Appl. No.:

10/939840

Inventors:

Randy C. Foster - Strafford MO, US

Assignee:

Dayco Products, LLC - Miamisburg OH

International Classification:

F02N 7/00
F02N 11/00

US Classification:

1231794, 12317931, 60627, 60629

Abstract:

An automotive starting system includes an accumulator, a hydraulic motor, and an engine controller. The accumulator is adapted for holding a charge of pressurized fluid. The hydraulic motor has a fluid input operatively connected to the accumulator and has an output shaft operatively connected to an internal combustion engine of an automotive vehicle. The engine controller shuts off the engine if an idle engine condition exists and restarts the engine using the hydraulic motor following an idle engine shut-off if a predetermined engine-start condition exists. A method for starting an internal combustion engine of an automotive vehicle includes having the engine controller shut off the engine if an idle engine condition exists and thereafter having the engine controller restart the engine using the hydraulic motor if a predetermined engine-start condition exists.

International Classification:

F16H 7/08
F16H 7/12

US Classification:

474110, 474135

Abstract:

A tensioner for a power transmitting belt is provided having a base, an arm pivotably attached to the base, a pulley rotatably attached to the arm and a spring operatively connected to the arm and the base for urging the arm in direction to tension the belt. A hydraulic strut is pivotably attached to the base and the arm to restrict the movement of the arm through asymmetric fluid damping. The hydraulic strut includes a hydraulic cylinder filled with magnetorheological fluid, a piston rod axially mounted through the cylinder and a piston mounted on the piston rod to divide the cylinder into first and second fluid chambers. The strut further includes a fluid flow path between the first and second fluid chambers, a check valve in the fluid flow path to provide asymmetric fluid flow and a coil that is operable to generate a magnetic field across the fluid flow path when energized. When the coil is energized fluid flow between the first and second fluid chambers is halted such that the arm of the tensioner locks up.

Abstract:

A belt tensioner includes a support housing at least in part defining a spring cavity and an arm pivotally attached to the support housing. A spring is located in the spring cavity and is operatively connected to the arm and the support housing to bias the arm about a pivot axis toward an unloaded position relative to the support housing. A damping member includes a hub and deflectable, force-applying elements that are connected to and spaced apart about a periphery of the hub. The force-applying elements are biased toward a contact surface of the arm to apply a frictional force between the contact surface and the force-applying elements to impede rotation of the arm relative to the support housing.

US Classification:

249176

Abstract:

A mandrel for a molding system includes a support structure formed in a generally closed loop shape. The support structure is formed of a plurality of discrete segments coupled together. The number of discrete segments is increasable or reducible to change the overall geometry of the closed loop shape. The mandrel may be part of a molding system that includes a mandrel surface that closely fits about the outer surface of the mandrel body. The mandrel surface is formed of a plurality of discrete toothed segments that form a generally closed loop shape.

International Classification:

F16H 7/12

US Classification:

474135

Abstract:

A hydraulic damper for providing fluid damping to a tensioner in a drive system that includes a damper cup, which is mounted to the tensioner and configured to rotate about a central axle in tandem with the tensioner, an end plate having an outer face and an inner face, which is attached to the damper cup forming a fluid chamber, a pin attached to the end plate and extending away from the inner face and toward the damping cup, a damping fluid, which is contained within the fluid chamber, a rotatable plate having an opening configured to accept the pin through the rotatable plate and rotate about the central axle, and a fixed plate having an opening configured to accept the pin through the fixed plate, which is fixed to and does not rotate about the central axle. During wind-up and tensioning of the tensioner, a shear force is applied to the rotatable plate moving through the damping fluid to provide damping to the tensioner.
