周转轮系--无级变速器设计
摘要
本课题是一种无级变速器，其是连续变化的驱动皮带轮和从动皮带轮之间的传动比（传动比被定义为每分钟转数或速度比），更具体地说，涉及一种压实的无级变速器中的机动车辆用。
它是已知的一种类型的无级变速器的具有V型皮带驱动和从动带轮之间延伸，并且通过改变在两个V形的开口（S）的大小控制的从动带轮的转数主动和从动滑轮。因此，在皮带轮和皮带轮的有效直径的带的位置可以改变，并且可以连续地改变输入轴和在所述无级变速器的输出轴之间的转速比。
它也被称为以形成从预定数目的金属箍，在它们的纵向可移动的V形块件安装的无级变速传动装置，该部件被连接在一起，并延长箍的总圆周周围。驱动滑轮的驱动力，然后由V形块构件的运动传递给从动皮带轮。

Continuously Variable Transmission
Abstract
The present invention relates to a continuouslyvariable transmissionwhich continuouslyvaries the transmission ratio(transmission ratio being defined as the RPM or speed ratio) between a driving pulley and a driven pulley, and more particularly to a compacted continuouslyvariable transmission used in a motorizedvehicle.
It is known that one type of a continuouslyvariable transmission has a V-belt extending between a driving and driven pulley and controls the number of the revolutions of a driven pulley byvarying the size of a V-shaped opening(s) in both the driving and driven pulleys. Thus, the position of the belt on the pulley and the effective diameter of the pulley can bevaried, and it is possible to continuouslyvary the RPM ratio between the input shaft and the output shaft in the continuouslyvariable transmission.
It is also known to form a continuouslyvariable transmission means from a predetermined number of metallic hoops, uponwhich longitudinally shiftable V-shaped block members are mounted, the members are linked together and extend around the total circumference of the hoops. The driving force of the driving pulley is then transmitted to the driven pulley by the movement of the V-shaped block members.
