In dieser Arbeit wird die Auslegung eines Planetengetriebes als Radnabenmotorkonzept für einen Formula Student Rennwagen erläutert. Als Grundlage dafür dienen die bereits entwickelten und gebauten Fahrzeuge, insbesondere der Cr120 und der elektrifizierte Cr115e, des Os.Car Racing Teams der FH Campus Wien. Der Umstieg des Teams auf ein elektrisches Antriebssystem steht bereits fest und ist lediglich eine Frage der Zeit, weshalb für diesen Bereich sehr viel neues Wissen erworben und aufgearbeitet werden muss. Deshalb beschäftigt sich diese Arbeit in einem großen Umfang damit, welche Antriebskonzepte und Möglichkeiten der Umsetzung es gibt und zeigt ein selbstentwickeltes Radnabenmotorpaket, welches eingesetzt werden kann. Den Ausgangspunkt bildet eine umfassende Recherche über die Formula Student Electric allgemein, sowie eine Analyse der Top 20 Teams in der Weltrangliste. Anhand dieser Auswertung sind klare Trends, sowie funktionierende Konzepte und Konstruktionen gut zu erkennen, an welchen sich die Eigenentwicklung, neben Wissen aus Fachbüchern, orientiert. Als Antrieb für das ausgelegte Radnabenmotorkonzept wird das AMK „Racing Kit“ mit vier AMK DD5 Synchron-Servomotoren verwendet, welche an der Innenseite der Radträger befestigt sind. Das 1½-stufige Planetengetriebe, mit einer Übersetzung von 1:14, ist komplett in den Radträger integriert und sorgt für ein Moment von bis zu 294 Nm pro Rad. Neben der Gesamtkonstruktionsübersicht und einem Einblick in die einzelnen Komponenten, wird die Integration in ein bestehendes Fahrzeugkonzept des Teams behandelt und ein abschließendes Fazit, sowie ein möglicher Ausblick gegeben. This thesis deals with the design of a planetary gear as a wheel hub motor concept for a Formula Student racing car. The vehicles that have already been developed and built, in particular the Cr120 and the electrified Cr115e, of the Os.Car Racing Team at the FH Campus Wien serve as the basis for this. The teams' switch to an electric drive system has already been decided and is only a matter of time, which is why a lot of new knowledge must be acquired and processed in this area. Therefore, this thesis deals to a large extent with which drive concepts and possibilities of implementation there are and shows a self-developed wheel hub motor package which can be used. The starting point is extensive research on Formula Student Electric in general, as well as an analysis of the top 20 teams in the world rankings. Based on this evaluation, clear trends as well as functioning concepts and constructions can be easily recognized, on which the own development is based alongside with knowledge from specialist books. The AMK "Racing Kit" with four AMK DD5 synchronous servo motors, which are attached to the inside of the wheel carriers, is used as the drive for the designed wheel hub motor concept. The 1½-stage planetary gear with a ratio of 1:14 is completely integrated into the wheel carrier and provides a torque of up to 294 Nm per wheel. In addition to the overall design overview and an insight into the individual components, the integration into an existing vehicle concept of the team, a final conclusion and a possible outlook is given.

This contribution deals with the topic of the consistent further development of a wheel hub motor for battery electric vehicles (BEV) based on the principle of an outer rotor switched reluctance machine (SRM). The research work presented in this paper was founded by the ERDF.NRW program, Investment for Growth and Employment and the European Regional Development Fund. The R&amp, D project was named Switched-Reluctance fo(u)r wheel (SR4Wheel). Based on the experience made by first prototype Evolution 0 (EVO 0), developed in the Laboratory for Automation Engineering, Power Electronics and Electrical Drives of the Cologne University of Applied Sciences (CUAS), the test results of EVO 1, as well as the redesign, EVO 2 is presented in this paper. The prototype EVO 0, a first proof of concept leads to several optimizations and lessons learned for the predecessor model EVO 1. The overall target of developing such a gearless outer rotor wheel hub motor is the full integration of the complete machine including its power electronics into the given space between the original friction brake and the rim. Furthermore, due to the additional integration of the power electronics, great opportunities in terms of new vehicle design as well as retrofitting capabilities of already existing vehicle platforms can be achieved. Thereby, further drive train assembly space like the engine compartment is no longer necessary. The SRM does not require magnets for torque production which leads to independence from the changeable commodity prices on the rare earth element markets. This paper presents the developing process, testing, and verification of the innovative drive train concept starting with the final CAD of EVO 1. During the testing and verification process a machine characteristic mapping is performed on a drive train test bench and subsequently the results of a finite element analysis (FEA) are plausibility checked by the test bench results. The process continues with energy conversion test scenarios of the project demonstrator vehicle on a roller test bench focused on noise vibration harshness (NVH) behavior and efficiency. As a conclusion, the gained knowledge by evaluating two EVO 1 prototypes on the rear axle of the test vehicle, and the design for the front axle drive train EVO 2 will be presented. As a major task on the front axle, the limited space due to the large disc brake can be identified and solved.

This paper outlines the development of the ROboMObil, an innovative electro-mobility concept based on intelligent central control of four Wheel Robots, which integrate the drivetrain, brakes, steering and dampers. The motivation behind the Wheel Robot concept, the implementation details together with the suspension design are described. The electric power system, consisting of a Li-Ion battery cluster to provide high-voltage power for propulsion and a low-voltage supply for vehicle control, is also discussed. Finally, we provide an overview of the Shared Autonomy control architecture and an outlook on the future research projects based on this demonstrator platform.
