ICR for Leaf Spring Suspension
(OP)
Hi guys,
Trying to calculate Anti-Dive for rear leaf spring suspension. But not able to locate the ICR for leaf spring.
Any info on this would be much appreciated.
Thanks

RE: ICR for Leaf Spring Suspension
I am not sure how you can calculate/find out Anti dive geometry for leaf spring suspension. In most of the books including Gillespie, inof is given on ICR for links and independent suspension but not for leaf spring.
I am trying to locate pivot point for leaf spring suspension so that I can get ratio of er/dr for Aniti-dive.
And thanks for the reply

You are asking a question that has no /general/ accurate answer, but there is a 'good enough' answer, depending on your definitions.

RE: ICR for Leaf Spring Suspension
ICR is instanteneous center of rotation. Actually I want to find out the pivot point for the leaf spring so that I can calculate what is the Anti-lift of rear suspension during breaking due to load transfer.
Hopefully this should give you a clear idea.
And sorry for the confusion
Thanks Again

You aren't confusing /me/, you are using words that are poorly defined.

RE: ICR for Leaf Spring Suspension
I have plot the wheel travel geometry using "3 point method" for leaf spring. Also later I found out in Milliken that the pivot point length of the spring is approx 3/8*Lenght of the spring. They are coming close.
Also one more question, How much Anti-lift generally one should target for rear leaf spring suspension for SUV kind of vehicle.
Again thanks for the input.
Regards,
Dipak
