Abstract
A wastegate actuator assembly includes a regulating rod, an arm, and a shaft. The regulating rod includes a proximate end region and a distal end region wherein the proximate end region of the regulating rod may be connected to an actuator. The arm includes a first end region and a second end region. The first end region is pivotally coupled to the distal end region of the regulating rod via a crank pin, a first cup spring, and a second cup spring wherein the first and second cup springs retain a solid lubricant substantially around the crank pin. The regulating rod may move in a linear fashion causing the arm and the shaft to rotate so as to move a wastegate cover connected to the shaft from a closed wastegate duct position (toward the wastegate duct) to an open wastegate duct position (away from the wastegate duct).
