FIELD: machine building.
SUBSTANCE: invention relates to railway transport, particularly, to parking brakes of railway rolling stock. Brake comprises a "screw-nut" pair with self-braking thread, a rotor of the screw rotation and a device for transfer from the "screw-nut" pair of the pressing force to the friction elements of the brake. Device is flexible for drawing by axial force of the "screw-nut" pair so that at the stage of the brake elastic tightening the required value of pressing forces on the friction elements of the brake is achieved not less than three complete rotations of the screw relative to the nut.
EFFECT: stability of brake operation is achieved at action of vibration of path and other dynamic factors on braked object.
