  • Diffuser plate for connecting a rigid structure to a flexible structure and machine using same
    Patent number: 7681919
    Abstract: A machine having a ground engaging element includes a first rigid metallic structure, a second metallic structure that is flexible with respect to the first rigid metallic structure, and a diffuser plate having a stress carrying region located between a first end and a second end. The first end has a rigid attachment to the first metallic structure, and the second end has a rigid attachment to the second metallic structure. The stress carrying region is flexible with respect to the attachments. A stress produced from a flexing of the second metallic structure relative to the first metallic structure is concentrated within the stress carrying region of the diffuser plate instead of at a weld location.
