Axle Support Mounts With Indentations For Steering Gear Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subframe arrangements for motor vehicle steering gears require significant effort for positioning and securing, often necessitating additional tools like adjusting pins, and offer limited precision in alignment.
Innovation Solution
An axle support with longitudinal members and a cross member, featuring mounts with indentations for direct positioning of steering gear housing positioning protrusions, eliminating the need for auxiliary tools and allowing precise alignment in multiple directions without additional components or tools, using sheet metal or tubular structures with V-shaped or arc-shaped indentations for improved tolerance management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adjusting pins are used for positioning the steering gear, then positioning precision is improved, but device complexity and manufacturing effort increase
Solution Approach 1:
The patent extracts the positioning function from separate auxiliary tools (adjusting pins) and integrates it directly into the axle support structure through mounts with indentations. This eliminates the need for separate positioning devices while maintaining positioning precision, thereby reducing device complexity without sacrificing manufacturing precision.
Solution Approach 2:
The patent combines the positioning function with the mounting structure by integrating mounts that have both attachment and positioning capabilities. The mounts with indentations serve dual purposes: securing the steering gear and providing precise positioning, thereby merging two functions into one component and reducing overall device complexity.
2Manufacturing precision
If adjusting pins are used for positioning the steering gear, then positioning precision is improved, but assembly time and productivity decrease
Solution Approach 1:
The patent incorporates positioning indentations directly into the mounts that are already part of the axle support structure. This preliminary integration of positioning features into the mounting components eliminates the need for separate positioning steps and auxiliary tools during assembly, thereby maintaining positioning precision while significantly reducing assembly time and improving productivity.
3Manufacturing precision
If multiple auxiliary tools are used for positioning, then positioning accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent designs the mounts with integrated positioning indentations that automatically guide and position the steering gear housing during assembly. The structure itself provides the positioning function without requiring external auxiliary tools or complex adjustment procedures, thereby maintaining positioning accuracy while significantly improving ease of operation.

AI summary
The invention relates to an axle support, also referred to as a subframe, for a motor vehicle, having at least two longitudinal members, at least one cross member joining together the longitudinal members, at least two attachment points for attaching a steering gear housing to the axle support and a device for positioning the steering gear housing on the axle support prior to mounting of the steering gear housing on the axle support. In order for such an axle support to offer a cost-effective and rapid positioning of a steering gear housing, the device for positioning the steering gear housing according to the invention has at least two mounts, one mount of which being attached to one of the longitudinal members and/or the cross member and another mount of the mounts being attached to another of the longitudinal members and/or the cross member, wherein the respective mount has at least two indentations for receiving positioning protrusions provided on the steering gear housing.
