Describe in detail according to the power drive system 100 of the utility model embodiment below with reference to Fig. 1-Fig. 2, this power drive system 100 can be used as the power unit in hybrid vehicle, for driving Vehicle Driving Cycle.
Can comprise driving engine 1, power-transfer clutch 2, drive motor 3 and change-speed box 4 according to the power drive system 100 of the utility model embodiment.
Power-transfer clutch 2 is located between driving engine 1 and drive motor 3, and power-transfer clutch 2 is for engaging or disconnection driving engine 1 and drive motor 3.In other words, power-transfer clutch 2 is in the time of engagement state, and power can transmit between driving engine 1 and drive motor 3, and at power-transfer clutch 2 during in off-state, the power transmission between driving engine 1 and drive motor 3 will be interrupted.
Power-transfer clutch 2 can have A end, secondary part and clutch operation 22, power-transfer clutch 2 A ends can be connected with the bent axle of driving engine 1, power-transfer clutch 2 secondary parts can be connected with the motor shaft of drive motor 3, and clutch operation 22 can make the A end in tight stitching state separate with secondary part.Should be understood that, power-transfer clutch 2 has been prior art, and is well known for ordinary skill in the art, and therefore describes in detail no longer one by one for detailed structure and the principle of work of power-transfer clutch 2 here.
Drive motor 3 is connected with change-speed box 4, to transmit power.Particularly, the motor shaft of drive motor 3 carries out power with the input shaft of change-speed box 4 and is connected, and the input shaft of for example motor shaft and change-speed box 4 can pass through spline joint.Alternatively, drive motor 3 can be permagnetic synchronous motor.
Shown in Fig. 1-Fig. 2, driving engine 1, power-transfer clutch 2, drive motor 3 and change-speed box 4 are coaxially arranged, in other words, the central axis of the central axis of the rotation axis of the bent axle of driving engine 1, power-transfer clutch 2, drive motor 3 overlaps with the rotation axis of the input shaft of change-speed box 4.Thus, can reduce to a certain extent the axial dimension of power drive system 100.
And as shown in Figure 1, the motor casing of drive motor 3 31 is into a single integrated structure with the clutch case 21 of power-transfer clutch 2, in other words, motor casing 31 and clutch case 21 Integral designs, can further reduce the axial dimension of power drive system 100 like this.
Therefore, according to the power drive system 100 of the utility model embodiment, by by coaxially arranged to driving engine 1, power-transfer clutch 2, drive motor 3 and change-speed box 4, motor casing 31 adopts Integrated design mode with clutch case 21 simultaneously, thereby greatly reduce the axial dimension of power drive system 100, reduce layout difficulty, be convenient to be arranged in cabin.
As preferred embodiment, for example, on one end of the close power-transfer clutch 2 of motor casing 31 (, left end in Fig. 1), be formed with end cap, this end cap forms clutch case 21.Thus, save conventional clutch shell, end cap 21 has been formed to the housing of power-transfer clutch 2, thereby made the axial dimension of power drive system 100 compacter, reduced the quantity of parts, reduced quality and saved cost simultaneously.
Shown in seeing figures.1.and.2, drive motor 3 has terminals 32, and terminals 32 are fixed on motor casing 31, and a part for terminals 32 is positioned at motor casing 31 and another part stretches out outside motor casing 31.In other words, as shown in Figure 2, terminals 32 wear motor casing 31, and it is multiple that terminals 32 and the fixed form of housing can have, for example can be by being welded and fixed, screw thread is fixing etc.
For traditional power driving system, the terminals of its motor be all along motor shaft to and arrange, increased like this axial dimension.As preferred embodiment, according to an embodiment of the present utility model, as shown in Figure 2, the terminals 32 of drive motor 3, along the radially extension of drive motor 3, can further dwindle the axial dimension of power drive system 100 like this.
Further, clutch operation 22 is also arranged in end cap 21, and clutch operation 22 and terminals 32 positioned opposite, and for example clutch operation 22 and terminals 32 are in upwards positioned opposite of the footpath of drive motor 3.Thus, terminals 32 and clutch operation 22 take full advantage of the free space of motor casing 31 inside, and the two is non-interference, make drive motor 3 compacter with the structure at power-transfer clutch 2 places.Alternatively, clutch operation 22 can comprise the parts such as fork shaft and disengaging yoke, and clutch operation 22 has been also prior art, is not therefore describing in detail here.
The type of cooling of drive motor 3 can have multiple.For example can adopt air cooling type, can certainly adopt water cooled, or adopt air cooling type and water cooled simultaneously.In view of drive motor 3 can be used as power output source, its heat dissipation capacity may be larger, therefore preferably can adopt the mode of water-cooled.
For example, in one embodiment, in motor casing 31, be furnished with Coolant gallery, Coolant gallery can be distributed in whole motor casing 31, thereby increases the cooling performance to drive motor 3.
In certain embodiments, power-transfer clutch 2 can be electric control clutch, be that power-transfer clutch 2 is controlled by controller, change-speed box 4 can be automatic machincal transmission (, AMT), this electric control clutch 2 and this automatic machincal transmission 4 can be respectively and TCU(Transmission Control Unit, i.e. Automatic Transmission control unit) be connected, this electric control clutch 2 and this automatic machincal transmission 4 and TCU can be highly integrated, control policy are integrated in TCU simultaneously.
Adopt AMT change-speed box 4 can realize not cut-off clutch 2 and the action of shift gears has improved the ride comfort of shifting gears.
Generally speaking, little according to power drive system 100 compact conformations, the axial dimension of some preferred embodiments of the utility model, save arrangement space, can realize driving engine 1 with the parallel drive of drive motor 3, drive and the various modes such as common driving separately.Can also realize the quick start-stop of driving engine 1, optimize driving engine 1 operation point, but also had pure motor driving pattern, power-assisted drive pattern, reclaims the multiple mixed moving functions such as braking energy simultaneously.
In addition, further provide according to embodiment of the present utility model the vehicle that comprises power drive system 100 as above.Should be understood that, according to other configuration example of the vehicle of the utility model embodiment as driving system, steering swivel system, brake system etc. be all prior art and being well known for ordinary skill in the art, therefore the detailed description of conventional construction is omitted herein.
In the description of this specification sheets, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, to the schematic statement of above-mentioned term not must for be identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.In addition, those skilled in the art can engage the different embodiment that describe in this specification sheets or example and combine.
Although illustrated and described embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment in scope of the present utility model, amendment, replacement and modification.
