[0050] The general use process of the installation aid for the integrated electric drive rear axle drive motor provided by the embodiment of the application is as follows:

[0051] The drive motor 51 is placed in the opening of the two support brackets 21, and the position of the drive motor 51 in the up-down direction is adjusted by the lifting mechanism 11. When the positioning bracket 31 is in contact with the outer circumferential surface of the mounting ring 42 of the rear axle reducer 41, the lifting mechanism stops lifting the drive motor;

[0052] The drive motor is pushed to the right, and at this time, each sliding block slides to the right on each sliding rail, so that the drive motor 51 approaches the mounting ring of the rear axle reducer. The drive motor is slightly rotated around the axis of the drive motor, at this time, the balls roll, so that the spline sleeve of the drive motor 51 is inserted into the spline shaft of the rear axle reducer 41. After insertion, the drive motor is slowly moved to the right, so that the mounting disc of the drive motor is in contact with the mounting ring of the rear axle reducer while each mounting point is aligned, and then a bolt is screwed into each mounting point, that is, the assembly of the drive motor and the rear axle reducer is completed.
