Description
This component is the final gear in a transmission of an electric bike drive unit.
The product, which was designed specifically as a powder metal solution, integrates a number of functional properties within one single component:
- Transmission of torque from outer teeth to output hub
- Precise inner bore for needle roller bearing
- Complex geometric features for accommodating damping rubber elements and the direction sensor module
- Distinctly reduced NVH emissions compared to previous drive generation for pleasant drivers' experience by applying optimized gear profile
- High strength material for demanding torque transfer capability and extended wear resistance
- 10% less weight compared to a gear from wrought steel
- Approx. 50% cost reduction compared to a steel solution.
