Railroad vehicle truck with single wheelset |
摘要 |
A railroad vehicle truck having a single wheelset includes a pair of spaced side frames. The side frames are joined into a rigid unit by a pair of transversely positioned crossbars. The crossbars are positioned one each on each side of the wheelset which has its axle ends journaled in bearings carried in turn in a pedestal jaw centrally formed in each side frame. Projecting inwardly from each end of the side frames is a bracket which forms part of a set of upper pivot connections with an upper end of a swing arm. A laterally positioned crosstie assembly is joined through a pair of spaced end caps with a lower end of each swing arm to form a set of lower pivot connections. Each crosstie assembly end cap has a pair of spring cups containing a set of springs which operatively support a body of the railroad vehicle thereabove.
