Abstract

A system to simultaneously adjust a wheel track axle width and a steering angle of an agricultural vehicle made of: an at least two variable axle assemblies, each one of the variable axle assemblies connected to a wheel set of the agricultural vehicle is provided. During the wheel track axle adjustment process of a variable wheel track axle machine the angle of each wheel is “toed-in” or toed-our depending on wheel track extension or retraction. When the wheel track axle of the machine is being extended, all wheels are commanded to “toe-out” 3 degrees to aid in the extension and reduce external forces on the wheel and axle system. When the wheel track axle of the machine is being retracted, all wheels are commanded to “toe-out” 3 degrees to aid in the retraction and reduce external forces on the wheel and axle system. Once the wheel track axle adjustment is complete all wheels return to 0 degrees for normal operation.

• B62D 6/00 - Arrangements for automatically controlling steering depending on driving conditions sensed and responded to, e.g. control circuits
• B60B 35/10 - Dead axles, i.e. not transmitting torque adjustable for varying track
• B60B 35/00 - Axle unitsParts thereof
• B62D 5/18 - Power-assisted or power-driven steering fluid, i.e. using a pressurised fluid for most or all the force required for steering a vehicle characterised by power transmitting means
