Abstract: In order to ensure the continuity and implementation of the platform, the key dimensions and module interfaces of the front and rear suspension systems are defined. According to the research and analysis of the mainstream models in the market, the performance bandwidth and size bandwidth of the vehicle modular platform are formulated. In the modular design of front and rear suspension systems, the evolution scheme is formulated to meet the development needs of different models. Adopt the modular development mode of automobile, it can effectively reduce the types of parts, shorten the product research and development cycle, reduce research and development costs, and improve product reliability. Finally improving the overall generalization rate of the vehicle.

Key words: McPherson suspension; Multi-link suspension; Modularization; Dimension definition; Interface definition
