摘要： An anti-skid device for installation on a belt of a crawler vehicle or wheel of a wheel drive includes a base body which, along a direction which corresponds to the running direction of the crawler belt or wheel, has at least two bottom sections (which, in the installed state, rest on a running surface of the belt or wheel, and has at least one rib section which is curved upward and is arranged between two bottom parts. One or more fastening points are provided in the bottom sections for anchoring the anti-skid device to the belt. The rib section is supported on the bottom sections and is divided into two or more rib parts in the direction transverse to the running direction; in addition, recesses are provided in lateral flanks of the rib section. One or more traction elements that project away can be provided on the rib parts.

摘要： A chisel nut for use in improving traction of a ground engaging drive element of a vehicle includes a body having a first end for engaging the ground engaging drive element and a second end disposed opposite the first end. A chisel face is defined on a side of the body spaced a distance from the first end and extending to an edge at the second end of the body. The chisel face sized and configured to extend outward from the ground engaging drive element beyond lug members of the ground engaging drive element. A hole is defined in the body about a longitudinal axis and extends from an opening at the first end of the body toward the second end of the body. The hole includes a threaded portion for threadingly engaging with a threaded portion of a cooperatively sized fastener positioned in the hole.

摘要： A chain system is provided that is attached to a continuous track of a tracked vehicle. Embodiments of the chain system can include cross chains that extend from a side chain, and a hook is disposed at a free end of each cross chain. To attach the chain system to the track, the hooks are attached to an inner edge of the track on a top surface of the track. Once all of the hooks are attached, the ends of the side chain are attached to each other and the chain is secured to the track to improve the traction of the track and the tracked vehicle.

摘要： The present invention relates to a running gear chain (2), in particular a bogie chain (2), having a flexible body (20), preferably an elastomer body (20), which is closed in endless fashion, or closable in endless fashion, in a running direction (A). The running gear chain (2) according to the invention is characterized by a multiplicity of rigid transverse elements (24) which are connected to the outer side of the flexible body (20) and extend substantially transversely with respect to the running direction (A), wherein at least some of the rigid transverse elements (24), preferably all of the rigid transverse elements (24), are arranged so close together in the running direction (A) that, with a planar extent of the flexible body (20), two immediately adjacent rigid transverse elements (24) make contact in the running direction (A).

摘要： A track shoe for an endless track assembly has a base and an opposing hull. The hull of the track shoe has opposing sidewalls that are angled to meet at an apex, thus forming an inverted V-shape. The apex of the hull extends the width of the track shoe. Laterally-disposed ridges are spaced apart from the apex. and the height of the ridges tapers outwardly from the hull to form, respectively, a leading lip and a trailing lip of the track shoe. The track shoe may have upward bends at the ends of the width of the track shoe and optionally, may have secondary hulls.
