Implements take the lead in work processes and demand optimum hydraulic efficiency for the respective work process. With the subsequent technology of hydraulic methods, Bosch Rexroth has constantly 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 might be flexibly tailored to the necessities of varied implements. The benefits for the end-user: simplified operation, extremely automated workflows with constant and even higher high quality, and better productiveness with improved vitality effectivity.
So far, the hydraulic necessities of implements have normally been despatched to the tractor hydraulics by way of hydraulic load sensing pilot strains. With Digital load sensing ELS, all customers digitally on the identical time talk their necessities for strain, oil movement, and response time to the BODAS management unit. The Software program operating on the BODAS management unit controls then the electronically managed variable displacement piston pump (eOC-P) in accordance with the demand values in an electronical closed loop.
Optimum situations for extremely automated work
In distinction to earlier ideas, Digital load sensing ELS hydraulic methods should not 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 vital hydraulic strains and elements. Above all, the respective implements now decide the tractor pump strain, oil movement, and response instances, thus making certain optimum work outcomes. On the identical 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.
Larger vitality effectivity and availability
The eOC system mechanically compensates for line losses to extend productiveness. The decreased energy loss in standby and the adjustable stand-by strain enhance vitality effectivity and cut back working noise. Due to the Digital load sensing ELS system structure the strain indicators from all elements are digitally acquired and digitally despatched to the electronically managed pump. With the acquisition of Hydraforce in 2023, Bosch Rexroth gives 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 probably the most complete vary of movement management methods, 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 prognosis and repair methods of the hydraulic system. If required, eOC pumps might be set as much as new parameters over the air.
