| 摘要 |
The invention includes an irreversible transmission device which is mounted between an input and an output shaft and which comprises a casing (2) supporting both the input shaft (4) and the output shaft (6), further a displaceable body (12) rotating in affixed manner jointly with the output shaft (6) while being displaceable relative to said output shaft, this displaceable body (12) being displaceable between a locked position and a position of free rotation relative to the casing (2), said device further comprising a. cam (8) on the input shaft (4) able to force the displaceable body (12) from its locked position toward its position of free rotation, and. when the displaceable body (12) is in its position of free rotation, said cam being able to drive both said displaceable body and the output shaft (6) into rotation, and also comprising restoring means (20) to return the displaceable body (12) into its locked position absent action by the cam (8) on the displaceable body (12). |
