Four wheel steering mechanism

1. 1. PRESENTATION ON FOUR WHEEL STEERING MECHANISM Submitted by: Ravinder kumar
2. 2. INRODUCTION Steering is the term applied to the collection of components, linkages, etc. which will allow a vessel (ship, boat) or vehicle (car, motorcycle, bicycle) to follow the desired course. An exception is the case of rail transport by which rail tracks combined together with railroad switches (and also known as 'points' in British English) provide the steering function.
3. 3. TYPES OF STEERING SYSYEM FRONT WHEEL STEERING. REAR WHEEL STEERING. FOUR WHEEL STEERING.
4. 4. BASIC GEOMETRY The basic aim of steering is to ensure that the wheels are pointing in the desired directions. This is typically achieved by a series of linkages, rods, pivots and gears.
5. 5. SKETCH OF FOUR WHEEL STEERING MODEL
6. 6. PRINCIPLE OF WORKING Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace outcircles of different radius.

8. 8. WORKING Four-wheel steering (or all-wheel steering) is a system employed by some vehicles to improve steering response, increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed.
9. 9. WAYS OF STEERING THE REAR WHEELS: a) Disconcordant steering (reverse phase); b) Conventional steering; c) Concordant steering (same phase)
10. 10. APPLICATION
11. 11. FEATURES & APPLICATIONS 1. This mechanism is in the racing vehicles where high vehicle stability is needed at high speeds while maneuvering. 2. Future vehicle 3. High Turning radius 4. More effective control 5. Automatic vehicle are equipped with this kind of system
