Many riders who want to enter the transportation industry do not understand what the axles of a trailer mean? What's the difference? The following will unravel the mystery for you.
The tires on both sides of the trailer are connected by axles. The more axles, the greater the load capacity of the trailer. To put it simply, there are several rows of tires, a trailer is a trailer with several axles.
Different axis numbers have different applications
1. Ordinary family cars generally use single axles.
2. Road transport vehicles with a total vehicle mass of less than 19t and vehicles that do not run on highways whose axle load is not restricted by roads and bridges, such as mining dump trucks, all adopt a two-axle solution with simple structure and low manufacturing cost.
3. Road transport vehicles with a total mass of 19-26t adopt three-axle form, and cars with larger total mass should adopt four-axle or more than four-axle form.
Different number of axles load different
Two-axle freight cars are 17 tons; three-axle freight cars are 25 tons (27 tons of two-axle cars and one-axle trailers); four-axle freight cars are 35 tons; five-axle freight cars are 43 tons; and six-axle freight cars and above are 49 tons.
Daily maintenance and maintenance of axles
1. Before the vehicle runs, check whether the external connecting bolts of the axle are loose, whether the axle is leaking oil, whether the wheel hub and the reducer assembly are abnormal noise, etc.
2. Compulsory maintenance of axles: Compulsory maintenance should be carried out between 3000km and 5000km depending on the operating conditions; the first maintenance includes: changing the lubricating oil, gear oil, checking the toe of the front axle, adjusting the brake clearance, etc., and checking each Fasteners, etc.
3. Regular maintenance of axles: Regular maintenance is carried out every 10000km after the first maintenance; the contents of regular maintenance include: replace the lubricating oil, tighten the fasteners, check the toe, check the degree of wear of the brake friction lining, and reach the wear limit Replace and adjust the brake clearance in time, check the reducer assembly, whether the clearance between the driving and driven gear and the driven gear is too large, whether the gear oil exceeds the efficiency of use, if there are similar situations, adjust the clearance and replace in time grease.
