There's lifted truck in this somewhere lol. That's not how the final drive works on a HMMWV, is it? I've only seen the outside housing of that glorious unit that gives the truck about a foot of vertical extension in the space of only a few inches. Well, neat, and innovative, and I'm out of the industrial life.
The HMMWV uses portal axles, which is what you were referring to. They don’t use the Schmidt coupling, but just a gear ratio with idler gears to have the input and output rotate in the same direction. My guess is that it’s simpler and more reliable that way. Correct me if I’m wrong, however Edit: After looking around I’ve seen that they don’t actually have idlers
Guten Abend sehr geehrte Damen und Herren der Fa. Schmidt-Kupplungen, ich habe eine Frage: Kann man Ihr Kupplungssystem auch als Antriebskomponente für KFZ hernehmen anstatt der heute üblichen Portalachse? MfG Danishjo Dariush
Mag ich bezweifeln. Die ankommenden Drehmomente des Antriebsstrangs im Kfz und die zu bewegende Masse sind für diese Kupplung sicherlich nur dann verkraftbar, wenn die Materialstärken der einzelnen Hebel entsprechend dimensioniert und die unzähligen Gleitlager ausreichend geschmiert sind. Darüber hinaus benötigt diese Art Kupplung einen klaren Vektor, über welchen sie sich bewegen darf und wohin nicht, was Führungsschienen nötig macht. Da sind die üblichen Zahnräder und Gelenkkupplungen kleiner, leichter, wartungsärmer und belastbarer.
Only a single layer would operate at a fixed distance, tracing out a circle rather than being able to move. 2 layers gives you an extra degree of freedom, letting the distance change too. A third gets you nothing extra. Edit: Actually you probably can't. 3 linkages would be under-constrained. While 2 links can get to any point, the angles are fixed. With 3 links the angles are not fixed, and the intermediate layers would be able to move. Fix 2 points on a triangle with fixed sides and the last point stays still. If there are more points they can wave about. This movement would damage the mechanism.
old school gears can't provide the variable axis offset this mechanism does. chain is actually more complicated as it has more parts, more moving joints and more points of failure. not to mention you need a form of tensioner when the two axes are near each other (just like how a derailleur tightens the bike chain when you're in small cogs).
@@HaterBob By creating a planetary gearbox. Let the outer gear circulate around the inner. I.e. move it along a circular segment. Thus you raise and lower that outer gear's axis. It solves this particular problem (lifting an axis vs the sheet), but if you are semantically picky, there is still no change in inter-axis offset.
