[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 4 As shown, this embodiment provides a special disassembly device for a wheel hub bearing assembly, used to separate the wheel hub bearing assembly 10 from the motor assembly 20. Specifically, it includes a connecting body 1, a jack 5, a support base 6, and a top pin 7. The connecting body 1 is fixedly connected to the wheel hub bearing assembly 10. The support base 6 is located below the connecting body 1. The jack 5 is fixedly installed on the top of the support base 6, and the top pin 7 is installed on the bottom of the support base 6. The bottom of the top pin 7 passes through the wheel hub bearing through hole of the wheel hub bearing assembly 10 and is supported on the upper end face of the upper end cover of the motor assembly 20.

[0021] In this embodiment, a lifting eye screw 3 is installed on the top of the connector 1.

[0022] In this embodiment, the connecting body 1 is fixedly connected to the wheel hub bearing assembly 10 by the pressure plate 8 and the bolts on the upper part of the wheel hub bearing assembly 10.

[0023] In this embodiment, the connecting body 1 includes two ear plates 11 arranged in a cross shape. A connecting post 12 is fixed to each end of the ear plate 11, and a ring plate 13 is connected to the lower end of the connecting post 12. A circular plate 14 is fixed below the ear plate 11. The components can be connected by welding. The circular plate 14 is located at the position where the cylinder head rests, and it serves as a reinforcement.

[0024] In this embodiment, the top of the support base 6 is fixedly connected to the jack 5 by screws 2 and cover plate 4 to ensure that the jack 5 is fixed and stable during use.

[0025] In this embodiment, the bottom of the support base 6 is provided with a threaded hole for installing the top pin 7.

[0026] The working principle of the above structure:

[0027] During operation, after assembling the device 0 according to the above assembly relationship and connecting it to the product, operate the jack 5 to lift the connecting body 1 upward. Since the connecting body 1 is fixedly connected to the wheel hub bearing assembly 10, it will drive the wheel hub bearing assembly 10 to move upward. Meanwhile, the motor assembly 20 below is held down by the combination of screw 2, cover plate 4, jack 5, support base 6, and top pin 7. Finally, the wheel hub bearing assembly 10 and the motor assembly 20 can be separated. Then, use the hoisting equipment to lift the lifting eye screw 3 to lift the assembly of the connecting body 1 and the wheel hub bearing assembly 10 onto the operating table. This separates the special device from the product, and then subsequent maintenance operations are performed.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
