Title:
内燃機関の連結ロッドの偏心ロッドおよびピストンからなるユニットを製造する方法
Document Type and Number:
Japanese Patent JP6641426
Kind Code:
B2
Abstract:
A method is provided for producing an assembly of an eccentric rod (15, 16) and a piston (20, 21) of a connecting rod of an internal combustion engine having an adjustable compression ratio. The method includes providing an eccentric rod (15, 16) having a first end (36, 37) for attachment to an eccentric lever of an eccentric adjusting device of the connecting rod and a second end (38, 39) for attachment to a piston (20, 21) that can be guided in a hydraulic chamber of the connecting rod. The method then includes arranging the second end (38, 39) of the eccentric rod (15, 16) in the piston (20, 21); introducing an injection-molding tool (47) into the piston (20, 21); and injection-molding a circumferentially closed retaining ring (43) between the piston (20, 21), the second end (38, 39) of the eccentric rod (15, 16) and the injection-molding tool (47).
