Description
Technical field
The utility model relates to automobile brake field, relates to specifically a kind of vacuum line structure of brake system of car.
Background technology
In the brake system of automobile, the traditional method that vacuum booster obtains vacuum is: be directly connected with vacuum source (induction maniflod, vacuum pump) by a vacuum lamp.Along with car speed is more and more higher, brake system is as safety system, also more and more higher to the requirement of performance.Induction maniflod is as vacuum source, and the too low problem of degree of vacuum has affected deceleration and stopping performance to a certain extent.The problem of simultaneously only having the automobile in single vacuum source to exist power-assisted to reduce and lack in the situations such as vacuum source inefficacy and lower long slope, it certainly will affect vehicle driving safety.Under these problems, people urgently wish that a kind of vacuum is strengthened and supply pipeline structure to improve on orthodox car vacuum source degree of vacuum lower, the problem that vacuum source is single.
Utility model content
The purpose of this utility model is to address the above problem, and a kind of vacuum line structure of brake system of car is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of vacuum line structure of brake system of car, comprise and strengthen pipeline and supply pipeline, vacuum air storage tank, strengthen pipeline and comprise reinforced pipe and vacuum pressure charging valve, vacuum pressure charging valve has three interfaces, an interface is communicated with inter cooling pipeline, between this interface and inter cooling pipeline, be provided with a check valve A, an interface is communicated with induction maniflod interface, an interface is communicated with one end of reinforced pipe, other one end of reinforced pipe is communicated with a threeway, this threeway is communicated with other two pipelines, the check valve B of leading up to is communicated to vacuum air storage tank, the check valve C of leading up to is communicated to vacuum booster interface, supply pipeline comprises supply pipe, and supply pipe one end is communicated with induction maniflod interface, and one end is communicated to vacuum air storage tank by a check valve D in addition.
Vacuum pressure charging valve is made up of Venturi tube and check valve, and the import of check valve connects reinforced pipe one end, and the outlet of check valve connects the trunnion portion low-voltage interface of Venturi tube, and the import of Venturi tube connects inter cooling pipeline, and the outlet of Venturi tube connects induction maniflod.
The beneficial effects of the utility model are: 1, by the effect of vacuum pressure charging valve, vacuum booster can obtain than from also high degree of vacuum of induction maniflod (vacuum source), improves automobile brake perfrmance.2,, by the effect of vacuum air storage tank, when single vacuum source lost efficacy or vehicle during at lower long slope, the part vacuum that vacuum air storage tank stores can, separately as secondary vacuum source, provide part supply, guarantees traffic safety.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 is vacuum pressure charging valve partial enlarged drawing of the present utility model,
The flow direction of each check valve indicates with arrow in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of vacuum line structure of brake system of car, comprise and strengthen pipeline and supply pipeline, vacuum air storage tank 11, strengthen pipeline and comprise reinforced pipe 4 and vacuum pressure charging valve 7, vacuum pressure charging valve 7 has three interfaces, an interface is communicated with inter cooling pipeline 1, between this interface and inter cooling pipeline 1, be provided with a check valve A6, an interface is communicated with induction maniflod interface 21, an interface is communicated with one end of reinforced pipe 4, other one end of reinforced pipe 4 is communicated with a threeway 12, this threeway 12 is communicated with other two pipelines, the check valve B10 of leading up to is communicated to vacuum air storage tank 11, the check valve C9 of leading up to is communicated to vacuum booster interface 3, supply pipeline comprises supply pipe 5, and supply pipe 5 one end are communicated with induction maniflod interface 22, and one end is communicated to vacuum air storage tank 11 by a check valve D8 in addition.
Vacuum pressure charging valve 7 is made up of Venturi tube 72 and check valve 71, the import of check valve 71 connects reinforced pipe 4 one end, the outlet of check valve 71 connects the trunnion portion low-voltage interface of Venturi tube 72, and the import of Venturi tube 72 connects inter cooling pipeline 1, and the outlet of Venturi tube 72 connects induction maniflod interface 21.
Principle of design of the present utility model is: strengthen pipeline and supply pipeline respectively by obtaining vacuum source with being communicated with of induction maniflod; The effect that reinforcement pipeline passes through vacuum pressure charging valve is by strengthened vacuum feed vacuum booster; Provide vacuum by supply pipeline to vacuum air storage tank, this part vacuum is also stored by vacuum air storage tank; When vacuum source goes wrong while making degree of vacuum in vacuum booster very low, due to the effect of each associated one-way valve, the pipeline that vacuum air storage tank will be by being communicated to threeway to vacuum booster supply partial vacuum until vacuum exhaust.
The principle of vacuum pressure charging valve is by the swabbing action of its inner Venturi tube, reinforced pipe place to be obtained than from also high degree of vacuum of induction maniflod (vacuum source), the check valve control air flow line that it is inner, in the time that induction maniflod breaks down, air-flow can not poured in reinforced pipe.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
