Locking In: An Overview of Different Types of Diff Lockers

Locking differentials, which are also referred to as lockers or diff locks, force the wheels to rotate at the same speed no matter how much traction is present. When dealing with rough terrain or inclement weather, this is beneficial. As many as three differentials can be there in a 44 vehicle —at the front, rear, and centre in contrast to the majority of cars, which only have one.

Off-roading is one of the most well-liked adventure sports in the Tasmanian desert. Nearby bustling urban areas are only a few kilometers away from where most people drive to the desert dunes. However, ensure your car and its diff lockers are in good condition before heading out to Tasmania's off-roading trails.

What Does a Diff Lock Do? An Overview

Two wheels are supported on each axle of a car. The wheels of a moving vehicle rotate at a similar rate. However, a car's wheels often rotate at varying speeds when it turns a corner. This is because during a turn, the inside wheels move a shorter distance than the outside wheels, resulting in this situation.

A differential is fixed between the two wheels to allow the car to make a sharp turn without being damaged. This works best when driving on tar because it allows the wheels to turn at varying speeds. Differentials direct power to the wheel that is most straightforward to turn. On the other hand, a diff lock locks the axle and permits equal motion from both wheels.

Due to power being transferred to the wheel that has the least traction while off-roading, the differential can be problematic. Diff lockers come into play at this point and anchor the differential. The two wheels can turn at the same speed regardless of traction thanks to a diff lock, which locks the axle.

What are the Various Types of Locking Differentials?

1. Automated Diff Locker

Automatic Diff lockers automatically lock when traction is lost. Once traction is once again detected, it will unlock once more. Interestingly, some automated locks function by locking the differential permanently and only freeing it when one wheel needs to spin faster than the axel. These locks prevent a wheel from spinning more slowly than the axel and driving system.

Diff Lockers 

If any wheel loses traction, automatic diff locks automatically engage. When traction is regained, this lock, however, automatically disengages. Additionally, some automatic diff locks only release when one wheel must spin more than the others.

2. Manual Diff Locker

The use of manual diff lockers gives the driver of the car control over when the differential is locked and when it is unlocked. When the differential is unlocked, it offers the same driving capabilities as a typical open differential. However, a driver can have the option of deciding when extra traction is needed. From the driver's seat, a switch or lever can be used to lock the differential.

Examples of manual lockers include:

• The ABR AirLocker makes use of compressed air.
• The Ox-Locker that locks the differential with a cable-operated mechanical system
• The Eaton ELocker makes use of an electromagnet.

The driver is the only one who can operate manual diff locks. A manual diff lock is activated by the driver simply depressing the diff lock switch. Press the diff lockers button once more to deactivate the car's diff lock once you have left the challenging terrain. The diff lock might be required a few times on rough terrain.

Conclusion

Even when you turn the steering wheel, the vehicle tends to travel straight when the differentials are locked, and all wheels are spinning at the same rate. Particularly when the front differential is locked, this happens. Therefore, you should take care.

Avoid driving on surfaces that prevent a little wheel slip when the differentials are locked. The tyres will grip surfaces like paved or hard rock roads. The wheels will all want to spin in different directions as you turn. This will not be possible, though, if differentials are locked. Your car's driveline will be put under tremendous stress as you go on cornering, and this stress will eventually lead to failure. Wind-up is the term for this. In order to avoid hitting the blacktop, unlock your diff lockers and exit 4WD.
