The invention belongs to the field of vehicles and discloses an internal speed change hub convenient to disassemble, which includes a shaft, a hub shell which is rotatably mounted on the shaft and isused 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; and a first-stage gear ring which comprises an inner diameter which is gradually reduced, so that when the driving body is axially drawn out, the first-stage gear ring generates radial compression on the first-stage claw spine to force the first-stage claw spine to retract. Compared with the prior art, the technical scheme has the advantages that the driving body is easier to disassemble and cannotbe clamped by the gear ring.
本发明属于车辆领域公开一种便于拆解的内变速花鼓,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,可旋转的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;所述一级齿环包括逐渐缩小的内径,以使得所述驱动体被轴向抽出时一级齿环对所述一级爪棘产生径向压迫,迫使所述一级爪棘回缩。本技术方案相对现有技术而言驱动体更容易拆卸,不会被齿环卡住。
