Kedjelänkning

Kedjelänkning is a Swedish term that translates to "chain steering" or "chain steering mechanism." It refers to a type of steering system used in some vehicles, particularly in older or specialized machinery. In a kedjelänkning system, a chain or series of chains is employed to transfer rotational motion from the steering wheel or control mechanism to the wheels that are being steered.

This system typically involves sprockets connected to the steering input and to the steering arms of the wheels. As the steering mechanism is operated, the chain moves, causing the sprockets to rotate and thus turn the wheels. Kedjelänkning can offer a robust and direct mechanical connection, making it reliable in demanding environments. However, it can also be prone to wear, require regular lubrication, and may exhibit some slack or play over time, which can affect steering precision.

While not common in modern passenger cars, which predominantly use rack and pinion or recirculating ball steering systems, kedjelänkning might still be found in certain agricultural equipment, industrial vehicles, or vintage automobiles where simplicity and durability were prioritized. The design allows for a potentially compact steering linkage in some applications. Maintenance of the chain tension and lubrication are key aspects of ensuring proper function and longevity of a kedjelänkning system.
