Art and Science of Braking Heavy Duty Vehicles 640795

The paper describes the functional relationship of the components making up shoe-drum type brake systems for heavy duty on-highway commerical vehicles. Analysis of torque-time traces is believed to be an aid in understanding what takes place at the lining-drum interface.
A contrast between theory and practice is emphasized by discussing vehicle and laboratory testing, the usage of commercial vehicles, and the empiric nature of friction. A hypothetical vehicle is used to illustrate brake engineering practice, but is restricted to load-torque balance and does not concern brake size selection.
