A contra-bevel driven control mechanism repositions a control surface in a fluid environment such as an aerodynamic or hydrodynamic environment. This involves mechanically coupling an airfoil and a control surface. The control surface may pivot about a spanwise axis between upwardly deflected and downwardly deflected positions. A forward beveled rotor mounted to the airfoil and an aft beveled rotor mounted to the control surface counter rotate. The forward beveled rotor rotates about a forward chordwise axis within the airfoil while the aft beveled rotor rotates about an aft chordwise axis within the control surface. The angular rotation between the forward beveled rotor and the aft beveled rotor deflects the aft beveled rotor and the aft chordwise axis within the control surface. Additionally, this method allows the control surface to be deflected with maximum mechanical advantage when the control surface is fully deflected.

A shatterproof pressure vessel for storing pressurized gas used in a hybrid-type air bag inflator until the gas is expanded for inflating an air bag, is formed of a thin wall, metal tube made by extruding a metal ring axially through a constricted die orifice to provide an elongated tube. The extrusion generally aligns the metal grain structure into a generally elongated, axially oriented fiber-like configuration. End closures are secured to the opposite ends of the tube to form the sealed pressure vessel. One end closure is openable to receive an ejection from a solid propellant means which is actuated for heating and expanding the gas within the vessel. The opposite end closure is openable to release the expanding gas into a vehicle occupant restraining air bag for inflation of the bag. In the event that the gas pressure within the tube exceed the burst strength of the tube wall, the wall will split along its axial longitudinal direction to provide an opening for relieving the excess pressure, rather than shattering into fragments.

An elongated, rod-like rack for use in an automotive-type steering gear assembly and like mechanisms, is formed of an elongated extruded tube divided lengthwise into a substantially solid rack portion and a substantially hollow, link portion. Transversely extending teeth are broached on the rack portion for engagement with a drive pinion means and the like for transmitting power through the rack. The rack is formed by positioning a tubular blank within an open ended extrusion die having an extrusion throat and pushing the tubular blank through the throat for extruding the material longitudinally and collapsing radially inwardly to form a substantially solid, elongated rack portion continuing the pushing the blank with the mandrel within the die throat to extrude a thin wall length, which forms the hollow, integral link part of the rack. The trailing end may be terminated in an inwardly extending, thick wall portion suitable for forming threads thereon.

Light weight drive shaft

A method for forming a lightweight flanged axle shaft particularly for use within automotive vehicles for transmitting power from a power source, such as the differential, to a driven wheel. The method includes extruding a tubular blank through a die throat by pushing the blank through the die throat and causing the blank to collapse inwardly around a mandrel-like member located within the die throat to thereby form an elongated, thin wall, hollow tube. A flange member is separately forged out of metal with a disk-like flange and central cup-shaped hub whose free edge is of approximately the same size and thickness as the end of the shaft. The flange hub and the shaft end are welded together, face to face, by engaging the two and rapidly spinning one relative to the other to generate sufficient heat and to butt the adjacent faces to fuse them together upon discontinuance of the rotation. This produces a long, hollow, thin wall, lightweight shaft having one end closed by the flange extending laterally thereof. The flange hub and shaft end are integrated to form a one piece unit. The opposite end of the shaft is configured, such as with spline teeth, for fastening one end of the shaft to a drive or driven member while the flange at the opposite end of the shaft is secured to the opposite drive or driven member.

A lightweight driveshaft is extruded from a tubular metal blank into an elongated tube having an integral center and opposite end sections. The center section has a thin wall while the end sections have a thick wall. The shaft is formed by inserting a tubular blank within a tubular die having a restricted die throat through which the blank is extruded. Punches are inserted into the tubular blank to extrude the shaft.

A large drive shaft is formed of an extruded metal, thin wall tube, having integral, annular, inwardly thickened, ring-like areas at its opposite ends. A number of radially inwardly directed ribs are integrally formed upon the inner wall surface of the tube wall and extend the full length of the tube between the ring-like areas. The ribs are spaced apart from each other and, preferably, area of a height which is less than the thickness of the thin wall. The opposite ends of the shaft are provided with conventional connecting means for connecting the shaft to a drive device and a driven device transmitting power therebetween.

