Abstract

The invention discloses a bicycle high-speed disc brake system based on harmonic drive. The system comprises wheels, a driving shaft and a brake disc, the brake disc is fixed on the driving shaft, andthe driving shaft is connected with a centrifugal device. When the wheels rotate at a high speed, the driving shaft is driven to rotate together, and a centrifugal block can move outwards to match agroove in a cam shaft; when a brake cable is tensioned, the disc rotates to drive a lead screw to rotate, a nut block pushes a harmonic reducer to move forwards, a brake pad at the bottom of a flexible gear makes contact with the brake disc, the brake disc bears pressure of the brake pad and has torque opposite to the rotating direction, braking can be better achieved at the moment, and the torqueis reduced along with decreasing of the vehicle speed, so that the brake is not in a locked state; when the brake cable is loosened, the disc rotates under the action of a torsion spring and returnsto the initial position. By the adoption of the harmonic reducer brake device, when the wheels rotate at a high speed, the brake pad makes contact with the brake disc in a larger area, and the brakingeffect can be better achieved.

Description

technical field [0001] The patent of the invention belongs to the field of bicycle devices, in particular to a high-speed disc brake system for bicycles based on harmonic transmission. Background technique [0002] The traditional mechanical disc brake system achieves braking by controlling the strength of the hand brake. Over time, it will affect the sensitivity of the hand brake brake line and affect the braking effect. When the wheels are traveling at high speed, it is prone to danger. The present invention can better realize the braking effect according to the vehicle speed condition. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-speed disc brake system for bicycles based on harmonic transmission, which adopts the following technical solutions: [0004] A high-speed disc brake system for bicycles based on harmonic transmission includes: wheels, a drive shaft and a brake disc, the brake disc is fixed...
