Title
(EN) WHEEL ASSEMBLY WITH IN-WHEEL MOTOR
(FR) ENSEMBLE ROUE AVEC MOTEUR DANS LA ROUE
Abstract
(EN)
A wheel assembly with an in-wheel motor includes a motor (700) for driving a wheel (10), which is arranged in the wheel (10); a reduction mechanism (200) which reduces the rate of rotational output of the motor (700) and transmits the resultant rotational output to the wheel (10); an oil tank (310) in which oil collects; an oil pump (300) that is driven by rotational output of the motor (700); and an oil flow path (320) that leads oil from the oil pump to at least one of the motor (700) and the reduction mechanism (200). The oil tank (310) is arranged below the reduction mechanism (200), farther toward a vehicle inside in a vehicle width direction than a brake dust cover (112), and farther toward the vehicle outside in the vehicle width direction than a lower ball joint (500).
(FR)
Ensemble roue avec un moteur dans la roue comprenant un moteur (700) pour entraîner une roue (10), qui est disposé dans la roue (10); un mécanisme (200) réducteur qui réduit la vitesse angulaire de sortie rotative du moteur (700) et transmet la sortie rotative résultante à la roue (10); un réservoir d'huile (310) qui collecte l'huile; une pompe (300) à huile qui est entraînée par la sortie rotative du moteur (700); et un passage (320) de flux d'huile qui conduit l'huile depuis la pompe à huile jusqu'au moteur (700) et/ou au mécanisme (200) réducteur. Le réservoir (310) d'huile est placé sous le mécanisme (200) réducteur, plus avant vers l'intérieur du véhicule dans la direction de la largeur du véhicule qu'un garde boue (112) de frein, et plus avant vers l'extérieur du véhicule dans la direction de la largeur du véhicule qu'un joint (500) rotule inférieur.
