Definitions
- the present invention provides a rubber crawler that suppresses the generation of cracks mainly due to bending deformation during winding of a coreless rubber crawler.
- a coreless rubber crawler has an endless rubber elastic body in which a steel cord is embedded in the longitudinal direction thereof, and a rubber protrusion formed at a constant pitch for driving on an inner peripheral side, and an outer peripheral side Also equipped with a rubber lug formed with a single pitch! /
- the steel cord becomes the center of tension of the rubber crawl and is struck against a sprocket or idler, the rubber on the inside repeatedly receives the strain on the compression side, and the rubber on the outside is distorted on the tension side. Will be repeatedly received.
- the bending rigidity is low between the rubber protrusions because the bending rigidity is low between the rubber protrusions.
- An object of the present invention is to reduce the number of cracks caused by bending during winding as much as possible and to improve the life of a rubber crawler.
- the first gist of the present invention is a steel cord in an endless rubber elastic body in its longitudinal direction.
- the left and right rubber lugs are composed of an inner end region and an outer end region, and a central region connecting both of them.
- the second gist of the present invention is that the rubber protrusions are arranged on the inner peripheral side of the rubber crawler with a constant pitch, and the inner end region and the outer end region of the rubber lug are similar to the pitch of the rubber protrusions. It is characterized by being arranged at a pitch.
- a fourth aspect of the present invention is characterized in that the connection region exists at least between the rubber lugs corresponding to the wheel passing surface.
- FIG. 5 is a plan view of the outer peripheral side showing a second embodiment of the rubber crawler of the present invention.
- the central region 4c is inclined, the overall rigidity of the rubber crawler is more uniform than that of the rubber crawler having the conventional structure. A reduction was also achieved.
- the inner end region 4a and the outer end region 4b of the lug are arranged so as to extend in the rubber crawler width direction.
- the boundary between the rubber lug (high rigidity part) and the rubber lug (low rigidity part), especially the inner edge area 4a of the rubber lug Although the strain should preferentially concentrate on the outer end region 4b, the above-mentioned both end regions extend in the rubber crawler width direction to extend the generated strain in a wide range. Since it will be received, cracks are less likely to occur.
- the connecting region 4d is disposed between rubber lugs corresponding to the wheel passing surface 5 of the wheel passing through the inner peripheral surface of the rubber crawler.
- the rubber lug 4 is subjected to high contact surface pressure due to the passing of the wheel, but the rigidity of the rubber lug at this portion is increased, and cracks can be effectively prevented from occurring. .
- the H-shaped lug is shifted by 1 pitch on the left and right of the central force of the rubber crawler, the wheel always passes over the coupling area 4d, so that the generated vibration can be further reduced.
