Description
Technical field
The invention belongs to engine lubrication systems, are specifically designed a kind of lubricating system of dry sump.
Background technology
Engine lubrication system can be divided into wet sump and dry-oil bottom according to the difference of a large amount of stored positions of lubricating oil
Two class of shell.Conventional engine lubrication system uses wet sump, and lubricating oil pump is arranged in engine interior, directly from oil sump
Internal oil suction, and after working lubrication in the oil return to oil sump of lubricating oil gravity.It is limited by the structure of wet sump and gravity oil return
System, engine some limit operating mode, as automobile stunt unilateral side wheel land traveling, climb very steep slopes, wide-angle tilt, even overturn
Deng, engine and oil sump angle of inclination are big, participate in the machine oil reflux difficulty after lubrication, and " loss " machine oil is excessive in oil sump,
It can cause lubricating oil pump oil suction is insufficient even to inhale less than machine oil, influence the normal lubrication work of engine to damage engine.
Invention content
The purpose of the present invention is to provide a kind of lubricating system of dry sump, ensure that engine is extremely tilting operating mode
Under can normally lubricate work.
To achieve the goals above, the present invention uses following technical scheme：A kind of lubricating system of dry sump, cylinder body
Lower end is connected with dry sump, it is characterised in that：There is lubricating oil self-drying type oil sump between dry sump and grease-box
It is flow to the first oil return line of grease-box, pipeline road, main oil pump are connected between grease-box and the oil inlet of main oil pump
Oil outlet be connected to the lubricant housings of each kinematic pair, connect gas outlet on grease-box.
In above-mentioned technical proposal, lubricating oil is arranged using the oil outlet that the positive air pressure in cylinder body is arranged from dry sump bottom
Go out, entered in grease-box by the first oil return line, realizes that the lubricating oil in dry sump forces oil return to lubricating oil
In case, crankcase internal pressure is also released, and the crankcase ventilation system of engine body can be cancelled；Lubricating oil passes through simultaneously
Pipeline road reaches main oil pump from grease-box and lubricating oil is delivered to the lubrication portion of each kinematic pair by the supercharging of main oil pump
Position ensure that engine can normally lubricate work in the case where extremely tilting operating mode.
Description of the drawings
Fig. 1 is present system principle and oil circuit schematic diagram；

Specific implementation mode
As shown in the picture, a kind of lubricating system of dry sump, 10 lower end of cylinder body are connected with dry sump 20, dry type
There is lubricating oil self-drying type oil sump 20 to flow to the first oil return line 40 of grease-box 30 between oil sump 20 and grease-box 30,
Pipeline road 31 is connected between grease-box 30 and the oil inlet of main oil pump 50, the oil outlet of main oil pump 50 is connected to each movement
Secondary lubricant housings connects gas outlet on grease-box 30.
Further, it is connected with auxiliary oil pump 60 on the second oil return line 70 between booster 61 and grease-box 30, it is secondary
The oil outlet of oil pump 60 is connected to grease-box 30, and lubricating oil outflow out of cylinder body 10 reaches booster 61, by increasing along pipeline
Auxiliary oil pump 60 is reached through pipeline after the supercharging of depressor 61, last lubricating oil is pumped into grease-box 30 by the pressure of auxiliary oil pump 60
It is interior.
In said program, by first time between the oil outlet 211 and grease-box 30 of 20 bottom of dry sump setting
Oil pipe line 40 is connected.Lubricating oil because in gravity oil return to dry sump 20, using the positive air pressure in cylinder body 10 lubricating oil from
The oil outlet 211 of 20 bottom of dry sump setting is discharged, and the oil inlet of grease-box 30 is reached through the first oil return line 40, real
Lubricating oil in existing dry sump 20 is forced in oil return to grease-box 30, this process also releases pressure inside crankcase
By force, and the crankcase ventilation system of engine body can be cancelled.
The oil outlet of main oil pump 50 is connected through oil pipe with the oil inlet of machine filter module assembly 52, and machine filter module assembly 52 goes out
Hydraulic fluid port is where piping connection to each kinematic pair, further, pressure limiting valve 51 is arranged in the oil outlet pipe of main lubricating oil pump 50, adjusts
The lubricating oil pressure pumped out out of main lubricating oil pump 50 is saved, then is input in machine filter module assembly 52.
The main lubricating oil pump 50, slave oil pump 60 are impeller pump, the power rotor in main lubricating oil pump 50, slave oil pump 60
Be connected on same root pump shaft, main lubricating oil pump 50, slave oil pump 60 the pump housing be Contiuum type of structure and to be divided by isolated part
Major and minor pump chamber.Here main lubricating oil pump 50 and slave oil pump 60 are a total member, and and dry type interior mounted on dry sump 20
Oil sump 20 is integrated, and this Highgrade integration design reduces the quantity of engine component so that structure becomes more to step up
It gathers, weight more lightweight.
The top of grease-box 30 be equipped with the first and second oil return line 40,70 oil inlet one, 2 321,322, pipeline road 31
Oil outlet 311, gas outlet 312.
Preferably, grease-box 30 is the drum or cone tank of top sealing, is internally provided with strainer 33 and oil baffle 34, institute
The strainer 33 stated is cylinder or taper tubular and coaxially arranged with grease-box 30, and the oil baffle 34 is annular shape, setting
Between grease-box 30 and strainer 33.Strainer 33, oil baffle 34 and the region that 30 inner wall of grease-box encloses make entrance
Lubricating oil is drawn by oil outlet 311 again after the filtering of filter screen 33.
Further, the oil inlet one, 2 321,322 is arranged between 30 inner wall of strainer 33 and grease-box, profit
Lubricating oil is entered by oil inlet one, 2 321,322 in grease-box 30, the filtering through filter screen 33, is removed in lubricating oil
Impurity, oil outlet 311 are placed in inside strainer 33, and wherein the oil absorbing end of oil outlet 311 is placed in lubricating oil in grease-box 30 always
Liquid level below, it is ensured that lubricating oil can continuously fuel feeding.
Preferably, the outlet side of the gas outlet 312 is provided with gas and oil separating plant, it is ensured that leads to the oil gas warp of air
It is then exhausted from after crossing Oil-gas Separation.
