  • Patent number: 6134779
    Abstract: An improved high performance aluminum connecting rod and a method for manufacturing such a connecting rod are disclosed, the connecting rod being capable of carrying particularly high compressive loads with a substantially reduced deformation resulting from such high compressive loads. In the preferred embodiment, the connecting rod of the present invention is made of an extruded bar stock forging made of an aluminum alloy material which is forged and machined to make the connecting rod. The connecting rod of the present invention has a substantially increased compressive yield strength as well as a substantially increased tensile yield strength. This increase in the compressive yield strength of the connecting rod of the present invention effectively prevents bending of the connecting rod beam, elongation of the wrist pin bore, and a marked deterioration in the roundness of the bearing housing bore.

  • Patent number: 6116113
    Abstract: A composite link includes a fiberglass body. The body is formed by coating glass fibers with a liquid resin and winding the fibers around a plurality of end pieces or bushings. The end pieces have transition sections for smoothly changing the shape of the composite link and the path of the fibers. The fibers are wound in two layers, a first extending longitudinally of the body and the second transversely and around the first. A shield layer is placed over the fiberglass body.

  • Patent number: 6109164
    Abstract: A push rod of a vacuum booster includes an inner rod section, a pipe-shaped outer rod section which is slidably fitted over an outer periphery of a rear portion of the inner rod section and connected to a brake pedal, and a buffer member made of a synthetic resin and fitted over the outer periphery of the inner rod section in front of the outer rod section. Usually, an end face of the outer rod section is retained in a position in which it abuts against a projection of the inner rod section. When an axial compressing force is applied to the push rod upon a collision of an automobile, the end face of the outer rod section slides forwards over and past the projection, while buckling the buffer member. Thus, the pushing-up of the brake pedal toward a vehicle compartment due to the retreating movement of a master cylinder is prevented, and the load applied to a driver's foot is alleviated.

    Abstract: A push rod ball has an exteriorly oriented wear surface surrounding an interior core. The interior core is composed of a steel or steel alloy containing between about 0.1% and about 0.2% by weight carbon. A hardened case layer is of an essentially uniform depth is located between the exterior surface and the inner core. The push rod ball has a cylindrical throughbore transiting its diameter. A central through bore diametrically bisects the spherical metal body forming the push rod ball. The bore is bounded by a cylindrical inner wall composed of metal of the central core and the hardened case regions of the metal body. The push rod ball can be positioned on a suitable push rod shaft to provide a push rod assembly in which the weld region connecting shaft to ball extends through the hardened case region into the central core of the push rod ball.

    Abstract: A light-weight bearing cap for attaching a connecting rod to a journal of a crankshaft pin has two longitudinally extending shoulders separated by an arcuate span conforming to the shape of the journal The shoulders are adapted to receive fasteners which connect mating surfaces of the connecting rod to those of the bearing cap. Mass is conserved by ensuring that the inner and outer arcuate surfaces are shaped as arcs of non-concentric circles such that the maximum thickness of the span occurs at the bisecting points of the respective arcs and the minimum thickness of the span occurs in the region between the shoulders and the maximum thickness. The thickness where the machined surface on the shoulder is located is greater than in the region between the shoulder and the region of maximum thickness.

    Abstract: Disclosed is a manufacturing process of a sintered connecting rod assembly comprising a first member with a projection and a second member with a concavity in which the first member and the second member are mated with each other by engaging the projection with the concavity. A powdered raw material is compacted into a first compact and a second compact for the first and second members, wherein the projection of the first compact has a width slightly larger than the width of the concavity of the second compact. Then the projection of the first compact is engaged with the concavity of the second compact to mate the first compact with the second compact, thereby the projection and the concavity are tightly pressed against each other. After sintering the mated first and second compacts, they are forced to release the projection from the concavity. The die for compacting the raw material has a whole cavity and a removable core for dividing the whole cavity into two cavities.

    Abstract: A link, and assembly and instrument using same, for transmitting actuating forces from an actuating member to a work member. The link includes a link body having a distal end and a proximal end. The distal end of the link body is movably interconnected with the work member by a distal interconnection element such as an arcuate groove-and-flange assembly, and is interconnected at its proximal end to an actuating member by a proximal pivotal interconnection element. The proximal element transmits a first actuating force from the actuating member to the work member. A shoulder, disposed on the link body preferably between the distal and proximal elements for interconnecting, engages the actuating member when a second, greater actuating force is applied to the actuating member in a direction opposite to that of the first actuating force. The greater force is thereby transmitted fully to the work member. The link assembly preferably includes a spacer member to assist positioning of the actuating member.

  • Patent number: 5456137
    Abstract: A method for forming a shaft with protrusions applies vertical pressure to the shaft to deformably displace material from the shaft to form one or more protrusions. The protrusions are angularly spaced on and circumferentially aligned relative to the peripheral surface of the shaft. The shaft may be of any diameter, but typically a diameter of three-eighths of an inch, with the protrusions forming a larger diameter of typically one-half of an inch.

  • Patent number: 5435286
    Abstract: A ball link assembly in which a link member has a semi-spherical cavity formed in each end for rotatably receiving a respective complementary spherical bearing ball formed, preferably, of a ceramic material. Each ball is freely retained by a ball retainer formed of spring steel, the ball retainer extending just over the equator of the ball and mounting to the link by a sideways snap-on action. In one form, the link is designed to accommodate an existing link retainer which is fixed internally of the injector assembly, while in a second form the link assembly is retained by a link retainer which is externally tethered.

  • Patent number: 5429014
    Abstract: An adjustable, pre-set, threaded and torqued pedal rod has a shaft part and a head part which are selectively adjusted and assembled with the use of screw threads to a pre-selected longitudinal mean dimension and then securely crimped to lock the parts together so that the two parts cannot be separated without total destruction. Screw threads of different size are disposed on two separate tiers to afford torque locking.

  • Patent number: 5413013
    Abstract: A sand molding machine comprises an elongated tie rod with a removable bearing sleeve portion at its distal end. The distal end of the rod where the sleeve is attached has a reduced diameter end spindle portion with multiple stepped support sections on its outer surface. The sleeve is of generally hollow cylindrical configuration and fits over the spindle end portion of the rod. The sleeve has an outward cylindrical bearing surface, and an inward surface with stepped support sections corresponding to and contacting the outside support sections on the rod when the sleeve is attached. The respective supporting sections on the rod and the sleeve provide a strong tight attachment of the sleeve to the rod without requiring excessive force in order to attach and/or remove the bearing from the rod.
