Vehicle Cooling Module Stabilizer Pins and Bushings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle cooling system mounting methods using stay rods are time-consuming, labor-intensive, and occupy valuable space, while also transmitting stress and vibration to the cooling system.
Innovation Solution
The implementation of stabilizer pins and bushings that engage with stabilizer slots on the vehicle chassis, providing lateral support to prevent pivoting of the cooling system without transmitting vertical loads, thus replacing the need for stay rods and simplifying assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stay rods with multiple isolators and brackets are used to prevent pivoting, then the cooling system is stabilized, but assembly becomes time-consuming and labor-intensive
Solution Approach 1:
The stabilizer assembly is segmented into three main components: stabilizer pins attached to the cooling system, stabilizer bushings that interface with the pins, and stabilizer slots formed in the frame extender. This segmentation allows for simpler, faster assembly while maintaining the stabilizing function through the coordinated interaction of these discrete elements
Solution Approach 2:
The invention extracts the essential stabilizing function from the complex stay rod assembly and implements it through a simplified mechanism using pins, bushings, and slots. This extraction removes unnecessary brackets, isolators, and fasteners while preserving the core function of preventing pivoting motion
2Stability of the object's composition
If stay rods are used to prevent pivoting, then the cooling system is stabilized, but the complexity of the mounting system increases
Solution Approach 1:
The stabilizer assembly is segmented into three main components: stabilizer pins attached to the cooling system, stabilizer bushings that interface with the pins, and stabilizer slots formed in the frame extender. This segmentation allows for simpler, faster assembly while maintaining the stabilizing function through the coordinated interaction of these discrete elements
Solution Approach 2:
The invention extracts the essential stabilizing function from the complex stay rod assembly and implements it through a simplified mechanism using pins, bushings, and slots. This extraction removes unnecessary brackets, isolators, and fasteners while preserving the core function of preventing pivoting motion
3Object-affected harmful factors
If stay rods with multiple isolators are used, then vibration isolation is achieved, but the number of parts and assembly steps increases
Solution Approach 1:
The stabilizer bushings serve as intermediary elements between the stabilizer pins and the frame extender slots. These bushings provide vibration isolation and stress absorption while simplifying the overall assembly by eliminating the need for multiple separate isolators, brackets, and fasteners that were required in conventional stay rod arrangements
4Stability of the object's composition
If stabilizer components are added to prevent pivoting, then cooling system stability is improved, but underhood space is consumed
Solution Approach 1:
Instead of extending stabilizing elements outward from the cooling system (as with stay rods that protrude into the congested underhood space), the invention inverts the approach by forming stabilizer slots directly in the frame extender and using compact pins and bushings that interface between the cooling system and the frame structure. This reduces the space required for stabilizing components

This solution reduces installation time and labor, minimizes space usage, and effectively isolates the cooling system from stress and vibration, while maintaining stability and reducing the complexity and weight of the mounting system.
Implementation Method 1
The stabilizer pins and stabilizer bushings extend laterally into and engage with the stabilizer slots... effectively isolates the cooling system from stress and vibration

AI summary
A stabilizing arrangement of a cooling system module of a vehicle includes stabilizer pins attached to the vehicle cooling system module. Stabilizer slots are incorporated into a component of the chassis of the vehicle, such as a frame extender. The stabilizer slots may be formed as an upwards opening U-shape. Bushings are attached to the stabilizer pins. The stabilizer pins and bushings extend laterally into and engage with the stabilizer slots. Upon installation, the stabilizer pins and bushings are aligned with the stabilizer slots as the cooling system module is lowered onto the ISO mounts. The stabilizer pins and bushings slide vertically downwards into the stabilizer slots as the cooling system module is lowered into place. The simpler stabilizer pins, bushings, and stabilizer slots thereby take the place of expensive, time consuming, complex, labor intensive, and space consuming stay rod arrangements.
