Introducing the KAM Differentials electronic locking differential. ‘The Drop in Locker’
The KAM ‘Drop in Locker’ has the simplest operating system of any switchable diff lock,
•complicated wiring loom or air lines.
•2 wires and an illuminated dash mounted switch is all that is required.
•The uncomplicated switch arrangement also means the ‘Drop in Locker’ is the fastest switchable diff lock to install,
•no cutting or welding is required.
•A simple drilled and tapped hole for the electrical cable gland is the only machining operation that is required.
•A competent DIY mechanic should take no more than a few hours to completely install a KAM ‘Drop in Locker’ from start to finish.
•No special oils are required and service parts such as bolts and bearings are all the same as Land Rover original.
Vehicles both 2 and 4 wheel drive, require differentials. The differential allows the outer wheel to rotate faster than the inner wheel during a turn, this is necessary as during the turn the outer wheel travels further and faster than the inner wheel. The speed of the outer wheel is proportionally faster than the inner wheel. Without a differential the transmission would bind up during road driving causing tyre scrubbing and unpredictable steering. The differential assembly also couples the input shaft (usually a prop shaft) to a pinion which in turn drives a crown wheel which is attached to the differential. The crown wheel and pinion also provides the final drive gear ratio for the vehicle. From the differential half shafts connect the drive to the wheels. On high traction surfaces such as tarmac, torque is transferred equally through the differential to the wheels, driving the vehicle forward. On low traction surfaces like snow or when a wheel lifts clear of the ground while off road the drive follows the path of least resistance allowing the wheel with the least or even no traction to spin freely as the torque is directed through the differential.
This basic system is known as an open differential and is typically fitted to vehicles as standard. An open differential is ideal for a road going vehicle but has limited capability off road. Four wheel drive transmissions provide twice as much traction, but even the most capable 4x4 vehicle can lose grip or lift a wheel in extreme conditions causing the vehicle to spin to a halt.
Fitting a KAM electronic locking differential known as the ‘Drop in Locker’ due to its ease of installation can make all the difference between success and failure when tackling off road obstacles or negotiating very low grip conditions.
Operating a dash mounted switch sends an electronic current via 2 high grade carbon brushes to 4 high power solenoids inside the differential which when energised, simultaneously pull a locking ring into engagement with the differential sun gear, immediately locking the differential gears and preventing the drive from following the path of least resistance. The unique patented design provides instant traction by transferring drive equally to each wheel. With ‘Drop in Lockers’ fitted front and rear your 4x4 can be driven in a much slower, more controlled manner reducing the likelihood of damage to the vehicle and the environment.
A manually operated locking differential means that you the driver has control, enjoy the precise and predictable handling of an ‘open’ diff on road and then 100% drive ‘locked’ when you need it most off road, simply engage and disengage the ‘Drop in Lockers’ as and when you need them.
