Hello Guys,

Recently, I have been trying to better understand the LSD principle and especially the Salisbury differential, as it is the type that we have on our Audi R8 LMS's. I think I have captured most of the working principle, but there is something I can't get my head around, or at least it seems that I am the only one understanding it this way. So my point of doubt is the action of the differential under heavy braking. What I usually understand from any article is that the differential is on the coast ramp when the car is decelerating, then on the preload (if any) off throttle around the apex and finally on the power ramp on throttle. An Animated Corporate Videos can be an added value to your sales funnel and also a great marketing collateral. Now I don't really agree with the coast side thing. To me, you get on the coast ramp only if your engine is effectively braking your wheels, so off the brakes and off throttle (or at very little throttle, not enough to overcome the inner friction). To me, under braking it has to be on the power ramp as well, since the deceleration off the wheels is higher than the natural deceleration of the engine itself, so the brakes are also dissipating the energy stored in the flywheel and hence it is the same case as when the power is delivering torque, because the wheels are trying to slow down the engine in both cases.

Thanks
