The tractor hub is a key mechanical element that plays an important role in the functioning of the vehicle. The hub is the central part of the wheel that connects the rim to the axle, allowing it to rotate. In tractors, the hub is particularly important due to the high loads and forces that occur when working in the field.

Construction of the tractor hub:

• Hub body: This is the main part, usually made of a durable metal such as steel or cast iron.
• Bearings: Inside the hub there are bearings that allow the wheel to rotate smoothly and efficiently around its axle.
• Seals: Seals protect the bearings from contaminants such as mud, dust and water.
• Mounting Bolts: The hub is attached to the axle by bolts that must be properly tightened to ensure the safety and stability of the wheel.

Functions and Importance:

• Load transfer: The hub must withstand high dynamic loads that arise when the tractor drives on uneven terrain.
• Ensuring stability: A well-designed hub ensures wheel stability, which is crucial for the safe operation of the tractor.
• Serviceability: Tractors need the ability to easily replace or service the hub and its components, minimizing machine downtime.

Problems and Maintenance:

Over time, the hub may wear out, which may result in looseness, noise or difficulty in turning the wheel. Regular maintenance, such as lubricating bearings and checking the condition of seals, is essential to ensure long hub life and trouble-free operation of the tractor.
