Hi all, here's a video I did where I use a 10 level torque gadget I created to run some torque experiments to help improve my automatic gearbox designs. Hope you find it interesting.

 

Very interesting.

But how well does it work in MOCs?

Thank you for doing these experiments!

You are developing lots of theoretical and practical knowledge about autos! I hope it allows you to make some refined practical designs. (I gave up on smooth, multi-speed mechanical autos in favor of electronically controlled ones, using PU)

I love your work on automatic gearboxes. I usually just use a stepless automatic transmission like the one detailed here.

Hi Horologist. Thanks for sending that link! That's an awesome looking device by Nico71 - I think I am going to try to build it...love the tachometers - very clever.

Hello, what you bring and the way you bring it is very new and clever !

This video is perfect !

However, the content may be difficult to follow to whom is not very good with english, which should be improved by just a short list of the objectives of your video shown in the topic on eurobrick or as summary at the begin of the video.

Ayyy my suspicions were right - gearboxes should always operate at high speed and low torque

Yes, this is the ideal, I think, and not only because of shift points; even if you are controlling gears manually, low torque means that the driving rings are far less likely to pop out of a well-reinforced structure. Of course, in larger gearboxes, you may need quite a bit of torque at the input simply to rotate all the dead gears.
