Typically in early phases of product development processes, it is necessary to get useful results by a purposeful modeling, which deepens the system understanding as soon as to supply an established basis to decide between different concepts. This paper will deal with that by the example of a model based validation of a back torque limiter. Back torque limiters are increasingly widespread in motorcycle applications and serve to avoid a blocking driving wheel at high coasting torques. This type of back torque limiter transfers the clutch of the power train in slip in order to avoid the blocking of the driving wheel. The simulation model of the back torque limiter is implemented on the base of a motorcycle application. It models a ramp system and a preloaded diaphragm spring package. This model cannot only simulate as a sub system, but it can also be implemented in the remaining model of the power train system. Therefore, it is possible to analyze the behavior and interactions of the back torque limiter and the complete motorcycle system and finally validate it. The back torque limiter and the respective clutch are tested on a test bench, which contains mainly two electric motors and measurement devices for torque and axial forces. In addition, it is shown how the model can be used for further investigations and developments.
