L-Shaped Suspension Frame Reinforcement for Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension frame configurations, while improving rigidity by reinforcement, fail to adequately suppress deformation of both the front and rear walls under load, particularly at the boundaries between the center and arm portions.
Innovation Solution
A suspension frame structure featuring a reinforcement with an L-shape configuration, comprising a support portion connecting upper and lower walls, and outward-extending front and rear upright walls, which are joined to the upper and lower walls, enhancing rigidity and deformation suppression across multiple directions.

Engineering Contradiction Analysis
1Strength
If a reinforcement is arranged along a rear wall of the suspension frame, then the rigidity of the suspension frame is improved to some extent, but the deformation of the front wall cannot be sufficiently suppressed
Solution Approach 1:
The reinforcement is changed from a one-dimensional arrangement along the rear wall to a two-dimensional L-shaped structure that extends in both the front-rear direction and the vehicle-width direction. The L-shape includes a support portion connecting upper and lower walls, a front upright wall extending to the vehicle front side, and a rear upright wall extending to the vehicle rear side, creating coverage in multiple spatial dimensions to suppress deformation comprehensively
Solution Approach 2:
The reinforcement structure is strategically positioned with the support portion located inward in the vehicle-width direction of specific intersection points of extension lines of wall boundaries. This localized placement optimizes the distribution of reinforcement effects to where deformation is most likely to occur, while the L-shaped configuration provides both local and global structural support

AI summary
A suspension frame structure comprises a suspension frame and a reinforcement. The reinforcement has a support portion that extends in the up-down direction within the suspension frame and connects an upper wall and a lower wall of the suspension frame to each other, a front upright wall that extends outward in the vehicle-width direction and further to the front side of a vehicle from a side face of the support portion and is joined to at least one of the upper wall and the lower wall of the suspension frame, and a rear upright wall that extends outward in the vehicle-width direction and further to the rear side of the vehicle from the side face of the support portion and is joined to at least one of the upper wall and the lower wall of the suspension frame. The front upright wall and the rear upright wall form an L-shape.
