Open-Profile Chassis Component for Protected Bearing Sensor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chassis components, particularly those made of sheet metal, often lack the capability to accommodate a blind hole-like recess for sensor device attachment, limiting the options for securely integrating sensor devices.
Innovation Solution
A chassis component design featuring a one-piece profile that is open on one side, allowing for the integration of a sensor device with a sensor housing that can be fastened using independent fastening means, providing protection and proximity to the bearing, and utilizing a multi-stepped contour for a flat and functional design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blind hole-like recess is used for sensor device attachment, then the sensor device can be securely integrated, but this option is not available for chassis components made of sheet metal
Solution Approach 1:
The sensor housing is divided into multiple sections with different functions: a first section that receives the sensor element and is arranged inside the profile, and a second section that extends outside the profile for mounting purposes. This segmentation allows the sensor device to be securely integrated while adapting to sheet metal chassis components that cannot accommodate blind hole-like recesses.
Solution Approach 2:
The sensor housing transitions from a purely internal arrangement to a multi-dimensional configuration that extends both inside and outside the profile. This dimensional change enables the sensor device to be securely integrated within the profile structure while providing external mounting surfaces for attachment to sheet metal chassis components.
2Measurement precision
If the sensor element is positioned close to the bearing for precise measurement, then measurement precision improves, but the sensor element becomes more exposed to external influences
Solution Approach 1:
The first section of the sensor housing is arranged inside the interior of the profile, creating a nested configuration where the sensor element is protected within the profile structure. This nesting allows the sensor element to be positioned close to the bearing for precise measurement while the profile structure shields it from external influences such as dust, moisture, and mechanical damage.
Solution Approach 2:
The sensor housing acts as a protective shell that encloses the sensor element. This shell structure provides physical protection while allowing the sensor element to maintain its optimal position near the bearing for accurate detection of relative rotation.
3Object-affected harmful factors
If the sensor housing is completely enclosed for protection, then protection from external influences improves, but accessibility for mounting and maintenance deteriorates
Solution Approach 1:
The sensor housing is segmented into a first section arranged inside the profile for protection and a second section extending outside the profile for mounting. This segmentation provides both protection from external influences and accessibility for mounting and maintenance operations.
Solution Approach 2:
The second section of the sensor housing serves multiple functions: it provides a mounting interface for attaching the sensor device to the chassis component, extends the protective enclosure, and maintains accessibility for installation and maintenance. This multi-functionality resolves the contradiction between protection and accessibility.

AI summary
The invention relates to a chassis component (1, 32) comprising a first end section (2) and a second end section (3), wherein a connection section (4) is arranged between the two end sections (2, 3), comprising at least one bearing (9, 10) in one of the two end sections (2, 3), and comprising a sensor device (13), wherein a sensor housing (14, 33) has a first sensor element (16) of the sensor device (13). In order to improve and/or allow for an arrangement of the sensor device (13) and/or the sensor housing (14) on the chassis component (1, 32), the chassis component (1, 32) is characterised in that the two end sections (2, 3) and the connection section (4) are designed as a single-part and as a profile (5) that is open on one side along the longitudinal extension, wherein the open profile (5) forms an at least partially free internal space (17), and in that the first sensor element (16) is arranged within the internal space (17).
