How to Determine the Number of Axles on a Truck?
2 Answers
Count the number of axles with tires underneath the truck. For trucks, the number of axles is determined by counting the rows of wheels from front to back. Below is some related information about axles: Introduction: Axles are primarily used in cargo trucks, military vehicles, special-purpose vehicles, and a small number of large buses. The axle is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. Classification by the number of axles includes: single axle, double axle, front four rear four, front four rear eight, and for more axles, semi-trailers like two-axle to three-axle or three-axle to three-axle configurations. Ordinary family cars typically use a single axle. For road transport vehicles with a total mass of less than 19 tons and vehicles not restricted by road or bridge axle load limits, such as mining dump trucks, a simple and cost-effective two-axle design is adopted. Road transport vehicles with a total mass between 19-26 tons use a three-axle configuration. Function: The function of the axle is to bear the vehicle's load and maintain normal driving on the road.
When I drive long distances, I often need to pay attention to the number of axles on trucks. The simplest method is to stand at the side of the vehicle and count the pairs of wheels from the front to the rear—one pair of tires counts as one axle. For example, a two-axle vehicle has four wheels, and a three-axle vehicle has six. The number of axles is actually related to the vehicle's load capacity; the more axles a heavy-load truck has, the more stable it is while driving. I remember when I first started transporting goods, I was fined for overloading because I didn’t understand axle counts properly. So now I’ve developed a habit of checking the vehicle manual or registration certificate before driving, or paying attention to the small plate on the body, which indicates the number of axles. After all, safety comes first, especially on roads with many curves—vehicles with more axles have stronger braking performance, reducing the risk of skidding and accidents.
