Abstract:
A track (10) for track-type vehicles is described, comprising a continuous sequence of articulated joints (12, 12′) of the hinge type, oriented according to a first axis (A-A) substantially perpendicular to the central longitudinal development axis (B-B) of the track (10). The articulated joints (12, 12′), provided with pins (36, 36′), are connected to each other and maintained at a constant distance through pairs of links (14) having longitudinal development, arranged laterally and symmetrically with respect to the longitudinal central axis (B-B). Around each pin (36, 36′) a bushing (40) is mounted free to rotate with respect to the pin (36, 36′) itself and between each pin (36, 36′) and the links (14) at least one sliding bearing (44) is press-fitted. The geometric/size characteristics of the links (14) and of the sliding bearings (44) make it possible to improve the stability and the resistance to fatigue and wearing of the articulated joints (12, 12′) of the track (10).
