Description
Technical field
It the utility model is related to a kind of automobile brake chamber, more particularly to a kind of automobile brake with functions of waterproof and dustproof
Air chamber.
Background technology
Automobile brake chamber has two kinds, only single air chamber of running braking function by function, is provided simultaneously with driving system
The energy storage spring brake chamber of dynamic function and parking braking function, no matter which kind of brake chamber, there is running braking function, drive a vehicle
Braking is filled with compressed air by the service brake intracavitary closed makes epithelium turn up, and compressed air can be changed into mechanical energy, pushed away
Dynamic push rod disk component is released, and power output is applied on the brake in wheel hub, makes brake operation, realizes braking, service brake
Releasing is all by releasing service brake cavity pressure, drives push rod disk component return to realize by the return spring in brake, is
Returning quickly is realized, is not dragged, return spring chamber must communicate with air.
Prior art is realized by outputing several passages on front cover component periphery, refers to Fig. 1, automobile system
Room of taking offence is fixed on the inside of axle hub by front cover component 1, and during running car, C chambers keep being filled with compressed air, brute spring
10 are compressed, and D chambers volume reduces, and D chamber airs enter B chambers by guide pin bushing plug screw 4, are discharged into air by control valve filter core, push away
Bar disk component 9 is in contact in brake returning place force effect lower push-rod disk component with middle body component 3, A chambers volume increase, due to protecgulum
Passage E is provided with component 1, air enters A chambers by passage E；
During service brake, B chambers are filled with compressed air, the increase of B chambers volume, and epithelium 2 is overturn to the left, and A chambers are compressed, A intracavitary
Gas enters external environment by passage E.
During parking braking, C chamber pressure releases, brute spring 7 promotes piston component 6, drives guide pin bushing plug screw 4, epithelium 2, push rod disk
Component 9 moves to left, and is braked being realized on Braking to brake, identical when A chambers operating mode is with service brake.
Therefore, when brake chamber releases parking braking and during service brake return, air chamber ambient air passes through passage E
Push-rod assembly chamber A is directly entered, nearer with road surface because air chamber is arranged in vehicle bridge on the inside of wheel, air chamber week in running car
Side dust is larger, and push rod disk assembly chambeies can bring dust into air during service brake return, adsorb in push rod disk component and epithelium
Surface, accumulate over a long period and accelerate correlated parts corrosion, epithelium aging in push rod disk assembly chambeies, if paddling service brake when travelling,
Water is directly sucked into push rod disk assembly chambeies, because water resistance is far longer than vapour lock when braking again, braking effect can be weakened significantly,
Brake fade is even resulted in, increases dangerous situation probability of happening.

Cleaner rear is connected, and the front cover component, epithelium and middle body component are fixedly linked by clip, the front cover component and skin
The push rod disk assembly chambeies of closing are formed between film, the push rod disk component is located in push rod disk assembly chambeies.
The above-mentioned automobile brake chamber with functions of waterproof and dustproof, wherein, described piston component one end and guide pin bushing plug screw
Connected again with middle body component slippage after being fixedly connected, the release bolt assembly is enclosed in piston component by brute spring.
The utility model contrast prior art has following beneficial effect：It is provided by the utility model that there is water proof and dust proof work(
The automobile brake chamber of energy, by adding the airway tube being connected with air cleaner rear on front cover component, is not required to preceding
The passage communicated with air is directly set on cap assemblies, the closure transformation of push rod disk assembly chambeies is realized, so as to eliminate push rod
The negative effect that disk assembly chambeies passage is brought, the sealing effect of automobile brake chamber is improved, extends making for automobile brake chamber
Use the life-span.
