But the suspension system, without the interlinking, does NOT respond only to changes in load applied to the wheels. It also reacts to the acceleration / deceleration forces that we are discussing in the form of diving or squatting
This statement is a little confounding but I can break it down into two parts.
1.
In a
normal car the diving and squatting are results from the jacking forces from the tyres which compress the springs - It's not the acceleration that squats the car but forces acting on the suspension, which come via the reaction from the ground through the tyres. Exapmle in squating the acceleration cause the weight to shift to the back - so the force on the rear tyres increase - the rear springs compress. I am just saying that if there were no wheels on a
Normal car - there won't be any reaction force to compress the springs.
2.
I think you could also be referring to the acceleration of the different components in the car causing them to move around relative to each other?
Like acceleration of multiple linked bodies? The mass of the wheel hub tugging on the push-rods in a quick direction change? The mass of the body pulling everything along with it in a quick direction change? That sort of reasoning? Well, It does happen but I think the suspension movements would be very small almost insignificant when compared to the Forces coming from the car and wheels.
I Imagine it like this:
Lets say you remove the wheels from a Normal suspension system. Now imagine the car somehow driving the track without touching the ground (maybe anti gravity flux capacitor?) with the suspension just hanging loose - The suspension system will not move any significant degree as the car dives, rolls and yaws around the turns.
BUT
If the system in this flying car were the mercury hydraulic system, the suspension will be moving all over the place as the car accelerates and decelerates around the track. The suspension would be moving around as if 4 ghosts were moving the wishbones.. (it would be an eerie sight) almost like this:

This shows that the response of the system does not
only comes from changes in tyre load - like a normal suspension system.
