Abstract

The testing machine includes mechanism for mounting and clipping bicycle to be fixed, mechanism for applying force on brake, device for measuring torque, cylinder for applying force, and electric control unit. The mechanism for applying force on brake is connected to brakes. Device for measuring torque includes a driving motor and friction roller, which is connected to the output shaft of the driving motor. The friction roller is under wheel of bicycle mounted and clipped on the mounting and clipping mechanism. Torsion sensor is installed on the shaft of the motor. Device for measuring torque is connected to piston rod of cylinder for applying force fixedly. Being connected to output end of revolution speed sensor and control wire of drive set of cylinder for applying force, the electric control unit keeps revolution speed at rated value of speed. Advantages are: automatic operation and accurate result tested.

Description

(1) Technical field [0001] The invention relates to detection equipment for bicycle braking performance testing. (2) Background technology [0002] Braking performance is an important functional test item in bicycle testing. The current national standards GB14746 "Safety Requirements for Children's Bicycles" and GB3565 "Safety Requirements for Bicycles" respectively stipulate the braking performance and the linearity of the foot brake. Use a cloth belt to pull the wheel in the tangential direction of the wheel. One end of the tension gauge is connected to the cloth belt, and the other end is manually pulled by the tester. The braking force on the brake is provided by adding weights. According to the standard, for each braking force applied, three braking forces must be measured and averaged. And each brake must apply five different braking forces. In this way, 15 braking forces must be measured for each brake test to obtain an actual brake force and braking force curve, a...
