Abstract

PURPOSE:To prevent removal of caterpillar by burrying U-shaped core member in the caterpillar body and projection while further burrying a reinforcing member in the lower side of horizontal section of said core member thereby increasing the rgidity of projection without increasing the amount of rubber. CONSTITUTION:Projection 2 to be geared with pins of drive wheel are arranged in the central portion of catapillar body 1 while lugs 3 are formed at the grounding face side. Two projections 2 are formed laterally on the caterpillar body 1 and arranged longitudinally with interval. An U-shaped core member 4 is burried in said projection 2 while reinforcing member 5 such as wire cord, steel cord, etc. is burried in the lower side of horizontal portion 4a of core member 4. Consequently, the rigidity of projection is improved to prevent removal of caterpillar.

であるために変形し、脱輪し易いという欠点があった。Conventional elastic endless track belts include a type in which meshing holes for sprocket teeth are formed at equal intervals in the longitudinal direction of the center of the track belt, and a type in which meshing holes for sprocket teeth are formed at equal intervals in the longitudinal direction of the center of the track belt, and a type in which meshing holes for sprocket teeth are formed on the inner surface in the longitudinal direction of the center of the raceway band instead of such meshing holes. There is a type in which engaging protrusions are formed at equal intervals, and the pin of the drive wheel engages with these protrusions. As the latter pin drive type, those shown in FIGS. 1 and 2 are known. A plurality of pins 12 are provided around the axle 11 of the drive wheel 10, an idler wheel 13 is provided at a certain distance from the drive wheel 10, and a track belt 100 is provided between these two wheels 10 and 13. It's just me. Further, the wheels 14 are configured to run while touching the ground on both sides of the track belt 100. In the center of the inner surface of the track band 100, projections 101 for engaging with the pins 12 are arranged in a row at regular intervals in the longitudinal direction, and on the outer surface, lugs 102 are arranged in a row. . Such a bin drive type track belt 100 is used for relatively lightweight vehicle machines such as small snow blowers and harvesters. In the conventional example shown in FIG. Since the bottle 12 is made of iron, the iron and rubber mesh together,
Straw and the like get wrapped around the track belt, preventing reliable driving and causing damage to the track belt 100. Furthermore, as shown in FIG. 3, when a force is applied from the side, the protrusion 101 is made of rubber, so it deforms and easily comes off the wheel.

る。This invention was made in order to eliminate the drawbacks of the conventional bottle drive type, by increasing the rigidity of the protrusion that engages with the bottle without increasing the volume of the rubber etc., thereby preventing wheels from slipping off and preventing straw from becoming entangled. [Structure] In order to achieve the above-mentioned object, the present invention provides a cloth main body formed in an endless shape from an elastic material such as rubber. A roughly U-shaped core material is buried along the yam direction at regular intervals with its protruding pieces on both sides protruding toward the inner surface. A reinforcing member is embedded in the side, a protrusion is formed on the protrusion piece of the core material so as to cover it, and as a result, the protrusion piece is embedded within the protrusion.

とができ、さらに全体としての強度も向上した。As explained above, according to the present invention, the entire body is formed of an elastic material such as rubber in an endless shape, and the projections that engage with the pins of the drive wheels are arranged in a row at regular intervals along the longitudinal direction at the center of the inner surface. In this elastic endless track belt, a roughly U-shaped core material is embedded in the fabric body and the protrusions, and a reinforcing member is embedded below the horizontal part of the core material, so that the rigidity of the protrusions is lower than that of the rubber. This increased the height without increasing the amount, making it possible to prevent the occurrence of wheel derailment, and further improving the overall strength.
