Abstract: A method and apparatus for permanently joining two or more metallic vehicle frame components using magnetic impulse welding techniques is disclosed. In a first embodiment, an overlap joint is formed by the joinder of two individual open channel side rail sections to form a portion of a vehicle frame side rail. The first side rail section is initially formed slightly smaller in size than the second side rail section so that it may be disposed telescopically therein with clearance. An electromagnetic coil is provided for generating a magnetic field which causes the side rail sections to move toward one another at a high velocity. The high velocity impact and the large pressures cause the two side rail sections to weld or molecularly bond. Alternatively, a bracket can be joined to a side rail section in a similar manner. In a second embodiment, a pair of closed channel structural members are formed using hydroforming techniques. The end portions of two hydroformed structural members are then disposed concentrically within an electromagnetic coil. When energized, the electromagnetic coil causes the end portions to move toward one another so as to weld or molecularly bond.

Abstract: A separate type of body and frame assembly includes a frame portion and a body portion. The frame portion includes a pair of side rails, each of which has a plurality of openings formed therethrough. A plurality of cross members extend between side rails and are secured thereto. Each of the cross members has first and second ends that extend through the openings formed through the side rails. Each of the first and second ends of the cross members is formed integrally and unitarily with the cross member and has a body mount structure, such as an aperture, formed therein or otherwise provided thereon. The ends of the cross members are initially inserted through the openings formed through the side rails. Then, such ends of the cross members are secured to the side rails, such as by electromagnetic pulse welding, to form the frame portion. The body mount apertures cooperate with respective body mounts provided on the body portion to connect the body portion to the frame portion to form the vehicle body and frame assembly.

Abstract: A method for manufacturing an engine cradle for use with a vehicular body and frame assembly includes the initial step of selecting desired materials for each of four hollow members that will be secured together to form the engine cradle. The selected materials can include metallic materials, such as steel, aluminum, magnesium, and non-metallic materials, such as fiber and other composites, or any combination thereof. The selected materials are formed into desired shapes using any known method, such as by hydroforming. Then, portions of the four members are disposed in a telescoping relationship with one another, such as by providing protrusions on some of the components and disposing the ends of the other components in a telescoping relationship with such protrusions. Lastly, the telescoping portions of the members are secured together using any securement method, including laser, MIG, or electromagnetic pulse welding techniques and adhesive bonding.

Abstract: A splice joint for connecting a pair of open channel side rail sections in a vehicular body and frame assembly focuses stresses imposed thereon away from the longitudinal edges of the structural members. In a first aspect of this invention, one or both end portions of the side rail sections are formed having an offset. The end portions of the side rail sections overlap one another and are secured together in any conventional manner, such as by welding. Preferably, the welds are made in such a manner that they terminate prior to reaching any of the longitudinally extending edges of the side rail sections. In a second aspect of this invention, the portions of the side rail sections are butt welded together. A support bracket is secured to the side rail sections in any conventional manner, such as by welding. Again, the welds are preferably made in such a manner as to terminate prior to reaching any of the longitudinally extending edges of the side rail sections.

Abstract: A method for connecting a ball and socket joint to a control arm in a vehicle suspension system includes providing the ball and socket joint with a socket portion having a circumferential flange. The ball and socket joint is initially aligned with an opening formed through an outer portion of the control arm. Then, the ball and socket joint is moved upwardly such that the socket portion is received within the opening. The socket portion defines an outer diameter that is preferably slightly smaller than an inner diameter defined by the opening formed through the outer portion of the lower control arm. However, the flange defines an outer diameter that is preferably larger than an inner diameter defined by that opening. Thus, the engagement of the flange with the lower surface of the outer portion positively positions the ball and socket joint relative to the lower control arm. Then, one or more regions of the socket portion of the ball and socket joint are deformed into engagement with the upper surface of the outer portion of the lower control arm. The deformed regions cooperate with the flange to trap the corresponding portions of the outer portion of the lower control arm therebetween. As a result, the ball and socket joint is securely connected to the lower control arm.

Abstract: A method for manufacturing a driveshaft for use in a vehicle drive train system that is axially collapsible in the event of a collision to absorb energy. A workpiece, such as a hollow cylindrical tube, is deformed by hydroforming to provide an axial collapse initiation zone. The axial collapse initiation zone can be defined by a plurality of axially extending undulations or corrugations that are formed in a central portion of the tube. The axial collapse initiation zone is designed to accommodate the transmission of torque through the driveshaft without any deformation under normal operating conditions. However, if a relatively large axial force is applied to the front and rear end portions of the driveshaft, the axial collapse initiation zone is designed to allow relative axial movement to occur between the front and rear end portions of the driveshaft. Such collapsing functions to absorb energy during a collision, thereby providing additional safety to the occupants of the vehicle. If desired, the driveshaft can be hydroformed to include integral yoke portions on the ends thereof.

Abstract: A method of joining two vehicle suspension components made from the same or dissimilar materials includes providing a first suspension component, and providing a second suspension component made from a material which is same/dissimilar to the material used to make the first suspension component, where one of the first and second suspension components is a metallic component made of a metallic material. A portion of one of the first and second suspension components is positioned within a portion of the other of the suspension components in an overlapping manner, thereby forming an overlapping portion. A metallic band may be disposed around the overlapping portion. An inductor is positioned around the overlapping portion. The inductor is energized to generate a magnetic field for collapsing at least one of the overlapping portion and the metallic band at a velocity sufficient to magnetic pulse weld the components to each other, thereby securing the first and second suspension components together.
