Abstract
A slack adjuster for a rail vehicle brake system, comprising a brake force receiving adjuster tube (1, 1A), a spindle (4; 4A) axially movable therein, and two nuts, an adjuster nut (5; 5A) and a leader nut (6; 6A), which are in non-self-locking thread engagement with the spindle and are held resiliently in clutch engagement with a clutch ring (7; 7A) and a control sleeve (16; 16A) respectively, the latter being axially movable in the tube a distance (A) corresponding to the desired slack. In order to transform this so called stroke-sensing adjuster into the so called clearance-sensing type being independent of the elasticity part of the application stroke the adjuster nut (5; 5A) and the clutch ring (7; 7A) in coaction are arranged to submit a force to the leader nut (6; 6A) for locking the latter against rotation under deformation of a resilient element (13; 30; 34; 38; 5A) at the occurrence of a counter-force on the spindle (4; 4A) during the brake application.
