Hõõrdkettaid
Hõõrdkettaid, often translated as friction discs or friction plates, are components used in various mechanical systems to transmit or control rotational motion through friction. They are typically found in clutches, brakes, and some types of variable speed drives. The principle of operation relies on the friction between two surfaces under pressure. When one disc is rotated and pressed against another stationary or rotating disc, the frictional force generated causes the second disc to move or to resist motion.
In a clutch system, friction discs are essential for engaging and disengaging the engine from the transmission.
In braking systems, friction discs (often called brake rotors when part of a disc brake assembly) work
