How does a lunchbox locker work?

Published in Automotive Differentials 1 min read

A lunchbox locker, used in differentials, functions as a ratcheting device that locks up upon torque application, enhancing traction. When cornering, it allows for differential action.

Here's a more detailed breakdown:

  • Default Ratcheting Position: The locker starts in a ratcheting position.
  • Torque Application: When torque is applied, it locks up.
  • Cornering: It unlocks, allowing differential action when entering a corner.
