The steering connecting rod is a rod-like part that connects the piston to the crankshaft. Its function is to transfer the pressure from the piston to the crankshaft, so that the crankshaft makes circular motion. The connecting rod consists of three parts: connecting rod small head, rod body and connecting rod big head. Connecting rod small head and connecting rod as a whole, hole is equipped with bronze bushings, with piston pin and piston connection; rod body cross-section for the I-beam, can be in the same strength and stiffness in the case of reducing the quality, and make it under pressure without deformation; connecting rod big head is divided into two parts, the upper part of the rod and the body is cast into a single piece, the lower part of the connecting rod bearing cover, with the bolts and the upper part of the connection. In order to make the big end of the connecting rod can be smoothly extracted from the cylinder, the big end of the connecting rod has two forms of flat cut and oblique cut. The big end of the connecting rod is equipped with two semi-circular connecting rod bearings, and in order to reduce the friction of the connecting rod journal, a layer of anti-friction alloy is poured on the bearing surface. The positioning between the connecting rod and the bearing cap generally takes the form of a stopper, which is matched with the positioning sleeve according to the tooth shape in order to make both of them snap together accurately.
