Abstract
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.
Claims7
A suspension apparatus for a track-type vehicle comprising a main frame, pivot shaft means fixedly secured to and transversely outwardly extending from said main frame, a pair of laterally spaced track frame means pivotally connected through said pivot shaft means to either side of said main frame, respectively, an equalizer bar pivotally connected to said main frame and extending transversely between said pair of track frame means, characterized in that said apparatus is provided between said track frame means and said equalizer bar with a pair of stress-relieved mounting means, each comprising forward and rearward mountings fixedly secured to the inner vertical surface of said track frame means;
- a shaft having at the rearward end thereof a spherical part pivotally accommodated through a spherical bush within said rearward mounting and having at the forward end thereof a block part loosely housed within said forward mounting;
- a resilient pad member interposed between said block part of the shaft and the inside of said forward mounting;
- and spherical bushing means pivotally connected to each end of said equalizer bar and slidably mounted on a substantially intermediate portion of said shaft.
