Sensor Bearing Assembly With Spacer-Mounted Angular Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor bearing assemblies for vehicles require specific shapes on the fork and axle to secure the sensor device, which complicates installation and may lead to damage during mounting.
Innovation Solution
A sensor bearing assembly design featuring a bearing with an inner and outer ring, an impulse ring secured to the outer ring, and a sensor device with a spacer that allows for simplified mounting without additional shapes on the vehicle, using a spacer with an inner diameter matching the inner ring and an impulse ring with openings for tool access, ensuring the assembly's radial dimensions align with the bearing, eliminating the need for specific axle and hub shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor device is freely mounted onto the spacer without fixed securing, then the sensor device can be easily installed, but the sensor device cannot maintain precise angular positioning
Solution Approach 1:
The sensor device is fixedly secured onto the spacer by merging the mounting operations, eliminating the need for separate securing steps while maintaining precise angular positioning through the integrated fixed connection
2Reliability
If the sensor bearing assembly requires specific shapes on the fork and axle to secure the sensor device, then the sensor device can be securely mounted, but the device complexity and installation difficulty increase
Solution Approach 1:
The spacer serves multiple functions: it positions the sensor device axially, maintains radial alignment with the bearing, and provides a mounting surface, eliminating the need for specific vehicle fork or axle shapes and reducing overall system complexity
3Strength
If the impulse ring is secured directly without openings, then the structural integrity is maintained, but tool access for installation is blocked causing damage
Solution Approach 1:
The impulse ring is segmented with openings that allow tool access for installation while maintaining structural integrity through strategic placement and sizing of the openings that do not compromise the overall strength
4Ease of operation
If the spacer protrudes radially inwards relative to the inner ring or the impulse ring protrudes radially outwards relative to the outer ring, then the sensor device can be mounted, but the radial boundary dimensions increase requiring specific vehicle shapes
Solution Approach 1:
The sensor device and spacer are nested within the radial boundaries of the bearing, with the spacer's inner diameter matching the inner ring's inner diameter and the impulse ring's outer diameter not exceeding the outer ring's outer diameter, eliminating the need for specific vehicle fork or axle shapes

AI summary
A sensor bearing assembly includes a bearing having an inner ring and an outer ring centered on an axis, an impulse ring secured to the outer ring of the bearing, and a sensor device for detecting rotational parameters of the impulse ring. The sensor device includes a sensor housing and at least one sensor element supported by the sensor housing and cooperating with the impulse ring. Also an annular spacer adapted to axially abut against a lateral face of the inner ring of the bearing. The sensor housing is fixedly secured to the spacer, the inner diameter of the spacer is equal to the inner diameter of the inner ring of the bearing, and the outer diameter of the impulse ring is less than or equal to the outer diameter of the outer ring of the bearing.
