- Fig. 1 illustrates a frame assembly 10 for a motor vehicle constructed according to an embodiment of the present invention.
- the frame assembly 10 shows a frame assembly in the form of, for example, a side rail member of a space frame for an automobile.
- the frame assembly 10 can be used for any appropriate tubular member needing added support from an interior support element such as a support tube or an element to provide guidance and support for a fastener extending through a tubular member.
- the frame member assembly 10 may be incorporated into any suitable section of the vehicle frame, and the frame member assembly 10 may be utilized on any suitable motor vehicle.
- the frame member assembly 10 includes a longitudinally extending tubular frame member 12 and a support tube 14 positioned within the hollow cavity 16 of the tubular frame member 12. As will be discussed in greater detail below, the support tube 14 is secured within the frame member 12 by pre-formed indents 18, 20 provided in opposing walls of the frame member 12.
- the tubular frame member 12 is formed from first and second generally U-shaped member portions 22, 24 that are rigidly connected to one another, e.g., by welding.
- each member portion 22, 24 forms a longitudinal half of the completed tubular frame member 12.
- Each member portion 22, 24 is formed separately from an elongated piece of sheet metal, e.g., high strength steel.
- the sheet metal is bent into the desired shape of each member portion 22, 24 by a stamping operation. However, the sheet metal may be bent into the desired shape of each member portion 22, 24 in any other suitable manner.
- One piece of sheet metal is bent into a generally U-shaped configuration to provide the member portion 22 with opposing side walls 26, 28 and a central wall 30 extending between the side walls 26, 28.
- another piece of sheet metal is bent into a generally U-shaped configuration to provide the member portion 24 with opposing side walls 32, 34 and a central wall 36 extending between the side walls 32, 34.
- the side walls 26, 28 are substantially perpendicular to the central wall 30, and the side walls 32, 34 are substantially perpendicular to the central wall 36.
- the central wall 30 of the first member portion 22 is longer than the central wall 36 of the second member portion 24. This arrangement allows the ends 38, 40 of the side walls 26, 28 to overlap and engage the ends 42, 44 of the side walls 32, 34 when the member portions 22, 24 are engaged with one another to form the tubular frame member 12.
- the engaged ends 38, 40, 42, 44 can then be rigidly connected to one another, e.g., by welding together the engaged ends 38, 40, 42, 44 with welding seams that extend the length of the frame member 12.
- An aperture 46 is provided in a central section of the central wall 30 of the member portion 22, and an aperture 48 is provided in a central section of the central wall 36 of the member portion 24.
- the apertures 46, 48 have a substantially circular configuration, and are axially aligned with one another when the member portions 22, 24 are connected to one another to form the frame member 12.
- the apertures 46, 48 may have any other suitable configuration, e.g., non-circular.
- the apertures may be formed for receiving a fastener 100 that extends through the assembly 10, e.g., to attach another element to the assembly 10.
- the apertures 46, 48 in the member portions 22, 24 may be pierced in a piercing operation that is an integral part of the stamping operation. However, the apertures 46, 48 may be formed in a piercing operation that is separate from the stamping operation, e.g., laser cut.
- the central wall 30 of the member portion 22 includes indent 18, and the central wall 36 of the member portion 24 includes indent 20.
- the indents 18, 20 surround respective apertures 46, 48, and cooperate to secure the support tube 14 between the member portions 22, 24 and adjacent the apertures 46, 48.
- the indents 18, 20 are structured such that they have a shape that substantially corresponds to a shape of the support tube 14.
- the support tube 14 is tubular and includes a cylindrical exterior surface 50, a cylindrical interior surface 52, and substantially flat end surfaces 54, 56.
- the indents 18, 20 are in the form of annular protrusions.
- the support tube 14 is secured between the member portions 22, 24 such that it extends in surrounding relation to the apertures 46, 48 with the open ends of the support tube 14 axially aligned with the apertures 46, 48.
- the indents 18, 20 abut the exterior surface 50 of the support tube 14 to align the support tube 14 with the apertures 46, 48, and maintain the support tube 14 in place.
