| 摘要 |
The present invention relates to a stepless variable transmission device (100) with parallel low gear wheel group, which is the first case that a low gear transmission wheel group (102) equipped with a one-way transmission unit (111), which transmits with fixed speed ratio in same rotary direction, is installed between the input shaft (101) and the output shaft (103) of a stepless variable transmission device (100); and which is installed with the clutch device (212) with angular displacement difference and/or the clutch device (222) for eliminating the vibration produced by the hetero-shaft type stepless variable transmission device (100) and the low gear transmission wheel group (102), the both do not operate with fully same speed ratio, for overloaded transmission. |
