Abstract
The utility model provides a self-control and leaking-proof three-way for an automobile brake system, comprising a three-way body, a piston, a location spring, a gasket, an oil (gas) outlet connector and a V-shaped chute in the three-way body. When a brake line and a leather cup break and the oil (gas) overflows, the utility model can automatically control with the actions of the pressure and the counter pressure, so the piston can be pushed to the oil (gas) leaking side of the three-way body, and therefore, the oil (gas) leaking side can be effectively blocked. Therefore, the utility model can assure the normal brake of the other wheels and can accomplish the purpose of safe driving. The utility model has the advantages of simple structure, easy fabrication, low cost, convenient installation and operation.
Description
The utility model relates to a kind of automatic control leakproof threeway that is used for automobile brake.
The normal through type of using three is connected with two kinds on the gentle type of oil type in the automobile brake pipeline, and they can make brake noise (gas) normally lead to certain position, play the effect of wheel braking all around.
In the running car often since be subjected to friction, aging, oil touches etc. influences, wheel cylinder pipeline and leather cup easily break under certain pressure, thereby brake noise (gas) is flowed out by rent, make brake piping lose pressure, and relate to and the pipeline and the leather cup that have influence on other normal wheels can not be braked because of losing pressure, so cause the car load brakeless.Both made running route good, chaufeur is experienced, all swings shelves, wall built-up, trimming slope unavoidably, meets danger, road, curved many, also can cause the grave accident of personal death and car, goods.
The purpose of this utility model is that at the indeterminable problem of above-mentioned through type threeway providing a kind of can be used for the automatic control leakproof threeway of automobile brake under the effect of pressure and counter pressure.It not only has the effect of through type threeway, and can be when automobile brake oil (gas) spill and leakage, and the side with spill and leakage oil (gas) bottles up automatically, guarantees the normal brake application of other wheel, improves traffic safety.
There is piston at the middle part of the utility model three-way body, left and right sides inclined trough surface " eight " font outside piston is that place, three-way body oil-feed (gas) vestibule bottom is provided with, piston contacts with retainer spring, fuel-displaced (gas) connector contacts with retainer spring, and securely links into an integrated entity with fuel-displaced (gas) vestibule of three-way body.
The piston head of the utility model automatic control leakproof threeway has rubber cradle, and this top is the taper round end, and it equates with the diameter of bore of fuel-displaced (gas) connector.There is metal washer at fuel-displaced (gas) vestibule and fuel-displaced (gas) connector place at three-way body.
During automobile brake, the pipeline that connects first side when the left and right sides of three-way body fuel-displaced (gas) is during with leather cup spill and leakage oil (gas), and the pipeline of this side promptly loses pressure, and the line pressure of opposite side is therefore decline also.Brake noise (gas) can produce a kind of counter pressure in backflow, under this counter pressure effect, can push the piston of the utility model automatic control leakproof threeway to this side, this side of spill and leakage oil (gas) is bottled up automatically, thereby guarantee the normal brake application of other wheel, reach the purpose of traffic safety.
The utility model is described in further detail below in conjunction with the accompanying drawing example.
Fig. 1 is the front view of the utility model negative thread (oil type) automatic control leakproof threeway;
Fig. 2 is the section-drawing of Fig. 1;
Fig. 3 is the front view of the utility model outside thread (gas type) automatic control leakproof threeway;
Fig. 4 is the section-drawing of Fig. 3.
Example of the present utility model comprises three-way body (1), piston (2), retainer spring (4), rubber cradle (5), metal washer (6), the skewed slot (3) that fuel-displaced (gas) connector (7) and place, three-way body (1) oil-feed (gas) vestibule bottom are provided with.
Two kinds on automatic control leakproof three reduction of fractions to a common denominator oil types of the present utility model and gas type, removing the oil type threaded joint is negative thread, and gas type threaded joint is outside the outside thread, and other structure is all identical.
Three-way body of the present utility model (1) is the vestibule of brake noise (gas) turnover, and its oil-feed (gas) vestibule and fuel-displaced (gas) vestibule weld or casting with metal pipe material.This three-way body (1) be negative thread or outside thread into and out of vestibule joint screw thread.
Piston (2) is positioned at the middle part of three-way body (1), makes with materials such as hard light plastic or aluminum alloy or spheroidal graphite alloys.Rubber cradle (5) is arranged at the top of this piston (2), and it seals.
The top of piston (2) is the taper round end, and it equates with the diameter of bore of fuel-displaced (gas) connector (7).After piston (2) once bottles up, can restrain the return effect of retainer spring (4), reach the purpose of braking at other wheel continuously.
In left and right sides skewed slot (3) " eight " font outside piston (2) is that the place, oil-feed (gas) vestibule bottom of three-way body (1) is provided with, it is the passage that brake noise (gas) leads to fuel-displaced (gas) connector (7) both sides.
Piston (2) contacts with retainer spring (4), and spring (4) can keep the center position of piston (2) at three-way body (1), thereby guarantees the both sides of brake noise (gas) by outer " eight " font skewed slot (3) fuel-displaced until leading to (gas) connector (7).
Fuel-displaced (gas) connector (7) contacts with retainer spring (4), and securely links into an integrated entity with fuel-displaced (gas) vestibule of three-way body (1).
Fuel-displaced (gas) vestibule and fuel-displaced (gas) connector (7) of three-way body (1) have been located metal washer (6), are used for sealing and fastening.The screw thread of fuel-displaced (gas) connector (7) is negative thread or outside thread.
The utility model automatic control leakproof threeway simple in structure, easy to manufacture, cost is low, installs, and is easy to use, is applicable to the automobile of oil or compressed air brake, and it can prevent and bottle up the spill and leakage of brake noise (gas) effectively, guarantees traffic safety.
