Technical field
The present invention relates to the technical field of structural partsof automobiles, is related specifically to new-energy automobile hybrid power transmission system
Oil pump integration field.
Background technology
Automobile is essential in routine work life as a kind of vehicles.Equally, it is in modern industry
Also take up irreplaceable position.
As country enters high-speed development period, the recoverable amount of automobile is growing.Subtract especially for response national energy-saving
Raising of the call and people of row to life comfortableness requirement, automatic catch automobile, the market of hybrid vehicle are growing, its
Core technology is also being constantly updated.In the vehicle of the mainstream automotive market such as America and Europe, Japan and Korea S and domestic motor market, hybrid power
The application that automobile carries automatic gear-box is also more and more.
For automatic gear-box, on the basis of traditional mechanical structure, clutch and planet are more applied
The structure of gear train, this just faces the problem of space characteristics of compact layout unavoidably；And hybrid power automatic gear-box is even more basic herein
On, the new part such as motor is added, its arrangement difficulty spatially is further increased.And need in narrow space
Meet the arrangement of various parts, it is also necessary to the hydraulic environment needed for gearbox entirety normal operating conditions is provided, to ensure to become
Fast case normal work during vehicle traveling.So how compact spatial design and arrangement oil pump turn into one it is intractable
Problem.
In the application of hybrid power system, because to meet the pattern switching of hybrid power system, in automatic gear-box
Clutch to meet the operating mode for combining, disconnecting, at this moment just need oil pump to provide oil pressure needed for clutch, by oil pump output
Hydraulic environment is combine clutch, disconnection.But in the power vehicle of mixing, under electric-only mode, because engine
Do not work the hydraulic environment for causing oil pump can not provide normal work to whole gearbox in motor start-up course, institute
Generally can all have a mechanical oil pump and an electrodynamic pump on hybrid power transmission system.But double oil pumps are dynamic in mixing
Arranged in power transmission system originally narrow space, it is even more extremely difficult, therefore propose the integrated scheme of oil pump.
The content of the invention
The technical problems to be solved by the invention are to realize a kind of mechanical oil pump by conventional hybrid transmission system
It is combined into one with electrodynamic pump, integrated operation of oil pump is driven in pure electronic operating mode or braking using small machine, supplies whole system
The hydraulic environment of system.
To achieve these goals, the technical solution adopted by the present invention is：Hybrid vehicle oil pump integrated system, starts
The output shaft of machine and the rotor of motor are connected by coupling mechanism with transmission system input shaft, the transmission system

Clutch apparatus, the rotor of the motor are provided between transmission system input shaft and Oil pump electrical machinery or oil pump input shaft
By being provided with clutch apparatus between coupling mechanism and Oil pump electrical machinery or oil pump input shaft.
Using hollow, the transmission system input shaft is coaxial set with oil pump input shaft at the central axis position of the oil pump
Structure, the hollow space of the transmission system input shaft through oil pump are connected with gearbox.
The clutch device is set to one-way clutch.
Based on the oil pump control method of the hybrid vehicle oil pump integrated system, during vehicle launch, Oil pump electrical machinery is first
Row work, drive integrated oil pump to provide hydraulic pressure demand to gearbox, can meet integrated oil pump just when the rotating speed of motor reaches
During the rotating speed often to work, Oil pump electrical machinery is stopped.
When Brake stop, when motor spinner velocity drops to the liquid that integrated oil pump can not be driven to supply whole system
During pressure ring border, Oil pump electrical machinery restarts work.
When vehicle is in electric-only mode, Oil pump electrical machinery prerequisite activity, integrated oil pump is driven to provide hydraulic pressure to gearbox
Demand, when the rotating speed of motor reaches the rotating speed that can meet integrated oil pump normal work, Oil pump electrical machinery is stopped.
When vehicle is in pure oily pattern, Oil pump electrical machinery prerequisite activity, oil pump is driven to provide system hydraulic pressure demand, when starting
Machine rotating speed reaches when can meet oil pump normal work, and Oil pump electrical machinery is stopped.
When vehicle is in parallel drive, Oil pump electrical machinery prerequisite activity, drives oil pump to provide system hydraulic pressure demand, work as parallel connection
Input speed reaches when can meet oil pump normal work, and Oil pump electrical machinery is stopped.
Mechanical oil pump in conventional hybrid transmission system and electrodynamic pump are combined into one by the present invention, not only in performance
Make the more centralization of its function, and be even more further optimization on its arrangement and its size.It is this to design functionally more
Add centralization, high efficiency, it is compacter in structure, gearbox overall space is made full use of, reduces amount of parts and cost,
And make it under pure electronic operating mode, before vehicle start, oil pump prerequisite activity is integrated, whole system hydraulic environment is supplied, avoids car
During starting, hydraulic system pressure and flow are unsatisfactory for the demand of transmission system.Upon actuation, reach can be with for motor rotating speed
When driving integrated oil pump, motor drives integrated oil while the output power required for being supplied to whole gearbox
Pump voltage supply, " efficient " is truly realized, the effect being optimal.
