pollution single-cylinder shock absorber assembly, which comprises a cylinder body and a free piston which is inserted into the cylinder body and can move in a reciprocating manner, wherein the free piston divides the interior of the cylinder body into a liquid cavity and an air chamber, one end of the free piston is connected with a piston rod and can be movably inserted into the cylinder body, and a sealing ring is arranged between the free piston and the inner wall of the cylinder body. The anti-pollution single cylinder bumper shock absorber subassembly of sticking that thereby provides the impurity of collecting prevention jamming to reduce friction torque makes damping force change slow down.

Description

Anti-pollution single cylinder bumper shock absorber subassembly of no jamming
Technical Field
The invention relates to a hydraulic shock absorber, in particular to a clamping stagnation-free anti-pollution single-cylinder shock absorber assembly.
Background
The single-cylinder type shock absorber is an important part of an automobile, and aims to reduce the vibration of a vehicle body and improve the comfort of the vehicle in the running process, the single-cylinder type hydraulic shock absorber is generally configured as follows: the cylinder comprises a single cylinder body, a free piston which is inserted into the cylinder body and can move back and forth, wherein the free piston divides the inner part of the cylinder body into a liquid cavity and an air cavity, the liquid cavity is divided into a stretching side cavity and a compressing side cavity, a piston rod is connected with one end of the free piston and can be movably inserted into the cylinder body, and a sealing ring is arranged between the free piston and the inner wall of the cylinder body in order to ensure the sealing performance between the air cavity and the liquid cavity of the cylinder body.
In the above-described single-tube hydraulic shock absorber, the seal ring is tightly fitted to the cylinder body, and the free piston moves relative to the cylinder body. The air chamber lubrication condition is relatively poor, fine pollution impurities are easily generated in the movement process of the free piston, the impurities are clamped between the maximum excircle of the free piston and a cylinder body, and large friction force is generated.
Disclosure of Invention
The invention aims to solve the technical problem of providing a clamping stagnation-free anti-pollution single-cylinder shock absorber assembly which can collect impurities so as to prevent clamping stagnation and reduce the friction torque so as to slow down the change of the damping force.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a there is not anti-pollution single cylinder bumper shock absorber subassembly of jamming, but includes the cylinder body and inserts cylinder body and reciprocating motion's free piston, and a sap cavity and an air chamber are cut apart into with the inside of cylinder body to free piston one end is connected with the piston rod to movably insert in the cylinder body, be provided with the sealing washer between the inner wall of free piston and cylinder body, its characterized in that, free piston is close to air chamber one end excircle and is equipped with a plurality of sets of annular, scribble in the annular and wipe viscous grease.
By adopting the technical scheme, even if impurities appear, the annular groove can be collected, the viscous grease can adsorb the impurities, the free piston and the cylinder body are not easy to block, the free piston runs stably, sudden change of damping force can be slowed down, and the comfort of vehicle running is ensured.
The anti-pollution single-cylinder shock absorber component without clamping stagnation can be further arranged as follows: the free piston is arranged by inclining 1-5 degrees from the excircle at one end close to the liquid cavity to the circle center of the excircle.
By adopting the technical scheme, when the free piston is in inclined contact with the cylinder body, the force-arm ratio is reduced, so that the friction torque is small, the free piston runs stably, sudden change of damping force can be reduced, and the aim of damping is fulfilled.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Drawings
FIG. 1 is a perspective view of the present invention;
Fig. 2 is a partially enlarged view of the present invention.
Detailed Description
the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the anti-pollution single cylinder bumper shock absorber subassembly of no jamming, including cylinder body 1 and insert cylinder body 1 in and but reciprocating motion's free piston 2, free piston 2 is with 1 inside division of cylinder body become a sap cavity 11 and an air chamber 12, and 2 one end of free piston are connected with the piston rod to movably insert in the cylinder body 1, be provided with sealing washer 3 between the inner wall of free piston 2 and cylinder body 1, free piston 2 is close to air chamber 12 one end excircle and is equipped with a set of annular 21, scribble viscous grease in the annular, free piston is close to 1 to 5 settings of slope of sap cavity one end excircle centre of a circle.
