Final Design Report For Human Powered Vehicle Drivetrain Project, Derek Fromm, Luke Opitz, Michael Juri, Olivier Côté

Mechanical Engineering

The Cal Poly Human Powered Vehicle Club is building a bike to surpass 61.3 mph in 2019. The club and their mentor, George Leone, have proposed a senior project to design, build, and test the drivetrain for this year’s human powered vehicle. Research into human powered vehicles and their drivetrains has shown that the power that a rider can output and the efficiency at which the rider can pedal depend extensively on the design of the drivetrain. Despite the existence of standard bicycle drivetrain designs, the senior project team has found that the best design to meet the club’s requirements …

All Undergraduate Projects

A device is needed that can power the back wheels of R/C car and allow it to drive smoothly. This drivetrain also has to transmit power to the axles in an acceptable height range to comply with the frame and suspension. The project was supported by a team member who designed the frame and suspension. The design of this project consists of two sub-assemblies that make up the drive train assembly. The transmission assembly uses gears to convert the rotational speed from the motor to the drive shaft. The gearbox assembly also uses gears and converts the rotational speed from …
