After employing above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1) when rotor rotates, transmission oil warp beam sleeve oil-through-hole, chamber, piston oil-through-hole from input slinger
Got rid of with interior hub oil-through-hole to friction plate assembly, then through outer hub oil-through-hole and terminal pad oil-through-hole and through outer hub oil-through-hole and guarantor
Frame oil-through-hole is held, under the influence of centrifugal force, gets rid of the winding to motor, so as to reach cold using the transmission oil of lubricating friction plate
But the purpose of motor.
2) transmission oil is arranged in housing and keeps certain liquid level, rotor can stir speed change when rotating
Device oil, the cooling to motor stator both ends winding is realized with the mode of splash lubrication.

Embodiment
With reference to the accompanying drawings and embodiments, the present invention is further described.
As shown in Figure 1, input shaft 2, clutch 1, motor and interior hub input shaft 3 are installed in housing 0.Input shaft 2 with it is interior
Hub input shaft 3 is coaxially disposed；Input shaft 2 is used to introduce power inside speed changer, and interior hub input shaft 3 connects with engine flywheel
Connect.
Clutch 1 includes interior hub 18, outer hub 16 and is installed on friction plate assembly 17 between the two, and piston 11, returns
Position spring 14 and dummy piston 15.Outer hub 16 is fixedly connected with rotor input shaft, and interior hub 18 is welded on one with interior hub input shaft 3
Rise.Friction plate assembly 17 has known structure, is made of steel disc and friction plate, and steel disc is rotated with outer hub 16, friction plate
Rotated with interior hub 18, when both are pressed together, the moment of torsion in frictionally realization between hub 18 and outer hub 16 passes
Pass.
Motor includes stator 51 and rotor 52, and stator 51 is installed on housing 0, and rotor 52 is installed on rotor retainer 4,
Rotor retainer 4 is fixedly connected with rotor input shaft, and rotor input shaft is arranged and key connection is on input shaft 2.Rotor input shaft
It is a more complicated and important part, in the present embodiment, it is divided into two bodies, and a part is terminal pad 12, and one
Axle sleeve 13 is in part, both weld together, and such structure is primarily to facilitate processing and manufacturing.
Piston 11 is functionally named, but its shape is very different with common oil cylinder piston.Piston 11
Outer peripheral portion is the work department of square position shape, and the work department is corresponding to the working face position of friction plate assembly 17, that is to say, that piston
11 work department and friction plate assembly axial alignment, since the work department of piston 11 is square position shape, thus have less axis
To size.
