Abstract
The utility model discloses a kind of brake chamber driving chamber rubber diaphragms, include bottom and side wall, the upper end of the side wall, which extends outwardly, is connected with lip, it is characterised in that：The lip lower end is set as the arc binding face of indent, and ecto-entad is successively arranged first of seal line and second line of seal on the arc binding face.The utility model is structurally reasonable, easy to assembly, and diaphragm is bonded closely with middle shell in assembling process, and sealing effect is good.
Description
Technical field
The utility model relates to a kind of improvement of brake component invention more particularly to a kind of brake chamber driving chamber rubber membranes
The improvement of piece is invented.
Background technique
Brake chamber is made of end cap, clip, diaphragm and middle shell, traditional diaphragm sealing surface mainly pass through middle shell with
Between diaphragm by force squeeze be sealed, be easily damaged diaphragm influence sealing performance, and conventional film piece assembly mainly by diaphragm with
The contact of middle housing sidewall is limited, and is carried out by the way that employee is hand steered to just, however easily leads to pressure when the hand steered operation error of employee
Wound, and it is inclined to be easy dress.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of easy to assembly, close
The good brake chamber driving chamber rubber diaphragm of envelope property.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：This kind brakes gas
Room driving chamber rubber diaphragm, includes bottom and side wall, the upper end of the side wall, which extends outwardly, is connected with lip, and feature exists
In：The lip lower end is set as the arc binding face of indent, on the arc binding face ecto-entad be successively arranged first it is close
Seal line and second line of seal.
The lip is pressed between the end cap of brake chamber and middle shell, and the port of the middle shell is equipped with and the arc
The flange that shape binding face matches, and flange is equipped with the groove to match with first of seal line.
The chamber rubber diaphragm the utility model has the beneficial effects that improved brake chamber is driven a vehicle, the arc binding face of diaphragm
Flange with middle shell is close-fitting, and two components compactness are preferable in assembling process；Increase two seals line simultaneously, makes diaphragm
It is more preferable with the air-tightness effect of middle shell, and increase stability of the diaphragm in middle shell.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the A enlarged drawing of the utility model Fig. 1.
Fig. 3 is the installation diagram of the utility model and middle shell.
Specific embodiment
Attached drawing illustrates the structure of the utility model, further illustrates it in relation to details in conjunction with attached drawing below.The braking
Gas chamber driving chamber rubber diaphragm 1, includes bottom 11 and side wall 12, the upper end of the side wall 12, which extends outwardly, is connected with lip
13, lip 13 is pressed between the end cap of brake chamber and middle shell 2, and 13 lower end of lip is set as the arc fitting of indent
Face 14, ecto-entad is successively arranged first of seal line 15 and second line of seal 16 on the arc binding face 14；The middle shell
The port of body 2 is equipped with the flange 21 to match with the arc binding face 14, and flange 21 is equipped with and seals with described first
The groove that line 15 matches.
When work, when diaphragm 1 is put into middle 2 rigging position of shell naturally, the arc binding face 14 of diaphragm 1 can be with middle shell
2 flange, 21 position nature correcting guarantees that diaphragm 1 and middle shell 2 are concentric, is not in unilateral case；When end cap is by hydraulic press pressure
Under the action of power, end cap, diaphragm 1, middle shell 2 are squeezed by force and are assembled to together, first of seal line 15 is compacted to middle shell 2
After in groove, guarantee that diaphragm 1 will not answer pulling force effect and pull out in use, have stronger connection, while having at this
Sealing effect；After end cap, diaphragm 1, middle shell 2 are assembled together, the flange of the second line of seal 16 of rubber and middle shell 2
21, which carry out fitting, forms sealing, and such first of seal line 15 forms dual-seal with second line of seal 16.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection scope.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
