Friction clutch disable thermals

I'm trying to disable thermals on a friction clutch (I'm using it as a coupling for an electric motor and it's always engaged...it's overheating and I want to disable all thermal simulation). It seems the Lua code for the friction clutch determines whether thermals are enabled or not using the "thermalsEnabled" jBeam property, except that it defaults to true:

Code:

  local thermalsEnabled = jbeamData.thermalsEnabled or true
  device.clutchThermalsEnabledCoef = thermalsEnabled and 1 or 0

The issue is that setting it to "false" in the jBeam falls through to the default, since false is of course "falsey". I'd recommend changing the first line of that snippet to

Code:

type(jbeamData.thermalsEnabled) == "boolean" and jbeamData.thermalsEnabled or true

.

That being said, there may be a better way to couple an electric motor device to the powertrain keeping its RPM proportional to the wheel RPM that I'm not aware of, so if anyone has suggestions for that, I'm all ears.

 

I would suggest trying a torque converter that is extremely large and always has lockup enabled. It won't overheat, but I'm not sure if it will work for your purposes, and the game likes unlocking torque converters at low RPM even when they shouldn't really.

 

Make the clutch not to slip by dramatically increase lockTorque

 

Torque converter with enough high diameter and lockup set to enough low rpm and enough high torque.

With clutch you will get autoclutch and AI doing weird things I believe.

Try something like 3 meters for example for a diameter.

 

I discovered it's only when I let off the throttle super abruptly; it seems like it "jiggles" the clutch to very extreme values (between + and - 10000 Nm each frame) which I'm guessing is due to bad spring values on my wheels or suspension. I switched to a very stiff torque converter and it seems to be working a bit better. I'm still fiddling with my node weights and beam/wheel spring/damp; this is my first from-scratch vehicle so it's definitely a learning experience!

 

Check your torque reaction nodes and the movements of the hub, whes and diff, if they shake, you get this behaviour.

 

yeah use a torque converter, and a weak lockup clutch (strong as whatever is driving it), then if for whatever reason the torque load goes above that, the torque converter will just slip a bit, acting like a damper, should smooth things out a bit.
