    • An automatic centrifugal clutch is arranged at the rear of an engine of a motorcycle, and a belt type continuously variable transmission and a gear type speed reduction device are arranged on opposite sides of the clutch whereby a space at the rear of the engine is effectively utilized, and a space for installing a kick starter is secured externally of the belt type continuously variable transmission. An output shaft of a reduction device and an intermediate shaft of the reduction device are arranged on opposite sides of a plane extending so as to include axes of a crankshaft and an input shaft whereby the longitudinal length of a power transmission device is shortened. An opening of a cooling air discharge passage is provided to face the automatic centrifugal clutch at the front end of the reduction device whereby the automatic centrifugal clutch can be effectively cooled while effectively utilizing the space. Two mating surfaces formed in the case means are offset from each other, whereby the space within the case means can be effectively utilized. Furthermore, a reed valve and a starter motor are arranged with the crankshaft interposed therebetween on a crank case whereby there is secured a space for efficiently arranging an intake system leading to the reed valve.
    • 在摩托车的发动机的后部配置有自动离心式离合器,在离合器的两侧配置有带式无级变速器和齿轮式减速装置,能够有效地利用发动机后方的空间 并且在带式无级变速器的外部固定有用于安装脚踏起动器的空间。 减速装置的输出轴和减速装置的中间轴被布置在延伸以包括曲轴和输入轴的轴线的平面的相对侧上,由此缩短了动力传递装置的纵向长度。 设置冷却空气排出通道的开口以面对减速装置的前端处的自动离心式离合器,由此能够有效地利用自动离心式离合器而有效地利用空间。 形成在壳体装置中的两个配合表面彼此偏移,从而可以有效地利用壳体装置内的空间。 此外,簧片阀和起动电动机被布置成曲轴插入在曲轴箱中,由此固定有用于有效地布置通向簧片阀的进气系统的空间。

    • In a vehicle travelling by use of a travelling drive source such as an engine or a motor, the gear shift ratio of a continuously variable transmission B can be changed by increasing or decreasing the width of a groove in a driving pulley 19 of the continuously variable transmission B by a gear shift ratio changing device 61 using a motor 62 as a drive source. The motor 62 is controlled on the basis of output signals from a throttle opening degree sensor, an engine rotational speed sensor and a vehicle speed sensor, thereby enabling an energy-saving travelling suited to an operational condition of the travelling drive source or a travelling condition of the vehicle. The gear shift ratio changing device 61 is supported in a floating manner within a casing 3, 8 for the continuously variable transmission B. This achieves not only a reduction in size of a power unit, but also ensures that any operational sound of the motor 62 is prevented from leaking out, and any vibration from the engine or a wheel cannot be transmitted to the gear shift ratio changing device 61.
    • 在通过使用诸如发动机或电动机的行驶驱动源行驶的车辆中,无级变速器B的变速比可以通过增加或减小连续变量的驱动带轮19中的槽的宽度来改变 变速箱B由变速比变更装置61使用电动机62作为驱动源。 基于来自节气门开度传感器,发动机转速传感器和车速传感器的输出信号来控制电动机62,从而能够进行适合行驶驱动源的运行状态的节能行驶或行驶状态 的车辆。 变速比改变装置61以浮动方式支撑在用于无级变速器B的壳体3,8内。这不仅实现了动力单元的尺寸的减小,而且还确保了电动机62的任何操作声音 防止发动机或车轮的振动不能传递到变速比变更装置61。
