Background technology
Oil sump is located at the lower half of crankcase, is also called lower crankcase, and the major function of oil sump is to store machine oil simultaneously
Closed crankcase, prevents impurity from entering, and collects and store the machine oil by being flowed back to after each friction lubricating of engine, oil sump surface
Certain heat sinking function is required, oil ageing is prevented.Current oil sump is generally stamped to form using sheet metal, its shape
It is decided by the general layout of engine and the capacity of machine oil.Machine oil in order to allow inside oil sump preferably radiates, some
Engine employs the oil sump that aluminium alloy casts material, and bottom is also cast with corresponding fin.Wet sump in order to
Lubricating oil pump can normally be drawn onto machine oil when ensureing engine tilts, and oil sump bottom is typically made deeper;In addition, oil sump inside is also
Oil baffle is provided with, pasta fluctuates excessive when preventing running car;Bleeder plug is designed as with magnetic texure, in absorbing and collecting machine oil simultaneously
Metal fillings, with reduce engine part abrasion.
Now, what most of automobiles were assembled is all wet sump, and wet sump has one than larger problem,
Be exactly that, when vehicle is under limit transport condition, for example the excessively curved or limit gets over Yezhong at a high speed, in-engine lubricating oil due to
Centrifugal force or gravity and be gathered in a part of engine sump tank, cause engine cannot oil suction, insufficient lubrication and make
Engine damage.Why wet sump is named as, is the bent axle rotation bag of engine due to starting in wide-angle tilt
Winding thread can be immersed in machine oil, and due to running at high speed for bent axle, the mist of oil that bent axle runs at high speed all with engine interior every time is produced
Friction, mist of oil plays lubrication to cylinder wall.Liquid level so to lubricating oil in oil sump just has certain wanting
Ask, oil sump engine oil level is rationally appropriate with the distance of bent axle envelope, and the distance can not be too small, lubricating oil liquid level meeting too high
Cause bent axle to stir oil when rotating so that the rotational resistance increase of bent axle, engine performance decline is ultimately resulted in, while lubricating oil
It is easily accessible in cylinder combustion room, the problems such as cause engine burn oil, sooting of the spark plug.
The content of the invention

Integrated limited valve on engine oil pump cover 2.
The discharge capacity that turns of auxiliary oil pump b turns discharge capacity not less than main oil pump a.
O-ring 20 is provided between oil returning pipe joint 8 and oil suction pipe joint 9 and oil sump body 1 to seal.
The advantage of dry sump technology is embodied in four aspects:(1) dry sump improves engine power:Due to dry
Hardly there is machine oil in the food tray of formula oil sump, therefore do not exist during engine crankshaft operating and stir oily resistance;In addition plural parallel stage
Scavenge oil pump increased the vacuum in crankcase, and resistance reduces when making bent axle, piston movement, and can make the power of engine has one
Fixed lifting.(2) dry sump increases engine lubrication performance:Because the machine oil entered in engine main oil gallery comes from machine oil
Case, rather than directly from oil sump, therefore playing the engine oil quality of lubrication more preferably, pressure is higher, and flow is more stable, increased
To the lubricant effect of engine, this advantage particularly manifests in durable match.(3) dry sump improves vehicle driving stability
Property:Because the food tray of dry sump is very low, the height of engine is decreased, and then reduces the center of gravity of vehicle.Have
Food tray is designed to low early and high after wedge shape, engine is leaned forward, and can also further lower the center of gravity.The reduction of center of gravity can improve car
The stability and handling of traveling, for needing match occasion excessively curved at a high speed especially pronounced.(4) dry sump can be fitted
Answer harsh travel conditions:In due to the additional sump of dry sump System Computer oil measure presence, and allow to ask interior returning in short-term
Oil pump dallies, and this feature causes that it can apply to military vehicle or other special vehicles.Dry sump technology is derived from racing car
Motion, it can improve the lubricating ability and handling of engine by using a set of improved lubricating system, and improve match
The power of car.Simultaneously as its outstanding performance and the adaptability to various travel conditions, can apply to it
Military vehicle or other special vehicles.
The frictional work of engine can be effectively reduced, effective engine power is improved, the center of gravity of engine is effectively reduced, carried
Vehicle handling stability high, is widely used in a kind of dry sump of sport car, aircraft.Structure of the present invention mainly includes:Oil sump,
Collector cover plate 515, filter screen 6, oil returning pipe joint 8, oil suction pipe joint 9, main oil pump a and auxiliary oil pump b composition.Wherein lubricating oil pump master
Oil pump a includes main pump outer rotor 10, main pump internal rotor 11;Lubricating oil pump auxiliary pump includes the auxiliary pump internal rotor 13 of auxiliary pump outer rotor 12.It is main
Connected by major-minor pump closure 19 between oil pump a and auxiliary oil pump b.A lubricating oil pump is shared between main oil pump a and auxiliary oil pump b to drive
Axle 3.
Using single external fuel reserve tank, wet sump bent axle is reduced with rubbing that the lubricating oil of splashing clashes into and produces
Wipe, improve the effective power of engine.
The oil return of engine, after filter screen 6 filters larger impurity, enters by towards the oil duct 17 of auxiliary pump oil suction chamber 15
Auxiliary pump, pressure lubrication oil goes out oil pocket 14 by auxiliary pump, towards external tank drainback pipe joint 8.
The external fuel tank of oil suction pipe joint 9, main pump oil suction chamber 16 is entered by grease pump, is sent to main pump and is gone out oil pocket 18, pressure
Lubricating oil enters engine main oil gallery by pumping out hydraulic fluid port 7.Because the machine oil of engine interior can in time be transported to fuel reserve tank,
The friction that bent axle is produced with engine interior oil gas is reduced, the effective power of engine is lifted.
Lubricating oil pump is integrated on oil sump by main oil pump a and auxiliary oil pump b, because the ratio that oil sump does is shallower, is effectively reduced
The center of gravity of engine, can be improving the control stability of vehicle.
Lubricating oil pump is integrated on oil sump by main oil pump a and auxiliary oil pump b.Pressure limiting valve is integrated on engine oil pump cover 2.In order to
Ensure that the machine oil in oil sump returns to oil sump in time, the discharge capacity that turns of auxiliary pump turns discharge capacity not less than main pump.
Oil trap 5 is integrated with, the collector 5 is made up of collector cover plate 515, filter screen 6.Lubricating oil pump is by main oil pump a
And auxiliary oil pump b compositions, integrated with oil sump, the Integration Design of height so that cost is minimized.
In order to ensure the excellent sealing of oil returning pipe joint 8 and oil suction pipe joint 9, using O-ring 20, by radial seal come
Ensure.
After using above-mentioned structure,
(1) designed using dry sump, using single fuel reserve tank, reduce wet sump bent axle with the profit splashed
The friction that lubricating oil clashes into and produces, improves the effective power of engine.
(2) ratio that oil sump does is shallower, effectively reduces the center of gravity of engine, can improve the operational stability of vehicle.
(3) be integrated with the parts such as oil trap 5, lubricating oil pump, height it is integrated, cost is minimized.
(4) even if the machine oil of engine interior can be reduced bent axle and produced with engine interior oil gas to be transported to fuel reserve tank
Friction, lifted engine effective power.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Limitation, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and design of the invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
