The presented paper introduces a new design of vehicle suspension which was developed in the joint research project of BMW Group Forschung und Technik, DLR and Schaeffler Group. In this suspension the wheel guidance and gearbox are highly integrated thus enabling to place the drive motor close to the wheel and consequently to minimise required space in the vehicle. Therefore, the saved space can be utilized otherwise, e.g. for a battery or an electronics assembly. The paper focuses especially on different aspects of the modelling in the early design stage where the first estimations of suspension characteristics and vehicle handling were performed. This covers the coupling of multibody model of suspension with one-dimensional model of gearbox, spiral spring model or elastokinematic bushings.
