FAG Changes the Face of Wheel Bearings
|
gear teeth was initiated in 2004. In the new wheel bearing concept, the spur gear teeth are applied onto the orbitally-formed shoulder by high-precision cold forming. The forming technology experts of the Schaeffler Group have thus found a sophisticated solution for the manufacture of this complex component that allows volume production to the highest standards of quality.
A comprehensive series of tests has shown that the torque transmission with the spur gear teeth is considerably higher compared with conventional radial gear teeth. This is mainly due to the larger diameter of the pitch circle of the gear teeth. This Schaeffler innovation has already been transferred to volume production. Due to their significant advantages, wheel bearings with spur gear teeth will successively replace conventional radial gear teeth. “We are convinced that this groundbreaking invention will sooner or later become established with all automotive manufacturers”, said Dr. Manfred Krauss, Chief Engineer Chassis Applications of Schaeffler Group Automotive. This acclaimed wheel bearing solution, which has won the “2008 Automechanika Innovation Award” and the “2009 NoAE Innovation Award” (Network of Automotive Excellence), is for the first time used in serial applications in the BMW X1. |
