The aluminium-carbon rim on an electric race car should be designed to accommodate the drive and braking systems in its center. The bearings used must require very little mounting space and possess a large open center. Plus they need to securely transfer substantial forces and torques.
Franke Wire Race Bearing, integrated directly in the housing components of the rim as double row angular contact ball bearings. The Wire Race Bearing handles the prevalent loads and works independent of the material used in the mating components. The wires and the rolling elements require minimal mounting space.
Space-saving bearing solution with large open center. Its arrangement as double row angular contact bearings permits extremely dynamic movement processes.
