Manufacturers of mobile machines must decide whether to control their pumps using pressure, torque or swivel angle — and always have to accept compromises as a result. The same applies to numerous other hardware parameters which, once defined, stay the same throughout a machine’s service life.

According to Simon Dreher, an excavator industry specialist with the Mobile Hydraulics Group at Bosch Rexroth, Lohr am Main, Germany, today’s hydraulic systems mainly rely on pure hydro-mechanically controlled components like pumps, joysticks or valves. “We all know that for every single machine, this takes installation and hardware effort in combination with poor flexibility because once the machine’s behavior has initially been set, it can usually not be changed, or only with manual effort,” he said.

A better alternative, said Dreher, is electronification of hydraulic components. It lets OEMs build a machine with simple and flexible hydraulic functions, combine the best of open-center and flow-sharing in one software platform, and manufacture only single type of machine that can be preset one way or another, according to the customer’s choice, without compromises.

A new electrohydraulic system moves control functions from the hydromechanical controller to software. The Rexroth eOC (electronic Open Circuit) portfolio includes software and hydraulic components for dynamically controlling work applications and travel drives. Controlled via a CAN interface, eOC software makes it possible to set various control parameters flexibly during operation. With hydromechanical control functions and interfaces moved to the software, control modes can be individually changed and combined during operation and pump dynamics can be variably set.

“Today, for different applications, different tasks and different control strategies, we have a wide range of hydromechanical controllers. These often come in combination and therefore are cost intense. Finding the right setting for each controller has always been a compromise. And once a setting has been defined, this could not be changed in the field. With eOC, we have now managed to transfer all of today’s pump control functions into software. This enables better control quality and unlimited flexibility to achieve extremely individual machine settings,” Dreher explained. “And what’s more, parameters can be changed on an incremental scale by the operator, right in the cabin.”

With electronic closed-loop control, the BODAS eOC pump control software requires an electrohydraulic control valve on the pump, a swivel angle sensor, and pressure sensor on the pump outlet. For electronic load sensing, an additional pressure sensor for the load pressure must be installed at the LS port of the main control valve. The software itself runs on a dedicated control unit and processes pressure, swivel angle and rotational speed information. And as an output, it generates a PWM current for the pump control valve.

Thus, pressure, torque, flow and swivel angle are controlled independently of each other in an electronically closed control circuit, so the pump behaves optimally as part of the entire hydraulic system. And because the eOC architecture allows for dynamic control of pressure, swivel angle and torque gradients, it enables much smoother and gentler motion, especially at the start of a movement. Via the CAN bus interface, setpoint values and parameters can also be adjusted dynamically to allow additional functions and to adapt machines to cope with specific customer requirements and work tasks.

The eOC software can be installed on a Rexroth BODAS controller or a third-party controller. It constantly adapts hydraulic power to the available engine torque and thus allows dynamic, precise work functions, which ultimately increase the overall productivity of the machine. It optimizes energy consumption of the entire hydraulic system, resulting in lower fuel consumption or, in the case of electrified machines, better battery use.

As a scalable solution, the Rexroth eOC portfolio allows step-by-step implementation — from the electrohydraulic eOC pump to the option to cover the entire hydraulic system, including an eOC main control block and an electric joystick.

Auto-calibration, where a component calibrates within the machine itself, is another new eOC function. Instead of performed statically at the end of an OEM’s production line, calibration is instead carried out cyclically while the machine operates. The eOC software records specific calibration information at start-up and during operations. Up-to-date data which, for example, take into account aging effects or temperature differences, are recorded and parameters automatically adjusted accordingly. This increases the reproducibility of behavior, enables full use of pump power at all times, and supplies precise pump status information for further processing on the machine level.

The Rexroth eOC architecture also allows a new approach when it comes to travel drive systems, especially for compact machines. Based on a secondary control concept, the eOC combines the functionality of a closed-circuit travel drive with the physical layout of an open-circuit drive which only requires one pump for travel and working functions.

As a result, all travel and work functions can be combined in one hydraulic circuit — all rotating consumers are connected directly to the pressure line. A secondary logic system with no additional directional valves controls the hydraulic motor displacement and output torque to achieve the desired rotational speed.

The eOC travel concept requires fewer components and simplifies the hydraulic architecture, as travel direction valves and brake valves are no longer needed. In addition, the combination of working and travel functions in one hydraulic circuit allows the recovery of hydraulic energy during braking or lowering and, thus ensures, that the optimum use is made of the drive power.

The 4000-series Massey Ferguson, 9000-series Case IH, most Versatiles (including Ford-Versatile designation 6 models and 1150"s), and several Steigers (with Cummins or Cat engines), can all be upgraded with Atom-Jet"s standard open-center system. The bolt-on upgrade kit provides one dedicated high-flow circuit over and above the tractor"s existing system. With variable flow rate control of 13 to 26 gpm at 2,000 psi, (controlled by a toggle switch in the cab), you can optimize engine rpm and fan speed, boosting hydraulic power for running high-flow implements such as air seeders.

