Blackline VW 02A Transmission (push in flanges) Helical LSD.

Description

Suitable for:- Golf Mk3/4 Corrado Jetta Vento Helical LSD Advantages:- Equal rotational speed to both wheels Torque distributed according to traction Minimal service requirements - no clutches Quick response compared to viscous LSDs Soft and progressive engagement, low noise Easy to control PTO and drift Gears and body manufactured from 8620 alloy steel Direct replacement in standard differential Blackline Helical LSDs - How They Work The Blackline helical LSDs are torque biased, that is, they distribute torque between the wheels, loading more torque to the wheel with the best traction, improving performance and handling. 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, force is created that pushes the gear into the differential body, creating friction. Increase in torque increases thrust which is directly proportional to the amount of torque. This allows the Blackline LSD to handle significant traction imbalances even under severe power conditions, as would be the case when exiting a high-powered corner. But at low torque conditions, the LSD can differentiate quietly and smoothly, making the differential very suitable for normal road driving. The Blackline LSD uses the popular parallel shaft helical gear configuration optimized for even load distribution. They are designed with a torque bias of 5:1, meaning that if one wheel loses grip, 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 LSDs work best when both wheels are "planted" and there is still some grip available on the slipping wheel. In practice, this is rarely a problem because there is always some "drag" on the slipping wheel, but some drivers skillfully use the left foot brake to partially block the spinning wheel. Note - Helical LSDs work especially well in conjunction with modern anti-lock braking systems.
