Week 11: Drive Bogie V4

This week, I headed the redesign of the drive bogie. It was a huge relief that Wayside Power confirmed that they could power the two wheel drive system. That allowed me to simplify the designs and throw out the concepts I have for articulation of the wheels for turning. I took cues from Futran on their lower clamping wheel system, designing a rigid set of wheels that do not actively hug the bottom of the rail. These wheels aid in keeping the bogie on the tracks and prevent the drive wheels from losing traction with the rails. Additionally, the two sets of wheels are offset to prevent twisting on the rails.

This should mark the end of design for the drive bogie. From here, I will send off the CAD to my teammates for a full set of FEA tests. From there, I will alter the design as needed. I am confident in the design and feel that it may only require a few supports to be ready to build.
