Title (EN) IN-WHEEL MOTOR SYSTEM
(FR) SYSTÈME DE MOTEUR-ROUE
(JA) インホイールモータシステム
Abstract:
(EN) A geared motor (10G) has an electric motor (10) and a reduction gear mechanism (11) for reducing the rotational speed of the electric motor (10) and transmitting the reduced speed to a wheel (2). The geared motor (10G) is elastically joined to a knuckle (5) by a dynamic vibration absorber (20) having a motor installation member (21) installed on the side face side of a motor case (10a), a knuckle installation member installed on the knuckle (5), a spring member (23) for connecting the motor installation member (21) and the knuckle installation member, two guide members (24, 24) for guiding the direction of operation of the spring member (23) into the vertical direction, and a damper placed in parallel with the guide members (24, 24). The motor (10) and the dynamic vibration absorber (20) are arranged behind the reduction gear mechanism (11). By the construction above, the motor (10) can have a sufficient stroke and the dynamic vibration absorber (20) can exhibit its performance sufficiently.
(FR) L'invention concerne un moteur (10G) à train d'engrenages comprenant un moteur électrique (10) et un mécanisme (11) à engrenages réducteurs permettant la réduction de la vitesse rotationnelle du moteur électrique (10) et la transmission de la vitesse réduite à une roue (2). Le moteur (10G) à engrenages est connecté de manière élastique à une articulation (5) par un amortisseur (20) de vibrations dynamique comprenant un élément (21) installé sur le côté de la face latérale du carter (10a) du moteur, un élément installé sur l'articulation (5), un élément (23) à ressort servant à connecter l'élément (21) installé sur le moteur et l'élément installé sur l'articulation, deux éléments (24, 24) de guidage destinés à guider le sens d'utilisation de l'élément (23) à ressort dans le sens vertical et un amortisseur positionné de manière parallèle aux éléments (24, 24) de guidage. Le moteur (10) et l'amortisseur (20) de vibrations dynamique sont positionnés derrière le mécanisme (11) à engrenages réducteurs. Grâce à cette construction, la course du moteur (10) et l'efficacité de l'amortisseur (20) de vibrations dynamique sont suffisantes.
(JA)  電気モータ10とこの電気モータ10の回転を減速してホイール2に伝達する減速歯車機構11とを備えたギヤドモータ10Gを、モータケース10aの側面側に取付けられるモータ取付部材21と、ナックル5に取付けられるナックル取付部材と、上記モータ取付部材21と上記ナックル取付部材とを連結するバネ部材23と上記バネ部材23の作動方向を上下方向に案内する2つのガイド部材24,24と、上記ガイド部材24,24に平行に配置されたダンパーとを備えた動的吸振装置20によりナックル5に弾性結合するとともに、上記電気モータ10と上記動的吸振装置20とを上記減速歯車機構11の後方に配置することにより、上記モータ10のストローク幅を十分に確保することができるようにするとともに、動的吸振装置20の性能を十分に発揮することのできるようにした。
