Suspension Arm Press Fitting via Anvil Support Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex shape of suspension arms in vehicle wheel suspension systems makes it difficult to press fit a shaft or pin into a tubular member without deforming the arm, and existing clamping methods are costly and inefficient.
Innovation Solution
A suspension arm design with an opening at the end allows access to the base end of the shaft, enabling support via an anvil during press fitting, reducing the force on the arm and eliminating the need for a complex clamping fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the suspension arm is firmly clamped to hold it stable during press fitting, then the stability of the suspension arm is improved, but the clamping force may deform the suspension arm
Solution Approach 1:
A support base with an anvil is introduced as an intermediary device between the press fitting force and the suspension arm. The anvil fits into the opening at the end of the suspension arm and provides localized support to the shaft base end, allowing the arm to be held stable without requiring excessive clamping force that would cause deformation
2Stability of the object's composition
If a complex clamping arrangement is designed to hold the suspension arm stable during press fitting, then the stability of the suspension arm is improved, but the device complexity increases
Solution Approach 1:
The suspension arm's own structure (the opening at its end) is utilized to facilitate its own stable positioning during press fitting. The opening accommodates the anvil of the support base, allowing the arm to be self-supported without requiring external complex clamping mechanisms
Solution Approach 2:
A simple support base with an anvil serves as an intermediary device that interfaces with the opening in the suspension arm. This simple intermediary provides stable support during press fitting without the need for complex clamping arrangements
3Stability of the object's composition
If a complex clamping arrangement is used to hold the suspension arm stable during press fitting, then the stability of the suspension arm is improved, but the productivity decreases
Solution Approach 1:
The suspension arm's opening structure enables it to be self-supported during press fitting through the anvil, eliminating the need for time-consuming setup and adjustment of complex clamping fixtures. This simplifies the assembling process and improves work efficiency
Solution Approach 2:
The support base with anvil acts as a simple intermediary device that quickly establishes stable support for the suspension arm during press fitting. The simplicity of this device reduces setup time and improves the overall productivity of the assembling process

AI summary
A suspension arm includes a shaft having a free end extending from an end of the suspension arm and a base end embedded within the said end of the suspension arm, and this shaft is configured to be press fitted into a tubular member of a compliance bush assembly. An opening is formed in the said end of the suspension arm that allows an anvil (41) to be inserted therein to engage the base end of the shaft so that the force of a press fitting process is prevented from affecting the remaining part of the suspension arm. Thus, the press fitting process can be facilitated because very little effort is required to place the suspension arm ready for a press fitting process, and the fixture for holding the suspension arm during a press fitting process can be simplified.
