However, most require that both wheels still have some traction on the ground to operate and even when new will cause a wheel in the air to spin uncontrollably so as to be completely ineffective where off road traction is required. The traditional differential also allows for all power to be transmitted to the "path of least resistance" which is fine on highways because both wheels have some degree of traction but off road you often require substantial power and in this case even a small difference in traction can result in wheel spin and the subsequent loss of traction.Ī limited slip (LSD) differential is simply a standard differential (also called open) with either a fixed bias or dynamic biasing mechanism which serves to only "partially" lock up" the two axles by way of clutch plates or special gear design. The traditional differential design allows for an infinitely variable rate of differentiation ranging from 50:50 where both wheels turn at the same speed (straight line driving) and a ratio of 100:0 where one wheel spins freely and the other is not driven at all (not what you want to face when off roading). allow the wheels to travel at different speeds to allow cornering without drive train damage or tire damage. How the Aussie Locker is different from a standard differentialĪ standard differential is designed to perform two main traction related operations Transmit engine power via the drive line to the wheels, Allow "differential action", i.e. The combination of these two sets of opposing forces and the unique Aussie Locker design allow the automatic locking and unlocking of the driving gears when a vehicle turns or requires differential action.
The Aussie Locker relies on a simple and highly innovative mechanical design which makes use of two distinct sets of forces, "ground driven" forces acting on a wheel when cornering (forces the outside of the wheel to turn faster) and the engine driven forces through the drivetrain. It does not require any switches, external compressors, electrical cables, air lines, or pneumatic controls.
The Aussie Locker is a fully automatic and precision manufactured automatic differential locking device that does not require any manual operation to activate.
