hajtási

Hajtási is a Hungarian term used as an adjective and, in some contexts, as a noun, relating to propulsion or drive. It derives from the noun hajtás, which denotes the act of driving, propulsion, or the mechanism by which power is transmitted to a driven element. The word is common in technical and engineering language.

In automotive engineering, hajtási refers to the propulsion or drivetrain of a vehicle. The hajtási rendszer includes the components that transfer power from the engine or motor to the wheels. In conventional internal combustion vehicles this encompasses the engine, transmission, driveshaft, differential, and wheel hubs; in electric vehicles it covers the electric motor, inverter, and associated power electronics and transmission elements where applicable.

The term also appears in other mechanical contexts. In bicycles and light machinery, hajtási describes the portion of the system that converts input energy into motion, such as the pedal drive and chain in bicycles or belt and gear drives in machinery. It can be used to discuss different configurations of power transfer and how they affect performance, efficiency, or handling.

Common compound terms include hajtási mód (drive mode), referring to selectable operating modes in a vehicle, and hajtási rendszer (drivetrain or propulsion system), describing the overall power transmission chain from source to driven output.

Grammatically, hajtási is the adjectival form derived from hajtás and is used to modify nouns related to propulsion, drive, or power transmission. It does not denote a standalone system but rather a category of systems and components within a broader mechanical context.
