Description
Technical field
The utility model relates to a kind of automobile vacuum pump.
Background technology
Vehicle-mounted vacuum pump is the power source of diesel vehicle hydraulic brake booster mostly, because gasoline-powered car
Due to engine use spark ignition type, therefore can produce higher vacuum pressure in inlet manifold, can be vacuum servo system
Dynamic system provides enough vacuum sources, and for the vehicle of diesel engine drives, owing to engine uses compression-ignited CI, this
Sample is not provided that the vacuum pressure of identical level at inlet manifold, so needing to install the vavuum pump providing vacuum source.Existing
Vavuum pump have and a lot of use belt pulley to drive, and belt pulley drives vavuum pump to bring potential wind due to higher rotating speed
There is leakage of oil in danger oil inlet passage.
Utility model content
The purpose of this utility model is to provide the higher automobile vacuum pump of a kind of simple in construction, operating efficiency.
The technical solution of the utility model is as follows: a kind of automobile belt pulley vavuum pump, including the pump housing, is provided with in the pump housing
Rotor, rotor has four blade grooves, and four blade grooves are distributed in four limits of rotor, parallel between relative two blade grooves,
Between adjacent two blade grooves vertically, it is designed with blade in four blade grooves, the pump housing is provided with bleeding point, gas outlet and drives
Moving axis, is provided with oil groove in drive shaft, be provided with bearing shell between drive shaft and the pump housing, and bearing shell is provided with bearing shell hole, bearing shell hole pair
Answering the cross-drilled hole in drive shaft, bleeding point is provided with check valve, and drive shaft is fixed with belt pulley, and belt pulley is connected to by belt
Engine, the pump housing is fixed with cover plate.
It is provided with dirt-proof boot on described check valve.
Offering four blade grooves on the rotor of vehicle-mounted vacuum pump of the present utility model, four blade grooves are distributed in rotor
Four limits, parallel between relative two blade grooves, vertical between adjacent two blade grooves, it is big that the length of such blade groove can be tried one's best
A bit, when rotor rotates, the volume that blade is inswept is bigger, in hgher efficiency；Simultaneously improve runner design, thus solved
Leakage, and the oil sealing between drive shaft and belt pulley can be cancelled, cost-saved.

Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is described in further detail:
As Figure 1-4, a kind of automobile belt pulley vavuum pump, including the pump housing 1, is provided with rotor 2, rotor 2 in the pump housing 1
On have four blade grooves 21, four blade grooves 21 are distributed in four limits of rotor, parallel between relative two blade grooves, adjacent two
Between bar blade groove vertically, it is designed with blade 3 in four blade grooves, the pump housing 1 is provided with bleeding point, gas outlet and drive shaft
5, it is provided with oil groove in drive shaft 5, between drive shaft 5 and the pump housing 1, be provided with bearing shell 9, bearing shell 9 is provided with bearing shell hole 91, bearing shell
Cross-drilled hole 52 in the respective drive of hole 91, bleeding point is provided with check valve 10, and drive shaft 5 is fixed with belt pulley 6, belt pulley 6
It is connected to engine by belt, the pump housing 1 is fixed with cover plate 4.It is provided with dirt-proof boot 14 on check valve 10.
Article four, blade groove is distributed in four limits of rotor 2, parallel between relative two blade grooves, between adjacent two blade grooves
Vertically, the length of such blade groove can try one's best big a bit, when rotor rotates, the volume that blade is inswept is bigger, and efficiency is more
High.Being provided with belt pulley 6 in the drive shaft 5 of vavuum pump, belt pulley 6 is connected to engine, driven by engine belt by belt
Wheel 6, belt pulley 6 rotor driven 2, rotor 2 carries moving vane 3 to rotate at the pump housing 1 inner chamber, drives vacuum by belt transmissioning mode
Pump, drive efficiency is high, and mechanical wear is little, improves service life and the stability of whole vavuum pump.It is provided with five on cover plate 4
Reinforcement 17, is evenly distributed on cover plate, plays the effect of reinforcing to whole vavuum pump.Arrange between drive shaft 5 and the pump housing 1
Having bearing shell 9, bearing shell 9 effectively reduces the abrasion between drive shaft 5 and the pump housing 1.It is provided with dirt-proof boot 14 on check valve 10, prevent
Dust enters in the pump housing.Such as Fig. 5, Fig. 6, oil inlet passage hole 11 connects the bearing shell hole 91 of bearing shell 9, bearing shell hole 91 respective drive
The cross-drilled hole 52 of 5, oil is flow through bearing shell hole 91 from oil inlet passage hole 11, is entered the center of drive shaft by the cross-drilled hole 52 in drive shaft 5
Oil groove, then from the center of drive shaft pass through cover plate enter die cavity, finally enter in the pump housing 1.Whole vavuum pump improves runner
Design, thus solve Leakage, and, between drive shaft 5 and belt pulley 6, original oil sealing can be cancelled, cost-saved.
