<p>Means are described for bogie mounting a roller (94) to an idler (88) on a crawler track undercarriage (10) such that the benefits of load transfer and shock absorbance are provided for a single roller-idler combination on a tracked vehicle. A tracked undercarriage (10) has a track frame (12) to which is pivotally mounted a support link (34), and pivotally mounted thereto a bogie link (60). Rotatably mounted on the bogie link (60) are an idler (88) and a roller (94). Variations in ground level cause the bogie link (60) to rotate such that resilient pads (98, 106) are compressed thereby absorbing shock and so that the roller (94) is less heavily loaded and the idler (88) has its loading increased.</p> |
