In this research, a new adaptive wedge disc brake mechanism is designed and constructed in order to investigate the behaviour of the braking force using brake dynamometer. The effect of water spray on the braking force is tested under different wedge inclination angles. The experimental results showed that the braking force generally fluctuates as a function of braking time due to the friction coefficient. The water spray has a significant effect on reducing the braking force between pad/disc compared with dry conditions. Reduction in wedge inclination angle increases the self-amplification action leading to an increase of the braking force.

Abstract


In this research, a new adaptive wedge disc brake mechanism is designed and constructed in order to investigate the behaviour of the braking force using brake dynamometer. The effect of water spray on the braking force is tested under different wedge inclination angles. The experimental results showed that the braking force generally fluctuates as a function of braking time due to the friction coefficient. The water spray has a significant effect on reducing the braking force between pad/disc compared with dry conditions. Reduction in wedge inclination angle increases the self-amplification action leading to an increase of the braking force.
