    • A variable ratio drive pulley, of the type employed in snowmobiles to transmit a drive from the snowmobile engine via a belt transmission to the snowmobile track, has a fixed flanged and an opposed movable flange which co-operate to drive the belt. The movable flange is spring loaded away from the fixed flange and centrifugal means are included to overcome the spring force and urge the movable flange towards the fixed flange with a force that increases with the speed of rotation. The centrifugal means comprises a number of pivoted levers each having a roller cooperating with a ramp, and the pulley includes means whereby the position of the ramp can be rapidly adjusted without disassembly of the drive pulley, to vary the response of the drive pulley to different operating conditions.
    • 用于雪地车辆中的类型的变速传动皮带轮,用于将来自雪地车辆发动机的驱动通过皮带传动装置传递到雪地车道上,具有固定的凸缘和相对的可动凸缘,该可动凸缘协同操作以驱动皮带。 可移动法兰从固定法兰弹簧加载,包括离心装置以克服弹簧力,并以随旋转速度增加的力将可动凸缘推向固定法兰。 离心装置包括多个枢转杆,每个转动杆具有与斜面协作的辊,并且滑轮包括装置,由此可以快速地调整斜面的位置而不拆卸驱动滑轮,以将驱动滑轮的响应改变为不同的 运行条件。
