Abstract: Disclosed is a method and device for determining potential damage of an endless track of a tracked vehicle. Said vehicle comprises at least one track assembly comprising a drive wheel member, a tension wheel member, a set of road wheels and said endless track disposed around said wheels. Said endless track is rotated by means of said drive wheel member during drive. The method comprises the steps of: receiving, from at least one sensor, measurement information associated with vibrations of said endless track; based on the information received from said at least one sensor, determining if there is a natural frequency of said endless track and if so determining the natural frequency of said endless track; and, based on the determination associated with natural frequency, determining whether there is a potential damage to the endless track.

Abstract: The object of the present invention is to provide a rubber crawler having high traction force and excellent straight-ahead driving property and further improved durability by ensuring good soil-grasping property and soil-discharging property of the crawler body. The rubber crawler 1 has a crawler body 10 and a plurality of metal cores 30 buried in the crawler body and lugs 13 provided on an outer periphery side with they being divided into left and right sides across the central portion, the lugs divided into left and right sides being arranged in zigzag alignment with shifting of phase in a circumferential direction of the crawler body, wherein a contact area of the each lug 13 is divided into a central lug portion 20 and an outer lug portion 22. During running of the rubber crawler, the central lug portion 20 and the outer lug portion 23 of each of the lugs 13 connect to ground, and therefore, a force supporting the metal cores 30 are sufficiently ensured by the lugs to suppresses peeling of the crawler body from the metal cores or crack of the crawler body, which brings about enhancement of durability of the crawler body 10. Meanwhile, excellent soil-grasping property and soil-discharging property are maintained without destroying mud grasped by the groove 18 extending in the circumference direction, which brings about enhancement of straight-ahead driving property and suppresses occurrence of side slipping on a soft ground or a slope ground.

Abstract translation: 本发明的目的是提供一种具有高牵引力和优异的直行驱动性能的橡胶履带，并且通过确保履带主体的良好的抓地性和污物排放性能来进一步提高耐久性。 橡胶履带1具有履带体10和埋在履带体中的多个金属芯30和设置在外周侧的凸耳13，它们分隔成横跨中心部分的左右两侧，凸耳分为左和 右侧以履带主体的圆周方向的相位移动而以锯齿形排列布置，其中每个凸耳13的接触区域分成中心凸耳部分20和外凸耳部分22.在橡胶履带运行期间 每个凸耳13的中心凸耳部分20和外凸耳部分23连接到地面上，因此，凸耳足以确保支撑金属芯30的力，以抑制履带体从金属芯的剥离或 履带主体的裂缝，这增加了履带体10的耐久性。同时，保持优良的抓地性和排污性能，而不破坏泥浆抓地力 通过沿圆周方向延伸的槽18，这促进了直线驱动性能的提高，并且抑制了在软地面或斜坡地面上的侧滑的发生。
