Adjustable Governor Lever Linkage Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal combustion engines face challenges in the reliable and efficient assembly of governor levers and linkage assemblies, leading to potential assembly errors and increased time required for assembly.
Innovation Solution
The proposed solution involves a governor lever with a primary arm, a secondary arm, and a fastener, which allows for adjustable coupling to a governor shaft. This configuration enables the governor lever to move between two positions, ensuring proper alignment and minimizing slack or tension in the linkage assembly.

Engineering Contradiction Analysis
1Productivity
If traditional governor linkage assembly is used, then the governor mechanism can operate, but assembly time increases and assembly errors occur
Solution Approach 1:
The governor linkage assembly is divided into distinct modular components: governor lever, primary arm, secondary arm, and fastener. Each component can be assembled and adjusted independently, allowing for easier assembly and reducing the time required while minimizing assembly errors through standardized interfaces.
Solution Approach 2:
The governor lever is designed with movable coupling between the primary arm and secondary arm, allowing dynamic adjustment of the linkage geometry. This dynamic capability enables proper alignment during assembly and operation, reducing assembly time and improving reliability by accommodating manufacturing tolerances.
2Manufacturing precision
If governor lever is made movable between positions, then proper alignment is achieved, but device complexity increases
Solution Approach 1:
The governor lever incorporates movable coupling between the primary arm and secondary arm, allowing the linkage to dynamically adjust its geometry. This enables precise alignment during assembly and operation without requiring complex fixed adjustment mechanisms, achieving high manufacturing precision through controlled mobility.
Solution Approach 2:
The linkage assembly allows for parameter changes in the relative positions and orientations of the primary and secondary arms. By enabling the governor lever to move between different positions, the system can optimize alignment accuracy for various operating conditions without significantly increasing structural complexity.

AI summary
An engine having a linkage assembly, the linkage assembly having a governor lever, a governor shaft, and a throttle link. The governor lever couples the governor shaft to the throttle link. The governor lever is configured to adjust the relative position between the throttle link and the governor shaft. The governor lever has a primary arm and a secondary arm, the primary arm being movable with respect to the secondary arm. The primary arm and secondary arm are secured via a fastener which prevents relative motion between the primary and secondary arms.
