The invention, which relates to the field of vehicle accessories, discloses a combined axle structure capable of freely shifting gears for transmission. The combined axle structure comprises a threaded cylinder, an inner cylinder and an outer hub which are sleeved together. The threaded cylinder is composed of a driving end plate, a forward spinning cylinder, a backward spinning cylinder and a smooth rotating cylinder, all of which are sequentially reduced in outer diameter. A clutch baffle plate is arranged on each of the two spinning cylinders; the inner cylinder is sleeved on the threaded cylinder, the inner cylinder is internally provided with two clutch check rings, the clutch baffle plate on the forward spinning cylinder is arranged between the two clutch check rings, the smooth rotating cylinder matches a smooth rotation disc, the smooth rotation disc is provided with a traction fork inserted into the two clutch baffle plates, a fixed rotation stopping disc is arranged outside the smooth rotation disc, and the outer hub sleeves the outside of the inner cylinder. After assembly, the combined axle structure can rotate forwards or rotate reversely.
本发明涉及交通工具配件领域,特别公开了一种可自由换档传动的组合轮轴结构,它由螺纹筒、内筒和外轮毂套在一起组成,螺纹筒由外径依次减小的驱动端板、正旋丝筒、反旋丝筒和平滑旋筒组成,两个旋丝筒上分别有一个离合档盘,内筒套在螺纹筒上,内筒内由两个离合挡圈,正旋丝筒上的离合档盘位于两个离合挡圈之间,平滑旋筒配套平滑旋盘,平滑旋盘上有牵制叉,牵制叉插入两个离合档盘内,平滑旋盘外为固定阻旋盘,外轮毂套在内筒外。组装后的本发明既可以正转,也可以反转。
