Abstract
The present invention provides a bicycle brake performance test system. The system comprises a test table, a fixed support, a spray and air blast system and a hand brake motion mechanism which are arranged at the upper portion of the test table, a front-wheel lever-type weight bearing system, a roller and a rear-wheel lever-type weight bearing system. The fixed support is composed of a front support and a rear support and is configured to fix the front and rear wheel of the bicycle; the hand brake motion mechanism is arranged at the upper portion of the brake on the bicycle and is configured to drive the brake motion; a front-brake power sensor is arranged on the position of the front support opposite to the surface of the wheel tire, and a back-brake power sensor is arranged on the position of the rear support opposite to the surface of the wheel tire to measure the motion and the stopping of the tire. The test table employs a dual-roller mode, the test of the braking force of the front and back brakes may be completed only by clamping once, and therefore the problem of low efficiency of the single-roller mode is avoided.

The available content of the test of the invention mainly has following several:
1. hold lock power/brake force to measure (see standard P27, clause 4.6.8.5.3 testing machine test side
Method)
By standard-required, holding lock power needs with 20N as increment, progressively increases to 180N from 40N, respectively
Measure the corresponding brake force that front/rear lock produces under difference holds lock power.Meanwhile, standard also requires to survey respectively
Go out the brake force that bicycle is the most corresponding under dry state with hygrometric state (spraying wheel).
During dry state test, by bicycle clamping on test platform, by lever loading system on wheel
Apply enough to prevent the downward vertical force of wheel-slip, cylinder from starting to roll, when reaching standard-required
During rotating speed (linear resonance surface velocity 12.5m/s), PID the parking brake actuating mechanism controlled is (front to left and right respectively
What afterwards) parking brake generation required holds lock power, front/rear braking force transducer determine the system now produced
Power.
Hygrometric state method of testing ibid, but needs to test under wheel is by the spray state of standard-required.
2. brake heat resistant test (see standard P33, clause 4.6.9 brake heat resistant test)
Clamping bicycle on test platform is driven with the speed of 12.5km/h ± 5% and holds lock, simultaneously
The cold air having a speed to be 12.5km/h to after-blow brake block, the total braking energy so produced is
55Wh.Test should continue 15min.
3. (see standard P75, appendix C assembling is perfect voluntarily in whole bicycle structural strength fatigue test
Bassinet structure robustness)
By a perfect bicycle clamping of assembling on testing machine, respectively saddle pipe, crank, transverse tube
And on clothes hanger, place the pouring weight of standard-required；The cylinder of testing machine presses standard-required equipped with batten.
Rotate cylinder to make to reach linear resonance surface velocity to be 8km/h, test 6 hours.
4. tire/wheel molectron fatigue test (see standard P77, Appendix D tire/wheel parts-
Fatigue test)
By tire/wheel molectron clamping above cylinder, by lever to weight system, it is applied
Load vertically downward；The cylinder of testing machine presses standard-required equipped with metal link stopper.
Rotating cylinder and reaching linear resonance surface velocity is 25km/h, makes to reach between tire and metal backup
The shock number of times that standard specifies.
The foregoing is only the preferred embodiment of the invention, not in order to limit present invention wound
Make, within all spirit in the invention and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in the protection domain of the invention.
