4 Important Points to Understand on How Auto Clutch Really Works

A vehicle that has a manual transmission has a clutch that makes an interruption to the power transfer between the drivetrain and engine. Such interruption, together with gradual power application while the clutch is engaged, will enable the vehicle to be started in a smooth way from a stop. This will prevent gears from grinding during shifting. The clutch mechanism is composed of different parts which work together to carry out this function. To understand exactly how clutch works, please read on.

Flywheel

This component is a huge metal disc connected to the engine’s crankshaft. The engine’s action can turn the flywheel on which is a contact point through which the transfer of power from the running engine to the drivetrain and transmission takes place. The flywheel comes with teeth in its circumference involved by the starter motor so that the engine will be turned over. This part is also made with smooth outer surface which the clutch disc grips as the clutch is involved.

Pressure Plate and Clutch Disc

A vehicle’s clutch disc is a round metal covered with coating. As the clutch is engaged, this disc is pressed against the flywheel. Meanwhile, the pressure plate makes use of a system of levers and springs for clamping the disc against the flywheel as the clutch is involved as well as release the disc while depressing the clutch pedal. The clutch disc’s hub is connected to the transmission’s input shaft and squeezing together the flywheel, pressure plate and disc will result in the transfer of power from the engine which will cause rotation of the transmission shaft.

Clutch Connection

The vehicle’s clutch pedal is linked to the mechanism of the clutch through a mechanical or hydraulic system. A mechanical linkage has cables or rods that link the clutch pedal to the vehicle’s pedal. On the other hand, a hydraulic linkage utilizes lines composed of hydraulic fluid. The linkage’s function is to move the sliding bearing which moves away the pressure plate from the clutch disc while the depressing the pedal.

Automatic Transmissions

A more complicated mechanism is used in automatic transmissions with the presence of electronic controls and sensors while engaging or disengaging the clutch. Some friction discs and steel plates or transmission band series, which tighten and released surrounding the clutch housing, will be activated by hydraulic pressure. As either of such systems is involved, there will be power transfer from the vehicle’s engine to its transmission, and then the vehicle moves.
