Description
Technical field
The utility model relates to vacuum pump technology field, particularly relates to a kind of vacuum line system for connecting two vacuum pump.
Background technology
There is due to battery-driven car the advantages such as energy-conserving and environment-protective, so electrically operated vehicle gets more and more, for Large Electric cars such as minibuss, the size of vacuum booster and vacuum reservoir is all larger, adopt the structure of the connecting line of single vacuum pump common at present and single vacuum pump, vacuum-assisted performance requriements cannot be met, affect traffic safety; Therefore, adopt two vacuum pump just can meet the requirement of the speed of exhaust, but, be badly in need of the vacuum line of the two vacuum pump of a set of connection of design at present, make two vacuum pump reliable operation.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is the connectivity problem of the two vacuum pump vacuum line of the Large Electric cars such as minibus, to improve traffic safety.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of vacuum line system for connecting two vacuum pump, comprise vacuum reservoir, vacuum booster and two vacuum pumps, and connecting line, the first connecting branch and the second connecting branch, two described vacuum pumps are linked together by described connecting line, one end of described first connecting branch is connected with described connecting line, its other end is connected with described vacuum reservoir, one end of described second connecting branch is connected with described first connecting branch, and its other end is connected with described vacuum booster.
Wherein, described connecting line and two described vacuum pump junctions are equipped with check valve.
Wherein, described connecting line is nylon tube.
Wherein, described first connecting branch and the tank connected one end of described vacuum are provided with quick connector, and described quick connector is connected with described vacuum reservoir by India rubber tube; One end that second connecting branch is connected with described vacuum booster is also provided with quick connector, and described quick connector is connected with described vacuum booster by India rubber tube.
(3) beneficial effect
Compared with prior art, the utility model has the following advantages:
A kind of vacuum line system for connecting two vacuum pump that the utility model provides, adopt two vacuum pump, and by connecting line, two vacuum pump is linked together, one end of first connecting branch is connected with described connecting line, its other end is connected with vacuum reservoir, one end of second connecting branch is connected with described first connecting branch, and its other end is connected with vacuum booster; System works is reliable, good airproof performance, improves the braking safety of car load.

In figure: 1: vacuum pump; 2: check valve; 3: connecting line; 4: the first connecting branches; 5: the second connecting branches; 6: quick connector; 7: India rubber tube; 8: vacuum reservoir; 9: vacuum booster.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following instance for illustration of the utility model, but is not used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, particular case the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in Figure 1, for a kind of vacuum line system for connecting two vacuum pump 1 that the utility model provides, it comprises vacuum reservoir 8, vacuum booster 9 and two vacuum pumps 1, and connecting line 3, first connecting branch 4 and the second connecting branch 5, according to the structure of two vacuum pump 1, two described vacuum pumps 1 are linked together by described connecting line 3, be interconnected, one end of described first connecting branch 4 is connected with described connecting line 3, its other end is connected with described vacuum reservoir 8, for for vacuum reservoir 8 carries out bleeding and obtain vacuum, one end of described second connecting branch 5 is connected with described first connecting branch 4, its other end is connected with described vacuum booster 9, for for described vacuum booster 9 carries out bleeding and obtain vacuum.Two vacuum pump 1 has been applied on the Large Electric cars such as minibus by the utility model, and devises corresponding vacuum line for the application of two vacuum pump 1, can meet vacuum-assisted performance requriements, improve the braking safety of car load.
Wherein, described connecting line 3 and two described vacuum pump 1 junctions are equipped with check valve 2, and when ensureing that certain vacuum pump 1 lost efficacy, another vacuum pump 1 still can normally work, and reliability is higher than the structure of single vacuum pump 1.
Particularly, described connecting line 3 can be nylon tube, and described nylon tube intensity is high, good heat resistance, can meet the application requirement of electronlmobil.
Further, one end that described first connecting branch 4 is connected with described vacuum reservoir 8 is provided with quick connector 6, and described quick connector 6 is connected with described vacuum reservoir 8 by India rubber tube 7; Quick connector 6 is connection modes of the plug and play of most convenient, especially under some tracheaes connect very inconvenient, difficult space situations, more can embody the preceence of quick connector 6, one end that second connecting branch 5 is connected with described vacuum booster 9 is also provided with quick connector 6, and described quick connector 6 is connected with described vacuum booster 9 by India rubber tube 7.
As can be seen from the above embodiments, the utility model structure design is simple, reasonable, makes two vacuum pump 1 reliable operation and pipeline system good airproof performance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