- the inside diameter of the support tube 14 is greater than the diameter of the apertures 46, 48, and the outside diameter of the support tube 14 is less than the inner diameter of the indents 18, 20.
- the annular-shaped indents 18, 20 extend coaxially around the respective aperture 46, 48.
- the indents 18, 20 each have an inclined inner surface 58 and an inclined outer surface 60. The inner edge of the inner surface 58 is spaced from the edge of the respective aperture 46, 48 to define a gap therebetween.
- the gaps between the indents 18, 20 and the respective apertures 46, 48 define substantially flat support surfaces 62, 64.
- the end surfaces 54, 56 of the support tube 14 engage against respective support surfaces 62, 64, and the exterior surface 50 of the support tube 14 is engaged with the inner surface 58 of respective indents 18, 20.
- the inner edge of the inner surface 58 engages the exterior surface 50 of the support tube 14.
- the interior surface 52 of the support tube 14 is adjacent to the outer edge of the inclined outer surface 60.
- the indents 18, 20 may have any suitable arrangement to the trap and position the support tube 14 between the member portions 22, 24, and adjacent to the apertures 46, 48.
- the member portions 22, 24 trap the support tube 14 between the member portions 22, 24 without the use of any post welding or nail-piercing operations.
- the annular-shaped indents 18, 20 are only exemplary, and are not intended to be limiting.
- the indents 18, 20 may be in the form of a series of spaced apart protrusions 200 that extend annularly around the respective aperture 46, 48.
- the indents 18, 20 may have any other suitable configuration, e.g., non-circular plan-form configuration, in order to trap any suitably shaped support tube. That is, the support tube may have a non-circular cross-sectional configuration and the indents may be structured to provide surfaces that secure the support tube in place such that the support tube extends in surrounding relation to apertures formed in the member portions 22, 24.
- the indents 18, 20 in the member portions 22, 24 may be formed during the stamping operation that forms the walls of the member portions 22, 24. However, the indents 18, 20 may be formed in any other suitable manner.
- the support tube 14 functions as a fastener guide by guiding a fastener
- the support tube 14 serves as reinforcement to the frame member 12 at such location.
- the support tube 14 can accept fasteners such as fastener 100 therethrough without the risk of collapsing the frame member
- Figs. 3-5 illustrate the method for forming the frame member assembly 10 in accordance with an embodiment of the invention.
- the member portions 22, 24 are pre-formed by a stamping operation wherein the member portions 22, 24 are provided with apertures 46, 48 and indents 18, 20 surrounding the apertures 46, 48, respectively.
- the first member portion 22 is initially engaged with a fixture assembly 70 such that a fixture pin 72 of the fixture assembly 70 protrudes through the aperture 46 in the first member portion 22.
- the support tube 14 is loaded over the fixture pin 72 so that the end surface 54 of the support tube 14 engages the support surface 62 of the first member portion 22, and the exterior surface 50 of the support tube 14 engages the indent 18.
- the inner surface 58 of the indent 18 is angled, which helps to guide the support tube 14 into its operative position wherein it extends coaxially around the aperture 46 and extends coaxially within the indent 18.
- the second member portion 24 is engaged with the first member portion 22 such that the ends 42, 44 of the second member portion 24 fit inside the ends 38, 40 of the first member portion 22.
- This action moves the ends 38, 40, 42, 44 adjacent to one another, and into overlapping engagement.
- the end surface 56 of the support tube 14 engages the support surface 64 of the second member portion 24, and the exterior surface 50 of the support tube 14 engages the indent 20. This secures the support tube 14 between the member portions 22, 24.
- the overlapping ends 38, 40, 42, 44 are rigidly secured to one another by welding so that the support tube 14 is rigidly secured within the frame member 12 without further operations or processing.
- the completed member assembly 10 may be removed from the fixture assembly 70 for use in the vehicle frame.
- the frame member 12 illustrated is only exemplary, and the transverse cross-sectional configuration may be suitably varied to meet certain requirements for a particular vehicle. Regardless of the frame member configuration, opposing walls of the frame member may be pre-formed with indents as described above to secure a support tube within the hollow cavity of the frame member.
