Used when other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them. |

The primary gear box is connected to the transmission via a cardan shaft. It is bogie-mounted. The final drive is that part of a power transmission system with the function of changing the direction of the power transmitted by the drive shaft through 90 degrees to the driving axles. At the same time, it provides a fixed reduction between the speed of the drive shaft and the axle driving the wheels | |
