Wheel position and suspension travel

[trose]

then the travel is how far the springs can compress above that position.

This implicit says : there is no spring-force on the lifted out wheel

But the values are:

Wheel lifted out:
static_wheelload = 0;
springforce_min > 0; travel = 0;


Wheel in defined position:
springforce_zero = f( travel=0 );
static_wheelload = f(springtravel_zero );

Wheel in upper position:
springforce_max >0; travel = max;

where:
springforce = f( travel );
if linear: springforce = f( travel ) = stiffness * travel;
--------
proposal:

travel_negative = 5 defined frome the static wheelposition downwards
travel_positive = 10 defined frome the static wheelposition upwards
springtype = linear define the type of spring normalized to the wheel
linear_stiffness = 20000 define parameter for linear type

During car initialization compute one time:
static_wheelload = f(springtravel_zero );

very interesting proposal... any more work/update on this?
