Implements take the lead in work processes and demand optimum hydraulic efficiency for the respective work process. With the following technology of hydraulic techniques, Bosch Rexroth has constantly developed this strategy and opens up new levels of freedom with Digital load sensing ELS. Because of the eOC (digital Open Circuit) variable piston pumps, the hydraulic efficiency may 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 power effectivity.
So far, the hydraulic necessities of implements have normally been despatched to the tractor hydraulics through hydraulic load sensing pilot traces. 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 working on the BODAS management unit controls then the electronically managed variable displacement piston pump (eOC-P) in line with the demand values in an electronical closed loop.
Optimum circumstances for extremely automated work
In distinction to earlier ideas, Digital load sensing ELS hydraulic techniques should not restricted by a pump factory-setup. With eOC, Bosch Rexroth shifts the variance into Software program. This shortens engineering occasions for machine producers and saves set up house by eliminating beforehand crucial hydraulic traces and elements. Above all, the respective implements now decide the tractor pump strain, oil movement, and response occasions, thus making certain optimum work outcomes. On the identical time, the superior eOC system strategy, that includes pumps, ECUs, and electro-hydraulic valves, establishes the muse for future extremely automated operations, like baling. Right here, TIM-capable attachments routinely guarantee the precise adherence to the diameter and weight of the bales and routinely cease the tractor to deposit the bales.
Greater power effectivity and availability
The eOC system routinely compensates for line losses to extend productiveness. The lowered energy loss in standby and the adjustable stand-by strain enhance power effectivity and scale back working noise. Because of 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 essentially the most complete vary of movement management techniques, 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 may be set as much as new parameters over the air.
