In theory the output from a torque converter drive looks like this:

The output from a three stage torque converter such as the Voith L630 or a four speed gearbox driving through a single stage torque converter such as the Mekydro transmission can be represented in OR by using tractive force curves.

The theoretical output from a mechanical gearbox looks like this:


There is a representation of mechanical gears in OR that can be used to model a manual or automatic gearbox.

Many transmissions combine both a torque converter and mechanical gears. The theoretical output looks like this:


Lindasyts has posted some data for a real example (The Voith T312r) here gearbox feature

I would like to get some more information about real transmission systems and their behaviour. If people have data they would like to share or links to information please post them here.

Some older systems names include Smith-Lysholm, Twin Disc, GM Allison and Rolls Royce as well as the various systems by Voith. (Possibly there might be published railway test data available in Germany about the Mekydro system and the various Voith systems.) Bringing things more up to date it would be interesting to know more about the ZF Ecomat gearbox and the Voith DIWA systems.
