How to Determine the Number of Axles on a Truck?
2 Answers
Count the number of axles with wheels underneath the truck from front to back; the number of rows of wheels corresponds to the number of axles. Below is relevant information about axles: 1. Introduction: Axles are primarily used in cargo trucks, military vehicles, special-purpose vehicles, or 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 more axles for semi-trailers, such as two-axle trailers with three-axle configurations or three-axle trailers with three-axle configurations. Ordinary family cars typically use a single axle. Road transport vehicles with a total mass less than 19t and vehicles not restricted by road or bridge axle load limits, such as mining dump trucks, usually adopt a simple and cost-effective two-axle design. Road transport vehicles with a total mass between 19-26t use a three-axle configuration. 2. Function: The axle's role is to bear the vehicle's load and maintain normal operation on the road.
Counting the number of axles on a truck is actually quite simple. After years of long-distance driving, my firsthand experience is to squat under the vehicle and count the number of wheels. Each pair of tires corresponds to one axle—for example, two pairs mean a dual-axle truck, and three pairs mean a tri-axle truck. Don’t forget that some trucks have steering axles or drive axles, which can make things a bit more complicated, but the general rule holds. The number of axles determines the load capacity and toll fees—dual-axle trucks usually carry up to five tons, while tri-axle trucks can handle up to ten tons. Overloading will definitely get you in trouble if the police check. I recommend doing this in a parking lot after stopping, never on the road—safety first. I’ve noticed many people overlook wheel size; larger rims might indicate a single axle with dual tires, a small detail you’ll recognize with practice.
