FIELD: transportation.SUBSTANCE: group of inventions relates to railway transport, particularly, to coupling devices. Coupling device comprises rectangular design housing with outer walls. Walls inner surfaces form inner cavity. Housing comprises front part with edges, forming hole, and rear part. Housing additionally comprises two solid side supports, two central ribs and friction wedge. Supports pass from point, located approximately in middle between housing outer wall front and rear parts, to intersection point with rear part edge. Each central rib also passes from point located approximately in middle between housing outer wall front and rear parts, to intersection point with rear part. Friction wedge is located inside housing cavity. Friction wedge is characterized by presence of end extending from hole in housing front part. Friction wedge additionally contains pad located on wedge external surface. Friction wedge working element interacts with housing internal surfaces.EFFECT: enabling higher reliability of coupling.9 cl, 5 dwg |
