ABSTRACT:
The disclosure concerns a universal joint shaft having two coupling forks joined at a journal cross. Various embodiments of aligning apparatus selectively restrict the journal forks to adjust the angle of bend with respect to each other. In one embodiment, a tube radially outside the coupling forks and journal cross is supported on one fork and is driven by a pressure cylinder against the other fork to restrict the bending of the forks with respect to each other at the journal cross. In other embodiments, one or more piston/cylinder units are provided on one of the forks, with the piston being movable against a bearing point on the other fork for restricting the extent to which the other forks may bend. Pressure medium is delivered to the pistons through a pressure medium line controlled by a pressure maintaining valve which is shiftable for permitting pressure medium to pass to the piston/cylinder unit or to stop passing thereto.
