要約
(EN)
[PROBLEMS] An electrically-driven wheel-driving device where durability of rolling bearings is increased, that is reduced in size and in weight, and that improves traveling performance of a vehicle. [MEANS FOR SOLVING PROBLEMS] An electric wheel-driving device has a bearing device (2) for a wheel, a planetary speed reducer (3), a driving section (6), and a rotation-transmitting device (5) for connecting a rotating shaft (4) and an input shaft (21) installed coaxial with the rotating shaft (4) via serrations (27b). The planetary speed reducer (3) has a sun roller (17), planetary rollers (15) rolling along the inner peripheral surface of an external member (9), and carrier pins (14) for rotatably supporting the planetary rollers (15) at a hub wheel (7). The rotation-transmitting device (5) is constituted of a two-way clutch (25) and an electromagnetic clutch (26) having an electromagnet for causing an electromagnetic force that adheres an armature (35) and a rotor (37) to act. A phase of a retainer (31) relative to an interior member (30) is changed by action of the electromagnetic force, a roller (32) is engaged with the interior member (30) and an outer ring (27), and a rotating shaft (4) and an input shaft (21) are connected and cutoff in both rotating directions.

L'invention concerne un dispositif d'entraînement de roues électriquement entraînées dans lequel la durabilité des roulements à billes est améliorée. Ce dispositif présente une taille et un poids réduits. Ce dispositif permet d'améliorer la performance de déplacement d'un véhicule. Le dispositif d'entraînement de roues électrique de l'invention présente un dispositif de palier (2) destiné à une roue, un réducteur de vitesse planétaire (3), une partie d'entraînement (6), et un dispositif de transmission de rotation (5) pour relier un arbre de rotation (4) et un arbre d'entrée (21) disposé coaxial par rapport à l'arbre de rotation (4), par le biais d'une dentelure (27b). Le réducteur de vitesse planétaire (3) présente un galet soleil (17), des galets planétaires (15) roulant autour de la surface périphérique intérieure de l'élément extérieur (9), des tiges porteuses (14) permettant un support rotatif des galets planétaires (15) au niveau de la roue de moyeu (7). Le dispositif de transmission de rotation (5) est constitué d'un embrayage bidirectionnel (25) et d'un embrayage électromagnétique (26) présentant un électroaimant permettant la mise en action d'une force électromagnétique faisant adhérer une armature (35) et un rotor (37). Une phase d'un dispositif de retenue (31) relative à un élément intérieur (30) échangée par l'action de la force électromagnétique, un galet (32) s'emboîte dans l'élément intérieur (30) et un anneau extérieur (27), et un arbre de rotation (4) et un arbre d'entrée (21) sont reliés et séparés dans les deux directions de rotation.
