Next-generation SBW system
Engineers developed a next-generation SBW system that eliminates hydraulics from the cab, creating a quieter and more spacious environment. This innovative system employs a minimized steering wheel or joystick, allowing for improved control and intelligent steering adjustments based on vehicle speed, enhancing the operator’s ability to maneuver machinery precisely.
At the heart of Parker advanced steering solution is the SBW110 valve. This valve outputs steering movements directly to the vehicle’s wheels via a joystick and electronic controllers, providing precise and responsive control. The SBW110 can be configured for both steer-by-wire and electrohydraulic (EH) systems, offering versatility and ensuring safety with maintained steering functionality and robust fault management.
Key technological features of the system include dual controllers and independent hydraulic circuits, which provide fault tolerance, and the IQAN-MC41FS controllers, which are SIL2 safety-certified. These controllers, programmed with the IQAN design tool, simplify application development, reducing development time and enhancing system reliability.
Benefits
The benefits of the Parker SBW system are significant for both OEMs and equipment users. For OEMs, the system offers a space-saving design by minimizing hydraulics within the cab and eliminating the steering column, allowing for smaller steering input devices such as a joystick or electric steering wheel. The system’s scalability and modularity make it suitable for various applications and compatible with autonomous machinery technology. For equipment users, the SBW system enhances functional safety with improved stability control and braking distance, increases productivity through precise steering movements, and improves the operator experience by reducing cabin noise, operator fatigue, and heat output. Additionally, the system improves visibility and ergonomic design with customizable driver controls.
Overall, The Parker SBW system represents a superior alternative to traditional hydraulic steering systems, meeting safety standards and offering better efficiency, control, and operator comfort in mining equipment.
