摘要:
Apparatus for transmitting the movement to a fan (1) for cooling the cooling fluid in a motor vehicle, comprising a driven shaft (2) on which the fan (1) is mounted idle by means of a support (1a) and a bearing (1b); means (11) for generating the movement, connected to the shaft (2) and coaxial and integral with the driving shaft of the vehicle; characterized in that it comprises a first free-wheel device (100) for transmitting the movement to the driven shaft (2) for operating the fan (1) with a first speed of rotation; a second device (200) for transmitting the movement to the driven shaft (2) for operating the fan (1) with a speed greater than that of the said free-wheel device (100); a control system (300) for engagement/disengagement of the second device (200) for selecting one or other of the two speeds; a clutch (400) with a double armature (431,432) which is arranged between the driven shaft (2) and the fan (1) and controlled engagement/disengagement of which is able to produce rotation of the fan (1) with one of the said different speeds or an idle condition of the fan (1) with respect to the driven shaft (2).
摘要:
The invention relates to a device for driving a turbo-machine, in particular a fan (2) of a motor vehicle, by means of an internal combustion engine, wherein the turbo-machine can be driven by the internal combustion engine by means of two drivetrains with in each case one control clutch and one shift clutch. It is proposed that the two drivetrains (14, 15) are arranged in parallel and that the turbo-machine (2) can be driven either by means of the shift clutch (12) or by means of the control clutch (8), wherein the two drivetrains preferably have unequal transmission ratios i1, i2 (i1 ≠ i2).

Device for transmission of the movement to a fan (1) for cooling the coolant in a motor vehicle, comprising means (21;141;31a) for supporting the fan (1) on which the fan (1) is mounted by means of an idle support (1a), means (3) for generating the movement, a first electromagnetic clutch (30), engagement of which produces rotation of the fan (1) at a number of revolutions equal to that of the movement generating means (3); also comprising means (50;150;250;350;450) for stopping rotation of the fan (1) in its idle condition.
摘要:
Un rotor de ventilateur (32) est entraîné par l'intermédiaire d'un accouplement à friction (34). Cet accouplement à friction (34) est un embrayage à disques. Un ressort (7) ferme l'accouplement à friction (34) par l'intermédiaire d'une bague de butée (5) non conductrice magnétiquement qui est fixée à une bague d'armature (16). Un électro-aimant (35) est fixé sur un carter moteur. Cet électro-aimant (35) peut ouvrir l'accouplement à friction (34) à l'encontre de la force du ressort (7). Un mécanisme de régulation (17) assure que l'accouplement à friction (34) s'ouvre progressivement ou par faibles paliers entre une température limite supérieure et une température limite inférieure.
摘要:
Es wird eine elektromagnetisch betätigbare Reibscheibenkupplung für ein Lüfterrad eines Ventilators, insbesondere von Kraftfahrzeug-Verbrennungsmotoren vorgeschlagen, bei welchen das Lüfterrad mit Motordrehzahl und zwei unterschiedlichen Schleppdrehzahlen antreibbar ist. Zur Herstellung der Motordrehzahl ist eine erste elektromagnetische Reibscheibenkupplung (4) vorgesehen, die das Lüfterrad (2) über einen Ankerring (15) und einer Lüfterradnabe (17) antreibt. Eine niedrigere Schleppdrehzahl wird durch eine zweite elektromagnetische Reibscheibenkupplung (6) über eine Wirbelstromkupplung (7) erzeugt. Hierzu dient ein spezielles, einstückiges Stufenkugellager (19), dessen Zwischenring (22) als Antriebsflansch (22) für die Wirbelstromkupplung (7) dient.
