Abstract:

In some implementations, a flexible track for a tracked vehicle comprises a flexible belt with an inner surface and a ground-engaging surface, the ground-engaging surface comprising outwardly projecting lugs spaced apart along the track, wherein at least one of the lugs comprises a vertical section having a curved leading edge. In some implementations, the flexible track comprises a flexible belt with an inner belt surface, an opposite outer belt surface and at least one track bar attached to the outer surface and extending approximately perpendicular to a direction of the track's travel, the track bar having an outer surface with multiple projecting lugs and an inner surface with at least one holding element, and wherein when the track bar is tightened against the outer belt surface, the holding element engages the outer belt surface, thereby reducing slipping between the flexible belt and the track bar.
