How Do Kaaz Differentials Work?

Posted by Sam 22/09/2016 0 Comment(s) Technical Info,

There has been a lot written and a lot talked about the LSD and its function. KAAZ-Sports has been developing Limited Slip Differentials for many many years and over this time they have learned all of the best practices in LSD design and performance. Below explains how Kaaz LSD work and the benefits using a Kaaz LSD. Much of this has been translated from the Japanese catalogs and also form time that members of Limited-Slip.com have spent with Kaaz Engineers both in the UK and in Japan.

A standard differential in your car is known as a "free" differential. This means that each wheel is free to rotate on its own. Should one wheel spin or go onto a muddy surface all the power is transferred to the wheel in the mud because as it is the easiest route for the transfer of power. The down side of this is that you lose traction and forward momentum. This is not an ideal situation in a competition event as you are looking for forward traction at much as possible.

Inside a Kaaz limited slip differential or LSD are a combination of special flexible plates and a pin in-between them. Then as the car accelerates the pin is pushed between the plates moving them out and in turn "locking the diff", with a diff locked if the wheel goes onto a muddy surface then the plates work to put the power to the wheel that is not slipping. Also when you decelerate the pin moves to a new position and again presses the plates to give you good control under braking.

There are two options from Kaaz on the type of LSD:

 

KAAZ 2 Way LSD

For a rear wheel drive car the best option is a 2.0 Way LSD

In a rear wheel drive car on acceleration and cornering the pin pushes the plates out and locks the diff giving good traction to both wheels. Then should one wheel spin the power will be transferred to the wheel that is not spinning. Should both wheels spin under very hard acceleration say when performing wheel spin start or performing a doughnut or drifting the car then power is distributed equally to both wheels.

With all this going on inside you are able to perform these driving enjoyments. The car is more stable going into a corner and you fill find you have faster exiting speeds. On some applications a 1.5 Way Kaaz LSD is also an option. The 2 Way is also a lot more beneficial for the high speed track driving, drifting and other car sports.

 

KAAZ 1.5 Way LSD

For a front wheel drive car the best option is a Kaaz 1.5 Way LSD, also for the suitable motorsport driving.

Just like the Kaaz 2 Way LSD upon acceleration the pin moves the plates out and locks the diff and in turn limits the wheel spin or slip. But upon deceleration the pin moves to a new position but only applies ½ the force as if it applied the full force the car would be unstable under braking and deceleration.

When acceleration around a corner you will "feel" the diff working for you and through the steering wheel you will feel the diff pulling you around the corner. This can be a strange feeling, but you will find that you also now have much higher exiting speeds.

As well as 1.5 and 2 way Kaaz LSD, Kaaz also offer the Kaaz  Solid Type. The Kaaz Solid Type uses RS plates and offer a much better reaction time when a LSD "Locks" up. Take some time to read about the Kaaz Solid Type LSD.

 

KAAZ Solid Type LSD

A Kaaz Solid Type LSD is best suited drifting as is faster reaction time, better power transfer and better grip characteristics benefit this type of sport.

Above is a short example of the difference in a Kaaz Std Type and a Kaaz Solid Type Limited Slip Diff.

 

Nissan, R200

This LSD has 20 clutch plates compared to 8 in an standard type LSD and has a 250% faster reaction time

Toyota IS200

This LSD has 16 clutch plates compared to 12 in an standard type LSD and has a 133% faster reaction time

Mitsubishi Lancer Evolution

This LSD has 20 clutch plates compared to 12 in an standard type LSD and has a 167% faster reaction time

Mazda RX7

This LSD has 12 clutch plates compared to 8 in an standard type LSD and has a 150% faster reaction time.
