The car chassis is a system that consists of assemblies of the chassis, transmission, and control mechanism. It is one of the most essential parts of a vehicle, as it allows the perception and transmission of all the forces that act on it while driving. Design calculation of the proposed chassis development is aimed at determining the main parameters and calculating parts of the designed unit (system, unit). Automotive chassis engineering covers schemes of forces and moments, as well as the nature of the loads acting on the node during the operation of the vehicle, the strength calculation of the main details of the projected unit; identifying the main node parameters, dimensions of parts, their configurations, relative positions parts and assembly of the unit.
