<p>A rubber track which has good ground gripping properties and soil discharge properties to achieve sufficient traction force and straight traveling properties and is highly durable. A rubber track (1) having cores (30) which are embedded in a track body (10) and also having lugs (13) which are provided on the outer peripheral surface of the rubber track, the lugs (13) being divided to the left and right by the center portion (11) and arranged in a staggered pattern having a phase shifted in the circumferential direction, wherein the rubber track (1) comprises grooves (18) each dividing the ground contact surface of each lug (13) into the center-side lug section (20) and an outer-side lug section (22). During traveling, the center-side lug sections (20) and the outer-side lug sections (22) of the lugs (13) continuously make contact with the ground to cause the cores (30) to be supported by the lugs (13) by sufficient force. As a result, separation and cracks in the track body (10) are prevented from occurring to improve the durability of the track body (10) including the lugs (13). Also, muddy soil, etc. caught in the grooves (18) which extend in the circumferential direction are not destroyed. As a result, ground gripping properties and soil discharge properties are maintained, so that the rubber track can maintain straight traveling properties to prevent a side slip on the soft ground, sloping ground, etc.</p> |
