Components for electric drive units (EDUs)
A wide range of ElringKlinger components relating to e-motors, transmissions and inverters can be used in an electric drive unit. The design and materials of all our product solutions are tailored precisely to the relevant requirements – for maximum design freedom and functional reliability.
MetaloBond™ rotor/stator laminated stacks
- Full bonding of the layers ensures optimum sealing function in order to implement directly cooled electric machine concepts
- Improved strength and NVH performance
- Thin sheets possible for even more efficient electric machine operation
- In-house development of adhesive enables maximum flexibility in material selection
- Less pressing strokes required to achieve the stack height due to innovative manufacturing processes
Balancing discs
- Punched/formed part with weight and cost-optimized design
- High precision production process ensures tight tolerances and eliminates secondary processes
- Maximum flexibility with regard to material selection
- Material thicknesses up to 10 mm possible
Planetary carriers
- New method: Planetary gears integrated into shaped sheet metal part
- Weight and cost savings
- High torques and speeds
- Longer service life of the gear wheels
Disc carriers
- High strength for transmission of higher torques
