Functions Of Clutch Kits

Most motorists prefer manual transmission because it gives them more control over their car and allows them to save on gas. But then, a good clutch is needed to go with that. A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work. While typically the motions involved are rotary, linear clutches are also possible. A clutch is a subcomponent of a car’s manual transmission system that engages and disengages the engine to the gearbox and transfers torque to the vehicle’s transmission in split-seconds. Currently for Subaru cars the best clutch kits are Subaru BRZ clutch kit and Subaru WRX clutch kit.

A clutch kit comes with it a clutch disc or a clutch friction disc and clutch pressure plate, although some clutch kits have pilot bushings or pilot bearings. A clutch assembly consists of many small parts, but the major components are as follows.

The clutch flywheel: The clutch flywheel is connected directly to the engine crankshaft and, therefore, spins with the engine’s motions.

The clutch pressure plate: Bolted to the clutch flywheel is the second major component: the clutch pressure plate. The spring-loaded pressure plate has two jobs: to hold the clutch assembly together and to release tension that allows the assembly to rotate freely.

The clutch disc: Between the flywheel and the pressure plate is the clutch disc. The clutch disc has friction surfaces similar to a brake pad on both sides that make or break contact with the metal flywheel and pressure plate surfaces, allowing for smooth engagement and disengagement.

Clutch bearing and release system: These components work together simultaneously and are key to the engaging and disengaging process. They are the release, or throw-out bearing, and the release system itself. The clutch release bearing is connected to one end of the hydraulic (or clutch fork mechanism) and rides on the diaphragm spring of the clutch. Depending on the type of release system, the throw-out bearing either pulls or pushes on the pressure plate diaphragm spring to engage or disengage the pressure plate’s grip on the clutch disc. 

Running through the center of the pressure plate, clutch disc and flywheel is the input shaft of the transmission. The shaft takes the input, or power of the engine, and sends it down through the gears to the wheels. At the point where the input shaft enters the transmission is a beefy bearing that bears most of the shaft’s spinning load. In the middle of the flywheel is a much smaller pilot bearing. The pilot bearing centers the input shaft in the center of the flywheel so it can rotate while the clutch assembly is engaged and disengaged. The input shaft is what the clutch disc itself is connected to. Clutches used by trucks and racing cars, however, ceramic is used to reduce clutch disc friction. If a clutch has better materials used for friction and stronger springs to go with it, chances are you get faster and harder launches, quicker shifts, and much better durability.
