Mechanical stageless torque converter - planetary wheel units obviating power losses and is suitable for comparatively high speeds and torques

摘要

Planetary gear comprising at least three planet wheel units, in which two planet wheel units are connected by a common hollow wheel and the bearer of one of these units is engaged with the third planet wheel unit via a transmission gearing fitted in the support hollow wheel. The planet wheel of the third unit can support via a free motion to a hollow wheel opposed to the input direction of rotation, and the bearer of this planet wheel unit is also that for the second planet wheel unit. The turbine of a fluid coupling is connected with the drive shaft, the fluid couplings pump is connected via a shaft to the common hollow wheel of the first two planet wheel units. The fluid coupling can be replaced by, for instance, a plate coupling, and the fluid coupling turbine can be firmly connected to the hollow wheel with bearer or hollow wheel with bearer.
