Devices for inhibiting the jack-knifing of articulated vehicles

摘要

An anti jack-knifing coupling is arranged between a vehicle and a trailer and comprises a turntable mounted on the vehicle for rotation about a vertical axis. A brake disc is secured to the turntable and brake calipers are used to prevent rotation of the turntable while the vehicle is being braked. The coupling between the vehicle and trailer is arranged so that relative articulation can only occur when the brake calipers are inoperative.
