Kardánhoz

Kardánhoz is a Hungarian grammatical form, the to- or toward-type case ending of the noun kardán. It functions within sentences to indicate a direction, attachment or relation toward a Cardan joint (universal joint) in technical language. The word itself is not a separate concept, but a case-inflected form used in contexts involving the Cardan joint or components connected to it.

Kardán (kardáncsukló or kardántengely) is a mechanical element that transmits rotary motion between shafts that are not collinear, allowing angular misalignment while transferring torque. The classic Cardan joint consists of two yokes connected by a cross-shaped central element and bearings that accommodate relative movement between the shafts. It is widely used in drive shafts of vehicles, machinery and robotics to accommodate suspension movement, steering geometry, or misalignment.

In Hungarian technical usage, kardánhoz appears in phrases describing attachment, mounting, or relation to the Cardan joint. For example, säga tengelyt csatlakoztatják a kardánhoz (the shaft is connected to the Cardan) or a kardánhoz viszonyított szög (the angle relative to the Cardan). The form helps specify locations, orientations, or connections specific to the Cardan assembly, without implying a standalone device beyond the joint itself.

Etymology and naming: the term kardán originates from Cardano, as in Cardan joint, reflecting the historical association of the universal joint with Cardano’s name. In Hungarian, the core concept remains the Cardan joint, with kardánhoz serving as a grammatical, contextual reference to that component.
