Abstract

The present invention relates to an amphibious vehicle comprising a vehicle frame and a cab supported by said vehicle frame, said cab being connected to said vehicle frame via hinge means so as to allow tilting of said cab about said hinge means between a closed position and an open position, wherein said vehicle comprises a sealing arrangement comprising sealing means arranged to provide liquid tight sealing between the cab and the vehicle frame in said closed position, wherein in the closed position, the sealing arrangement is arranged to provide a confined space for protecting components of said vehicle enclosed inside said space.

First claim

The invention claimed is:

1. An amphibious vehicle comprising a vehicle frame and a cab supported by said vehicle frame, characterized in that said cab being connected to said vehicle frame via a hinge so as to allow tilting of said cab about said hinge between a closed position and an open position, wherein said vehicle comprises a sealing arrangement comprising a seal arranged to provide liquid tight sealing between the cab and the vehicle frame in said closed position, wherein in the closed position, the sealing arrangement is arranged to provide a confined space for protecting components of said vehicle enclosed inside said space, wherein the seal comprises an electrically conductive electromagnetic sealing element with an electrically conductive surface that makes an electrical contact with a second electrically conductive surface when the vehicle frame and the cab are in the closed position such that a Faraday cage is formed by the vehicle frame and the cab through the electrical contact in the closed position so as to control an emitted electromagnetic signature within said confined space.

2. The amphibious vehicle according to claim 1 , wherein a said cab and said vehicle frame comprises a contact surface, and wherein the contact surface of said cab is arranged to face the contact surface of said vehicle frame in the closed position.

3. The amphibious vehicle according to a claim 2 , wherein said seal comprises at least one sealing element extending along the contact surface of said cab and/or the contact surface of said vehicle frame, said surface defining a sealing plane for providing said sealing in the closed position.

4. The amphibious vehicle according to claim 3 , wherein the seal for providing liquid tight sealing in the closed position comprises a first sealing element of the seal arranged in connection to the contact surface of the cab.

5. The amphibious vehicle according to claim 4 , wherein the seal for providing liquid tight sealing in the closed position comprises a second sealing element of the seal arranged in connection to the contact surface of the vehicle frame.

6. The amphibious vehicle according to claim 5 , wherein said first sealing element and/or said second sealing element are inflatable.

7. The amphibious vehicle according to claim 2 , wherein the contact surface of said cab and/or the contact surface of said vehicle frame has a frame configuration.

8. The amphibious vehicle according to claim 2 , wherein the contact surface of said cab and said vehicle frame has a planar configuration.

9. The amphibious vehicle according to claim 5 , further comprising a control unit for controlling the pressure of the inflatable sealing element.

10. The amphibious vehicle according to claim 1 , further comprising an engine for driving the vehicle, where the engine is housed in the vehicle frame in the confined space.

11. The amphibious vehicle according to claim 3 , wherein the at least one sealing element extending along the contact surface of said cab is arranged recessed into a recess on the underside of the cab so that a portion of the cab overhangs the sealing plane when the cab is in the closed position.

12. The amphibious vehicle according to claim 1 wherein said vehicle is a tracked vehicle.
