Abstract
A railway vehicle truck including side frames and wheel sets maintained in a substantially rectangular relationship by resilient connection means at each of the axle mounts to the side frames. The resilient means are prestressed and in equilibrium at each mounting location so as to resist yaw and lengthwise movement of the axles relative to the side frames. The resilient means provide resistance to hunting motion and yet yieldingly permit relative turning of the axle and side frame when the truck traverses a curved track.
