Paper Title
Design of Ball Lock Multi-Speed Transmission System

The SAE Mini Baja team requires a custom, multispeed transmission for their vehicle. Concurrent engineering with the Baja design team created a working model. The overall purpose of this project was to fabricate a fully functional three speed [10:1 and 7:1 and 6:1] transmission for a 10 HP vehicle. The product was designed using decision matrices and house of quality. Then, it was drawn up on SolidWorks and a finite element analysis was done on the shafts in order to optimize the design. Lastly, some of the designs were sent to a manufacturer and the rest were machined by the team using Tech�s facilities. The finished product was integrated into the vehicle that will race in future.
