TriFinity™ Wheel Bearing of the 3rd Generation
Wheel bearings play a vital role in passenger cars by managing the complex interplay of moving parts. They transmit torque with minimized friction, provide the ABS signal, ensure wheel guidance and direct wheel control. This technical solution is important for maintaining vehicle efficiency and prolonging the lifespan of passenger cars.
Highlights
- High performance grease for friction reduction
- Face Spline design with up to 50% higher torque at same dimensions, best NVH performance, and reduced weight
- Low weight components and sustainable steel
Advantages
Using TriFinity™, you profit from a range of options:
- Higher load density:
- Higher stiffness of ~33 %/less deflection
- Increase in load capacity of ~24 %
- Design substitution with a change from tapered roller to ball design
- Same envelope dimensions
- Friction reduction of up to 53 %
- Reduction of electric consumption per vehicle, e.g. via downsizing on front axle and design substitution on rear axle:
- ~0.7% (FTP75 cycle)
- ~0.5% (HWFET cycle)
- Downsizing with reduced dimensions and ~19 % less friction
