Abstract

A planetary gear mechanism which has at least one drive unit, at least one output unit and a freewheel unit. The freewheel unit is provided for blocking a moment which is introduced at the output unit.

Claims (11)

1. Planetary gear mechanism comprising:

at least one drive unit;

at least one output unit;

at least one planetary gear unit having at least one planetary gear, which is of a two part configuration; and

a freewheeling unit, which is provided for blocking a moment introduced independently of a rotational direction of the moment at the output unit, having a wrap spring.

2. The planetary gear mechanism according to claim 1 , wherein the freewheeling unit is self-locking.

3. The planetary gear mechanism according to claim 1 , wherein a first part of the planetary gear which is connected to the drive unit is decoupled from a second part of the planetary gear which is connected to the output unit.

4. The planetary gear mechanism according to claim 1 , wherein the freewheeling unit is provided for forwarding a moment which is introduced at the drive unit from the first part to the second part of the planetary gear.

5. The planetary gear mechanism according to claim 1 , wherein the freewheeling unit is provided for diverting the moment which is introduced at the output unit away from the second part of the planetary gear to a planetary gear carrier.

6. The planetary gear mechanism according to claim 1 , wherein the freewheeling unit is provided for forwarding a moment which is introduced at the drive unit to the output unit.

7. The planetary gear mechanism according to claim 6 , the freewheeling unit is provided for forwarding the introduced moment to the output unit independently of a rotational direction of the moment which is introduced at the drive unit.
