The task of the crankshaft is to convert the translational motion of the pistons in the cylinders into rotational motion. Connecting rods leading to the cylinders of the connecting rods act offset with respect to the axis of rotation on the crank principle on the crankshaft. The individual cranks are arranged at 180°relative to each other in such a way as to be mutually balanced. Eight counterweights are located on opposite sides of the cranks for vibration-free operation.
In order to achieve bending strength of the crankshaft, it is fixed in five places to the cylinder block. Each crank, on which the connecting rod is fixed, rests on the right and left on the main bearing.
On the left side of the crankshaft (in the direction of travel) On vehicles with a manual gear plug, there is a flywheel on which the clutch is strengthened, which provides communication with the gearbox. On an automatic transmission, instead of a flywheel, a thin transfer washer is mounted on the crankshaft through a flange for mounting a torque converter.
At the opposite end of the crankshaft there is a toothed belt and pulley drive gear, combined with a shock absorber on a turbodiesel engine. This damper counteracts the propagation of residual vibrations, which in this case can no longer occur.
