AUTOMATIC COUPLING ASSEMBLY, METHOD AND DEVICE OF ITS PRODUCTION Russian patent published in 2010 - IPC B61G1/02 B61G7/10 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly to design of centre girder. Proposed assembly comprises front and rear cast thrusts with support surfaces and transition elements jointed together by plates. Said plates are made from rolled unequal channel angles. Large flange of every plate has a hole running along the entire length of plate. Said plates are made from material with strength properties equal to or exceeding those of said thrusts. Proposed method comprises assembling said plates with front and rear thrusts with support surfaces and transition elements. Said front and rear thrusts and plates are fitted into automatic coupling to be welded together therein along outer and inner edges. Proposed device comprises two sections simulating central girder cantilever part and revolving about lengthwise axis. Outer welded seams of joint between plates and transition elements have holes.

EFFECT: automatic coupling assembly design that increases central girder life and strength, ease of jointing thrusts together.
