kopplingshål

A kopplingshål, commonly known as a "clutch hole" in English, refers to a small, circular hole found in the flywheel of an internal combustion engine, particularly in vehicles with manual transmissions. This feature is primarily associated with clutch systems used in cars and other machinery.

The kopplingshål serves as a mounting point for the clutch release bearing, also called the throw-out bearing. This bearing is responsible for applying pressure to the clutch diaphragm spring when the clutch pedal is depressed, disengaging the clutch and allowing the engine to run independently of the transmission. The hole ensures precise alignment and secure attachment of the bearing to the flywheel, facilitating smooth operation of the clutch mechanism.

In most manual transmission vehicles, the kopplingshål is located near the center of the flywheel, often adjacent to the input shaft of the transmission. During clutch installation or repair, mechanics must carefully position the release bearing into this hole to ensure proper function. Misalignment or improper installation can lead to clutch failure, transmission damage, or other driveline issues.

While the term is most frequently used in Swedish automotive contexts, similar components exist in other languages, such as the "clutch hole" in English or "trou de libération d'embrayage" in French. The design of the kopplingshål remains consistent across various vehicle manufacturers, though its exact placement and size may vary depending on engine specifications. Proper maintenance of this component is essential for the longevity and reliability of the clutch system.
