  • Expander for internal shoe drum brakes
    Patent number: 4260042
    Abstract: An expander for internal shoe drum brakes comprises involute working surfaces which are derived from mutually eccentric base circles of equal diameters. The base circles are symmetrically arranged with respect to the axis of rotation of the expander. Upon rotation of the expander the arms of the braking forces initially increase and then decrease whereby a constant relation between angular expander displacements and retarding torques can be obtained.
