In order to solve severe transmission gear rattle problem on the vehicle creeping condition, a new three-stage stiffness clutch damper is designed and developed. The performance of the new three-stage stiffness clutch damper is validated by specific bench test and vehicle experiment. Firstly, characteristics of a conventional driven-disc torsional damper are introduced. Then a new three-stage stiffness clutch damper is proposed innovatively and its working principle is described. Secondly, by the specific bench test, torque transmission property of a conditional driven-disc clutch damper and a new three-stage stiffness clutch damper are obtained. Mechanical structure and performance parameters design of the new three-stage stiffness clutch damper are validated.Finally, experimental test process and sensor layout are designed in the vehicle road experiment. The damping performance of a conventional driven-disc torsional damper and the three-stage stiffness clutch damper are compared through these results in time domain, frequency domain and time-frequency domain. It's concluded that the new three-stage stiffness clutch damper could be adopted to inhibit severe driveline torsional vibration and transmission gear rattle problem on the vehicle creeping condition.
