ABSTRACT:
An articulated vehicle comprises a tractor which has a hydraulic steering gear, and a trailer connected to the tractor by a king-pin. The vehicle further includes anti-jack-knifing apparatus comprising two co-operating brake elements of a brake mechanism, one of which is secured to the tractor and the other to the trailer. The brake mechanism is actuated under the control of a hydraulic control unit responsive to the prevailing pressures in the steering gear, the arrangement being such that a predetermined, steady, anti-jack-knifing braking force is exerted by the braking mechanism when the steering gear is in its center position during rectilinear travel of the vehicle. When the steering is turned, a braking force smaller than the predetermined braking force is exerted.
