Steering Unit Housing with Integrated Stop for Over-Rotation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power steering unit installations are inefficient and prone to damage due to manual bearing installation, requiring additional materials and personnel, and separate installation of steering arms can lead to misplacement and damage.
Innovation Solution
A vehicular frame assembly with a housing and bearing system that allows for automated and precise installation of the steering unit, including a stop portion to prevent over-rotation, which integrates the steering arm and reduces the need for external bearings and separate installation steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual bearing installation is used in conventional power steering units, then the bearing can be installed, but the installation is inefficient and prone to damage requiring additional materials and personnel
Solution Approach 1:
The bearing is pre-installed into the housing during manufacturing, creating a pre-assembled unit that eliminates the need for field installation. This preliminary action ensures proper positioning and prevents damage that would occur during manual installation at the installation site.
Solution Approach 2:
The bearing installation process is merged with the housing manufacturing process. Instead of separate manual installation steps, the bearing is integrated into the housing during production, reducing the number of installation steps and personnel required.
2Ease of manufacture
If steering arms are installed separately in conventional power steering units, then the steering arm can be attached, but misplacement and damage occur due to separate installation steps
Solution Approach 1:
The steering arm attachment process is merged with the housing assembly process. The steering arm is attached to the housing during manufacturing rather than as a separate field installation step, ensuring proper placement and reducing the risk of misplacement or damage.
Solution Approach 2:
The steering arm is pre-attached to the housing during manufacturing, creating a pre-assembled unit. This preliminary action ensures correct positioning and eliminates the risk of improper installation that would occur during separate field installation.
3Reliability
If the stop portion is integrated into the housing, then over-rotation prevention is built-in, but the housing structure becomes more complex
Solution Approach 1:
The stop portion function is merged with the housing structure. Instead of being a separate component, the stop portion is integrated directly into the housing, providing over-rotation protection while minimizing additional structural complexity through functional integration.
Solution Approach 2:
The housing is given multiple functions: it provides structural support, houses the bearing, attaches the steering arm, and includes the stop portion for over-rotation protection. This multi-functionality reduces the need for separate components while maintaining reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates cost-effective and time-efficient installation of the steering unit with reduced risk of damage to components, enhancing the lifespan of the bearing and simplifying the installation process by integrating the steering arm and stop portion within the housing.
Implementation Method 1
The bearing is supported by the lower portion of the housing and is disposed at least partially within the interior of the housing. The steering shaft is journaled with respect to the lower portion of the housing by the bearing such that the steering shaft is rotatable with respect to the housing.

AI summary
A steering unit includes a housing, a steering shaft, a bearing, a steering arm, and a stop portion. The housing includes upper and lower portions that cooperate to define an interior. The steering shaft includes an upper and lower end. The bearing is supported by the lower portion of the housing and is disposed at least partially within the interior. The steering shaft is journaled with respect to the lower portion of the housing by the bearing. The steering arm is coupled with the lower end of the steering shaft and is configured for coupling to steerable wheels. The stop portion projects from the lower portion of the housing and into a travel path of the steering arm such that the steering arm selectively contacts the stop portion to prevent over-rotation of the steering shaft. A vehicular frame assembly for supporting the steering unit is also provided.
