FIELD: machine engineering.
SUBSTANCE: air-controlled brake cylinder contains a body, a spring brake, a brake cylinder piston and an emergency releasing brake device. A spindle is designed to be screwed into a retractable, non-rotatable in the pipe brake cylinder piston with spring brake by means of a body closure of the nut. The body closure is formed on one hand, between passing in a circle on the outer periphery of the nut towards the periphery of outer polygon profile and further formed circular internal polygon profile on the inner periphery of the intermediate bushing, and, on the other hand, by passing in a circle on the outer periphery of the intermediate bushing in the direction of the outer periphery of the polygon profile and additionally formed a circular internal polygon profile on the inner periphery of the pipe of the brake cylinder piston with the spring brake.
EFFECT: increase the reliability of the brake cylinder.
