Wheel Axle Lifting Arrangement With Disengaging Force Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lifting solutions for heavy-duty vehicle wheel axles are often large and heavy, which can lead to increased fuel consumption, tire wear, and reduced traction, and may damage sensitive mechanical elements when moving over bumps.
Innovation Solution
A lifting arrangement comprising elongated members with a vehicle frame coupling portion and a wheel axle coupling portion, offset from each other, that adjusts length between maximum and minimum positions using an engaging device, which can be disengaged to prevent force transfer and reduce the risk of damaging mechanical elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lifting solutions are used for heavy-duty vehicle wheel axles, then lifting capability is achieved, but the system becomes large and heavy, increasing fuel consumption and tire wear
Solution Approach 1:
The lifting arrangement uses a telescopic design with movable elongated members that can extend and retract dynamically. The engaging device allows the members to be locked in position during lifting operations and disengaged during normal vehicle operation, transforming a static heavy structure into a dynamic lightweight system that only adds weight when needed.
Solution Approach 2:
The lifting arrangement is divided into multiple separate elongated members (first elongated member, second elongated member) that can move independently relative to each other. This segmentation allows the system to achieve the required lifting capacity through coordinated movement of lighter individual components rather than a single heavy structure.
2Reliability
If traditional lifting solutions are used, then lifting capability is achieved, but mechanical elements are damaged when moving over bumps due to force transfer
Solution Approach 1:
The engaging device is designed to be disengaged during normal vehicle operation, extracting the lifting mechanism from the force transmission path. This allows road forces to bypass the sensitive mechanical elements of the lifting arrangement, preventing damage from bumps and irregularities while maintaining lifting capability when engaged.
Solution Approach 2:
The engaging device acts as an intermediary between the lifting mechanism and the wheel axle. When disengaged, it provides a mechanical disconnect that mediates the force transmission, allowing the lifting arrangement to remain intact while preventing harmful forces from reaching its sensitive components during normal vehicle operation.
3Length of moving object
If the engaging device is engaged to reduce length, then lifting capability is improved, but mechanical elements are exposed to damaging forces from wheel axle movements
Solution Approach 1:
The engaging device provides dynamic control over the mechanical connection between the lifting arrangement and the wheel axle. It can be engaged to reduce length for lifting operations and disengaged to protect mechanical elements, allowing the system to adapt its configuration based on operational requirements rather than being fixed in one state.
