Abstract
The utility model relates to a double air cavity type braking chamber which comprises a shell body which is composed of a front cover and a back cover, wherein a push rod is arranged in the shell body; the front end of the push rod extends out of the front cover; the back end of the push rod is fixedly connected with a push rod disk and abutted with a first leather diaphragm fixedly connected with the back cover by the push rod disk; a restoring spring is sheathed on the push rod; one end of the restoring spring is abutted with the front cover, and the other end is abutted with the push rod disk; a front pressurization cavity is formed in the first leather diaphragm; the back cover is fixedly connected with a second leather diaphragm; a back pressurization cavity is formed in the second leather diaphragm; a front cavity inlet and a back cavity inlet respectively communicated with the front and the back pressurization cavities are arranged on the back cover; a filler block is clamped between the second leather diaphragm and the first leather diaphragm. The utility model has the advantages that the structure of the air chamber is simplified and the manufacture cost is greatly reduced because the air braking chamber replaces the strong spring braking. The utility model has the advantage of long service life, the service life of a strong spring is 100 to 150 thousand times in general and the service life of the leather diaphragm is larger than one million times in general.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of pair of air-chamber pattern arrester.
Background technique
The parking braking of traditional energy storage spring brake chamber is enabled to realize by the brute spring of its back cavity, for satisfying the requirement of braking thrust output, the brute spring size is all bigger, cause whole device relatively heavy, because brake chamber is to hang to install on vehicle bridge, deadweight directly influences self frequency and amplitude with the indefinite automobile vibration of the moderately gusty air of advancing, and obviously more heavily to the stability of self, the dynamic characteristic of car load is unfavorable more.In addition, adopt spring braking, working life is short, the cost height.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of rational in infrastructure, two air-chamber pattern arresters that using effect is good are provided.
The utility model solves the technological scheme that its technical problem adopts: this pair of air-chamber pattern arrester, comprise the housing of forming by protecgulum, bonnet, be provided with push rod in the housing, this push rod front end stretches out outside the protecgulum, its rear end is connected with the push rod dish, and is butted on first epithelium that is fixed in bonnet by this push rod dish; Be arranged with Returnning spring on the push rod, this Returnning spring one end is butted on protecgulum, and the other end is butted on the push rod dish; Pressurizing chamber before forming in first epithelium, described bonnet also is connected with second epithelium, forms the back pressurizing chamber in this second epithelium, has the ante-chamber import, the back cavity import that communicate with forward and backward pressurizing chamber respectively on the bonnet; Accompany pad between second epithelium and first epithelium.
The effect that the utility model is useful is: the utility model parking braking adopts the mode of closed compression air to realize, do not re-use brute spring, thereby overall structure is reduced greatly, similar with single barrier film air chamber, weight also greatly alleviates, less than half of energy storage spring brake chamber.Replace the brute spring braking by the gas arrester, air chamber structure is simplified greatly, and manufacture cost reduces significantly.Long service life, the brute spring life-span, generally 10-15 ten thousand times, the epithelium life-span was generally greater than 1,000,000 times, in addition, in the vehicle traveling process, brute spring is in confined state, and whole air chamber is in always and is subjected to tension state, after being substituted, during automobile normal running, non-compressed air in the air chamber, air is in unloading condition, and air chamber is greatly enhanced working life.

Description of reference numerals: push rod 1, back cavity import 2, fastening piece 3, protecgulum 4, spring collar 5, Returnning spring 6, clip 7, spacer ring 8, the first epitheliums 9, pad 10, the second epitheliums 11, bonnet 12, clamping bolt 13, ante-chamber import 14, push rod dish 15.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This pair of air-chamber pattern arrester, comprise the housing of forming by protecgulum 4, bonnet 12, protecgulum 4, bonnet 12 joints are by clip 7 bandings, be provided with push rod 1 in the housing, this push rod 1 front end stretches out outside the protecgulum 4, its rear end is connected with push rod dish 15, and is butted on first epithelium 9 that is fixed in bonnet 12 by this push rod dish 15; Be arranged with Returnning spring 6 on the push rod 1, these Returnning spring 6 one ends are butted on protecgulum 4, and the other end is butted on push rod dish 15; Protecgulum 4 is provided with spring collar 5, and this spring collar 5 has boss, and Returnning spring 6 is placed on the boss.Pressurizing chamber before forming in first epithelium 9, bonnet 12 also is connected with second epithelium 11, forms the back pressurizing chamber in this second epithelium 11, has the ante-chamber import 14, the back cavity import 2 that communicate with forward and backward pressurizing chamber respectively on the bonnet 12; Second epithelium 11 and 9 of first epitheliums accompany pad 10.Protecgulum 4, bonnet 12 joints are lined with spacer ring 8, and these spacer ring 8 two ends cooperate with protecgulum 4, bonnet 12 respectively, with the two ends clamping of first epithelium 9, second epithelium 11.This arrester is fixed on the automobile support by fastening piece 3.Clip 7 is by clamping bolt 13 lockings.
During use, from back cavity import 2 input pressurized air, second epithelium 11 is propped up pad 10, then promote push rod dish 15 again, drive push rod 1 afterwards and move forward, the final realization braked.Simultaneously, also can promote first epithelium 9, drive push rod 1 afterwards and move forward, realize braking from ante-chamber import 14 pressurized air.Like this, two air cavity structures can increase retrothrust, and using effect is better.
