“The LuK Story. 50 years.
Quality. Technology. Innovation.”
from June 20 to December 20, 2015 at Schaeffler's Bühl location
Our historic exhibition gives customers, business partners, and employees the opportunity to take a walk through our company’s history, which has been shaped by the spirit of invention and desire for progress.
A journey through five decades of LuK, one of the world's largest clutch manufacturers and drive train specialists.
LuK is an integral part of the Schaeffler Group. Over the last five decades, LuK has established itself within the Schaeffler Group as an expert and technology leader in the field of systems and components for vehicle drive trains. It all started in 1965 when the company developed a diaphragm spring clutch with a release system – which to this day remains a groundbreaking innovation and just one of the many to have come from LuK.
The diaphragm spring clutch is the beginning of luK's success story. Beginning in the mid-1960s, it increasingly replaces the coil spring clutch. Engines with higher torques overtax existing technology. Starting in spring 1965, LuK supplies diaphragm spring clutches to Volkswagen for the "Type 3" mid-size model. This makes this company from Bühl the first European high-volume manufacturer of diaphragm spring clutches.
LuK was the first manufacturer in Europe to successfully develop a dual mass flywheel (DMF) for high-volume production. The DMF allows driving in fuel-efficient operating points with increased auditory comfort, and therefore makes a contribution to reducing CO2 emissions and fuel consumption.
An innovation by LuK engineers turns clutches from a wearing part into a permanent solution. This is achieved in the mid-1990s through the self-adjusting clutch (SAC), resulting in a longer life and comfort. When the friction lining of a clutch with diaphragm springs is worn, the SAC adjusts itself. Due to the SAC 1 and the enhanced SAC 2, the feel of the clutch pedal remains consistent. The clutch lasts through a long car life.
This was followed by development of the traveladjusting, self-adjusting clutch (TAC).
Since they were first launched on the market for high-torque applications, the outstanding features of LuK‘s CVT components have gained a substantial reputation among specialists: In addition to their suitability for high-performance gasoline and diesel engines, the widest possible ratio spread and the high efficiency of the variator are the focus of customers‘ attention. LuK’s multi-link chain is now being used in high-volume production by three international vehicle manufacturers in Europe and Asia.
The dry double clutch is an innovative development by LuK with great customer benefit. lt permits a high level of driving and shifting comfort while also reducing fuel consumption. In 2008, it is used for the first time in the VW Golf. Two automatically activated clutches arranged successively transmit the engine torque via two input shafts to the transmission. To shift gears, the clutch that has just transmitted the torque opens, the other clutch closes. Both processes happen automatically within one hundredth of a second and without any noticeable interruption of the tractive force.
The current prototype for the integrated torque converter (iTC) is one of the latest innovations by Schaeffler's LuK brand. lt is being prepared for volume production at the Wooster (US) location where converters are developed from 1996 onwards, like they have been at the Bühl location since 1990.
This hydraulic-mechanical component increases the performance and efficiency of the automatic transmission. lt also reduces fuel consumption and C02 emissions. In this way, Schaeffler supports the automobile industry on its way to more efficient mobility for the future.
