Stainless Steel/45 Steel 40Cr Automobile Connecting Rods
The connecting rod of a car is a key component in the engine and transmission system. Its main function is to connect the piston and crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft, thereby driving the car. The following is a detailed description of automotive connecting rod products:
- Structure: Automobile connecting rods are usually composed of three parts: the connecting rod small head, the rod body, and the connecting rod large head. The small end of the connecting rod is connected to the piston through a piston pin, the rod body is the main part of the connecting rod, and the large end of the connecting rod is connected to the crankshaft. Among them, the connecting rod big end is equipped with two semi-circular connecting rod bearings inside to reduce friction on the shaft neck.
- Function: The main function of the connecting rod is to transmit the power generated by the reciprocating motion of the piston in the cylinder to the crankshaft, so that the crankshaft can continue to rotate, and then transmit the power to the driving wheels of the car through the transmission device. At the same time, the connecting rod also bears enormous pressure and inertial force from the piston, so its material and structural design must be very sturdy and precise.
Machining Precision:
The requirements for dimensional accuracy, shape accuracy and positional accuracy of the connecting rod are very high. Precise processing technology needs to be adopted to ensure its quality.
Machining Process:
After the automobile connecting rod is finely processed by a Swiss-type lathe, in order to improve the fatigue strength and service life of the connecting rod, its surface needs to be specially treated, such as shot peening, carburizing and quenching, etc. The connecting rod needs to undergo heat treatment during the manufacturing process to improve its mechanical properties and wear resistance. Quenching and tempering treatment is one of the commonly used heat treatment methods. The combined process of quenching and high-temperature tempering is used to improve the strength and toughness of the connecting rod.
Product Application:
The main uses of automobile connecting rods are: connection and transmission. It converts the reciprocating motion of the piston into the rotational motion of the crankshaft, ensuring the normal operation of the engine and improving driving stability and comfort. The material and use of automobile connecting rods are important factors that cannot be ignored in automobile design and manufacturing. Choosing the appropriate connecting rod material and design is of great significance for improving the performance, efficiency and safety of automobiles.
