Summary of the invention
The object of this invention is to provide one and can reduce engine power loss, simultaneously can the engine motor oil oil supplying device of conditioner oil pressure in real time.
For achieving the above object, the invention provides following technological scheme: a kind of engine motor oil oil supplying device, comprise the oil pump arranged in the oil sump of motor, the filler opening of described oil pump is positioned at bottom oil sump, the oil outlet of described oil pump is communicated with oil duct, oil delivery is lubricated to the bent axle of motor and camshaft surface by oil duct, and described oil pump is by motoring.
Technique effect of the present invention is: oil pump adopts motor to drive replacement engine crankshaft to drive, reduce the energy loss of bent axle, and then improve the power performance of motor, in addition, another advantage motor-driven is that its rotating speed is easy to regulate, and then making the pressure of oil pump also be convenient to regulate, motor coordinates with ECU just according to the actual conditions of automobile, can regulate the engine oil pressure of motor in real time.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is oil pump mounting structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of engine motor oil oil supplying device, comprise the oil pump 11 arranged in the oil sump 10 of motor, the filler opening of described oil pump 11 is positioned at bottom oil sump 10, the oil outlet of described oil pump 11 is communicated with oil duct, oil delivery is lubricated to the bent axle of motor and camshaft surface by oil duct, and described oil pump 11 is driven by motor 12.The present invention is just based on the consideration reducing oil pump 11 frictional work, adopt a kind of motor 12 Direct driver oil pump 11, the Mechanical Driven directly or indirectly driven by bent axle is originally changed into by the electric drive of motoring, reduce the energy loss that crankshaft driving machine oil pump 11 causes, reduce the frictional work of motor.In addition, owing to have employed motor 12 Direct driver oil pump 11, the rotating speed of oil pump 11 can regulate according to the needs of motor, thus reach the object of conditioner oil pressure, make motor under each operating mode, engine oil pressure reliably controls, and reduces because oil pressure is excessive or the too small various injuries to motor caused.
Further, the start and stop of described motor 12 and rotating speed are controlled by ECU (i.e. vehicle-mounted computer); Described oil duct is connected to oil pressure sensor 18 and oil temperature sensor 19, described oil pressure sensor 18 is all connected with ECU with the signal output part of oil temperature sensor 19.At the correct position of oil duct, oil pressure sensor 18 and oil temperature sensor 19 are installed, the pressure operated by machine oil, temperature signal send to ECU, ECU is by rotating speed, engine oil pressure, the temperature signal of motor, the rotating speed of suitable adjustment motor, under making motor operate in suitable engine oil pressure.
Further, the filler opening of described oil pump 11 is connected with an oil trap 13, and described oil trap 13 is positioned at bottom oil sump 10, is provided with strainer in described oil trap 13; The oil outlet of described oil pump 11 is provided with oil filter 14, the outlet of described oil duct and this oil filter 14.Oil pump 11 filler opening arranges strainer and can reduce oil pump 11 and wear and tear, and extends oil pump 11 working life; Oil pump 11 oil outlet arranges oil filter 14, can prevent the impurity in machine oil from causing wearing and tearing to bent axle and camshaft.
Preferably, as shown in Figure 2, described oil pump 11 is arranged on oil sump 10 inwall, described motor 12 is arranged on oil sump 10 outer wall, the shell wall that the output shaft 121 of motor 12 passes oil sump 10 is connected with the main shaft of oil pump 11, is provided with seal arrangement between described output shaft 121 and the shell wall of oil sump 10.
Preferably, as shown in Figure 1, described oil duct comprises for the main oil gallery 15 to described bent axle fuel feeding, and for the branch's oil duct to described camshaft fuel feeding, described branch oil duct comprises the up oil duct 16 be communicated with main oil gallery 15 and the oil cylinder head way 17 be communicated with this up oil duct 16, described oil pressure sensor 18 is arranged on main oil gallery 15, and described oil temperature sensor 19 is arranged on the end of oil cylinder head way 17.The mounting point of oil temperature sensor 19 can be determined according to the concrete model of motor, and the oil temperature sensor 19 of the present embodiment is arranged on oil cylinder head way 17 end, compares like this and is conducive to installing.
Beneficial effect of the present invention is summarized as follows:
