Maintenance-Free Axle
Maintenance-free axles appear more frequently on some high-end freight vehicles. The purpose of their application is to extend the maintenance cycle of the axle, reduce the frequency of maintenance, improve vehicle operation efficiency, and reduce downtime due to maintenance.
The so-called maintenance-free axle is to use oil lubrication instead of grease lubrication. Gear oil is added to the hub unit. The hub and oil seal form a storage space for gear oil. The bearings are soaked in gear oil to ensure their sufficient lubrication ability. Achieve longer maintenance intervals than ordinary axles.
Advantages of maintenance-free axles
1,The axle oil change interval is extended.
This is also the most obvious advantage of maintenance-free axles. Under normal circumstances, the maintenance cycle of ordinary axles is mostly concentrated between 20,000 and 50,000 kilometers. For maintenance-free axles, it can be extended to 5 years/800,000 kilometers. The car owner only needs to conduct a simple visual inspection at intervals of about 100,000 kilometers. That's it, it can help car owners save a lot of time and energy.
2,The bearing performance is more stable.
The bearings of maintenance-free axles are soaked in lubricating oil, which can achieve a more sufficient lubrication effect when rotating. The oil circulates inside the wheel hub, and the working condition of the bearings is more stable.
3.The service life of the axle is extended.
The bearing is soaked in lubricating oil. When it generates debris or impurities during operation, the lubricating oil will clean them up and deposit them inside the hub cavity during the circulation process, reducing the loss caused to the bearing and extending the service life of the axle.
4.Comprehensive vehicle maintenance costs are reduced.
According to relevant survey data, maintenance-free axles can help car owners save a lot of expenses during the service life of the wheel end. If axle maintenance is charged at 1500 yuan per time, nearly 10,000 yuan can be saved over 150,000 kilometers.
