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).

Abstract: A brake adjuster mechanism is of the type operable by a piston moving a threaded spindle axially during braking with a threaded nut thereon adjusting the spindle position. Two control members movable with the spindle are held apart by a spring between shoulder stops on the nut and they serve to position the nut between two opposed clutch surfaces to permit nut rotation until a predetermined slack setting is achieved.
Abstract translation: 制动调节器机构的类型是可操作的，该活塞通过活塞在制动期间轴向移动螺纹主轴，螺母在其上调节主轴位置。 两个与主轴一起移动的控制部件通过螺母上的肩部止动件之间的弹簧保持分开，并且它们用于将螺母定位在两个相对的离合器表面之间，以允许螺母旋转，直到实现预定的松弛设置。

Abstract: Depicted and described is a floating caliper brake comprising an adjustment device, wherein when a second distance between a first end section and a second end section is equal to, or greater than, a predefined distance, an actuation section of an adjustment element engages with a gear section in such a way that an increase in the second distance of the actuation section of the adjustment element causes the gear section to rotate about a central axis relative to a second transmission section, in such a manner that the second transmission section moves away from the gear section along the axial direction.

Abstract: A drainage system for use with a slack adjuster for a railway brake rigging wherein the slack adjuster includes a main spring housing, a cone nut housing enclosing a critical operating area of the slack adjuster, and an over travel housing. The drainage system includes at least one opening extending through a sidewall portion of the main spring housing. The opening is configured to allow fluid and/or contaminates to drain therethrough to reduce exposure of the critical operating area of the slack adjuster to the fluid and/or contaminants. A seal/splash guard can be provided at the intersection of the main spring housing and the cone nut housing to prevent fluid and contaminants from entering into the cone nut housing.
