[DML] gyroscopes?

["Cameron, Peter" <cameron@xxxxxxx>]

so I'm wondering who in this thread really understands suspension dynamics, and who doesn't.
 
first thing that comes to mind is the motorcycle. 
 
at speed, when one wants to turn left one turns the handlebars right. the wheels are very strong gyroscopes at speed. when one turns the handlebars to the right the effect of changing the axis of rotation of that front wheel gyroscope is to exert a torque on the frame via the axle of the wheel through the front forks. This is what overcomes the stabilizing effect of the rear wheel gyroscope and lays the motorcycle over to the left, with the front wheel scuffing slightly due to the fact it is not quite pointing in the direction the motorcycle is turning. to exit the left turn one turns the handlebars to the left (again counterintuitive) and this brings the bike back to the vertical.
 
in a car 
 
when one wants to turn left one turns the steering wheel to the left. opposite the case of the motorcycle, this causes the wheels to want to lean to the right. as the car leans to the right in the turn the desired maximum contact surface between tire and road is diminished by both car lean and tire lean. In this regard a good suspension would compensate for both leans and keep the tire flat on the road.  
 
can someone explain to us non-experts (or provide a link to a site that explains) how the suspension accomplishes this?

Even that isn't a true wishbone because there's compliance between the original LCA and the reinforcement. That needs to be a solid connection in order for it to be a true wishbone, which is the ultimate goal.

my 2 cents - original front suspension really s..ks !

Many other cars have a similar setup but built much stronger.
I think I've seen it on Fords of the 70s, but the parts were
much thicker.

But still - I love my Delo :-)
