Abstract
The respective ends of the link and grouser of a track link section are shaped so that an enlarged middle portion of a flexor extending between adjacent track link sections is embraced by the link and grouser ends in such a way that the radius of flexure of the flexor is controlled and such that no open volumes ever exist, between the flexor and link and grouser ends, which would allow debris to enter and alter the desired controlled radius of flexure.
Claims1
In an endless track including a plurality of identical track link sections interconnected to each other, each track link section including at least one flexor, which is substantially rectangular in plan view, and includes a tensile load carrying core encapsulated in an elastomeric casing having flat, opposite end portions respectively sandwiched between respective parallel planar portions of a link and grouser of a first track link section, and between respective parallel planar portions of a link and grouser of an adjacent track link section, the improvement comprising:
- said casing including an enlarged portion located centrally between said flat opposite end portions;
- and said links respectively of the first and adjacent track link sections having adjacent ends formed by first and second sets of transversely spaced tabs arranged in overlapping relationship to each other and shaped complementary to and substantially encapsulating one side of the enlarged portion of the casing;
- and said grousers respectively of the first and adjacent track link sections having adjacent ends terminating close to each other and provided with respective surfaces shaped complementary to and cooperating to substantially encapsulate a second side of the enlarged portion of the casing opposite from the one side.
