Description
Technical field
Brake system of car vacuum booster technical field is the utility model is related to, more particularly to one kind is used for brakes
Vacuum booster for vehicle brake valve body.
Background technology
Automobile vacuum booster is widely used brake power assisting device from light-duty vehicle to compact car, its general position
Between brake pedal and master cylinder, for ease of installation, a component is generally synthesized with master cylinder, a part for master cylinder is deep into
In vacuum booster housing.
Vacuum booster mainly by servo vacuum air chamber and control valve group into, control valve is made up of air valve and vacuum valve,
Air valve is solidly installed with control valve follower, and control valve follower is temporarily transferred whole fork and is connected with brake treadle mechanism.Vacuum valve is installed
It is general that front/back cavity is divided into using rubber diaphragm and completely cut off with ambient atmosphere with the valve body of air valve, it is then turned on air valve
Door makes back cavity pour into air, using producing power-assisted in the presence of ante-chamber and back cavity draught head.
Have on valve body and be used to connect ante-chamber and the passage of control valve, and for connecting the passage of back cavity and control valve,
Although the material of valve body is REINFORCED PET plastics, it is also integrally formed using injection mold, and the presence of passage can reduce valve body
The intensity of channel part.
Utility model content
The utility model is in order to solve the technical problem of traditional valve body low intensity, there is provided a kind of automobile brake vacuum helps
Power device valve body.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
Vacuum booster for vehicle brake valve body, it is made up of shell and cylindrical inner casing, passes through between the shell and inner casing
Four pieces of contiguous blocks link into an integrated entity；The boss for fixing rubber diaphragm is provided with the inwall of the inner casing；The boss will
The chamber of inner casing is every being divided into ante-chamber and back cavity；There is gap, the gap is connection ante-chamber and control between two pieces of adjacent contiguous blocks
The first passage of valve processed, the reinforcement being connected with the inner casing is provided with the first passage；The shell corresponds to the company
Connect the second channel that connection back cavity and control valve are provided with block.
Be further, the boss have two, it is symmetrically disposed in inner casing, and positioned at each two contiguous block it
Between；That side that the boss is located at the back cavity is provided with the boss being connected with the inner casing.
It is further that one end that the inner casing is located at the back cavity is provided with the reinforcement of a circle and the cage connection
Block.
It is further that the groove that a circle is used to install sealing ring is provided with the shell.
Compared with prior art, the beneficial effects of the utility model are：
1. the reinforcement installed in first passage adds the intensity of valve body first passage part, contiguous block adds valve body
The intensity of second channel part；
2. due to being riveting between rubber diaphragm and boss, so the boss at boss can increase the strong of boss
Degree；
3. the boss on inner casing not only acts as the purpose of increase intensity, the effect of connection inner casing and shell is also acted as.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.
Fig. 1 is the side view of the valve body disclosed in embodiment；

Fig. 3 is the top view of the valve body disclosed in embodiment；
Fig. 4 is A-A diagrammatic cross-sections in Fig. 3；
Fig. 5 is the upward view of the valve body disclosed in embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
The accompanying drawing of the present embodiment is referring to Fig. 1-5.
Vacuum booster for vehicle brake valve body, it is made up of shell 1 and cylindrical inner casing 2, passes through four between shell and inner casing
Block contiguous block 3 links into an integrated entity；Two boss 4 for fixing rubber diaphragm, the two boss are provided with the inwall of inner casing
It is symmetrically disposed in inner casing；Boss is by the chamber of inner casing every being divided into ante-chamber and back cavity；Have between two pieces of adjacent contiguous blocks
Gap, the gap are connection ante-chamber and the first passage 5 of control valve, and the reinforcement 6 being connected with inner casing is provided with first passage；
Shell corresponds to the second channel 7 that connection back cavity and control valve are provided with contiguous block.The reinforcement increase installed in first passage
The intensity of valve body first passage part, contiguous block add the intensity of valve body second channel part.
That side that boss is located at back cavity is provided with the boss 8 being connected with inner casing, due between rubber diaphragm and boss
It is riveting, so the boss at boss can increase the intensity of boss.
That one end that inner casing is located at back cavity is provided with a circle and the boss 9 of cage connection, and the boss not only acts as increasing
The purpose of reinforcement degree, also act as the effect of connection inner casing and shell
The groove 10 that a circle is used to install sealing ring is provided with shell.
A variety of modifications to these embodiments will be apparent for those skilled in the art, herein
The General Principle for moving justice can be real in other embodiments in the case where not departing from spirit or scope of the present utility model
It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein
Principle and the consistent most wide scope of features of novelty.
