Abstract
  • The purpose of this project was to design the 2016 combustion car drivetrain for Global Formula Racing (GFR). The goal of this project was to improve upon the 2015 drivetrain design by reducing complexity, weight, and maintenance time. To reduce complexity the spool was changed to a one piece system and the drivetrain inserts were changed to a simpler design. These changes were able to reduce weight and the complexity of machining by making the designs more simple. The drivetrain mounting system had its complexity reduced by moving to a eccentric chain tensioning design. This was chosen because it reduced the time to adjust the chain and reduced the overall part count of the system. The major issues that occurred during this project had to do with the manufacturing of the drivetrain mounts. Since there were issues finding sponsors to make the mounts they had to be made in house. This required learning edgecam and the cnc machining process to be able to manufacture them. The machining of the mounts took a tremendous amount of time and this made it difficult for their to be enough time during the manufacturing phase to make two complete sets. The result of this project is a finished and functioning drivetrain for the 2016 combustion car. The car has been through numerous test days and the drivetrain has worked exactly as expected. So far there have been no issues with the performance or maintenance of the system. Next year the designer of the drivetrain should focus on further improvement of the spool design and reducing the manufacturing time of the whole system. Furthermore, a heavy emphasis should be put on finding sponsors with large machining capabilities to help manufacture the drivetrain system.
