Auxiliary Frame Mount Support Segmentation for Vibration Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary frames for vehicle front axles lack a straightforward method to achieve vibration stiffness for aggregate mounts, which is crucial for effective vibration damping and crash impact absorption.
Innovation Solution
The auxiliary frame design includes lateral longitudinal members, front and rear cross members, and a rear control arm console with console wings that have a mounting section for a separate guide sleeve mount support, allowing for a stiff connection between the frame and vehicle body, enhancing vibration damping and crash force absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large amount of material is used to construct mount supports on the auxiliary frame, then vibration stiffness is improved, but device complexity and material usage increase
Solution Approach 1:
The mount support is segmented into two distinct components: the console wing (integrated into the auxiliary frame) and the separate guide sleeve. This segmentation allows each component to be optimized independently - the console wing provides structural integration while the guide sleeve provides the vibration-stiff mounting surface, resolving the contradiction between simplicity and stiffness.
Solution Approach 2:
The mount support system combines different materials and structural forms - the console wing (likely metal or composite frame material) and the guide sleeve (separate mounting component). This composite approach enables achieving high vibration stiffness through the combination of components rather than requiring excessive material in a single monolithic structure.
2Reliability
If mount supports are constructed with large amounts of material to provide stiff connections, then vibration damping effectiveness is improved, but weight increases
Solution Approach 1:
By segmenting the mount support into the console wing and separate guide sleeve, the design achieves vibration damping effectiveness only where needed (at the mounting section) rather than distributing excessive material throughout the entire auxiliary frame structure, thus reducing overall weight while maintaining reliability.
Solution Approach 2:
The guide sleeve is positioned specifically at the mounting section where vibration stiffness is required for aggregate mount support. This local quality approach concentrates material and structural reinforcement only at the critical location rather than throughout the entire frame, achieving effective vibration damping with minimized weight.
3Ease of manufacture
If separate guide sleeve mount supports are used instead of integrated construction, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The separation into console wing and guide sleeve components enables each part to be manufactured using optimized processes suitable for its specific requirements, then assembled together. This segmentation improves ease of manufacture for each component while the standardized interface between them minimizes the complexity increase from having multiple parts.

AI summary
An auxiliary frame for a front axle of a two-track motor vehicle includes lateral longitudinal members extending in a longitudinal direction of the motor vehicle; front and rear cross members, said lateral longitudinal members converging at respective front and rear corner-joint parts with the front and rear cross members; at least one rear control arm console having console wings, with a rear wheel control arm of a wheel suspension of the motor vehicle being articulately connected between the console wings, one of the console wings having a mounting section; and at least one mount support for supporting an aggregate mount for a drive aggregate of the vehicle, wherein the mount support is formed on the mounting section of the one of the console wings.
