The present invention relates to a wheel motor structure which has enhanced dustproof and waterproof effects and, simultaneously, can have increased heat radiation efficiency. Disclosed is the wheel motor structure comprising: a stator; a rotor; a cover coupled to one side of the rotor such that one side of the stator is covered; a coupling shaft penetrating each of the stator and the cover; and an oil seal disposed in the space between the cover and the coupling shaft so as to seal the space, wherein the cover has heat-radiating fins extending in the radial direction and protruding from both surfaces thereof. Therefore, the wheel motor structure has enhanced dustproof and waterproof effects and, simultaneously, can have increased heat radiation efficiency.

    La présente invention concerne une structure de moteur de roue qui a des effets d'étanchéité à la poussière et à l'eau améliorés et qui, simultanément, peut avoir une efficacité accrue en matière de rayonnement thermique. La présente invention concerne la structure de moteur de roue comprenant : un stator; un rotor; un couvercle couplé à un côté du rotor de telle sorte qu'un côté du stator est recouvert; un arbre de couplage pénétrant dans chacun du stator et du couvercle; et un joint étanche à l'huile disposé dans l'espace entre le couvercle et l'arbre de couplage de façon à sceller de manière étanche l'espace, le couvercle ayant des ailettes de rayonnement thermique s'étendant dans le sens radial et faisant saillie à partir des deux surfaces de celui-ci. Par conséquent, la structure de moteur de roue a des effets d'étanchéité à la poussière et à l'eau améliorés et, simultanément, peut avoir une efficacité accrue en matière de rayonnement thermique.

    본 발명은, 방진 및 방수 효과가 보다 향상되는 동시에 방열 효율이 보다 증가될 수 있는 휠 모터 구조체에 있어서, 고정자, 회전자, 상기 고정자의 일 면이 엄폐되도록 상기 회전자의 일 면과 결합되는 커버, 상기 고정자 및 상기 커버에 각각 관통되는 결합축 및 상기 커버와 상기 결합축 사이 공간에 배치되어 상기 공간을 밀폐하는 오일실(oil seal)을 포함하고, 상기 커버는 양면에 방사 방향으로 연장되는 방열핀이 돌출 형성되는, 휠 모터 구조체를 개시한다. 이에 따라, 휠 모터 구조체의 방진 및 방수 효과가 보다 향상되는 동시에 방열 효율이 보다 증가될 수 있다.
