Wheel loader slip

[Fracking]

Hi, the Claas Torion 956 Sinus is basically undrivable on fields. The skid steerer L318 has similar issues. Smaller articulated loaders also have high slippage on fields. The Schäffer 9660 T-2 is okish. The heavier Torions 1511 and 1914 are drivable. I think there is an issue with the weight distribution. The front axle has almost no load in the debug screen. Perhaps there could be a "fake" load/friction for wheels that are on the ground but report nearly 0 load/weight.

Best regards

hi, as a workaround, I set up the minimal radius of affected wheels to 0.6 = works for bigger machines. But, you are right and there is a problem. This is the question for @900hasse

Thanks, I´ll try that min radius setting. I´ve also tinkered with the frictionCoeff and raised it by a lot. It fixes the sliding trailer. Base game grip is a bit too high, but REA_wheels grip is a bit too low (I think). I don´t own farming gear, but I look at RL setups (vids) and then guess the grip.

happy testing :-) if are you interested, I can send you my version, which was heavy tuned and tested more than a year. I'm looking for share values close as possible to IRL feeling

[Fracking]

Sure, I´d like to try it.

Glad to share, maybe for inspiration also for @900hasse :) REAwheels.lua.txt

Someone noted that the calculation for rolling resistance might be wrong but time is limited and I have not looked any deeper into the issue.

perhaps you can send it as PR?

Derived from this and other infos I gathered here and there, this is my outcome: REAwheels.lua.txt

hi @s4t4n, I'm not sure, because this is only my opinion. It's not exactly updated, only - maybe - version? With full respect to @900hasse and his work. My values aren't based on any real values or observations, only on my feelings in the game.

[Gordon-Dry]

I pulled that back, I just recognized that those values are good on the field but very bad on tarmac. I go back to my file as I used it for weeks, only with those changes I derived from "here and there": REAwheels.lua.txt

[DrewCZ]

Hi @Gordon-Dry - it's up to you of course. But, what I saw IRL, was that the "arrowed" tractor tires were a bit slippery on the tarmac. Try comparing it with "road" or "offroad" tires.

[Gordon-Dry]

Well, when those are not full of mud, just a small amount of soil and the conditions are dry, a little slip would be okay for the first meters, but not even reaching 20 kph (on a 40 kph tractor) with 90% slip on all 4 wheels, moving that way for dozens of meters is a little much. Especially when the soil remains are between the "arrows" of the profile, but the part that has ground contact is clearly rubber.

[Gordon-Dry]

After testing for some more time I came to the conclusion that a slight edit of my old version works for me. REAwheels.lua.txt
