Abstract
A vehicle cab suspension unit has a foundation which is secured to an outer rail of the frame of the vehicle and pivotally connects one end of a track arm. The other end of the track arm is supported above the foundation by an air spring, and a cab support yoke is pivotally connected between the ends of the track arm so as to support and secure the cab at a position along the track arm between its ends. Shock absorbers are provided between the foundation and the cab support yoke on both sides of the track arm. A height control valve maintains the height of the suspension unit and elastomeric snubbers on the foundation provide limits to the range of travel of the unit.
