Blabbing around in this thread too eh.
Still got a bad taste in your mouth from our last conversation?
What have you done in the last few weeks? Elevated your technical skills from 0,0% to.......0,0%?
Some interesting reading: look up the patents of the company who makes the m diffs. I started reading those and they are very very interestingd. The M diff, both versions, I knew they were made by an oem, not BMW or M gmbh, but I didnt know the OEM also held the intellectual property to those components.
Very interesting because they seem to hold a lot of the patents for both gerotor actuated lsd's and the shear style actuated ones. And they have a lot of different styles for that, they were really reseaching this type of diff in the mid/late 90's, looking at maybe 50 patents or so pump clutch actuation in diff/couplings.
Its a whole bunch of patents regarding pump actuated differentials with different priciples and all filed in roughly the period '97-'01
This for example is a finished one with a disk shear pump style to actuate and published dates from '98 (one of the technical drawings from the patent):
With a single shear channel
This one (issued late 99, published 2001) has a double shear channel:
I'd love to saw the diffs in halves to make some real life crossections. looking at what shear action is used internally on what diff
So yes, I have been reading. Interesting stuff because for lots of small technical details/subfeatures are als proprietary with their own patent. (Probably all very logical to patent lawyers). Thats what I've been up to.
Still following.....Einstein?
