The force on the crankshaft is transferred to the piston first the petrol pump pumps the fuel from the tank to the atomiser, where it gets atomised and then burns to produce force! This force pushes the pistons. The piston then sends the force through the piston rod to the crankshaft, the crankshaft rotates and sends the force to the gearbox, so the car goes! In the whole of which the piston rod plays a role in the transmission of force! If the load on the piston rod is not very large, use 45# steel. If the load is quite large, use 40Cr. All have to be tempered.
1, trauma. Other institutions or foreign objects cause damage to the surface of the piston rod, the piston rod to do reciprocating motion, and other institutions interference generated;
2, the piston rod is subject to large external radial force. Strictly speaking, the piston rod is strictly prohibited to withstand radial force, when the piston rod is subjected to radial force, friction between the piston rod and the guide sleeve to produce strains;
3, cylinder quality problems. Concentricity is not up to standard, the inner and outer circular concentricity of the guide sleeve, piston concentricity of the inner and outer circles, piston rod body and piston mounting surface concentricity, concentricity of the piston rod and cylinder moving axis, etc., beyond the prescribed standards may cause the piston rod or even the cylinder cylinder strains;
4, cylinder installation problems. Various forms of cylinders if the installation does not meet the cylinder concentricity, verticality, straightness and other requirements may also cause damage to the cylinder;
5, mechanical equipment reasons. Mechanical equipment design or poor manufacturing, resulting in inevitable damage to the cylinder.
