The ends only of these axles move for steering, namely the part which is in the wheel and a short piece which is jointed to the fixed part of the axle. The most common form is as sketched in figs, 1 and 2, which are a side elevation and plan of one end

In these is the fixed part of the axle,  the pad upon which the spring is fixed,  the forked end of the fixed axle, and  the movable part pivoted at  in the fork on the pin, the head of which carries a lubricator at  for supplying oil or grease to the pin.
