Definitions

  • the drive belt may experiences other situations that cause audible vibration and undue wear.
  • a serpentine arrangement with conventional driven pulleys may be used with an automobile engine that has an extremely low idle engine speed (which may increase fuel economy).
  • the arrangement typically experiences "belt flap" of the drive belt as the periodic cylinder firing of the automotive engine causes the arrangement to resonate within a natural frequency and cause an audible vibration and an undue wear on the drive belt.
  • This invention provides an over-running clutch pulley with features intended to increase wear resistance, while minimizing the costs and weight of the over-running clutch pulley.
  • FIG. 2 is a partial cross-section view, taken along the line 2-2 of FIG. 1 , of the overrunning clutch pulley of the preferred embodiment.
  • the sheave clutch section 34 and the hub clutch section 40 of the preferred embodiment function to provide the sheave clutch surface 36 and the hub clutch surface 42, respectively, for the engagement with the clutch member 24.
  • the sheave clutch section 34 preferably extends radially inward from the sheave member 20. In this manner, the sheave clutch section 34 is preferably made from the same material and with the same methods as the sheave input section 32, but may alternatively be made from other suitable materials and with other suitable methods.
  • the hub clutch section 40 preferably extends radially outward from and axially over the hub output section 38. In this manner, the hub clutch section 40 is preferably made from the same material and with the same methods as the hub output section 38, but may alternatively be made from other suitable materials and with other suitable methods.
  • the sheave clutch surface 36 and the hub clutch surface 42 cooperate to define a clutch free volume 68 surrounding the clutch member 24.
  • the clutch lubricant 26 occupies from approximately 50% to approximately 90% of the clutch free volume 68, and the bearing lubricant 30 occupies from approximately 20% to approximately 45% of the bearing free volume 66. In alternative embodiments, the clutch lubricant 26 may occupy more or less than the preferred percentage, and the bearing lubricant 30 may occupy more or less than the preferred percentage.

Abstract

L'invention concerne une poulie à roue libre. Dans une réalisation préférée, cette poulie comprend un élément réa (20), un élément (22) moyeu situé de manière sensiblement concentrique à l'intérieur de l'élément réa, un élément (24) d'embrayage, un lubrifiant (26) d'embrayage inséré dans la région de l'élément d'embrayage, un élément (28) de roulement placé entre l'élément réa et l'élément moyeu, et un lubrifiant (30) de roulement inséré dans la région de l'élément de roulement, qui coopèrent pour entrer en contact rotatif avec un dispositif (12) d'entrée et un dispositif (14) de sortie. L'élément réa comprend de préférence une partie (32) entrée de réa conçue pour entrer en contact avec un dispositif d'entrée, et une partie (34) embrayage de réa définissant une surface (36) d'embrayage de réa. De façon similaire, l'élément moyeu comprend de préférence une partie (38) sortie de moyeu conçue pour entrer en contact avec le dispositif de sortie, et une partie (40) embrayage de moyeu qui définit une surface (42) d'embrayage de moyeu. Le lubrifiant (26) d'embrayage et le lubrifiant (30) de roulement comprennent de préférence un composant de base sélectionné dans le groupe comprenant les éthers, les esters et les huiles minérales.
