Kieferachse

The Kieferachse, or Kiefer axis, is a concept in German automotive engineering and design that refers to the alignment of the steering axis with the vehicle’s wheelbase. It is particularly relevant in the design of rear-wheel-drive and all-wheel-drive vehicles, where precise steering geometry plays a crucial role in handling and ride quality. The term originates from the German word "Kiefer," which translates to "steering," and "Achse," meaning "axis," highlighting its focus on steering alignment.

In practical terms, the Kieferachse describes the angle between the steering axis and the longitudinal axis of the vehicle. This alignment affects how the wheels respond to steering inputs, influencing factors such as cornering stability, road holding, and the vehicle’s overall feel. Properly adjusted, the Kieferachse helps maintain a balanced and predictable driving experience, especially at higher speeds or in tight turns. Conversely, incorrect alignment can lead to issues like uneven tire wear, poor handling, or a less responsive steering feel.

The concept is closely related to other steering geometry parameters, such as the toe-in or toe-out settings, which further define how the wheels are oriented relative to the vehicle’s centerline. While the Kieferachse itself is not a standalone adjustment, it is a foundational element in the design and tuning of steering systems, particularly in performance-oriented or specialized vehicles. Engineers and tuners often consider the Kieferachse alongside other factors to optimize a vehicle’s dynamic behavior for specific use cases, whether for daily driving, racing, or off-road conditions.
