Abstract

A joint assembly and clutch assembly for use in a vehicle. The joint assembly includes a first joint member that is drivingly connected to a second joint member by using one or more third joint members. A first shaft is drivingly connected to the first joint member. The clutch assembly includes a first clutch member, a second clutch member, and an actuation assembly that is operably configures to selectively drive the second clutch member into engagement with the first clutch member of the clutch assembly. The actuation assembly utilizes an amount of rotational force that is transmitted from the first shaft in order to transition the second clutch member into engagement with the first clutch member. At least a portion of a second shaft is drivingly connected to the second clutch member.

First claim

What is claimed is:

1. A clutch assembly, comprising:
a joint assembly comprising a first joint member drivingly connected to a second joint member by one or more third joint members;
a first shaft drivingly connected to said first joint member;
a first clutch member, wherein said first clutch member is integrally formed as part of said second joint member of said joint assembly;
a second clutch member that is selectively engagable with said first clutch member;
a second shaft drivingly connected to said second clutch member;
an actuation assembly operably configured to selectively transition said clutch assembly between a disengaged position and an engaged position;
a ball and ramp assembly having a first plate, a second plate, and one or more balls interposed between said first plate and said second plate;
wherein said first plate of said ball and ramp assembly is operably configured in order to transmit an amount of force onto said second clutch member thereby transitioning said clutch assembly from a disengaged position to an engaged position; and
wherein said actuation assembly utilizes an amount of rotational force transmitted from said first shaft or said second shaft in order to transition said second clutch member into engagement with said first clutch member.

2. The clutch assembly of claim 1 , wherein said joint assembly is a constant velocity joint assembly, a CV joint assembly, a homokinetic joint assembly, a universal joint assembly, a U-joint, a Cardan joint assembly, a Spicer joint assembly or a Hooke's joint assembly.

3. The clutch assembly of claim 1 , further comprising a housing having a first end portion, a second end portion, an inner surface and an outer surface defining a hollow portion therein;
wherein at least a portion of said joint assembly, said clutch assembly and/or said actuation assembly is disposed within at least a portion of said hollow portion of said housing.

4. The clutch assembly of claim 3 , wherein said inner surface of said housing has one or more housing grooves therein to receive an amount of lubricating fluid therein.

5. The clutch assembly of claim 1 , wherein said first clutch member has a wall portion;
wherein at least a portion of a first side of said wall portion of said first clutch member provides a reaction surface for at least a portion of said second clutch member;
wherein with said at least a portion of said second clutch member is engaged with at least a portion of said first side of said wall portion of said first clutch member said clutch assembly is in said engaged position; and
wherein when said at least a portion of said second clutch member is not engaged with said at least a portion of said first side of said wall portion of said first clutch member said clutch assembly is in said disengaged position.

6. The clutch assembly of claim 1 , wherein one or more receiving portions extend inward into said first clutch member from at least a portion of a first side of a wall portion of said first clutch member;
wherein said one or more receiving portions in said wall portion of said first clutch member are of a size and shape to receive and/or retain at least a portion of one or more first engagement portions extending outward from at least a portion of a first side of an increased diameter portion of said second clutch member;
wherein when said at least a portion of said one or more first engagement portions of said second clutch member are engaged with at least a portion of said one or more receiving portions of said first clutch member said clutch assembly is in said engaged position; and
wherein when said one or more first engagement portions of said second clutch member are not engaged with said one or more receiving portions of said first clutch member, said clutch assembly is in said disengaged position.

7. The clutch assembly of claim 6 , wherein said one or more receiving portions in said wall portion of said first clutch member have one or more first sloped surfaces and/or one or more second sloped surfaces terminating in a bottom portion;
wherein said one or more first engagement portions of said second clutch member have one or more first sloped surfaces and/or one or more second sloped surfaces terminating in an outboard surface; and
wherein at least a portion of said one or more first sloped surfaces, said one or more second sloped surfaces and/or said outboard surface of said second clutch member are selectively engagable with at least a portion of said one or more first sloped surfaces, said one or more second sloped surfaces and/or said bottom portion of said first clutch member.

8. The clutch assembly of claim 1 , wherein said second clutch member further comprises one or more slots extending from an outermost surface of said second clutch member toward an inner surface of said second clutch member; and
wherein said one or more slots in said second clutch member allow at least a portion of said second clutch member to be elastically deformed when said clutch assembly is in said engaged position.

9. The clutch assembly of claim 1 , further comprising one or more first biasing members; and
wherein said one or more first biasing members aid in transitioning said clutch assembly between said engaged position and said disengaged position by driving said second clutch member into or out of engagement with said first clutch member.

10. The clutch assembly of claim 1 , further comprising one or more coatings; and
wherein said one or more coatings are disposed on at least a portion of one or more components of said clutch assembly and/or one or more components of said actuation assembly.

11. The clutch assembly of claim 10 , wherein said one or more coatings are heat resistant and/or have a high coefficient of dynamic friction.

12. The clutch assembly of claim 1 , further comprising one or more second biasing members; and
wherein said one or more second biasing members aid in transitioning said clutch assembly between said engaged position and said disengaged position.

13. The clutch assembly of claim 1 , wherein said actuation assembly further comprises an electro-magnetic coil, a first engagement member and a second engagement member;
wherein an inner surface of said first engagement member is operably configured in order to rotate said second plate of said ball and ramp assembly when a first engagement portion of said first engagement member is engaged with a second engagement portion of said second engagement member of said actuation assembly; and
wherein said electro-magnetic coil is operably configured in order to selectively engage said first engagement portion with said second engagement portion.

14. The clutch assembly of claim 13 , wherein said first engagement member is integrally formed as part of said second plate of said ball and ramp assembly.

15. The clutch assembly of claim 13 , wherein said second engagement member is integrally formed as part of a housing of said electro-magnetic coil.

16. The clutch assembly of claim 13 , wherein said actuation assembly further comprises an armature; and
wherein said electro-magnetic coil is operably configured to drive said armature toward said first engagement member and selectively engage said first engagement portion with said second engagement portion thereby selectively transitioning said clutch assembly between said disengaged position and said engaged position.

17. The clutch assembly of claim 1 , wherein said actuation assembly further comprises one or more first friction plates, one or more second friction plates, and
