<p>An improved articulated connector or coupler in which the connection between the male connecting member (24) and female connecting member (22) via a king pin (30) is provided with an elastomeric bushing (44) housed in the male connecting member. The bushing has an outer metallic ring (46), and inner metallic ring (48), and a middle ring (50) of elastomeric material, by which a coupling free of uncontrolled slack is achieved and by which all normal draft and buffing, as well as train-action and angling, forces, are damped and partially absorbed by the elastomeric ring (50). For excessive loads, in order to protect the elastomeric ring (50), over solid metal-to-metal stops (52) are provided which shunt the force transmittal from the elastomeric ring (50) to metal stop-surfaces (52). The king pin (30) is also frusto-conical in shape at the intermediate portion (30") thereof passing through the bushing (44) of the male connecting member (24), which bushing (44) has a similarly-shaped frusto-conical passageway.</p> |
