Abstract
A piston pin carries out an eccentric coupling of connecting rod and crank connected with the driving shaft. The piston pin is shaped like a cylinder, has two cuts disposed orthogonally to the axis of the piston pin. The cuts form three sectors. The two external sectors correspond to the connection with the crank and the internal sector is coupled to the connecting rod.
Claims8
A piston pin (1) for connecting a connecting rod (10) to a crank-drive shaft (8,9) and for forming an eccentric connecting rod system, the piston pin comprising:
- two cuts (2, 3) which are disposed orthogonally to an axis of the piston pin and form three sectors (13, 14, 15) all having the same diameter of which two sections are lateral sectors (13, 15) forming an eccentric connection with the crank-driving shaft (8, 9) and including between the lateral sections a central sector (14) forming an eccentric connection with the connecting rod (10) and including a joint section (17) formed as one piece between said lateral sectors (13, 15) and said central sector (14).
