This thesis examines the various types of transmissions which allow to seamlessly change gears without interrupting the transfer of a motor's power output. In particular, it elaborates on the advantages and disadvantages each design presents for a FormulaStudent/SAE vehicle. Furthermore, the thesis explores the selection of gear ratios and simulates acceleration parameters in order to achieve the best possible dynamic behavior. What is more, the thesis presents a concrete implementation of a transmission for the Husqvarna FE 501 motorcycle redesigned with the Zeroshift mechanism. It includes a fundamental change in the operation of the clutch as well as a gear stress analysis. Last but not least, the TU Brno Racing team incorporated the main conclusions of the thesis into the team's vehicle in order to improve the team's standings in international races.

This thesis deals with no delay gear shifting. The first part is devoted to theoretical introduction. The next part describes comprehensive approach to vehicle dynamics, the choice of gear ratios, the use of reverse engineering to model the interior of the gear housing and the actual structural design of the internal components and strength analysis. Moreover, this work should fill the gap in the available literature which is publicly accessible.
