  • Linkage arrangement
    Patent number: 8555746
    Abstract: A linkage arrangement is disclosed to provide an articulated machine with an arrangement that allows two frame structures to both articulate and oscillate relative to one another. The linkage arrangement includes a three point pivot arrangement with an angled link. Two of the pivots provide for articulation while two of the pivots provide for oscillation. The two pivots involved for oscillation are of lower overall height than the overall height for the two pivots providing the articulation, thereby reducing overall machine height while maintaining structural integrity.
    Type: Grant
    Filed: June 19, 2009
    Date of Patent: October 15, 2013
    Assignee: Caterpillar Inc.
