Title Design of the Mini Car Clutch
Abstract
The mini car plays an important role in today's automobile market and it has a great role to play in this development. As an important component of the automobile transmission,the clutch has great influence on the vehicle performance.So the study or design of the mini car clutch is quite important. In this paper,the diaphragm spring clutch is designed for the mini car. Parameters and structure of main parts are determined and checked. The design of the main content includes: The main parameters of the clutch selection, including the reserve coefficient, friction plate inside and outside diameter, unit pressure, friction plate thickness, etc.The design of driven parts,including the design of a driven disc hub and a driven piece. The design of active parts,including the design of pressure plate and clutch cover.The design of the control mechanism,including the design of isolation bearing and torsional vibration damper.What’s more, engineering drawing by AutoCAD is needed.The results meet the requirements.
Keywords Clutch The friction plate Diaphragm spring Pressure plate
