Document Type and Number:
WIPO Patent Application WO/2008/023820
Kind Code:
A1
Abstract:
A rubber track having increased durability achieved by reducing teeth skipping phenomenon
occurring between a sprocket at the vertex of a triangular chassis portion and
rubber projections of the rubber track. The rubber track is passed over the sprocket
provided on a vehicle and idlers arranged on the left and right of the sprocket,
and the track forms a triangular shape with the sprocket as the vertex. The rubber
projections (22) are raised on the center of the inner peripheral surface of the
track, at predetermined intervals in a travel direction. The rubber track satisfies
the expression of C ≤ A, with A the length of a projection (22) in the lateral
direction normal to the travel direction, C the pitch in the travel direction
of the rubber projections.
