Innovation Solution
A steerable independent wheel suspension system with a support device that includes a guide column, wheel hub, and a support structure, allowing for adjustable height, damping, and spring mechanisms, which includes a mechanism to improve the support structure that includes a guide column, wheel hub, and a support structure, allowing for adjustable height, damping, and spring functions, with components connected via guide columns and support structures that can move relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rigid fixed suspension is used, then structural simplicity is maintained, but adaptability to different terrains and road conditions deteriorates
Solution Approach 1:
The patent applies dynamics by making the suspension system adjustable rather than fixed. The guide column can be positioned at different locations on the support structure, and the distance between the guide column and wheel hub can be varied, allowing the suspension characteristics to be dynamically adapted to different terrains and operational requirements.
Solution Approach 2:
The patent implements parameter changes by allowing variation in the distance between the guide column and wheel hub, as well as the position of the guide column on the support structure. These parameter changes enable the suspension system to be optimized for different conditions without requiring a completely different design.
2Adaptability or versatility
If adjustable suspension components are added, then adaptability to different terrains improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the guide column and support structure to serve multiple functions. The guide column provides both structural support and suspension guidance, while the support structure serves as both a mounting platform and a structural element that defines the suspension geometry. This multi-functionality reduces the need for separate dedicated components.
3Ease of operation
If the guide column is rigidly fixed, then structural stability is maintained, but maneuverability and adjustability deteriorate
Solution Approach 1:
The patent resolves this contradiction by making the guide column position adjustable rather than fixed. The guide column can be rigidly fixed at a chosen position to provide stability, or repositioned to different locations on the support structure to improve maneuverability and adaptability to different operational requirements.

AI summary
The invention relates, inter alia, to a steerable independent wheel suspension (12) for a mobile agricultural machine (10). A support device (18) serves to pivotally mount the independent wheel suspension (12) on a frame part (28) of the agricultural machine (10). At least one guide column (22) is slidably mounted in the support device (18). A wheel hub (24) is slidably guided along the at least one guide column (22). A support (74) is rigidly connected to the at least one guide column (22) for movement. The support (74) can enable a flexible and improved arrangement of height adjustment devices, damping devices, and suspension devices of the independent wheel suspension (12).
