摘要： The present invention provides a rubber track used for an excavator, a loader, or the like and prevents occurrence edge-cuts and the like while improving traction force even in the soft ground. The rubber track of the present invention is configured by first lugs 10 which are formed at equal intervals on one side of the inside and the outside in a traveling direction on a surface coming into contact with the ground and have first grooves 12 formed in a width direction; and second lugs 20 which are formed at equal intervals on the other side of the inside and the outside in a traveling direction on a surface coming into contact with the ground and have second grooves 22 formed in the traveling direction. The first lug 10 and the second lug perform independent functions, respectively, and for example, may secure traction force and flexibility, prevent a side slip, and improve extraction performance. In addition, at the outsides of the first lug and the second lug, side protrusions 40 formed to protrude from the surface 2 to the back surface 4 through the side are provided, thereby improving the traction force even in the soft ground. In addition, auxiliary lugs 30 extending in a width direction are provided between the first lug and the second lug, thereby preventing exposure of a steel cord and improving traction force in the soft ground.
