The invention provides a brake device, a brake device and a bicycle, the brake device comprises a brake control assembly, a brake fine adjustment assembly and a shoe block assembly, the brake fine adjustment assembly comprises a ratchet wheel part and a pawl part, and the pawl part is clamped on the ratchet wheel part; the brake control assembly has a first moving range and a second moving range; when the brake control assembly moves in the first moving range, the brake control assembly drives the shoe block assembly to brake; when the brake control assembly moves to a second moving range due to abrasion of the shoe block assembly, the brake control assembly drives the ratchet part to move, and the clamping position of the pawl part on the ratchet part is changed; the ratchet wheel part is used for driving the shoe block assembly to move so as to adjust the initial position of the shoe block assembly during braking, and therefore a good braking effect can be achieved when the shoe block assembly is abraded.
本发明提供一种刹车装置、制动装置及自行车,刹车装置包括制动操纵组件、制动微调组件以及蹄块组件,制动微调组件包括棘轮件和棘爪件,棘爪件卡合在棘轮件上;所制动操纵组件具有第一移动范围和第二移动范围;制动操纵组件在第一移动范围内移动时,制动操纵组件驱动蹄块组件进行刹车;蹄块组件磨损导致制动操纵组件移动至第二移动范围时,制动操纵组件驱动棘轮件移动,且棘爪件在棘轮件上的卡合位置发生变化;棘轮件用于驱动蹄块组件移动,以调节蹄块组件刹车时的初始位置,从而在蹄块组件磨损时也可以实现良好的刹车效果。
