Heavy Vehicle Chassis Component Bypassing Frame for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy vehicles face issues with rolling and vibrations during travel, which can lead to loss of vehicle control, component failure, and reduced driver comfort, with existing chassis designs failing to adequately address these problems.
Innovation Solution
A chassis component with a main and upper portion, featuring connection points for spring and/or damper arrangements that distribute load directly to the wheels, bypassing the frame structure, thereby reducing vibrations and rolling risks by providing a more direct path for forces to be absorbed by the wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load is transmitted through the frame structure, then structural integrity is maintained, but vibrations are amplified and rolling risk increases
Solution Approach 1:
The load transmission path is segmented into two separate paths: one through the frame structure for structural integrity, and another direct path through the suspension arrangement to the wheel for vibration reduction. This segmentation allows each path to handle specific types of forces optimally.
Solution Approach 2:
The suspension arrangement acts as an intermediary element that provides a dedicated load transmission path from the load carrying structure directly to the wheel, bypassing the frame structure for dynamic forces while maintaining structural connectivity.
2Strength
If spring and damper arrangements are connected to the frame structure, then structural support is provided, but vibrations are transmitted to the cab and components
Solution Approach 1:
The suspension arrangement serves as an intermediary that intercepts dynamic forces from the load carrying structure and directs them straight to the wheel assembly, preventing vibration transmission through the frame structure to the cab and other vehicle components.
Solution Approach 2:
The dynamic load transmission function is extracted from the frame structure and assigned to a dedicated suspension arrangement, allowing the frame to focus on structural support while the suspension handles vibration isolation.
3Ease of manufacture
If connection points are positioned at lower height, then manufacturing is simplified, but load distribution efficiency is reduced
Solution Approach 1:
The vertical position parameter of the connection points is optimized to a higher location on the load carrying structure, which improves the mechanical leverage and load distribution efficiency of the suspension arrangement, despite increased manufacturing complexity.
