As in figure 2 it is shown, offer oil-in 1, oil-feed tract 2, oil suction tract 3, fuel-displaced on oil pump case 13
Tract 5 and function tract 8；Be provided with on function tract 8 for make pressure oil lubrication variator one axle and
The oil leab 9 of two axles.Oil-in 1 is positioned at the lowest part of oil pump case 13.As shown in Figure 4, clutch
Position corresponding with oil-in 1 on device housing 10 offers for making transmission oil enter oil-feed
The through hole of mouth 1, is also equipped with filter 23 at oil-in 1.Between fuel-displaced tract 5 and function tract 8
It is provided with the dividing wall 7 for being separated by two oil pockets.As it is shown in figure 5, offer use on dividing wall 7
In the intercommunicating pore 6 that fuel-displaced tract 5 is connected with function tract 8；It is further opened with leading to oil on function tract 8
Passage outside pump case 13, and be provided with on passage for realizing in forced feed lubrication and forcing between cooling
The oil switched over blocks up or oil connection.Operation cover plate 12, oil pump casing are installed on clutch housing 10
The first hole path 15 and the second hole path 16 being connected with function tract 8 is offered on body 13, first
Hole path 15 faces intercommunicating pore 6；And operation cover plate 12 is just to the first hole path 15 and the second hole path
16.As shown in Figure 5 and Figure 6, the first hole path 15 and the second hole path 16 are mounted on screw plug 14
Or it is respectively mounted long oil connection 17 and short oil pipe joint on the first hole path 15 and the second hole path 16
18.Long oil connection 17 and short oil pipe joint 18 are hollow structure, and the shaft shoulder of long oil connection 17
Being pressed on dividing wall 7 by sealing member 24, the most fuel-displaced tract 5 and function tract 8 are separated.
The principle of the present invention and work process:
As it is shown in figure 1, clutch housing 10 is arranged on the front end of case of transmission 11, at bell housing
Equipped with an operation cover plate 12 on body 10, dismounting lower 12 is it is seen that integral type oil pump 25, integral type
Oil pump 25 securing member is arranged on clutch housing 10, as it is shown in figure 5, operation cover plate 12 faces oil
Two hole paths of pump assembly.
As it is shown on figure 3, integral type oil pump 25 by oil pump case 13, the outer rotor 19 of internal messing, interior turn
Son 20, internal rotor pin 21 and oil pump cover 22 form.As in figure 2 it is shown, be designed with on oil pump case 13 into
Hydraulic fluid port 1, oil-feed tract 2, oil suction tract 3, fuel-displaced tract 5, and function tract 8 etc..Fuel-displaced tract 5
And between function tract 8, have dividing wall 7 to be separated by 2 oil pockets, but have again on dividing wall 7
Intercommunicating pore 6 can be by two oil pocket connections.Have first hole path the 15, second hole on oil pump case 13 to lead to
Road 16 connects with function tract 8, and the first hole path 15 faces intercommunicating pore 6.
As shown in Figure 4, oil-in 1 is arranged on extreme lower position, correspondence position processing on clutch housing 10
One through hole, transmission oil can arrive oil-in 1, (as preferably, can be at oil-in 1
Increase filter 23).During operation of oil pump, lubricating oil can from oil-in 1 to oil-feed tract 2 again through oil suction
Tract 3 enters integral type oil pump 25, pressurized after discharge from fuel-displaced tract 5.It is full of by intercommunicating pore 6
Whole function tract 8.Having oil leab 9 on function tract, pressure oil can lubricate change from oil leab 9
One axle of speed device and two axles, all can arrange lubricant passage way in all positions of function tract 8, only need to be at this
A hole, lubricating place 4 at as depicted two is processed on the clutch housing that position is corresponding.
As preferably, if variator needs first to carry out forcing cooling to carry out forced feed lubrication again, only need to pull down
Cover plate 12 on clutch housing, then pull down two spiral shells on the first hole path 15 and the second hole path 16
Stifled 14, in first hole path the 15, second hole path 16, it is respectively mounted long oil connection 17 and short oil
Pipe joint 18, oil connection is hollow structure, and sealing member 24 is compressed by the shaft shoulder of long oil connection 17
On dividing wall 7, the most fuel-displaced tract 5 and function tract 8 are separated, as shown in Figure 6.From
After the pressure oil of oil pump enters fuel-displaced tract, flowed out outside variator by long oil connection 17, and carry out heat
Exchange, the pressure oil after cooling returns to function oil pocket 8 from oil connection 18, and by communicating with this oil pocket
Forced feed lubrication passage is to carrying out forced feed lubrication in variator.
Above content is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this,
Every technological thought proposed according to the present invention, any change done on the basis of technical scheme, all fall
Within entering the protection domain of claims of the present invention.
