K'nex Differential Working Model

This a fully functional differential, working in the same way as those on vehicles. It is mostly a demo model, and would need a very large K'nex car to use it. However, you can modify it to your heart's content, if you wish!

The only thing a regular K'nex set may not have is the black Y clips and the large yellow gear. Other than that, the pieces are standard.

This is the supporting structure. Just follow the notes.

These represent the wheels and axles of the vehicle and make the model easier to operate and visualize.

This is the main component of a differential, and allows the wheels to spin at different speeds.

This is the "drive shaft." You could replace the crank with a drill to represent high speed.

While cranking, note that the wheels and the central gearbox spin together, but the small yellow gears stay still. Slow one wheel and the yellow gears will begin to spin, allowing the other wheel to continue at the same speed. Have fun experimenting!
