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.

1. A suspension assembly adapted for use with a vehicle having a chassis enclosing a drive system for rotatably driving a closed-loop track, the suspension assembly comprising at least one elongated ground contact engaged with the closed-loop track, an elongated swing arm angularly disposed in the closed-loop track, the swing arm extending 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, and a mounting arrangement 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 comprises a wire rope mount; wherein the wire rope mount includes at least one resilient wire rope element, a first mounting element connected to an upper end of the at least one wire rope element and attached to the rear end portion of the swing arm, and a second mounting element connected to a lower end of the at least one wire rope element and attached to the at least one ground contact;wherein the upper end of the wire rope mount includes an upper mounting block, and the lower end of the at least one wire rope element includes a lower mounting block; andwherein the first mounting element is a cradle which receives the rear end portion of the swing arm, and is connected to the upper mounting block of the at least one wire rope element. 2. The suspension assembly of claim 1, wherein the at least one wire rope element is encapsulated in an elastomeric material. 3. The suspension assembly of claim 1, wherein the wire rope element has a longitudinal axis oriented either transversely or angularly relative to the pivot axis and the at least one ground contact. 4. The suspension assembly of claim 1, wherein the at least one wire rope element is configured for compression responsive to loading on the swing arm, and configured for expansion responsive to release of loading on the swing arm. 5. The suspension assembly of claim 1, wherein the second mounting element is a mounting bar having outer ends fixed to the at least one ground contact, and an upper surface joined to the lower mounting block of the wire rope mount. 6. The suspension assembly of claim 1, wherein the swing arm is defined by a front swing arm and a rear swing arm, each of the swing arms extending downwardly and rearwardly in the closed-loop track. 7. The suspension assembly of claim 6, wherein the wire rope mount includes at least a first wire rope mount coupled between the rear swing arm and the at least one ground contact, and at least a second wire rope mount coupled between the front swing arm and the at least one ground contact. 8. A suspension assembly adapted for use with a vehicle having a chassis enclosing a drive system for rotatably driving a closed-loop track, the suspension assembly comprising at least one elongated ground contact engaged with the closed-loop track, an elongated swing arm angularly disposed in the closed-loop track, the swing arm extending 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, and a mounting arrangement 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 comprises a wire rope mount; wherein the wire rope mount includes a pair of wire rope elements mounted in side-by-side relationship between the swing arm and the at least one ground contact. 9. A kit adapted for use with a suspension assembly for a vehicle having a chassis enclosing a drive system for rotatably driving a closed-loop track, the suspension assembly including at least one elongated ground contact engaged with the closed-loop track, an elongated swing arm angularly disposed in the closed-loop track, the swing arm extending between a front end portion coupled to the chassis, and a rear end portion coupled to the at least one ground contact, the kit comprising: at least one wire rope element;a first mounting element connected to an upper end of the at least one wire rope element, and adapted to be attached to the rear end portion of the swing arm; anda second mounting element connected to a lower end of the at least one wire rope element, and adapted to be attached to the at least one ground contact;wherein the at least one wire rope element is a pair of wire rope elements. 10. The kit of claim 9, wherein the at least one wire rope element is encapsulated in an elastomeric material.
