electronic disconnnecting sway bars

**shorty943** · 25th November 2007, 09:28 PM

How does it do this Andy?

Some adjuster on the "free" (suspension) end of the bars, or is the body mounting adjustable?

I cobbled up a system for a dirt racer, that used a pair of sway bars fitted lengthwise, three fixed points and one adjustable, (the old fashioned way) to "wedge" the body for high speed speedway stuff.

ACE be similar, but somewhat more refined, than my farmyard setup.

ACE doesn't know that the vehicle is in low range - unlocking occurs at less than 4kph. But testing articulation would be slow enough plus with 1 wheel up and the other down on the same side of the vehicle, the oil flows between the front and rear rams.

I know what happens when you forget to reconnect them.
And so do most police pursuit drivers.
Holden Commodores can "self disconnect" their sway bars as well, resulting in loss of control and a crash.

Have never heard of this, please explain?? We have had a VH, VT Commodore WK Statesman and never heard of this. Or are you just talking about a fault?

It was very prevalent in the early models, SA Police banned high speed pursuits because of it. Later models are improved, but not by much.

The sway bar mounts can actually pull from the suspension arms in hard cornering. Leaving no lateral stability.
It mainly affects the "go fast boys", and the rest of us, if we get in their way.

And, the entire underbody has to be made of stiffer, thicker steel to properly cope. So I don't see "The General" spending that extra on our safety.
It's not a "bitch session" on Holden's, because the new Ford's are no better.
Truth is, there is not one Australian built car on the road, that is actually safe to drive, at the speeds they can get up to.
The standard body is just not up to it.
They're only safe at highway speeds, because highway speeds aren't really that high.

The speed limit is only about 1\3 of the modern cars top speed?
Occupants kept alive in accidents by balloons, because the vehicle is made of not much better than tinfoil?
Accidents caused by buffoons, who probably should not have a drivers license, in the first place, or don't anyway.

Give me a nice strong chassis and a well built body to bolt on top thank you.
A bit like Landy's are built.

Hi Shorty
The ACE system uses a power steer type pump.
Basically the front rear sway bars each have a hydraulic ram connecting them to the body.
In low range below a set kmh figure the system allows free oil flow,the bars have no pressure.
There are 2 sensors,1 at chassis level,1 roof level.These measure bodyroll and the computer has a speed input.
So the faster you are going and the more g force the sensors pick up the more hydraulic pressure is applied to the sawybars.
You can push a D2 with ACE around a roundabout like a race car,it works really well.Even with my hi profile 235/85 tyres I havent found the sytems limits,it is very impressive!!! Makes our Classic Rangie feel positively unsafe on the same roundabouts!!!!

I like the sentiment Shorty but I'm not sure that aluminium ranks as a well built body

something like this.

more like this:

Kinetic RFS System

Yeah, AFAIK, i didnt think that the 200LC had swaybars at all on the Kinetic Suspension versions. The RFS is the simple version, with no valving, but the complete system, (that in the 200s) can hydraulically link opposite sides of the car.

Cheers!

So not technically electronic swaybar disconnects, altho from one of the above pics, they do exist.

This is the one,
Kinetic X System

I think you are incorrect about what is fitted to the 200 series.

It is the simple version, has hyd cylinders on one side of the vehicle only and the the hyd lines connect the front and rear hyd cylinder in an X arrangement (ie top port on front to bottom port on rear, bottom port on front to top port on rear).

So, when cornering, body roll wants to extend (or retract) both hyd cylinders, but the X connection prevents them. On uneven ground, where say one front wheel goes up, the front cylinder can extend (or retract) and the rear is forced to do opposite.

There is no disconnection of the swaybars.

The 200 series is not active like ACE. It does not increase sway resistance above the normal stiffness of the sway bars as cornering roll increases.
