Center Bearing Bracket Assembly NVH Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional center bearing bracket assemblies have poor noise, vibration, and harshness (NVH) characteristics, are difficult to manufacture and install, and have limited durability, often causing fouling between components.
Innovation Solution
A center bearing bracket assembly comprising one or more center bearing brackets, plates, and attachment members, where the plates and attachment members are integrally formed or connected to the vehicle's frame, providing improved structural support and reducing NVH through specific design features such as apertures and extending portions for enhanced mounting and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional center bearing bracket assemblies are used, then the structure is simple, but the noise, vibration, and harshness (NVH) characteristics are poor
Solution Approach 1:
The patent combines multiple components (center bearing bracket, plates, attachment members) into an integrated assembly where the plates are connected to both the center bearing bracket and the vehicle frame, creating a unified structure that improves NVH characteristics through enhanced structural coherence and reduced vibrations
Solution Approach 2:
The assembly uses composite construction with different materials for different components (metal brackets, plates, and attachment members), where each material is selected for its specific properties to optimize vibration damping and noise reduction while maintaining structural integrity
2Ease of manufacture
If conventional center bearing bracket assemblies are used, then the design is simple, but they are difficult to manufacture and install
Solution Approach 1:
The assembly is segmented into distinct but connected components (center bearing bracket, plates, attachment members), allowing each component to be manufactured separately using optimal processes and then assembled together, improving both manufacturability and installation ease while maintaining a relatively simple overall design
3Reliability
If conventional center bearing bracket assemblies are used, then the structure is simple, but they have poor overall life and durability
Solution Approach 1:
The integrated connection system where plates are simultaneously connected to the center bearing bracket and vehicle frame creates a more robust and durable assembly that distributes mechanical stresses across multiple connection points, enhancing overall reliability and service life
Solution Approach 2:
The design applies local reinforcement through strategically positioned plates and attachment members at critical stress points and connection areas, providing enhanced durability where needed while maintaining a relatively simple overall structure
4Object-generated harmful factors
If conventional center bearing bracket assemblies are used, then the design is simple, but they cause fouling between the center bearing cushion and mating components
Solution Approach 1:
The design extracts and isolates the center bearing cushion from direct contact with mating components by introducing intermediate plates and attachment members, preventing fouling and contamination while maintaining a relatively simple overall assembly design
