摘要： A track belt comprises a bearing element having an inner surface, an outer surface and a width. On the inner surface, a guide element extends in the longitudinal direction of the track belt, comprising a first edge protrusion and a second edge protrusion. The width of the guide element is substantially smaller than the width of the bearing element. The track belt comprises a first guide groove having a first flank surface formed by the first edge protrusion, and a second guide groove having a first flank surface formed by the second edge protrusion. The first flank surfaces of the edge protrusions are uniform and continuous substantially over the entire length of the guide element. Preferably, the guide element comprises a traction surface parallel to the inner surface of the bearing element, having engaging members for receiving the engaging parts of the drive wheel.

摘要： Compensating cylinders are provided for pairs of transverse steering linkages connecting pairs of tractors that steer in unison on opposite sides of a main frame of a heavy construction machine whereby the steering linkages automatically extend and retract to accommodate the changes in length imposed by changes in the slope or off-sets in the grade being negotiated by the machine.

摘要： A vehicle which has a pair of end rolls and an endless track guided around the end rolls is provided at its endless track with a central substantially non-stretchable region cooperating with the endless track structure to render the latter substantially rigid at the ends of the track which extend around the end rolls to prevent any slipping of the track with respect to the end rolls particularly when at least one of the end rolls is swung about an upright axis to enable the vehicle to execute a turn. On opposite sides of its central endless region the endless track has a pair of opposed lateral regions capable of automatically expanding and contracting when the vehicle executes so that the inside lateral region contracts while the outside lateral region expands during a turn, and the manner of contraction and expansion of these lateral regions of the endless track is such that together with a curving of the central non-stretchable region the endless track assumes a smooth, substantially uniform curved configuration when the vehicle executes turns.

摘要： There is provided a singly steerable, serpentine steel track crawler. The single-track crawler can steer independently in a serpentine fashion. Two or more single crawler tracks side-by-side can be transformed into a multi-track crawler vehicle. The single-track crawler or multi-track crawler vehicle can be fitted with rubber tires for plying on paved roads. This makes it a versatile, multi-terrain vehicle for agriculture and earth-moving applications.

摘要： A steering system for tracked vehicles having two brake circuits which is activated after a failure of the primary steering mechanism. The steering system includes a steering switch (L) that can be controlled by a steering axle which, in the event of primary steering system failure, acts upon the brakes of the vehicle in such a manner that rotation of the steering axle results in a braking action upon a track on the inside of a curve.

摘要： A mounting mechanism for an endless traction band system in which the endless band is supported on and driven by a pair of laterally spaced roller chains. The mounting mechanism supports a double sprocket for engaging the chains and is adapted to permit a limited degree of skewing by the sprocket wheel shaft so as to maintain the sprockets in alignment with the roller chains even when the roller chains are deformed in response to laterally imposed loads.
