What is the tonnage of a 1080 rear axle?
2 Answers
1080 is an 8-ton rear axle. The rear axle refers to the rear drive shaft component of the vehicle's power transmission system, which consists of two half-axles that enable differential movement. It also serves as a device to support the wheels and connect the rear wheels. The front and rear axles refer to the parts of the front and rear wheel axles. The front axle includes components such as shock absorber springs, steering gear, and balance shafts, while the rear axle also includes the drive shaft and transmission gears. The front axle of a vehicle is not a drive axle, whereas the rear axle is the drive axle, which not only bears the load but also functions in driving, deceleration, and differential action. For four-wheel-drive vehicles, a transfer case is additionally installed in front of the rear axle. Rear axles are categorized into solid axles and semi-axles, with solid axles paired with non-independent suspensions and leaf spring suspensions, and semi-axles paired with independent suspensions and MacPherson strut suspensions.
In the world of trucks, when people mention the 1080 rear axle, I often come across it, and it directly indicates a load capacity of 10.8 tons. The rear axle is located in the rear wheel section of the truck and is responsible for bearing the weight of the cargo. This number is derived from design standards—simply divide 1080 by 100 to get the tonnage. I’ve driven quite a few trucks myself, and this numbering system is very common in domestic trucks, such as the FAW or Dongfeng series. If you see this model, it means the truck can handle medium to heavy loads, but don’t overload it, as the axle can easily deform or even break. It’s recommended to regularly check the rear axle gear oil to avoid accelerated wear under long-term heavy loads. During routine maintenance, I always help the owner check this label to ensure the right cargo box is matched, as overloading not only leads to fines but is also dangerous. In short, 1080 means a 10.8-ton rear axle—always operate within limits and prioritize safety.
