FIELD: rail vehicles.

SUBSTANCE: disclosed is a rigid coupling device with a universal trailing shank for railroad cars, consisting of two couplers and two centring devices, wherein housing of each hitch consists of head and trailing shank, interconnected by cylindrical hinge with horizontally located pivot pin, head of one of pins is equipped with coupling mechanisms, and head of the other is equipped with disengagement mechanism and guiding cone with its attachment parts, wherein in each hitch coupling body there is a vertically oriented hole for installation of a flat pin in it, which connects the coupler to the car harness. Shank shape and dimensions correspond to shape and size of tail part of automatic coupler CA-3, which provides rigid interlocking device interchangeability with automatic coupler CA-3.

EFFECT: application of the universal trailing shank makes it possible to quickly install the proposed rigid coupling device instead of automatic coupling CA-3 without replacement of the harness; besides, there is possibility of application of other rigid coupling devices, after their completion for installation of universal trailing shank.
