Title (EN) ELECTRIC DRIVE DEVICE AND ELECTRIC POWER STEERING DEVICE
(FR) DISPOSITIF D'ENTRAÎNEMENT ÉLECTRIQUE ET DISPOSITIF DE DIRECTION ASSISTÉE ÉLECTRIQUE
(JA) 電動駆動装置及び電動パワーステアリング装置
Abstract:
(EN) Provided is an electric drive device in which heat-dissipating sections (15A) (15B) that transfer at least heat generated by a power supply circuit unit (17) and power conversion circuit units (16) to a motor housing (11) are formed on an end surface section (15) of the motor housing (11) on the opposite side from an output section of a rotating shaft (23) of an electric motor. In addition, a watertight lid member (35) that covers a through hole (41) through which the rotating shaft passes and the end of the rotating shaft (23) from the exterior is attached to the end surface section (15) around the through hole (41), and a waterproof breathable membrane (44) that prevents the passage of moisture while allowing the passage of air and water vapor is provided to part of the watertight lid member.
(FR) L'invention concerne un dispositif d'entraînement électrique dans lequel des sections de dissipation de chaleur (15A) (15B) qui transfèrent au moins la chaleur générée par une unité de circuit d'alimentation électrique (17) et des unités de circuit de conversion de puissance (16) à un carter de moteur (11) sont formées sur une section de surface d'extrémité (15) du carter de moteur (11) du côté opposé à une section de sortie d'un arbre rotatif (23) d'un moteur électrique. De plus, un élément de couvercle étanche à l'eau (35) qui recouvre un trou traversant (41) à travers lequel passe l'arbre rotatif et l'extrémité de l'arbre rotatif (23) depuis l'extérieur est fixé à la section de surface d'extrémité (15) autour du trou traversant (41), et une membrane imper-respirante (44) qui empêche le passage d'humidité tout en permettant le passage d'air et de vapeur d'eau est fournie à une partie de l'élément de couvercle étanche à l'eau.
(JA) 電動モータの回転軸(23)の出力部とは反対側のモータハウジング(11)の端面部(15)に、少なくとも電源回路部(17)及び電力変換回路部(16)で発生した熱をモータハウジング(11)に伝熱させる放熱部(15A)(15B)が形成されている。また、回転軸が貫通する貫通孔(41)の周囲の端面部(15)に、貫通孔(41)と回転軸(23)の端部までを外側から覆う水密蓋部材(35)が取り付けられ、水密蓋部材の一部に、水分の通過を防止し空気や水蒸気の通過を許す防水通気膜(44)が設けられている。
