<p>In track connector links for crawler vehicles, the pins in consecutive track-links are connected together positively and frictionally by means of clamping connectors. To this end, known clamping connector comprises two circular bearing-eyes and a flat stop-face located in the clamping area of the connector, which interrupts the circular shape. The corresponding stopface on the pin extends axially approximately across the width of the clamp and merges, through a transition radius into the circular cross-sectional profile of the pin. As a result of the reduction in cross-section, produced by the stop-race on the pin, and the notch-effect in the vicinity of the transition radius, stresses may arise in service, in the above-mentioned area, which may in time lead to fracture of the pins. This danger of cracks occurring in the pins is eliminated by a pin and connector cross-section which is non-circular and is stepless in the axial direction.</p> |
