<p>The trailer has two chassis sides and a line of axles (22 1,22 2,23 3). Each of these has a suspension with a steering arm (24). Adjacent steering arms are connected by a return steering crank (23) on a central pivot. The cranks have oval openings (25) with pins. The geometry can be varied by moving the position of the crank pivot (26) or pins. The cranks can have cross pieces coupled by longitudinal transmission rods. Active relays can be placed in the transmission rods to reduce both forces and play. These can be hydraulic, pneumatic or electric.</p> |
