Patent Images
1. A wheel safety system for actuating the brake system on a vehicle in response to a wheel on the vehicle becoming disconnected, said wheel safety system comprising:
- (a) a wheel sensor located proximate the wheel on the vehicle, said wheel sensor being responsive to movement of the wheel and producing an output in response thereto;
(b) a brake controller coupled to the brake system of the vehicle and having an input for receiving the output from the wheel sensor, and an actuator for actuating the brake system in response to the output from said wheel sensor; and
(c) wherein said brake system provider means for arresting separation of the wheel from the vehicle.

Abstract
A wheel safety system for a vehicle. The wheel safety system includes wheel sensors and a brake control module. The wheel sensors are mounted on the vehicle proximate each of the wheels. The sensors detect if a wheel has become disconnected. The brake control module is coupled to the brake system for the vehicle and in response to a wheel sensor detecting a disconnected wheel, the control module actuates the brake system to arrest movement of the wheel.

4. A method for arresting the movement of a wheel which has become disconnected from the axle on a vehicle, said method comprising the steps of:
-
(a) monitoring the wheels on the vehicle; (b) detecting a fault condition wherein a wheel is disconnected from the axle; (c) in response to said fault condition, applying the brake system for the axle having the disconnected wheel; and (d) arresting separation of the disconnected wheel from the vehicle through application of the brake system. - View Dependent Claims (5)

6. A wheel safety system for actuating the brake system on a vehicle in response to a wheel on the vehicle becoming disconnected, the brake system including brake cylinders having spring brake chambers and service brake chambers in association with each of the wheels, a pressurized air source and air connect lines for pressurizing the brake cylinders and releasing the spring brake chambers, said wheel safety system comprising:
-
(a) wheel sensors for one or more of the wheels on the vehicle, each of said wheel sensors being coupled to said vehicle in a location proximate said associated wheel, and said wheel sensor being responsive to movement of said associated wheel and producing an output in response thereto; (b) a brake controller coupled to the brake system of the vehicle and having inputs for receiving the output from each of said wheel sensors, and an actuator for activating the brake cylinder for a wheel in response to an output from said wheel sensor for the wheel; and
(c) wherein said brake system provides means for arresting separation of the wheel from the vehicle. - View Dependent Claims (7, 8, 9, 10)
