Definitions

  • This invention relates generally to automobile door hinges and, more particularly, to low cost, zero-clearance hinges.
  • Door hinges are an important component of automotive closures. Hinges affect the door-margin accuracy, which in turn plays a large role in the quality perception of the total vehicle. It is therefore important that the pivoting joint of the hinge is manufactured in the most accurate way possible, while controlling the cost of material and manufacturing. In many cases, it is a further requirement that the door hinge be able to be dismantled in order to remove the door from the vehicle after it has been painted but before the body has been trimmed. The removal of the door allows large interior components of the automobile to be installed and eases the assembly of the door hardware.
  • United States Patent No. 5,033,163 teaches a mechanism for coupling body-side and door-side hinge members to facilitate for such door removal.
  • the hinge disclosed is typical of stamped hinges with a removable hinge pin.
  • the hinge of U.S. Patent No. 5,033,163, however, does not possess a zero-clearance pivot joint and is not perceived as a top-quality door hinge in the current marketplace.
  • U.S. Patent No. 4,542,588 discloses a hinge which does possess a zero-clearance disengageable joint. This hinge, however, is constructed of relatively costly machined, hot-rolled profile parts and is designed as a single shear joint which is weaker than the double shear joint taught in U.S. Patent No. 5,033,163.
  • a hinge assembly for mounting an automotive door to an automobile body comprising: a door side portion with first and second circular openings; a body side portion with third and fourth circular openings; said first, second, third and fourth openings adapted to be aligned about an axis; first and second bushings adapted to fit in said first and second circular openings respectively; a tube with a first end and a second end adapted to be inserted substantially through said first and second bushings and to fit snugly against said bushings; said first end of the tube comprising a flange adapted to abut said first bushing; said second end of the tube adapted to be swaged following said insertion to abut said second bushing; said tube comprising a threaded portion on its interior surface adjacent said first end; a hinge pin with head end and a leading end adapted to fasten the door side portion to the body side portion at said axis; the hinge pin comprising: (a) a head at the head end
  • the body side and door side portions are stamped.
  • the body side portion is chamfered around the third opening to contact the tapered section of the hinge pin.
  • the second threaded section of the hinge pin is adapted to be self-tapping.
  • Figure 1 is a top view of a motor vehicle door hinge showing sectional lines A-A.
  • Figures 2, 3 and 4 are sectional views along the line A-A of the hinge.
  • Steel-backed PTFE (Teflon TM) bushings 1 and 2 are inserted into circular openings 23 and 24 in the door half of the hinge 3, and a flanged tube 4 is inserted through the bushings with an interference fit.
  • An interference fit with PTFE bushings is commonly used to create a radial zero-clearance fit hinge assembly.
  • the flanged end 16 of the tube 4 abuts the bushing 1.
  • the leading end 5 of the tube is then spread open with an appropriate swage tool 18 and formed over the bushing 2. This creates an axial zero-clearance fit between the tube 4 and the door half of the hinge 3.
  • a hinge pin 7 is then inserted through the opening in body half ear 6 and tube 4 and finally past body half ear 12.
  • the hinge pin 7 is provided with a M8 x 1.25 thread 8 in the section of the pin adjacent the head 19.
  • the leading end of the pin is provided with a narrower diameter thread 9.
  • the threading 8 on the hinge pin adjacent the head corresponds with threading 10 in the tube adjacent the flanged end 16 of the tube 4.
  • the threading 9 on the pin adjacent the leading end may correspond to threading (not illustrated) in the tube and the opening 27 in body half ear 12.
  • the threading 9 at the leading end of the hinge pin may be adapted to be self-tapping to engage the tube 4 and ear 12 for a zero-clearance fit between the pin, tube and body half of the hinge.
  • the self-threading section 9 may comprise an M6 x 1.25 thread with an M8 pitch.
  • the self-tapping action of the leading end of the pin removes any free play between the body side, the pin and the swaged over tube. It is important that the pitch on both threaded portions of the pin be identical.
  • the thread 8 on the hinge pin engages the tube thread 10 first and acts as a lead screw to aid the threading of the leading end of the pin.
  • Pin portion 9 may be self-threading into an unthreaded opposite end of the tube 11 and the body half ear 12, or the end of the tube 11 and body half ear may be correspondingly threaded.
  • the hinge pin is tapered in the area adjacent the head to contact body half ear 6 which may be correspondingly chamfered.
  • the conical or tapered portion 13 of the hinge pin contacts body half ear 6, the door half of the hinge 3 and the tube 4 assembly are pulled towards the body half ear 6 to create a zero-clearance radial and axial hinge joint.
  • the body side and door side portions of the hinge are stamped rather than cast or hot-rolled.
