The rotor-type variable oil pump of a preferred vehicle may be modified by a person skilled in the art, and in this embodiment is a rotor-type variable oil pump.

1 is a perspective view showing a rotor type variable oil pump according to an embodiment of the present invention.

1, a rotor type variable oil pump according to an embodiment of the present invention will be described with reference to FIG. 1. The pump type compressor includes a pump housing 10 having a hydraulic chamber with oil therein and a pump housing 10 connected to the pump housing 10, And a driving unit 20 whose rotation radius is adjusted according to the hydraulic pressure of the motor.

FIG. 2 is a sectional view showing a part of the rotor type variable oil pump, and FIG. 3 is a horizontal sectional view of FIG. 2. FIG.

Referring to FIGS. 2 and 3, a rotor type variable oil pump according to an embodiment of the present invention will be described. In the pump housing 10, a hydraulic chamber having oil is formed. The pump housing 10 is formed with a connection hole to which the driving unit 20 is connected. The pump housing 10 may be formed with an annular portion R in which the oil is held so as to reduce the frictional heat of the driving portion 20 in the connection hole T. [ The pump housing 10 discharges the hydraulic pressure by a conventional pumping means using an oil pump, and a description thereof will be omitted. The pump housing 10 may include a supply port 13 for supplying oil to the annular portion R. [

And a tensioner (7) for generating a predetermined tension on a belt (B) that transmits the rotational force of the crankshaft (5) to the driving unit (20) Tension can be adjusted by the tensioner 7 and the belt B according to the turning radius of the belt 20.

The supply port 13 is formed to protrude out of the pump housing 10 so that oil can be injected from the outside of the pump housing 10. The pump housing 10 may be formed with an oil passage T connected from the supply port 13 to the annular portion R. [

The oil passage T extends from the supply port 13 in the pump housing 10 to the annular portion R so that the oil injected from the supply port 13 is transferred to the annular portion R.

The driving unit 20 is connected to the main gallery 1 through the pump housing 10. The driving unit 20 may include a stroke 30 connected to the inside of the pump housing 10 and a variable pulley 40 connected to move to the hydraulic pressure through the stroke 30. The driving unit 20 can change the outer diameter of the variable pulley 40 to adjust the rotation ratio.

More specifically, the stroke 30 of the driving unit 20 is provided with a stroke bar 32, one side of which is connected to the pump housing 10. The stroke 30 is formed with a moving part 34 separated from the other side about the axis of the stroke 30 so that the variable pulleys 40 are connected to each other. That is, the stroke bar 32 is inserted into the pump housing 10 so as to be rotatable about the axis of the stroke bar 32, and the moving part 34 is formed on the other side protruding outward of the pump housing 10.

The inside of the stroke bar 32 is penetrated to form a penetration portion 32a so as to discharge the hydraulic pressure inside the pump housing 10. [ The outer peripheral surface of the stroke bar 32 is surrounded by the annular portion R so that the frictional heat generated by the rotation of the stroke 30 by the oil supplied to the annular portion R can be reduced.

The variable pulley 40 can be adjusted in its turning radius from the pump housing 10 by hydraulic pressure. The variable pulley 40 is regulated in the turning radius by the hydraulic pressure introduced through the penetration portion 32a of the stroke 30. [ A plurality of variable pulleys (40) are provided in the stroke (30). That is, a plurality of variable pulleys 40 are provided and inserted at both ends of the moving portion 34. [ The variable pulley 40 is inserted into the moving part 34 in a linear motion, and is moved by hydraulic pressure.

More specifically, the variable pulley 40 includes a plate 44 which moves in the moving part 34, a connecting part 46 which extends from the center of the plate 44, And a flange 42 formed in a hemispherical shape.

The flange 42 may have a hemispherical shape so as to form a spherical shape when the driving unit 40 rotates. A belt B is connected to the flange 42 so as to be connected to the crankshaft 5. A moving part 34 and a plate 44 which is moved by the moving part 34 are formed from a connecting part 46 extending from the flange 42. The plate 44 is formed so as to have the same inner diameter as the moving part 34, thereby preventing the hydraulic pressure from flowing out and allowing the variable pulley 40 to linearly move by the hydraulic pressure.

6 is a view showing another embodiment of the driving unit.

6, the driving unit 20 may include rack pinion units 148 and 248 for uniformly moving the variable pulleys 140 and 240 provided in a plurality.

The variable pulleys 140 and 240 are connected to the rack pinion portions 148 and 248 on the plates 144 and 244 so as to uniformly move the plurality of variable pulleys 140 and 240. The driving unit 20 may include rack pinion units 148 and 248 that uniformly move the plurality of variable pulleys 140 and 240. On the other hand, the rack pinion portions 148 and 248 can connect the plurality of variable pulleys 140 and 240 to each other.

The rack pinion portions 148 and 248 extend to the plates 144 and 244 and form racks 148a and 248a and pinions 148b and 248b are provided between the racks 148a and 248a to rotate the pinions 148b and 248b The racks 148a and 248a are moved by the pulleys 140 and 240 to move the variable pulleys 140 and 240 constantly.

The operation of the rotor type variable oil pump according to the preferred embodiment of the present invention will be described below.

4 and 5 are views showing a vertical section (a) and an operation (b) of the driving section.

4 and 5, the tension of the belt B, which changes in accordance with the turning radius of the variable pulley 40, can be maintained constant by the tensioner 7 have. That is, when the turning radius of the variable pulley 40 becomes larger and the tension of the belt 5 becomes higher due to the diameter of the crankshaft 5, the tensioner 7 adjusts the tensioner 7 so that the belt B Lowering the pressure reduces the generation of tension. On the contrary, when the turning radius of the variable pulley 40 is small, the tensioner 7 presses the belt B with the tensioner 7 so that the tension is made small so that the tension can be kept constant.

Therefore, when the turning radius of the variable pulley 40 is reduced, the rotation ratio becomes larger as compared with the engine driving portion, and the acceleration effect is generated, and the oil pump discharge amount increases due to the increase of the rotation ratio. When the turning radius of the variable pulley 40 is increased, the rotation ratio of the variable pulley 40 becomes smaller than that of the engine drive portion, so that the deceleration effect is generated.

Accordingly, according to the rotor type variable oil pump of the present invention, the durability of the rotor is improved by adjusting the discharge amount of the pump by adjusting the rotation ratio of the pulley, the development is easy due to the small disturbance factor such as the pressure inside the slide, So that the fuel consumption is reduced.

The rotor type variable oil pump according to the embodiment is not limited to the configuration and the method of the embodiments described above, but the embodiments may be modified so that all or some of the embodiments are selectively As shown in FIG.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention.
