LSD Differential

[silente]

Hi Everybody.

I am currently working on a formula car using a Hewland Gearbox + power flow differential.

The differential is a ZF type with friction plates and ramps.

Reading the manual i learnt that this kind of differential (which is torque sensitive) has a costant value of "Locking effect" depending on plates and ramp configuration.

On the other side they said that, if you have a given Preload, then differential is locked till the difference in torque is higher than the preload.

What does it mean exaclty? that if:

(Torque slow wheel - Torque fast wheel) < Preload Torque

Than the diff is working like a rigid connections between the two wheels? so that the wheel are sharing the same torque and the same speed?

Does anybody has any experience with this kind of differentials?

Thanks!
