Systems for Automatic Transmissions

LuK has gained a high profile position at an early stage as an engineering partner for manufacturers of vehicles with automatic transmission.LuK has been producing dampers for automatic transmissions since as early as 1983. In 1983, LuK enhanced its position by developing and producing its own torque converter in its subsidiary plant in Wooster, Ohio, USA. Due to the expected growth of the automatic transmission market in passenger cars in Europe and Asia too, LuK commenced converter production in its plant in Bühl, Germany, enhancing its focus on the customer. As well as high-performance converters and lock-up clutches, dampers for lock-up clutches and brake bands are also part of the LuK product range.

• Hydraulic torque converter 
• Multi Function Torque Converter (MFTC)
• Lock-up clutches
• Damper for lock-up clutches
• Super Slim Stator

ZF Sachs Performance

Race drivers all over the world, from club sport to Formula 1 Racing, again and again celebrate successes with products from ZF Sachs, relying on a technological competence originating more than 100 years ago.

It was August 1st in 1895 when Ernst Sachs and Karl Fichtel established the “Schweinfurter Präzisions-Kugellagerwerke Fichtel & Sachs” and started the production of ball bearings and bicycle hubs. But it was as early as the 1920’s that the company broadened it activities into the new automotive industry and soon became a specialist in this field.

Self-adjusting clutch

1 Self-Adjusting Clutch (SAC)

1.1 SAC increases driving comfort

As clutches are subjected to continuous wear and tear, LuK, as the first clutch manufacturer worldwide, has invested tremendous efforts in the development of a wear adjustment solution, which was successfully launched for volume production in 1995. SAC technology has since asserted itself in a wide variety of motor vehicles, in particular in models with large engines  where the clutch can be actuated far more comfortably with an SAC.

Clutch Fault Check List

Please check for these faults as fitting a clutch may not solve the problem
1. Clutch Slip
2. Non Clearance, difficulty in engaging gears, clutch fails to release.
3. Vibrant Clutch
4. Noisy Clutch

Clutch release systems

In terms of driving comfort, a driver evaluates the entire clutch and actuation system according to smooth disengagement behavior, the user-friendly force-travel characteristics on the clutch pedal, silent and vibration-free actuation as well as good modulation behavior during startup and gearshift operations. The entire system, from pedal to clutch, must function in all operating conditions and ensure smooth interaction with other vehicle components. Consideration of the entire chain of functions requires sub-functions in the clutch system to be carefully matched to each other. When the clutch pedal is activated, the driver senses the clutch system's response. To satisfy the requirements placed on the clutch pedal, clutch system components must be matched in terms of friction, rigidity and mechanical advantage. The LuK product range comprises all elements for actuating manual transmissions including master and slave cylinders, mechanical lever systems with release bearings, hydraulic clutch release systems for hybrid drives, and engagement systems for wet and dry double clutch actuation systems.

Diaphragm clutch

Combustion engines have a problem: They provide a usable output only in a very specific speed range – just the opposite to electric or steam engines. This means that speed, transferable engine output and gearbox must be optimally synchronised in various drive conditions – this function is provided by the clutch. The clutch separates or connects powertrain from and to the gearbox, which every driver knows from his own experience. When the clutch pedal is depressed, this powertrain is interrupted and a different gear can be engaged. The clutch also enables cars, trucks and other utility vehicles to accelerate away smoothly and without engine bucking.

Clutch pressure plate

Together with flywheel and friction disc, the clutch pressure plate forms a friction system and is mounted to the flywheel by bolts in the housing. The pressure plate ensures that the engine torque is transferred via the friction disc to the transmission intake shaft. In the 70’s, the diaphragm spring clutch has consistently eliminated bolt springs from the passenger car.

Clutch Discs

The clutch disc is the clutch’s central connection element.

In combination with the clutch pressure plate, it both separates and links engine and powertrain. It also reduces the speed fluctuations in the gearbox caused by the combustion motor. LuK offers the best solutions for every application, from clutch discs with simple torsion damper through to variants with multi-stage dampers, from rigid clutch discs for use in the dual mass flywheel right through to the displacement correction clutch disc.

LuK Release bearings

The clutch transfers the power and the release bearing ensures correct function. The release bearing is the connection between the rotating clutch assembly on the engine side and the fixed release mechanism on the transmission side. Trust ball bearings are used to transfer the release loads to the clutch assembly. Modern release bearings are guided on a bushing which is flange mounted on the transmission. The guide sleeve of a release bearing is moved by radial adjustment to guarantee an optimal central position to the diaphragm spring tips of the diaphragm spring clutch when installed. This helps prevent wear in the diaphragm spring finger area.
One in every two new vehicles with clutches now come with a concentric slave cylinder. This combines the clutch slave cylinder and the traditional release bearing in one component.
The release bearing or the concentric slave cylinder should be replaced with every clutch repair.
