<p>PURPOSE:To eliminate working moments on body and axle load movements between trucks so as to prevent lowering of adhesion by equalizing heights of a coupler and a center bearing for connecting a body with a truck measured from rail surface. CONSTITUTION:A body 1 is connected with a truck 12 by a center bearing 13 whereon weight of the body 1 is solely loaded. Bell cranks 21a, 21b are rotatably pivoted on vertical pins 22a, 22b in corners on one diagonal under the truck 12 so that one arm of each of the bell cranks extends at nearly right angle to both sides of the body 1 respectively, while the other arm thereof extends in almost parallel with the center line of the body 1. Further, one end of each of links 23a, 23b of equal length is rotatably connected to a tip end of one arm of each of both the bell cranks 21a, 21b, while the other ends are rotatably connected to both sides under the floor of the body 1 and tip ends of the other arms of both the bell cranks are rotatably connected to both ends of a link 24 horizontally arranged under the truck 12 so that both the cranks 23a, 23b spread out in the longitudinal direction of the body 1.</p> |
