Between the first pull rod, the second pull rod, the first pull rod, the second pull rod at middle part in X-type cross and being hinged；The both ends of first pull rod
Hinged with one end of the first damper, the second damper respectively, the both ends of the second pull rod are damped with the first damper, second respectively
The other end of device is hinged, and two hinged ends of homonymy form longitudinally movable connection with left rail beam, right rail beam respectively.
The invention has the advantages that by damper original mutual independent left rail beam, right rail beam
An entirety is connected into, the lateral stiffness of track structure is increased so that the lateral aerostatic instability sex chromosome mosaicism of structure obtains effectively
It solves, while lateral displacement of the structure under beam wind effect can be reduced, ensure traffic safety；Increase the antitorque rigid of structure
Degree improves the performance that structure resists galloping, meanwhile, in camber beam location the torsional deflection of structure is effectively reduced, ensures
Road-ability and traffic safety；Structural damping ratio is increased, effectively inhibits structural vibration caused by a variety of causes, ensure that row
Vehicle comfort and traffic safety.
