Design
Our team designs our mechanical CVT from scratch, but we have limited means of controlled testing. Prior to the dyno, we would simply run acceleration times in the parking lot to tune the CVT, which works, but it is time consuming and difficult to justify if other things on the car need attention. The image on the right is the inital packaging and frame design (which was done in Siemens NX). I would have liked to have all components on one axis, but we wanted an elevated work plane for end users and because doing so makes packaging and component swapping much easier. Tentative plan is to run a No. 50 chain between the gearbox output and the motor, which was specced according to the max power calculated at the gearbox output, with a built in FoS of 1.4.
