Abstract
A retrofit wheel speed sensing system for towed trailers including a retrofit tone ring retained at the inner grease seal location of a common in the art brake assembly and where said retrofit tone ring is monitored by a wheel speed sensor assembly mounted to said common in the art brake assembly where a wheel speed sensor is then connected to an Anti-lock Brake System (ABS) controller that modulates wheel speed during heavy braking. This invention thus retrofits existing common in the art trailer braking systems for ABS operation without replacing existing brake assemblies.
Claims16
An retrofit tone ring comprising;
- a tone ring body containing a plurality of exciting elements suitable to be detected with a sensor;
- said retrofit tone ring providing a means to be retained at the grease seal location of a idler hub;
- said exciting elements of said tone ring body rotate with said idler hub.
A sensor assembly comprising;
- a sensor capable of detecting passage of exciting elements of a retrofit tone ring;
- sensor mounting hardware;
- said sensor mounting hardware providing a means of retaining said sensor;
- said sensor mounting hardware providing a means of attachment to a brake assembly;
- said sensor monitoring the exciting elements of said retrofit tone ring installed at the grease seal location of a idler hub and thus said sensor monitoring the rotation of a retrofit tone ring.
