The invention belongs to the field of vehicles, and discloses an internal speed change hub which comprises a shaft, a hub shell which is rotatably mounted on the shaft and is used for driving the wheel to rotate; a first-stage driving body which is rotatably mounted on the shaft, is partially accommodated in the hub shell and is used for driving the hub shell; a first-stage claw spine which is arranged on the first-stage driving body, and the first-stage claw spine is meshed with a first-stage gear ring on the inner wall of the hub shell so as to drive the hub shell. Compared with the prior art, the technical scheme has the advantages that the axial space is smaller, so that the hub is suitable for vehicles with motors arranged in the middle and has better sealing performance.

    本发明属于车辆领域公开一种内变速花鼓,所述包括:轴;花鼓壳体,可旋转地安装在所述轴上,用于驱动车轮转动;一级驱动体,可旋转地安装在所述轴上并部分收容在所述花鼓壳体内,用于驱动所述花鼓壳体;设置在所述一级驱动体上的一级爪棘,所述一级爪棘与花鼓壳体内壁上的一级齿环啮合以驱动所述花鼓壳体。本技术方案相对现有技术而言轴向空间更小,使得花鼓适用于中置电机的车辆,并且具有更好的密封性。
