    • A centrifugal clutch comprises a driving plate having oppositely facing surfaces secured to an input shaft operatively connected to a driving source, a cylindrical bottomed drum detachably secured to an end, projecting from the input shaft, of an output shaft concentrically and relatively rotatably disposed within the input shaft, the cylindrical bottomed drum surrounding the driving plate, and a plurality of clutch springs each connected to each of a plurality of shoes which are supported on the plate for movement toward and away from an inner peripheral surface of the drum respectively by a plurality of stub shafts parallel to the input shaft, the clutch spring providing a spring force in a direction away from the inner peripheral surface of the drum. In the centrifugal clutch, a group of the shoes and clutch springs having respective weight and load which are set to transmit a relatively large torque between the input shaft and the output shaft are arranged closer to the closed end of the drum, and another group of shoes and clutch springs having respective weight and load set so as to transmit a relatively small torque between the input shaft and the output shaft are arranged closer to an opened end of the drum.

    • A power transmission for a two-wheeled vehicle includes a variable-diameter drive pulley mechanism (2) mounted on a drive shaft (1) connected to an engine (E), a variable-diameter driven pulley mechanism (22) mounted on a driven shaft (18) operatively coupled with a driven wheel (W), and a clutch (36) mounted coaxially on the driven shaft (18) and operatively connected to the driven pulley mechanism (22). The drive and driven pulley mechanisms (2,22) are interconnected by a V-belt (7). The drive and driven pulley mechanisms (2,22) have axially movable members (5,24) located on opposite sides of the V-belt (7) adjacent to the engine (E) and the clutch (36) to allow parallel displacement of the V-belt (7) during the changing of the diameters of the pulley mechanisms (2,22), to prevent belt twisting or distortion and to prevent the belt (7) and pulley mechanisms (2,22) from being loaded while the vehicle is moved around with the engine (E) turned off.
    • 用于两轮车辆的动力传动装置包括安装在与发动机(E)连接的驱动轴(1)上的可变直径驱动滑轮机构(2),可变直径从动滑轮机构(22),其安装在驱动 与从动轮(W)可操作地连接的轴(18)和同轴地安装在从动轴(18)上并可操作地连接到从动滑轮机构(22)的离合器(36)。 驱动和从动皮带轮机构(2,22)通过V形皮带(7)相互连接。 驱动和从动皮带轮机构(2,22)具有位于与发动机(E)和离合器(36)相邻的V形皮带(7)的相对侧上的轴向可移动构件(5,24),以允许平行位移 在改变皮带轮机构(2,22)的直径期间的V形皮带(7),以防止皮带扭曲或扭曲,并且防止皮带(7)和滑轮机构(2,22)被装载 车辆随着发动机(E)关闭而移动。
