OpenRC F1 Rear Suspension by rhoagland

Last crawled date: 3 years ago

After designing front suspension for Daniel's OpenRC F1 car I decided I had to come up with a way to make REAR suspension work. After several attempts I'm proud to say I've succeeded! Using the same battery terminal springs, "AA" this time, I was able to shoe-horn in a functional rear suspension system.
The file "Chassis Rear_Suspension" has been added to give the proper mounting holes and remove some of the original ones that were no longer needed.
I have uploaded a quick video demonstrating how it works: https://youtu.be/7EPDpDtVf3I
And a driving demo with all 3 of my designs installed on the car: https://youtu.be/g154r7Dcjas

All parts were printed in PLA with 90% infill except the motor cover, which was printed at 15% infill.
DO NOT print the file "Rear Suspension Assembled". I posted it to help with assembly.
This system uses several of the following battery terminals for springs: Keystone 5220

I started with 3 of the springs (they slide into the part called "spring holder" and ended up using 4 of them for increased support. You could use anywhere between 2 and 5 of them depending on the weight of your car and how stiff you want the suspension.
Enjoy!
