Differentials

[KITT3000]

Is it possible to add the "onlyRWD" profile?? I have a tractor that does not have all-wheel drive. Earlier, using DriveControl, I had to have 3 lines from the differentials in the XML file:

Unfortunately, after the AWD was switched on, the front wheels were driven (although they should not be because the entire transmission to the rear is set). I would like to completely disable the AWD and the differential lock of the front wheels so that only the rear differential can be blocked. Is it possible or must be how it is??

[Mogli12]

I think a tractor with RWD should have only one differential. But I am not sure.

[KITT3000]

I tried it, but then you can not block the differential.

[Mogli12]

Ok, this is something I can add.

[KITT3000]

I have edited the differentials in the tractor XML file and look like this:

<differentials>
        <!-- <differential torqueRatio="0.0" maxSpeedRatio="0.0" wheelIndex1="0" wheelIndex2="1" /> <!-- front left-right -->
        <differential torqueRatio="0.5" maxSpeedRatio="1.3" wheelIndex1="2" wheelIndex2="3" /> <!-- back left-right -->
        <!-- <differential torqueRatio="1.0" maxSpeedRatio="1.0" differentialIndex1="0" differentialIndex2="1" /> <!-- front-back -->
</differentials>

Unfortunately, the gearbox in this tractor is not working and there is such an error:

E:/Gry/CDP Games/modyFS17/MP_UserB4D/FS17_UrsusC360/UrsusC360.i3d (153.78) ms
Error 3 loading gearboxMogliLoader: E:/Gry/CDP Games/modyFS17/MP_UserB4D/FS17_GearboxAddon/gearboxMogli.lua:2617: attempt to index a nil value

PS. GB v3.0.2.0

[Mogli12]

Oh, sorry. I forgot that I already started with the differentials but then worked on #338.

[KITT3000]

Ok, I'm waiting for an update.

[Mogli12]

Please check v3.1 b21.

[KITT3000]

I checked the latest version and such errors appeared:

Error 3: E:/Gry/CDP Games/modyFS17/MP_UserB4D/FS17_GearboxAddon/gearboxMogli.lua:3153: attempt to index a nil value
Error 3: E:/Gry/CDP Games/modyFS17/MP_UserB4D/FS17_GearboxAddon/gearboxMogli.lua:3110: attempt to index local 'diff' (a nil value)

[Mogli12]

Sorry, but I did not have time to prepare a test. Is v3.1 b22 better?

[KITT3000]

Ok, no errors and it works correctly. But it would be possible to block AWD and front differential lock (I mean displaying icons and text on HUD). And add a profile to the configuration (or explain how to add it to the configuration in 'gearboxAddonConfig.xml'), so that RWD tractors are really RWD (most have 3 differentials, just like basic tractors in FS).

Fixed for me too with Lelyjuno150 many many, many thank.

Hi,

Please set up 3 differentials in your vehicle with torque and speed ratio corresponding to RWD; example:

<differentials>    
  <differential torqueRatio="0.5" maxSpeedRatio="1000" wheelIndex1="0" wheelIndex2="1"/>
  <!-- front left-right -->
  <differential torqueRatio="0.5" maxSpeedRatio="1.8" wheelIndex1="2" wheelIndex2="3"/>
  <!-- back left-right -->
  <differential torqueRatio="0.0" maxSpeedRatio="1000" differentialIndex1="0" differentialIndex2="1"/>
  <!-- front-back -->
</differentials>

Now add the following below tag <gearboxMogli...> or <transmission...> in gearboxAddonConfig.xml:

<differentials>
  <front torqueRatio="-1"/>
  <middle torqueRatio="-1"/>
  <back torqueRatio="0.5"/>
</differentials>

Does this work?

[KITT3000]

Works, but not completely correctly. Switching AWD - RWD does not work (as it should be), blocking the front differential also does not work (as it should be), but I do not know why the front right wheel is driven all the time.

Edit: Now I have applied your differential values in the tractor's XML file and there is something strange. Only the front wheels are driven instead of the rear ones (AWD and blocking differentials does not work).

Hello, Mogli did you fix it ? Regards.

[Mogli12]

Please check v3.1 build 77.

[KITT3000]

@Mogli12 Works fine (although it would be good to block icons and entry in HUD from 4WD and front differential lock).

I still have a question if the mod has only 1 line with a differential in XML, and I would like to add to it the ability to lock the back differential (it requires 3 lines with differentials), what attributes must I have in the lines in config?

[Mogli12]

Gearbox supports 4wd (3 lines in differentials) and 2wd (1 line in differentials). You can have different differential configurations, which you can attach to the wheel configuration.

[KITT3000]

@Mogli12 i have

 <differentials>
        <!-- <differential torqueRatio="0.5" maxSpeedRatio="1000" wheelIndex1="0" wheelIndex2="1"/> --> <!-- front left-right -->
        <differential torqueRatio="0.5" maxSpeedRatio="1.8" wheelIndex1="2" wheelIndex2="3"/> <!-- back left-right -->
        <!-- <differential torqueRatio="0.0" maxSpeedRatio="1000" differentialIndex1="0" differentialIndex2="1"/> --> <!-- front-back --> 
    </differentials>

and

<differentials>
                <front torqueRatio="-1"/>
                <middle torqueRatio="-1"/>
                <back torqueRatio="0.5"/>
            </differentials>

or

<differentials>
                <!-- <front torqueRatio="-1"/> -->
                <!-- <middle torqueRatio="-1"/> -->
                <back torqueRatio="0.5"/>
            </differentials>

and unfortunately it is not possible to switch the rear differential lock

[Mogli12]

Ah, the default handling is not yet there for 2wd. Please add manual4wd="true" as attribute to tag <gearboxMogli ... or <transmission .... I will change the default with the next version.

[KITT3000]

I added this attribute to <gearboxMogli but it did not change anything in relation to 1 liner in the vehicle XML and both options in the config.

[Mogli12]

Please add a screen shot. Which version are you using?

[KITT3000]

Unfortunately, today I can not do it anymore because I am already at work, tomorrow I will be ss. I am using the b77 version.

[Mogli12]

It works for the IHC 644 mr

[KITT3000]

It work if you have 3 lines differentials in XML if is only 1 is not work. eg. http://farming-simulator.com/mod.php?lang=pl&country=pl&mod_id=103316&title=fs2017

[Mogli12]

It is fixed with v3.1 build 79.

[KITT3000]

It work perfect :)
