An locking differential plays an important role in the vehicle operation . In this article we explain the different types of locking differentials, what are the advantages and disadvantages of it, what the price it has and much more. Continue reading the article!
What is the self-blocking differential?
The Locking differential is responsible for transmitting the engine force to the wheels together with the transmission system. While most differentials make tyres rotate at different speeds, the locking differential locks the axle so that both tyres on that axle rotate at the same speed.
The locking differential can be located on the front and rear axles. The system widely used in sports vehicles and off-road vehicles to provide greater traction to the vehicle, leading to better lap times in sports competitions.
What is the main function of a locking differential?
The locking differential allows the engine force to be transmitted to one of the vehicle’s wheels when the opposite side of the same axle loses grip.
What are the different types of Locking differential systems ?
-
Mechanical locking differential
The mechanical locking differential has inside a spring-activated mechanism that limits the rotation of one of the wheels when it finds that one of them is without grip.
-
Mechanical locking differential with special gears
This type of automotive differential is characterized by having a Torsen system and is activated by wheels touch with the ground.
-
Mechanical locking differentials with Ferguson-type visco coupler
This type of differential is only used in four-wheel drive vehicles and can work simultaneously with the rear axle and the front axle.
-
Electronic locking differentials
An electronical locking differential uses sensors from the ABS and EPS braking system. This causes traction not to be lost, preventing a wheel´ grip loss. The electronic differential is more versatile and is present in most new cars.
What are the advantages of a Locking differential?
Most car drivers prefer a vehicle with a locking differential, as they are durable and do not require much maintenance. In addition, they are known to provide good traction to the vehicle in any situation.
According to experts, this type of differential forces the vehicle to make corners correctly and helps the driver in all maneuvers.
What are the disadvantages of a locking differential?
Uneven wear on vehicle tires
On the outside part, the difference in wear on the tires is clearly visible. This is due to the operation of the locking differential and is even more visible at the end of the tire life cycle. It is important to proceed with the steering alignment in order to be able to get around this situation.
Circulation in snow or ice conditions
The locking differential does not provide the same level of safety when driving with snow or ice, because both wheels lose traction. An ineffective operation of this component can lead to damage inside.
What is the importance of locking differencial in racing vehicles?
A high-performance locking differential makes the vehicle perform above average in corners and this is where vehicle traction is put to the test. Racing vehicles only use this type of differential on the front axle, as if used on the rear axle, driving would be much more demanding for the driver and would not bring any advantages.
What is the price of a locking differential?
The price of a differential depends on the model and the brand in question, and can fluctuate between 200 and 2500€
KROFtools reminds you that you must use a flange removal kit or a bushing extractor to replace or repair the locking differential.
