Title:
RUBBER CRAWLER HAVING METAL CORE FOR IMPROVEMENT OF WHEEL SEPARATION AND DURABILITY
Document Type and Number:
WIPO Patent Application WO/2011/093590
Kind Code:
A2
Abstract:
The present invention relates to a rubber crawler having a metal core for improvement of wheel separation and durability, and comprises metal core extensions formed at predetermined intervals along the lengthwise direction of the metal core of the rubber crawler, thereby avoiding the phenomenon of wheel separation which occurs during crawler operation, and minimizing rubber breakage due to foreign objects, bend fatigue, metal core exposure and breakage of a tread section, so that the durability performance is enhanced. According to an embodiment of the present invention, the rubber crawler having a metal core for improvement of wheel separation and durability comprises: a lug formed to protrude on an external side surface and grounded on the terrain; a steel cord disposed internally for enduring compressive load and the driving load of a tracked vehicle; a metal core which is embedded within the steel cord, and transfers the driving force of the engine; and metal core extensions which are embedded along both lengths on the basis of the center section of the metal core, and prevents wheel separation of the metal core, wherein the metal core extensions are assembled on the mutually opposite surfaces of which are inclined at a predetermined angle, and the overlapped section (center section) surfaces of the metal core extensions are formed to have an angle of inclination to each other, thereby supporting the X axis, Y axis, and z axis displacements.
