Design of gearbox for electric vehicles
Košík, Matej ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with designing electric vehicle gearbox. Gearbox should serve as virtual replacement for actual transmission of VW ID.3 EV. Designed gearbox has two gears. In the first section there is an extensive search processed of drivetrain and transmission of battery electric vehicles. Next section contains choice of transmission concept and analyses solving of individual structural nodes – gear wheels, band breaks (components that engage individual gears), carriers, shaft, bearing. In the conclusion of diploma thesis, the two-gear planetary transmission is evaluated.

Possibility of Replacing the Formula Student Chain Secondary Transmission by Gearwheels
Košík, Matej ; Janoušek, Michal (referee) ; Ramík, Pavel (advisor)
This thesis deals with research of possibilities of replacing secondary chain drive by gear with purpose to integrate secondary gear and differential into engine block of vehicle Formula Student. It compares single draft designs. The first part of thesis consists of an introduction to Formula Student competition and a research of parts of traction conversion unit and of the formula Dragon 9 internal combustion engine. In the second part multiple draft designs of secondary gearing were performed and then checked by strength calculations. The best version of replacing secondary gearing is bevel gear. It is complex issue to design a gear suitable for application in racing car, so I suggest further possibilities of optimisation the bevel gear.
