At Hannover MESse 2023, Bosch Rexroth introduced a number of open, easily integrated automation solutions and will continue to drive the digital transformation of mechanical engineering. In the field of hydraulic technology, Bosch Rexroth is transferring more functions to software. The solution uses open standards to provide greater freedom for machine manufacturers and end users, while reducing energy and resource consumption during use.

Automation: Increase openness while reducing energy and resource consumption
In the past, it was common for automation manufacturers to tightly tie software functions to control hardware, thereby binding customers to their product portfolios. Bosch Rexroth’s Linux-based real-time ctrlX OS operating system was also initially available only on the ctrlX CORE control system, but is now a standalone solution for industrial environments. The ctrlX OS seamlessly connects more AUTOMATION components to the full range of ctrlX AUTOMATION’s portfolio, including partner solutions from the ctrlX World, in a real-time, hardware-independent manner. This makes it even easier and more flexible for machine manufacturers and system integrators to develop, install, update, and operate software-based functions on control systems at all levels of the automation topology. WAGO is the first system and technology partner to install ctrlX OS on its own equipment and is working with Bosch Rexroth to develop new industry-specific solutions.
The ctrlX AUTOMATION toolkit is also driving the sustainable development of industrial automation. More and more energy saving features are applied, such as the intelligent energy mode in the servo drive to ensure that energy is stored in the system in an intelligent manner and peak loads are avoided as much as possible. As an integral part of the recycled product program, it has also become a trend to carry out automated component reuse projects. For example, through professional repair and replacement of worn parts to restore the old servo motor as new, and provide warranty services. About 75% of the components can be reused, resulting in resource savings.

Linear drive technology: Customized solutions for faster access
In the field of linear drive technology, Bosch Rexroth is accelerating the engineering efficiency of individual components and intelligent electronic systems through digital tools. With the help of the virtual assistant, the preset operating software can effectively save the debugging time of the subsystem. As a plug and play solution, Smart Function Kits for stamping and connecting, handling and dispensing simplify and speed up the operational efficiency of the entire process. With pre-built software, subsystem debugging time can be reduced by up to 80%, and visual sequence programming with drag-and-drop blocks can save even more time. Smart Flex Effector opens up a new free space in the field of automation. The sensor-based compensation module uses an independent kinematic mechanism with six degrees of freedom to give the robot the sensitivity of a human hand. This innovative product has been awarded the Hermes Prize 2023.
The product design of Bosch Rieler linear drive technology allows for longer lubrication intervals and better use of lubricants, thereby reducing operating costs and resource consumption throughout the life cycle.
Hagglunds quantum motor series: A new peak in performance and service life
The new Heglon family of quantum hydraulic motors overcomes previous physical limitations and offers a unique combination of torque and speed. With a maximum speed of more than 150 rpm and a maximum torque of more than 350 kNm, it rewrites the rules of power density. Through design and material optimization, the Hegron series is more efficient than previous series, and the average service life has been increased by two times. These motors are suitable for use in equipment such as crushers and mixers, as well as in travelling machinery.
eOC Hydraulic Systems: Provide greater flexibility for walking and securing machinery
Bosch Rexroth presents a new eOC (electronically Controlled Open Circuit) hydraulic system based on the market recognized and electromechanical optimized open hydraulic pump. With these hydraulic pumps for walking machinery and industrial applications, eOC technology allows variable pressure, flow and power operation in stationary and walking machinery applications, thereby increasing the stability of the function in the specific application. The components are more efficient and the overall system is more efficient. At the same time, the adoption of energy recovery solutions becomes possible or can be simplified. The key is to move the complex control process from the hardware controller to the software level, thereby reducing the variety of pump controls and default Settings. Each machine only needs to be set up once, thus reducing the amount of setup work.

eLION Platform: Bosch Rexroth continues to push forward the technology of electrification of walking machinery

Developed specifically for a wide range of off-road applications, the modular eLION platform supports the full electrification of walking machinery. The motor has a rated power range of 20 to 200 kW, with peak power up to 400 kW. ISO 13849 functional safety compliance and full integration of functional safety features help save engineering time. The eLION portfolio includes motors and inverters as well as important system components such as DC/DC, on-board chargers and high-voltage cables. Bosch Rexroth has also equipped the entire eLION platform with BODAS software modules, matching gearboxes and hydraulic components such as axial piston pumps. Various Elion-equipped machines have been put into use in pilot projects.
