Manual transmission clutch system is one of the components not necessarily seeing much innovation. Manufacturers sometimes do big and crazy things, but it is rare. Last time, it was a Porsche equipped with Carrera GT's carbon clutch, but recently there has been a movement of General Motors using a slave cylinder operating electrically, recently patent application was filed.
This application was excavated by Super Ellis car on Friday Bozzetatarević In Jalopnik this describes a "clutch-by-wire" system that essentially operates the clutch of the vehicle using servos and potentiometers (like throttle in modern engines). I will explain why it is an exciting idea.
The clutch is used to connect and disconnect the engine of the vehicle from the manual transmission so that the driver can change the gear. In the conventional clutch system, the clutch pedal is connected to the clutch in two ways. Older cars like the Porsche 911 (and many other cars) before 1987 used cables to connect the pedals to the clutch. Most other cars use a hydraulic system with a hydraulic pedal attached to the hydraulic master cylinder. This pedal uses fluid pressure to activate the transmission's own slave cylinder.
Both systems have drawbacks. Cable clutches require frequent driver effort to operate frequently and are frequently adjusted as the cable expands over time during use. Although hydraulic clutch never needs to be adjusted, it is known that leakage occurs over time because the element and brake fluid deteriorate the rubber seal of the system. This electronic clutch solves all these problems.
