ACKERMANN STEERING Meaning and
Definition
-
Ackermann steering is a type of steering mechanism used in vehicles, particularly in automobiles, to improve the turning ability and maneuverability of the vehicle. It is named after its inventor, Georg Lankensperger Ackermann, a German carriage builder who patented the design in the early 19th century.
The principle behind Ackermann steering involves the use of interconnected steering arms and tie rods to control the movement of the front wheels. It is based on the concept that the steering angle for the inner wheel should be greater than that of the outer wheel when making a turn. This differential steering angle helps the wheels to follow different paths, resulting in a smoother and more coordinated turn.
The purpose of Ackermann steering is to reduce understeer, which occurs when the vehicle tends to move straight ahead instead of following the intended turn. By implementing the Ackermann principle, the vehicle's front wheels are able to turn at different angles, allowing for optimal wheel tracking and minimizing tire scrubbing. This leads to improved handling, stability, and reduced tire wear.
Ackermann steering is commonly used in most modern vehicles, especially those with front-wheel-drive or all-wheel-drive configurations. It is a fundamental component of the steering system, working in conjunction with other parts such as the steering rack, ball joints, and steering linkage.
In summary, Ackermann steering is a steering mechanism that allows the front wheels of a vehicle to turn at different angles when making a turn, ensuring better handling, stability, and reduced tire wear.
Etymology of ACKERMANN STEERING
The term "Ackermann steering" is named after a German carriage builder, Georg Lankensperger Ackermann. He developed a type of steering mechanism in the early 19th century that allowed vehicle wheels to follow different turning radii while maintaining a fixed steered wheel angle. This design significantly improved the vehicle's maneuverability and reduced tire wear. The mechanism gained popularity and became known as "Ackermann steering" in recognition of Ackermann's contribution to its development.
