    • An epicyclic change speed gear comprises a fixed spindle (4) and side-by-side sun pinions (1, 2, 3) rotatable on the spindle. A gear selector key (5) is adapted for selective cooperative engagement with one of the sun pinions to lock that pinion to the spindle. The key (5) is operated by a sleeve (15) disposed for rotational movement relative to the spindle (4). Rotation of the sleeve (15) displaces the key (5) axially to lock the selected sun pinion. One or both axial ends of the sleeve (15) are angled such that different degrees of rotation cause different axial displacements of the key (5) and cause different sun pinions to be locked.
    • 行星齿轮变速齿轮包括可在主轴上旋转的固定心轴(4)和并排的太阳小齿轮(1,2,3)。 齿轮选择器键(5)适于与太阳小齿轮之一选择性协作接合以将该小齿轮锁定到主轴上。 钥匙(5)由设置成相对于主轴(4)旋转运动的套筒(15)操作。 套筒(15)的旋转使键(5)轴向移位以锁定所选择的太阳小齿轮。 套筒(15)的一个或两个轴向端部成角度,使得不同的旋转角度引起键(5)的不同的轴向位移,并导致不同的太阳小齿轮被锁定。

    • An epicyclic bicycle change speed gear hub comprises primary and secondary sun pinions (12) and (13) disposed side-by-side on the spindle (14) of the hub. A split selector key (11) comprising first and second parts (15 and 16) is mounted on a support rod (17) for relative movement axially of the hub. Dogs (19 and 21) on respective parts (15 and 16) can be brought into selective cooperative engagement with splines (31 and 32) inwardly of the sun pinions (12 and 13) to lock the selected pinion to the spindle (14) in drive transmission mode. The selector key (11) is movable axially into abutment with a selector sleeve to effect axial adjustment thereof against the restraint of a return spring to provide for change between high and low gears thus providing a compact arrangement.
    • 行星式自行车变速齿轮毂包括并排设置在轮毂的心轴(14)上的初级和次级太阳小齿轮(12)和(13)。 包括第一和第二部分(15和16)的分割选择器键(11)安装在支撑杆(17)上,用于轮毂的轴向相对移动。 相应部件(15和16)上的狗(19和21)可以与太阳小齿轮(12和13)内的花键(31和32)选择性协作接合,以将所选择的小齿轮锁定到主轴(14)上 驱动传输模式。 选择器键(11)可轴向移动以与选择器套筒邻接以对其进行轴向调节,以克服复位弹簧的限制,以提供高档和低档之间的变化,从而提供紧凑的布置。
