Implements take the lead in work processes and demand optimum hydraulic efficiency for the respective work process. With the following era of hydraulic programs, Bosch Rexroth has persistently developed this method and opens up new levels of freedom with Digital load sensing ELS. Due to the eOC (digital Open Circuit) variable piston pumps, the hydraulic efficiency could be flexibly tailored to the necessities of assorted implements. The benefits for the end-user: simplified operation, extremely automated workflows with constant and even higher high quality, and better productiveness with improved power effectivity.
To this point, the hydraulic necessities of implements have normally been despatched to the tractor hydraulics by way of hydraulic load sensing pilot traces. With Digital load sensing ELS, all customers digitally on the similar time talk their necessities for stress, oil stream, and response time to the BODAS management unit. The Software program working on the BODAS management unit controls then the electronically managed variable displacement piston pump (eOC-P) in response to the demand values in an electronical closed loop.
Optimum situations for extremely automated work
In distinction to earlier ideas, Digital load sensing ELS hydraulic programs aren’t restricted by a pump factory-setup. With eOC, Bosch Rexroth shifts the variance into Software program. This shortens engineering instances for machine producers and saves set up house by eliminating beforehand needed hydraulic traces and parts. Above all, the respective implements now decide the tractor pump stress, oil stream, and response instances, thus making certain optimum work outcomes. On the similar time, the superior eOC system method, that includes pumps, ECUs, and electro-hydraulic valves, establishes the muse for future extremely automated operations, like baling. Right here, TIM-capable attachments mechanically guarantee the precise adherence to the diameter and weight of the bales and mechanically cease the tractor to deposit the bales.
Increased power effectivity and availability
The eOC system mechanically compensates for line losses to extend productiveness. The diminished energy loss in standby and the adjustable stand-by stress enhance power effectivity and scale back working noise. Due to the Digital load sensing ELS system structure the stress indicators from all parts are digitally acquired and digitally despatched to the electronically managed pump. With the acquisition of Hydraforce in 2023, Bosch Rexroth affords now an intensive program of compact valves that completes the hydraulic tractor’s system in a space-saving and environment friendly method. Bosch Rexroth thus gives essentially the most complete vary of movement management programs, which incorporates hydraulic screw-in cartridges, manifold blocks, and digital controls with corresponding software program.
A full eOC hydraulic system structure, allow machine producers to develop new analysis and repair methods of the hydraulic system. If required, eOC pumps could be set as much as new parameters over the air.
