Design and Analysis of a Novel Centrifugal Braking Device for a Mechanical Antilock Braking System

Abstract

A new concept for a mechanical antilock braking system (ABS) with a centrifugal braking device (CBD), termed a centrifugal ABS (CABS), is presented and developed in this paper. This new CBD functions as a brake in which the output braking torque adjusts itself depending on the speed of the output rotation. First, the structure and mechanical models of the entire braking system are introduced and established. Second, a numerical computer program for simulating the operation of the system is developed. The characteristics of the system can be easily identified and can be designed with better performance by using this program to studying the effects of different design parameters. Finally, the difference in the braking performance between the CABS and the braking system with or without a traditional ABS is discussed. The simulation results indicate that the CABS can prevent the wheel from locking even if excessive operating force is provided while still maintaining acceptable braking performance.
