Abstract
The invention relates to track systems 14, 14′ that may be used to convert steerable, all-wheel drive construction equipment to steerable, multi-track construction vehicles 10. A preferred embodiment of the track system 14, 14′ includes a frame 60, 182 having a reinforcing enclosure 150, 230, a plurality of track engaging rollers 82-86, 202-206, a sprocket 102, 214, and an endless track 76, 198 operatively connected to the frame 60, 182. Tension on the endless track 76, 198 is maintained with two tensioning members 170, 244 operatively connected to the forwardmost roller 82, 202. The track system 14, 14′ preferably includes a limiting apparatus 300 that is configured to restrict the rotational movement “r” of the frame 60, 182 relative to a vehicle axle 16 to which it is attached. The limiting apparatus 300 has a first component 40, which is associated with the vehicle axle 16, is configured and arranged to interact with a second component 262, which is associated with the frame of the track system 14, 14′. Preferably, the limiting apparatus 300 is adjustable such that the range of rotational movement “r” can be varied.

66. A track system comprising:
-
a frame having a first end and a second end, the frame having inboard and outboard frame assemblies that extend between the first and second ends of the frame; a drive sprocket mounted between the inboard and outboard frame assemblies such that inboard frame assembly is inboard of the drive sprocket and the outboard frame assembly is outboard of the drive sprocket, the drive sprocket being rotatable relative to the frame about an axis of rotation; a first end roller mounted at the first end of the frame; a second end roller mounted at the second end of the frame; a track routed in a generally triangular path about the drive sprocket and the first and second end rollers, the track being driven by the drive sprocket about the generally triangular path when the drive sprocket is rotated about the axis of rotation; and inboard and outboard cylinders for moving the first end roller relative to the frame to tighten the track, the inboard and outboard cylinders being in fluid communication with one another, the inboard cylinder being inboard of the drive sprocket and the outboard cylinder being outboard of the drive sprocket. - View Dependent Claims (67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89)

90. A track system comprising:
-
a frame having a first end and a second end, the frame having first and second frame components that extend between the first and second ends of the frame; a drive sprocket mounted between the first and second frame components, the drive sprocket being rotatable relative to the frame about an axis of rotation; a first end roller mounted at the first end of the frame; a second end roller mounted at the second end of the frame; a track routed in a generally triangular path about the drive sprocket and the first and second end rollers, the track being driven by the drive sprocket about the generally triangular path when the drive sprocket is rotated about the axis of rotation; and first and second cylinders for moving the first end roller relative to the frame to tighten the track, the first and second cylinders being in fluid communication with one another. - View Dependent Claims (91, 92, 93, 94)
