Differential Gear

Every system Differential Gear offers it owns benefits and disadvantages, and although the more difficult systems are generally superior they have an attached price that far exceeds the simpler systems.

The downside to the system is it is extremely complicated and very expensive, and typically only used for racing/track applications for its high speed cornering potential.

Torque Vectoring Differential 940x310The yellow-colored arrow highlights the torque transfer occuring through the part, produced by the artifical resistance becoming exerted by the TVD externally wheel. This allows for higher acceleration out from the corner while the car’s turning abilitty is increased.

A Torque Vectoring Differential is capable 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 outside wheels clutch, it tricks the machine into diverting more torque through it – increasing the total amount power which can be applied and reducing the understeer experienced under acceleration out of a corner.

By continuing to use this level of resistance through the corner, as the automobile 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 grasp.

However, rather than releasing the resistance upon both wheels a TVD proceeds to activate the clutch on the outside wheel just – 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 vehicle to turn in to the corner sharper and reducing understeer.
