Title
(EN) IN-WHEEL MOTOR DRIVE DEVICE
(FR) DISPOSITIF D’ENTRAÎNEMENT DE MOTEUR INCORPORÉ EN ROUE
(JA) インホイールモータ駆動装置
Abstract
(EN)
Provided is an in-wheel motor drive device 21 in which a semi-solid lubricant J is present in a spline-fitted portion M where an output gear shaft 37 and a hub wheel 51 are coupled, and an opening of a hollow portion of the hub wheel 51 is sealed with an annular first seal member S1 disposed on the inboard side relative to the spline-fitted portion M, and with a second seal member S2 disposed on the outboard side relative to the spline-fitted portion M. The output gear shaft 37 is provided with a hole portion 65 having one end that opens at an end surface 37c on the outboard side, and another end that opens at a surface E exposed to the internal space of a casing 22.

La présente invention concerne un dispositif d'entraînement de moteur encorporé en roue (21) dans lequel un lubrifiant semi-solide (J) est présent dans une partie ajustée par cannelures (M) où un arbre d'engrenage de sortie (37) et une roue à moyeu (51) sont couplés, et une ouverture d'une partie creuse de la roue à moyeu (51) est étanchéifiée avec un premier élément d'étanchéité annulaire (S1) disposé sur le côté intérieur par rapport à la partie ajustée par cannelures (M), et un second élément d'étanchéité (S2) disposé sur le côté extérieur par rapport à la partie ajustée par cannelures (M). L'arbre d'engrenage de sortie (37) est pourvu d'une partie à trou (65) qui a une extrémité qui s'ouvre au niveau d'une surface d'extrémité (37c) sur le côté extérieur, et une autre extrémité qui s'ouvre au niveau d'une surface (E) exposée à l'espace interne d'un carter (22).
(JA)
出力歯車軸37とハブ輪51とを連結したスプライン嵌合部Mに半固体状潤滑剤Jが介在し、ハブ輪51の中空部の開口が、スプライン嵌合部Mよりもインボード側に配置された環状の第1シール部材S1と、スプライン嵌合部Mよりもアウトボード側に配置された第2シール部材S2とで封口されたインホイールモータ駆動装置21である。出力歯車軸37に、一端がアウトボード側の端面37cに開口すると共に、他端がケーシング22の内部空間への露出面Eに開口した孔部65を設ける。
