Abstract: Flexible track (1) for converting a wheeled vehicle into a track vehicle. The track comprises a band of elastomeric material (5) reinforced with at least one flexible elongated reinforcing element (7) embedded in the band and extending along the length of the said band, the extremities of the track are respectively provided with at least one hole (14) extending in cross direction of the length of the band and forming a passage (15) for receiving a means (13) for connecting the said extremities, for forming an endless track. The at least one reinforcing element (7) forms a loop around teach of the extremities of the band. The tension stresses endured at the junction of the extremities of the track in operation on the vehicle wheels will be absorbed by the flexible elongated reinforcing element thus avoiding formation of cracks in the band of elastomeric material at the sides of the passage receiving the means for connecting the extremities of the said band.

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 (2, 4) extending in a transverse direction to the axis of the track and, between the wings, a sprocket part (3) which is engaged by a drive sprocket. A protrusion (5, 15) 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.

Abstract: A rubber crawler includes an endless rubber belt directed around two toothed wheels, whereby in the circumferentrial direction of the rubber belt parallel metal core elements are embedded in the rubber belt and extend in cross direction of the rubber belt and are provided for guiding supporting rolls provided between the toothed wheels, each metal core element includes a guiding for guiding the supporting rolls and a carrier for receiving the guiding, and the carrier and the guiding are made as separate parts and are connected to each other.
