Adams axle

An Adam axis is used to store a wheelset of a rail vehicle laterally movable. The axis was invented by William Bridges Adams and 1865 patented. The axis can swing like a salmon bites laterally and thereby set radially. Instead of a drawbar an Adam axis is guided by laterally sliding on a circular arc journal bearings with slanted sliding plates, the center of the arc in the pivot of the (imaginary) drawbar is. This construction means plain bearings is indeed complex, but requires less space than a drawbar. Adam Saxony carry parts of the vehicle mass, however, drive the vehicle less well than more elaborate constructions. With a resetting device can improve the running properties. For leading axles of fast-moving locomotives, this design is less suitable. Were used as precursors in Saxony Adam not too fast-moving steam and early electric locomotives and especially as a trailing axles of a Tender locomotives. The advantage here is that under the ashtray no drawbar frame must be installed.
