FIELD: mechanic.

SUBSTANCE: axle stopper is equipped with a key for opening of the locking mechanism and contains shell, drum, and detent. The shell and the drum are provided with pins placed coaxially along the circle and the axis forming a locking mechanism. The drum is placed in the shell with the possibility of rotating about its axis. The detent is rigidly mounted in the shell. Cuts for the axle being locked are made in the detent and in the drum. A central cylindrical hole is made in the drum, into which a sprung stepped piston is installed, interacting with pins of the end and cylindrical parts. Each pin consists of three parts, as a minimum. One part is stepped, interacting with the key, the other part is compound consisting of cylinder and rod with the possibility of fixed length changing, and the last part is cylindrical, interacting with the piston. The last part of the pins is stepped, except for one pin, which is cylindrical. The stepped pins are installed with the smaller diameter in the drum and bigger diameter in the shell. The part of the stepped pin with the smaller pin diameter is placed both in the shell and in the drum.

EFFECT: excludes possibility of unauthorised unlocking of axle stopper.
