Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.
Referring to Fig. 1-8, a kind of automobile engine dry sump has:
Oil sump body 1, the bottom of oil sump body 1 is provided with collector 5;
Main oil pump a and auxiliary oil pump b, is arranged in oil sump body 1, and main oil pump a and auxiliary oil pump b is arranged on same machine In oil pump drive shaft 3;
Oil returning pipe joint 8 and oil suction pipe joint 9, are arranged on oil sump body 1, and oil returning pipe joint 8 and fuel sucking pipe connect First 9 connect with external fuel tank;Oil returning pipe joint 8 goes out oil pocket 14 and connects with the auxiliary pump of auxiliary oil pump b;Oil suction pipe joint 9 and main oil The main pump oil suction chamber 16 of pump a is connected;
It is additionally provided with oil sump body 1 towards the oil duct 17 of auxiliary pump oil suction chamber 15, is connected towards the oil duct 17 of auxiliary pump oil suction chamber 15 Collector 5 and auxiliary pump oil suction chamber 15;
Hydraulic fluid port 7 is pumped out, is arranged on institute oil sump body 1, pumped out hydraulic fluid port 7 and go out oil pocket 18 with the main pump of main oil pump a and connect, Hydraulic fluid port 7 is pumped out to be connected with engine main oil gallery by pipeline.
Collector 5 is provided with collector cover plate 515, the not exclusively closing collector 5 of collector cover plate 515.
It is additionally provided with filter screen 6, the covering upper opening of collector 5 of filter screen 6.
It is additionally provided with engine oil pump cover 2 and the closing of major-minor pump closure 19 main oil pump a and auxiliary oil pump b.
Purge cock 4 is additionally provided with collector 5.
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.
