Abstract

um ajustador de folga tendo um alojamento único, unitário que muda de comprimento para compensar o desgaste do amortecedor de freio em um sistema de frenagem em um vagão ferroviário. uma haste de tensão rosqueada estende um comprimento variável a partir do alojamento dependendo da rotação da haste de tensão em relação ao alojamento. uma montagem de embreagem encerrada dentro de uma guia de haste controla a rotação da haste de tensão e uma montagem de sobrecurso posicionada no alojamento único controla se a montagem de embreagem permitirá ou impedirá a rotação da haste rosqueada. uma haste de controle e o tubo de atuação transmitem as forças de controle à montagem de sobrecurso de modo que a haste de tensão será retida em um novo comprimento quando o ajustador de folga precisar absorver uma folga no sistema de frenagem.a slack adjuster having a single, unitary housing that changes in length to compensate for brake damper wear in a braking system on a rail car. a threaded tension rod extends a variable length from the housing depending on the rotation of the tension rod relative to the housing. a clutch assembly enclosed within a stem guide controls the tension rod rotation and an overtravel assembly positioned in the single housing controls whether the clutch assembly will allow or prevent rotation of the threaded stem. A control rod and actuation tube transmit control forces to the overcurrent assembly so that the tension rod will be retained to a new length when the slack adjuster needs to absorb a slack in the braking system.
