Independent Drive Wheel Module With Rotating Camber-Caster Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The independently driving wheel module faces difficulties in adjusting dynamic geometry deviations during assembly to the vehicle body, limiting its flexibility and efficiency in vehicle motion and platform utilization.
Innovation Solution
The module incorporates a rotation plate with obliquely extending surfaces interposed between the base frame and vehicle body, allowing for adjustable camber and caster angles by rotating the plate, which is securely coupled via a coupling groove, enabling precise alignment and adjustment of the driving wheel's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the independently driving wheel module is assembled to the vehicle body without a rotation plate, then the assembly process is simpler, but it becomes difficult to adjust deviation for dynamic geometry during assembly
Solution Approach 1:
The rotation plate serves as an intermediary component between the base frame and the vehicle body, enabling adjustment of dynamic geometry deviations during assembly. The plate includes an upper surface and a lower surface extending obliquely in misaligned directions, allowing it to correct angular misalignments while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the rotation plate surfaces are extended obliquely in misaligned directions, then camber and caster angles can be adjusted, but the manufacturing complexity of the rotation plate increases
Solution Approach 1:
The rotation plate incorporates dynamic adjustability by extending its upper and lower surfaces obliquely in misaligned directions, allowing the camber and caster angles to be adjusted during assembly. This dynamic configuration enables the same component to adapt to different angular requirements without requiring multiple specialized parts.
3Ease of operation
If the rotation plate is securely coupled via coupling groove, then the rotation plate remains rotatable with respect to base frame or vehicle body, but the coupling mechanism becomes more complex
Solution Approach 1:
The coupling mechanism is segmented into distinct functional elements: the coupling groove formed in the base frame and the corresponding coupling protrusion on the rotation plate. This segmentation allows the rotation plate to be securely coupled while maintaining rotatability, as the groove-protrusion interface provides both guidance and rotational freedom without requiring complex additional mechanisms.

AI summary
An independently driving wheel module includes: a base frame including an upper end fixed to a coupling surface of a vehicle body, and a rotation part coupled to the upper end of the base frame such that the rotation part is rotatable with respect to the upper end of the base frame; a connection link including a first end integrally coupled to the rotation part, and a second end having a shape extending downward from the first end of the connection link; a driving wheel disposed at a side of the second end of the connection link and coupled to the second end of the connection link; and a rotation plate including an upper and lower surfaces extending obliquely in misaligned directions, the rotation plate being interposed between the base frame and the vehicle body so as to be rotatable with respect to the base frame or the vehicle body.
