Title (EN) POWER TRANSMISSION DEVICE
(FR) DISPOSITIF DE TRANSMISSION DE PUISSANCE
(JA) 動力伝達装置
Abstract:
(EN) A water pump (1) is equipped with: a pulley (4), provided with an internally toothed gear (4d) and an externally toothed gear (4e) provided radially inward from the internally toothed gear (4d); a shaft gear (5), with power being transmitted between this shaft gear and the pulley (4); and a transmission mechanism (6) that mediates the transmission of power between the pulley (4) and the shaft gear (5). The transmission mechanism (6) is equipped with: gears (6a, 6b) that set the transmission gear ratio to a first value when the internally toothed gear (4d) is engaged and sets the transmission gear ratio to a second value when the externally tooth gear (4e) is engaged; a rocker arm (6e) that, on the pulley (4) side, switches the gear engaged by the gears (6a, 6b) between the internally toothed gear (4d) and the externally toothed gear (4e); and a DC motor (6f) that drives the rocker arm (6e).
(FR) La présente invention se rapporte à une pompe à eau (1) qui est pourvue : d'une poulie (4), pourvue d'un engrenage à denture intérieure (4d) et d'un engrenage à denture extérieure (4e) agencé radialement vers l'intérieur depuis l'engrenage à denture intérieure (4d) ; d'un engrenage d'arbre (5), la puissance étant transmise entre cet engrenage d'arbre et la poulie (4) ; et d'un mécanisme de transmission (6) qui sert d'organe intermédiaire à la transmission de la puissance entre la poulie (4) et l'engrenage d'arbre (5). Le mécanisme de transmission (6) est pourvu : d'engrenages (6a, 6b) qui établissent le rapport d'engrenage de transmission à une première valeur lorsque l'engrenage à denture intérieure (4d) est engrené et établissent le rapport d'engrenage de transmission à une seconde valeur lorsque l'engrenage à denture extérieure (4e) est engrené ; d'un bras oscillant (6e) qui, côté poulie (4), commute l'engrenage engrené par les engrenages (6a, 6b) entre l'engrenage à denture intérieure (4d) et l'engrenage à denture extérieure (4e) ; et d'un moteur à courant continu (CC) (6f) qui entraîne le bras oscillant (6e).
(JA)  ウォータポンプ1は内歯ギヤ4dが設けられるとともに内歯ギヤ4dよりも径方向内側に外歯ギヤ4eが設けられているプーリ4と、プーリ4との間で動力の伝達が行われるシャフトギヤ5と、プーリ4およびシャフトギヤ5間で行われる動力の伝達を仲介する変速機構6とを備える。変速機構6は内歯ギヤ4dと係合する場合に変速比を第1の値にするとともに、外歯ギヤ4eと係合する場合に変速比を第2の値にするギヤ6a、6bと、プーリ4側におけるギヤ6a、6bの係合対象を内歯ギヤ4dと外歯ギヤ4eと間で切り替えるロッカーアーム6eと、ロッカーアーム6eを駆動するDCモータ6fとを備える。
