The goal of this master's thesis was to design a propulsion module of an M2 category modular electric vehicle. The paper gives an overview of vehicle categories with a brief description of M2 category. Existing vehicles of a similar purpose and design that can be found on the market are presented, with a presentation of one vehicle platform that is still in R&D phase. Designed concepts of the propulsion module are shown and they are evaluated in three categories of criteria, and each criterion was associated with an appropriate weighting factor. According to the evaluation criteria, the concept that had the highest overall grade was selected, taking into account the weighting factors which were used for grade correction. The concept that received the highest grade was further developed. The paper presents the details of the structural design where special attention is paid to the load – bearing structure (chassis) and the ways of mounting suspension components to the chassis. Two conceptual solutions for joining the steel structure of the propulsion module and composite structure of the middle module are given. Calculations of highly – stressed suspension components and ways of joining them to the chassis is presented. A detailed 3D model was made and an assembly drawing with details is shown.
