Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention provides Figure 1-5 The connecting device between the wheel hub motor and the wheel shown includes a wheel hub 4 and an outer rotor 1;

[0024] An outer rotor 1 is arranged on the left side of the inner wall of the wheel hub 4, and an outer tire 3 is arranged on the outer wall of the wheel hub 4;

[0025] Brushes 2 are arranged on the upper and lower sides of the inner wall of the hub 4;

[0026] Connecting blocks 14 are provided at the upper and lower ends of the inner wall of the hub 4 , a fixing block 12 is provided at the lower end of the connecting block 14 , and a brush 2 is provided at the lower end of the fixing block 12 . The brush 2 can rotate with the hub 4 to brush away dust on the outer wall of the outer rotor 1 .

[0027] When the outer rotor 1 transmits power to the wheel hub 4 to rotate the wheel hub 4 , the brush 2 will also rotate along with the wheel hub 4 , so that the dust and sand attached to the surface of the outer rotor 1 can be brushed away by the rotating brush 2 .

[0028] like Figure 4 As shown, a slider 16 is provided at the upper end of the fixed block 12, a fixing groove 13 is opened at the lower end of the connecting block 14, the fixed block 12 is inserted into the fixing groove 13 through the slider 16 and connected and fixed to the connecting block 14, a screw 15 is provided at the right end of the connecting block 14, the screw 15 is used to squeeze and fix the slider 16 in the fixing groove 13, and the brush 2 is made of high-tenacity fiber.

[0029] When the brush 2 is to be installed, the fixing block 12 can be fixed by inserting the slider 16 at the upper end into the fixing groove 13 at the lower end of the connecting block 14, so that the brush 2 is fixed to the upper and lower sides of the inner wall of the hub 4. The brush 2 made of high-tenacity fiber has stronger hardness and toughness, and can better brush away the mud and sand on the surface of the outer rotor 1.

[0030] like Figure 1 and Figure 2As shown, a wheel bearing 11 is arranged on the left side of the outer rotor 1, a single-tooth stator 10 is arranged on the left side of the wheel bearing 11, the single-tooth stator 10 is used to generate an excitation magnetic field to drive the wheel bearing 11 to rotate, a capacitor ring 9 is arranged on the left side of the single-tooth stator 10, a fixing ring 8 is arranged on the left side of the capacitor ring 9, the fixing ring 8 is used to fix the right capacitor ring 9 and the single-tooth stator 10, a shielding sealing shell 7 is arranged on the left side of the fixing ring 8, the shielding sealing shell 7 is used to encapsulate the outer rotor 1, and the shielding sealing shell 7 can also prevent the motor from leaking liquid and entering water.

[0031] The fixing ring 8, the capacitor ring 9, the single-tooth stator 10 and the wheel bearing 11 are fixed to the inner wall of the outer rotor 1 through the shielding sealing shell 7.

[0034] The working principle of the present invention is as follows: current is input through the capacitor ring 9 to make the single-tooth stator 10 generate an excitation magnetic field to drive the wheel shaft bearing 11 to rotate, thereby driving the wheel hub 4 to rotate. When there is a lot of mud, sand and dust, the fixing block 12 can be inserted into the fixing groove 13 at the lower end of the connecting block 14 through the slider 16 at the upper end and fixed by the screw 15, so that the brush 2 is fixed on the upper and lower sides of the inner wall of the wheel hub 4.
