Integrated Engine Support Bracket for Frame Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles face challenges in efficiently vibration-movable mounting of engines and transmissions due to space constraints and unfavorable load transfer, leading to suboptimal torsional rigidity and increased complexity in connection structures.
Innovation Solution
A support bracket that serves as both an engine/transmission mount and a cross member mount, featuring a receiving space for a bearing device and a connecting device to directly or indirectly attach to the vehicle frame, allowing for effective load absorption and transfer between longitudinal and cross members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate connection structures are used to connect the engine/transmission to the frame and to connect cross members to longitudinal members, then the mounting function is achieved, but the device complexity increases and installation space is consumed
Solution Approach 1:
The patent combines the engine/transmission mounting function and the cross member connection function into a single integrated support bracket. This bracket simultaneously connects to the longitudinal frame member and provides mounting points for both the engine/transmission and cross members, thereby reducing the number of separate connection structures and overall device complexity while maintaining all required mounting functions
Solution Approach 2:
The support bracket is designed as a multi-functional component that performs multiple roles: it serves as a mounting structure for the engine/transmission, as a connection point for cross members, and as a load transfer element between the frame and powertrain components. This universal design eliminates the need for separate specialized structures for each function
2Ease of operation
If spacing is provided between connection structures, then installation is facilitated, but load transfer becomes unfavorable and frame rigidity decreases
Solution Approach 1:
The support bracket extends in multiple spatial dimensions, with connection points arranged to optimize both installation accessibility and load transfer paths. The bracket's geometry is designed to provide adequate spacing for installation while maintaining short load paths to the frame structure, transferring forces efficiently in multiple directions simultaneously
3Productivity
If multiple separate parts are used, then assembly flexibility is improved, but assembly time increases and storage space is required
Solution Approach 1:
The patent integrates multiple previously separate components into a single support bracket assembly, reducing the total number of parts that need to be handled, stored, and assembled. This consolidation significantly reduces assembly time and storage requirements while the bracket's design maintains the necessary flexibility for proper installation and adjustment
