differentiallås

A differential lock, often called a diff lock, is a mechanism that can be engaged to lock the differential of a vehicle. A standard differential allows wheels on the same axle to rotate at different speeds, which is essential for smooth turning. However, in off-road or slippery conditions, if one wheel loses traction, the standard differential will allow it to spin freely while the other wheel, which may have grip, receives no power.

When a differential lock is engaged, it forces both wheels on the axle to rotate at the same speed, regardless of traction. This ensures that power is delivered to both wheels, even if one is in the air or on a very slippery surface. This can significantly improve a vehicle's ability to traverse difficult terrain or maintain traction in adverse weather.

Differential locks can be found in various types of vehicles, most commonly in four-wheel-drive vehicles used for off-roading or heavy-duty applications. They can be manually engaged by the driver, or some systems are automatic. There are different types of differentials that can be locked, including the center differential, which can lock the front and rear axles together, and axle differentials, which lock the wheels on a single axle. Engaging a differential lock should typically only be done when maximum traction is needed, as it can make steering more difficult and potentially damage the drivetrain if used on high-grip surfaces like dry pavement.
