Abstract: The invention relates to a method of finishing a metal preform. The preform is green machined in a first method step. Next, the quality surfaces, which, on the finished component part are to meet stringent quality requirements, are roller burnished. Finally, the preform is hardened.

Abstract: An anti-shudder constant velocity universal joint of the tripod type is provided having an outer joint member including three circumferentially distributed, axially extending longitudinal tracks formed therein, and an inner joint member having three circumferentially distributed radial journals arranged to engage the longitudinal tracks when the joint is assembled. The end of each journal is mated with and supports rotation of a roller bearing assembly, while rotating and pivoting within the roller bearing assembly upon articulation of the joint. This reduces the frictional forces on the roller bearings created by maintaining the roller bearings in a relatively proper/parallel orientation within the tracks by allowing the journal ends to freely rotate and pivot therein. A spherical-to-spherical contact surface is provided between the journal ends and an inner ring of the respective roller bearing assemblies to lower Hertzian stresses by distributing forces over a larger region of contact.

Abstract: A composite linkshaft bracket having a composite upper portion and a lower portion used to support a bearing supported linkshaft in a vehicle driveline replaces known cast iron brackets. The composite upper portion is formed of a polymer material that is designed for sufficiently high eigenfrequencies due to a low specific weight and high stiffness and the ability to withstand heat distortion temperatures of at least 180 degrees Celsius. Preferably, the polymer material is reinforced with fibrous material such as glass fiber. The lower portion is preferably formed from the same polymer material used in the composite upper portion, however may alternatively be formed of stamped metal.

Abstract: A device for transmitting the position of a drivebelt pulley of a continually variable automatic transmission to a valve arrangement includes a lever assembly extending between the valve and a variable displacement abutment connected to a sensor foot contacting the pulley. The position of the sensor foot is displaceable on an axial guide rod according to the position of a threaded bushing. The position of the pedal is adjustable from outside the transmission housing by rotating a tool that turns a setting sleeve rotatably fixed to the guide rod. As the guide rod turns, the bushing, engaged with threads on the sensor foot, changes the position of the abutment contacted by the lever assembly.
