Abstract
A vehicle steering and chassis oscillation system with a steering mechanism for steering the vehicle through articulation and a chassis oscillation mechanism for controlling the transverse oscillation of the chassis through pivoting of a link in the articulating mechanism of the vehicle. The oscillation control of the chassis is accomplished through pivoting of a connecting link between the axle and the chassis to tilt the axis of articulation as the connecting link is pivoted. The oscillation of the chassis through oscillation of the articulating axis provides for a means of leveling the vehicle chassis when the terrain carrying the vehicle is on an incline.
Claims14
An articulated vehicle comprising, means defining an axis of articulation including a vehicle chassis, an upper and a lower vertically spaced bearing mounted on said chassis defining an articulating axis, at least one of said bearings comprising a universally pivotal bearing, an axle means pivotally connected to the universally pivotal bearing, a link pivotally connected to the other of said bearings, a bearing pivotally connecting said link to said axle means, at least one of said bearings connected to said link comprising a universally pivotal bearing, a steering mechanism connected between said chassis and said axle means selectively pivoting said axle means relative to said chassis for steering said vehicle, a chassis oscillation control mechanism for selectively pivoting said link for controlling the relative position of said link relative to said axle means and tilting the articulating axis to control the level of said chassis relative to said axle means.
