FIELD: transport engineering; rail vehicles. ^ SUBSTANCE: invention relates for setting wheelsets 1 of locomotive bogie for negotiating curved sections of track. Proposed device contains two vertical posts 2 with two arms installed for turning on bogie frame, cross tie-rod 3 and two axle-box links 4, control unit 4 with plan of track section and motion sensor of locomotive 7. Cross-rod consists of three articulated members. Each end of cross rod is hinge-coupled with first arm 9 of corresponding vertical post. Middle member 12 of cross rod is provided with self-braking reversible drive 5 installed on frame of bogie and made for translational movement in transient curve of middle member of cross rod along its longitudinal axis and provision of moving force found from mathematical formula depending on parameters of bogie and rail gauge. Each axle-box link is connected by one end with corresponding axle box of bogie wheelset, and by other end, with second arm 10 of corresponding vertical post. Control unit is electrically coupled with drive and locomotive motion sensor. ^ EFFECT: reduced pressure force on rail exposed by wheels flange on transient curves and exclusion of this force in circular curves. ^ 1 tbl, 1 dwg |
