Title: ADJUSTMENT OF A VEHICLE FLAP, AND ADJUSTMENT METHOD
Abstract:
The invention relates to the adjustment of a vehicle flap of an agricultural vehicle, watercraft, or airplane using at least two linear cylinders, wherein each linear cylinder has at least two hydraulic chambers which can be filled with hydraulic fluid, such as a transmission oil. In such a system, the hydraulic fluids in the two hydraulic chambers can be pressurized to different degrees. The invention additionally relates to a method for controlling a vehicle flap which assumes a specific position and/or orientation on the basis of the pressure conditions in the linear cylinders. An additional load in the form of a hydraulic unit for controlling the adjustment of the flap can be designed with respect to the load switching behavior over time such that the load does not (noticeably) influence the remaining transmission control.
