ARTICULATED VEHICLE COUPLING GEAR Russian patent published in 1997 - IPC

FIELD: transport engineering; device for coupling single-track prime-mover and double-track trailer. SUBSTANCE: coupling gear has brackets 1 and 2 rigidly secured on each member and interconnected by clamps 5 and 7 and connecting member with horizontal and vertical pins, 3 and 4, respectively. Mechanism to provide position tilting of single-track tractor at cornering and ensure stability of tractor at straight ahead running and at parking place is arranged between lugs of clamp 7.
