초록

A suspension apparatus for a track-type vehicle comprises a main frame having a pair of laterally spaced track frames pivotally mounted on either side thereof through a pair of pivot shafts fixedly connected to either side thereof. The forward portions of the track frames are connected to opposite ends of an equalizer bar extending transversely therebetween through a pair of stress-relieved mounting devices into which lateral and vertical displacements of the track frames and the equalizer bar are absorbed so as to prevent “toe-in”of the track frames.
