What is the Number of Axles on a Vehicle?
1 Answers
The number of axles refers to how many tire-mounted axles are underneath the vehicle. For example, heavy-duty trucks may have single rear axles, dual rear axles, or triple rear axles. The axle count primarily applies to cargo trucks, military vehicles, special-purpose vehicles, or large buses. The vehicle axle (also known as the wheel axle) is connected to the frame (or unibody) via suspension, with wheels mounted at both ends. Below are specific details: 1. Single Axle: Common household cars generally use a single axle. 2. Dual Axle: Road transport vehicles with a total mass under 19t and off-road vehicles (such as mining dump trucks) not restricted by road or bridge axle load limits typically adopt a simpler, cost-effective two-axle configuration. 3. Triple Rear Axle: Road transport vehicles with a total mass between 19-26t use a three-axle setup, while heavier vehicles employ four or more axles.
