Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1, Fig. 2 and Fig. 3; The two oil channel structures of a kind of high power engine oil pump comprise the low pressure oil circuit pump housing 1, oil pump cover 2 and the high-pressure oil passage pump housing 3; Wherein the low pressure oil circuit pump housing 1 is fixed in oil pump cover 2 both sides with the high-pressure oil passage pump housing 3; The low pressure oil circuit pump housing 1 can be fixed in oil pump cover 2 both sides by connecting bolt 16 ways of connecting with the high-pressure oil passage pump housing 3, and through locating stud 17 location.Total oil-feed port of oil pump is positioned on the low pressure oil circuit pump housing 1; Dividing plate 4 is set in the port oil-feed port is divided into the low pressure oil circuit filler opening 5 and high-pressure oil passage filler opening 6 that is not connected; Low pressure oil circuit filler opening 5 and high-pressure oil passage filler opening 6 equal semicirculars in shape; Low pressure oil circuit filler opening 5 is communicated with the low pressure oil circuit rotor chamber 7 of the low pressure oil circuit pump housing 1 and oil pump cover 2 compositions; High-pressure oil passage filler opening 6 is communicated with the high-pressure oil passage rotor chamber 8 of the high-pressure oil passage pump housing 3 and oil pump cover 2 compositions; On the low pressure oil circuit pump housing 1 and the high-pressure oil passage pump housing 3, be respectively equipped with low pressure oil circuit oil outlet 9 and high-pressure oil passage oil outlet 10, oil pump cover 2 is connected with oil pump shaft 11, and oil pump shaft 11 links respectively through driving pin 12 and is positioned at the low pressure oil circuit inner and outer rotors 13 and high-pressure oil passage inner and outer rotors 14 on the oil pump cover 2; Packing ring 15 is housed, on the oil pump shaft 11 between driving pin 12 and oil pump cover 2.This structure is passed through configuration low pressure relief valve at low pressure oil circuit oil outlet 9; Form the low pressure oil circuit with low pressure oil circuit rotor chamber 7, low pressure oil circuit filler opening 5; And high-pressure oil passage oil outlet 10 is through configuration high pressure relief valve; Form high-pressure oil passage with high-pressure oil passage rotor chamber 8, high-pressure oil passage filler opening 6, oil circuit is separate not to be connected, and the diverse location wearout parts is able to oil pressure requirement constant, sufficient lubrication in the oil pump to satisfy.
Because total oil-feed port of oil pump connects motor oil inlet passage flange plate by the end face that dividing plate 4 is separated to form high and low pressure oil circuit filler opening; Machine oil gets into high-pressure oil passage and low pressure oil circuit through this oil-feed port shunting through high and low pressure oil circuit filler opening; Wherein high-pressure oil passage filler opening 6 is communicated with high-pressure oil passage rotor chamber 8, and flow of lubricant gets into rotor chamber, surpasses the precompression (shown in Fig. 1 arrow) of high pressure relief valve when internal oil pressure; High-pressure oil passage oil outlet 10 is opened at this moment; Flow of lubricant flows out, between the component that are transported to the mutual friction of engine interior phase under the effect that stream is pressed the gap little, from the zone that the lubricant pump oil outlet far need lubricate, this zone is because the little and lubricated distance in gap between the component of phase mutual friction; Therefore not only need fuel delivery big; And need higher oil pressure, could lubricant oil be infiltrated by force the zone of the little and lubricated distance in gap, play sufficient lubrication; Low pressure oil circuit filler opening 6 is communicated with low pressure oil circuit rotor chamber 7; Another road flow of lubricant gets into rotor chamber, when internal oil pressure surpasses the precompression of low pressure relief valve (shown in Fig. 3 arrow), and oil circuit outlet end configuration low pressure relief valve; Low pressure oil circuit oil outlet 9 is opened; Flow of lubricant flows out, between the component that are transported to the mutual friction of engine interior phase under the effect that stream is pressed the gap big, from the nearer lubricated zone of needs of lubricant pump oil outlet, this zone is because the big and lubricated distance in the gap between the component of phase mutual friction is short; Therefore need not obtain high oil pressure; After preventing that oil pressure is too high, the gap position seepage of lubricant oil in can whole drainback passage is to the working life that influences motor.High and low pressure oil circuit while fuel feeding flows to different zones respectively in the oil pump, has played sufficient lubrication between each component of engine interior, reduces friction.Both can reduce power loss, and can alleviate the heating of oil again, thereby prolong the working life of motor widely.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
