Specifically, referring to fig. 6, since the interconnector 100 has a thin plate structure, the resistance to deformation is poor, and the deformation amount at the bearing mounting holes (i.e., the input shaft bearing mounting hole 102, the first output shaft bearing mounting hole 103, and the second output shaft bearing mounting hole 104 described above) is the largest through CAE stiffness analysis, the height of the reinforcing ribs arranged therearound in the thickness direction of the interconnector 100 is relatively high, and the reinforcing ribs arranged around the bearing mounting holes are arranged in a radial shape, the peripheral walls of the plurality of reinforcing rib bearing mounting holes are formed in a triangular structure, and the reinforcing ribs arranged around the two bearing mounting holes are arranged along the central connecting line of the two bearing mounting holes.

Similarly, the span of the two positioning holes 113 of the middle yoke plate 100 is larger through analysis, in order to avoid the differential, an arc structure is adopted, and the structure around the bearing hole is deformed due to the easy deformation of the middle yoke plate 100, so that a plurality of reinforcing ribs around the two positioning holes 113 are arranged along the central connecting line of the two positioning holes 113.

Further, a first output shaft (not shown) may be supported at the first output shaft bearing mounting hole 103 by using a tapered roller bearing, and a second output shaft may be supported at the second output shaft bearing mounting hole 104 by using a tapered roller bearing, so that when the tapered roller bearing receives radial and axial loads from the output shafts (i.e. the first output shaft and the second output shaft described above), the tapered roller bearing may be pressed in the bearing mounting holes, and at this time, neither the first output shaft bearing mounting hole 103 nor the second output shaft bearing mounting hole 104 needs to be provided with the bearing rotation-preventing structure 1021; the input shaft can be supported at the input shaft bearing mounting hole 102 by adopting a deep groove ball bearing, at this time, a bearing anti-rotation structure 1021 needs to be arranged at the input shaft bearing mounting hole 102, meanwhile, a bearing pressing plate 115 is arranged at one end, located at the first surface 101, of the input shaft bearing mounting hole 102, a plurality of pressing plate bolt holes 1151 can be formed in the bearing pressing plate 115, the plurality of pressing plate bolt holes 1151 are arranged at intervals along the periphery of the pressing plate, and the bearing pressing plate 115 can be connected with the first surface 101 through bolts.

Here, referring to fig. 1 and fig. 3, it should be noted that, in principle, the extending directions of the clutch lubricating oil passage 106b, the first clutch control oil passage 106c and the second clutch control oil passage 106d should be as parallel as possible, so that interference is not generated during core pulling, but in practice, the spatial angles of the clutch lubricating oil passage 106b, the first clutch control oil passage 106c and the second clutch control oil passage 106d are not consistent for the following reasons: firstly, because the seal groove at the clutch main hub is designed to be an axially continuous three-groove structure, the axial heights of the outlets 1066 of the oil passages 106 corresponding to the middle connecting plate 100 are different, and in order to ensure the wall thickness of each oil passage 106, the oil passages 106 are spatially staggered from each other (for example, the outlets 1066 of the three oil passages on the inner wall of the input shaft bearing mounting hole shown in fig. 3); secondly, since the second bolt hole 112 between the two shift fork cylinder oil passages 106a and the clutch oil passage (i.e., the clutch oil passage 106b, the first clutch control oil passage 106c, and the second clutch control oil passage 106d) occupies a space, the entire box space is limited. The shifting fork cylinder oil passages 106a do not have the problems, and a core-pulling mode can be adopted during die casting of the long oil passage 106 to avoid casting defects, so that the air tightness of the oil passage 106 is guaranteed.

According to some embodiments of the present invention, refer to fig. 1 and 5, the electronic pump oil duct 109 is further formed in the middle header plate body 1, the electronic pump oil duct 109 extends in the middle header plate body 1, one end of the electronic pump oil duct 109 is suitable for being communicated with the suction filter 3 located at one side of the first surface 101 of the middle header plate 100, the other end of the electronic pump oil duct 109 is communicated with the electronic pump located at the other side of the second surface of the middle header plate 100, thus, the oil filtered by the suction filter 3 enters the electronic pump at the side of the clutch housing through the electronic pump oil duct 109, then the oil entering the electronic pump enters the hydraulic module at the side of the transmission housing 2 through the connection oil duct (not shown) of the clutch housing and the transmission housing 2, and finally the oil in the hydraulic module is supplied to the clutch and the shift fork cylinder through the plurality of oil ducts 106 on the middle header plate 100.
