Abstract

A rapid-stop device for the control roller of an automatic weapon wherein for a space-saving arrangement, a brake unit forming part of the rapid-stop device is disposed in a longitudinally axial bore of the control roller. Within its jacket, the brake unit includes brake shims and pretensioned spring elements 79. The brake unit jacket is mounted on a central mandrel, which is fixed to the cradle housing, so as not to be displaceable in the axial direction, and is connected with the control roller so that it can rotate with same and so that the control roller can move axially relative to the jacket. For a braking process required in the case of malfunction or during normal shut-down of the automatic weapon, a trigger catch lever or a rapid-stop catch lever disposed in the housing engages in the sole catch edge of a brake disc which is coaxial with the support mandrel. At the same time, a control disc, which is drivingly connected for rotation with the control roller and which is normally connected with the brake disc in a forming locking manner by an axial displacement arrangement, displaces the brake disc, under the inertia of further rotating parts connected to the control disk, in the direction of the brake shims, and thus performs a safe and attenuated brake stroke.
