Abstract

A structure of an automobile shock absorber, the shock absorber includes a shock absorbing cylinder and an air bag unit, the air bag unit has a bag body, a top cover and a base assembled on the upper and lower ends of the bag body, the The top cover of the airbag unit is fixed on the ring convex part of the upper end of the bag body with the peripheral snap ring part, the base is assembled on the sleeve part of the bottom part of the bag body, and is wrapped around the sleeve by a tie ring. The tightening ring groove on the outer surface of the joint is formed tight, because the end of the socket is covered with metal material and forms a ring-shaped stop lip, so that the tightening ring can be restricted by the stop lip. The positioning is used to avoid the phenomenon that the sleeve part slips off the ring member due to the increase of pressure inside the bag body, so as to achieve the tight fit of the air bag unit, which helps to improve the durability and practicability of the structure.

Description

Structure of car shock absorbers

This creation is about a shock absorber, especially a structure of a car shock absorber.

According to the current common vehicle air-cushion shock absorber structure, it is mainly connected with a rubber air bag on a shock absorber cylinder, and the upper and lower ends of the rubber air bag form a sleeve part, and then the rubber air bag is attached to the rubber air bag. 2. An upper seat and a lower seat are set in each group of the piercing parts at the lower ends, and are fastened to the outside of the piercing part by using a tie ring, and then the upper seat and the lower seat are fastened and fixed, and the upper seat and the lower seat are combined with the The state of the upper and lower ends of the rubber airbag, and the distance between the upper and lower seats can be changed relatively, so as to drive the airbag to compress or stretch, and then cooperate with the air filled inside the airbag, it can be used when the vehicle is running. To achieve the effect of buffering and shock absorption.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some deficiencies, and the main reasons are as follows: when the rubber airbag is tightened by a tie ring outside the sleeve portion, the sleeve portion and the tie ring are only separated from each other. There is a simple tightening state. When the rubber air bag is inflated, the rubber air bag will expand outward due to the gradual increase in the internal pressure, and pull the sleeve part of the rubber air bag, causing the sleeve part to slip off the ring. In this case, the cushioning and shock absorption effect of the rubber airbag is lost, which is the lack of use of the conventional air-cushion shock absorber, and it is necessary to improve it.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, and finally got a practical creation.

The technical problem to be solved by the present creation is to provide a structure of an automobile shock absorber in view of the above-mentioned deficiencies in the prior art.

The structure of the above-mentioned automobile shock absorber, the shock absorber includes a shock absorber cylinder and an air bag unit, the outer diameter of the shock absorber barrel is provided with a threaded section, and a buffering and retracted mandrel is arranged at the top of the shock absorber barrel, the The air bag unit has a bag body, a top cover and a base assembled on the upper and lower ends of the bag body, the upper end of the bag body has a necking part, and the necking part is an annular convex part extending outward, the The inside of the ring convex part is covered with a metal material, the lower end of the bag body forms a socket part, the outer diameter of the socket part is concavely provided with a tightening ring groove, and is matched with a bunch of rings to tighten the ring, and The end of the socket is covered with a metal material to form a stop lip, a hole is formed at the center of the top cover to pass through the mandrel, and the outer periphery of the top cover is rolled inward to form a snap ring The center of the base is provided with a combination hole with an internal thread, and the screw lock is set on the threaded section of the shock-absorbing cylinder. The eccentric part of the base is provided with an inflatable flow channel, and the bottom of the base is protruded outwardly with a against the ring.

Preferably, an upper seat body is sleeved along the mandrel above the top cover, and an outer thread section is provided on the outer diameter of the mandrel, and the outer thread section is matched with a nut, and then the nut is pressed against it. By limiting the upper body.

Preferably, an inner diameter surface of the top cover is provided with a ring groove, and an O-ring is embedded in the ring groove.

Preferably, the inner diameter surface of the combination hole of the base is provided with a ring groove, and an O-ring is embedded in the ring groove.

Compared with the effect of the prior art: the top cover of the airbag unit is fixed on the ring convex part of the upper end of the bag body by the peripheral snap ring part, and the base is assembled on the sleeve of the bottom part of the bag body and the tightening ring groove on the outer surface of the socket part is used to form a tightening ring, and because the end of the socket part is further covered with metal material and forms a ring-shaped stop lip, so that the The restraining ring member can indeed be restricted and positioned by the blocking lip, so that when the airbag unit is inflated, the phenomenon that the sleeve portion is slipped from the ring member due to the increase of the internal pressure of the airbag body can be avoided. The tight fit of the airbag unit helps to improve the durability and practicability of the structure.
