BG-AUX-EPS-HEAVY is a heavy-duty Electric Power Steering (EPS) rack series developed for commercial vans, electric buses, and high-load vehicle platforms. The series includes multiple rack configurations supporting various body widths, steering layouts, and vehicle architectures while sharing a common steering technology platform.
Delivering steering forces from 11 kN to 18 kN, the series supports both pinion-assist and rack-assist architectures for medium- and heavy-duty commercial vehicles. Multiple DC12V and DC24V configurations enable seamless integration into a wide range of fleet and public transportation applications.
Designed for demanding commercial vehicle duty cycles, BG-AUX-EPS-HEAVY provides reliable steering assistance, flexible vehicle integration, and compatibility with emerging autonomous and steer-by-wire vehicle platforms.
