Abstract: A track assembly 30 for converting a wheeled vehicle 10 into a tracked vehicle. The track assembly 30 has a longitudinally adjustable support frame 40 having a motive source 170 with a drive sprocket 190, a plurality of support rollers 80, 84, 88, a tensioning assembly 90, and an endless track 200. The track assembly 30 is connected to a vehicle 10 by articulated, resiliently biased mounting assemblies 210, 410. Each mounting assembly 210, 410 includes a first attachment member 212, 412, a link 250, 450, and a second attachment member 300, 500, with the first attachment member 212, 412 configured to be removably attached to a position on a vehicle 10 where a wheel axle attached to an internal drive unit 19 would normally reside but which has been disconnected from its control lines and removed, and with the second attachment member 300, 500 configured to be connected to the support frame 40.

Abstract: A track assembly having a carriage with frames that support a plurality of idler and bogey wheels. A portion of one of the frames is telescopically received within a portion of the other frame. A tensioning apparatus is connected to the frames so that they are adjustable relative to each other. Each carriage may include an offset hub support frame that includes an aperture that rotatably receives a spindle of an adaptor. The adaptor includes a peripheral flange to which a segmented sprocket may be connected, and a ring extension that may be connected to a wheel hub of an irrigation vehicle. A flexible endless track, that is entrained about the wheels and the sprocket may be provided with one or more cleats that are removably connected to the flexible, endless track, with each cleat including a ground engaging member that serves to increase the traction of the endless track.

Abstract: The invention relates to a self-propelled, wheeled irrigation vehicles (10) that may be converted into a multi-track self-propelled irrigation vehicle (60) using one or more track assemblies (62). Each track assembly (62) includes a carriage (70) with frames (92, 94) that support a plurality of pairs of idler wheels (74, 76), and pairs of bogey wheels (80, 82, 84). A portion of one of the frames (94) is telescopically received within a portion of the other frame (92), so that the frames (92, 94) may move relative to each other in a linear fashion. A tensioning apparatus (212) is connected to the frames (92, 94) so that the frames are adjustable relative to each other. Each carriage (70) also includes a hub support frame (90) that is connected to one of the frames (92) in an offset manner. The hub support frame (90) includes an aperture (132) that rotatably receives a spindle (262) of an adaptor (258).

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.

Abstract: A track assembly having first and second hub assemblies that are operatively connected to a support frame by first and second attachment members, respectively. The first and second attachment members include resilient or movable mounts that are configured so that the track assembly can be attached to vehicles whose axles or wheel flanges are misaligned or have irregular rotational movement such as runout or wobble. The attachment members may be adjustably positioned relative to the support frame to accommodate vehicles having different wheelbase lengths and axle lengths. An endless track encircles the first and second hub assemblies, and the support frame, and is drivingly engaged by one of the hub assemblies. First and second rollers, which define the longitudinal extent of the endless track, are positioned at either end of the support frame. A tensioning member, with at least one upper idler roller, positions the endless track so that it is spaced from one of the hub assemblies in a spaced relation.

Abstract: A flexible track used for wraparound mounting on construction vehicle tires including a main pad assembly and a lift link assembly. The lift link assembly has a link component and a link pad pivotally connected to the main pad assembly for increasing track flotation and durability. The link component has a link base pivotally connected to the main component of the main pad assembly. The link component also has a link top that has a bonding aperture and is perpendicular relative to the link base forming an overhang. The link pad has a side wrap and under wrap. The link pad is rigidly connected to the link component for reducing track damage to the ground.

Abstract: The soft bottom track assembly of the present invention includes inner pad assemblies, side plate assemblies, and link and cross bolt assemblies. An inner pad assembly includes a multiplicity of longitudinally arranged pads, hingedly attached one to the next, each having an upper iron casting with a rubber/urethane material bonded thereto. The pads are arranged in rows, with each row staggered from each adjacent row so that there are always pads in contact with the surface on which the track is riding. A raised area on the cast iron backing provides traction between the tire and the track assembly. Each pad includes holes for hinged attachment to adjacent pads, also permitting adjustment of the size of the track length, depending on the hole arrangement selected during track assembly installation.
