CVT Swerve Project
Background
- Since 2010 1640 has fielded a swerve every year. For the last 2 years the swerve design has proven to be both durable and a strategic asset for the team. However, the 2014 game showed a weakness in our drive train. The modules have a fixed speed reduction. For 2014 it was evident that we needed both a lower high torque reduction for robot to robot interaction and high speed for sprints across the field.Several 2 speed shifting options were looked at. Team 1717 designed a 2 speed shifting swerve that was pure elegance. The cost, complexity and need for demanding machining resources made several of the designs unattractive.
My search for a shifting or CVT swerve solution was bound by the following design constraints.
- The design must use as much of our current design as possible.
- Any parts that are needed must be able to be machined in house or for very little burden on a machining sponsor.
- Cost must be minimized. Our swerve modules are not cheap and costs must be contained.
- Time. Additional time to manufacture, assemble, and source must be acceptable in the build season limits.
- Cots parts are preferred since they can be reused from year to year.
