Movement converter for converting rotational movement into linear movement in e.g. joystick, has three drive devices producing linear movements in respective movement directions that are arranged at specific angle to each other

摘要

The converter (1) has three drive devices (12-16) producing linear movements in respective movement directions (R1-R3). The drive devices are controlled and connected with different points (A-C) of a base element (2), where the different points are firmly connected with one another. Two of the motion directions are occasionally arranged at angle of 0 and 180 degrees to each other. Position detecting devices (16, 22, 24) are provided for detecting the linear movements in the respective movement directions. The drive device is selected from a group consisting of a linear motor, hydraulic drive, pneumatic drive and piezoelectric drive. An independent claim is also included for a method for converting movements.
