What are the parts of a typical clutch pack assembly?
The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the driven plate, and the release bearing.
What is the main function of clutch assembly or how its works?
Most automotive clutches are a dry single plate clutch with two friction surfaces. No matter the application, the function and purpose of a clutch is to transmit torque from a rotating driving motor to a transmission. Clutches require a mode of actuation in order to break the transmission of torque.
What do the springs do on a clutch plate?
The springs mounted on the inner hub of the clutch plate cushion the clutch engagement. They work as a torsional vibration damper to absorb fluctuations in the engine’s power delivery. As the springs work as dampers the power delivery is smoother and more linear than if there were no springs.
When do you set the clutch drive strap?
The idea is to set the straps so that when they are in their ‘as assembled’ position, they are not under tension, nor are well clear of the pressure plate horns. They should be JUST touching. Under tension the clutch will slip due to decreased clamping pressure.
What are the driven members of a clutch?
The driven members consists of a disc or plate called clutch plate. The clutch is free to slide on the splines of the clutch shaft. It carries friction materials on both of its surfaces. When the clutch plate is gripped between the flywheel and the pressure plate, it rotates the clutch shaft through splines.
How does the pressure plate work on a clutch?
The cover plate is bolted to the flywheel, and the pressure plate exerts pressure on the driven plate through the diaphragm spring or through coil springs on earlier cars. The driven plate runs on a splined shaft between the pressure plate and flywheel.
What makes up the clutch pack on a motorcycle?
The clutch pack is made up of a stack of alternating steel plates and friction plates. The steel plates have tangs along their inner diameter that engage with the clutch’s inner hub, which is fixed to the end of the input shaft via splines.
The idea is to set the straps so that when they are in their ‘as assembled’ position, they are not under tension, nor are well clear of the pressure plate horns. They should be JUST touching. Under tension the clutch will slip due to decreased clamping pressure.
What is the purpose of the clutch plate?
The clutch pressure plate is an important part of your manual vehicle’s clutch system. It is a heavy metal plate that is controlled by springs and a lever. Its main purpose is to apply pressure to the primary clutch plate (or clutch disc), holding it against the engine flywheel.
Why do drive straps need to be aligned?
– If the drive straps are holding the flywheel up, or are under tension pressing on the pressure plate ‘horns’, more spacer-washers/shims are needed between the drive straps and flywheel – If there’s a gap between the drive straps and pressure plate horns, the spacing between the straps and flywheel needs reducing
Why are my Clutch straps not the right height?
If this is not done, clutch slip is inevitable. If using a pressure plate of unknown history, it is IMPERATIVE the clutch drive straps are set at the correct height. Many get this wrong and end up with a slipping clutch for some seemingly unfathomable reason.
