ABSTRACT:
A rail vehicle slack adjuster of the double-acting, clearance-sensing, axial type has an elongated barrel (4), a pull means (6, 48), a non-rotatable spindle (2), a leader unit (8-27) and an adjuster unit (29-52) cooperating with the spindle in the barrel, and a barrel spring (53) acting on the adjuster unit. A leader nut (8) in the leader unit can be clutched (13-16) to the barrel under the action of a pay-out spring (21). An adjuster nut (29) in the adjuster unit can be clutched to the pull means.
The adjuster unit (29-52) includes a non-rotatable spline sleeve (40) acted on by the pulling brake force from the pull means (6, 48) and the opposite force from the barrel spring (53). The leader nut (8) is provided with a telescope sleeve (11) and a leader ring (27), both only axially movable on the leader nut and being clutchable to the spline sleeve. The leader nut is also provided with declutching means (13-15) enabling the nut to rotate in spite of the clutch engagement (16) with the barrel (4).
