The invention refers to a truck roller assembly (12) for a crawler chain comprising at least two spaced track roller portions (5, 5') with running surfaces for running on the crawler chain (13), and a star-shaped element (6) for guiding the track roller assembly (12) on the crawler chain (13).

The invention refers to a truck roller assembly (12) for a crawler chain comprising at least two spaced track roller portions (5, 5') with running surfaces for running on the crawler chain (13), and a star-shaped element (6) for guiding the track roller assembly (12) on the crawler chain (13). The star-shaped element (6) is mounted freely rotatably between the at least two track roller portions (5, 5'), and it is provided with a plurality of teeth (6', 6", 6'", 6"", 6'""). The teeth (6', 6", 6'", 6"", 6'"") co-operate with the crawler chain (13) in such a way that on rolling over chain links (3) of the crawler chain (13) they engage into corresponding gaps (8) in the crawler chain (13). The teeth (6', 6", 6'", 6"", 6'"") extend beyond the running surfaces of the at least two track roller portions (5, 5') and between projections (7, 7') of the crawler chain (13) such that it is ensured that the crawler chain (13) Is not displaced laterally relative to the track roller portions (5, 5') and does not roll up on to the projections (7) of the crawler chain (13). In an alternative embodiment the star-shaped element is replaced by an idling roller (11).

The invention claimed is: 1. A track roller assembly for a crawler chain having at least one row of projections provided on an inner surface of said crawler chain, said track roller assembly being adapted for mounting in a crawler carrier, said track roller assembly comprising: at least two spaced
The invention claimed is: 1. A track roller assembly for a crawler chain having at least one row of projections provided on an inner surface of said crawler chain, said track roller assembly being adapted for mounting in a crawler carrier, said track roller assembly comprising: at least two spaced track roller portions mounted on a shaft having a center axis coinciding with a roller axis of the respective track roller portions, said at least two spaced track roller portions comprising running surfaces for running on said crawler chain, wherein the track roller assembly rests on the crawler chain, and idling means for guiding said track roller assembly on said crawler chain, wherein said idling means is mounted in front of said at least two spaced track roller portions, wherein said idling means is pivotally mounted on said shaft, so that said idling means is pivotal about the center axis of the shaft, and wherein said idling means is operatively arranged for remaining in contact with a run of said crawler chain, on which the running surfaces rest, to avoid lateral displacement relative to said two spaced track roller portions or roll up on to the at least one row of projections of said crawler chain. 2. The track roller assembly according to claim 1, wherein said idling means comprises a pair of rollers rotatably mounted on a front shaft positioned in front of the at least two track roller portions. 3. A crawler chassis comprising: a crawler carrier, a crawler chain having at least one row of projections provided on an inner surface said crawler chain, at least one track roller assembly comprising at least two track roller portions with surfaces for running on said crawler chain besides said at least one row of projections, wherein the at least two track roller portions of a track roller assembly have a common roller axis, wherein the at least one track roller assembly rests on the crawler chain, and idling means for guiding said track roller assembly on said crawler chain, wherein said idling means is pivotally mounted with respect to the track roller portions, so that said idling means is pivotal about the common roller axis of the at least two track roller portions, and wherein said idling means is arranged in front of said at least two track roller portions, and wherein said idling means remains in contact with a run of said crawler chain, on which the surfaces for running rest, to avoid lateral displacement relative to the track roller portions or roll up on to said at least one row of projections of said crawler chain. 4. The crawler chassis according to claim 3, wherein said idling means comprises an idling roller having an outer peripheral surface operatively arranged such that said at least one row of projections of the crawler chain is laterally guided by said idling roller. 5. The crawler chassis according to claim 4, comprising two rows of projections arranged in mutually spaced relationship on said crawler chain and said idling roller of said track roller assembly is in the form of a pair of rotatable rollers on a front shaft arranged with a gap therebetween, wherein said rollers are operatively arranged such that the two rows of projections enter into said gap. 6. The crawler chassis according to claim 3, further comprising a shaft, wherein said at least two track roller portions are rotatably mounted on said shaft and the idling means of the track roller assembly is pivotally mounted on said shaft. 7. The crawler chassis according to claim 3, wherein said crawler chain is an endless chain.
