Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has the rubber diaphragm of braking air chamber that location, good sealing effect, efficiency of assembling and quality are high when assembling with air chamber in air chamber.
In order to solve the problems of the technologies described above, technological scheme of the present invention is to provide a kind of rubber diaphragm of braking air chamber, comprise bottom and skew wall, skew wall top extends outwardly through arc shaped surface and is connected with lip limit, it is characterized in that: described arc shaped surface lower surface or described skew wall upper end outer surface are provided with position structure.
Preferably, when rubber diaphragm of braking air chamber to be located in the air chamber of brake chamber in air chamber, in described locating ring structure and described air chamber, air chamber skew wall internal surface is close to.
Preferably, described position structure is the positioning ring of loop configuration.
Preferably, described position structure is the positioning block of whole circle equidistant placement.
Preferably, described positioning block is point-like, square or strip.
Device provided by the invention overcomes the deficiencies in the prior art, on air chamber assembly line, the position structure of rubber diaphragm of braking air chamber is close to air chamber skew wall internal surface in air chamber, air chamber in rubber diaphragm of braking air chamber and air chamber is located automatically, and can not relative displacement be there is therebetween, No leakage, good sealing effect, also improves efficiency of assembling and assembly quality simultaneously.
