Generalizing the Analysis of Shoe-Type Brake-Clutch Systems

Abstract

The equations used in the analysis of asymmetrically pivoted shoe-type brake-clutch systems are derived. The equations include the pressure function, average pressure, torque, energizing effect, and parameters for locating the resultant force center. These equations are shown to be valid also in the analysis of both symmetrically pivoted and “floating” shoe type systems as well as short shoe systems, thus providing the designer with one set of equations that can be used for these common types of shoes used in brake-clutch systems. A table summarizing derived equations is given and typical graphical representations of relationships are shown.
