[0035] In the embodiment, the two sides of the conversion shell 1 are provided with a sliding groove 11 for the movement of the sliding axle 2, and the two ends of the sliding axle 2 are arranged in the sliding groove 11, so that the sliding axle 2 can move along the sliding groove 11 and can guide and limit the movement of the sliding axle 2.

[0036] In the embodiment, the sliding axle 2 is provided with a conversion joint assembly 3 for driving connection with the cable of the motorcycle rear brake system and the cable of the motorcycle front brake system, and the cable of the motorcycle rear brake system, the cable of the motorcycle hand brake and the cable on the front wheel brake of the motorcycle are connected to the sliding axle 2 through the conversion joint assembly 3.

[0037] In the embodiment, the cable of the motorcycle front brake system includes the cable of the motorcycle hand brake and the cable of the front wheel brake of the motorcycle, the conversion joint assembly 3 includes a cable joint I 31 driving connected with the cable of the motorcycle rear brake system, a cable joint II 32 driving connected with the cable of the motorcycle hand brake and a cable joint III 33 driving connected with the cable of the front wheel brake of the motorcycle, when the motorcycle front brake system works, the cable drives the sliding axle 2 to move through the cable joint II 32, so that the cable of the front wheel brake of the motorcycle moves to brake the front wheel of the motorcycle, when the motorcycle rear brake system works, the cable drives the sliding axle 2 to move through the cable joint I 31, so that the motorcycle front brake system works to realize the front and rear wheel linkage brake.

[0038] When performing combined braking, pressing the motorcycle's brake pedal activates the rear wheel brake, simultaneously pulling the rear brake system cable backward. This movement causes the sliding shaft 2 to move within the groove 11. The sliding shaft 2, in turn, pulls the cable connector I 31, driving the sliding shaft 2 to move. This movement pulls the cable on the front wheel brake, thus engaging the front wheel brake and achieving coordinated braking of both front and rear wheels.
