Abstract
This invention relates to a molded crawler track comprising metallic core bars set in an endless rubber belt. The core bars comprise first and second wings ( ) extending in a transverse direction to the axis of the track and, between the wings, a sprocket part ( ) which is engaged by a drive sprocket. A protrusion ( ) is provided on either side of the sprocket part, i.e. protruding out of the plane of the wings towards the guide wheel for the track. The protrusions serve to guide the track over the guide wheels. The protrusions are inclined; one forward, one towards the rear; The relative dimensions of the elements of the core bars, are given. This combination of features reduces the occurrence of fatigue fractures and cracks in the belt.
