Re: Was ist das?????.....tiny CVT!!!!!!

Wow, I sure hoped we didn't make any of the wrong (same) assumption as 217. I hope we can get this tested soon, but since we are mostly manufacturing everthing ourselves it has been a slow process. Two items in Paul's post I don't understand though: 1) The reaction force is from the Sun and ext. gear pinion and the motors which are attached to a housing and chassis. 2) How can you have the same output torque at different speed ratios - where is the energy going? To this second question it could go into backdriving the other motor. But we designed the gearing so that they should output the same torque at stall. We are also planning to connect a current sensor on the motors to detect when they are backdriven.

If it all goes bad - we do have a backup transmission ready (but it's so darn heavy!!)
