Vehicle Suspension Lateral Oscillation Regulation via Rolling Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension systems for vehicles face challenges in effectively regulating lateral oscillations of the swing frame, leading to potential overload on the support shaft and reduced durability, particularly due to the use of lateral rods that connect the vehicle body and front axle case, which complicates load distribution and makes it difficult to prevent overload on the support shaft.
Innovation Solution
A suspension system design that includes a swing frame supported by a front frame with right and left suspension cylinders, and a lateral oscillation regulation unit between the swing frame and the front frame, utilizing a rolling body that contacts the side wall of the front frame to regulate lateral oscillations, thereby preventing overload on the support shaft without direct connection, and allowing for easy maintenance by replacing the contact plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lateral rod is used to regulate lateral oscillation of the swing frame, then the lateral oscillation can be regulated, but the support shaft becomes overloaded and durability reduces
Solution Approach 1:
The invention extracts the lateral oscillation regulation function from the connected lateral rod system and implements it through a laterally movable guide plate that can shift independently. This separates the oscillation regulation mechanism from the main support structure, preventing load transmission to the support shaft while maintaining oscillation control.
Solution Approach 2:
The guide plate acts as an intermediary element between the swing frame and the lateral rod. It provides a lateral movement interface that allows oscillation regulation without directly connecting the swing frame to the lateral rod, thereby mediating the load path and preventing overload on the support shaft.
2Reliability
If the swing frame is directly connected to the front frame, then structural stability is improved, but lateral oscillation regulation becomes difficult
Solution Approach 1:
The guide plate is designed to be laterally movable rather than fixed, allowing it to dynamically adjust its position to regulate oscillations. This dynamic capability enables oscillation control without requiring complex rigid connections between the swing frame and front frame.
Solution Approach 2:
The connection system is segmented into separate functional components: the guide plate for lateral movement, the lateral rod for oscillation regulation, and the support shaft for vertical loading. This segmentation allows each component to perform its specific function independently, simplifying the overall connection structure.

AI summary
A suspension system for a vehicle includes a swing frame and right and left suspension cylinders for front wheels. The swing frame is swingably supported by the front portion of a vehicle body about a support shaft extending in a lateral direction, and supports the front axle case, so as to allow the front axle case to swing about a center shaft extending in a front-rear direction. The right and left suspension cylinders are provided on the swing frame. A lateral oscillation regulation unit is provided between the swing frame and the front frame, and configured to regulate an oscillation of the swing frame by contact in the lateral direction.
