Every system offers it owns Differential Gear benefits and disadvantages, and although the more complicated systems are generally superior they have an attached cost that far exceeds the simpler systems.
The downside to the system is it is very complicated and very expensive, and typically only used for racing/track applications because of its high speed cornering potential.
Torque Vectoring Differential 940x310The yellowish arrow highlights the torque transfer occuring through the part, generated by the artifical level of resistance getting exerted by the TVD externally wheel. This enables for higher acceleration out of the corner as the car’s turning abilitty is certainly increased.
A Torque Vectoring Differential is with the capacity of channelling 100% of the obtainable torque through a single wheel when needed in the most extreme of circumstances.
With the TVD exerting more level of resistance onto the exterior wheels clutch, it tricks the system into diverting more torque through it – increasing the amount power that can be applied and reducing the understeer experienced under acceleration out of a corner.
By continuing to use this resistance through the part, as the vehicle passes the apex and begins to accelerate out it will continue to override a normal multiway-LSD – which would again interpret the faster moving outside wheel as slipping and divert torque during acceleration to the within wheel, which it perceives as having more grip.
However, instead of releasing the resistance upon both tires a TVD proceeds to activate the clutch externally wheel only – increasing the resistance experienced by that wheel and making the machine channel more torque through it. This imbalance of power to the outside encourages the automobile to turn into the part sharper and reducing understeer.
