Abstract: Air damping systems for lift axles are described herein. In some embodiments, lift axle systems configured in accordance with the present technology can include one or more air springs for carrying vehicle sprung mass (“load springs”) and one or more air springs (or, for example, air cylinders) for raising the lift axle (“lift springs”). One or more air lines can be connected between the load springs and the lift springs so that, in operation, compression and extension of the load springs in response to axle movement causes pressurized air to flow back and forth between the load springs and the lift springs. As a result, the lift springs provide an additional volume to receive the pressurized air and provide an opposing spring force to the suspension. Additionally, in some embodiments the air line or lines extending between the load springs and the lift springs can include an air flow restriction and/or other air damping feature.

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.
