FAG wins 2008 Automechanika Innovation Award in the parts category

In conventional systems, the drive torque is transferred between the wheel bearing and the axle journal by means of radial splines, which have a certain amount of clearance to make mounting easier. Loads that occur in day-to-day driving conditions mean that there is a risk that the assembly constantly loosens way beyond the normal mounting clearance, resulting in everything from losses in comfort and uncomfortable noises, right up to the failure of the bearing. However, the new FAG wheel bearing module with axial splines is appealing due to simple mounting methods. The self-centring axial gear teeth are placed on the axle journal and fixed in placed by means of the central screw in the assembly. The bearing remains completely clearance-free in the gear teeth during operation. A reduction in weight in the new FAG wheel bearing concept of around ten percent amounts to a reduction of more than a kilogram overall for all four wheels in the vehicle, which contributes to a reduction in fuel consumption and therefore a reduction in damaging CO2 emissions. In addition, considerably simplified mounting procedures can be used that offer a significant advantage over conventional radial gear teeth. The economical production of these axial splines first became a reality when an orbitally-formed shoulder was used as a carrier for the gear teeth. As early as 1989, FAG axially fixed the bearing inner ring with the orbitally-formed shoulder, thereby eliminating the screw fixing common at that time. In the new wheel bearing concept, the axial splines are applied onto the orbitally-formed shoulder by high-precision cold forming. A comprehensive series of tests has shown that the torque transmission with the axial splines is considerably higher compared with radial splines, mainly due to the larger diameter of the pitch circle of the gear teeth. With its brands LuK, INA and FAG, the Schaeffler Group is a hallmark for pronounced customer orientation, innovative power and superior quality. In 2007, 66,000 employees at over 180 locations achieved a sales volume totalling 8.9 billion euros. The Schaeffler Division Automotive is a specialist supplier of drive train components and services for passenger cars (PC) and commercial vehicles (CV): from engine and accessory drive to transmission and suspension. The worldwide automotive aftermarket sales business of the LuK, INA and FAG product brands is run by Schaeffler Group Automotive Aftermarket based in Langen, Germany. The company has established a global network of approximately. 11,500 distribution partners, thereby remaining close to its customers for more than 30 years.
