The present invention provides a transmission system (12) comprising a first pulley (211) connected to an input (11) by a cable (40) such that movement of the input causes rotation of the first pulley. The first pulley comprises an annular recess (25) between a first side (17) of the first pulley and a second side (19) of the first pulley. The annular recess is adapted to receive the cable such that the cable is supported by the first pulley. The first pulley also comprises a pair of support surfaces (31) located in the annular recess, which are moveable in a lateral direction relative to thesides of the pulley between a spaced condition, wherein the first pulley is at a first diameter and the pair of support surfaces do not engage the cable, and a meshed condition, wherein the first pulley is at a second diameter and the pair of support surfaces support the cable, the second diameter being larger than the first diameter.

    本发明提供了一种传动系统(12),该传动系统包括第一皮带轮(211),该第一皮带轮通过缆绳(40)连接至输入端(11),使得输入端的运动引起第一皮带轮的旋转。第一皮带轮包括在第一皮带轮的第一侧面(17)和第一皮带轮的第二侧面(19)之间的环形凹槽(25)。环形凹槽适于容纳缆绳,使得缆绳由第一皮带轮支撑。第一皮带轮还包括位于环形凹槽中的一对支撑表面(31),该支撑表面可相对于皮带轮的侧面在间隔状态和啮合状态之间沿横向方向移动,其中间隔状态是第一皮带轮位于第一直径,并且该一对支撑表面不与缆绳啮合;其中啮合状态是第一皮带轮位于第二直径,一对支撑表面支撑缆绳,第二直径大于第一直径。
