Minimum articulation angles for vehicle couplings
|
|
Reference Number: R55-12-06
|
|
UN R55 does not include provisions for minimum articulation angles of couplings. However, couplings may be damaged if a vehicle combination takes a narrow curve or other maneuver that exceeds the coupling design. In order to prevent coupling failures, this proposal suggests minimum articulation requirements based partly upon ISO 1726-1 and 11407 for drawbar and fifth wheel couplings.
