  • Patent number: 6217135
    Abstract: In the case of highly mobile vehicles overloading of the travelling pads (3) of crawler tracks frequently gives rise to incipient cracks in the base plate (14), which generally start from the bottom of the incision of the tongue. A long service life for the travelling pad (3) with base plate (14) is achieved by the base plate (14) being incision-free in the retaining region (10).

  • Patent number: 5058963
    Abstract: A belt-type Caterpillar for track-laying vehicles and snowmobiles, incorporating individual replaceable belt segments, in which each belt segment incorporates a base member consisting of rubber including tensile-loaded inserts which encompass a traction or tie anchor transversely supported within the rubber in the region of the connecting locations for the belt segments. The connecting locations which are formed as hinge members vulcanized into the belt segments include tubular sections with inserted tubes or track pins, as well as arms arranged at a lateral spacing from each other, whereby the arms retain the tie anchor which is formed as a connecting pin or bolt. The inserts consist of at least two endless fabric bands or webs arranged at a spacing adjacent each other, the arms terminating proximate a nonelastic bending region of a rubber or track dog, or transversely stiff traverse, and in which the hinge members possess laterally arranged arms.
