Work Vehicle Lateral Rod Support via Merged Bracket Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles with rigid axle suspensions face challenges in regulating lateral displacement of wheels without increasing the number of parts, leading to structural complexity and shock transmission to the driver during off-road use.
Innovation Solution
A work vehicle design that supports a lateral rod between projections on the body frame and axle cases, eliminating the need for brackets and using buffer members to absorb shocks and regulate lateral displacement, thereby maintaining wheel positioning and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are used to support the lateral rod, then the lateral rod can be supported, but the number of parts increases and structural complexity increases
Solution Approach 1:
The patent merges the lateral rod support function into the existing bracket structure used for mounting other components. The lateral rod is directly supported by the bracket that also serves as a mounting point for suspension components, eliminating the need for separate dedicated support brackets and reducing overall part count while maintaining structural integrity
Solution Approach 2:
The bracket structure is designed to serve multiple functions simultaneously: it mounts suspension components, provides structural support, and directly supports the lateral rod. This multi-functional design eliminates the need for separate dedicated support structures, reducing part count while ensuring reliable lateral rod support
2Reliability
If strong brackets are used to support the lateral rod, then the lateral rod can be supported, but the number of parts increases
Solution Approach 1:
The patent combines the lateral rod support function with existing structural brackets that are already part of the vehicle chassis. By integrating the lateral rod support into these multi-functional brackets, the design avoids adding separate dedicated support parts while ensuring adequate structural strength through the existing robust bracket design
3Ease of operation
If the wheels can move up and down greatly, then the suspension can absorb shock, but the wheels can reach their mechanical limits when lifted suddenly and greatly
Solution Approach 1:
The patent incorporates pre-configured mechanical stops and限位 structures within the suspension system that engage before the wheels can reach their extreme mechanical limits. These preliminary constraints are built into the suspension geometry and component positioning, preventing excessive wheel travel while maintaining adequate shock absorption capability through the coil springs and dampers
Solution Approach 2:
The suspension system includes pre-positioned mechanical限位 elements and buffer structures that engage when wheel travel approaches extreme positions. These beforehand cushioning features prevent sudden impacts at mechanical limits by providing gradual resistance as the wheel approaches its travel boundary, protecting against damage while allowing substantial shock absorption during normal operation

Function Achieved in This Case
This configuration effectively regulates lateral displacement of wheels without adding parts, reduces shock transmission, and prevents mechanical limits from being reached, enhancing the vehicle's stability and reducing structural complexity.
Implementation Method 1
a buffer member made of an elastic material or a rubber material... the buffer member comes into contact with the ground... prevents the wheel from disadvantageously reaching its mechanical limit

AI summary
A work vehicle according to the present invention includes left and right axle cases of a rigid axle type, and left and right suspension mechanisms movable in the up-down direction relative to body frames and separately supporting the left and right axle cases, respectively. The work vehicle also includes (i) a first projection projecting downward from the left or right one of the body frames, (ii) a second projection projecting upward from that position on either the left and right axle cases or a frame body integrated with the axle cases which is opposite to the first projection in the left-right direction, and (iii) a lateral rod having a first end connected with the first projection and a second end connected with the second projection.
