Tricycle - Power only the rear wheel

Discussion in 'Racer Physics and Technical' started by ZkidMarkZ, Jul 10, 2013.

  1. 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
     
  2. powered=0
     
  3. 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
    }

    NEVER GIVE UP!!

    do you have....

    wheels=3

    in the head of your car.ini?
     
  5. yes I do. Are you sure it should be possible to do?

    it is...but the way i got it a longe time agoo was with a "faked" 4 wheeler....
     
  7. ok. I did that as well now :) Maybe someone finds a solution in the future!

    yep maybe...
     
  9. 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

  10. The first solution seem to work! Thanks a lot :) Now on to the biggest mystery of them all.. Getting the Materials on the 3D-model correct ;)
