FIELD: measurement technology.
SUBSTANCE: invention relates to control over technical condition of automatic coupling during current inspection of car. Central mark is applied on automatic coupler. A central mark and marks of maximum allowable head deviations are applied on the head part of automatic coupling. At current inspection of car checking integrity of wedge clamp, head exit speed of automatic coupler device from impact socket, presence of a gap between the absorbing device and a pull yoke and alignment of the central mark of the socket with marks on the head part. Car beyond permissible deviations of head part is directed for repair.
EFFECT: higher probability of automatic failure detection of automatic couplings without its dismantling.
