ABSTRACT:
Apparatus for limiting relative tilting between a tractor unit and a trailer unit of an articulated vehicle comprising a horizontal hitch pivot fixed to the tractor to permit relative tilting movement between the tractor and trailer units. A pair of right and left stationary stop members are each fixed to the tractor frame and spaced from the pivot device. Two pairs of movable upper and lower stop engaging members are fixedly connected to the horizontal pivot device to contact opposite sides of each stationary stop member to limit relative tilting movement between the tractor and trailer. During the relative tilting between the units, one of the movable upper stop engaging members contacts the upper surface of one of the stationary stop members and simultaneously therewith the opposite movable lower stop engaging members contacts the lower surface of the opposite stationary stop members to evenly distribute stresses exerted on the components when limiting the tilt between the tractor and trailer units.
