<p>#CMT# #/CMT# The piston (1) has a piston pin retainer for fixing a piston pin (2) and provided with a stopper (5) and a circlip (4), which is formed as a locking ring or retaining ring. The stopper is designed as a radially inwardly extending collar, where the piston pin rests with an axial front end (6) on the collar. The stopper and an inwardly open circumferential groove (7) are arranged at two ends of a hub hole (3) respectively, where the piston pin is retained in the hub hole. Diameter (d1) of the hub hole is larger than diameter (d2) of a hub (9). #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a piston. #CMT#USE : #/CMT# Piston for a combustion engine. #CMT#ADVANTAGE : #/CMT# The piston pin retainer fixes the piston pin in the piston such that a lateral slipping of the piston pin can be prevented in a reliable manner. The piston pin retainer is provided with the stopper and the circlip that is formed as the locking ring or retaining ring such that a need for additional circlip can be avoided, thus reducing wall thickness at the hub hole while significantly reducing weight, and hence enabling inexpensive and simple manufacture of the piston pin retainer. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a piston with an assigned piston pin. d1 : Hub hole diameter d2 : Hub diameter 1 : Piston 2 : Piston pin 3 : Hub hole 4 : Circlip 5 : Stopper 6 : Axial front end of piston pin 7 : Inwardly open circumferential groove 9 : Hub #CMT#METALLURGY : #/CMT# The piston is made of steel or light metal such as aluminum alloy.</p> |
