FIELD: railway transport.
SUBSTANCE: proposed mechanical lock of brake cylinder rod contains brake cylinder rod with cylindrical insert with wedge-like cutout in zone where insert engages with pressure strips to prevent slipping of brake cylinder rod I fixed position. Stop clamping device is made in from of two clamps of self-braking multistep drives-motion converters to prevent separation of clamp under action of elastic forces of brake leverage and release spring of piston of brake cylinder in fixed position. To realize maximum possible force of clamps, their longitudinal axes are arranged square to spaces of wedge-like cutouts of insert and at acute angle to longitudinal axis of rod. Pneumatic drive is made in from of two individual double-acting pneumatic cylinders with possibility of use of air from main line of brake cylinder at braking for additional, drive apart from cylinder spring to provide clamp of rod of brake cylinder in brake-applied position and it is designed for fitting mechanical lock of brake cylinder rod onto brake cylinders of any type cars and locomotives.
EFFECT: improved fixing of brake cylinder rod.
