Optimization of the characteristic spring curve of a spring-damper assembly for a vehicle suspension

摘要

In a method for optimizing the spring characteristic of a spring damper unit (1) for a vehicular suspension system is at a in a vehicle axle (2) built-in spring damper unit (1) acting on a piston rod guide member transverse force F _Q and the associated Dämpfereinschubweg S measured _D and the corresponding F _Q / S _D -Federkennlinie _{installation is} created. Then, the F is _Q / S _D -Federkennlinie _testing, the supporting spring _(9), the spring damper unit (1) in a spring testing machine (18), whereby the angle of the support spring axis to Prüfmaschinenachse (19) corresponds to the angle of the support spring axis to the piston rod axis in the installed position , By superimposing the two F _Q / S _D -Federkennlinien a new F _Q / S _D -Federkennlinie _{testing should} be intended for the suspension spring (9). Further, a measuring element (14) for measuring the force acting on the piston rod guide element transverse force F _Q is proposed.
