Spoke damper on crankshaft
The majority of combustion engines requires a torsional vibration damper to ensure good NVH and lower stresses due to eigenfrequencies of the crankshaft. Many modern engines, especially for hybridized applications, tend to have no FEAD – this is where the spoke damper comes in.
The spoke damper is an innovative concept designed to reduce torsional vibrations of the crankshaft. Since it is optimized to be positioned within the crankshaft housing, it does not require friction-based sealing. Consequently, the spoke damper helps to reduce both friction and axial space requirement.
Highlights
- Durability and function is not influenced by temperature
- Optimized for use inside the crankshaft housing: crankshaft seal can be omitted and friction is reduced
- Pure metal design: easy to recycle together with crankshaft
Advantages
- Optimized for use inside the crankshaft housing
- Damping power and frequency can be flexibly adjusted
Features
- Oil resistant
- High vertical manufacturing depth at Schaeffler, thus low dependency on external suppliers
- Compact and weight optimized design
