Reinforcing cord 15 with a number of reinforcing strips buried in the length direction attached to the middle part in the thickness direction and treated with rubber, etc., and the inner peripheral surface of the rubber body 12 And a guide projection 13 protruding along the longitudinal direction on the center line in the width direction. Further, as shown in the bottom view of FIG. 3 (B), the rubber crawlers 11 are provided with grounding lugs 14A, 14B which are alternately provided on the outer peripheral surface of the rubber main body 12 in a staggered manner. Having.
- wheels 17 A, 1 such as driving wheels, idle wheels or rolling wheels are provided on both left and right sides of the guide projections 13 protruding from the inner peripheral surface of the rubber main body 12. 7 B rolls on the inner peripheral surface of the rubber main body 12.
- the wheel load in which the load of the vehicle is dispersed, is applied from the wheels 17A, 17B to the rubber main body 1 on both sides of the guide projections 13 on the rubber crawler 11.
- the wheel and rubber crawler repeatedly engage and disengage while generating a moment as shown by arrow A by acting vertically on 2.
- FIGS. 4 (A) to 4 (C) are diagrams for simply explaining the mechanism of occurrence of a crack near the base of such a guide projection 13 in a conventional rubber crawler.
- Fig. 4 (A) shows a partial cross-sectional view of a conventional rubber track.
- w is the wheel load
- a is the wheel width
- b is the guide projection width
- other parts or parts are indicated by the same reference numerals as in Fig. 3 (A).
- the load ⁇ is represented by a large number of downward arrows at the top of the reference plane ⁇ _ ⁇ '(ground plane) in Fig. 4 (4).
- an object of the present invention is to provide a rubber crawler that solves the problem of the conventional rubber crawler and suppresses the shearing force in the vicinity of the guide projecting root to effectively prevent the occurrence of cracks.
- an endless belt-shaped rubber main body is provided, and a guide protrusion extending in the length direction is provided on the inner peripheral surface of the rubber main body at the center in the width direction.
- a grounding lug is protruded from the outer peripheral surface, and a non-grounding region is formed in a portion corresponding to a widthwise center portion of the rubber body portion of the grounding lug.
- the non-ground region of the ground lug corresponds to the installation region of the guide protrusion and is formed to have substantially the same width as the guide protrusion.
- This non-ground region is formed by eliminating the protrusion of the ground lug at this portion from the outer peripheral surface of the rubber main body or by reducing the height of the protrusion.
- the rigidity of the rubber main body is improved by embedding a reinforcing cord extending in the length direction in the endless belt-shaped rubber main body.
- the ground lug can be reduced.
- a plurality of lug portions may be formed at predetermined intervals in the length direction of the rubber body.
- FIG. 1 is a cross-sectional view of a lower portion of a rubber crawler showing an embodiment of a rubber crawler of the present invention
- FIG. 2 is a view taken in the direction of arrows A and B in FIG.
- the inner peripheral surface of the rubber body 2 in the form of an endless belt has a guide projecting from the center in the width direction.
- the protrusion 3 is provided so as to extend in the length direction of the rubber body.
- grounding lugs 4A and 4B protrude from the grounding outer peripheral surface of the rubber body 2, and a non-grounding area 6 is provided at a portion corresponding to the installation position of the guide projection 3 of the grounding lugs 4A and 4B. , 6 are formed.
- the reinforcing cord 5 extending in the length direction is embedded in the rubber body 2 in the form of an endless belt.
- the reinforcing cord 5 is composed of a main cord in a longitudinal direction, a bias cord in an inclined direction, and the like, and improves driving resistance and lateral rigidity of the rubber main body 2.
- the guide projection 3 may be composed of a plurality of projections
- the ground lugs 4A and 4B may be composed of a plurality of lugs, and one of the guide projections 3 and the ground lugs 4A and 4B may be provided. Both may be installed at predetermined intervals in the length direction of the rubber body 2.
- both the guide protrusion 3 and the ground lugs 4 A and 4 B are provided at regular intervals in the length direction of the rubber body 2, but only the guide protrusion 3 is set in the length direction. It can be a continuous ridge. Further, the grounding lugs 4A and 4B may be formed continuously on the inclined zigzag strip in the length direction.
- the ungrounded areas 6 and 6 are located at the positions corresponding to the installation positions of the guide lugs 3 of the installation lugs 4A and 4B (shaded portions in Fig. 2), that is, the center in the width direction of the rubber body.
- the grounding lug portion corresponding to the back surface of the central guide protrusion 3 extending or dotted in the longitudinal direction at the portion is formed in advance so as not to touch the ground, or is formed by being cut off.
- a range slightly larger than the width of the guide protrusion is preferably removed.
- the non-ground area 6 may be configured to have an inclined cross section as shown by the hatched portion in FIG. 1 or may be a flat surface protruding lower than other lugs by forming a step portion or the like. .
- the driving form including the shape and material of the rubber crawler and the contact shape with each wheel, and the types of the burning type of the reinforcing cords such as the main cord and the bias cord, etc. , Material and rubberization type, cord angle and embedding position of those reinforcement cords, shape of guide projection, shape of grounding lug, cut form of non-grounding area, cut amount such as width including depth, etc. Can be appropriately changed within the scope of the present invention.
- a guide projection is provided on the inner peripheral surface of the endless belt-shaped rubber body along the length direction at the center in the width direction of the rubber body.
- a grounding lug is provided on the outer peripheral surface of the grounding, and a non-grounding area is formed in the grounding lug corresponding to the installation position of the guide projection on the coreless rubber crawler. Since there is no force, the generation of shearing force in the vicinity of the base of the guide projection can be suppressed, and the generation of cracks can be effectively prevented.
- the reinforcing cord when the reinforcing cord is buried in the length direction of the endless belt-shaped rubber main body, it is backed up by the suppression of the shearing force in the vicinity of the base of the guide projection, and the rubber main body has a driving resistance and a lateral rigidity. It is possible to improve the durability and sufficiently exhibit the durability performance.
- the rubber crawler is smoothly wound around the wheel, and the vicinity of the root of the ground lug tip is provided. Cracks can be reliably prevented by suppressing tensile stress.
- a rubber crawler that suppresses shearing force in the vicinity of a guide projection root and effectively prevents cracks from occurring.
- FIG. 2 is an explanatory view of a rubber track of the present invention.
- FIG. 4A is a diagram illustrating a change in shear force of a conventional rubber crawler
- FIG. 4A is a partial cross-sectional view of the rubber crawler
- FIG. 4B is a diagram illustrating a relationship between a load and a reaction force of a rubber crawler ground contact portion in FIG.
- (C) is the shear force diagram (SFD) of Fig. 4 (B).
