Transport trailer load balancing suspension and steering systems
First Claim
1. A steering system for at least one axle of a multi-axle transport trailer, the steering system comprising:
- a hydraulic control valve that distributes fluid to one or more cylinders configured to turn wheels on either end of the at least one axle;
a sensing device that monitors turning movement of the wheels, wherein when the trailer is moved in reverse the sensing device prompts a switch to send a signal to the hydraulic control valve to cause the cylinders to turn or straighten the wheels based on the turning movement.
