Abstract
1302681 Steering articulated vehicles; fifth wheel couplings B E DINES 19 April 1971 [2 Jan 1970] 330/70 Headings B7H and B7T An articulated vehicle comprises a semitrailer 1 connected to a tractor 2 by a fifth wheel coupling assembly 6 disposed between the front and rear wheels 4, 5 of the tractor, and means controllable from the driving cab 3 of the tractor for turning the semi-trailer relative to the tractor to steer the vehicle. All the tractor wheels 4, 5 may be driven and the tractor may be steered by differential braking when operating independently of the semi-trailer. The fifth wheel coupling assembly 6 comprises a plate 8 pivotally supported by a support plate 9 which is mounted on a hub 12 and carries a cam 10 supported on rollers 13 and shaped to provide a self-centring action under the weight of the semi-trailer. A chain 15 engaging a sprocket on the hub 12 is connected to hydraulic rams 16 which are controlled by steering mechanism in the cab 2, and may be operated at a pressure which is varied with the load on the semitrailer. A block 19 is provided on a coupling plate 17 on the semi-trailer for engagement with the king-pin entry recess in the rear of the fifth wheel-plate 8. In another embodiment, instead of rotating the fifth wheel assembly as a whole, a separate steering member is rotatably mounted on the fifth wheel assembly for turning the semitrailer.
