Rear Wheel Roll Steering (Passive) Suspension Mechanism

This paper focuses on the concept and ideas for the development of Passive Four-Wheel Steering and will act as a foundation to build a robust and practical design. We always seek new methods to improve over existing ones, steering the rear wheels is always a fascination that an automotive engineer dreams of. The concept of treating angle as a vector quantity and further taking components of it and using them to generate Toe (steer) in the rear wheels through suspension linkages in accordance with the direction of cornering is analyzed in detail. Along with this a virtual design is incorporated and simulated to prove the practicality of the concept.
