SLACK ADJUSTER FOR A RAIL VEHICLE BRAKE SYSTEM

摘要

A slack adjuster of the so called one-nut type for a rail vehicle brake system includes an adjuster tube, a spindle, a nut in non-self-locking thread engagement therewith, two opposite clutch surfaces on the nut cooperating with corresponding clutch surfaces on the tube, and a barrel spring. The nut is provided with a thrust bearing resiliently held forward against a nut projection. A control means (preferably in the form of a sleeve flange) is situated in front of the bearing in the rest position at a distance corresponding to the desired slack.
