Technical Field
The present invention relates to amphibious vehicles and more particularly to a lightweight vessel of the trailer type for yachts and professionals.
Background
A tugboat is a boat particularly suited for sailing in the field of amphibious vehicles, this type of tugboat is typically a lightweight, navigable boat incorporating at least two wheels, and possibly a pulling system so that the boat can move on land.
Another known solution is a retractable wheel system U.S. patent No. 4515102 discloses a wheel system that can be switched between a rolling position and a sailing position, which can be simply held by the tension of a spring on the chassis against its stop.
For example, French patent No. 2773533A1 discloses a hull equipped with a rigid shaft that supports two suspension arms supporting the wheels.
In this latter case, a movable flap (gravette) attached to the hull allows the opening in the hull to close during the second phase to maintain the performance of the fairing during sailing.
In the particular case of amphibious vessels with semi-rigid hulls, the solution implemented by seales corporation consists of lifting the chassis at the bow and stern outside the semi-rigid hull.
The envisaged solution is complex to implement and presents a high risk of failure.
For an amphibious vessel with a semi-rigid hull from Sealegs, the chassis is visible in the retracted position. Thus, the contour of the boat is visually encumbered by the hull attachments constituted by the running gear, as compared to a conventional semi-rigid hull boat. The retracted running gear also significantly changes the center of gravity of the boat. The change in the center of gravity may affect the balance of the boat, making the boat less stable.
The objects of the invention are boats comprising a travel mechanism that simplifies the travel from a retracted position to a deployed position and vice versa.
In particular, objects of the invention are to propose amphibious craft with semi-rigid hull and visibly well integrated telescopic ride, with limited displacement of the centre of gravity of the craft.
Disclosure of Invention
An th aspect of the invention relates to an amphibious vehicle comprising at least preferably semi-rigid hulls having a length dimension, a width dimension and a depth dimension, and comprising at least running gear provided with at least wheels, said running gear being configured to be alternately in at least a retracted position and a deployed position in which at least wheels contact the ground.
Advantageously, the running gear comprises a fairing element integral with said running gear , wherein the fairing element is located below at least wheels in the depth dimension of the hull with the running gear in a retracted position, and wherein the hull comprises at least two inflation tubes on the perimeter of said hull, the running gear being located longitudinally between said two inflation tubes in the retracted position.
This arrangement substantially simplifies the change of the position of the running gear. By attaching the fairing elements to the running gear, the hull is closed and opened to allow the passage of multiple wheels to be automatic and synchronized. By reducing the number of parts required to arrange these two elements in motion, the risk of failure is also limited. For example, a separate system dedicated to opening and closing the hull is no longer required. Finally, the use is simplified by using a single control for the opening of the hull and the deployment of the running gear, as well as the retraction of the running gear and the closing of the hull.
The location of the running gear between the two inflation tubes allows the running gear to be directly integrated into the semi-rigid hull. The profile of the vessel of the conventional semi-rigid hull is thus preserved when the running gear is retracted. Furthermore, the vehicle in the retracted position requires less space than solutions comprising lifting the vehicle outside the semi-rigid hull.
Advantageously, the fairing element ensures a hydrodynamic continuity of the inflation tube on both sides of the chassis when the chassis is in the retracted position.
This arrangement of the running gear between the inflation tubes excludes this technical concept: i.e. such elements inserted between the gas tubes impair the sailing properties of the ship. In contrast, fairing elements attached to the running gear help stabilize the boat and limit the impact of the bow, especially during deceleration or curve travel.
Preferably, the running gear is located substantially at the centre of the length of the hull. Thus, by inserting the running gear in this position, the risk of shifting the centre of gravity towards the bow or stern of the ship is reduced.
The fairing elements are particularly effective for reasonably limiting splashing of material during rolling with the chassis deployed and advantageously complete the portion of the semi-rigid hull and/or smooth the exterior of the chassis in the retracted position so that the ship maintains its sailing performance.
According to possibilities, the fairing element is located at least partially in front of the position of the wheel tread and preferably in front of said wheel tread when pulled by a vehicle moving forward.
The fairing elements can include an inner surface configured to contain the splashes and discharge them downwardly to the ground.
Alternatively, the running gear may also comprise a second fender, which closes a second portion of the tread of the wheel opposite the th portion, to optimally contain any splashing of material during operation.
The inner surface of the fairing element can also be configured to at least partially house a running gear.
The outer surface of the fairing element can be convex.
The fairing elements can thus also form a fairing for the running gear in the deployed position, so that the flow of a fluid, such as air, is promoted.
Advantageously, the fairing elements can have a pneumatic effect in the deployed position and a hydrodynamic effect when retracted.
possibilities are that the hull of the ship is rigid.
Another possibilities are that the hull of the ship is semi-rigid and has at least two gas filled tubes on the perimeter of the hull.
