Detachable Impulse Ring for Cost-Effective Rail Axle Speed Sensing

The pulse ring is separated from the end cap and manufactured as an independent component. This segmentation allows the pulse ring to be produced using cost-effective methods such as laser cutting, punching, or forming from strip material, while the end cap can be manufactured separately. The two components are then joined through attachment mechanisms such as pressing, screwing, welding, or gluing, thereby reducing overall manufacturing cost while maintaining structural integrity through proper connection design.

The pulse ring is designed as a separate, interchangeable component that can be attached to different end cap types. This allows the pulse ring to be customized with specific profile patterns and gearing configurations for different applications, while the basic end cap structure can remain standardized. Multiple pulse rings with different profile patterns can be manufactured using the same cost-effective processes and swapped between end caps as needed, thereby maintaining adaptability while reducing manufacturing costs through standardization of the end cap production.

Instead of using expensive precision-machined metal gears, the pulse ring can be manufactured using cost-effective methods such as laser cutting, punching, or forming from strip material. The profile pattern is created through these alternative processes rather than traditional mechanical machining. This substitution maintains the functional precision needed for sensor cooperation while dramatically reducing manufacturing costs through the use of more economical production methods.
