    摘要： A piston assembly and method of construction thereof for an internal combustion engine are provided. The assembly includes a piston head having an upper combustion wall with an undercrown surface and a ring belt region. The piston head has a floor with an upper surface and a bottom surface. The floor is spaced beneath the upper combustion wall in radial alignment with the ring belt region. A substantially enclosed, annular cooling gallery is bounded by the undercrown surface and the floor. A pair of pin bores depends directly from the floor of the cooling gallery. The assembly further includes a pin having ends configured for oscillating receipt in the pin bores. A pin bearing surface extends within the pin bores and between the pin bores in the lower surface of the floor. The assembly includes a connecting rod with an end fixed to the pin for conjoint oscillation therewith.

    摘要： A piston and piston rod subassembly for use with a hydraulic damper is disclosed. The piston is formed from a substantially flat blank having a pattern of bendable tabs provided along a first edge. A bendable skirt is provided along a second edge of the blank. After the blank is formed into a cylindrical body, the tabs are crimped onto a flanged end of a piston rod. A valve assembly can be retained in the cylindrical body by crimping the skirt over the valve assembly.

    摘要： The invention provides a hollow core filled piston including core retaining means for mechanically interlocking and retaining a core of filler material within the piston against angular and axial displacement. The piston includes a hollow skirt portion defining a stepped-bore cavity, and retaining means for retaining a core of filler material within the cavity comprising a plurality of annular projections formed from the shoulder between the stepped bores. The invention further provides a tool for cutting and displacing segments of the shoulder to form the annular projections.

    摘要： A method of manufacturing a connecting rod assembly including the steps of defining a small end of a connecting rod assembly having a terminal end and then defining a pin bore extending through the small end of the connecting rod assembly. A pair of channels is formed on opposite sides of the small end of the connecting rod assembly wherein the axis of each of the channels is substantially perpendicular to the axis of the pin bore. A bushing having a contact surface including at least partially annular grooves disposed thereon is installed into the pin bore of the small end. The connecting rod is then machined to reduce the width of the small end between each channel and the terminal end wherein at least a portion of the grooves are disposed along the distal ends to reduce the need to deburr the area adjacent to the pin bore.

    摘要： A connecting rod assembly includes a first end and a second end having bore extending therethrough and adapted to be aligned with a piston pin bore and receive a piston pin. The second end further includes a terminal end and has a reduced width configuration. The reduced width configuration is formed by machining a pair of channels that are formed on opposite sides of the second end between each channel and the terminal end. The bushing includes at least partially annular grooves disposed on the contact surface along at least a portion of opposed distal ends, where the grooves substantially eliminate the need for the small end to undergo a deburring process after the second end is machined to provide a reduced width configuration.

    摘要： A vehicle brake actuator including an improved piston assembly having a piston plate including an upstanding annular rim portion and a piston rod including a shank portion having a generally cylindrical head portion and an annular rim portion on a free end of the piston rod head portion which is deformed radially into a cylindrical internal surface of the piston plate upstanding rim portion, permanently attaching the piston plate and rod. The method includes piercing and extruding the upstanding rim portion of the piston plate and forming radially projecting teeth on an external surface of the head portion of the piston rod, driving the head portion of the piston rod into the upstanding rim portion of the piston plate, preventing relative rotation of the piston rod and head. The improved piston assembly of this invention eliminates welding, permitting finishing of the piston rod and plate prior to assembly and reduces cost.

    摘要： A ball and socket joint and method of making in which a piston, especially a compressor piston, and most particularly a piston for a compressor that pumps refrigerant, has a top wall and a depending skirt and is connected to the upper end of a connecting rod by a ball joint which is made by forming a spherical socket in the upper end of the connecting rod and riveting a ball to the underside of the top wall of the piston and forming the upper peripheral region of the socket of the connecting rod around the upwardly facing side of the ball. In practice, the ball is placed in the socket of the connecting rod and the rod is formed about the ball and then the ball is riveted to the piston.
