VARIABLE GEOMETRY LINKAGE CONFIGURATION

摘要

A variable geometry linkage configuration for use between a support structure and suspended body comprises a link member having first and second ends, a first pivotal interconnection for pivotally interconnecting the first end of the link member with a support plate for rotation about a support pivot axis of rotation. A leve r member is provided which has a longitudinal axis and first and second ends. A second pivotal interconnection for pivotally interconnecting the first end of th e lever member with an impact plate for rotation about a main pivot axis of rotation. A shock pivot is mounted to the lever member and is adapted to connect an end of a shock absorber to the lever member for rotation about a shock pivot axis of rotation. A third pivotal interconnection is provided for pivotally interconnecting the lever memb er to the link member for rotation about a lever pivot axis of rotation. An improved variable geometry linkage is provided in which at least one of the pivotal interconnections comprises a universal pivot joint for articulation of the link member with respect to the support plate and/or the lever member about mutually perpendicular axes to accommodate pitch and roll between the impact plate and th e support plate.
