Description
Technical field
This utility model is related to a kind of auto-parts, specially a kind of vacuum booster.
Background technology
Which kind of effect each piece of pedal of underfooting possesses respectively is a key, and this can drum in Che Shi coach, because
It is not only the key of starting for it, main is then closely bound up with safety.It is provided with true between pedal and master cylinder
Empty booster, it can provide bigger strength to act on push rod so that driver easily can step on pedal thus promoting system
Piston in dynamic master cylinder moves ahead.
Common booster is only provided only with an airway, how epithelium discontinuity during power-assisted work, inside booster
Consume frottage greatly Deng parts, have impact on the service life of booster, and single-pass air flue booster air inflow is little, power-assisted is reacted
Time is long, and brake hard is slow.
For solving the above problems, therefore it is proposed that a kind of vacuum booster.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of vacuum booster.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme：
A kind of vacuum booster of this utility model, including servo vacuum air chamber, master cylinder and control device, described vacuum
Servo air chamber passes through control device being connected with master cylinder, control device include rubber reaction plate, epithelium baffle plate, epithelium,
Booster push rod, vacuum valve and air cock, described rubber reaction plate is arranged on servo vacuum air chamber central authorities and booster push rod
Afterbody contacts, and described epithelium is fitted tightly on epithelium baffle plate and connects epithelium return spring, and described booster push rod is provided with
Air cock, described vacuum valve is corresponding with vacuum valve seat, described booster push rod, air cock respectively with booster return spring and
Valve spring connects, and described master cylinder top is communicated with fluid reservoir, is provided with true in described servo vacuum air chamber external vacuum pipe
Empty check valve.
Further, described fluid reservoir center of inside is provided with ripple level sensor top and opens up air vent.
Further, described vacuum check valve connects vacuum pump and communicates with vacuum tube and with servo vacuum air chamber, and surface is
Spherical and one end connects back-moving spring.
Further, described booster push rod rear end surface adsorbs brake pad sensor.
Further, at described air cock and ambient inlet air mouth, foam cleaner is installed.
The beneficial effect that this utility model is reached is：By arranging ripple level sensor in fluid reservoir, when braking pad wear
When, master cylinder can push brake cylinder to the brake fluid in fluid reservoir, in order to compensate braking epithelium before and after produce stroke,
On the premise of there is not seepage brake fluid in brakes, by brake fluid fluid reservoir liquid level just can determine whether brake disc,
The abrasion condition of piece, vacuum check valve adopts globe valve to connect the pattern of back-moving spring, check valve and pipe in long-term switch closure
Occur in that abrasion in mouthful friction, just have more volumes and be stuck in outside the mouth of pipe, back-moving spring decreases vacuum pump cannot will be unidirectional
Valve inhales the probability opened it is ensured that booster normal work, prevents brake pedal hardening, greatly improves the braking ability of vehicle.

Specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
Embodiment 1
As shown in figure 1, a kind of vacuum booster, including servo vacuum air chamber 1, master cylinder 2 and control device, described true
Empty servo air chamber 1 passes through control device being connected with master cylinder 2, control device include rubber reaction plate 6, epithelium baffle plate 7,
Epithelium 8, booster push rod 14, vacuum valve 15 and air cock 13, described rubber reaction plate 6 is arranged in servo vacuum air chamber 1
Centre is contacted with booster push rod 14 afterbody, and described epithelium 8 is fitted tightly on epithelium baffle plate 7 and connects epithelium return spring 16,
Described booster push rod 14 is provided with air cock 13, and described vacuum valve 15 is corresponding with vacuum valve seat 12, described booster push rod
14th, air cock 13 is connected with booster return spring 10 and valve spring 9 respectively, described master cylinder 2 top and fluid reservoir 3 phase
Logical, it is provided with vacuum check valve 4 in described servo vacuum air chamber 1 external vacuum pipe.
Described fluid reservoir 3 center of inside is provided with ripple level sensor 17 top and opens up air vent 18, the storage of monitoring brake fluid
Amount, when liquid level is less than lower limit, gives a warning, described vacuum check valve 4 connect vacuum pump with vacuum tube and with servo vacuum gas
Room 1 communicates, and surface is spherical and one end connects back-moving spring, prevents vacuum check valve 4 from just wearing and tearing stuck mouth of pipe impact booster
Often work, described booster push rod 14 rear end surface adsorbs brake pad sensor 5, in brake pad part wears to extreme position
When, sensor cuts off and then triggers warning immediately, improves the safety of braking, installs at described air cock 13 and ambient inlet air mouth
Foam cleaner 11, filters the impurity such as dust, the sandy soil of in the air, reduces the infringement to parts for the harmful substance.
It should be noted that：An epithelium 8 equipped with booster push rod 14 is had to divide cavity inside this kind of vacuum booster
For two parts, a part is communicated with air, and another part is connected with engine air inlet tube by pipeline, when being worked using electromotor
Suck this principle of air, cause the side vacuum of booster, with respect to the pressure differential of opposite side normal air pressure, using pressure
Power difference is forcing thrust.Even if there is the pressure differential of very little on epithelium 8 both sides, because epithelium 8 area is very big, still can produce very big
Thrust promotes epithelium 8 to the little end motion of pressure, thus producing the required power-assisted of braking.
Finally it should be noted that：The foregoing is only preferred embodiment of the present utility model, be not limited to this
Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art
For, it still can be modified to the technical scheme described in foregoing embodiments, or to wherein some technical characteristics
Carry out equivalent.All of the present utility model spirit and principle within, any modification, equivalent substitution and improvement made etc., all
Should be included within protection domain of the present utility model.
