Shaanxi kanglongsi auto parts co,ltd,as important  heavy truck suppliers in China, we have been in this industry for nearly 10 years. We export many different types of truck parts to many regions, such as South Africa, Southeast Asia, Russia, etc., especially truck crankshafts, as an important part of the engine, we have a large amount of inventory, Its advantages are good strength and rigidity, wear-resistant journal surface, uniform operation and good balance.

The truck crankshaft is connected to the engine body through the main bearing, converting the high-pressure energy of the combustion chamber into rotational power to drive the flywheel and various auxiliary components.The crankshaft plays an important role in the engine:

1. Convert the thrust of the piston connecting rod into rotational torque;

2. Convert the reciprocating linear motion of the piston into circular rotation of the crankshaft;

3. Transmit the engine torque to the transmission system through the flywheel;

4. Drive the engine's valve train and other auxiliary devices

In order to reduce the mass of the crankshaft and the centrifugal force generated during movement, the crankshaft journal is often made hollow. There is an oil hole on the surface of each journal to allow the oil to be introduced or led out to lubricate the journal surface. In order to reduce stress concentration, the connection between the main journal, crank pin and crank arm is connected by a transition arc.

It is usually used in heavy truck like SHACMAN.
