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