Ok so the knuckle rotates with the longitudinal arm around the front bush because the other 3 lateral links allow it to rotate without any internal bending?
And what would be the difference between this and a classic 4 link suspension, so replacing the longitudinal link knuckle side fixing with...
Are there any parasitic rates present with wheel travel? I imagine the torsional around global Y is soft on that front bush?
@GregLocock since you mentioned it, how is the snubbing distance determined? Is it essentialy a knee-point between impact forces and braking forces? So for low stiffness...
Thank you both for your inputs very useful as you clearly have experience with these.
So the blade I can imagine being very flexible in the global Y (translation) and also around the Z (rotation) and X (rotation) axes, but a lot stiffer around Y (rotation) axis. Wouldn't this Y rotation induce...
Below is a Mercedes rear multi-link (EQA I believe). I say it's unusual as it's clearly a multi-link with two lower links, one upper and a longitudinal, however the longitudinal seems to be very thin piece of sheet metal that's fixed on the knuckle side.
First of all, does this not constraint...
Brian,
The big picture is trying to understand why increasing castor increases tie rod loads (or does it..?), and in general I use a double wishbone suspension to build this understanding.
Ultimately, does it depend on how much the mechanical trail changes by compared to how much the kingpin...
But the above is true only if the angle change without moving the steering axis. I'm not sure how castor is adjusted on cars usually, but if we increased it by moving only the LBJ, that would move the steering axis too, surely? So I guess the steering axis wouldn't move if we increased caster by...
Your second paragraph just made me realise that, so thank you.
So according to my equation, I can see how castor increases tie rod/rack forces for a rack thats in front of the kingpin axis . As castor increases, the kingpin moment goes up, and, the distance from the tie rod to axis reduces...
Hi,
I'm trying to understand how forces work through the steering system and their effects on the dynamics of the vehicle.
My understanding is that the lateral force at the tyre induces a mount around the kingpin axis location (and if we only consider lateral forces, then only the castor...
