Abstract

A clutch assembly or module that includes multiple components and one-way clutches. The clutch assembly or module functions as a releasable torque transmitting mechanism that provides a mechanical engagement between mating parts wherein the multiple components and one-way clutches cooperate to control the torque flow path between a drive or input member and a driven or output member.

First claim

What is claimed is:

1. A clutch assembly comprising:
a first shaft rotatable about a rotational axis;
a second shaft rotatable about the rotational axis;
a first component directly connected to the first shaft;
a second component directly connected to the second shaft;
a third component directly connected to the second component wherein the third component does not directly contact either of the first shaft and the second shaft;
a passive one-way clutch between the first component and the third component; and
an active one-way clutch between the first component and the second component, the active one-way clutch including an electromagnetic actuator including a stator having at least one inductive coil and a translator, the at least one inductive coil acts on the translator wherein the translator moves axially in the direction of the rotational axis.

2. The clutch assembly of claim 1 wherein:
the first component includes a first surface and a second surface;
the second component includes a first surface;
the third component includes a first surface;
the passive one-way clutch coupling the first surface of the first component to the first surface of the third component; and
the active one-way clutch coupling the second surface of the first component in the first surface of the second component.

3. The clutch assembly of claim 2 wherein:
the first component is disposed between the first surface of the third component and the first surface of the second component.

4. The clutch assembly of claim 1 wherein:
the first component includes a disc-shaped member directly connected to and extending radially outward from the first shaft; and
the second component includes a disc-shaped member directly connected to and extending radially outward from the second shaft; and
the third component includes a disc-shaped member directly connected to the second component and extending radially inward toward the first shaft wherein the disc-shaped member of the second component and the disc-shaped member of the third component are axially spaced with the disc-shaped member of the first component positioned between the disc-shaped members of the second component and the third component.

5. The clutch assembly of claim 1 wherein:
the passive one-way clutch includes a pocket in a first surface of the first component and a locking element extending out of the pocket and past the first surface of the first component and engaging the first surface of the third component; and
the active one-way clutch includes a locking element deployable between a second surface of the first component and the first surface of the second component.

6. The clutch assembly of claim 5 wherein:
the first surface of the third component includes a plurality of notches; and
the second surface of the first component includes a plurality of notches.

7. The clutch assembly of claim 1 wherein:
the passive one-way clutch includes a locking element, the locking element engaging a notch in the third component; and
the active one-way clutch includes a locking element, the locking element engaging a notch in the first component.

8. A clutch assembly comprising:
an input shaft, rotatable about a first shaft rotational axis, receiving an input from a motor;
an output shaft, rotatable about a second shaft rotational axis, transmitting power to a vehicle wheel;
a first component connected to and rotating with the input shaft;
a second component connected to and rotating with the output shaft;
a passive one-way clutch between the first component and the second component;
an active one-way clutch between the first component and the second component;
the passive one-way clutch including the first component having a pocket and a strut in the pocket wherein the strut is on a first shaft side of the passive one-way clutch;
the second component including a first surface and a second surface with an opening between the first surface and the second surface of the second component, the first component is disposed in the opening;
the first component, including a first surface facing the first surface of the second component and a second surface facing the second surface of the second component;
the strut of the passive one-way clutch located in a pocket in the first component and extending from the pocket and above the first surface of the first component to the first surface of the second component and coupling the first component and the second component in a first direction of rotation only and allowing the first component to overrun the second component in a second direction of rotation; and
the active one-way clutch including a strut moveable between a non-deployed position wherein the strut is below the second surface of the second component to a deployed position wherein the strut extends above the second surface of the second component to the second surface of the first component, the strut coupling the first component and in the second direction of rotation only and allowing the first component to overrun the second component in the first direction of rotation.

9. The clutch assembly of claim 8 wherein the active one-way clutch includes:
an actuator, the actuator including a stator and a translator, the stator including at least one electromagnetically inductive coil; and
a spring positioned between the translator and the strut mounted in the second component.

10. The clutch assembly of claim 9 wherein:
the spring of the actuator holds the strut between the second surface of the first component and the second surface of the second component in the deployed position coupling the second component to the first component in one direction and overrunning the first component in the opposite direction.

11. A clutch assembly comprising:
a first shaft rotatable about a first shaft rotational axis;
a second shaft rotatable about a second shaft rotational axis;
a first component connected to the first shaft;
a second component connected to the second shaft;
a third component connected to the second component;
a first one-way clutch between the first component and the third component; and
a second one-way clutch between the first component and the second component;
the second component includes a cup-shaped member having a disc-shaped member, having a radially inner end and a radially outer end, the radially inner end closer to the second shaft rotational axis wherein the radially inner end of the disc-shaped member connects the second component to the second shaft;
the cup-shaped member having an annular wall, the annular wall extending axially, the annular wall directly connected to the radially outer end of the disc-shaped member and spaced from the second shaft;
the first component in an opening of the cup-shaped member; and
the third component is connected to the second component, wherein the first component is between the disc-shaped member of the second component and the third component.

12. The clutch assembly of claim 11 wherein:
the first component includes at least one pocket in a first surface and at least one notch in a second surface;
the third component includes at least one notch in a side surface of the third component facing the first surface of the first component; and
the second component includes at least one pocket in a side surface of the second component facing the second surface of the first component.

13. The clutch assembly of claim 12 wherein:
the first one-way clutch includes at least one strut between the pocket in the first surface of the first component and the notch in the side surface of the third component; and
