What is the role of car connecting rods
The connecting rod is a rod-shaped zero zhidao piece that connects the piston and the crankshaft. Its function is to transmit the huge pressure of the piston to the crankshaft, so that the crankshaft makes a circular motion. The connecting rod is composed of three parts: the small end of the connecting rod, the rod body and the big end of the connecting rod. The small end of the connecting rod is integrated with the rod body, and a bronze bushing is installed in the hole, which is connected to the piston with a piston pin; the cross section of the rod body is I-shaped, which reduces the mass while ensuring the strength and rigidity, and makes it back pressure No deformation; the big end of the connecting rod is divided into two parts, the upper part is cast into the rod body, and the lower part is the rod body bearing cover, which is connected with the upper part by bolts. In order to ensure that the connecting rod head can be smoothly extracted from the cylinder, the connecting rod head has two forms: flat cut and oblique cut. In order to reduce the friction of the connecting rod journal, a layer of anti-wear alloy is poured on the bearing surface. The positioning between the connecting rod and the bearing cover is generally in the form of a stop, a tooth profile and a sleeve to ensure accurate clamping of the two.
