RUBBER TRACK

WIPO Patent Application WO/2017/010756

A1

The present invention presents a rubber track used for an excavator, a loader or the like, and intends to prevent the generation of edge cuts and the like while improving traction force even on soft ground. The rubber track of the present invention comprises: first lugs (10) formed at equal intervals on either the inside or the outside in the direction of movement on the surface thereof coming into contact with the ground, and having first grooves (12) formed in the widthwise direction; and second lugs (20) formed at equal intervals on the other of the inside or the outside in the direction of movement on the surface thereof coming into contact with the ground, and having second grooves (22) formed in the direction of movement. The first lugs (10) and the second lugs (20) perform each independent function such as ensuring the traction force and bendability, preventing a lateral slip, and improving soil discharge properties. In addition, side protruding parts (40) formed to protrude from a surface (2) through lateral surfaces to a back side (4) are provided at the outer sides of the first lug and the second lug so as to improve the traction force even on the soft ground. Furthermore, auxiliary lugs (30) extending in the widthwise direction are respectively provided between the first lugs and between the second lugs so as to prevent the exposure of steel cords and improve the traction force on the soft ground.
