Hydraulic Track Width Adjustment With Integrated Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle track width adjustment systems are costly and lack efficient force transmission between the frame and running gear, limiting their effectiveness in varying terrain and attachment applications.
Innovation Solution
The use of hydraulic cylinders with components fixed to the frame and displaceable relative to it, designed to transmit forces transversely, replaces traditional support elements, allowing for adjustable track width and power transmission, with double-acting cylinders and guide elements ensuring stability and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional support elements are used for mounting chassis on the frame, then the structure is simple, but the force transmission between frame and running gear is inefficient and costly
Solution Approach 1:
The hydraulic cylinder's displaceable component is integrated with the support element, merging the force generation function with the force transmission function. The guide on the frame transmits forces transversely to the hydraulic cylinder axis, allowing the same component to perform both support and actuation functions, thereby improving force transmission efficiency without proportionally increasing device complexity
Solution Approach 2:
The displaceable component of the hydraulic cylinder serves multiple functions: it generates force for track width adjustment, transmits forces transversely through the guide, and maintains structural support. This multi-functionality replaces what would traditionally require separate support elements, improving overall system efficiency
2Adaptability or versatility
If hydraulic cylinders are used for track width adjustment, then the adjustability is improved, but the cost increases
Solution Approach 1:
By integrating the hydraulic cylinder with the support element and using the guide for transverse force transmission, the design eliminates the need for separate, expensive components. The merged structure reduces part count and manufacturing complexity while maintaining full track width adjustability
Solution Approach 2:
The hydraulic cylinder system performs multiple functions including adjustment and force transmission, reducing the need for additional specialized components. This multi-functionality lowers overall system cost while preserving adaptability
3Reliability
If separate support elements and hydraulic cylinders are used, then the functions are distinct, but the device complexity and cost increase
Solution Approach 1:
The support element and hydraulic cylinder are merged into a single integrated assembly where the displaceable component serves both support and actuation functions. The guide ensures proper force transmission, maintaining functional clarity while reducing component count and overall system complexity
