Vehicle Compressor Mounting With Shared Axle Retaining Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting air-conditioner compressors on vehicle bodies are inefficient, requiring large installation space and weight due to bulky assembly supports, and often necessitate alternative connections for non-driven axles, leading to increased costs and complexity.
Innovation Solution
The solution involves using additional bearing elements and a retaining unit mounted on the vehicle body, with decoupling elements between the drive assembly and bearing elements, allowing for improved rigidity and reduced weight, enabling universal use across varying vehicle embodiments and simplifying installation by attaching the compressor to the same axle regardless of drive status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assembly supports are used to mount the air-conditioner compressor on the vehicle body, then the compressor can be securely mounted, but the installation space required increases and the weight increases
Solution Approach 1:
The mounting system is divided into separate functional elements: bearing elements mounted directly to the vehicle body, and a retaining unit that connects to these bearing elements. This segmentation allows the compressor to be mounted without requiring large, bulky assembly supports, as each component performs a specific function with optimized space requirements.
Solution Approach 2:
The mounting system utilizes the spatial dimension more efficiently by distributing bearing elements at different locations on the vehicle body and using a retaining unit that spans between them. This dimensional approach allows secure mounting with reduced overall footprint compared to traditional single-block assembly supports.
2Reliability
If assembly supports are used to mount the air-conditioner compressor on the vehicle body, then the compressor can be securely mounted, but the weight increases
Solution Approach 1:
By segmenting the mounting system into separate bearing elements and a retaining unit, each component can be optimized for minimal weight while maintaining its specific function. This eliminates the need for heavy, monolithic assembly supports that traditionally required excessive material to achieve the same mounting security.
Solution Approach 2:
The retaining unit serves multiple functions simultaneously: it connects the compressor to the bearing elements, provides structural support, and enables acoustic vibration decoupling. This merging of functions into a single component reduces the total weight compared to using separate components for each function.
3Area of stationary object
If the air-conditioner compressor is mounted on a nondriven axle, then space is optimized, but alternative connection methods are required for vehicles with different drive configurations
Solution Approach 1:
The mounting device is designed as a universal system that can be installed on any axle type (driven or nondriven) of the vehicle. The bearing elements and retaining unit are configured to work with standard vehicle body mounting points, allowing the same device to be used across different vehicle configurations without requiring alternative connection methods.
4Object-affected harmful factors
If decoupling elements are arranged between the drive assembly and the bearing elements, then vibration decoupling is improved, but the device complexity increases
Solution Approach 1:
Decoupling elements are introduced as intermediary components between the drive assembly and the bearing elements. These intermediaries provide acoustic vibration decoupling while maintaining the structural connection, effectively reducing harmful vibrations without significantly complicating the overall mounting device.
