Description

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se refiere a una tabla de surf motorizada que presenta una configuración que reduce al máximo su altura de carena y baja su centro de gravedad. The present invention relates to a motorized surfboard that has a configuration that minimizes its hull height and lowers its center of gravity.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

Se conocen tablas de surf motorizadas que comprenden una carena en cuyo interior se encuentra dispuesto un motor de explosión acoplado mediante una transmisión a un impulsor (hélice o turbina) en contacto con el agua. Motorized surfboards are known which comprise a mask inside which an explosion engine is arranged coupled by means of a transmission to an impeller (propeller or turbine) in contact with the water.

Dado el espacio que ocupa el motor de explosión, con su cilindro y cárter, se obliga a la carena a adoptar una altura capaz de alojar estos elementos (más otros como el motor de arranque, depósito de combustible, carburador o inyector etc) que eleva su perfil y su centro de gravedad respecto a las tablas de surf exentas de motorización, modificando su comportamiento y aumentando las sensaciones de inestabilidad. Given the space occupied by the explosion engine, with its cylinder and crankcase, the cowl is forced to adopt a height capable of accommodating these elements (plus others such as the starter, fuel tank, carburetor or injector etc) that elevates its profile and its center of gravity with respect to surfboards exempt from motorization, modifying their behavior and increasing feelings of instability.

Para intentar solucionar estos problemas, se conoce una realización de tabla motorizada donde el motor va dispuesto longitudinalmente (el cigüeñal es paralelo o está alineado con la dirección longitudinal de la tabla), con el cigüeñal precisamente alineado con el plano de crujía de la misma de forma que hay un acoplamiento directo entre dicho cigüeñal y el eje del impulsor. Tiene el inconveniente de que el cilindro está desplazado hacia un lateral de la carena, y dado que el cilindro siempre va a ocupar un volumen equivalente a su diámetro más sus paredes y la refrigeración, no consigue una gran reducción de altura teniendo en cuenta que el perfil de la carena es mayor en el centro y disminuye hacia los lados. Además, el colector de escape de gases requiere un exclusivo y costoso diseño para no aumentar en exceso la altura y poder caber en la zona lateral de la carena. To try to solve these problems, an embodiment of a motorized board is known where the engine is arranged longitudinally (the crankshaft is parallel or aligned with the longitudinal direction of the board), with the crankshaft precisely aligned with the crunch plane thereof such that there is a direct coupling between said crankshaft and the impeller shaft. It has the disadvantage that the cylinder is displaced to one side of the cowl, and since the cylinder will always occupy a volume equivalent to its diameter plus its walls and cooling, it does not achieve a large reduction in height taking into account that the Profile of the fairing is greater in the center and decreases sideways. In addition, the exhaust manifold requires an exclusive and expensive design so as not to excessively increase the height and be able to fit in the side area of the cowl.

Otra realización conocida comprende disponer el motor transversalmente a la dirección longitudinal de la tabla. Esta realización minimiza el problema de la altura interior de la carena, pero requieren de complicadas transmisiones para acoplamiento al eje del impulsor, con transmisiones cónicas y similares que producen elevadas pérdidas. Teniendo en cuenta que la potencia de un motor de tabla de surf es pequeña, estas pérdidas bajan el rendimiento y elevan el consumo de combustible. Además aumentan el coste y peso de la tabla, y requieren frecuentes trabajos de mantenimiento para engrase de dichas transmisiones. Another known embodiment comprises arranging the motor transversely to the longitudinal direction of the table. This embodiment minimizes the problem of the inner height of the fairing, but requires complicated transmissions for coupling to the impeller shaft, with conical and similar transmissions that produce high losses. Taking into account that the power of a surfboard engine is small, these losses lower performance and increase fuel consumption. They also increase the cost and weight of the board, and require frequent maintenance work to grease these transmissions.

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

La tabla de surf motorizada de la invención es del tipo que comprenden una carena en cuyo interior se encuentra dispuesto un motor de explosión, acoplado mediante una transmisión a un impulsor (hélice o turbina) en contacto con el agua. The motorized surfboard of the invention is of the type comprising a mask inside of which an explosion engine is arranged, coupled by means of a transmission to an impeller (propeller or turbine) in contact with the water.

De acuerdo con la invención, el motor se encuentra dispuesto en posición longitudinal de forma que el cilindro se encuentra ubicado en la zona central y de mayor altura de la carena con una salida de escape directa, esto es, que accede directamente al exterior a través de las paredes del cilindro y por tanto también por la zona central de la carena, para que el colector de escape discurra inicialmente por dicha zona central y de mayor altura interior. De esta forma el sobreancho que el colector superpone a la anchura del propio cilindro se ubica en la zona de la carena que ya de por sí debe tener mayor altura por cuestiones de hidrodinámica de la tabla, reduciendo al máximo la altura libre necesaria y bajando el centro de gravedad. According to the invention, the engine is arranged in a longitudinal position so that the cylinder is located in the central area and of greater height of the cowl with a direct exhaust outlet, that is, that accesses directly to the outside through of the cylinder walls and therefore also through the central area of the cowl, so that the exhaust manifold initially runs through said central area and of greater interior height. In this way, the width that the collector superimposes on the width of the cylinder itself is located in the area of the cowl that already must have a greater height due to hydrodynamics of the table, reducing the necessary free height to the maximum and lowering the gravity center.

Además, la transmisión comprende un primer eje de transmisión primaria de salida del motor, (entendiendo como tal que está acoplada al cigüeñal y/o tiene la misma dirección de giro) y un segundo eje de transmisión secundaria de accionamiento del impulsor, siendo el primer eje paralelo al segundo eje. Esto permite el acoplamiento entre ambos ejes a través de engranajes, cadenas y/o correas de reducido diámetro sin obligar a elevar la altura de la carena en los laterales, y que además requieren un bajo mantenimiento. In addition, the transmission comprises a first primary transmission shaft of the motor output, (understood as such that it is coupled to the crankshaft and / or has the same direction of rotation) and a second secondary transmission shaft of impeller drive, the first being axis parallel to the second axis. This allows the coupling between both axes through gears, chains and / or belts of small diameter without forcing the height of the hull to be raised on the sides, and which also require low maintenance.
