Benefits of technology
The patent describes a special joint design for a tube and assembly. The joint has a female portion with four segments that create unique grooves and a tubular stop. The female portion also has ball tracks for a male portion that can move within it. A cage with matching ball apertures is located between the male and female portions. Balls are placed in the apertures to allow for movement between the segments. A tube member is in direct contact with the female portion and has the same outer perimeter as it does the female portion. This design allows for precise movement between the male and female portions. Its unique features make it ideal for use in high-speed manufacturing processes and can improve the performance and efficiency of the overall assembly.
Problems solved by technology
Not only must the drive train assembly accommodate a limited amount of angular misalignment between the engine / transmission assembly and the axle assembly, but it must also accommodate a limited amount of relative axial movement.
While this process is satisfactory, is has been found to be somewhat inefficient.

Embodiment Construction
[0016]It is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions, directions or other physical characteristics relating to the embodiments disclosed are not to be considered as limiting, unless the claims expressly state otherwise.
[0017]Referring now to FIGS. 1 and 2, a slip joint 10 is depicted having a segmented female portion 12. The female portion 12 of the slip joint 10, as shown in detail in FIG. 3, is comprised of four axially extending segments 14, 16, 18, 20 of substantially equal length. It is also within the scope of the present invention for there to be more or less axially extending segments as may be required ...

Abstract
A slip joint comprising, a female portion comprised of four axially extending segments. The segments together create an outer perimeter. Each of the combined segments together form an inner surface of the female portion and each has its own ball tracks extending substantially the length of the female portion. A unitary male portion has an outer surface defined by a plurality of axially extending ball tracks. A unitary cage is located radially outward from the male portion and radially inward from the female portion. The cage has a plurality of ball apertures with balls located in the ball apertures. The balls are in contact with both the ball tracks in the male and female portions for selective movement of the male portion with respect to the female portion. A tube member is in direct radial outer contact substantially entirely along the outer perimeter of the female portion.
Description
RELATED APPLICATIONS[0001]NoneFIELD OF THE INVENTION[0002]The present invention relates to an improved structure for a rolling element spline type of slip joint for use in a vehicle.BACKGROUND OF THE INVENTION[0003]Slip joints are used for transmitting rotational force or torque between telescoping members, while accommodating relative axial movement there between. This is most commonly used in vehicle drive train systems. Drive train systems are generally used for generating power from a source and for transferring such power from the source to a driven mechanism.[0004]The typical drive train system includes a driveshaft assembly that is connected between an output shaft of an engine / transmission assembly and an input shaft of an axle assembly. The driveshaft assembling includes universal joints which provide a rotational driving connection from an output shaft of an engine / transmission assembly to an input shaft of an axle assembly, while accommodating a limited amount of angular ...
