    • A crawler belt for use on a crawler motor vehicle has an elongate belt body drivable in a predetermined direction, and a plurality of ridges mounted on a ground contact side of the belt body, each of the ridges having at least one sipe defined in a free end thereof for allowing the ridge to be flexibly deformable in a direction opposite to the predetermined direction. Each of the ridges has a plurality of sipes defined therein and extending longitudinally thereof or substantially perpendicularly to the predetermined direction. The ridges comprise a plurality of chevron-shaped ridges pointing toward the predetermined direction and succesively arranged at predetermined spaced intervals in the predetermined direction. The ridges are divided into a plurality of groups each including a plurality of ridges by grooves extending transversely of the belt body, and divided into a plurality of segments by at least one longitudinal groove extending longitudinally of the belt body.
    • 用于履带式机动车辆的履带具有沿预定方向可驱动的细长带状体,以及安装在带体的接地接触侧的多个脊,每个脊具有限定为自由度的至少一个刀槽花纹 其端部允许脊沿与预定方向相反的方向可挠曲地变形。 每个脊具有限定在其中的多个刀槽花纹,并且纵向延伸或基本垂直于预定方向延伸。 脊部包括指向预定方向的多个人字形脊,并且沿预定方向以预定间隔的间隔连续布置。 脊被分成多个组,每个组包括多个脊,通过沿着带主体横向延伸的槽,并且通过至少一个沿着带主体纵向延伸的纵向槽分成多个段。

    • Disclosed is a soft and flexible thermoplastic resinous composition having high impact and tear resistances, a good processability and a good thermal adhesion to a wide variety of plastic and other materials. The resinous composition consists essentially of 5 to 70 wt. % of a thermoplastic polyurethane elastomer and 30 to 95 wt. % of a modified polyolefin or an olefin copolymer, having functional groups of at least one type selected from carboxyl, carboxylate salt, carboxylic anhydride, amide, hydroxyl and epoxy groups. A typical application of the thermoplastic resinous composition is a laminate having at least two lamine bonded to each other, at least one of the laminae being comprised of the above-mentioned resinous composition and the other being comprised of at least one material selected from vinyl chloride polymer resins, vinylidene chloride polymer resins, thermoplastic polyester resins, ethylene/vinyl alcohol copolymer resins, polyamide resins, polyacrylonitrile and nitrile copolymer resins, polystyrene and styrene copolymer resins, polymethyl methacrylate and acrylic copolymer resins, polyurethane resins, olefin polymer resins, polyacetal resins, polyvinyl acetal resins, polycarbonate resins, polyphenylene oxide resins, polysulfone resins, epoxy resins, phenol-formaldehyde resins, unsaturated polyester resins, melamine-formaldehyde resins, urea-formaldehyde resins, natural and synthetic rubbers, cellulosic materials, cement, glass and other ceramic materials and metals.
