Tricycle - Power only the rear wheel

ZkidMarkZ · Jul 10, 2013

Hi,
As the title says I'm making a tricycle and I am trying to make the power from the engine to only drive the rear wheel, "wheel2" (there are two wheels in the front). I have set output0 = 2 but the engine still sends power to the front-left wheel as well..
Can anyone help?
Thx in advance

powered=0

I tried adding that that to the wheels:

Code:

wheel0~wheel_common
{
  powered=0
  ...
}
wheel1~wheel_common
{
  powered=0
  ...
}

but i still drives at least the left front wheel as well.
My differentials look like this:

Code:

differential
{
  type=4
  inertia=0.05
  locking_coeff=100
  output0=2
}
differentials
{
  count=0
  diff0
  {
    type=4
    inertia=0.05
    locking_coeff=100
    output0=2
    friction=0
  }
}

And my suspension looks like this:

Code:

susp_front~susp_default
{
  z=0.9254
  roll_center
  {
    x=0
    y=0
    z=0
  }
}
susp_rear~susp_default
{
  z=-0.4755
  k=100000
  bump_rate=10000
  rebound_rate=10000
  roll_center
  {
    x=0
    y=0
    z=0
  }
}
susp0~susp_front
{
  y=0.0287
  x=0.2695
}
susp1~susp_front
{
  y=0.0287
  x=-0.2695
}
susp2~susp_rear
{
  y=0.0287
  x=0
}

do you have....

wheels=3

in the head of your car.ini?

ZkidMarkZ · Jul 10, 2013

yes I do. Are you sure it should be possible to do?

Alexander Knoll · Jul 11, 2013

it is...but the way i got it a longe time agoo was with a "faked" 4 wheeler....

ZkidMarkZ · Jul 11, 2013

ok. I did that as well now

Maybe someone finds a solution in the future!

Alexander Knoll · Jul 11, 2013

yep maybe...

I've never tried this, but did you try output0=2 and output1=2?

A weird other solution is to create the 4th wheel/suspension but have it floating up near the car CofG, give it zero mass, zero inertia etc, and then run a locked differential.

Hmmm
