L'Invention est relative à un système de transmission dans lequel le vilebrequin (V) d'un moteur à combustion (M) est couplé par l'intermédiaire d'un dispositif de transmission par lien souple, notamment du type à courroie, à un arbre (1) d'un alterno-démarreur (ATD), caractérisé en ce qu'il présente un dispositif de couplage à deux états, à savoir un premier état correspondant à une phase de démarrage du moteur, dans lequel l'arbre (1) de l'alterno-démarreur (ATD) entraîne le vilebrequin (V) du moteur (M) dans un premier rapport de transmission, et un deuxième état dans lequel le vilebrequin (V) du moteur entraîne l'arbre (1) de l'alterno-démarreur (ATD) dans un deuxième rapport de transmission, et en ce que le premier rapport de transmission est supérieur au deuxième rapport de transmission.
Abstract:
A dual ratio belt drive system for powering rotating accessories. The system comprises a clutch unit rotatably connected to a rotating shaft and an overrunning clutch mounted directly to the rotating shaft. The system also comprises a plurality of rotating accessories rotatably connected to said clutch unit and rotatably connected to said rotating shaft through said over-running clutch such that said accessories are driven by said clutch unit at a first speed ratio and driven directly by said rotating shaft at a second speed ratio, with said clutch unit operating at a predetermined value of an engine operating condition thereby defining the transition between said first and second speed ratios, with said clutch unit being engaged at engine start.

본 발명은 자동차 얼터네이터용 오버러닝 풀리의 드라빙 동작시 뒤틀림 진동, 충격, 부하, 소음 등의 최소화에 보다 긍적적으로 작용할 수 있는 새로운 댐퍼수단에 관한 것이다. 즉, 자동차 내연 엔진의 동력을 인출하는 벨트(20)와, 그 벨트(20)에 의해 회전을 전달받는 풀리(30)와, 상기 풀리의 회전에 따라 중량의 로터(11)를 구동하는 로터 구동용 샤프트(12)와, 상기 풀리(30)와 로터 구동용 샤프트(12) 사이에 내장되면서 풀리(30)에 인가된 불규칙 동력 중 가속시에는 걸림에 의한 동력전달을 수행하는 반면 감속시에는 관성에 비례하는 공회전이 이루어지는 오버러닝 클러치(110)가 내장된 통상의 자동차용 얼터네이터(교류발전기)의 구동시스템(A)에 있어서, 상기 오버러닝 클러치(110) 자체의 내부에 일체형으로 내장·조립된 상태에서, 상기 풀리(30)에 인가된 불규칙 동력 및 관성으로 인해 나타나는 결함(뒤틀림 진동, 충격, 부하, 스트레스, 피로누적, 소음 등)에 대하여 보다 유연하면서 높은 탄성력으로 대처할 수 있고, 제조 및 조립성 또한 뛰어난 걸림링형 댐퍼장치(200)를 신규로 설치하여서 된 것이다.
Abstract:
A scooter which has a front wheel which is pivotal between a ground-engaging position and a storage position. The wheel is held at each position by means of a pin which engages with a respective notch in a component which pivots with the wheel. The pin is releasable, to allow the wheel to be pivoted, by simultaneously moving a brake pedal upwardly and an interlock member downwardly.
Abstract:
A key pulley segment in a synchronized, segmentally interchanging pulley transmission system is either first or last in a pulley segment set to engage an endless member. The first or last key segment teeth to engage or disengage, respectively, are shortened or completely trimmed, and the adjacent pulley segment to the key segment is elongated such that the inward portion of the tooth profile extends toward the key segment. Shortened tooth or teeth and an elongated adjacent segment together allow for many pulley segments to be designed as key segments. Completely trimmed teeth may be engineered to create a supporting surface for the endless member on the key segment. The elongated adjacent segment may have an extending portion which slidably mates with the supporting surface of the key segment, thereby receiving radial support therefrom. Multiple pulley segments from different pulley segment sets may be connected or constructed to move together in a unified stack, and may be staggered such that any one segment may be in an engaging position with the endless member when the unified stack is moved along the axis of rotation. Unified stacks may have guiding rails on both inner and outer radial surfaces, and the pulley assembly may have mating features that receive such guiding rails. Any number of the pulley segments in a unified stack may be key pulley segments. Pulley segments of a stack may be vertically separated into one or more unified stacks. Unified stacks may be moved by way of a cam or roller cam system, where each unified stack has a slidably or ratably attached roller and roller-arm. Chassis-mounted cams engage the rollers outside of the contact zone, rollers and roller-arms are moved into and out of engagement with the cams, and individual segments of a unified stack are moved into or out of engagement. Rollers may be actuated into and out of engagement by electromagnets, fixably mounted in an array. Rollers may discretely engage with multiple cams, by way of several electromagnet-arrays, and thereby complete several stack axial motions. Electromagnets in an array may be selectively energized to move selected rollers to an active position in order to effect key pulley segment engagement, stack axial movement and transition.
