Micro truck rear axle models are generally 121, 130, 140. Light truck and dump truck rear axle models include 145, 1058, 1069, 1070, 1080, 1081, 1090, 153, 457. The last two are specifically for heavy trucks, and among these models, there are extended, shortened, and standard versions. Definitions of various trucks: Micro truck: A micro truck is a type of truck. According to China's motor vehicle specifications, "micro" is defined as: vehicle length ≤ 3.5m, total mass ≤ 1800kg. Light truck: Light trucks refer to N1 category vehicles in the N-class truck classification with a maximum design total mass not exceeding 3.5 tons. Dump truck: A dump truck is a vehicle that unloads cargo by hydraulic or mechanical lifting, also known as a tipper. It consists of components such as the vehicle chassis, hydraulic lifting mechanism, cargo compartment, and power take-off device. Heavy truck: Heavy truck is the abbreviation for heavy-duty truck. This is a colloquial, traditional, and informal term for heavy-duty trucks and semi-trailer tractors, including various specialized vehicles seen on highways (water trucks, fire trucks, road sweepers, tankers, mixers, etc.), dump trucks (earth-moving trucks, all equipped with lifters), trucks (for transporting goods, including livestock), and some less common off-road vehicles (mostly military).
I've noticed while driving that there are quite a variety of rear axle types. Mainly there's the drive rear axle, which transmits power to drive the rear wheels, commonly used in rear-wheel-drive vehicles; then there's the non-drive rear axle, primarily for wheel support without power transmission, like the rear structure of front-wheel-drive cars; and also the independent suspension rear axle, now widely used in many sedans and SUVs to improve comfort and handling. Specific models depend on manufacturers - classifications differ between GM and Ford for example. When choosing, consider vehicle purpose and driving habits rather than just focusing on specifications.
As an automotive enthusiast, there are quite a few rear axle models to know about. They're mainly divided into driven and non-driven types. Driven rear axles often feature differential designs, with models like the Dana Spicer series or versions with differential locks being suitable for off-road vehicles; independent rear axles are more commonly found in high-end models. Understanding these can help you assess performance when buying used cars. I recommend checking out automotive forums for real-world feedback.
I've encountered many types of rear axles while repairing vehicles. The structural differences in drive axles are significant, with semi-floating and full-floating bearing designs being common. Semi-floating axles are lightweight and used in sedans, while full-floating axles are more pressure-resistant and suitable for trucks. Non-drive axles simply support the wheels. The actual model should be selected based on vehicle weight and road conditions to avoid rapid wear.
