Abstract
(EN) The present utility model relates to an internal combustion engine having at least one driving unit (100) mounted inside a motor housing (M) and comprised of at least four pistons (200) grouped in pairs and interconnected by a connecting rod (250). Each connecting rod (250) has a pair of articulated arms (251) with two shorter arms (252), which are extendable (252-1), and two longer arms (253), the arms (252, 253) being connected to each other in an articulated manner and having, at their point of articulation, a bearing (254) which runs inside a track (255) in the motor housing (M). Each longer arm (253) has at the end thereof an actuator (256) pressed against the inner face of an oval of a flywheel (400) that has external toothing (410) and is supported by several pins with bearings (415) fastened internally on the motor housing (M).
(FR) Le présent modèle d'utilité concerne un moteur à combustion interne doté d'au moins une unité motrice (100) montée à l'intérieur d'un carter de moteur (M) et formée par au moins quatre pistons (200) regroupés en paires et reliés entre eux par une bielle (250). Chaque bielle (250) possède une paire de bras articulés (251) avec deux petits bras (252) extensibles (252-1) et deux grands bras (253), les bras (252, 253) étant reliés de manière articulée entre eux et dotés, au niveau de leur points d'articulation, d'un roulement (254) se déplaçant dans une piste (255) du carter du moteur (M). Chaque grand bras (253) possède en extrémité un actionneur (256) mis sous pression sur la face interne d'ovale d'un volant (400) denté extérieurement (410) et monté sur palier par l'intermédiaire de diverses tiges à roulements (415) fixés intérieurement dans le carter du moteur (M).
(PT) O presente modelo de utilidade se refere a um motor de combustão interna dotado de pelo menos uma unidade raoíriz (100) montada no interior de uma carcaça de motor (M) formada por peio menos quatro pistões (200) agrupados aos pares e ligados entre si por uma biela (250), Cada biela (250) possui um par de braços articulados (251) com dois braços menores (252) extensíveis (252-1 ) e dois braços maiores (253), sendo os braços (252, 253) interligados de modo articulado entre si e dotados, em seu ponto de articulação, de um rolamento (254) que corre dentro de uma pista (255) da carcaça do motor (M), Cada braço maior (263) possui em sua extremidade um aeionador (258) pressionado sobre a face interna de oval de um volante (400) dentado externamente (410) e mancatizado por vários pinos com rolamentos (415) fixos internamente na carcaça do motor (M).
