[0037] The housing includes a motor housing 7, a front housing 1 and a rear housing 28; wherein the input shaft 15 is rotatably supported in the motor housing 7 by two needle bearings 16, for example, the end of the motor housing 7 close to the input shaft 15 extends a predetermined distance along the axial direction of the input shaft 15 to form a lower extension, and the end of the motor housing 7 away from the input shaft 15 is fixed to the front housing 1, with reference to Figure 1In this embodiment, the end of the motor housing 7 away from the input shaft 15 also extends a predetermined distance along the axial direction of the input shaft 15 to form an upper extension portion, so that the motor housing 7 is located inside the front housing 1; the front housing 1 is arranged parallel to the axis of the input shaft 15, and the rear housing 28 is fixed to the right end of the front housing 1, and the rear housing 28 is arranged perpendicular to the axis of the input shaft 15.

[0038] The motor includes a motor stator 2 and a motor rotor 3, wherein the motor stator 2 is fixed to the upper extension portion of the motor housing 7; the motor rotor 3 is fixed to the rotor bracket 8, and the rotor bracket 8 is rotatably supported on the lower extension portion of the motor housing 7 by two angular contact ball bearings 17; in this embodiment, the angular contact ball bearings 17 are pre-tightened and axially positioned by a locking nut 18.

[0039] The first clutch 4 , the second clutch 5 and the third clutch 6 are arranged side by side inside the rotor bracket 8 , that is, the first clutch 4 , the second clutch 5 and the third clutch 6 are respectively located on both sides of the rotor bracket 8 relative to the motor rotor 3 .

[0040] The first clutch 4, the second clutch 5 and the third clutch 6 are integrated with the rotor support 8, so as to reduce the axial size and the number of parts of the motor and clutch integration device of this embodiment.

[0041] Specifically, the friction plate 30 of the first clutch is connected to the input shaft 15 by a spline, and the steel plate 29 of the first clutch is connected to the rotor bracket 8 by a spline; the cylinder body of the first clutch hydraulic cylinder 23 is fixed to the motor housing 7, and the piston of the first clutch hydraulic cylinder 23 is connected to the first clutch pressure plate 12 through the first clutch release bearing 13, and the first clutch pressure plate 12 passes through the rotor bracket 8 and contacts with the steel plate 29 of the first clutch. When the piston of the first clutch hydraulic cylinder 23 moves to the right, the steel plate 29 of the first clutch is pushed to move to the right through the first clutch pressure plate 12, thereby contacting the friction plate 30 of the first clutch, so that the first clutch 4 is engaged, and the power of the engine is transmitted to the rotor bracket 8 through the input shaft 15 and the first clutch 4. A sliding support structure 38 is provided between the first clutch pressure plate 12 and the rotor bracket 8 for guiding and positioning the first clutch pressure plate 12.

[0042] A spring element 31 is provided between the steel plates 29 of the first clutch. The spring element 31 is preferably a wave spring or a butterfly spring. When the first clutch 4 is not needed to work, the first clutch 4 is separated to cut off the power input of the engine. The first clutch 4 is axially fixed inside the rotor bracket 8 by a retaining ring 32, and the retaining ring 32 is a series of optional retaining rings, that is, by adjusting the thickness of the retaining ring 32, the distance between the friction plate 30 of the first clutch and the steel plate 29 of the first clutch can be adjusted.

[0043] The steel plate 33 of the second clutch is connected to the rotor bracket 8 through a spline, the friction plate 34 of the second clutch is connected to the first output shaft 19 through a spline, one end of the first output shaft 19 is rotatably supported in the input shaft 15 through a needle bearing, and the other end of the first output shaft 19 is connected to the transmission input shaft through a spline (not shown in the figure).

[0047] The third clutch pressure plate is provided with a plurality of arc-shaped holes along the circumferential direction; in the present embodiment, preferably, the arc-shaped holes are evenly distributed along the circumference of the third clutch pressure plate, and the number of the arc-shaped holes may be 8; and the steel plate of the third clutch is also provided with arc-shaped holes at positions relative to the arc-shaped holes of the third clutch pressure plate.

[0048] The second clutch pressure plate 26 is provided with a claw that matches the circular arc hole. The claw passes through the circular arc holes of the third clutch pressure plate 27 and the steel plate 35 of the third clutch and contacts the steel plate 33 of the second clutch. Therefore, when the second clutch pressure plate 26 moves axially to the left, it can push the steel plate 33 of the second clutch to move, and make the steel plate 33 of the second clutch contact with the friction plate 34 of the second clutch, thereby realizing the power transmission of the second clutch 5. The power of the motor or engine is transmitted to the input shaft of the transmission through the rotor bracket 8, the second clutch 5 and the first output shaft 19. A spring element 31 is provided between the steel plates 33 of the second clutch. The spring element 31 is preferably a wave spring or a butterfly spring. When the second clutch 5 is not needed to work, the second clutch 5 is separated. At this time, the second clutch pressure plate 26 moves to the right to disconnect the power transmission.

[0049] In this embodiment, preferably, an adjustment washer 37 is provided between the second clutch release bearing 25 and the piston of the second clutch hydraulic cylinder 24. The adjustment washer 37 is a washer with optional thickness and is used to adjust the distance between the steel plate 33 of the second clutch and the friction plate 34 of the second clutch. Similarly, an adjustment washer 22 is provided between the third clutch release bearing 21 and the piston 23 of the third clutch hydraulic cylinder. The adjustment washer 22 is a washer with optional thickness and is used to adjust the distance between the steel plate 35 of the third clutch and the friction plate 36 of the third clutch.

[0050] More preferably, the sliding support sheet 39 includes a first arc portion 391 , a second arc portion 392 and a fixing column 393 .

In this embodiment, the first arc portion 391 and the second arc portion 392 can be formed as one piece.

[0052] One end of the fixing column 393 is fixed to the first arc portion 391 . Preferably, the fixing column 393 is perpendicular to the first arc portion 391 , and the fixing column 393 and the second arc portion 392 are located on the same side of the first arc portion 391 .

[0053] A plurality of mounting holes are provided on the second clutch pressure plate 26. In the present embodiment, the mounting holes are evenly distributed along the circumference of the second clutch pressure plate 26, and the fixing columns 393 of the sliding support plate 39 are fixed in the mounting holes, so that the sliding support plate 39 is located between the second clutch pressure plate 26 and the third clutch pressure plate 27, and its upper surface and lower surface are in contact with the third clutch pressure plate 27 and the second clutch pressure plate 26 respectively, that is, the second clutch pressure plate 26 is radially positioned and axially guided by the sliding support plate 39.
