Abstract
Regarding take the internal combustion engine as the power automobile, the coupling is takes an independent unit in the mechanical power transmission to exist, it is in the automobile power transmission direct and the engine connected unit. At present, each kind of automobile widely uses the friction clutch is one kind depends upon between the main secondary part the friction to transmit the power, and can separate installment. It mainly includes the driving part, the secondary part, the compaction organization, and the control mechanism and so on four parts. Coupling's function main function is shuts off and realizes the engine to the power transmission power transmission, guarantees the automobile starts when the engine and the power transmission joins smoothly, guaranteed that the automobile starts steadily; When shifting gears separates the engine and the power transmission, reduces in the transmission gearbox between change gear's impact; Receives when the work big moves the load, can limit the biggest torque which the power transmission withstands, prevents power transmission various components because to overload damages; Reduces in the power transmission effectively the vibration and the noise. This design including the coupling various components' structure, the coupling main parameter's choice and the optimization, disk spring's computation and the optimization, the reverse shock absorber's design, the coupling control mechanism's design calculation and is related the design paper, finally has composed the instruction booklet. Has certain research value to the coupling design.
key word: The coupling, pushes the type disk spring, the structural design
