Description
Technical field
The utility model is related to a kind of oil seal type electric vacuum pumps, belong to brake system of car control field.
Background technology
With popularizing for new-energy automobile, motor wants power resources instead of petrol engine as automobile primary, it is desirable that
Relying on the associated vehicle technology of engine will also be changed, and be provided very for vacuum booster by motor intake manifold originally
The technology of empty condition needs to realize using electric vacuum pump.
Modern fuel vehicle mostly uses greatly auxiliary power-assisted mode of the vacuum booster as braking system.Vacuum booster passes through
Check valve is communicated with motor intake manifold, when the engine runs, generates negative pressure, and then formed and pressed at booster diaphragm both ends
Force difference, to have the function that mitigate brake pedal operation power, the size of vacuum degree directly affects braking effect.For electronic vapour
For vehicle, engine is replaced by motor, the vacuum source not used for booster cannot generate the effect of power-assisted, at this time
Vacuum booster necessary power-assisted cannot be provided for driver ensure.Electric vacuum pump passes through the detection of sensor and logic
Judgement can be well solved this problem.The use of electric vacuum pump, it is ensured that the vacuum degree in booster maintains centainly
Level, for running car provide good brake efficiency, ensure driving safety.
Existing electric vacuum pump mainly has vane pump, piston pump and diaphragm pump, and piston pump is the disadvantage is that piston and casing wall
It rubs larger, efficiency and endurance quality are poor；Diaphragm pump is the disadvantage is that higher to diaphragm material performance requirement.Vane pump is answered at present
With relatively broad, such as patent publication No. CN101603536B, publication date on October 5th, 2011, the title that utility model is created
For electric vacuum pump for automobile, shortcoming is that requirement provides higher rotating speed to reach preferable vacuum degree, is easy in this way
Keep motor radiating condition insufficient, reduces functional reliability, in addition easy to produce larger noise.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art, provide one kind be skillfully constructed, can
The oil seal type electric vacuum pump strong by property, heat dissipation is good and efficient.
In order to solve the above technical problems, the utility model provides a kind of oil seal type electric vacuum pump, it is characterised in that：Packet
Include double end motor, gear oil pump, oil sealing vacuum pump, vacuum booster and fuel tank；Double end motor one end and oil seal type
The rotor dynamic of vacuum pump connects, the other end and gear oil pump be connected by power；The oil inlet pipe of the gear oil pump and going out for fuel tank
Hydraulic fluid port connects；The flowline of gear oil pump is connect with oil sealing vacuum pump fuel feed hole；The vacuum booster and oil sealing vacuum
Pump is connected by vacuum tube；The oil gas vent of the oil sealing vacuum pump is connected with the oil return hole of fuel tank by oil pipe.
The technical solution that the utility model further limits is：Check valve is installed at the oil return hole of the fuel tank.
Further, fuel tank oil outlet source is equipped with oil strainer.
Further, top is equipped with the partition board that stomata is arranged in the fuel tank.
Further, oil return valve is installed on the partition board.
Further, gs-oil separator is installed above the partition board.
The utility model has the beneficial effects that：Compared with prior art, the utility model structure design is relatively reliable, performance
It is more stable；The utility model can realize better vacuumizing effect and more efficient under motor same rotational speed；In addition, oil sealing
The heat dissipating state of formula vacuum pump is good, and pumping fluid can also reduce the abrasion of oil sealing vacuum pump inner body.

Specific implementation mode
Embodiment 1
A kind of oil seal type electric vacuum pump provided in this embodiment, as shown in Figs. 1-3：Including gear oil pump 1, gear oil pump
Flowline 2, double end motor 3, oil sealing vacuum pump 4, vacuum tube 5, vacuum booster 6, oil return pipe 7, fuel tank 8, gear oil pump into
Oil pipe 9, pumping fluid 10, oil strainer 11, oil outlet 12, oil return hole 13, check valve 14, partition board 15, oil return valve 16, oil gas point
From device 17, oil seal type vacuum pump oil gas outlet 18, oil sealing vacuum pumps fuel feed hole 19, oil sealing vacuum pumping gas port 20.
3 one end of double end motor directly drives the rotor rotation of oil sealing vacuum pump 7, the other end that gear oil pump 1 is driven to carry out
Oil pumping, gear oil pump oil inlet pipe 9 are connect with oil outlet 12, and gear oil pump flowline 2 is connect with oil sealing vacuum pump fuel feed hole 19,
Vacuum booster 6 is connect with oil sealing vacuum pump 4 by vacuum tube 5, and oil seal type vacuum pump oil gas outlet 18 and oil return hole 13 are logical
Cross the connection of oil return pipe 7.
Oil gas in oil sealing vacuum pump 4 is entered by oil return pipe 7 in fuel tank 8, and check valve 14 is mounted on oil return hole 13
In, prevent pumping fluid from being flow backwards from oil return hole.
Pumping fluid 10 by after oil strainer 11 enter gear oil pump oil inlet pipe 9, pumping fluid by oil strainer into
Row filtering after enter gear oil pump oil inlet pipe, oil sealing vacuum pump 4 enter the gas in fuel tank 8 by after partition board 15 by oil gas
Separator 17 is handled, and the pumping fluid 10 carried in gas returns to fuel tank shell after the processing of gs-oil separator 17 by oil return valve 16
Below body.
While oil sealing vacuum 4 pairs of vacuum boosters 6 of pump vacuumize, gear oil pump 1 notes oil sealing vacuum pump 4
On the one hand oil is the heat taken away oil sealing vacuum pump 4 and generated, be on the other hand to form oil film in oil sealing vacuum pump 4, from
And it can realize better vacuumizing effect.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
