Blackline Helical LSD's - How They Work The
Blackline helical LSD's are torque biasing, that is they distribute
torque between the wheels, loading more torque towards the wheel with
the best traction thus improving performance and driveabitily.
Especially in low grip situations. The helical gearing manages the
distribution of friction within the LSD. When torque is applied to the
helical gear system it creates force that pushes the gear into the
differential body, thus creating friction. Increases of torque,
increases the thrust force directly proprotional to the amount of
torque. This allows the Blackline LSD to cope with considerable traction
imbalance even under heavy power conditions, as would be the case on
exiting a powered up corner. But at low torque conditions the LSD can
differentiate quietly and smoothly, thus making the differential very
suitable for normal road driving. The Blackline LSD uses the popular
parallel axis helical geared configuration optimised for even load
distribution. They are designed with a torque bias of 5:1 this means
that if one wheel loses traction then the wheel with the most grip can
receive five times as much torque as the wheel that is slipping.
However, five times zero is still zero, so all these helical LSD's work
best when both wheels are 'planted' and some traction is still
available on the slipping wheel. In practice this is rarely a problem
as there is always some 'drag' on the slipping wheel, however some
drivers expertly use left foot braking to partially lock the spinning
wheel. Note - Helical LSD's work especially well when combined with modern anti-lock braking systems.
