Racing Clutch SACHS RCS
Individual Configuration of Your Clutch
Number of Clutch Discs
The following clutch assemblies are offered:
- 1 disc
- 2 discs
- 3 discs
- 4 discs
The more clutch discs that are used, the more engine torque can be transferred by the clutch. More discs also allow a greater heat capacity of the clutch kit.
Racing Clutch SACHS RCS Diameter
Four clutch diameters (outer disc diameter) are available:
- 115 mm → RCS 115
- 140 mm → RCS 140
- 184 mm → RCS 184
- 200 mm → RCS 200
The greater the clutch diameter, the more torque can be transmitted by the clutch. The smaller the clutch diameter, the less mass and inertia. This means that low inertia allows the engine to accelerate quickly.
Larger clutches can accommodate much more heat and remain completely efficient, when smaller clutches may well be overheated.
SACHS Racing Clutch Friction Materials
Carbon
Very temperature resistant and very light. Often used under very severe conditions and provides the possibility of compact lightweight clutches (e.g. Formula 1).
Sinter
Due to its very light driven plates, often used in circuit/track racing, formula series vehicles, and touring vehicles.
Organic
A soft friction lining, gearbox protective but not very temperature resistant. Not used in extreme race conditions.
Sinter-Pad
Offers high wear range and is often used in applications where there are numerous starts.
Wear Range and Clamp Load
Racing Clutch Clamp Load
An engaged clutch creates the clamp load by using a diaphragm spring. The stronger the spring, the more engine torque can be transmitted by the clutch. To operate the clutch the release load must be applied by the driver. The higher the release load, the more difficult it is to operate the clutch.
Racing Clutch Wear Range
The wear range covers the wear of the clutch discs. Each racing clutch is designed for a certain wear range within which the engine torque is transmitted safely. Should the clutch plates be used beyond the prescribed wear range, the torque capacity will decrease and the clutch will begin to slip.
