Description
Technical field
This utility model belongs to vacuum booster technical field and in particular to a kind of front tray of vacuum booster.
Background technology
Vacuum booster is brake power assist unit in car and Light-duty Vehicle brakes, sucks empty when being worked using electromotor
This principle of gas, causes the side vacuum of booster, with respect to the pressure differential of opposite side normal air pressure, using this pressure differential
To strengthen retrothrust, to be formed and maintain the pressure differential of regulation for guarantee vacuum booster front/back cavity, close between front/back cavity
Envelope property is then most important, and the factor of impact vacuum booster front/back cavity sealing property has a lot, wherein double diaphragm vacuum boosters
Front tray Main Function hold front diaphragm, play stable and resilience effect, existing front tray is sometimes in resilience back and forth
During not in place, structure not science, can shift, need improve.
Content of the invention
For solving the above problems, the utility model discloses a kind of front tray of vacuum booster, delicate structure, resilience
Good, long service life.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of front tray of vacuum booster it is characterised in that：Including front tray body, described front tray body is circle
Shape, the longitudinal section of front tray body is continuous groove-like structure, is provided with valve hole, valve hole sets between front tray body
There is symmetrically arranged anti-rotation groove, valve hole is respectively provided on two sides with intercommunicating pore, the centrage of two intercommunicating pores and the angle of anti-rotation groove
Spend for 37 °.
As a kind of improvement of the present utility model, described groove-like structure is any in V-shaped groove, square groove and arcuate groove
One or any several combination.
As a kind of improvement of the present utility model, the quantity of described anti-rotation groove is two.
As a kind of improvement of the present utility model, described front tray body edges are provided with crimping.
As a kind of improvement of the present utility model, described front tray body is elastomer.
The beneficial effects of the utility model are：
A kind of front tray of vacuum booster described in the utility model, structure is simple, compact, reasonable, has strong support, with
The action of keep plate is consistent, and resilience is good, long service life.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Reference numerals list：
1st, front tray body, 2, valve hole, 3, anti-rotation groove, 4, intercommunicating pore, 5, crimping.
Specific embodiment
With reference to the accompanying drawings and detailed description, it is further elucidated with this utility model it should be understood that following specific embodiment party
Formula is merely to illustrate this utility model rather than limits scope of the present utility model.It should be noted that making in describing below

Be directed towards or the direction away from particular elements geometric center.
As illustrated, a kind of front tray of vacuum booster described in the utility model, including front tray body 1, described
Front tray body 1 is circle, and the longitudinal section of front tray body 1 is continuous groove-like structure, is provided with valve body between front tray body 1
Through hole 2, valve hole 2 is provided with symmetrically arranged anti-rotation groove 3, and valve hole 2 is respectively provided on two sides with intercommunicating pore 4, two connections
The centrage in hole 4 is 37 ° with the angle of anti-rotation groove 3.
A kind of front tray of vacuum booster described in the utility model, is the support of the front diaphragm of double diaphragm vacuum boosters
Disk, front tray body 1 holds front diaphragm, and front diaphragm is elastomer with front tray body 1, during use, before valve body drives front diaphragm
After move, pallet is followed and is moved, and this utility model structure is simple, compact, reasonable, has strong support, and the action with keep plate keeps
Unanimously, resilience is good, long service life.
Groove-like structure described in the utility model is V-shaped groove, in square groove and arcuate groove any one or arbitrarily several
The combination planted, rational in infrastructure, elasticity is good.
The quantity of anti-rotation groove 3 described in the utility model is two, can block valve body, will not rotate.
This utility model is provided with crimping 5 at described front tray body 1 edge, and support force is strong, impulse- free robustness, and gliding smoothing is suitable
Freely, improve work efficiency.
Technological means disclosed in this utility model scheme are not limited only to the technological means disclosed in above-mentioned embodiment, also
Including the technical scheme being made up of above technical characteristic combination in any.
