Abstract

An apparatus, system and method have a sensor positioned above a rear axle attached to a brake of a trailer. The sensor detects whether the temperature of the brake exceeds a threshold temperature. A light is mounted on the trailer and activates in response to the temperature of the brake exceeding the threshold temperature. A handle is pulled to distribute a fluid on the rear axle of the trailer. A conduit extends across the underside of the trailer wherein the conduit carries the fluid. A nozzle sprays the fluid over the rear axle.

Claims

1. An apparatus mounted on a trailer for extinguishing fire at a wheels and axles assembly of the trailer, apparatus comprising:

a discharge nozzle mounted on the trailer and configured to spray a fluid at the axles;

a temperature sensor positioned above and in between two set of wheels and axles assembly supporting the trailer, wherein the temperature sensor is configured to detect a temperature of a brake on the axles;

at least two warning lights mounted on a same side wall of the trailer, in a line of sight of a driver sitting in a truck cab pulling the trailer, and the at least two warning lights being positioned to be visible from a vehicle attached to and pulling the trailer, wherein the at least two warning lights are configured to activate in response to the temperature of the brake exceeding a threshold temperature;

a first activating handle mounted on a front portion of the side wall of the trailer, the handle configured to be pulled, wherein pull the activating handle causes the fluid to be supplied to the discharge nozzle; and

a wireless temperature monitor configured to compare the detected temperature of the brake with the threshold temperature and activate the warning light when the detected temperature at the brake exceeds the threshold temperature, indicating a potential fire condition at the wheels and axles assembly.

2. The apparatus of claim 1, further comprising a bottle attached to the trailer and hold the fluid.

3. The apparatus of claim 1, further comprising a conduit configured to carry the fluid to the discharge nozzle.

4. The apparatus of claim 1, wherein the wireless temperature monitor is configured to compare the detected temperature with the threshold temperature to determine whether the detected temperature exceeds the threshold temperature, and notify a driver via activation of the warning light.

5. The apparatus of claim 1, wherein the at least two warning lights are positioned on the trailer so as to be viewable by a driver.

6. The apparatus of claim 2, wherein the bottle and the discharge nozzle are configured to be positioned beneath the trailer.

7. The apparatus of claim 1, wherein the discharge nozzle is configured to spray the fluid over a distribution area proportionately sized to encompass a fire over the axles.

8. The apparatus of claim 2, further comprising:

a second bottle attached to a different side wall of the trailer and holding additional fluid; and

a second handle mounted adjacent the first activating handle on the trailer and operable to be pulled, wherein pulling the second handle causes the fluid to be supplied from the second bottle to the discharge nozzle.

9. The apparatus of claim 2, wherein the bottle contains a fire retardant fluid.

10. The apparatus of claim 1, wherein the temperature sensor is further configured to detect a temperature of a wheel bearing or tire of the wheels and axle assembly.
