摘要： In one aspect of the present invention is provided an attachment device (100) for attachment of a trailing arm (54a) to a track support beam (22) intended to be connected, via said trailing arm (54a), to a center beam (30, 32) or other structural element situated between two track assemblies (21) of a tracked vehicle (10). The attachment device (100) is secured to the track support beam (22) and configured to attach the trailing arm (54a) to the track support beam (22) via an axis (X2) running above and substantially centrally along an upper side of the track support beam (22), in the longitudinal direction of the track support beam. In this way, a robust, structurally strong, suspension-admitting attachment device that is easy to manufacture and assemble is achieved. In another aspect of the invention is provided a tracked vehicle (10) comprising such an attachment device (100) and in a further aspect of the invention a method of manufacturing a track support beam (22) comprising such an attachment device (100).
