What are the Types of Limited-Slip Differentials?

Types of Limited-Slip Differentials:

There are many types of limited-slip differentials. Except for the sake of simplicity, we will divide them into four primary types.


Clutch Limited-Slip Differential:

A clutch differential (also called a mechanical clutch differential or clutch-type differential) is the most typical sort of LSD. They use clutch plates to transfer torque as needed by providing axle lock during a loss of traction.

Depending on how it operates, these may be a one-way, two-way, or one-and-a-half-way LSD. One-way LSDs work only under acceleration. Two-way LSDs also work during deceleration. A one-and-a-half-way LSD works under acceleration and, to a lesser degree, during deceleration.


Viscous Coupling Limited-Slip Differential:

A viscous coupling LSD (also called a viscous LSD or VLSD) uses gear fluid to realize the identical effects as a clutch-based LSD. However, they tend to be smoother than other LSDs at low speeds. They’re also simpler in design and frequently more efficient overall. A downside is that the gear fluid will heat up with extended use, lowering its effectiveness.


Geared and Torsen Differentials:

Instead of using clutches or fluid, geared differentials use worm gears and spur gears to distribute torque to the wheels. The Torsen type is the most typical and well-known geared differential. They don’t require the maximum amount of maintenance as clutch-type LSDs. They also offer better efficiency. However, they’re going to typically be noisier and have more vibrations.


Electronic Limited-Slip Differential:

Electronic LSDs (or torque-vectoring differentials) are the foremost expensive and sophisticated. The advantages are that they are often proactive instead of reactive. They’re programmed to try exactly what they have to at a given time.

This means they will give power to the skin wheel when exiting a corner, which is that the wheel with less grip. This helps with sharper cornering and reducing understeer. Electronic LSDs are perhaps most prominently seen in Lexus vehicles.
