Low-profile axles

The low-profile axle is a typical semi-trailer support axle, which is often referred to as the rear axle, playing the role of load-bearing, braking and maintaining driving. Unlike ordinary semi-trailer axles, low-profile axles are a special type of axle, from the appearance to the performance, there are certain differences with ordinary axles

1、What does a lowbed axle look like?

From the appearance of the low-profile axle, and the ordinary drum brake bridge is relatively good to distinguish, its wheel end part size is smaller, such as the brake drum and hub, are smaller than the general semi-trailer axle. This also results in a smaller ground clearance height of the lowbed axle.

2, low flatbed axle features because the low flatbed axle height from the ground is short, to a certain extent, to reduce the vehicle's centre of gravity, the goods more convenient to get on and off the car, driving stability has also been correspondingly improved. When the vehicle transports ultra-high goods on the height-restricted road, the passability will also be stronger. Secondly, the wall thickness of the low-profile axle is higher and stronger. Compared with ordinary semi-trailer axles, the 20Mn2 seamless steel tube chosen for the lowbed axle has a higher wall thickness, which can be seen visually from the cross-section of the axle tube below: not only the axle beam, but also the wheel hub, brake drum, friction pads and other accessories of the lowbed axle are special, from strength to toughness to wear resistance, etc., are fully up to standard.

3, the application field of low flatbed axle low flatbed axle is mainly used in low flatbed semi-trailer. Low plate semi-trailer in the industry commonly known as "big plate car", this type of vehicle is specifically used for the transport of heavy vehicles, rail vehicles, mining machinery, forestry machinery, engineering machinery and other non-disassembled bulky goods, can also be used for the transport of sedan vehicles
