无级变速器主动带轮
摘要：
一种用于CVT的主动带轮，该主动带轮具有固定滑轮、固定地连接至固定滑轮的固定滑轮轴、可动滑轮、固定地连接至可动滑轮的可动滑轮轴、星形轮和至少一个离心式致动器。固定滑轮轴至少部分地布置在可动滑轮轴的内部。可动滑轮在轴向上布置在星形轮与固定滑轮之间。偏置构件使可动滑轮沿轴向偏置远离固定滑轮。扭矩传递组件操作性地连接至固定滑轮和可动滑轮中的至少一者。扭矩传递组件在固定滑轮与可动滑轮之间传递扭矩。偏置构件、至少一个离心式致动器和扭矩传递组件布置在固定滑轮轴和可动滑轮轴的径向外侧。
摘要（英）：

A drive pulley for a CVT has a fixed sheave, a fixed sheave shaft fixedly connected to the fixed sheave, a movable sheave, a movable sheave shaft fixedly connected to the movable sheave, a spider and at least one centrifugal actuator. The fixed sheave shaft is disposed at least in part inside the movable sheave shaft. The movable sheave is disposed axially between the spider and the fixed sheave. A biasing member biases the movable sheave axially away from the fixed sheave. A torque transfer assembly is operatively connected to at least one of the fixed sheave and the movable sheave. The torque transfer assembly transfers torque between the fixed sheave and the movable sheave. The biasing member, the at least one centrifugal actuator and the torque transfer assembly are disposed radially outward of the fixed and movable sheave shafts.
