Title: L-shaped tow bar for articulated lorries - is rotated by hydraulic ram acting on extension to reduce turning circle
IPC: B62D13/00
Filed: 1975-04-29
Abstract: The tow bar (3a) between the tractor unit (1) and trailer (2) hinges about central pivots (4,5) on the tractor and trailer. An additional horizontally perpendicular extension (3b) to the tow bar is connected by an end pivot (6) to an hydraulic ram (8), which is fixed to the trailer chassis (9). Displacement of the ram is controlled by the vehicle hydraulic circuit and causes the L-shaped tow bar to rotate from its median position.
