Jiangling 2.4 Expansion broken connecting rod assembly

Classification: Expanding Connecting Rod

The small end of the connecting rod is used to install the piston pin to connect the piston. The rod body is usually made into "I" or "H" section to reduce the mass on the premise of meeting the strength and stiffness requirements. The connecting rod big end is connected with the connecting rod journal of the crankshaft. Generally, it is made into a separate type. The half cut with the rod body is called the connecting rod cap, and the two are connected together by connecting rod bolts.

The connection between piston pin and piston pin seat hole and connecting rod small end bushing hole adopts full floating and semi floating connection. The full floating connection is adopted, and the piston pin can rotate freely in the hole; The semi floating connection is adopted, and the pin and the small end of the connecting rod are interference fit, so there is no relative rotation during operation; The clearance fit is between the pin and the piston pin seat hole.
Connecting rod
The role of the connecting rod is to transmit the force borne by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotary motion of the crankshaft.
Connecting rod is composed of connecting rod body, connecting rod cap, connecting rod bolt, connecting rod bearing bush and other parts. Connecting rod body and connecting rod cap are divided into connecting rod small end, connecting rod body and connecting rod big end.
