Detailed description of the invention
For making patent of the present invention solve the technical problem that, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
Explicitly indicating that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or it becomes
Change and such as " comprising " or " including " etc. will be understood to comprise stated element or ingredient, and do not get rid of other yuan
Part or other ingredients.
As shown in Figure 1 (arrow represents fluid and flows to), move according to the distributed mixing of patent detailed description of the invention of the present invention
The concrete structure of power variator dry sump system includes: dry sump 11, external oil drain pump 12, duplex pump drive motor
13, fuel reserve tank 14 and oil scavenge pump 15.Wherein, dry sump 11 is arranged in the bottom of hybrid gearbox；Fuel reserve tank 14 is pacified
It is contained in variator 15 outside；External oil drain pump 12 and oil scavenge pump 15 by driving motor 13 to drive are arranged on hybrid gearbox
16 is outside, and is connected with dry sump 11 and fuel reserve tank 14 respectively by fluid pipeline, will be stored in the oil in fuel reserve tank 14
Liquid pumps to hybrid gearbox to be needed shift clutch oil pocket and needs lubrication and the position of cooling, lubricates and cooling completes
After, due to action of gravity, fluid returns to be positioned at the dry sump 11 of engine bottom again, then by external duplicate gear
The fluid that dry sump 11 is collected is pumped to fuel reserve tank 14 by the oil drain pump 12 of pump, completes whole circulation.Move in original mixing
On the basis of power variator wet sump system, set up external by oil drain pump 12, oil scavenge pump 15 and fuel reserve tank 14 form double
Connection gear pump, fuel reserve tank 14 and associated pipe, and wet sump is replaced by dry sump 11, hybrid gearbox becomes
For distributed dry sump system.Only increasing through simple and reduce relevant parts, variator can be at dry-oil
Drain pan and wet sump directly switch, and add the suitability of hybrid gearbox.
Wherein, as shown in Figure 3 and Figure 4, dry sump 11 includes: dry sump body 21, and is opened in dry type
Oil trap 22 bottom oil sump body 21 and the external lubricating oil pump interface 23 being opened in this this body side surface of dry sump, oil-collecting
The cover plate 24 of band sieve aperture 31 it is covered with on groove 22.Distributed dry sump 11 has an oil trap 22, is used for collecting clutch
Work fluid etc., after lubricating or having cooled down, before and after returning to bottom hybrid gearbox again due to the effect of gravity
The fluid of side；The bottom of oil trap 22 is further opened with drain tap.External oil drain pump 12 interface is two, the inner and oil trap 22 phase
Even, outer end is for being connected with fuel reserve tank 14 oil-in by fluid pipeline, with by oil in the oil trap 22 of dry sump 11
Liquid pumps to fuel reserve tank 14.The two ends of the oil scavenge pump 15 of duplex gear pump oil main with fuel reserve tank 14 and hybrid gearbox respectively
Road is connected by pipeline, forms two-stage lubricating oil pump and pumps structure.Work fluid within variator needs the sieve through cover plate 24
Hole 31 could enter oil trap 22 and circulate, and sieve aperture 31 can eliminate the bubble in fluid, to increase its cycle efficieny, it is ensured that fluid
Viscosity.
As it is shown in figure 5, external duplex gear pump is made up of oil drain pump 12 and oil scavenge pump 15, and by gear spline 41 by driving
Galvanic electricity machine 13 drives, and carries out oil extraction and two cycle of operation of oil suction for system.Wherein oil drain pump oil-in 42 passes through fluid pressure line
Being connected with dry sump lubricating oil pump interface 23, fluid is transported to fuel reserve tank 14 by oil drain pump oil-out.Oil scavenge pump oil-in
43 with fuel reserve tank 14 oil-out, fluid is pumped to positions such as hybrid gearbox main control oil circuit and lubricant passage waies.And,
The flow of oil drain pump 12 is 2 times or more than 2 times of oil scavenge pump 13.
To sum up, this hybrid gearbox dry sump system is pacified by wet sump system is improved to fuel reserve tank
It is contained in variator outside and the dry sump system of external duplex gear pump, thus reduces the entirety of hybrid gearbox
Highly, improve the hybrid gearbox suitability at small space；Avoid the vehicle travelled under bad working environments simultaneously
Owing to variator tilts to cause fluid to be emptied, make gearshift hydraulic system oil starvation cause gearshift to lose efficacy, affect road holding, special
It it not the driving performance on various precipitous road surface.It addition, dry sump owing to fluid have passed through more pipeline and fuel reserve tank,
During this, fluid can be adequately cooled, and reduces oil liquid temperature, it is ensured that oil viscosity, improves the life-span of fluid.
The aforementioned description to the specific illustrative embodiment of patent of the present invention illustrates that and the purpose of illustration.These
Describe and be not wishing to be defined to patent of the present invention disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
A lot of changes and change.The purpose selected exemplary embodiment and describe is to explain the certain principles of patent of the present invention
And reality application, so that those skilled in the art is capable of and utilizes the various different example of patent of the present invention
