The dual-mass flywheel replaces the classic flywheel in such way that it is divided into two masses (the primary mass and the secondary mass), which are jointed together by means of a flexible interconnection. This kind of the flywheel solution ena

Noise and vibration are concomitant work processes, all machinery possibly different production machines or vehicles. Vibration and noise of the working environment can not be completely eliminated, but they can be reduced to an acceptable value. O

The aim of gearbox lubrication is to reduce wear on the sides of the teeth, increase of the efficiency by reducing friction as well as dissipating the heat generated by friction. Lubrication of gearboxes is a discontinuous process, that means, during
