Designed to make a
difference
The philosophy and key to the success of ZF SACHS Race Engineering has been the constant search for improvement and the willingness to push the boundaries of what is possible. The precise engineering and quality has resulted in SACHS Performance clutches and suspensions becoming an integral part of the world's most successful race cars.
Clutch Disc
SACHS Racing
Sintered metal, torsion-damped
Sinter-Pad clutch discs are subjected to very high loads and are complex components with a compact design. In addition to torque transmission, they fulfil additional tasks such as torsional vibration damping and extremely high heat resistance. Clutch discs with torsion springs also act as vibration dampers between the engine and transmission.
Advantages:
Higher transmittable torque compared to organic friction material.
Higher thermal capacity compared to organic friction material.
Higher burst number of revolutions
Lightweight and therefore lower mass and inertia
The torque damper of the clutch disc has a higher stop position - Maximum capacity of the torsion damper unit before stop position of locating rivets.
Very dirt resistant
Aggressive start performance
Effortless 1:1 exchange with OE clutch disc
The Technology
Clutch disc - sintered metal
The SACHS Racing SinterPad clutch disc 881861.999738 has a higher thermal load capacity and higher rpm resistance than organic standard clutch discs and is particularly resistant to dirt and oil. It enables harder starting, i.e. abrupt clutch engagement and significantly higher torques can be transmitted. Combined with the SACHS Performance clutch pressure plate, the result is an ideal clutch for motorsport use and for extremely performance-enhanced vehicles. - Benefit from the highest quality coupled with in-depth motorsport expertise.
Torsion damper
SACHS Racing sprung clutch discs are equipped with stronger torsion dampers in order to be able to transmit a higher maximum engine torque. The torsion-sprung SACHS Racing clutch disc 881861.999738 from ZF dampens engine vibration and protects your vehicle's transmission thanks to its reinforced damper design. SACHS torsional dampers are customised to the specific characteristics of each engine and vehicle combination. This damping system consists of a friction device and a set of springs for driving and idling operation. The coil springs allow limited torsion between the crankshaft and the transmission input shaft. Torsional dampers of the SACHS Racing clutch disc have a higher stop torque and offer maximum load capacity of the torsional dampers before block stop.
Clutch Cushion Spring
The cushion spring improves starting comfort and ensures that the clutch friction material are evenly supported. Cushion springs are corrugated spring plate segments with a spring travel of up to approx. 1 mm, which are riveted to the clutch disc carrier plate on the transmission side. In the case of high-performance SACHS Racing clutch discs, this cushion spring is generally omitted in favour of a higher transmittable torque compared to the standard clutch disc.
Quality "Made in Germany"
The clutch systems from ZF Race Engineering have brought motor sports teams worldwide to the forefront, from mass sports to Formula 1.
The knowledge gained from these race series has been flowing into the development of High Performance products for years.
