Work Vehicle Suspension Axle Bar Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension systems for work vehicles fail to effectively absorb energy from uneven terrain, leading to reduced traction and occupant comfort due to the transfer of forces from the rigidly connected axle housing to other vehicle components.
Innovation Solution
A suspension system comprising an axle bar, inner and outer control members, and a slide housing that pivots within an axle housing, coupled with a suspension cylinder that selectively extends and compresses to absorb energy, thereby increasing traction and comfort by isolating forces from the vehicle's frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the axle housing is rigidly connected to the frame, then structural strength and stability are improved, but forces from uneven terrain are transferred to other vehicle components, reducing traction and occupant comfort
Solution Approach 1:
The rigid axle housing connection is segmented into a movable suspension assembly that includes the axle housing, slide housing, and control members. This segmentation allows the axle housing to move independently relative to the frame through controlled pivoting and sliding motions, isolating force transfers while maintaining structural integrity.
Solution Approach 2:
The suspension cylinder and control members act as intermediary elements between the axle housing and the frame. These intermediaries absorb and dissipate forces through controlled motion, preventing direct force transfer to the frame and other vehicle components while maintaining structural support.
2Stability of the object's composition
If the axle housing is rigidly connected to the frame, then structural stability is improved, but occupant comfort in the cab is reduced due to force transfer
Solution Approach 1:
The connection between the axle housing and frame is segmented into independent movable components (slide housing, control members, suspension cylinder) that allow the axle housing to isolate vibrations and forces from the frame, thereby maintaining structural stability while improving occupant comfort.
Solution Approach 2:
The suspension cylinder and control members serve as intermediary elements that absorb and dampen forces between the axle housing and frame, preventing force transmission to the cab and improving occupant comfort while maintaining overall structural stability.
3Strength
If the axle housing is rigidly connected to the frame, then structural support is improved, but traction at the wheel is reduced due to force transfer
Solution Approach 1:
The rigid fixed connection is replaced with a dynamic suspension system that allows controlled motion between the axle housing and frame. The slide housing and control members enable the axle housing to move dynamically in response to terrain variations, maintaining wheel contact and traction while providing structural support.
Solution Approach 2:
The rigid connection is segmented into movable suspension components that allow the axle housing to independently respond to terrain forces, maintaining optimal wheel contact for traction while preserving overall structural support through the suspension mechanism.

AI summary
A suspension system for a work vehicle includes an axle bar, an inner control member, an outer control member, and a slide housing. The axle bar extends through the inner control member, the outer control member, and the slide housing. The axle bar is non-rotatably coupled to the slide housing and is configured to pivot with the slide housing and relative to the inner control member and the outer control member.
