Drivers of manually shifted cars have been familiar with this practice for decades depressing the clutch pedal to engage the next higher gear In most cases a Schaeffler component has a major part in this a clutch from LuK One in three new cars around the globe leaves the as sembly line with a clutch from the Schaeffler brand This success story starts in 1965 with the founding of LuK Lamellen und Kupplungsbau GmbH in Bühl in which Dr Ing Georg Schaeffler and Dr Wil helm Schaeffler have a decisive part As early as in its founding year LuK DECELERATION ASSISTANT THE CLUTCH is the first clutch manu facturer in Europe to introduce the diaphragm clutch that will go on to progressively displace the coil spring types from the passenger car segment In 1974 LuK is the first clutch manufacturer in the world to offer diaphragm spring clutches initially though only for tractors Due to the continuing evolution in ve hicle engineering clutch components today have to meet a wide range of requirements that primarily affect ride comfort such as quick shifting vibration damping and noise reduc tion Schaeffler innovations like the dual mass flywheel or the clutch plate with a torsion damper and cen trifugal pendulum type absorber en sure this as well Modern clutches are characterized in particular by engine speed strength high transmission reliability low installed height low disengagement forces and long life Due to its clutch expertise Schaeffler has evolved into one of the world s biggest manufacturers of friction linings Tens of thousands of linings leave plants in Germany China Brazil and South Africa every day The clutch linings 160 mm to 430 mm 6 29 inches to 16 9 inches outer diameter are used in production by all major automotive OEMs The industrial lin ings are utilized in diverse applica tions ranging from 10 mm 0 4 inch clutch linings in data backup equip ment to segments of a clutch brake combination with an outer diameter of 864 mm 34 inches The demands to be met by the clutch system change due to the electrification of the powertrain Consequently Schaeffler developed a P2 hybrid module with a wet triple clutch system K0 K1 and K2 to production level among other things This system can almost completely be integrated into the rotor of the electric motor and thus into its installed length As a result the entire system consisting of the hybrid module triple clutch and transmission is very compact K1 K0 K2 Talking about ABS Since as early as 1952 a hy draulic brake deceleration system an ABS named Dun lop Maxaret has existed in aviation In initial tests an Avro Canada CF 100 lands safely on ice Today ev ery large aircraft uses three brakes While the plane is still airborne the brake flaps are extended to reduce lift After the aircraft has touched ground reverse thrust is initiated first The turbines rotate in reverse and start braking when a weight greater than 6 300 kilos 13 889 lbs for example on an Airbus 320 acts on both land ing gears Disc brakes in the wheels bring the plane to a halt On the A320 they start working according to plan only at a ground speed of 140 km h 87 mph 2 000 m 6 562 feet is the stopping distance of the Oasis of the Seas cruise ship in case of an emergency That s extremely short says Captain Tor Olsen Extremely short Yes when considering that ships are allowed a stopping distance of 15 to 20 hull lengths Consequently for the 360 meter 1 188 foot Oasis of the Seas up to 7 6 kilometers 4 7 miles would be allowed in other words nearly four times as much as the ship really needs Braking on water is strictly achieved by reversing the direction of the screws 52 53
