Mittaxel

Mittaxel is a Swedish term that translates to "middle axle" or "mid-axle." It primarily refers to a type of axle found in multi-axle vehicles, specifically those with three or more axles. In a three-axle configuration, the middle axle is positioned between the front steering axle and the rear drive axle. This arrangement is common in heavy-duty trucks, buses, and other commercial vehicles.

The inclusion of a middle axle, often referred to as a pusher axle or tag axle depending on its placement and function, serves several purposes. It helps distribute the vehicle's weight more evenly across the chassis, which is crucial for compliance with road weight limits and for reducing stress on the tires and suspension. This distribution is particularly important when carrying heavy loads.

In some configurations, the middle axle may be steerable, which can improve the vehicle's maneuverability, especially in tight spaces or when making turns. In other cases, it is a fixed, non-steerable axle. The specific design and placement of the middle axle are determined by the vehicle's intended use, load capacity, and regulatory requirements. Vehicles with a middle axle generally offer increased stability and braking performance compared to those with fewer axles.
