Abstract
Methods and systems are provided for an isolator. In one example, system may include an isolator comprising a flexible laminated membrane comprising a non-linear torsional stiffness for compensation of axial, lateral, and angular displacements between a drive shaft and a clutch.
Claims18
A system, comprising:
- a drive shaft coupled to a belt pulley, wherein a flexible laminated membrane decoupler is arranged at an interface between the drive shaft and a rotor, wherein the flexible laminated membrane decoupler comprises a plurality of openings including a first pair and a second pair, and wherein the first pair is coupled to the drive shaft and the second pair is coupled to the rotor.
A front end accessory drive, comprising:
- a flexible, laminated decoupler configured to flex in an axial, a lateral, and an angular direction relative to a central axis of a one-way clutch and a shaft, wherein the decoupler is one of a plurality of decouplers and the shaft is a first shaft, wherein a first decoupler is arranged between the first shaft and a second shaft, wherein a second decoupler is arranged between the second shaft and a rotor, and wherein the second shaft is different than the first shaft.
An engine system, comprising:
- a pulley system comprising a drive shaft, a one-way clutch, a connecting shaft, and a rotor, further comprising a first flexible laminated membrane is arranged between the drive shaft and the connecting shaft, and a second flexible laminated membrane is arranged between the connecting shaft and the rotor, wherein each of the first and second flexible laminated membranes are configured to flex in axial, lateral, and angular directions relative to a central axis of the drive shaft and the connecting shaft.
