Herlitzius","doi":"10.51202/9783181023617-119","DOIUrl":"https://doi.org/10.51202/9783181023617-119","url":null,"abstract":"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. The aim of the project is to develop a variable and easily controllable implement drive, which allows to operate the i","PeriodicalId":106789,"journal":{"name":"LAND.TECHNIK AgEng 2019","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133265322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":106789,"journal":{"name":"LAND.TECHNIK AgEng 2019","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124953357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
