An apparatus for connecting a trailer 20 to a vehicle for traction. The device comprises a vehicle-trailer coupling and a switchable yaw pivot 2. The vehicle-trailer coupling comprises a vehicle coupling 1a and a trailer coupling 1b, and has a vertical centerline X. The switchable yaw pivot 2 can be switched between a locking position and an unlocking position. In the unlocked position, a portion 3 of the device is allowed to move about the switchable yaw pivot 2 relative to the remaining portion of the device in order to align the vehicle coupling 1a with the trailer coupling 1b to assist the coupling. In the locked position, after coupling and once the vehicle is aligned with the trailer, said portion 3 of the device is not allowed to move about the switchable yaw pivot 2 relative to the rest of the device. When the switchable yaw pivot is locked, the relative yaw movement between the vehicle and the trailer can only occur around the virtual yaw pivot Y.

    一种用于将拖车20连接至车辆以进行牵引的装置。该装置包括车辆‑拖车联接器和可切换偏航枢轴2。车辆‑拖车联接器包括车辆联接器1a和拖车联接器1b,并且具有竖直中心线X。可切换偏航枢轴2能够在锁定位置与解锁位置之间切换。在解锁位置,允许装置的一部分3绕着可切换偏航枢轴2相对于装置的其余部分运动,以便使车辆联接器1a与拖车联接器1b对齐以辅助联接。在锁定位置,在联接之后并且一旦车辆与拖车对齐,不允许装置的所述一部分3绕着可切换偏航枢轴2相对于装置的其余部分运动。当可切换偏航枢轴被锁定时,车辆与拖车之间的相对偏航运动只能绕着虚拟偏航枢轴Y进行。
