Description
Technical field
The present invention relates to the automobile brake chamber technical field, particularly a kind of double-piston energy storage spring brake chamber and single chamber piston type brake chamber.
Background technique
Brake chamber can be divided into energy storage spring brake chamber and single chamber brake chamber two big classes.
Energy storage spring brake chamber is the two-chamber brake chamber, has the inflation and two gas circuits of exitting concurrently, produces active force through inflation and venting, is used for wheel braking.The inflation braking is used for service brake, and the venting spring braking is used for stopping brake and emergency braking.Be widely used in now all kinds of trucies in, trailing wheel braking.
Single chamber brake chamber is commonly called as preceding air chamber, produces active force through inflation, is used for service brake.Now generally be applied to the front wheel brake of all kinds of trucies.
As shown in Figure 1, existing energy storage spring brake chamber is that upper gas chamber and lower chamber two large divisions form.Upper gas chamber is used for service brake, and lower chamber is used for stopping brake.Originally the lower chamber of product is the piston motion type, and lower chamber is the epithelium gas type.This product uses demonstration for many years through market, have following shortcoming:
1. the epithelium badly broken accounts for 75% of whole proportion of goods damageds.
2. lack working life, normal use can only have about 6 months.
3. safety coefficient is low.Epithelium is a rubber product, in it moves repeatedly, can produce distortion, aging and phenomenon that moment breaks, thereby loses efficacy the moment that causes braking.
4. gas leakage link is many.Upper gas chamber is stepped up by anchor ear by aluminium lid, epithelium, loam cake butt joint again.Be soft contact wherein, lifting surface area is little, thereby uses the back epithelium deliquescing to produce the gap, causes the generation of gas leak phenomenon.
5. manufacturing efficiency is low.Because its accessory is various, mostly assembly process is manual operation, and personnel selection is many, and speed is slow, so production process is difficult to control, causes defect rate high.
The situation of single chamber brake chamber is identical with the upper gas chamber of energy storage spring brake chamber with shortcoming.
Summary of the invention
The technical problem that the present invention will solve is: a kind of double-piston energy storage spring brake chamber and single chamber piston type brake chamber are provided, simplify the structure of brake chamber, improve the reliability and the working life of brake chamber.
