Four wheel steering is a relatively new technology, that imposes maneuverability in cars, trucks and trailers .in standard two wheels steering vehicles, the rear set of wheels are always directed forward therefore and do not play an active role in controlling the steering in four wheel steering system the rear wheel can turn left and right . To keep the driving controls as simple as possible.
Advantages of four wheel steering system
Superior cornering stability:- The vehicle cornering behaviour become more stable and controllable at high speed as well as on wet slipping road surfaces.Improved steering response and precision:- The vehicle response to steering input becomes quicker and more precise through out the vehicle enter speed range.High speed straight line stability:- the vehicle’s straight –line stability at high speed is improved. Negative effects of road irregularities and crosswinds on the vehicles stability are minimised.Improved rapid lane-changing maneuvers: - This is stability in lane changing at high speed is improved. In high speed type operation become easier. The vehicle is less likely to go into a spin even in situations in which the driver must make a sudden and relatively large change of direction.Smaller turning radius:- By steering the rear wheels in the duration opposite the front wheels at low speed,the vehicle’s turning circle is greatly reduced.
Disadvantage of four wheel drive
The 4-WS construction of many components, the system becomes more expensive.The system includes as many components (especially electronically) there is always a change to get any of the part inactive, thus the system become inoperative2.
advantages of two wheel drive
The advantage would be that both wheels could contribute to acceleration without breaking traction.
However, I think the mechanical challenges of this are considerable and not worth solving to gain that small advantage.
