  • Brake monitoring system
    Patent number: 6501375
    Abstract: A brake monitoring system generally includes a plurality of brake monitors mounted on each of a plurality of brake actuators. Each brake monitor generally comprises a sleeve mounted to a push rod which moves relative to a stone shield on the brake actuator. The displacement of the sleeve relative to the stone shield is measured to determine the stroke of the brake actuator. This information is sent via an RF transmitter to a controller which determines the condition of each of the brakes.
    Type: Grant
    Filed: November 30, 1998
    Date of Patent: December 31, 2002
    Assignee: Indian Head Industries, Inc.
    Inventors: Bob R. Weant, Alan C. Lesesky, Graydon Choinski, Richard Rink, Henry T. Dangson

  • Brake actuator with centering dome in service chamber
    Patent number: 5588348
    Abstract: An improved spring brake actuator includes a dome extending into the service chamber from the center housing. The spring chamber push rod is formed with a plate having a cross-section corresponding to the dome. The service chamber diaphragm as well as the service chamber piston are also formed with surfaces that correspond to the shape of the dome. The surfaces "stack up" to ensure alignment between the spring chamber push rod and the service chamber push rod. The use of the dome also provides additional stroke to the spring chamber push rod without requiring additional axial length for the overall brake actuator.
