How Many Axles Does a Typical Passenger Car Have?

[OHarley]

Typically, a passenger car has two axles. Generally, the number of axles can be determined by counting the wheels on one side of the vehicle. The concept of axle count is mainly applied to cargo trucks, military vehicles, special-purpose vehicles, or some large buses. The axle is connected to the vehicle frame via the suspension system, with wheels mounted at both ends. Its function is to bear the vehicle's load and ensure normal operation on the road. Based on the number of axles, vehicles are categorized as single-axle, double-axle, front-four-rear-four, or front-four-rear-eight configurations. Highway transport vehicles with a total mass of less than 19 tons, as well as off-road vehicles like mining dump trucks whose axle loads are not restricted by road or bridge limitations, typically use a simple two-axle design. For highway transport vehicles with a total mass between 19 and 26 tons, a three-axle configuration is adopted. Vehicles with even greater total mass are better suited for four-axle or more configurations.
