Abstract

A mine protection device for a wheeled vehicle having a plurality of wheels, wherein each wheel is connected to the vehicle by a wheel suspension, and the device includes: at least one sensor associated with each wheel, wherein each sensor operates to detect when the associated wheel has driven over a mine or when a proximate mine is ignited; at least one ignition and analysis unit connected to receive sensor signals from each sensor, wherein the at least one ignition and analysis unit processes individual sensor signals; and a separation means associated with each wheel, wherein the separation means operates to separate the associated wheel from the vehicle, when the associated wheel has driven over a mine or when a proximate mine has been ignited, by separating the wheel suspension connected to the associated wheel from the vehicle.

Claims

1. A mine protection device for a wheeled vehicle having a plurality of wheels, wherein each wheel is connected to the vehicle by a wheel building block, the device comprising:

at least one sensor associated with a wheel, wherein the sensor operates to detect when a mine has been ignited;

at least one ignition and analysis unit connected to receive sensor signals from the sensor, wherein the at least one ignition and analysis unit processes individual sensor signals; and

a separation means, associated with the wheel, for separating the associated wheel from the vehicle when the mine has been ignited by separating the wheel building block connected to the associated wheel from the vehicle.

2. A mine protection device according to claim 1, wherein the wheel building block is a wheel suspension.

3. A mine protection device according to claim 1, wherein the separation means comprises a wedge charge.

4. A mine protection device according to claim 1, wherein the separation means comprises at least one pyrotechnic separation screw.

5. A mine protection device according to claim 1, wherein the sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

6. A mine protection device according to claim 2, wherein the sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

7. A mine protection device according to claim 3, wherein the sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

8. A mine protection device according to claim 4, wherein the sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

9. A vehicle comprising:

(a) a vehicle frame;

(b) a plurality of wheels rotatingly connected to the vehicle frame, wherein each wheel is connected to the frame by a wheel suspension; and

(c) a mine protection device associated with the vehicle frame, the device comprising;

(i) a sensor associated with at least one wheel, wherein the sensor is arranged to detect a proximate exploding mine;

(ii) an ignition and analysis unit operably connected to receive signal input from the sensor, wherein the ignition and analysis unit processes sensor signal input and generates an activation signal output in response thereto, and

(iii) a separation means associated with the at least one wheel, wherein the separation means is connected to receive activation signal input from the ignition and analysis unit.

10. A vehicle as recited in claim 9, wherein when the at least one wheel of the plurality of wheels drives over and detonates a mine, the sensor associated with the one wheel detects the exploding mine and generates sensor signal input, the ignition and analysis unit receives and processes the sensor signal input then sends an activation signal to the separation means associated with the one wheel, and in response to receiving the activation signal, the separation means separates the one wheel from the vehicle by separating the wheel suspension connected to the one wheel from the vehicle frame.

11. A vehicle as recited in claim 10, wherein the separation means comprises a wedge charge.

12. A vehicle as recited in claim 10, wherein the separation means comprises at least one pyrotechnic separation screw.

13. A vehicle as recited in claim 9, wherein the sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

14. A vehicle as recited in claim 11, wherein each sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

15. A vehicle as recited in claim 12, wherein each sensor is selected from the group consisting of an optical sensor, a pressure sensor and an acceleration sensor.

16. A vehicle comprising:

(a) a structural unit separable from a remainder of the vehicle;

(b) an explosion protection device associated with the structural unit, the device comprising;

(i) a sensor disposed on the vehicle so as to detect a light flash or a blast wave of an exploding device;

(ii) a ignition and analysis unit connected to receive a sensor signal from the sensor; and

(iii) separation means connected to receive an activation signal from the ignition and analysis unit.

17. A vehicle as recited in claim 16, wherein the sensor operates to send the sensor signal to the ignition and analysis unit when the sensor detects the light flash or the blast wave of the exploding device, the ignition and analysis unit operates to send the activation signal to the separation means upon receiving the sensor signal, and the separation means operates to separate the structural unit from the remainder of the vehicle in response to receiving the activation signal.

18. A method for protecting a vehicle from an exploding device, comprising the steps of:

(a) providing a vehicle having a separable structural unit, and an explosion protection device associated with the structural unit, the mine protection device comprising;

(i) a sensor;

(ii) an ignition and analysis unit operably connected to receive a sensor signal from the sensor; and

(iii) a separation means for separating the structural unit from the remainder of the vehicle, wherein the separation means is operably connected to receive an activation signal from the ignition and analysis unit;

(b) when the sensor detects a light flash or blast wave from the exploding device, generating a sensor signal using the sensor;

(c) using the ignition and analysis unit to receive the sensor signal, and in response thereto, generating an activation signal; and

(d) activating the separation means using the activation signal so the separation means separates the structural unit from the remainder of the vehicle.
