FIELD: railway transport.
SUBSTANCE: invention relates to design of link for axle boxes, frames and bodies of locomotives. Proposed link contains housing in form of coaxial inner and outer semihousing 2 and 1, respectively interconnected by one or several elastic members 7 arranged in ring space between semihousing, and hinge joints 4. Elastic members can be connected with semihousings through bushings 8. space between semihousing can be filled with liquid and it can accommodate piston 9 with valve 10 and hydraulic compensator 11 hinge-connected by rod 12 with one of semihousings. At least one of semihousings can be furnished with tensioner 13.
EFFECT: improved dynamic characteristics in motion of locomotive, increased damping of joints of wheelset with frame and body of locomotive, improved stability of movement of wheels at high speeds.
