Automatic transmission

摘要

Automatic transmission comprising: planetary gears arranged coaxially in a row, each planetary gear comprising a sun wheel, a planetary carrier carrying pivoted planetary wheels and an annulus gear, an input column connected to a sun wheel of a first planetary gear, a general gear positioned adjacent to the row of planetary gears next to a last planetary gear, n mediator gears mounted on an output column and connected to the output column via a freewheel assembly so the mediator gears are freely rotatable in one direction relative to the output column, each mediator gear in engagement with one of the planetary wheels, wherein a planetary carrier of the last planetary gear is fixed to the general gear, and a planetary carrier of each but the last planetary gear connected to a sun wheel of a following planetary gear, wherein rotation of any of the mediator gears can be stopped selectively.

1. An automatic transmission device comprising:
a number n of planetary gears arranged coaxially in a row, each planetary gear comprising a sun wheel, a planetary carrier carrying pivoted planetary wheels and an annulus gear, an input column connected to a sun wheel of a first planetary gear of the row of planetary gears, at least one general gear positioned adjacent to the row of planetary gears next to a last planetary gear, n mediator gears, each mounted on an output column and connected to the output column via a freewheel assembly such that the mediator gears are freely rotatable in one direction relative to the output column; each mediator gear being in engagement with one of the planetary wheels,wherein a planetary carrier of the last planetary gear is fixed to the at least one general gear, anda planetary carrier of each but the last planetary gear being connected to a sun wheel of a following planetary gear positioned adjacently towards the last planetary gear,wherein rotation of any of the mediator gears can be stopped selectively.
