Week of 9/26/2018

The highlight of last week and this week was preparing for Presentation 1. I work on the guide arm of the bogie. Dan recommends in his final report from Spring 2018 that the guide arm should be spring loaded. The main benefits it to reduces wear on wheels of bogie and vibrations endured by the whole bogie. The main purpose of the guide arm is to guide the bogie around curved sections of the track. For the presentation, I presented two idea of how plan to make the wheels of the guide arm spring loaded. I have attached both the designs below. Also, the team is responsible  providing the Motor team with mounting points for the hub motor axles. I did some research on bicycle hub motors, and came across a peer-review articles that suggests a new method of mounting hub motors to the forks of the bicycle. The gist of the article is to use an elongated axles that threads into the sleave pressed in the motor; on the other side, a cap then tightens into the axle. A cut-out of the article is also provided below.
