Steering Linkage Alignment Member for Ball Joint Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle steering linkages face challenges in maintaining precise alignment and adjustment of ball joints during assembly, leading to potential misalignment and increased risk of ball stud breakage due to jounce and rebound movements.
Innovation Solution
The improved steering linkage employs an alignment member with complimentary shaped openings and a turnbuckle-style adjuster mechanism that ensures the drag link assemblies' ball joints are oriented and adjusted in a predetermined configuration, maintaining alignment even during length adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drag link assemblies are used without alignment members, then the assembly process is simpler, but the ball joints become misaligned and prone to breakage during jounce and rebound movements
Solution Approach 1:
An alignment member (third member) is introduced as an intermediary component between the first and second drag link assemblies. This alignment member includes openings that receive and align the ball joints, ensuring proper orientation and preventing misalignment during vehicle operation. The alignment member acts as a mediator that maintains the predetermined parallel orientation between the two drag link assemblies, thereby improving reliability without significantly complicating the overall structure.
2Ease of operation
If the ball joints are allowed to move freely during adjustment, then the adjuster mechanism is easier to operate, but the ball joints become misaligned and may break due to jounce and rebound
Solution Approach 1:
The alignment member is pre-configured with openings positioned and oriented to receive the ball joints in their correct aligned positions. Before the adjuster mechanism is operated to adjust the length of the drag link assemblies, the alignment member is already in place to guide and maintain proper ball joint orientation. This preliminary positioning ensures that even as the adjuster mechanism operates freely, the ball joints remain aligned and protected from misalignment-induced breakage during jounce and rebound movements.
