AXLE PRESSURE CONTROL SYSTEM
First Claim
1. An automated auxiliary axle deployment control system for a load-hauling vehicle having a time-variable payload and one or more fluid-operated auxiliary support axles comprising:
- (a) one or more load sensing devices for determining the payload of the vehicle in real-time and producing an output signal indicative thereof;
(b) one or more automatically operable pressure modulation valves for adjusting the force applied to deploy each of said one or more auxiliary support axles to adjust the load carrying capacity thereof;
(c) signal processing system for receiving input signals from said one or more load sensing devices and producing output control signals for operating said pressure modulation valve.

Abstract
An automated auxiliary axle deployment control system for a load-hauling vehicle having a time-variable payload and one or more fluid-operated auxiliary support axles comprising one or more load sensing devices for determining the payload distribution of the vehicle in real-time. One or more automatically operable pressure modulation valves adjusts the pressure applied to the one or more auxiliary axles to adjust the load carrying capacity thereof based on payload distribution. A signal processing system receives input signals from the one or more load sensing devices and produces output control signals for operating the pressure modulation valve(s).

20. A method of controlling the deployment of one or more auxiliary axles in a load-hauling vehicle having a time-variable payload and one or more fluid-operated auxiliary axles in which the force exerted by the one or more fluid-operated auxiliary axles is varied automatically in response to a measured real-time payload.
