Comparison of Different Variable Braking Force Systems 2018-01-1865
An automobile braking system has a crucial role in the safety of the passengers and riding quality of the vehicle. The braking force mainly depends on the normal reaction on the wheel and the coefficient of adhesion between the tire and the road surface. The required braking force for a vehicle varies with the load on the vehicle. If the applied braking force is greater than the required brake force, wheel gets locked which results in increased stopping distance. In order to prevent the wheel lock at low load conditions or deficient braking force at extremely high load conditions, a variable braking force system is developed. Whenever a motorcycle is loaded, the normal reaction on the rear wheel is increased. Thus, the amount of braking force required to halt the motorcycle with minimum stopping distance and stability of the motorcycle is based on the pillion load on the motorcycle. Hence, the amount of braking force developed between the road surface and the tire is varied in the variable braking force system. In this research work, three different variable brake force systems are compared. The different braking force systems are obtained by varying the effective disc radius or varying the pedal leverage or varying the area of piston. Simulation on the vehicle stopping distance is performed to compare the stopping distance of conventional braking system to Variable braking force system.
