The research is carried out to improve passenger’s comfort to increase the vehicles stability in dynamicconditions. The literature available in the automotive engineering considers different topics for studying suspensions. Anexample represents mechanisms structure and analysis (synthesis, kinematics, and dynamics) under various operatingconditions. These aspects have been approached before analytically, numerical. The current paper studies the influence of thelateral force on the contact patch of the wheel and the corresponding variations of vehicle stability parameters, such as camberangle and wheel rear track. The study is performed for a newer innovative rear suspensions mechanism which does not havea wheel track and camber angle variation, relative to the chassis, when the suspension components was considered rigid. Anumerical solution is obtained through a virtual model on several commercial codes: MSC Adams, Patran, Nastran. Concerning the analysed parametes, their variation increases as the applied force is increased. Moreover, the largest variationcorresponds to the case were elastic bushings and deformable links are considered.
