Abstract
The utility model relates to a mechanical disc brake. At least one of the two friction plates in a disc brake clamp body is provided with a follow-up mechanism which is a follow-up bevel arranged on the backside of the friction plate; the follow-up lift angle alpha of the follow-up bevel ranges 0 to 20 DEG. A component connected to the backside of the friction plate is provided with a fixed bevel matching with the follow-up bevel. Once users hold the brake, before the friction plate contacts with the disc brake disk to a locking state, a frictional force along the tangential direction of the disc brake disk is generated between the friction plate and disc brake disk; driven by the frictional force, the friction plate swings along the follow-up bevel; affected by the follow-up lift angle, the travel range of the friction plate is correspondingly increased, and therefore, the brake force is increased by fold. Thus, the mechanical disc brake can wedge tightly the disc disk like a wedge to realize the braking; the higher the running speed is the bigger the brake force is and the better the braking effect is. The mechanical disc brake makes use of the follow-up theory, generates a follow-up force through the frictional force between the friction plate and the disc brake sheet, and consequently enlargethe braking force. As long as users gently move a crank, they can get an ideal braking effect.
