ABSTRACT
Clutch auto transmission system is an important part of the design, were the main car diaphragm spring clutch structure design.The main design of a vehicle diaphragm spring clutch design of the structure. First, the diaphragm spring clutch of motor vehicles and development of the diaphragm spring clutch system components and principle. And then, of diaphragm spring clutch parts of the structure and the working principle, and in the light of the detailed discussion LuBao hafei car LuBao vehicles related technical parameters read according to the current situation of the development of the clutch, not yet solved problems, and primary rumsfeld diaphragm spring clutch of basic structure size parameters.Then, the diaphragm spring clutch part of the structure and working principle of a detailed exposition, and a model for access to the relevant national standards and diaphragm spring primaries push-type clutch size of the basic structure of parameters. , Under the push-type diaphragm spring dual-clutch performance requirements, and identify the major components of the structure, size and specific design parameters, check and correct. Finally, the use of Auto-CAD drawing push-type diaphragm spring clutch parts of the main components of the plan and the system assembly.
