MULTIPLE LEVEL WORK HYDRAULICS ANTI-STALL

WIPO Patent Application WO/2018/085974

A1

A power transmission arrangement (10) for a construction vehicle (1), comprising an engine (4), a hydraulic power system (12, 13) for powering work hydraulics (7, 8) of the construction vehicle (1), which is feedable with power from the engine (4), the hydraulic power system (12, 13) including a power limiter (17) for limiting the power supply of the engine (4) to the hydraulic power system (12, 13) to different power limit values, a drivetrain power system (11) for powering locomotion of the construction vehicle (1), the drivetrain power system (11) being feedable with power from the engine (4), a determining device for determining an operational state of the construction vehicle (1), and a controller (22) configured to control the power limiter (17) to limit the power supply of the engine (4) to the hydraulic power system (12, 13) to different power limit values, these power limit values being set depending on the operational state of the construction vehicle (1) determined by the determining device. Furthermore, a construction vehicle (1) including such a power transmission arrangement (10) and a method of controlling such a power transmission arrangement(10).
