Particularly, the radially outer vane end of each of the swirler vanes is spaced apart from the radially outer sector end of the respective one of the sector openings.

Abstract: A system for braking a track module of a work vehicle includes a frame, a track module supported relative to the frame, and a computing system. The track module includes an idler wheel, roller wheels, a track extending in an endless loop around the idler and roller wheels, and a tensioning actuator configured to adjust a tension on the track. The tensioning actuator increases the tension on the track from a lower tension to a higher tension when a braking operation in association with the track module is initiated and subsequently reduces the tension on the track from the higher tension to the lower tension when the braking operation is ceased.

Abstract: A cab suspension device for an agricultural tractor comprising a pair of concentrically aligned tubes co-axially arranged around a conventional cab suspension spring apparatus. One of the pair of tubes is connected to the tractor frame while the second is attached to the cab frame. The lengths of the tubes are shorter than the static length of the spring apparatus to allow limited telescoping movement of the tubes during dynamic compression of the spring apparatus without causing contact between the tube ends and the opposing tractor and cab frames. The dynamic extension during telescoping movement of the spring apparatus is controlled by a spring retainer. An annular space between the tubes allows for limited lateral displacement of the spring apparatus without causing contact between the tubes. The limits are configured to permit normal operational movement of the spring apparatus without contact of the tubes.

Abstract: Referring more particularly to FIG. 4, the present invention red ices such shear loading on the bolts, by utilizing a wedge member or a tapered block 106, inserted and wedged into a space 108 between wedge surfaces 70 and 88, and having oppositely facing outer surfaces 110 and 112 thereby placed into abutment with those surfaces, respectively, so as to exert a fore and aft directed force against those surface, denoted by arrows C, effectively acting to push those surfaces apart and counteracting the shear loads B. Such forces will also act in opposition to and reduce tensile loads acting on bolts 100. Tapered block 106 has at least one passage 114 therethrough (FIG. 3) for the passage of bolts 104 therethrough, to allow insertion of those bolts into threaded holes 98 and tightening those bolts to exert compressive forces against tapered block 106, denoted by arrows D, for holding that block in position.

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.
