TRACK-BELT FOR TRACK DRIVEN VEHICLES

摘要

The invention relates to an improvement in an endless track belt of the type comprising, a body made of an elastomeric material, an outer surface for contact with the ground and an inner surface provided with lugs or openings for engagement with the driving system and at least one endless pathway having a sliding surface contacting a corresponding slide rail of a slide rail suspension. This pathway is devoid of the lugs or openings for engagement with the driving system. The endless sliding surface is provided with a plurality of slide clips that are spaced apart from each other by a segment of the endless sliding surface. This segment is divided in at least a first and a second distinct part. The first part is made of elastomeric material and the second part defines at least one cavity through the body. The improvement is characterized in that the cavity through the body is to allow the introduction of snow between the slide rail and the first part and in that the first part is of such size that friction with the slide rail will generate heat in a sufficient amount to melt the snow and maintain a lubricating film of water therebetween. Such track belts are of a reduced weight but as efficient as common track belts.
