Manipulationssimulator vom Typ mit Drehbewegungseingang

摘要

An object of the present invention is to impart a preferred continuous nonlinear characteristic to the relation between the magnitude of operation and an operational reaction force over the entire range of operation of operation means even when a reaction generation spring has a linear spring characteristic. A rotary-motion-input-type manipulation simulator includes an input member which rotates in accordance with a braking operation of a driver applied to a brake pedal; the brake pedal which rotates about the axis and imparts a rotary motion to the input member; a compression coil spring which generates a reaction force linearly according to an amount of deformation thereof; an output member which deforms the compression coil spring; and transmission apparatus provided between the input member and the output member and adapted to convert the rotary motion of the input member to a rectilinear motion and transmit the rectilinear motion to the output member and to transmit the reaction force of the compression coil spring to the input member via the output member. The transmission apparatus continuously and nonlinearly varies a ratio of an amount of rectilinear motion of the output member to an amount of rotary motion of the input member according to the amount of rotary motion of the input member.
