Front Frame Suspension Structure With Integrated Brake Cooling Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing front frame assemblies of motor vehicles are bulky, heavy, and costly due to the need for separate ducts to cool the heat generated by the braking system, which restricts design freedom and increases weight and cost.
Innovation Solution
A front frame assembly that integrates a channel within the suspension attachment structure, allowing air to flow from the outside directly to the braking device through a vent and diffuser, eliminating the need for separate cooling ducts and optimizing air convection for effective heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate cooling ducts are used to cool the braking device, then the heat dissipation function is achieved, but the weight, cost, and device complexity increase
Solution Approach 1:
The patent merges the cooling duct function into the suspension attachment structure by forming the duct as an integrated cavity within the attachment structure body. This eliminates the need for separate cooling duct components, reducing device complexity while maintaining heat dissipation effectiveness through the unified structural design
2Temperature
If separate cooling ducts are used to cool the braking device, then the heat dissipation function is achieved, but the weight increases
Solution Approach 1:
The cooling duct is merged with the suspension attachment structure as an integrated component. The duct forms as a cavity within the attachment structure body, eliminating the need for separate duct materials and reducing overall weight while maintaining the heat dissipation function through the integrated design
3Temperature
If separate cooling ducts are used to cool the braking device, then the heat dissipation function is achieved, but the cost increases
Solution Approach 1:
The cooling duct function is merged into the suspension attachment structure, allowing both components to be manufactured as a single integrated part. This reduces manufacturing steps, eliminates assembly operations, and lowers production costs while maintaining effective heat dissipation through the unified structure
4Temperature
If separate cooling ducts are used to cool the braking device, then the heat dissipation function is achieved, but the design freedom is restricted
Solution Approach 1:
The cooling duct is merged with the suspension attachment structure, allowing the designer to optimize both cooling and suspension functions simultaneously within a single structural element. This integration enhances design freedom by enabling flexible configuration of the attachment structure to meet both thermal management and suspension requirements

AI summary
A front frame assembly for a motor vehicle includes a suspension attachment structure fixable to a body cell, one or more attachment elements fixed relative to the suspension attachment structure to allow a suspension of the motor vehicle to be coupled to the suspension attachment structure, and an absorption element to absorb a front crash of the motor vehicle, the absorption element being fixed relative to the suspension attachment structure and extending in a projecting manner relative to the suspension attachment structure along a first straight axis until ending with one end opposite the suspension attachment structure, wherein the assembly comprises a channel extending with continuity through the absorption element and the suspension attachment structure between an inlet opening obtained at the end along the first axis and an outlet opening obtained in the suspension attachment structure along a second axis transversal to the first axis.
