Pseudo four-leg semi-automatic vehicle leveling system

摘要

A pseudo four-leg leveling system for a vehicle, such as a recreational vehicle or the like, includes four jacks in the form of hydraulic cylinders mounted to the vehicle frame. Two jacks are located adjacent to the rear the vehicle and two jacks are located adjacent the front of the vehicle. A manually operated control mechanism is located within the vehicle, and a power system interposed between the control mechanism and the jacks supplies hydraulic fluid to extend and retract the jacks thereby adjusting the attitude of the vehicle relative to level. Hydraulic fluid supplied to the rear jacks is controlled independently from the other jacks. The front jacks are in fluid communication with each other, and hydraulic fluid supplied to the front jacks is controlled independently of the hydraulic fluid supplied to the rear jacks. The invention minimizes frame twist when leveling the vehicle.
