Description
Technical field
The present invention relates to the parts of automobile, more specifically to a kind of automobile brake vacuum lamp.
Background technology
Be equipped with the driving engine of air inlet turbine pressure charging system, in induction maniflod, air pressure is higher, cannot meet the vacuum level requirement of vacuum booster, and needing to increase vacuum pump provides degree of vacuum to vacuum booster.Be used alone vacuum pump, the vacuum level requirements of vacuum booster can be met, but the degree of vacuum of driving engine cannot be utilized effectively, particularly be used alone electronic vacuum pump and degree of vacuum is provided, electronic vacuum pump working strength high and consume the energy.
Summary of the invention
The object of this invention is to provide a kind of automobile brake vacuum lamp, it can under the prerequisite of vacuum level requirement meeting vacuum booster, and effect utilizes the degree of vacuum of engine intake manifold, reduces the working strength of vacuum pump.
Automobile brake vacuum lamp of the present invention, comprise the first flexible pipe, the second flexible pipe, the 3rd flexible pipe, the 4th flexible pipe, five weaknesses pipe, the first T-pipe joint and the second T-pipe joint, one end of described first flexible pipe is the vacuum lamp interface for connecting vacuum pressure sensor, and its other end is connected with one end of the first T-pipe joint; One end of described second flexible pipe is provided with the joint for joint brake vacuum booster, and its other end is connected with the other end of the first T-pipe joint; One end that first T-pipe joint is left is connected with one end of the 3rd flexible pipe, the other end of the 3rd flexible pipe is connected with one end of the second T-pipe joint, all the other two ends of second T-pipe joint respectively with the 4th, one end of five weaknesses pipe is connected, the other end of the 4th flexible pipe is the induction maniflod interface for connecting engine induction maniflod, in the 4th flexible pipe, be provided with the first check valve; The other end of five weaknesses pipe is provided with the vacuum pump interface for connecting vacuum pump, is provided with the second check valve in five weaknesses pipe.
Automobile brake vacuum lamp of the present invention, owing to having said structure, automobile brake vacuum lamp is connected with vacuum booster, vacuum pump, engine intake manifold and vacuum sensor respectively, on vacuum lamp, vacuum booster interface and vacuum sensor are path, vacuum sensor can degree of vacuum in brake monitoring vacuum booster, and the work controlling electronic vacuum pump provides degree of vacuum for brake vacuum pump; In engine intake manifold, degree of vacuum as a supplement, carries out providing degree of vacuum to vacuum booster.The present invention effectively make use of the degree of vacuum of engine intake manifold, thus reduces the working strength of vacuum pump.In addition, when electronic vacuum pump lost efficacy, driving engine can provide partial vacuum, improve safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is fundamental diagram of the present invention.
Detailed description of the invention
In order to explain technical scheme of the present invention further, below in conjunction with accompanying drawing, the present invention will be described in detail.
Described in Fig. 1, this automobile brake vacuum lamp, comprise the first flexible pipe 2, second flexible pipe 5, the 3rd flexible pipe 8, the 4th flexible pipe 11, five weaknesses pipe 13, first T-pipe joint 6 and the second T-pipe joint 9, one end of described first flexible pipe 2 is vacuum lamp interface 4, reliably be connected with vacuum pressure sensor with clip 1 by vacuum lamp interface 4, its other end is connected with one end of the first T-pipe joint 6, is also provided with clip 1 in junction.One end of described second flexible pipe 5 is provided with the joint 3 for joint brake vacuum booster, its other end is connected with the other end of the first T-pipe joint 6, one end that first T-pipe joint 6 is left is connected with one end of the 3rd flexible pipe 8, the other end of the 3rd flexible pipe 8 is connected with one end of the second T-pipe joint 9, all the other two ends of second T-pipe joint 9 respectively with the 4th, one end of five weaknesses pipe 11,13 is connected, the other end of the 4th flexible pipe 11 is the induction maniflod interface 7 for connecting engine induction maniflod, in the 4th flexible pipe 11, be provided with the first check valve 10.The junction of five weaknesses pipe 13 and the second T-pipe joint 9 is provided with clip 1, and the other end of five weaknesses pipe is vacuum pump interface 14, and vacuum pump interface 14 is reliably connected with vacuum pump with clip 1, is provided with the second check valve 12 in five weaknesses pipe 13.
Described in Fig. 2, principle of work of the present invention is: degree of vacuum pressure sensor is by the degree of vacuum in brake monitoring vacuum booster, the work controlling electronic vacuum pump provides degree of vacuum for brake vacuum pump, in engine intake manifold, degree of vacuum as a supplement, carry out providing degree of vacuum to vacuum booster, specific works mode is:
When automobile is starting state, when vacuum pressure sensor monitors degree of vacuum p < α in vacuum booster (α is degree of vacuum in engine intake manifold), ECU controls electronic vacuum pump work, open near electronic vacuum pump end with near engine intake manifold end check valve, electronic vacuum pump and engine intake manifold are simultaneously for vacuum booster provides degree of vacuum.In this process, in engine intake manifold, degree of vacuum is utilized effectively, and decreases work-hours and the working strength of electronic vacuum pump.
When vacuum pressure sensor to monitor in vacuum booster degree of vacuum for during β > p > α time (degree of vacuum of β required for vacuum booster), near electronic vacuum pump end one-way valve opens, ECU controls electronic vacuum pump and works on; Near engine intake manifold end closed check valve, prevent vacuum leak to engine intake manifold.
When to monitor degree of vacuum in vacuum booster be p > β > α to vacuum pressure sensor, near electronic vacuum pump end with near engine intake manifold end closed check valve, ECU controls electronic vacuum pump and quits work.
When electronic vacuum pump et out of order, degree of vacuum p < α in vacuum booster, near the one-way valve opens of engine intake manifold side, engine intake manifold provides degree of vacuum for vacuum booster, vacuum booster can not be entirely ineffective, increases vehicle safety.
