Abstract: Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.

Abstract: A pocket ramp for loading objects or cargo onto the floor of a vehicle and which is mounted between the longitudinally extending frame members of the vehicle. The pocket ramp assembly includes a main frame, a primary slide, a secondary slide, a lower ramp section, an upper ramp section and a latching mechanism which selectively locks the pocket ramp assembly in either of its stowed or operative positions. The main frame is fixed to the longitudinally extending frame members of the vehicle, the primary side being slidably mounted therein. The secondary slide is slidably mounted in the primary slide. The upper ramp section is pivotally mounted to the rearward end of the secondary slide and the lower ramp section is pivotally mounted to the rearward end of the upper ramp section.

Abstract: A linkage-type air suspension system for supporting either a front steer axle or a rear drive axle includes a lower structure assembly which combines the lower control rods, a transverse rod and a stabilizer control system which functions as a single structure. The transverse control system includes a pair of lower beams which have one end thereof pivotally connected to mounting brackets secured to the frame members of the vehicle by pivot bearings. The other ends of the lower beams are pivotally connected to axle and wheel supports. A transverse control is secured to and extends between the lower beams.
