摘要： A shift adjusting device includes a cam plate and an arm. The cam plate is pivotable and operatively connected to a change speed interlocking mechanism extending between a shift pedal and a belt type stepless change speed device. The arm is also pivotable and operatively connected to a changeover interlocking mechanism extending between a switch lever and a backward/forward drive changeover device. The arm has a pin for engaging a control slot formed in the cam plate. The control slot includes an arcuate forward drive slot portion and an arcuate backward drive slot portion. When the switch lever is in a forward drive position, the pin lies in the forward drive slot portion. The forward drive slot portion allows a full stroke depression of the shift pedal, whereby a forward speed may be selected between minimum speed and maximum speed. When the switch lever is in a backward drive position, the pin lies in the backward drive slot portion. The backward drive slot portion allows only a half stroke depression of the shift pedal, whereby a backward speed may be selected between minimum speed and half the maximum speed.
摘要翻译：换档调节装置包括凸轮板和臂。凸轮板可枢转并且可操作地连接到在换档踏板和带式无级变速装置之间延伸的变速联锁机构。臂也可枢转并且可操作地连接到在开关杆和向后/向前驱动切换装置之间延伸的转换互锁机构。臂具有用于接合形成在凸轮板中的控制槽的销。控制槽包括弧形前进驱动槽部分和弧形向后驱动槽部分。当开关杆处于正向驱动位置时，该销位于前部驱动槽部分。前进驱动槽部分允许换档踏板的全行程压下，从而可以在最小速度和最大速度之间选择前进速度。当开关杆处于向后驱动位置时，该销位于向后的驱动槽部分中。向后的驱动槽部分仅允许换档踏板的半冲程压下，从而可以在最小速度和最大速度的一半之间选择后退速度。
