DOWN-WAY TRANSPORTING UNIT Russian patent published in 2011 - IPC F16D33/20 B65G23/00 

FIELD: machine building.

SUBSTANCE: down-way transporting unit consists of motor drive and of hydro-dynamic clutch. From the side of the drive the hydro-dynamic clutch has a pump wheel with a multitude of blades, while from the side of power take-off it has a turbine wheel with a multitude of blades together forming toroid working space filled with working substance. In the section of working space along circumference in the direction from an upper rim of the working wheel to the crown of the blade the blades of the pump wheel are inclined opposite to direction of rotation of the pump wheel. In the direction from the upper rim of the working wheel to the crown of the blade the blades of the turbine wheel are inclined in the direction of rotation of the turbine wheel drive. The unit operates under generator and motor modes depending which of the two - pump or turbine wheel - rotates faster.

EFFECT: reduced torque in hydro-dynamic clutch.
