摘要

A self-steering railway truck having interconnected steering arms (163, 164)) associated wifth the axled wheelsets (160, 162; 161, 162) and having mechanism (181-188) for yieldingly resisting yawing motion of the wheelsets including at least two devices (see Figure 7) at least one (202) of which provides a relatively high rate of increase of resistance per unit of deflection in the initial portion of the yaw motion and at least another of which (190) provides a relatively low rate of increase of resistance per unit of deflection in a portion of the motion beyond said initial portion.
