Wheel Speed Sensor Mounting on Front Fork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In saddle-type vehicles, the exposure of the wheel speed sensor body to the outside, particularly when the brake caliper is supported on the rear side of the front fork, can compromise design aesthetics and complicate assembly and maintenance by creating disturbances between the sensor and brake caliper components.
Innovation Solution
A configuration where the wheel speed sensor body is supported in front of the front fork, and a downward extending portion of the front fender covers the sensor body, preventing exposure and interference with the brake caliper, while the sensor is mounted near the axle for improved assembly and maintenance ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor body is supported on the back side of the front fork to improve ease of assembly and maintenance, then ease of assembly and maintenance are improved, but the sensor body is exposed to the outside which disadvantages design aesthetics
Solution Approach 1:
The patent introduces a cover as an intermediary component that hides the sensor body from external view while allowing it to remain positioned on the back side of the front fork. The cover acts as a mediator between the sensor body and the external environment, preserving design aesthetics without compromising the ease of assembly and maintenance benefits
2Shape
If the sensor body is arranged to be covered by the front fender to suppress exposure, then design aesthetics are improved, but the ease of assembly and maintenance may be compromised
Solution Approach 1:
The patent segments the front fender into multiple portions, including a downward extending portion that specifically covers the sensor body. This segmentation allows the cover structure to be integrated into the existing fender design while maintaining access pathways for assembly and maintenance operations
3Temperature
If the brake caliper is supported on the rear side of the front fork to improve coolability, then cooling performance is improved, but the sensor body exposure compromises design aesthetics
Solution Approach 1:
The cover serves as an intermediary element that reconciles the conflicting requirements of brake caliper exposure for cooling and sensor body coverage for aesthetics. It allows the brake caliper to remain exposed on the rear side for thermal management while simultaneously hiding the sensor body to preserve design appearance

AI summary
A wheel speed sensor is provided between a front wheel and a front fork. The wheel speed sensor includes a sensor body to be supported by the front side of the front fork. A front fender includes a downward extending portion extending downward along the front side of the front fork. The downward extending portion covers the sensor body. As such, the influence of an arrangement of a sensor body on the design in a saddle-type vehicle provided with a wheel speed sensor between a front fork and a wheel is suppressed.
