ABSTRACT:
In the exemplary embodiment shown, the vehicle is a drum-type asphalt compactor having a pair of drum-compactor units coupled together for steering articulation. The units have prescribed axes of travel, and are coupled together for travel with the axes in line with, transverse to, or offset from, each other. A hydraulic piston and cylinder actuator displaces a coupling link, which is commonly, pivotedly joined to the units, to bring the travel axes into a transverse disposition. Another link or lock bar, freely engageable and disengageable from one of the units, is used also to couple the units together for the purpose of cooperating with the actuator and coupling link to bring the travel axes into an offset, parallelism.
