FIELD: railway transport. ^ SUBSTANCE: invention relates to automatic couplers of long-base four-axle freight cars. Proposed device contains automatic coupler hinge-mounted on center sill of car frame and resting on center sill through centering bar of alignment mechanism, and automatic coupler and bogie turn matching mechanism containing U-shaped torsion bar hinge-secured by its horizontal part on center sill. Ends of torsion bar are pointed downwards, one end being connected with centering bar by means of horizontal hinge joint and end face bracket. Matching mechanism is provided with rocket hinge-connected from below on axle of center sill by means of vertical bracket. Longitudinal arm of rocker is hinge-connected though rod and horizontal joint with second end of U-shaped torsion bar. It has link made in form of screw pair whose stationary part is hinge-connected with cross arm of rocket and turnable part is furnished with axial turn angle limiter and is connected with cross spring beam of bogie by means of fastening unit which is made detachable in form of grip whose turning member is made in form of base with threaded stud provided with support part and eye on end for fastening the link. Longitudinal turning axis of turnable member lies in one horizontal plane with axis of link. Grip is provided with retainer with thread mechanically coupled with base, twin cone stop hinge-secured on retainer for turning in longitudinal plane of grip and engagement of conical surfaces with inner angular edge of dummy hole in spring beam, and thrust plate installed for movement on threaded stud between support part of base and retainer for interaction with outer plane of side wall of spring beam near dummy hole. Axial turn angle limiter of turnable part of link is made in form of form secured on its end for engagement with plane of cross arm of rocker. ^ EFFECT: provision of reliable coupling of automatic coupler of four-axle long-base cars of curvilinear sections of tracks. ^ 2 cl, 6 dwg
