What Is A Lunchbox Locker And How Does It Work?

A lunchbox locker is uniquely designed to uniformly divide power between both wheels. This happens irrespective of which wheel possesses traction. However, it needs to stay open in normal driving situations to make sure the differential work effectively. The lunchbox lockers are also famously known as drop-in lockers.
The below section shows how a lunchbox locker works:
Inside a lunchbox locker, the hole in which the center pin passes through is not shaped like a perfect circle but it is shaped like an oval. Whenever torque is exerted, it forces the pin to shift slightly. Whenever the pin shifts, it pushes the cam gears inside the axle gears. Hence, they lock together.
When no torque is applied, the pin regains to the middle of the oval. After that, it stops pushing the cam gears towards the outside. As a result, the cam gears will spin over the axle gear and this will make the ratcheting noise. The lunchbox lockers are well-known for making this noise.
