Device, it is differed only in embodiment one, wherein, electrodynamic pump 6 is also provided at coupling machine
The outside of structure, and the mechanical pump 18 of the present embodiment is connected by first gear pair with jackshaft 11,
Specifically, first gear pair include intermeshing mechanical pump driving gear 15 and mechanical pump from
Moving gear 16, one end that jackshaft 11 is connected with second gear 10 is to the direction of mechanical pump 18
Extend a distance into and be connected with mechanical pump driven gear 16, and mechanical pump driving gear 15 is set
In on the input shaft 17 of mechanical pump, the operating band by motor 13 thus can also be realized
The function that dynamic mechanical pump 18 is operated.The other structures of the present embodiment are identical with embodiment one.
The present invention also provides a kind of control of hybrid vehicle coupling mechanism cooling and lubricating device
Method, it is used to switch over the mode of operation of cooling and lubricating device, wherein, cooling and lubricating
Device includes two kinds of mode of operations.
Two kinds of mode of operation contrast tables of the cooling and lubricating device of table one
The control method of the present embodiment comprises the following steps：
S1, the work order for receiving the coupling mechanism that coupling mechanism controller is sent；
S2, when coupling mechanism be in electric-only mode when, electrodynamic pump 6 does not work, pass through coupling
Mechanics controller controls clutch separation, and engine 1 and generator 9 are stopped, driving electricity
The driving mechanical pump 18 of machine 13 operates to carry out cooling and lubricating to motor 13；
S3, when coupling mechanism be in increase journey pattern when, pass through coupling mechanism controller control clutch
Device is separated, and electrodynamic pump operating carries out cooling and lubricating to generator, while motor driving machinery
Pump operating is with to motor progress cooling and lubricating；
S4, when coupling mechanism be in hybrid mode when, controlled by coupling mechanism controller
Clutch is engaged, and electrodynamic pump 6 is operated carries out cooling and lubricating to generator 9 and clutch 7, together
When motor 13 driving mechanical pump 18 operate with to motor carry out cooling and lubricating.
Because hydraulic module 38 is controlled by coupling mechanism controller, and second opens
Close the 34, the 3rd and switch the 35, first cooling oil passage, the second cooling oil passage 41 and the 6th pipe
Road 29 is integrated in hydraulic module 38, therefore, in the control method of the present embodiment, and second
The switch 35 of switch 34 and the 3rd is controlled by coupling mechanism controller.
Specifically, as shown in above-mentioned table one, below it should be noted that Second Threshold is more than the
One threshold value, when automobile battery power is more than Second Threshold, coupling mechanism controller control the 3rd
Switch 35 is opened so that the 5th pipeline 28 is disconnected, and clutch 7 is separated, now coupling mechanism
For electric-only mode, engine 1 does not work with generator 9, generator 9 and clutch 7
Cooling and lubricating is not needed, and electrodynamic pump 6 does not need work, and only motor 13 works,
Only need to cool down motor 13, the driving mechanical pump 18 of motor 13 is operated and by the
Two cooling oil passages 41 carry out cooling and lubricating to motor 13.
When automobile battery power is less than first threshold and Second Threshold, coupling mechanism controller coupling
Close the switch 35 of mechanics controller control the 3rd to open so that the 5th pipeline 28 disconnects, clutch
7 separation, now coupling mechanism, which is in, increases journey pattern, and engine 1, which starts, drives generator 9 to send out
Electricity is simultaneously not involved in driving, and electrodynamic pump 6 is operated and by the tie point of the first cooling oil passage
39 pairs of generators 9 carry out cooling and lubricating, while the driving mechanical pump 18 of motor 13 is operated
And cooling and lubricating is carried out to motor 13 by the second cooling oil passage 41.
When automobile battery power is more than first threshold and is less than Second Threshold, pass through coupling mechanism
The switch 35 of controller control the 3rd is closed, and connects the 5th pipeline 28 so that clutch 7 is engaged,
Engine 1 and generator 9 participate in driving, and now coupling mechanism is in hybrid mode, drive
The dynamic driving of motor 13 mechanical pump 18 works to carry out motor 13 cooling and lubricating, machinery
Pump 18 is that hydraulic pressure and flow that the 5th pipeline 28 can be provided are smaller, is not enough to control clutch,
Now start electrodynamic pump 6 and participate in work, clutch is controlled to ensure enough hydraulic pressure and flow
2, to meet the hydraulic demand of clutch 7, now, generator 9 and clutch 7 work,
The of the cooling oil passage of tie point 39 and first that electrodynamic pump 6 passes through the first cooling oil passage
Two branch roads 40 carry out cooling and lubricating to generator 9 and clutch 7.Due to being cooled oil
The influence of temperature and vehicle speed, the hydraulic pressure that electrodynamic pump 6 is produced can produce fluctuation therewith, in order to
Obtain enough and stable hydraulic pressure, it is necessary to according to the change of the temperature of cooling oil and speed to electricity
The motor speed (i.e. power output) of dynamic pump 6 is adjusted, to meet design requirement.
In order to meet the cooling and lubricating demand under the different operating modes of coupling mechanism, the control of the present embodiment
Method also includes step：When coupling mechanism, which is in, increases journey pattern or hybrid mode, obtain
The current speed of the temperature and automobile of cooling oil, is expired by adjusting the motor speed of electrodynamic pump 6
The cooling and lubricating demand of foot difference operating mode.It is in coupling mechanism and increases journey pattern or hybrid power mould
Under formula, when the temperature of cooling oil is higher, and speed it is very fast when, the motor of electrodynamic pump 6 should be improved
Rotating speed, to provide enough hydraulic pressure and flow for cooling and lubricating system；When cooling oil temperature compared with
During low and/or relatively low speed, the motor speed of electrodynamic pump 6 is controlled in less scope
The requirement of the hydraulic pressure and flow of cooling and lubricating system is met, cost thus can be reduced.
The control method of the present embodiment also includes step：Detect the temperature of cooling oil；Work as cooling oil
Temperature when being higher than threshold value, control first switch is opened, the oil outside the coupled mechanism of cooling oil
The first cooling oil passage and the second cooling oil passage are flowed into after cooling system cooling again with to coupling
The internal structure of mechanism carries out cooling and lubricating；When the temperature of cooling oil is less than threshold value, control the
One switch is closed, inner loop of the cooling oil in coupling mechanism.Specifically, first switch is passed through
33 judge the temperature of cooling oil, when the temperature of cooling oil is higher than threshold value, first switch 33
It will open and make it that the first pipeline 31 and the second pipeline 32 are in channel status, cooling oil passes through the
One pipeline 31 flows into cooler 30 and cooled down, and cold by the inflow first of the second pipeline 32
Oily passage and the second cooling oil passage 41, and enter the inside progress cooling profit of coupling mechanism
It is sliding；When the temperature of cooling oil is less than threshold value, first switch 33 is closed, and cooling oil is in coupling
The inside of mechanism is circulated.
The control method of the present embodiment also includes step：
Judge the oil pressure size of cooling oil；
When the oil pressure of cooling oil is higher than preset value, control second switch is opened, by the first pipe
Unnecessary cooling oil is back to oil supply system by oil return pipe 37 in road 31；
When the oil pressure of cooling oil is less than preset value, control second switch is opened, and cooling oil is complete
Portion is delivered to the inside of coupling mechanism by the first cooling oil passage and the second cooling oil passage 41
To carry out cooling circulation to the internal structure of coupling mechanism, it is not necessary to the backflow of cooling oil.
