Problems solved by technology

[0007] It is therefore clear that if on the one hand the rotating bushings are subject to less wear than fixed bushings fixed into the chain links, on the other hand a track with rotating bushings needs to be provided with some special elements that carry a lot of load, so These elements have a shorter service life than other elements of the track

Embodiment Construction

[0020] With reference to these figures, there is shown a part of a crawler track, generally indicated by the reference numeral 10, having a rotating bushing according to the invention. The crawler track 10 essentially consists of a continuous array of articulated articulation links 12, 12' 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 connected to each other and kept at a constant distance by a pair of links 14 having a longitudinal extension arranged symmetrically transversely with respect to the longitudinal center axis B-B of the track 10.

[0021] Each link 14 is of asymmetrical form, i.e. it is provided with a first end flange 16 facing the outside of the track 10 as seen with reference to the longitudinal central axis B-B, and is provided with a first end flange 16 facing the inside of the track 10, i.e. facing the longitudinal central axis B-B of the tr...

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 at least one sliding bearing (44) is press-fitted between each pin (36, 36′) and the links (14). The presence of sliding bearings (44) made in composite material and having a small thickness and the geometrical / size characteristics of the links (14) and of the sliding bearings (44) themselves makes it possible to improve the stability and the fatigue and wearing resistance of the articulated joints (12, 12′) of the track (10).

Description

technical field [0001] The present invention relates to crawlers for tracked vehicles provided with improved sliding bearings and having rotating bushings, in particular but not exclusively to crawlers with rotating bushings 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 is formed by a continuous arrangement of articulated joints connected to each other and through the "links" called tracks Suitable rigid connection members are maintained at a constant distance. The track also includes a plurality of bushings and pins inserted between the links to connect their ends to form the track. These bushings and supported links cooperate to form track links that allow the necessary rotational movement between adjacent links. This allows adjacent links to articulate as the track rotates about the tracked vehicle's (drive and / or driven) wheels. Rotation of t...
