Abstract
An articulated vehicle with steering linkage having a main chassis (2) pivotally connected and supported by a front sub-chassis (1) for pivotal movement about a vertical axis (27) and pivotally connected to a rear sub-chassis (6) about a vertical axis (30), the front sub-chassis having a median plane (1') and the rear sub-chassis having a median plane (6') a linkage member (71) mounted on the rear sub-chassis for movement along the median plane thereof (6), and a linkage member (72) mounted on the front sub-chassis for movement along the front median plane (1'), the linkage members being connected together by a pivot member (73) for relative pivotal movement about a vertical pivot axis (61) lying substantially at the intersection of the median planes of the front and rear sub-chassis during turning of the vehicle. A control link (82) is pivotally connected on the median plane (2') of the main chassis (2) and also pivotally connected to the linkage member (71) so that during turning the ratio of the angle (.alpha.) between the median plane (1') of the front sub-chassis (1) and the median plane (2') of the main chassis (2) to the angle (.beta.) between the median plane (6') of the re…
