## The project of the motorcycle’s power transmission system

### Piotr Jankowski

#### Abstract

The main subject of this thesis is creating a project of the power transmission system for the WSK – 125 motorcycle. It assumes changing the chain transmission for its belt equivalent, the assembly of which does not require any interference with other componentries of the motor-cycle. Before proceeding to the designing process, some research had been done of the presently available solutions for the power transmissions in the currently produced motorcycles. One has analysed the advantages and disadvantages of the belt and chain transmission as well as the drive transition with the Cardan’s shaft and the 2WD drive. The power transmission and the turning moment in the electrical single-track vehicles have also been discussed.The design part contains a series of calculations, which result in the obtained values of the geometry of the belt transmission, such as: diameters and number of tooth pulleys, width and length of the drive belt. The visualization of the designed system was done with the programme Autodesk Inventor Professional 2017. Using this programme allowed to verify the previous calculations and to adjusting the power transmission system to the existing engine and the gearbox. In the construction some aluminium components were used to decrease the weight of the system. The final part of the thesis consists of: the visualisation of the design equipped with a short description of each element of the system and some conclusions. The attachments include an assumption drawing of the system as well as the chosen assem-bling drawings.
