초록 ▼

A converter assembly for converting a drive-wheel-driven tractor into a track-driven tractor, the assembly having its frame separate and unattached relative to the frame of the tractor and constructed and arranged, together with a continuous track, to be positioned beneath the drive-wheel of the tractor, and within the track, in cooperating position with the drive-wheel and track, to effectively extend the ground-engaging area of the tractor. A pair of transversely spaced, relatively light, plate members rotatably mount a pair of idler wheels, one ahead and one behind the drive-wheel within the track. A pair of alignment rollers are also rotatably mounted between the plate members in engaging and aligning relation ahead and behind the drive-wheel, whereby the converter assembly is maintained in aligned relation with the drive-wheel, and some of the weight is transferred from the drive-wheel, through the alignment rollers and plate members, to the idler rollers. The plate members permit easy application of the converter assembly to, or withdrawal from, the drive-wheel by merely jacking the latter into an elevated position and applying or removing, as the case may be, the converter assembly and track by merely removing the outside plate member before applying or removing the assembly form the drive-wheel, and re-applying same after the lower portion of the drive-wheel is extended into the track and assembly or is removed therefrom, as the case may be. The entire converter assembly is otherwise entirely unattached relative to the frame of the tractor.

A track-driven vehicle comprising: (a) a tractor having at least one pair of drive-wheels on a common axis; (b) a pair of auxiliary-drive-assemblies separate from said tractor and each of which is associated with and disposed below the axis of one of said drive-wheels in driven relation thereto, and includes at least a pair of rotatable members each of which is rotatably mounted outside the circumferential periphery of said drive-wheel for rotation about an axis substantially parallel to and at opposite sides of the axis of said drive-wheel with the lower portion of its circumferential periphery adjacent the plane of the lower portion of the circumferential periphery of said drive-wheel and being driven indirectly by said drive-wheel; (c) means for transmitting at least a portion of the load upon said drive-wheels to each of said auxiliary-drive-assemblies; (d) each of said auxiliary-drive-assemblies being unsupported by said tractor and including rotary aligning means engaging one of said drive-wheels in aligning relation and maintaining the assembly in which it is included in aligned relation with the drive-wheel engaged by said aligning means; and (e) a continuous flexible drive-track extending tautly around said drive-wheel and said rotatable members in driven relation to said drive wheel to provide a track-drive for said tractor.
