A differential in a rear-drive vehicle fitted with a mechanism that limits the speed and torque differences between its two outputs. This ensures that some torque is always distributed to the wheels, even when one is on a very slippery surface.
An axle differential or central differential incorporating a locking or slip-limiting mechanism to counter wheel spin. Limited slip means that some power is always applied to each of the wheels, even when one of them is on a slippery surface like ice or mud.
A differential fitted with a mechanism that limits the speed and torque differences between two outputs so torque is always distributed evenly to both wheels, even on slippery surfaces.
One designed so that, should one driven wheel attempt to rotate appreciably faster than the other, a lock comes into play to reduce the difference in speeds.
Axle gearing that allows power to be transferred to the wheel with the most traction. Similar to posi traction. (allows both power wheels to “lock up” and spin at the same time)
A differential having special friction mechanisms tending to keep both rear-axle shafts rotating at the same speed, regardless of unequal tire-to-road surface friction.
a device that allows the power to be transferred to the wheels more efficiently if they appear to be slipping or skidding
a mechanical system (not electronic/sensors like traction control) The LSD works to counter that effect, getting power to both wheels intermittently to get you some traction
A mechanical version of traction control, limiting wheel spin on an axle in two and four-wheel drives.
Unlike an open differential that provides no resistance to the differential action when the difference in rotational speed between the output shafts is small, ie. when cornering, a LSD provides increasing resistance as the difference in speed increases.
A differential that uses cone or disc clutches to lock the two separate axle shafts. This forces both driving wheels to transmit the same drive torque regardless of the traction available. It still allows differential action under normal driving conditions but improves traction in mud and snow.
A type of differential, which prevents one wheel from standing, still while the other wheel spins excessively. Often used on high-performance cars.
A differential that reduces speed differences between wheels. An LSD improves traction by preventing a slipping wheel from receiving all the engine power.
Locks both tires when accelerating in a straight line, so that not just one tire is gripping the road. Better ones even lock in turns at lower speeds. These give you better traction.
fitting one of these means that if one wheel looses grip and slips then the other wheel will still get some power. Caution: if one wheel is jacked up then the other wheel can still turn if you rotate the raised wheel.
Splits drive evenly between two drive wheels to maximize traction. Prevents one wheel from spinning while the other sits stationary. Unlike locking differential, a limited slip differential is ideal for paved roads.
In automotive applications, a limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
