The invention discloses a brake disc capable of detecting abrasion of a brake pad of a bicycle and braking emergently. The brake disc comprises the brake disc, an axle contact disc, a rotating shaft and the brake pad, the brake pad is slidably connected with the brake disc, a control rod is fixedly connected to the inner side of the brake pad, and a first guide pipe is fixedly installed in the control rod; a first valve is fixedly installed on the outer side of the first guide pipe, an air chamber is fixedly installed at the upper end of the first guide pipe, and the lower end of the air chamber is in a protruding shape. According to the brake disc capable of detecting the abrasion of the brake pad of the bicycle and braking emergently, when the brake pad is seriously abraded, the moving distance of the brake pad is increased, so that the moving distance of the control rod is increased to open the first valve, meanwhile, a rotating shaft extrudes a protrusion of the air chamber when rotating, and air in the air chamber pushes a rotating wheel to rotate under extrusion force; and the rotating wheel stirs an elastic piece to shake and makes a sound to remind a user, and the effect of automatically reminding the user after the brake pad is abraded is achieved.

    本发明公开了一种自行车刹车片磨损检测并能紧急制动的刹车盘,包括刹车盘、车轴接触盘、转轴和刹车片,所述刹车片与刹车盘滑动连接,刹车片的内侧固定连接有控制杆,控制杆的内部固定安装有第一导管,第一导管的外侧固定安装有第一阀门,第一导管的上端固定安装有气室,且气室的下端呈凸起状。该自行车刹车片磨损检测并能紧急制动的刹车盘,通过刹车片磨损较为严重时,此时刹车片的移动距离增加,从而控制杆的移动距离增加将第一阀门打开,同时转轴转动时会挤压气室的凸起处,从而气室中的气体受到挤压力推动转轮转动,使得转轮拨动弹片晃动并发出响声提醒使用者,实现了刹车片磨损后自动对使用者进行提醒的效果。
