The spelling of "drag link" follows the traditional English spelling system, using the letters d-r-a-g and l-i-n-k. In IPA phonetic transcription, this word is pronounced as /dræɡ lɪŋk/. The "a" sound in "drag" is pronounced like "cat" and the "i" sound in "link" is pronounced like "sit". The stress is placed on the first syllable, making it a two-syllable word. A drag link is a component used in automotive and other mechanical systems to transmit force and motion.
A drag link refers to a crucial component of an automobile's steering system. It serves as a connecting rod that links the pitman arm to the steering arm or the steering gearbox to the steering knuckle. This rigid link helps transmit the movement of the steering wheel to the vehicle's wheels, enabling controlled steering.
Typically, the drag link is a metal rod with threaded ends. One end is connected to the pitman arm, which is attached to the steering gearbox's output shaft. The other end is connected to the steering arm or the steering knuckle, depending on the type of steering system utilized.
As the driver turns the steering wheel, the rotational motion is transmitted through the steering gearbox to the pitman arm. The pitman arm then transfers this motion to the drag link, which ultimately causes the wheels to rotate appropriately, executing the desired steering input.
In vehicles equipped with a traditional "recirculating ball" steering gearbox, the drag link connects the pitman arm to the steering arm. Meanwhile, in vehicles with rack-and-pinion steering systems, the drag link connects the steering gearbox to the steering knuckle on each front wheel.
Due to its pivotal role in steering control, the drag link needs to be in optimal condition. Any excessive wear, damage, or misalignment could lead to imprecise steering, excessive play, or, ultimately, a loss of control over the vehicle's direction. Periodic maintenance and inspection of the drag link are essential for both driver safety and proper overall vehicle performance.
The word "drag link" is derived from the Middle English term "draggen" which means "to draw or pull". The term "drag link" itself refers to a mechanical component used in steering systems, particularly in vehicles. The link connects the steering gearbox or the pitman arm to the steering knuckle, allowing the wheels to turn in response to steering input. The name "drag link" implies that the component helps to "drag" or pull the wheels in the desired direction when steering.
