Greetings all,
In my quest to imagine the ultimate sportscar, I began to wonder about the following:
Certain cars are All Wheel Driven (AWD) and they do so via a Center differential delivering power to both axles. Amongst those cars, some have fixed Torque Bias/Split Ratio, which doesn't alter depending on the situation. I really would like to know how this works.
I read somewhere that these center differential are planetary geared differentials, but the details of the workings were lacking. Now I wonder; how is it possible to have different power outputs at the two output shafts of this planetary gear center differential? Also, how does it allow the two axles to turn at different speeds, like when the car is turning, or as an extreme example, drifting trough a corner while the front tires aren't being overpowered but the rear ones are? (What I mean by that is, the front tires still get the same amount of torque percentage, but are able to put the power down, while the rear tires are being blown to pieces)((And what I mean by that is, rear axle turning, say, 2 times as fast as the front axle))
I couldn't find the correct term to say some of the things I wanted to say, but that is because I'm not a native speaker and am only in the first year of Engineering college. So please excuse me :)
I'm looking forward to your answers!
