Title:
YOKE THRUST BEARING FOR PISTON/CONNECTION ROD ASSEMBLY AND METHOD FOR ASSEMBLING THE SAME
Document Type and Number:
Japanese Patent JPS60157509
Kind Code:
A
Abstract:
@ A piston and connecting rod assembly (20) comprises a one-piece yoke thrust bearing (28) disposed between the piston (26) and connecting rod (24) to provide bearing surfaces therebetween. The piston includes a pair of wrist pin bosses (34, 36) disposed therein and in spaced-apart facing relationship. The bosses have oppositely disposed faces (38, 40) with axially aligned bores (42, 44) therein, and the faces have disposed therein respective shoulder-like depressions (46, 48). The yoke thrust bearing comprises a pair of washer portions (70, 72) in abutment against respective boss faces and interconnected by a yoke element (74), and the washer portions have respective projections (80, 82) conformably received in respective depressions, thereby aligning the holes in the washers with the bores and preventing rotation of the yoke thrust bearing in the piston. One end of the connecting rod is received between the washer portions, and a wrist pin (30) is passed through the boss bores, washer portions, and the connecting rod opening (60) to thereby pivotally connect the piston and connecting rod together. A method of assembling the piston, connecting rod, wrist pin, and yoke thrust bearing is provided.
