Nico, when implementing this into your car, how will it work? because you have the input (motor), the output (would normally be the rear axle), and the "resistor", in the video that is what you are holding in your hand. The resistor has to be attached to the rear to work.
@35Racerboy No, in fact the resistor is the rear axle, when the car goes on hill, the rear axle has a resistance and the gearbox switch the ratio because of the torque. I have tested the CVT on a vehicle and it does't work well. If the model is to big, the pins constantly slips and the vehicle doesnt move. If I put a hard fricition switch, the CVT will never switch the ratio. I think this type of friction gearbox is only suitable for light moc.
Looks fantastic! Have you seen the work Jorrien and I had done a while back? He has his own CVT models and research on his site, as well as a few models of my own.
Friction based CVTs work well for their purpose- Change in load applied to the output can select a lower ratio, but very much work is lost due to friction! That, and there is no real reasonable manual selection of ratios- Your work is very nice, you should try a more complex model!
Very nice! I will try to build it using the instructions now up on your site. Maybe I'll build my ole' off-road truck that I had and implement this into it. I'll have to do some testing :P
Also put some kind of pad with a rack and scroll gear to apply steady pressure to the output shaft instead of wearing out your fingers! You should hook up one of your LPEs to that and make your own Dynamometer!
@PhantomStrain Of course, the friction affects directly the maximun torque available and the linearity of the variation. With a smooth friction, the torque is not high (low torque makes 1/5), with high friction pin or many pin or pin affect multiplication (it is the case here), the available torque is higher. This model was developed and set up for a 1kg car maximun. The zblj's one has not enough available torque for my implementation. Regards
@Zblj1987 have a close look to the video and the description Jernej. I mention that it is a modified version based on your work. What is the point ? do you think I am a thief ? Not at all, be sure.
@nico71240 I don't think he was accusing you of being a theif, rather he is complimenting you on the work you did on his gearbox. I agree with him as well, it shows very clearly how a CVT mechanism works. Good job!
so it is more reactive
awesome creation & vid btw.

Very nice. Does the friction of the 8 tooth gear adversely effect the efficiency of the transmission at all?
