In standard tractors, the mechanical PTO is used to drive high power demanding implements. Its current design as a mechanic, manually switchable transmission enables efficient power transmission, but does not provide the variability needed for automated optimization of the operating points of the engine and the implement. In this paper the development and testing of an electro-mechanic power spilt transmission as PTO drive for agricultural machinery is being presented. This transmission offers variable speed control with efficiencies of 90% in the main operating range. Introduction The mechanical power take-off shaft has established itself in standard tractors for driving agricultural implements. Two nominal speeds, 540 and 1000 rpm, are mainly used for power transmission. Up to two additional stages offer these speeds at reduced engine speed in order to reduce fuel consumption and noise emission during partial load operation [1]. However, in order to adapt the attachment speed continuously and automatically to changing environmental conditions during operation or to stop it during the turning manoeuvres on the headland an infinitely variable transmission is required. Due to the mechanical coupling between PTO and engine, the speed adaption can only be met by actively adjusting the engine speed of the tractor [2]. This is not only less practicable, but also prevents the optimisation of the whole working combination’s operating point. Variable-speed drive concepts for attachments offer great potential for improvement with regard to the efficiency and quality of the working process. As an alternative to the established mechanical drives, hybrid and fully electric drive concepts for implements are being tested increasingly. Due to the good controllability of electric drives, this drive technology is suitable for various applications such as fertilizer spreaders, VDI-Berichte Nr. 2361, 2019 119 https://doi.org/10.51202/9783181023617-119 Generiert durch IP '54.70.40.11', am 24.05.2021, 02:44:44.

Since established standard tractors do not have the correspondingly powerful electrical energy sources and are therefore not suitable for the conversion-free operation of electrical attachments, only a few electrical attachments exist so far [3]. Approach In order to both eliminate the speed coupling of the combustion engine to the implement and to offer a retrofittable electrical power source for tractors, a joint research project carried out by Müthing GmbH & Co. KG and Pulsgetriebe GmbH & Co. KG with the Professorship for Natural Materials Technology of TU Dresden and the Institute for Machine Elements and Systems Engineering of RWTH Aachen University developed an electric power-split transmission for the power take-off drivetrain.

在标准拖拉机中,机械PTO用于驱动高功率要求的工具。它目前的设计是机械式的、手动切换的变速器,可以实现高效的动力传输,但不能提供发动机和执行器操作点自动化优化所需的可变性。本文介绍了一种用于农业机械PTO驱动的机电动力分流传动的研制和试验情况。该变速器提供变速控制,在主要操作范围内效率为90%。机械动力输出轴在农机具驱动的标准拖拉机中占有重要地位。两种标称转速,540和1000转,主要用于动力传输。为了减少部分负荷运行期间的燃油消耗和噪音排放,在降低发动机转速的情况下,多达两个额外的级提供这些速度[1]。然而,为了在操作过程中连续和自动地适应不断变化的环境条件,或在岬角转弯时停止它,需要无级变速传动。由于PTO与发动机之间存在机械耦合,因此只能通过主动调节拖拉机发动机转速来满足速度适应[2]。这不仅不可行,而且妨碍了整个工作组合工作点的优化。变速驱动概念的附件提供了巨大的潜力,以提高工作过程的效率和质量。作为现有机械驱动的替代方案,混合动力和全电力驱动的概念正在越来越多地进行测试。由于电驱动的良好可控性,该驱动技术适用于各种应用,如化肥撒布机,VDI-Berichte Nr. 2361, 2019 119 https://doi.org/10.51202/9783181023617-119 Generiert durch IP '54.70.40.11', am 24.05.2021, 02:44:44。Das Erstellen和Weitergeben von Kopien dieses pdf第一晚zulässig。播种机或马铃薯收割机。由于现有的标准拖拉机没有相应的强大的电能来源,因此不适合电气附件的无转换操作,迄今为止只有少数电气附件存在[3]。方法:为了消除内燃机对机械的速度耦合,并为拖拉机提供可改装的电力电源,由德国m thing有限公司和德国Pulsgetriebe有限公司共同开展的一项联合研究项目,由德累斯顿工业大学天然材料技术教授和德国亚琛工业大学机械元件与系统工程研究所共同开发了一种用于动力输出传动系统的电力分路传动系统。该项目的目的是开发一种可变且易于控制的执行驱动器,该驱动器允许在不改变拖拉机发动机速度的情况下以最佳速度操作执行器。为此,变速器配备两台电机,作为发电机-电机组合用于无级变速传动。两者也可以用作发电机,以电力驱动的工具或作为附件的驱动电机。分功率传动结构,减少了需要安装的电机功率,从而可以使用更小、更经济的机组。此外,紧凑的高速机器,运行速度超过10,000转/分钟,允许紧凑的设计和有竞争力的成本。如图1所示,共有四种工作模式。无级可变PTO允许PTO速度独立于拖拉机发动机转速在0和1090 rpm之间进行控制。牵引车PTO的主要工作范围为800 ~ 1000转/分,这样可以优化发动机的工作点。发电机模式可用于为当前拖拉机配备电力接口。混合模式同时提供可变PTO和电气接口。为了驱动局部无排放的机械装置,该装置也可以用作使用外部电源的电动机。

Current concepts of agriculture equipment are characterized by a high level of productivity and mechanization. At present, dimensions and weight of tractor – implement systems are the most important limitations for growing productivity. Modular and scalable systems with a high and variable degree of autonomy try to address the abovementioned challenges with the goal to deliver configuration capability regarding actual task and field conditions providing greatly increased scalability of peak performance, productivity and economy. Possible machine concepts can consist of a tractor with an intelligent and modular (tillage) unit and/or autonomous self-propelled systems working as single unit or in a swarm. Swarm operation requires an adaptive and multimodal frontend to manage and lead a heterogeneous swarm of smart implements. The modularization of the tillage system requires defined spaces for a large variety of tools, component parts and storage capacities. In addition, the interfaces for mechanical connection, power transmission and data transfer need to be developed. The conceptual idea and prototype modules are explained and potential and challenges of the idea is evaluated.
