What is the term for the total weight supported by a given axle assembly?

The term that refers to the total weight supported by a given axle assembly is known as Gross Axle Weight (GAW). This measurement represents the weight that is borne specifically by one axle, taking into account everything that the axle is carrying, including the weight of the vehicle itself along with any load it is supporting.

Understanding the Gross Axle Weight is crucial in various contexts, such as ensuring compliance with weight regulations, optimizing vehicle performance, and managing tire wear. By monitoring the GAW, drivers and fleet managers can ensure that loads are evenly distributed, which helps improve the safety and efficiency of vehicle operation.

The other terms mentioned, such as Gross Vehicle Weight (GVW) and Net Axle Weight (NAW), signify different concepts; GVW refers to the total weight of the vehicle including all its load, while NAW typically refers to the weight of the axle excluding any additional load. Curb Axle Weight (CAW) focuses on the weight supported by an axle while the vehicle is at rest, but again does not define the overall load the axle supports when fully loaded.
