Experimental Measurement to Predict Power Steering Pump Hub Load with Implementation of Belt Driven Starter Generator

The present scenario in automobile industry is formed on developing smart vehicles by introducing various feature towards fuel efficient, low emission, weight reduction, and advance safety feature with hybrid and micro-hybrid vehicles. One such feature gaining more popularity is the Belt Driven Starter Generator [1] for its contribution towards fuel efficiency, emission reduction [2], weight reduction and convenient packaging with engine/electrical interface. However this invention puts challenge of integration and increase in loading to various system like power steering pump and crank shaft pulley, as all these systems are interlinked with a common belt. In this interface links we observed the steering pump hub under risk of structural failure due to additional load to support Belt Driven Starter Generator. Failure to identify safe limits of hub load can affect safe vehicle operation [3]. This paper deals with vehicle level measurement on steering pump hub load with /without belt driven starter generator. It also deal with acquiring steering pump hub load under various operation modes of belt driven starter generator. This exercise shall lead to significant study and feasibility of steering pump working with belt driven starter generator.
