As a key component of motorcycles, the performance of the wheel hub directly affects the driving safety and overall performance of the vehicle. During long-term use of the traditional wheel hub, the bearing is easily eroded by dust, moisture, impurities and other external factors, leading to accelerated wear and tear, shortened service life, and thus causing vehicle failure and threatening driving safety.

[0003] A motorcycle wheel hub is disclosed in Chinese Patent No. CN217863539U, which includes a rim, an outer periphery of the rim coaxially provided with a ring groove for embedding an outer tire and an inner tire, and a positioning groove provided on the surface of the rim along its axial direction for embedding a pry plate. The positioning groove penetrates the rim in a direction away from the axis of the rim. By embedding the pry plate into the positioning groove, the groove wall of the positioning groove restricts the pry plate from sliding along the circumference of the rim, thereby facilitating the installation of the outer tire or the inner tire.

[0004] However, the above-mentioned motorcycle wheel hub allows dust, sand and other impurities raised by the road surface to enter the bearing without any hindrance during use, which mixes with the lubricating grease to form an abrasive, accelerating the wear and tear of the balls, rollers and inner and outer rings, and significantly shortening the service life of the bearing.

[0027] When the bearing of the motorcycle hub 1 needs to be repaired, the staff only needs to untwist the sealing cover 2 to drive the locking mechanism 3 to be in contact with the inclined sliding surface of the locking groove 102 and be extruded out of the locking groove 102, and the extruded locking mechanism 3 will be retracted into the guide groove 201, and then the staff can rotate the sealing cover 2 from the outer surface of the threaded pipe 101, so that the installation and removal process only needs to be twisted to achieve, which is convenient for the staff to quickly check, repair or replace the bearing, and reduces the difficulty and cost of maintenance.

[0028] As shown in Figure 4 , the locking mechanism 3 includes an insertion block 303, the insertion block 303 is slidably installed in the guide groove 201, the insertion block 303 is in the shape of a trapezoid, a slide column 301 is fixedly installed in the guide groove 201, the slide column 301 is slidably inserted into the insertion block 303, and a spring 302 is sleeved on the outer surface of the slide column 301, and the two ends of the spring 302 are fixedly connected to one end in the guide groove 201 and one end of the insertion block 303, respectively.
