Definitions

  • the brake actuator can preferably further comprise a plug disposed in an end of the service brake actuator rod.
  • the spring brake actuator rod preferably extends into the service brake actuator rod far enough to abut the plug and urge the service brake actuator to engage the brake when the second spring brake chamber is evacuated.
  • the opening in the service brake actuator rod is preferably located adjacent the second movable member.
  • At least one weep hole is preferably disposed in each end of the spring brake actuator rod whereby the at least one weep hole in each end of the spring brake actuator rod fluidly connects the interior of the service brake actuator rod with the first spring brake chamber.
  • a caging rod is preferably mounted at a first end to the spring brake actuator housing and extending within the spring brake actuator rod.
  • a second end of the caging rod preferably has a plate thereon.
  • the plate on the second end of the caging rod preferably has at least one passage extending through it.
  • the at least one passage in the plate is preferably disposed inwardly from a peripheral edge of the plate.
  • the fluid then exits the proximal end 86 of the actuator rod 84 and into the second spring brake chamber 78 through the weep holes 102.
  • the fluid exits the second spring brake chamber 78 through the weep holes 100 in the annular recess 98 and into the filter assembly 134.

Abstract

Un actionneur de frein à ressort (10), pourvu d'un ressort de compression puissant (82) dans une deuxième chambre de ressort (78) du carter, comporte des évents (100) dans le carter communiquant avec la deuxième chambre de ressort (78). Un ensemble filtrant (134) recouvre les évents (100). Des trous d'évacuation (62), (104), (102) et (100) ménagés dans un manchon (50) d'une tige de poussée (18), dans une tige d'actionneur de frein à ressort (4), et dans une portion (68) du carter de frein à ressort permettent conjointement au fluide comprimé dans une première chambre de frein de service (30) de s'écouler, par l'intermédiaire d'un conduit défini par ces trous d'évacuation, hors de l'actionneur de frein (10) dans lequel il est filtré par l'ensemble filtrant (134).
