3tengelyes

3tengelyes is a Hungarian term meaning three-axled or three-axis, used to describe systems that have three independent axes of motion or support. The phrase can refer to both mechanical configurations with three axles in vehicles and to machinery or robotic assemblies that offer three degrees of freedom along or around three perpendicular axes.

In automotive contexts, 3tengelyes describes vehicles or trailers built with three axles. Such configurations increase payload capacity and improve weight distribution and stability, but they also impose stricter requirements for steering geometry, braking, and axle load limits according to national and European regulations. Three-axle setups vary, with some arrangements featuring three rigid axles and others comprising a tractor with a trailer, including differences in whether axles are driven or steered.

In machinery and robotics, 3tengelyes denotes systems with three independent axes. Common examples include three linear axes (X, Y, Z) used in CNC machines to position a cutting tool, or three rotational axes in gimbals and manipulators for orientation control. A three-axis CNC mill, for instance, moves a tool along three perpendicular directions to produce three-dimensional shapes.

Design considerations for 3tengelyes systems include load distribution, structural stiffness, precise axis alignment, and the sophistication of control systems and maintenance needs. The term highlights the level of freedom and complexity that comes with managing motion or support across three axes. It is used across automotive, manufacturing, and robotics domains to describe foundational three-axis capabilities.
