Abstract

A suspension system for a cab of an off-road vehicle includes a superstructure configured to receive a cab frame. The superstructure forms a framework, the corners of which receive suspension assemblies and dampers. The suspension assemblies include one or more springs or resilient elements to resist suspension motion, and the dampers provide dampening of the motion. Lateral and longitudinal suspension motions are resisted by links between the corners of the superstructure. An anti-roll bar reduces roll. The entire suspension system may be pre-assembled and then joined to the vehicle chassis frame. The cab frame may then be placed on the suspension system. Parts of the suspension system may interface with and be housed by roll-over protective structures.
