The axle is one of the most vital parts of the semi-trailer, which is directly related to the bearing, driving and braking of the vehicle. It is called the three core assembly of the trailer together with the engine and gearbox, and plays a decisive role in the stability and safety of the vehicle.
Maintenance free axle refers to the maintenance and maintenance cycle is relatively slow axle, typically oil lubrication instead of grease lubrication, gear oil injection in the hub unit, so that the hub and oil seal to form the storage space of gear oil, let the bearing immersed in gear oil, to ensure its full lubrication ability, in order to obtain a longer maintenance cycle.
The maintenance cycle is lengthy, the owners need to invest time, energy and thus on is reduced, the absence caused by the maintenance of the vehicle is also reduced, and the operation efficiency is naturally improved to a certain extent.
Semi Trailer Manufacturers remind us that maintenancefree axle only has longer maintenance cycle, which does not mean that maintenance is entirely unnecessary. Daily inspection and maintenance are still indispensable, especially for vehicles with elevated attendance rate, relatively bad operating conditions and lengthy distance transportation span of east, west, North and South. Even if the maintenance mileage is not reached, it is necessary to do a good job of routine inspection and maintenance of the axle, so as to completely ensure safety and give full play to the advantages of the use of the axle.
Notes for maintenance free axle use:
1. Check the axle fasteners before starting to see if there is any loosening phenomenon;
2. check whether the hubcap is damaged and 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 there is white or milk, it indicates that the lubricating oil is polluted;
4, every 12 months or 100,000 kilometers, to set up the wheel to check the rotation has no noise, bearing is sloshing;
5. every 12 months or 100,000 kilometers, it is necessary to open the oil injection hole, and use a magnet probe to extend into the lubricating oil to check whether there are impurities such as iron filings.
At present, the price of ordinary trailer axle on the market is influenced by brand, model, configuration and other factors. Take 13t drum brake as an example. Most brands are concentrated between 3000-4500 yuan, and high-end line products can float up to about 6000-8000 yuan. If it is a maintenance-free axle, commonly in the same specifications of the ordinary bridge price on the basis of an increase of 1000-1700 yuan. Of course, the number of users to buy also affects the final transaction price to a certain extent.
In fact, whether it is a maintenance-free axle or an ordinary bridge, we should remember the law of "three points to repair, seven points to maintain", do a good job of daily maintenance and inspection, in order to completely protect its function, prevent failure, extend the service cycle. In addition, it is also essential to choose brands with reliable quality. Dairong axle is specially tailored for trailers, focusing on axle/axle research and development and production for 20 years, quality and service can stand the test, special size trailer bridge can provide customized services, entering the market has consistently maintained zero quality disputes, won the trust of numerous customers.
