Steerable wheel axle arrangement and method of controlling a steerable wheel axle arrangement

A steerable wheel axle arrangement for a vehicle, the steerable wheel axle arrangement being connectable to a pair of wheels and comprising:

• a steering linkage connectable to the pair of wheels;
• a cylinder comprising a fluidly controlled piston movable within the cylinder, the fluidly controlled piston connected to the steering linkage and movable between:
• a first end portion of the cylinder adapted to be in fluid communication with a first wheel brake of the vehicle for controlling braking of a first wheel of the pair of wheels;
• a second end portion of the cylinder adapted to be in fluid communication with a second wheel brake of the vehicle for controlling braking of a second wheel of the pair of wheels;
• and
• a fluidly controlled brake actuator, comprising:
• a first fluidly controlled brake actuator adapted to be in fluid communication with the first wheel brake of the vehicle and the first end portion of the cylinder;
• and
• a second fluidly controlled brake actuator adapted to be in fluid communication with the second wheel brake of the vehicle and the second end portion of the cylinder;
• wherein, upon actuation of the first fluidly controlled brake actuator, fluid flows to the first wheel brake and the first end of the cylinder to move the fluidly controlled piston away from the first wheel to increase a first yaw moment caused by the first wheel brake;
• wherein, upon actuation of the second fluidly controlled brake actuator, fluid flows to the second wheel brake and the second end of the cylinder to move the fluidly controlled piston away from the second wheel to increase a second yaw moment caused by the second wheel brake.
