Abstract

A drive train connector assembly includes a first connecting structure and a second connecting structure. The first connecting structure has an attachment protrusion with first and second edges. The first edge extends in a first direction. The second edge extends in a second direction. Both directions are perpendicular to the rotational axis. The first and second directions define a first acute angle therebetween. The second connecting structure defines recessed area. The attachment protrusion fits into the recessed area. The recessed area defines third and fourth edges. The third edge extends in a third direction and the fourth edge extends in a fourth direction. The third direction and the fourth direction define a second acute angle. With the attachment protrusion installed within the recessed area the first and third edges are parallel to one another and the second and fourth edges are parallel to one another.

First claim

What is claimed is:

1. A drive train connector assembly, comprising
a first connecting structure dimensioned and designed for rotation about a rotational axis and having attachment protrusion that defines a first edge and a second edge, the first edge extending in a first direction perpendicular to the rotational axis, the second edge extending in a second direction perpendicular to the rotational axis, the second direction and the first direction defining a first acute angle greater than 2 degrees therebetween;
a second connecting structure defining recessed area dimensioned such that the attachment protrusion is fitted into the recessed area, the recessed area defining a third edge and a fourth edge, the third edge extending in a third direction perpendicular to the rotational axis, the fourth edge extending in a fourth direction, the third direction and the fourth direction defining a second acute angle greater than 2 degrees therebetween such that with the attachment protrusion installed within the recessed area the first and third edges are parallel to one another and the second and fourth edges are parallel to one another; and
a cover fitted to and encircling one of the first connecting structure and the second connecting structure, the cover being slid between an install/release orientation and a locking orientation such that in the install/release orientation the second connecting structure is movable relative to the first connecting structure, and in the locking orientation the first connecting structure and the second connecting structure are non-releasably fixed to one another by the cover.

2. The drive train connector assembly according to claim 1 , wherein
the attachment protrusion of the first connecting structure and the recessed area of the second connecting structure define mating dovetail-like shapes.

3. The drive train connector assembly according to claim 1 , further comprising
a rotary power providing member fixedly attached to the first connecting structure; and
a rotary power receiving member fixedly attached to the second connecting structure.

4. The drive train connector assembly according to claim 3 , further comprising
the rotary power providing member is an automotive drive shaft, and
the rotary power receiving member is an automotive differential assembly.

5. The drive train connector assembly according to claim 3 , further comprising
the rotary power providing member is an automotive transmission, and
the rotary power receiving member is a constant velocity joint.

6. The drive train connector assembly according to claim 3 , further comprising
the rotary power providing member is a constant velocity joint, and
the rotary power receiving member is wheel axle.

7. The drive train connector assembly according to claim 1 , wherein
the cover is retained in the locking orientation by a locking portion defined by at least one of the first connecting structure and the second connecting structure.

8. The drive train connector assembly according to claim 7 , wherein
the locking portion is a spring loaded detent ball device installed to the second connecting structure.

9. The drive train connector assembly according to claim 7 , wherein
the locking portion is a locking ring installed an annular recess of the second connecting structure.

10. The drive train connector assembly according to claim 7 , wherein
the locking portion is a crimped area of the cover deformed to engage an annular recess of the second connecting structure.

11. A drive train connector assembly, comprising
a rotary power providing member configured to rotate about a rotational axis;
a rotary power receiving member configured to rotate about the rotational axis;
a first connecting structure configured to rotate about a rotational axis, the first connecting structure being connected to one of the rotary power providing member and the rotary power receiving member and having a dove-tail shaped protrusion, that has a first end at one side of the rotational axis having a first width and a second end on a second side of the rotational axis having a second width with the first width being greater than the second width;
a second connecting structure configured to rotate about the rotational axis when connected to the first connecting structure, the second connecting structure being connected to the other of the rotary power providing member and the rotary power receiving member and having a dove-tail shaped recessed are dimensioned and shaped to receive the dove-tail shaped protrusion; and
a cover fitted to and encircling one of the first connecting structure and the second connecting structure, the cover is slid between an install/release orientation and a locking orientation such that in the install/release orientation the second connecting structure is movable relative to the first connecting structure, and in the locking orientation the first connecting structure and the second connecting structure are non-releasably fixed to one another by the cover.

12. The drive train connector assembly according to claim 11 , wherein
the dove-tail shaped protrusion and the dove-tail shaped recessed area are shaped and dimensioned with corresponding drag angles, the drag angles being acute angles.

13. The drive train connector assembly according to claim 11 , further comprising
the rotary power providing member is an automotive drive shaft, and
the rotary power receiving member is an automotive differential assembly.

14. The drive train connector assembly according to claim 11 , further comprising
one of the rotary power providing member and the rotary power receiving member is a constant velocity joint.

15. The drive train connector assembly according to claim 11 , wherein
the cover is retained in the locking orientation by a locking portion defined by at least one of the first connecting structure and the second connecting structure.

16. The drive train connector assembly according to claim 11 , wherein
the locking portion is a spring loaded detent ball device installed to the first connecting structure.

17. The drive train connector assembly according to claim 11 , wherein
the locking portion is a locking ring installed an annular recess of the second connecting structure.

18. The drive train connector assembly according to claim 11 , wherein
the locking portion is a crimped area of the cover deformed to engage an annular recess of the second connecting structure.

19. The drive train connector assembly according to claim 11 , wherein
the attachment protrusion of the first connecting structure defines a first edge and a second edge, the first edge extending in a first direction perpendicular to the rotational axis, the second edge extending in a second direction perpendicular to the rotational axis, the second direction and the first direction defining a first acute angle greater than 2 degrees therebetween; and
the recessed area of the second connecting structure being dimensioned such that the attachment protrusion is fitted into the recessed area, the recessed area defining a third edge and a fourth edge, the third edge extending in a third direction perpendicular to the rotational axis, the fourth edge extending in a fourth direction, the third direction and the fourth direction defining a second acute angle greater than 2 degrees therebetween.
