<p>The invention relates to an arrangement and a method for automatic support wheel load relief on a powered vehicle (1). The invention also relates to a powered vehicle. The vehicle incorporates a support wheel arrangement (3) which includes at least one support wheel (5) capable of being applied to a ground surface (2) by an applied pressure, and a main wheel arrangement (6) which includes at least one main wheel (8). The automatic support wheel load relief arrangement includes a device (15) designed to alter the pressure applied to said support wheel(s), and a sensor arrangement (12, 13) designed to detect the value of a parameter which depends on the rotation speed of said main wheels relative to the vehicle's travel speed. The automatic support wheel load relief arrangement further incorporates a control unit (14) designed to automatically control said actuating device (15) in response to said parameter.</p> |
