Problems solved by technology

[0011] Therefore, it is clear that if on the one hand the rotating bushings are subject to less wear than the fixed bushings fitted into the chain links, on the other hand a track with rotating bushings in which some specific elements carrying large loads are required and therefore These specific elements have a shorter working life than other elements of the track

Embodiment Construction

[0025] Referring to the drawings, there is shown a portion of a track generally indicated by the reference numeral 10 having rotating bushings in accordance with the present invention.

[0026] The track 10 essentially consists of a continuous series of articulated connections 12 , 12 ′ of the hinge type oriented according to an axis A-A substantially perpendicular to the central longitudinal extension axis B-B of the track 10 . The articulated connections 12 , 12 ′ are interconnected and held at a constant distance by a pair of links 14 having a longitudinal extension, arranged transversely and symmetrically with respect to the longitudinal center axis B-B of the track 10 .

[0027] Each link 14 is of the asymmetric type, that is to say provided with a first end flange 16 facing the outside of the track 10 if seen with reference to the longitudinal center axis B-B and with a second end flange facing the inside of the track 10 18 (or in other words, facing the longitudinal cen...

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).

Description

technical field [0001] This invention relates to a track with rotary bushings for tracked vehicles, and more particularly, but not exclusively, to a track with rotary bushes for tracked vehicles for ground movement. Background technique [0002] The track of a tracked construction vehicle usually consists of a pair of parallel tracks, each track obtained by a continuous series of hinge-type articulated connections through suitable rigid connecting members (called "chains" of the track). section") are interconnected and kept at a constant distance. [0003] The track also includes a plurality of bushings and pins inserted between the links to connect their ends to form the track. The bushings and supporting links cooperate to form multiple track linkages that allow the necessary rotational movement between adjacent links. This allows the articulations of adjacent links to wrap around the (drive and / or driven) wheels of the tracked vehicle as the track rotates. Rotation of ...
