Does maintenance-free trailer axle work?

The axle is one of the very important parts on the semi-trailer, which is directly related to the bearing, driving and braking of the vehicle, and the engine and transmission are called the three core assembly of the trailer, which plays a decisive role in the stability and safety of the vehicle.

Maintenance-free trailer axle refers to the maintenance and maintenance cycle is relatively long axle, general oil lubrication instead of grease lubrication, in the hub unit with gear oil, so that the hub and oil seal form gear oil storage space, let the bearing soaked in gear oil, to ensure its full lubrication capacity, in order to obtain a longer maintenance cycle.

The longer the maintenance cycle, the owners need to invest less time, energy, etc., and the absence due to vehicle maintenance is also reduced, and the operation efficiency is naturally improved to a certain extent.

It should be noted that maintenance-free trailer axle is just a longer maintenance cycle, does not mean that there is no need to do maintenance, daily inspection and maintenance is essential, especially high attendance, the use of relatively bad working conditions, east-west north and south large span long-distance transport vehicles, even if not reach the maintenance mileage also need to do routine inspection and maintenance of the axle, Only in this way can the safety be fully guaranteed and the advantages of the axle be fully brought into play.

Maintenance-free trailer axle use precautions:

1. Check the axle fasteners before starting the train to see if there is loosening;

2, check whether the hub cap is damaged, whether there is oil leakage;

3. Regularly observe whether the gear oil in the hub is above the normal level and whether it is polluted. In general, the lubricating oil is dark, if it appears white or milky, it indicates that the lubricating oil is polluted;

4, every 12 months or 100,000 kilometers, the wheel should be set up to check the rotation has no abnormal sound, bearing shaking;

5. Every 12 months or 100,000 kilometers, it is necessary to open the oil filling hole and use the magnet probe to reach into the lubricating oil to check whether there are impurities such as iron filings.

At present, the average trailer axle on the market, the price is affected by brand, model, configuration and other factors, to 13t drum brake as an example, most brands concentrated between 3000-4500 yuan, high-end line products can float to about 6000-8000 yuan. If it is a maintenance-free trailer axle, generally in the same specification of the ordinary axle price increase on the basis of 1000-1700 yuan. Of course, the number of users to purchase quantity also affects the final transaction price to some extent.

In fact, whether it is maintenance-free axles or ordinary axles, we should keep in mind the rule of "three points of repair and seven points of maintenance", do a good job of the daily maintenance and inspection, in order to fully protect its function, prevent failure and extend the service cycle.
