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 T-shaped shell and inner disc, the inner disc is located at the enclosure,
And the bottleneck of the shell is connected to by four pieces of contiguous blocks；The inner disc is by the chamber of shell every being divided into ante-chamber and back cavity；
There is gap, the gap is connection ante-chamber and the first passage of control valve, and the shell is corresponding between two pieces of adjacent contiguous blocks
Connection back cavity and the second channel of control valve are provided with the contiguous block；That one end that the inner disc is located at the back cavity has
One annulus, the inwall of the annulus corresponds to is provided with boss at the first passage.
It is further that the shell is in being provided with several reinforcements on the inwall of the ante-chamber, the one of the reinforcement
The shell is stretched out at end, and the other end extends to the inner disc.
It is further that one end that the reinforcement stretches out the shell has guiding surface.
It is further that one end that the contiguous block is located at the ante-chamber is provided with the recessed of circle installation rubber diaphragm
Groove.
It is further that the bottleneck of the shell is provided with the annular groove that a circle is used to install sealing ring.
Compared with prior art, the beneficial effects of the utility model are：
1. inner disc is connected to the bottleneck of shell by contiguous block, the intensity of contiguous block not only valve body first passage part,
Also increase the intensity of valve body second channel part；
2. annulus adds the length of first passage, boss adds the intensity of first passage.

Groove 4；Inner disc is by the chamber of shell every being divided into ante-chamber 5 and back cavity 6；There is gap, the gap between two pieces of adjacent contiguous blocks
For connection ante-chamber and control valve first passage 7, shell correspond to be provided with contiguous block connection back cavity and control valve second lead to
Road 8.Inner disc is connected to the bottleneck of shell by contiguous block, the intensity of contiguous block not only valve body first passage part, also increases
The intensity of valve body second channel part.
That one end that inner disc is located at back cavity has an annulus 9, and the inwall of annulus, which corresponds to, is provided with reinforcement at first passage
Block 10.Annulus adds the length of first passage, and boss adds the intensity of first passage.
It is further that for shell in being provided with several reinforcements 11 on the inwall of ante-chamber, shell is stretched out in one end of reinforcement,
The end has guiding surface 12, and the other end extends to inner disc.
It is further that the bottleneck of shell is provided with the annular groove 13 that a circle is used to install sealing ring.
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
