The detecting assembly 15 includes a ring gear mechanism 151 and a wheel speed detecting member 152, and the cooperation of the ring gear mechanism 151 and the wheel speed detecting member 152 can realize the detection of the vehicle speed of the motorcycle 100. For clarity of description of the technical solution of the application, front, rear, left, right, up and down are also defined as shown in fig. 1.

As one implementation, the running assembly 12 includes a rim mechanism 123, with the brake disc 141 and the ring gear mechanism 151 each connected to the rim mechanism 123, with the ring gear mechanism 151 disposed between the brake disc 141 and the rim mechanism 123. In the present embodiment, the brake disc 141 is provided on the outer side of the ring gear mechanism 151 to facilitate the attachment and detachment of the brake disc 141 and the brake mechanism 142, so that the assemblability of the brake disc 141 and the brake mechanism 142 can be improved, which is advantageous in improving the assemblability of the brake assembly 14.

On the basis of the arrangement, the gear ring mechanism 151 is further arranged on the same side of the first part of the brake disc 141, so that a certain safety distance can be kept between the gear ring mechanism 151 arranged on the inner side and the brake mechanism 142, and the brake mechanism 123 can be prevented from interfering with the gear ring mechanism 151, thereby being beneficial to improving the working efficiency of the gear ring mechanism 151.

More specifically, suspension assembly 13 includes a connection end 133, connection end 133 being configured to connect to traveling assembly 12, connection end 133 being provided with a mounting point 1331, and mounting bracket 1421 being connected to suspension assembly 13 via mounting point 1331.

More specifically, the brake disc 141 includes a hollowed-out portion 1413, and the wheel speed detecting member 152 at least partially penetrates through the connecting end 133 and the hollowed-out portion 1413 to cooperate with the gear ring mechanism 151, so that the wheel speed detecting member 152 can realize a detecting function of the detecting hole 1513, that is, the detecting hole 1513 is in a detecting range of the wheel speed detecting member 152, so that the wheel speed detecting member 152 can detect a vehicle speed of the motorcycle 100 through the detecting hole 1513, thereby being beneficial to improving a detecting precision of the wheel speed detecting member 152, and further being beneficial to improving a detecting efficiency of the detecting assembly 15.

As shown in fig. 2, as an implementation, the ring gear body 1512 is substantially disposed in the hollowed out portion 1413 as viewed along the direction of the rotation axis of the ring gear mechanism 151.

Further, the ratio of the outer diameter D4 of the ring gear body 1512 to the outer diameter D5 of the disk 1412 is set to 0.41. With the above arrangement, interference with the mounting arrangement of the brake mechanism 142 due to the fact that the ratio of the outer diameter D4 of the ring gear body 1512 to the outer diameter D5 of the disc body 1412 is excessively large, which results in a smaller assembly space of the brake disc 141, can be avoided, thereby contributing to improvement of the assemblability of the brake mechanism 142 and the ring gear mechanism 151; it is also possible to avoid that the ratio of the outer diameter D4 of the ring gear body 1512 to the outer diameter D5 of the disc 1412 is too small, which results in too small an outer diameter D3 of the ring gear body 1512, so as to avoid that the detection accuracy of the detection assembly 15 is reduced due to too small a detection hole 1513 provided on the ring gear mechanism 151, which is further beneficial to improving the detection capability of the detection assembly 15.
