Abstract
The invention relates to a self-propelled, wheeled vehicle that may be converted into a multi-track self-propelled vehicle using one or more track assemblies. Each track assembly includes a carriage with a main frame that support forward and rearward idler wheels and a plurality of centrally located, inner bogey wheels, and an outrigger beam that supports a plurality of centrally located, outer bogey wheels. One of the idler wheels is movably connected to the main frame and is movable by an actuator. The carriage is removably connected to a spindle of a vehicle by an attachment assembly. The attachment assembly includes a first or lower section and a second or upper section that generally encircle a portion of the spindle housing, and which are connected thereto by a plurality of fastening elements. A sprocket is operatively connected to a wheel hub of the spindle either directly or indirectly by way of a spacer element. A flexible endless track is entrained about the idler wheels, the bogey wheels and the sprocket.
