Abstract: A compound steering mechanism for a vehicle includes a steering axle, steerable wheels mounted on the lateral ends of the axle for pivoting movement relative to the axle, and a mechanism for mounting the axle to the vehicle body to permit pivotal movement relative to the vehicle body about two orthogonal axes, the first axis being generally vertical and offset from the line of contact between the steerable wheels and the ground and the second axis extending generally fore-aft of the vehicle body. The mechanism for mounting the steering axle on the vehicle body is formed with an intermediate member, termed a skate, that is mounted on the vehicle body for pivoting about the said fore-aft axis and having a gimbal mount for supporting the steering axle in a manner to allow pivoting of the latter about the vertical axis.
