description: The 4WD Drivetrain Design and Analysis team developed detailed design and analysis tools for the drivetrain of the Mini-Baja student competition car. a drivetrain necessary for achieving the goal to meet the 4WD requirements of the 2020 SAE Baja Competition. The team’s original plan was to create a single-reduction gearbox that will transfer power from the Gaged Constant Velocity Transmission (CVT) system to two Polaris differentials at the front and rear of the car. After several design iterations, it was determined that there was not adequate spacing to achieve a short, competitive frame in conjunction with a gearbox. Based on our current findings, we are recommending a chain drive for its adaptability and versatility instead of a gearbox to achieve the desired intermediate speed reduction. Due to the ongoing global pandemic, the 2020 Baja team is no longer able to build the car which modified the original project goals to include developing detailed performance simulations to determine appropriate gear ratio vs. speed, detailed design recommendations and suggested manufacturing plans for next year’s team to continuing the project and build the car. Future teams will be able to easily learn the aspects of implementing a 4WD and gearcase system design by reviewing our detailed calculators and associated user guides showing how to properly manufacture the gearcase using the tools available as well as purchase the correct gears and components required for success.
