A track-laying vehicle has a frame with a pair of opposite sides, a track suspension on each side of the frame, and respective vibration-damping support bodies fixed on the suspensions and on the frame and securing the suspensions to the frame. Each suspension has a support housing movable relative to the side, road wheels journaled on the housing, a drive wheel journaled on the housing, and a track spanned over the respective wheels. In accordance with this invention a brace strut extending crosswise across the frame between the sides thereof has outer ends connected to the respective suspension housings. The strut can extend underneath the frame so that the forces caused by upward pressure of the ground on the ground wheels that tend to push out the bottoms of the suspension housings cancel each other out. The strut can also extend horizontally between the frames ahead of the front wall and another such strut can extend horizontally between the frames behind the back wall. These front and back struts cancel out the forces caused by tension in the belt that push out the front and back ends of the suspension housing.
