Method for operating electric drive train of work machine, electric drive train for work machine, and work machine
The invention relates to a method for operating an electric drive train of a work machine, an electric drive train for a work machine, and a work machine, in particular a method for operating an electric drive train (11) of a work machine (10), the drive train (11) comprising a work drive (20) having an electric work motor (21) and a travel drive (30) having an electric travel motor (31) and wheels (32), the speed of the work machine (10) is reduced from the outside, and wherein the braking force acting on the wheels (32) by the speed reduction can be smaller than the driving force acting on the wheels (32) by the moment of inertia of the travel motor (31). The method according to the invention is characterized in that, in order to reduce the rotational speed, an electric current (300, 301) is applied to the travel motor (31) in the opposite direction to the direction of travel thereof when the braking force acting on the wheel (32) by decelerating is detected predictively by means of the situation detection as less than the driving force acting on the wheel (32) (200). The invention also relates to a corresponding electric drive train (11) and a corresponding work machine (10).
用于运行作业机械的电的驱动系的方法、用于作业机械的电的驱动系和作业机械本发明涉及用于运行作业机械(10)的电的驱动系(11)的方法，其中，驱动系(11)包括具有电的作业马达(21)的作业驱动器(20)以及具有电的行驶马达(31)和车轮(32)的行驶驱动器(30)，其中，从外部使作业机械(10)减速，并且其中，通过减速作用到车轮(32)上的制动力能小于通过行驶马达(31)的惯性矩作用到车轮(32)上的驱动力。根据本发明的方法的特征在于，当借助状况检测预见性地识别出通过减速作用到车轮(32)上的制动力小于作用到车轮(32)上的驱动力时(200)，为了降低转速而向行驶马达(31)加载与其运行方向相反的电流(300、301)。本发明还涉及相应的电的驱动系(11)和相应的作业机械(10)。
