High-voltage motor-pump-unit
High-performance suspension system for fully active suspensions
Intelligent hydraulic unit with electric motor
With the high-voltage motor-pump-unit, RAPA Automotive presents the next evolutionary stage of the market-leading electro-hydraulic unit. It is used in fully active chassis control systems in premium vehicles. With the further development towards a high-performance system for high-voltage applications, it is the most dynamic and high-performance system in the international competitive environment. The innovation is considered a global benchmark, particularly in terms of hydraulic performance.
As a compact axle unit, the complex system is impressive in terms of both weight and installation space – significant improvements have been achieved compared to the previous generation:
- Reduction of the length of the axle set by 30
- Savings of 39 % in relation to the weight
These optimizations are decisive criteria, especially with regard to integration in the high-voltage vehicle electrical system.
Customizing
The industry-specific solution can be customized to meet specific customer requirements, enabling smart driving dynamics control for each wheel, for example. It is also possible to configure hardware and software specifically for the intended use and to easily install over-the-air updates (OTA updates) while the vehicle is in use.
While the high-voltage version is currently being customized according to customer requirements, the system is being continuously developed in parallel. In this way, new development stages of the motor-pump-unit can generate progress for future mobility solutions and set new benchmarks.
