Analysis of the Car Clutch Pressure Plate Assembly Quality Characteristics

Abstract

The diploma thesis namely “Analysis of the Car Clutch Pressure Plate Assembly Quality Characteristics” is a work conducted to improve the quality of the friction plate clutch assembly, produced at the Indian company, by reducing the defects. Friction plate clutch has pressure plate assembly which contains pressure disc, diaphragm spring, fork lifter and thrown out pilot bearings. In this study, the author mainly focuses on various defects in the car clutch pressure plate assembly, the causes of defects and their impact. In this study, an analytical type of research was used to analyse the defects on pressure plate clutch assembly by collecting data, in order to determine the frequency of defects of various types. Further the author has used secondary data for the research study. The secondary data was gathered from the quality department at the mentioned Indian producer of the car clutches. These defect data are analysed by using quality control tools such as trend analysis, statistical hypothesis testing, Pareto analysis, control charts, cause and effect diagram. From the findings suitable suggestions to the company to overcome the defects of existing clutch assembly, to improve the customer satisfaction and also to improve business in future grounds are given.
