Front and rear wheeled units (13, 14) of vehicle are connected together for articulated steering. Wheels on at least one unit are mounted for swivelling relative to the respective unit to provide kingpin steering in combination with articulation steering. A first embodiment has front and rear kingpin steering and articulation steering performed manually and independently of each other. In a second embodiment, a steering integrator cooperates with actuators (162, 163, 212, 213, 236, 237) which control at least the articulation steering and kingpin steerin...


[ We claim:] [1.] A wheeled vehicle (10) comprising: front and rear units (13,14), each unit having right hand (22, 24) and left hand (23, 25) wheels as a pair, the units being connected together to permit relative rotation therebetween about a generally vertical articulation axis (16), the front wheels (22, 23) being mounted on the front unit (13) for kingpin steering to permit rotation of each front wheel about a respective generally vertical swivel axis (154, 155) relative to the front unit; an articulation steering actuator (236, 237) cooperating wit...
