Abstract:
1. A suspension system for carrying a cab, the suspension system comprising: a chassis assembly comprising a first chassis section and a second chassis section; a linkage assembly comprising a first fore-aft linkage and a second fore-aft linkage for restraining movement of the first or second chassis sections, both the first and second fore-aft linkages coupled at a first end to the first chassis section and at a second end to the second chassis section; a lateral linkage for restraining rotational movement of the cab, the lateral linkage coupled laterally at a first end to the second chassis section and at a second end to the cab; and a dampener for damping motion between the cab and the chassis; wherein the distance between the first ends of the fore-aft linkages is substantially less that the distance between the second ends of the fore-aft linkages.
