The housing of the Electric drive module of current P2 hybrid power system is hollow structure, generally by
Aluminium alloy casting forms.In order to install the actuator 6 of clutch, as it is shown in figure 1, in housing 1
Being provided with midfeather 2, midfeather 2 has opening, for installing actuator 6.Coolant jacket 3
Having lug 4 with midfeather 2 opposite side, it is fixed on housing 1 by fixing bolt 7
One end on, the main body of coolant jacket 3 is assembled in housing by sealing ring 5.
Due to rigidity and the limited strength of aluminium alloy, the performance of housing 1 is restricted.In order to protect
Card housing 1 has enough rigidity and intensity, and midfeather 2 must have bigger thickness.So
One, the axial length of Electric drive module receives the restriction of the thickness of midfeather 2.And,
Owing to housing 1 has midfeather 2, the casting technique of housing 1 is complex, relatively costly.This
Outward, in order to manufacture the coolant jacket 3 with lug 4, needing thick-walled pipe as raw material, this will
Cause the waste of material.
Summary of the invention
It is an object of the invention to avoid the problems referred to above.To this end, according to the present invention, it is provided that Yi Zhong electricity
Driving module, it includes hollow housing, motor, cooling assembly and clutch, motor and clutch
Device is assemblied in described hollow housing, described cooling assembly have diapire and from diapire extend and with
The coolant jacket of one, described coolant jacket has lug in one end relative with diapire, its
It is fixed on shell one end, and the main body of described coolant jacket passes through sealing ring by hermetically
Being assemblied in hollow housing, and described diapire has opening, the actuator of described clutch is pacified
Dress is over said opening
According to embodiments of the invention, cooling assembly is fabricated by by deep draw process by steel disc.
According to embodiments of the invention, it is Z-shaped with chimb that cooling assembly is configured to cross section
Tube-like piece.
Preferably, described lug has through hole, and fixing bolt may pass through through hole to be fixed by lug
At shell one end.
Preferably, the opening of described diapire is provided around hole, and fixing bolt may pass through hole to promote
The installation of actuator.Reagency required during so can bearing clutch operating.
Preferably, sealing ring is assemblied between the inwall of housing and the main body of coolant jacket.
According to the present invention, also provide for a kind of cooling assembly for Electric drive module, described cooling
Assembly has diapire and extends from diapire and coolant jacket in conjunction, and described coolant jacket exists
With diapire opposite side, there is lug, and described diapire has opening.
Preferably, described lug has through hole.
According to the present invention, also providing for a kind of hybrid power system, it includes electromotor and as above institute
The Electric drive module stated, described Electric drive module one end is via described clutch and described electromotor
Coupling.
Idea of the invention is that, by the housing of the Electric drive module of traditional P2 hybrid power system
Midfeather and coolant jacket shape all-in-one-piece cool down assembly, cooling assembly and housing the two portion
The most such as it is bolted together between part.
According to the present invention, no longer having midfeather due to housing, the casting technique of housing obtains
Simplify.Be additionally, since cooling assembly by steel making, compared with the midfeather of conventional housings, cold
But diapire rigidity and the intensity of assembly is improved, and this can make the thickness of diapire be reduced,
Such that it is able to reduce the axial length of Electric drive module.Additionally, by steel disc is carried out deep-drawing
Manufacturing cooling assembly, the utilization rate manufacturing material have also been obtained raising.
