Hi,
Motion Ratio is defined as MR=wheeltravel/springtravel.
Now I have no confusion if my pushrod/spring is perpendicular to my lower wishbone. But when it is inclined at an angle, how does it affect the motion ratio?
RCVD does not talk about inclined coil springs.
Carroll smith(Tune to Win)says it to be the wheeltravel to spring deflection ratio.
And another worksheet I found at this link:
http://performance-suspension....pensionworksheet.pdf
keeps motion ratio as the ratios of distance from the chassis pivot point of the lower wishbone, and introduces an ACF(angle correction factor) while calculating Wheel/spring rate, which RCVD and Tune to Win do not.
Is the approach followed in the worksheet right?
What I primarily wish to know is that on keeping the wheel rate fixed, will the spring rate change on inclining the spring?
Sorry if these questions seem trivial.
Thanks in Advance.
