[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 7 As shown, an embodiment of the present invention proposes a driving bearing for a new energy vehicle, including a bearing body 1, the bearing body 1 including an outer ring 101 and an inner ring 102, the inner ring 102 is movably located inside the outer ring 101, a retaining frame 4 is movably installed between the outer ring 101 and the inner ring 102, and balls 5 are movably installed inside the retaining frame 4, and the balls 5 are fitted between the outer ring 101 and the inner ring 102, and baffles 2 are respectively installed at the upper and lower ends of the inner parts of the outer ring 101 and the inner ring 102, and an auxiliary mechanism 3 is installed between the baffle 2 and the inner ring 102.

[0026] like Figure 4 As shown, in another embodiment of the present invention, the auxiliary mechanism 3 includes a plurality of connecting frames 301, and the plurality of connecting frames 301 are equidistantly installed on the upper and lower sides of the inner ring 102. A placement groove 304 is provided on the side of the connecting frame 301 close to the baffle 2. A brush 305 is installed inside the placement groove 304. The brush 305 fits the surface of the outer ring 101, the inner ring 102 and the baffle 2. A brush 305 is provided between the end of the connecting frame 301 away from the outer ring 101 and the inner ring 102. The No. 1 threaded hole 302 is overlapped with each other, and the No. 1 threaded holes 302 that overlap with each other are respectively installed with No. 1 bolts 303 through threads. The side of the baffle 2 away from each other is respectively provided with a temporary groove 306, and the interior of the temporary groove 306 is respectively penetrated with a connecting hole 307. A sealing block 308 is respectively installed between the temporary groove 306 and the connecting hole 307. The sealing block 308 is located at one end of the interior of the temporary groove 306 and close to one end of the connecting hole 307. The cam 314 is provided with a plurality of spacers 316 on each side of the cam 316, and the spacers 316 are connected to the cam 316 by a plurality of screw threads 314 on each side of the cam 316. The cam 316 is provided with a plurality of spacers 316 on each side of the cam 316. The cam 316 is provided with a plurality of spacers 316 on each side of the cam 316.

[0027] The user places the connecting frame 301 on the surface of the bearing body 1 and makes the No. 1 threaded holes 302 overlap with each other. Then the user can install the No. 1 bolt 303 through the thread to realize the positioning of the connecting frame 301, so that the connecting frame 301 and the inner ring 102 are connected, and the connecting frame 301 drives the brush 305 and the outer ring 101, the baffle 2 and the inner ring 102 to fit together, so that when the shaft drives the inner ring 102 to rotate in the later stage, the inner ring 102 can drive the connecting frame 301 to rotate, so that the connecting frame 301 drives the brush 305 to start cleaning the surface of the baffle 2 and the outer ring 101 and the gap between the baffle 2, the outer ring 101 and the inner ring 102, so as to prevent dust and the like from accumulating inside the gap, and better protect the bearing body 1 and the lubricating oil inside the bearing body 1;

[0028] When it is necessary to add lubricating oil to the inside of the bearing body 1, the user only needs to remove the No. 2 bolt 316, and then the spring 315 will push the extrusion plate 317 and the positioning frame 312 to move, so that the positioning frame 312 is separated from the inside of the positioning groove 313. Then the user can remove the sealing block 308 and add lubricating oil through the connecting hole 307, thereby reducing the contact area between the inside of the bearing body 1 and the outside air, preventing dust and the like from entering the inside of the bearing body 1 during the process of adding lubricating oil, and better protecting the lubricating oil;

[0029] Then, after the lubricating oil is added, the user can put the sealing block 308 back into the temporary storage groove 306 and the connecting hole 307 for sealing, and then the user installs the No. 2 bolt 316. Then, as the No. 2 bolt 316 moves, the No. 2 bolt 316 is pushed toward the positioning frame 312 through the inclined surface of the upper end of the positioning frame 312, so that the positioning frame 312 cooperates with the extrusion plate 317 to squeeze the spring 315, and at the same time, the positioning frame 312 is also stuck in the interior of the positioning groove 313 to achieve a positioning effect, thereby improving the stability of the sealing block 308.

[0030] The working principle of the drive bearing of a new energy vehicle:

[0031] When in use, the user first places the connecting frame 301 on the surface of the bearing body 1 and allows the No. 1 threaded holes 302 to overlap. Then the user can install the No. 1 bolt 303 through the thread to achieve the positioning of the connecting frame 301, connect the connecting frame 301 and the inner ring 102, and allow the connecting frame 301 to drive the brush 305 and the outer ring 101, the baffle 2 and the inner ring 102 to fit together, so that when the rotating shaft drives the inner ring 102 to rotate in the later stage, the inner ring 102 can drive the connecting frame 301 to rotate, and allow the connecting frame 301 to drive the brush 305 to start cleaning the surface of the baffle 2 and the outer ring 101 and the gap between the baffle 2, the outer ring 101 and the inner ring 102 to avoid dust and the like from accumulating inside the gap, and better protect the bearing body 1 and the lubricating oil inside the bearing body 1.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
