Title: DEVICE FOR SIMULATING A FORCE ON AN ACTUATION ELEMENT OF A VEHICLE, IN PARTICULAR A PEDAL FORCE SIMULATOR
Abstract:
The invention relates to a device for simulating a force on an actuation element of a vehicle, in particular a pedal force simulator, comprising a housing (10), a piston (20) which can be moved axially in the housing (10), said piston (20) being connected to the actuation element via a piston rod (30), and a spring element (40) which is arranged at least partly within the housing (10), in particular completely within the housing. According to the invention, the piston (20) has a changing cross-section and engages into the spring element (40) upon being actuated by the actuation element. The spring element (40) is equipped with rolling bodies (70, 80) which are operatively connected to the piston (20), and the spring element (40) consists at least of a first and a second spring part (50, 60) which are connected together.
