The rotation connection of second needle bearing 102；The shoulder portion 23 is rotatablely connected by needle roller thrust bearing 103 and the input shaft 1；
On input shaft 1 be arranged accommodating chamber 11 be nested in output shaft 12 in accommodating chamber 11, have compressed by above-mentioned design input shaft 1 with
Mounting structure between output shaft 2 makes input 1 complete to assemble with space as small as possible with output shaft 2, has saved space, full
Small foot dynamic coupling system, that is, P2 module axial space is problem.Pass through the first needle roller axis between input shaft 1 and output shaft 2
Hold 101 and second cooperation between needle bearing 102 to realize the mutual rotation between input shaft and output shaft 2.With it is defeated
Rotor is fixed on the outer hub 4 that shaft 2 is connected, when simple can make input shaft by clutch when using motor
Then rotor is separated between 1 and output shaft 2 drives output shaft 2 to rotate, and output shaft 2 passes through 101 He of the first needle bearing
Second needle bearing 102 is rotated around input shaft 1.Above-mentioned design makes the more smoothly operation during rotation of output shaft 2.
Since the play of output shaft 2 in axial direction will cause friction to influence the rotation of output shaft 2, the axis in output shaft 2
Be provided with needle roller thrust bearing 103 on direction, needle roller thrust bearing 103 can be avoided the axial float due to output shaft 12 and
Caused by rub.

Key 12；Interior hub 3 is fixedly connected by welding with input shaft 1, and the external splines 12 on input shaft 1 is used for and the internal spline on engine
Cooperation is to make hub 3 in engine driving rotate.
The outer hub 4 is fixedly connected with the output shaft 2, and the interior flower connecting with gearbox is provided on the output shaft 2
Key 24；Outer hub 4 is fixedly connected by welding with output shaft 2, and the internal spline 24 on output shaft 2 is used to match with the internal spline of gearbox
It closes.Then it controls the linkage between the interior hub 3 and the outer hub 4 by friction plate steel disc component 5 or separates.
Specifically, the friction plate steel disc component 5 is arranged between the outer hub 4 and the interior hub 3, the friction plate steel
Piece group 5 includes friction plate 51 and steel disc 52, and the friction plate 51 is fixedly connected with the interior hub 3, the steel disc 52 with it is described outside
Hub 4 is fixedly connected.Steel disc 52 is rotated with the rotation of outer hub 4, and friction plate 51 is rotated with the rotation of interior hub 3, passes through institute
It states piston 6 to control the linkage between friction plate 51 and steel disc 52 or separate, to hub 3 and the linkage of outer hub 4 or separate in realizing.
6 activity of piston is in following two states:
Linkage status: the direction of piston 6 described in hydraulic-driven to the close friction plate steel disc component 5 is mobile, to drive
The friction plate 51 fits with the steel disc 52, and the input shaft 1 links with the output shaft 2.Under the action of hydraulic, liquid
Pressure, which increases, pushes piston 6 to close to the movement of the direction of the friction plate assembly 5, and piston 6 drives friction plate 51 to be bonded with steel disc 52,
To make to generate linkage between friction plate 51 and steel disc 52, at the same between interior hub 3 and outer hub 4 due to friction plate 51 and steel disc 52 it
Between linkage generate linkage also to realizing that power is transmitted to output shaft 2 from input shaft 1.
Discrete state: driving the hydraulic reduction of the piston 6, and the piston 6 is to far from institute under the action of spring 7
The direction for stating friction plate steel disc component 5 is mobile, so that the friction plate 51 is separated with the steel disc 52, the input shaft 1 and institute
State the separation of output shaft 2.It drives the hydraulic reduction of piston piston under the action of spring 7 to be restored to original position, drives rub at this time
Pad 51 cancels to separate friction plate 51 with steel disc 52 with the power that steel disc 52 is bonded, so as to cause interior hub 3 and the outer hub 4
Separation, the driving force of input shaft 1 cannot be passed by output shaft 2.
Specifically, the clutch for hybrid vehicle further includes oil hydraulic system 9, to push the piston 6 to move
It is dynamic.The oil hydraulic system 9 includes oil pressure chamber 91 and oil pipeline 92, the oil pressure chamber 91 setting the piston 6 with it is described outer
Between hub 4, the oil pipeline 92 is arranged on the output shaft 2.
In use, hydraulic in increase hydraulic cavities 91 when needing to be driven using engine, it is hydraulic
