[0046] Please refer to Figure 1-Figure 6 This embodiment provides a transmission assembly housing, including a motor housing 100 , a reducer housing 200 and a sealing end cover 300 .

[0047] Specifically, a motor installation cavity 110 is formed in the motor housing 100, and a reducer installation cavity 210 is formed in the reducer housing 200. The motor installation cavity 110 is connected to the reducer installation cavity 210, so that the motor and the reducer can achieve transmission. Figure 5 As shown, the reducer housing 200 is provided with an input shaft hole 240, an intermediate shaft installation cavity 250 and a first output shaft hole 260. The reducer installation cavity 210 is connected to the motor installation cavity 110 through the input shaft hole 240, and the output shaft of the motor can be connected to the reducer through the input shaft hole 240, so as to transmit the power output by the motor to the reducer. The intermediate shaft installation cavity 250 can be used to install the intermediate shaft and the intermediate transmission gear to realize the transmission of power between the input shaft and the output shaft of the reducer. The first output shaft hole 260 can be used to install the output shaft of the reducer. The sealing end cover 300 is arranged on the side of the reducer housing 200 away from the motor housing 100. After the sealing end cover 300 is connected to the reducer housing 200, the reducer is kept relatively sealed from the external environment. The sealing end cover 300 is provided with a second output shaft hole 330 corresponding to the first output shaft hole 260.

The above arrangement can reduce the process steps for assembling the motor housing 100 and the reducer housing 200, which is beneficial to reducing the overall weight of the transmission assembly housing and reducing costs.

[0049] In a possible implementation manner, the motor housing 100 and the reducer housing 200 of this embodiment may be integrated by casting, and casting is used to facilitate improving the production efficiency of the motor housing 100 and the reducer housing 200.

The second body 221 is provided with a plurality of second reinforcing ribs 223 to improve the overall strength of the second bracket 220.

[0054] The first bracket 120 and the second bracket 220 of this embodiment can be connected to the controller through the first connecting portion 122 and the second connecting portion 222. For example, a through hole for passing a fastening screw can be provided on the controller, and the fastening screw is locked into the first threaded hole or the second threaded hole after passing through the through hole, thereby achieving connection and fixation of the controller.

[0055] In one possible implementation, Figure 3 and Figure 6As shown, along the second direction Y, the reducer housing 200 of this embodiment is further provided with a third bracket 230 at one end away from the motor housing 100. The sealing end cover 300 is provided with a fourth bracket 310 at one end away from the reducer housing 200. The third bracket 230 and the fourth bracket 310 are used to connect the vehicle body, thereby fixing the transmission assembly housing on the vehicle body.

[0056] In this embodiment, the third bracket 230 is formed as an integral part with the reducer housing 200, and the fourth bracket 310 is formed as an integral part with the sealing end cover 300. Through the above arrangement, compared with the method of separately arranging the third bracket and the reducer housing, and separately arranging the fourth bracket and the sealing end cover, this embodiment further reduces the assembly process of the transmission component housing, thereby helping to reduce the overall production cost and improve production efficiency.

[0057] Further, in this embodiment, the third bracket 230 includes a third body 231 and a third connecting portion 232.

The fourth connecting portion 312 may be cylindrical and have a fourth threaded hole therein. The fourth body 311 is provided with a plurality of fourth reinforcing ribs 313 to improve the overall strength of the fourth bracket 310.

[0059] The third bracket 230 and the fourth bracket 310 of this embodiment can be connected to the vehicle body through the third connection part 232 and the fourth connection part 312. For example, the front suspension can be fixed to the third threaded hole in the third connection part 232 by fastening screws, and the left suspension can be fixed to the fourth threaded hole in the fourth connection part 312 by fastening screws, so as to realize the connection and fixation between the transmission assembly housing and the vehicle body.

[0060] Please continue to refer to Figure 1 , Figure 5 and Figure 6In a possible implementation, the sealing end cover 300 of this embodiment is detachably connected to the reducer housing 200.

When disassembly is required, the sealing end cover 300 and the reducer housing 200 can be separated by simply removing the fasteners.

[0061] In order to facilitate the movement of the transmission assembly housing, the sealing end cover 300 of this embodiment is also provided with a plurality of lifting holes 320, through which the lifting equipment can lift the transmission assembly housing and then move it to a preset position to improve the handling efficiency.
