ABSTRACT:
A connection link for endless track chains is composed of two mutually complementary link portions divided by a separating surface following a broken-line development. Each of the link portions comprises one of the seats for the pins and bushings effecting the mutual link connection. Each of the link portions comprises a tooth and a space arranged in such a way that the tooth of one portion is contained in the space of the other portion. The contact between the two link portions occurs between the sides of the teeth and of the spaces and not on the bottom land (12) of the spaces. Moreover, the faying or closely contacting surface (8) between the internal sides of the teeth and the respective spaces is sloped so as to form obtuse angles with the bottom lands (12) of the spaces, and in order to be more or less perpendicular to the tractive force exerted on the first portion of the link when the link is placed on the track-stretching wheel.
