Electric E-Axle Actuator (EAA)
The EAA is a powerful linear actuator for the actuation of single- or double-sided shift elements. Originally designed for 2-speed gear shift it is able to serve multiple functions like differential locks, disconnect / decoupling units, park-locks or other mechanic shift elements (fork not included). Due to its non-smart design and clever integration concept, the EAA can be easily re-used for new applications and vehicles with low effort.
Highlights
- Highly integrated design: Saves space and weight
- Radial integration: Reduces integration and assembly efforts
- Very high actuation dynamics: Due to low inertia and powerful BLDC motor performance
Advantages
- High flexibility due to simple interface to shift element (fork, lever or others)
Multiple possible functions and applications - Very low power consumption due to power on demand concept
- Non-smart design with integrated sensor capability up to ASIL C
Control integrated into customer control unit - Possible as 12 V or 24 V variant
