本发明提供了一种密封装置和轮毂电机驱动系统。密封装置用于密封彼此套接的第一部件和第二部件之间在径向上的间隙,密封装置包括防尘盖组件和骨架组件,防尘盖组件呈环形并用于套设于第二部件的外周并与第二部件固定连接,骨架组件呈环形并用于套设于第一部件的内周并与第一部件固定连接,防尘盖组件包括防尘盖,骨架组件包括骨架,在防尘盖的轴向上的一侧设置有第一防尘唇,第一防尘唇用于密封防尘盖与第一部件之间的间隙或密封防尘盖与骨架之间的间隙,在防尘盖的轴向上的另一侧设置有第二防尘唇,第二防尘唇密封防尘盖与骨架之间的间隙。根据本发明的密封装置能提供至少三重的密封防护部,对水和颗粒物的密封效果好。

    The invention provides a sealing device and a wheel hub motor drive system. The sealing device is used for sealing a gap between a first component and a second component which are connected with eachother in a sleeving mode in the radial direction; the sealing device comprises a dust cover assembly and a skeleton assembly; the dust cover assembly is annular and sleeves on the outer periphery of the second component and is fixedly connected with the second component; the skeleton assembly is annular and sleeves on the inner periphery of the first component and is fixedly connected with the first component; the dust cover assembly comprises a dust cover; the skeleton assembly comprises a skeleton; a first dust lip is arranged on one side of the dust cover in the axial direction, and the first dust lip is used to seal the gap between the dust cover and the first component or the gap between the dust cover and the skeleton; and a second dust lip is arranged on the other side of the dust cover in the axial direction, and the second dust lip is used to seal the gap between the dust cover and the skeleton. The sealing device provided by the invention can provide at least triple sealing protection parts, and has a good sealing effect on water and particulate matters.
