The transmission 20 and the electric motor 10 together define an angled space 40 to assist a half shaft (not shown) of the transmission to extend in an axial direction of the transmission. The controller 30, the transmission 20, and the electric motor 10 are integrated together. At least a part of the controller 30 is located in the angled space 40. A transmission shaft (not shown) of the transmission 20 is connected to the electric motor 10. The half shaft of the transmission 20 is mounted on the electric motor 10 and is located on the same side as the transmission 20, and the half shaft of the transmission 20 is parallel to the axial direction of the electric motor 10. The angled space 40 is located on a side of the electric motor 10 facing the half shaft of the transmission 20, and the angled space 40 is located on a side of the transmission 20 facing the electric motor 10. In other words, the angled space 40 abuts the side of the electric motor 10 facing the transmission 20 and the side of the transmission 20 facing the electric motor 10, respectively.It will be appreciated that an angle of the angled space enclosed by the electric motor 10 and the transmission 20 is less than 180 degrees.The controller 30 is mounted on at least one of the electric motor 10 and the transmission 20, and is electrically connected to the electric motor 10. The controller 30, the transmission 20, and the electric motor 10 are integrated together. The controller 30 includes a control body and a control bracket 31 located in the angled space 40.In the embodiment shown in FIGS. 2 to 5, the electric motor 10 is mounted on both the electric motor 10 and the transmission 20. The controller 30 is electrically connected to the electric motor 10. The controller 30 is configured to control start, stop, and a rotational speed, etc., of the electric motor 10. The control body is disposed in the angled space 40. It is to be appreciated that the control body refers to a function-carrying part of the controller 30, i.e., a part for achieving a control function, and does not include parts such as a mounted bracket. The controller 30 and the electric motor 10 are arranged on the same side of the transmission 20, and the controller 30 and the half shaft of the transmission 20 are arranged on the same side of the electric motor 10. The fact that the controller 30, the transmission 20, and the electric motor 10 are integrated together means that the controller 30, the transmission 20, and the electric motor 10 form one unit in a structural space. It should be appreciated that the electric motor 10 may be mounted not only on the controller 30 and the transmission 20, but may be mounted only on the controller 30 or only on the transmission 20.For the powertrain 100 according to an exemplary embodiment of the present disclosure, the angled space 40 is defined between the transmission 20 and the electric motor 10, and the controller 30, the transmission 20, and the electric motor 10 are integrated together, so that the powertrain 100 has a compact structure. The controller 30 is mounted on the transmission 20 and the electric motor 10. A three-phase wire connected between the controller 30 and the electric motor 10 is relatively short, and there is no need to arrange a relatively long connecting harness, thereby saving mounting space and causing the drive train 100 to be simple and pleasing as a whole. In addition, mounting points of the controller 30 to the frame are reduced, an overall vehicle structure is simplified, mounting operations are reduced, production cost and development cost are reduced, and the center of gravity of the powertrain 100 is lowered, so that the powertrain can be applied to a front-wheel drive vehicle and a rear-wheel drive vehicle.In addition, since the control body is disposed in the angled space 40, space of the angled space 40 may be used to move the controller 30 downward into the angled space 40, thereby reducing an overall height of the powertrain 100.Therefore, the powertrain 100 according to the embodiment of the present disclosure is characterized by advantages of a compact structure and a simple wire harness connection, etc.The powertrain 100 according to the embodiments of the present disclosure will be described in detail below with reference to FIGS. 2 to 7.In some embodiments of the present disclosure, as shown in FIG. 3, a lowest point of the control body is lower than a highest point of the electric motor 10 and / or a highest point of the transmission 20. When the highest point of the electric motor 10 is lower than the highest point of the transmission 20, the lowest point of the control 30 is lower than the highest point of the transmission 20. When the highest point of the electric motor 10 is higher than the highest point of the transmission 20, the lowest point of the control 30 is lower than the highest point of the electric motor 10.Specifically, the lowest point and the highest point are located in a direction perpendicular to a horizontal plane, that is, an up-down direction shown in FIG. 5. The lowest point of the controller 30 is the lowest point of the controller 30 in the up-down direction. The highest point of the electric motor 10 is the highest point of the electric motor 10 in the up-down direction. The highest point of the transmission 20 is the highest point of the transmission 20 in the up-down direction. The lowest point of the controller 30 is lower than the highest point of the electric motor 10 and / or the highest point of the transmission 20. Accordingly, a height of the unit formed by the controller 30, the electric motor 10, and the transmission 20 is smallest in the up-down direction shown in FIG. 3, so that an overall structure formed by the controller 30, the electric motor 10, and the transmission 20 is more compact and occupies a smaller space.In some embodiments of the present disclosure, as shown in FIGS. 2 to 5, the controller 30 is mounted over the half shaft.
