Abstract
Official abstract text for this publication.
A system and method for determining a remaining useful life of a portion of a wet clutch system is provided. The system comprises a first clutch assembly, a proportional valve, a sensor, and a controller. The proportional valve regulates a pressure applied to the first clutch assembly. The sensor measures a response of the first clutch assembly during one of engaging and disengaging a first portion of the first clutch assembly with a second portion of the first clutch assembly. The controller controls the proportional valve, calculates a mean coefficient of friction of the first clutch assembly based on the sensed response of the first clutch assembly, and determines a remaining useful life of a portion of the wet clutch system based on the mean coefficient of friction of the first clutch assembly.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining a remaining useful life of a portion of a wet clutch system, the method comprising the steps of: providing the wet clutch system, the wet clutch system comprising: a first clutch assembly rotatingly disposed in a housing, a first portion of the first clutch assembly drivingly engaged with an input member and a second portion of the first clutch assembly drivingly engaged with an output member, a proportional valve for regulating a…
