Engine Mount Bracket Diagonal Support Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine mount supporting structures have insufficient upper part strength, leading to inadequate reduction of engine vibration and noise in vehicle passenger compartments.
Innovation Solution
An engine mount supporting structure with a front side frame, an upward convexly curved upper member, and a V-shaped attachment bracket that includes front and rear attached portions to the upper member, providing increased strength through diagonal support and a flange for enhanced rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the engine mount is coupled to the connecting plate at one point and to the side member at two points, then the lower part has required strength, but the upper part has insufficient strength to support the engine mount
Solution Approach 1:
The invention divides the upper support function into multiple segments by providing three separate coupling points (front upper, rear upper, and intermediate upper portions) on the connecting plate, rather than relying on a single coupling point. This segmentation distributes the load and increases overall upper part strength.
Solution Approach 2:
The invention merges the functions of multiple support points into a unified upper support system. By combining three coupling points on the connecting plate with the engine mount's upper coupled portion, the system achieves enhanced strength without proportionally increasing complexity.
2Strength
If the engine mount has a free upper portion, then the structure is simpler, but the strength to support the engine mount is insufficient
Solution Approach 1:
The invention transitions from a single-point or two-point support system to a three-dimensional distributed support system by positioning three coupling points at different locations (front, rear, and intermediate upper portions) on the connecting plate, creating a triangular support pattern that enhances strength.
Solution Approach 2:
The invention applies local quality by concentrating support functions at specific strategic locations on the connecting plate (front upper, rear upper, and intermediate upper portions) rather than distributing support uniformly or leaving the upper portion free. Each localized coupling point provides targeted strength where needed.

AI summary
An engine mount support structure provided in the front section of a vehicle body. A lower front support component and lower rear support component of the engine mount are installed to a frame-side front joining component and frame-side rear joining component, the frame-side front joining component and frame-side rear joining component being formed at the front and rear direction of the front side frame. An upper support component of the engine mount is supported by the upper member via a mounting bracket. The mounting bracket forms a V-shape and includes a front mounting component and rear mounting component respectively installed to a member-side front joining component and member-side rear joining component of the upper member; and an inner mounting component onto which the upper support component is installed.
