What is a tractor differential?
The tractor differential is responsible for changing the direction of power transmission, and in other words, this part consists of several bevel gears that take the engine power from the gearbox and distribute it to the wheels to rotate each part of the wheel. If the tractor does not have a differential, the wheels will lock and one wheel will drag on the ground when turning. In the process of power transmission, the power produced in the engine is transferred to the gearbox to create the necessary speed and torque, and its output will be transferred to the wheels using the crankshaft.
Differential Tasks in Tractor
In the tractor, the engine is placed on the chassis longitudinally, but the axis of the wheels must rotate transversely, so that the change of direction between the axis of the wheels and the axis of the engine will be possible with a differential.
2. Increasing the torque of the tractor wheels
Given that the differential has two bevel gears with different diameters, it increases the torque of the wheels and reduces their speed relative to the output axis of the gear.
3. Creating coordination between the wheels when turning the tractor
Differential Types
Locking differential will keep the speed of the shafts of one axis constant, so that the left and right wheels travel the same revolution. Also, this type of differential makes the axle with tension and without tension receive the same rotation. The automatic locking differential has a reasonable price and does not require the driver's intervention, but it makes a lot of noise when it is locked and unlocked.
2. Open differential
Open differential is the cheapest type of differential that is widely used in all vehicles. This differential model works in such a way that it will divide the output torque from the engine into two different directions, each of these outputs will have the ability to rotate at different speeds. One of the main disadvantages of this differential model is the inability to control the output torque. 3. Torque dividing differential
Torque dividing differential is one of the newest and most advanced types of differentials used in the vehicle manufacturing industry. In addition to its main duties, this differential model will also help with handling and maneuverability. This differential model uses speed sensors and accelerometers to constantly check the stability of the tractor and adopt the best strategy for dividing the power between the four wheels in this regard. These types of differentials are heavy and expensive, and they calculate the safety of the driver first, and speed is the second priority for them.
