CHARACTERISTICS
- Reduce turn over
- Avoid slip in high-spaced turning
- Improveopcrational control and increase rider's comfort
- Absorb vibration and so no brake noise
- No harm to wheel rim
The sensitivity and strength of V-brake is averagely 180% of canti-brake.
Yet the difficulty of reducing speed for end-over-ends cause the sliding occusrs usually.
In order to over come such problems we research and develop ABS functional brake shoes.
THEORY OF ABS FUNCTIONAL BRAKE SHOE
- Two-step brake action, the fist step is reducing speed and momentum, the second step is brake action. Because the momentum has been reduced, the probability of trim-over lower down 47.11%
- Improve operational control of brake shoes to attain the effect of reducing speed. According to some research report which use 5 vehicles to test, O times, when the speed of vehicle over 10.5 km/hr and turning angle is 80, the probability of slip for sudden brake is 98%. The chart below illustrate the reason for slip.
For example, we ride a bicycle with a 15km/hr speed, when we are about to turn, we wish to reduce the speed to 5km/hr. Traditional brake shoes will usually stop the wheel totally, yet the remaining momentum will bring the speed back to 5km/hr. The vehicle will slip in the process when the speed reduce to O suddenly (at point O). However, ABS functional brake shoes with two-step action reduce such dangerous situation.
ANOTHER TEST
We do CPSC standard test with 5 vehicles and repeat 12 times. Testing condition:loading 68.1kgs, speed 24km/hr. Braking distance less than 4.57m
- indicate the lengths of no braking tracks
- indicate the length of sliding offer tyro being locked death
SUCCESS RATE |
|
| 23 times | 38.33% |
| 58 times | 96.67% |
CONCLUSION
- Traditional brake shoes when reducing speed will lock the type cause the vibration of the rear wheel, safety and stability is worse.
- ABS functional brake shoes will reduce the speed and momentum first, and then brake the vehicle, which will cause straight brake, safety is better.
