Patent ID: 7753612

Claim:
An assembly comprising: a bell crank fork including opposing first and second external faces, and first and second lugs, each of the first and second lugs including a lug bore, the lug bore of the first lug being aligned with the lug bore of the second lug along an assembly axis; wherein the first lug includes an indentation on an external face of the first lug, the indentation extending from a free end of the first lug a predetermined distance beyond the lug bore of the first lug and forming a substantially planar facet with the first external face of the bell crank fork, the substantially planar facet being perpendicular to a longitudinal plane of symmetry of the bell crank fork and parallel to the assembly axis; a swiveling device which swivels on the bell crank fork about the assembly axis, said swiveling device including an internal ring having a ring bore and an external ring rotatably disposed on the internal ring, the internal ring including a first transverse ring face and a second transverse ring face which are perpendicular to an axis of the ring bore along the assembly axis, each of the first transverse ring face and the second transverse ring face including diametrically opposed steps recessed into the respective transverse ring face; an assembly rod which is unthreaded, the assembly rod including a rod head which includes a substantially planar facet which is parallel to a longitudinal direction of the assembly rod along the assembly axis, a first shaft portion of the assembly rod being disposed closer to the rod head than a second shaft portion of the assembly rod; a first bushing disposed in the lug bore of the first lug, a body of the first bushing being press fit in the lug bore of the first lug to prevent rotation of the first bushing relative to the bell crank fork; and a second bushing disposed in the lug bore of the second lug; wherein each of the first and second bushings includes a shoulder with an end face which bears against the internal ring and an opposing face, opposite the shoulder, which bears against the first lug and the second lug, respectively; wherein each of the first and second bushings includes diametrically opposed lugs which protrude from the end face of the shoulder, each of the bushing lugs being matingly engaged with a respective one of the steps of the internal ring to prevent rotation of the internal ring relative to the first and second bushings; wherein said assembly rod passes successively through the lug bore of the first fork lug, the ring bore, and the lug bore of the second fork lug such that the planar facet of the rod head is parallel with and abuts the planar facet of the indentation in the first fork lug to prevent translation and rotation of the assembly rod relative to the bell crank fork about the assembly axis; and wherein the second shaft portion of the assembly rod is press fit in an internal diameter of the second bushing to prevent rotation of the assembly rod relative to the second bushing.
