Fluid bearing

Hi,

I got a YouTube channel where I release some animations on automotive engineering: Thomas Schwenke

Now, I want to create an animation about bearings. However, I don't get the fluid bearing quite right - at least that's what I'm thinking.

As far as I know, crankshafts (in engines) have hydrodynamic fluid bearings. If I look at the fluid wedge (e.g. https://upload.wikimedia.org/wikipedia/commons/a/a5/Gleitlager(dyn+stat).jpg), I don't understand how the shaft can be kept at the center position in case of fast acceleration and sudden braking of the car as well as driving over (e.g.) damaged roads that will vigorously shake the car (and therefore the shaft?).

As far as I know, a bearing with two inlet ports is not used.

So, anyone can tell me how it's done?

Best wishes,
Thomas
