Title (DE) BRENNKRAFTMASCHINENVENTILTRIEBVORRICHTUNG
(EN) INTERNAL COMBUSTION ENGINE VALVE DRIVE DEVICE
(FR) DISPOSITIF DE DISTRIBUTION À SOUPAPES DE MOTEUR À COMBUSTION INTERNE
Abstract: front page image
(DE)Die Erfindung geht aus von einer Brennkraftmaschinenventiltriebvorrichtung mit zumindest einem Nockenelement (10a, 1 1a, 12a, 13a, 14a, 15a, 16a, 17a), das zumindest eine erste Nockenspur (18a, 19a, 20a, 21 a, 22a, 23a, 24a, 25a; 18b; 18c) aufweist, die zur Betätigung eines Ventils in zumindest zwei aufeinanderfolgenden Arbeitszyklen (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c) eines Zylinders (32a, 33a, 34a, 35a) vorgesehen ist und die zumindest zwei Arbeitsnocken (36a, 37a; 36b, 37b, 38b, 39b; 36c, 37c, 38c) umfasst, die jeweils dazu vorgesehen sind, das Ventil in einem der Arbeitszyklen (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c) zu betätigen. Es wird vorgeschlagen, dass das Nockenelement (10a, 1 1 a, 12a, 13a, 14a, 15a, 16a, 17a) zumindest eine zweite Nockenspur (40a, 41a, 42a, 43a, 44a, 45a, 46a, 47a; 40b; 40c) aufweist, die für eine Ventiltriebumschaltung vorgesehen ist.
(EN)The invention relates to an internal combustion engine valve drive device having at least one cam element (10a, 11a, 12a, 13a, 14a, 15a, 16a, 17a), the at least one cam element having at least one first cam track (18a, 19a, 20a, 21a, 22a, 23a, 24a, 25a; 18b; 18c) which is provided for actuating a valve in at least two successive working cycles (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c) of a cylinder (32a, 33a, 34a, 35a) and which comprises at least two working cams (36a, 37a; 36b, 37b, 38b, 39b; 36c, 37c, 38c) provided in each case for actuating the valve in one of the working cycles (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c). It is proposed that the cam element (10a, 11a, 12a, 13a, 14a, 15a, 16a, 17a) has at least one second cam track (40a, 41a, 42a, 43a, 44a, 45a, 46a, 47a; 40b; 40c) which is provided for a valve drive switchover.
(FR)L'invention concerne un dispositif de distribution à soupapes de moteur à combustion interne, doté d'au moins un élément à cames (10a, 11a, 12a, 13a, 14a, 15a, 16a, 17a), qui présente au moins une première trace (18a, 19a, 20a, 21a, 22a, 23a, 24a, 25a; 18b; 18c) pour cames prévue pour actionner une soupape dans au moins deux cycles de travail consécutifs (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c) d'un cylindre (32a, 33a, 34a, 35a) et qui comprend au moins deux cames de travail (36a, 37a; 36b, 37b, 38b, 39b; 36c, 37c, 38c) conçues chacune pour actionner la soupape dans un des cycles de travail (26a, 27a; 26b, 27b, 28b, 29b; 26c, 27c, 28c). Selon l'invention, l'élément à cames (10a, 11a, 12a, 13a, 14a, 15a, 16a, 17a) présente au moins une deuxième trace (40a, 41a, 42a, 43a, 44a, 45a, 46a, 47a; 40b; 40c) pour cames prévue pour une commutation de la distribution à soupapes.
