  • Patent number: 10005506
    Abstract: A suspension assembly is provided for use with a vehicle having a chassis enclosing a drive system for rotatably driving a closed-loop track. The suspension assembly includes at least one elongated ground contact engaged with the closed-loop track, and an elongated swing arm angularly disposed in the closed-loop track. The swing arm extends between a front end portion adapted to be coupled to the chassis, and a rear end portion coupled to the at least one ground contact. A mounting arrangement is coupled to the swing arm for permitting at least rotation of the swing arm about a pivot axis extending longitudinally of the at least one ground contact wherein the mounting arrangement includes a wire rope mount.
    Type: Grant

  • Patent number: 8360449
    Abstract: A suspension assembly for a land vehicle comprises a spindle defining a steering axis for the land vehicle and configured to pivotably couple to a ground contact; an upper pivotable member having an inboard end configured to pivotably couple to the land vehicle and an outboard end pivotably coupled to the spindle; a lower pivotable member having an inboard end configured to pivotably couple to the land vehicle and an outboard end pivotably coupled to the spindle; a resilient member having an upper end configured to pivotably couple to the land vehicle and a lower end pivotably coupled to the spindle; a caster adjustment mechanism adjusting the position of one of the upper pivotable member and lower pivotable member relative to the spindle to thereby adjust caster; and a camber adjustment mechanism adjusting the position of one of the upper pivotable member and lower pivotable member relative to the spindle to thereby adjust camber.
