Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
The rear end cover assembly of the driving motor comprises a rear end cover body 1, and a junction box 2 and a rotary transformer box 3 which are arranged on the rear end cover body 1 and integrally formed with the rear end cover body 1, as shown in fig. 1 and 2. As shown in the figure, the rotary transformer box 3 is arranged in the middle of the rear end cover body 1, the rotary transformer box 3 comprises a rotary transformer box body 31 formed by extending the end face of the rear end cover body 1 outwards, the rotary transformer box body 31 extends upwards to form a junction box body 21, and a wire outlet 22 penetrating through the three-phase wire 6 is arranged on the side wall of the junction box body 21.
In the invention, a suspension boss 4 connected to the whole vehicle is arranged on one side of the rear end cover body 1. The lifting hole 5 is arranged at the corner of one side of the rear end cover body, preferably, the lifting hole is arranged at one side adjacent to the suspension boss 4, so that the arrangement is convenient, the space is saved, and the lifting operation is facilitated. In the invention, the suspension boss 4 and the hanging hole 5 are integrally formed with the rear end cover body 1.
According to the rear end cover assembly of the driving motor, the junction box sealing ring groove 24 for installing the sealing ring is formed in the upper end of the junction box body 21, so that connection and sealing are facilitated, and a good sealing effect is achieved. One side of the junction box body 21 is provided with a waterproof vent valve mounting hole 23.
