Preparation for Full Assembly and Production

Image
Following our presentation, there were a few issues that needed to be addressed. The drawings needed small alterations based on the materials we will be using. Spacing was changed slightly due to the sheet metal being in customary units rather than the metric we designed for (0.25 in vs 3 mm). Another change was moving the lower passive wheels down slightly as to accommodate the change in track sizing. With these changes, the designs are ready for other teams to incorporate their parts into the bogey. The files have been available for the last few weeks but now the track CAD is complete as well and ready for assembly.

Last Minute Details and Modifications

After producing our shop drawings for the sheet metal components of the drive bogie, we were notified by the motor team that there was a clearance issue with the new track width. The in-hub motors would be overhanging by about 5 mm on each side. To rectify this, I have been planning out an adjustment to our CAD models to remove 10-12 mm of width on the drive bogie. Due to this being only a slight adjustment that doesn't affect all of our components, we are still moving forward on sourcing materials and preparing for production. We will be utilizing the central shop of the engineering department as well as the Makers' Space for fabrication. Below is one of the shop drawing that remains unchanged by our adjustments:
