Abstract

PROBLEM TO BE SOLVED: To reduce vibration during travel so as to improve riding comfort by embedding a mandrel in a rubber shoe, forming a bolt hole passing through the mandrel from the tread face side of the rubber shoe corresponding to an installation hole of a link, and fixing both of them by means of a bolt and a nut. SOLUTION: Links 1 are sequently connected to each other by means of link pins 2 so as to be formed into an endless shape, while bolt holes 3 are bored on the outside face sides of the links 1. A plurality of mandrels, E, F, H are embedded in a rubber B over the overall length substantially in the lateral direction of a rubber shoe A1 , and in the mandrel F, a head part G rising slantingly toward the link 1 is protruded from the inside of the rubber B over the overall length. The mandrel H is slantingly protruded downward from the inside of the rubber B toward the link 1 by forming a tail part I opposedly to the head part G. Bolt holes D are formed corresponding to the bolt holes 3 individually, and a bolt 4 is inserted toward each bolt hole 3 so as to be fastened and fixed by means of a nut 5. Therefore, vibration during travel can be reduced.

2. Description of the Related Art In recent years, construction machines operating in civil engineering work in urban areas do not damage road surfaces when traveling on paved road surfaces. Rubber crawler belts have come to be used more favorably because of higher friction and higher traction. As shown in FIG. 7, a conventional rubber crawler comprises a pair of grosses 13 and 1 on the grounding surface side of a shoe 12 attached to a link 11 of the crawler.
It is usual that a rubber pad 10 is interposed between the three and fixed by bolts 14 and nuts 15. There is also an example in which the rubber pad 10 is vulcanized and bonded directly to the shoe 12. Further, as shown in FIG. 8, a groove 16 is provided on the opposing surfaces of the pair of grosses 13, 13, while a groove 17 is also formed on the rubber pad 10,
It is also considered that after these are fitted, the pins 18 are driven into the grooves 16 and 17 to fix them.
