ABSTRACT:
A two-piece master track link for connecting an endless track for heavy duty track vehicles, consists of two half-links each having a mating surface comprising of a recess and a hook-like projection, so that the hook-like projection of one link part is received in the recess of the other link part. The recesses and hook-like projections are so shaped that in assembling of the half links by screws or bolts all the mating surfaces adhere to one another and prestress the screws owing to the configuration of their profiles. Said profiles consist each of an oblique portion merging into a substantially horizontal portion merging in turn into a central portion inclined with respect to an imaginary vertical plane at the angle of friction of about 10.degree. and sized to have a ratio with respect to said oblique portion ranging between 1 to 4. An imaginary horizontal plane including the axes of said pin and bushing bores divides said central portion in a first central sector and a second central sector, the size ratio between said first and second sector ranging from 0 to infinite in dependence upon the weight and thus stiffness ratio between said first and second link parts for balancing the elastic deformability of said two half-link whereby by tightening said screws into the track link the oblique portions of said first link part tend to slightly displace relative to oblique portions of said second link part so that the entire contacting surfaces of the both link part adhere to one another owing to the mutual elastic deformation of the link parts, thus also avoiding loosening and unscrewing of said screws during operation.