Elongated, lightweight rack

An elongated, rod-like rack for use in an automotive-type steering gear assembly and like mechanisms, is formed of an elongated extruded tube divided lengthwise into a substantially solid rack portion and a substantially hollow, link portion. Transversely extending teeth are broached on the rack portion for engagement with a drive pinion and the like for transmitting power through the rack. The rack is formed by positioning a tubular blank within an open ended extrusion die having an extrusion throat and partially pushing the tubular blank through the throat for extruding the material longitudinally and collapsing radially inwardly top form a substantially solid, elongated rack portion. Then, extrusion is continued with a punch having a mandrel arranged within the blank and within the die throat for extruding a thin wall length, forming the hollow, integral link part of the rack. The trailing end may be terminated in an inwardly extending, thick wall portion suitable for forming threads thereon. The elongated rack part has a fine, axially extending opening along its length resulting from a space left when the material is inwardly collapsed in the die throat for providing a communication passageway.

A metal tube, such as a valve body sleeve, is cold extruded to form full length and partial length longitudinal channels in its interior wall surface. The channeled tube is formed by extruding a metal, tubular blank, through an open ended die having an extrusion die throat at one end. A punch is inserted in the die and bears against an end of the blank for pushing the blank longitudinally through the die throat. The punch has an extension, having a leading edge section and a trailing edge section that pass through the blank. Longitudinally extending teeth are formed on the two sections, with some of the teeth being continuously longitudinally aligned and others being located only on the trailing section. Initially, the leading section is arranged within the die throat and the leading end portion of the blank is extruded through the die throat, around the extension leading section to form channels therein. Then, the punch trailing section is within the die throat as the punch continuously pushes the blank through the die throat so as to continue the formation of the channels started by the leading sections while simultaneously forming channels in the intermediate portion of the blank. Then, the punch is removed, a new blank is inserted against the first blank, and the punch is replaced for pushing the second blank, and thereby, the first blank through the die throat while the punch leading section is positioned within the die throat so as to continue the formation of full length channels while discontinuing the formation of partial channels within the intermediate portion of the blank.

A process for cold forming integral spindle-axle tubes includes placing a tubular blank within an open ended die having an extrusion die throat, and pushing the blank through the die throat with a punch. The punch is formed with a ram portion that applies pressure to the blank for moving it axially through the throat. The punch also has an extension closely fitted within the blank so that as the punch pushes the tube axially, the blank is extruded between the die throat and the extension to form a thin wall tube. After the blank is partially extruded, the punch is removed and a second blank is inserted. This second blank is then located between the punch ram portion and the trailing end of the first blank so that further movement of the punch causes the second blank to push the first blank through the die throat. At that time, a second punch extension, of smaller diameter than the first one, is arranged within the throat so that an inwardly thickened ring-like annular section is extruded within the extruded tube, at a distance from the trailing end of the tube. The die movement continues until the first extension is aligned within the throat and the trailing end portion of the extruded tube is completed. Thereafter, the steps are repeated to form additional extruded tubes. Each extruded tube has its trailing end portion and thickened ring section swaged radially inwardly first, until its outside diameter is less than the outside diameter of the tube, and secondly, until the inside diameter of the thinner wall trailing end portion is formed to the same internal diameter as that of the thickened section to thereby provide the integral spindle-axle tube.

Process for forming integral spindle-axle tubes

An improved method for manufacturing a steering knuckle and spindle unit for a heavy duty vehicle, such as a truck, including forming the spindle, separately forming the knuckle, and finally welding the knuckle and spindle together to form an integral unit. The spindle is a hollow elongated metal tube preferably cold formed. The knuckle is formed by forging and a bore is machined or pierced in the knuckle to be aligned with the hollow portion of the spindle. The knuckle and spindle are then welded together such as by spin or inertia or electron beam welding to form an integral unit.
