FOUR MODE STEERING SYSTEM FOR A FOUR WHEEL

MECHANICAL ENGINEERING

The most conventional and general steering arrangement is to turn the front wheels using a hand–operated steering wheel which is positioned in front of the driver. The four wheel four mode steering system is a modification for the present steering which is used for the improvement of easiness for vehicle handling. The four wheel four mode steering system assists driver by controlling the steering angle of vehicle’s four wheels as the requirement of driver, for making the parking and handling at congested areas easier. For meeting the application the rear wheels steer in the opposite direction or in the same direction of the front wheels, allowing reduced turning radius or sliding of vehicle to sideways; also steering each wheel in opposite direction to rotate the vehicle about its position. We are able to transmit the motion that is given on steering wheel to the rear wheels and able to control like front wheels as our requirements, which is the basic idea of our project four wheel four mode. In convertible four wheel steering with four mode operation four steering modes can be changed as needed which assists in parking at heavy traffic conditions, when negotiating areas where short turning radius is needed, when rotation of the vehicle about its position (360 degree rotation) and in off road Driving.
