Improved Suspension

Filed under: Machining,Robots — Bob @ 7:35 pm

During the construction of my outdoor robot I found that the original RC truck suspension was too soft, not able to really stand up to the added weight of the new structure. I found new, stiffer springs for the shocks, however these new springs were larger than the originals and would not correctly fit.

I needed to create some retainers that would fit the existing shocks but also securely hold the new springs so they could not slip off. I ended up using some blue nylon plastic rod and turned it on the lathe to make retainer rings. In the picture above, you can see these retainers at each end of the spring.
