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.

An articulated vehicle, comprising: first means defining a given vehicular unit having a given axis of travel; second means defining another vehicular unit having a prescribed axis of travel; one of said first and second means having a plurality of means pivotably coupling said units together, on a plurality of pivotable axes, for coincident travel of said units at a prescribed proximity therebetween; and third means, coupled to one of said units and to one coupling means of said plurality thereof, operative (a) for displacing at least one of said units to alter its axis of travel, and (b) for changing said prescribed proximity to another proximity.
