Maneuverability is been one of the key things which people look for in their automobiles. This lead to the implementation of “Four wheel Steering “in vehicles. Four wheel steering is a system that allows the rear wheels to turn, rather than just following the front wheel. It is a system with two phases, a negative phase for slow speeds and a positive phase for the high speeds. Turning the rear wheels in the opposite direction to the front is the negative phases, which enhances faster maneuvering and a much tighter turning radius. Turning the rear wheels in the same direction as those at the front is the positive phase, which enhances sudden lane changes with much greater stability At present, there are three mechanisms used for steering the rear wheel. They are mechanical (using hypocycloidal gear set up), hydraulic and electrohydraulic. The reason for the system not being implemented in the commercial vehicle was its expensive nature. To overcome the above statement, a study was made on four wheel steering using tumbler gear mechanism. The result shows the decrease in the cost of implementation of the system and turning radius compared to two wheel steering respectively.
