Abstract
Un engranaje de válvula variable de un motor de combustión interna para un vehículo del tipo de montar a horcajadas en el que: una cámara de válvula (67) está formada entre una culata de cilindro (27) y una cubierta de culata (28) unida una a otra constituyendo al mismo tiempo una parte de un cuerpo de motor (14) montado en un bastidor de carrocería de vehículo (F); brazos basculantes primero y segundo (71, 72) dispuestos adyacentes uno a otro dentro de la cámara de válvula (67), estando al menos uno de ellos enclavado y unido a una válvula de motor (61), están articulados de forma basculante a la culata de cilindro (27) a través de un eje basculante (78) de manera que puedan bascular en modos de basculamientos diferentes uno de otro cuando los brazos basculantes (71, 72) estén en un estado no unido; un pasador de unión (97) que tiene un eje central paralelo al eje basculante (78) está encajado deslizantemente en los brazos basculantes primero y segundo (71, 72) de manera que se pueda mover entre una posición de unión para cabalgar entre los brazos basculantes primero y segundo (71, 72) y unir ambos brazos basculantes (71, 72) uno a otro y una posición de liberación de unión para separarse del segundo brazo basculante (72) y liberar la unión de ambos brazos basculantes (71, 72); y un vástago de presión (104) al que se le imparte una fuerza de presión desde un solenoide (107) montado en el cuerpo de motor (14) se hace apoyar sobre un extremo del pasador de unión (97) en el lado opuesto del segundo brazo basculante (72), donde el solenoide (107) está montado solamente en una pared lateral de la cubierta de culata (27) en el mismo lado de una bujía de encendido (65) que está montada en una pared lateral de la culata de cilindro (27) por una pluralidad de elementos de fijación (110) de modo que se evite que un alojamiento (108) del solenoide (107) y la extensión del eje central (CP) de la bujía de encendido (65) se solapen uno con otro, caracterizado porque el solenoide (107) y la bujía de encendido (65) están dispuestos en un lado que mira a un lado, en la dirección a lo ancho del vehículo, del cuerpo de motor (14) que está articulado de forma basculante al bastidor de carrocería de vehículo (F); y el alojamiento (108) del solenoide (107) está dispuesto más alto que el eje central (CP) de la bujía de encendido (65) en vista lateral.A variable valve gear of an internal combustion engine for a straddle type vehicle in which: a valve chamber (67) is formed between a cylinder head (27) and a cylinder head cover (28) attached one at the same time constituting a part of a motor body (14) mounted on a vehicle body frame (F); first and second swing arms (71, 72) arranged adjacent to each other inside the valve chamber (67), at least one of them being locked and attached to a motor valve (61), are pivotally articulated to the cylinder head (27) through a tilting axis (78) so that they can swing in different ways of tilting each other when the tilting arms (71, 72) are in an unbound state; a connecting pin (97) having a central axis parallel to the tilting axis (78) is slidably engaged in the first and second tilting arms (71, 72) so that it can move between a joining position to ride between the arms first and second swingarms (71, 72) and join both swingarms (71, 72) to each other and a joint release position to separate from the second swingarm (72) and release the joint of both swingarms (71, 72 ); and a pressure rod (104) to which a pressure force is imparted from a solenoid (107) mounted on the motor body (14) is supported on one end of the connecting pin (97) on the opposite side of the second rocker arm (72), where the solenoid (107) is mounted only on a side wall of the cylinder head cover (27) on the same side of a spark plug (65) that is mounted on a side wall of the cylinder head of cylinder (27) by a plurality of fasteners (110) so that a housing (108) of the solenoid (107) and the central shaft extension (CP) of the spark plug (65) are prevented from overlapping with each other, characterized in that the solenoid (107) and the spark plug (65) are arranged on one side facing the vehicle body side (14) that is articulated in a direction that is wide of the vehicle tilting shape to the vehicle body frame (F); and the housing (108) of the solenoid (107) is arranged higher than the central shaft (CP) of the spark plug (65) in side view.
