[0037] like Figures 1 to 4 As shown, an embodiment of the present invention provides an installation aid for an integrated electric drive rear axle drive motor, which includes a lifting mechanism 11, a positioning bracket 31, and two support brackets 21. The positioning bracket 31 is arranged on the right side of the top surface of the lifting platform 12 of the lifting mechanism 11, and the lifting platform 12 extends in the left and right directions; the positioning bracket has an arc-shaped positioning plate 32 with an opening facing upward, and the inner arc surface of the arc-shaped positioning plate 32 is used to fit with the outer circumferential surface of the mounting ring 42 of the rear axle reducer 41; the two support brackets 21 are both slidably arranged on the lifting platform 12 from left to right, and the support bracket 21 has an arc-shaped support plate 22 with an opening facing upward, and the opening of the arc-shaped support plate 22 is used to accommodate the drive motor 51.

[0038] The installation aid for the integrated electric drive rear axle drive motor provided in the embodiment of the present invention, when in use, can limit and support the drive motor by using the arc-shaped support plate 22 of the support bracket to prevent the drive motor from escaping from the support bracket; at the same time, the position of the lifting platform and the drive motor 51 in the up and down directions, that is, the vertical direction, can be conveniently adjusted through the lifting mechanism 11, and the positioning can be achieved by using the arc-shaped positioning plate 32 of the positioning bracket to cooperate with the mounting ring of the rear axle reducer. Since the support bracket is slidably arranged on the lifting platform 12, the position of the drive motor in the left and right directions can be conveniently adjusted, so that the installation position between the drive motor and the rear axle reducer is better, thereby making the assembly between the drive motor and the rear axle reducer more convenient, thereby improving the assembly efficiency.

[0039] Furthermore, an arc-shaped groove is provided on the inner arc surface of the arc-shaped support plate 22, and a plurality of balls 23 are rollingly provided in the arc-shaped groove. With this solution, the balls are in contact with the drive motor, so that the drive motor can be easily rotated, so that the position of the drive motor can be adjusted better according to the actual installation requirements, so that the installation position between the drive motor and the rear axle reducer is optimal, so that the installation of the drive motor and the rear axle reducer is more convenient, and the assembly efficiency can be further improved.

[0040] In one embodiment, the installation aid of the integrated electric drive rear axle drive motor further includes a first slide rail 61 and a second slide rail 62, the first slide rail and the second slide rail are arranged on the top surface of the lifting platform 12 in a front-to-back manner, the first slide rail and the second slide rail both extend in the left-right direction, two first sliders 611 are slidably arranged on the first slide rail 61, and two second sliders 621 are slidably arranged on the second slide rail 62; the first connecting block 24 and the second connecting block are respectively vertically arranged on the front and rear sides of the outer arc surface of the arc-shaped support plate 22, the lower end of the first connecting block 24 is provided with a first mounting block 25 for connecting with the first slider, and the lower end of the second connecting block is provided with a second mounting block 26 for connecting with the second slider. With this solution, the sliding arrangement of the two support brackets on the lifting platform is conveniently realized.

[0041] Specifically, the first slide rail 61 and the second slide rail 62 are detachably connected to the lifting platform respectively; the first mounting block is detachably connected to the first slider, and the second mounting block is detachably connected to the second slider, so that each component can be easily replaced or repaired.

[0042] Preferably, at least two groups of mounting holes 121 for connecting to the first slide rail are provided on the front side of the top surface of the lifting platform 12. With this solution, the first slide rail can be connected to different groups of mounting holes on the front side of the top surface of the lifting platform as needed to adjust the position of the first slide rail in the front-to-back direction, thereby expanding the scope of application of the mounting aid, so that it can be suitable for the installation of drive motors of different sizes. It can be understood that each group of mounting holes can include two mounting holes arranged opposite to each other on the left and right, and the first slide rail is provided with two connecting holes corresponding to the two mounting holes one by one, and the first slide rail is connected to the support platform by bolts; each group of mounting holes is arranged at intervals from front to back.

[0043] Specifically, at least two groups of mounting holes for connecting with the second slide rail are provided on the rear side of the top surface of the lifting platform 12. With this solution, the second slide rail can be connected to different groups of mounting holes on the rear side of the top surface of the lifting platform as required to adjust the position of the second slide rail in the front-to-back direction, thereby further expanding the applicable scope of the installation aid and improving the versatility of the installation aid.

[0044] Preferably, the first mounting block is connected to the first slider by bolts, and the second mounting block is connected to the second slider by bolts. Different support brackets can be used according to different sizes of the drive motor, thereby making the mounting aid more versatile.

[0045] Specifically, the positioning bracket 31 also includes a support plate 33 and a connecting plate 34. The upper end of the support plate is connected to the middle position of the outer arc surface of the arc-shaped positioning plate, and the lower end of the support plate is vertically connected to the connecting plate.

With this solution, since the positioning bracket and the lifting platform are bolted, positioning brackets of different sizes can be selected and connected to the lifting platform according to different rear axle reducers, so that the arc-shaped positioning plate can fit the outer circumferential surface of the mounting ring of the corresponding rear axle reducer, thereby improving the versatility of the installation aid.

[0046] Furthermore, the lifting mechanism includes a lifting scissors fork 16, a driving mechanism for driving the lifting scissors fork to rise and fall, and a support frame 17 for supporting the lifting scissors fork. The upper end of the lifting scissors fork is rotatably connected to the bottom surface of the lifting platform 12, and the lower end of the lifting scissors fork is rotatably connected to the support frame 17. With this solution, the lifting scissors fork can be driven to rise and fall by the driving mechanism, so that the lifting platform can be raised and lowered accordingly, so that the driving motor located on the lifting platform can also rise and fall accordingly. It can be understood that the lifting scissors fork is a common component in the prior art, and the driving mechanism can be a hydraulic cylinder 18, which will not be repeated here.

[0047] Specifically, rollers 19 are provided on the bottom surface of the support frame 17 so that the lifting mechanism can be easily moved.

[0048] Preferably, an inverted U-shaped handle 15 is vertically provided on the left side of the support frame, so that the lifting mechanism can be pushed to move on the ground more conveniently through the handle.

[0049] Specifically, a control box 13 is provided on the handle 15, and a manual lifting control button 14 for controlling the driving mechanism is provided on the control box, so that the lifting and lowering of the lifting platform can be controlled by the manual lifting control button, thereby making the operation of the installation auxiliary device more convenient.

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

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

[0052] Push the drive motor to the right. At this time, each slider slides to the right on each slide rail, so that the drive motor 51 is close to the mounting ring of the rear axle reducer. Slightly rotate the drive motor around the axis of the drive motor. At this time, the ball rolls, so that the spline sleeve of the drive motor 51 is connected to the spline shaft of the rear axle reducer 41. After connection, the drive motor is slowly moved to the right again, so that the mounting plate of the drive motor is attached to the mounting ring of the rear axle reducer and all mounting points are aligned, and then screw the bolts into each mounting point to complete the assembly of the drive motor and the rear axle reducer.

[0053] The mounting aid of the integrated electric drive rear axle drive motor of the present invention can improve the assembly quality of the drive motor and the rear axle reducer, reduce the cost of after-sales maintenance; improve the convenience during disassembly and assembly, save manpower; reduce the assembly cycle, and improve production capacity.