"Installation on Versatiles involves drilling some mounting holes for the pump bracket and making sure the pulley alignment between the crankshaft and the pump is accurate. We have various different ways of mounting on other makes of tractors," says Curtis Gouldie, Hydraulic Specialist with Atom-Jet. "In the typical installation for most other models, the kit"s auxiliary pump is driven off the front of the engine and mounts below the crankshaft pulley. A front-mounted 30-gal. oil reservoir offers a dedicated fluid supply."

"If you require active down pressure, want to pull an air seeder with dual fans, or have variable rate technology, our closed-center kit will fit the bill," Gouldie says. "It"s a load-sensing system that boosts maximum flow to 40 gpm with a 3,000 psi rating. It has an in-cab, electric, proportional joystick, so you don"t have to plumb hydraulic lines into the cab. It"s also much quieter."

Manufacturers of mobile machines must decide whether to control their pumps using pressure, torque or the swivel angle – and must compromise as a result. The same applies to numerous other parameters which are defined once for the hardware and continue throughout the machine’s service life. The new electrohydraulic solution from Bosch Rexroth solves this problem by moving control functions from the hydromechanical controller to the software. This makes machines even more versatile and flexible. In addition, machines benefit from increased productivity and lower energy consumption.

The electrohydraulic eOC pump with swivel angle sensor and pressure sensors is the central component in the eOC architecture. It ensures the proper control of the necessary setpoint values for torque, pressure or flow. The pump provides highly dynamic control with millisecond accuracy to modulate the pressure. In combination with the eOC software, characteristics such as dynamics and power control can be set, changed and combined.

Controlled via a CAN interface, the eOC software makes it possible to set various control parameters flexibly during operation. With hydromechanical control functions and interfaces moved to the software, control modes can be individually changed and combined during operation and the pump dynamics can be set variably. Pressure, torque, flow and the swivel angle are controlled independently of each other in an electronically closed control circuit. With predefined parameters, the pump behaves optimally as part of the hydraulic system regardless of function. Via the CAN bus interface, setpoint values and parameters can also be adjusted dynamically to allow additional functions and to adapt machines to meet specific customer requirements and complete various work tasks.

The eOC software can be installed on a Rexroth BODAS controller or a controller from a third-party manufacturer. It constantly adapts the hydraulic power to the available engine torque and thus allows dynamic, precise work functions, which ultimately increase the overall productivity of the working machine. The energy consumption of the entire hydraulic system is optimized, resulting in lower fuel consumption or better battery use.

Mass-produced machines already benefit from the new hydraulic architecture. They include a compact excavator which entered mass production in the first half of 2021. A power mode for demanding excavation work was developed for this purpose. This operating mode allows maximum pressure and torque as well as maximum pressure gradient dynamics, for example when emptying the shovel. The machine also has a fine mode allowing jerk-free, smooth operation, in applications such as laying pipes.

As a scalable solution, the Rexroth eOC portfolio allows step-by-step implementation – from the electrohydraulic eOC pump with swivel angle sensor and pressure sensors to the option to cover the entire hydraulic system. An eOC main control block and an electric joystick are provided for this.

Bosch Rexroth has now upgraded a wide range of axial piston pumps and added numerous new functions to the existing basic concept. For example, the eOC architecture now allows the dynamic control of pressure, swivel angle and torque gradients. This means that the pump not only reaches a specific target value – the pressure gradients that are needed to achieve this pressure are also determined. This allows much smoother and gentler motion, especially at the start of a movement.

Auto-calibration, where the component is calibrated within the machine itself, is another new eOC function. Calibration therefore no longer takes place statically at the OEM’s end of production line – it is instead carried out cyclically while the machine is operating. The eOC software records specific calibration data every time the machine starts. Other data is recorded whenever the machine’s operating conditions allows. In this case, up-to-date data – which take into account aging effects or temperature differences, for example – are recorded and the parameters are automatically adjusted. This increases the reproducibility of behavior, full use is made of pump power at all times and the pump status information for further processing on the machine level is as precise as possible.

The Rexroth eOC architecture not only opens up new possibilities in the area of working hydraulics – it also allows a new approach when it comes to the travel drive systems of compact machines. The eOC functions in accordance with the secondary control concept, combining the functionality of a closed-circuit travel drive with the physical layout of an open-circuit drive, which only requires one pump for travel and working functions.

As a result, all travel and working hydraulics functions in compact machines can be combined into one hydraulic circuit – all rotating consumers are connected directly to the pressure line. A secondary logic system with no additional directional valves controls the hydraulic motor’s displacement and output torque to achieve the desired rotational speed. The eOC travel concept requires fewer components in the machine and simplifies the hydraulic architecture. Complexity in the hydraulic system is moved into the software. Travel direction valves and brake valves are no longer needed. In addition, the combination of working and travel functions in one hydraulic circuit allows the recovery of hydraulic energy during braking or lowering, thus ensuring that the optimum use is made of the drive power.
