Backlash-free disk pack coupling in Formula 1 driving simulator
The world-wide patented backlash-free ROBA -DS shaft couplings produced by mayr Antriebstechnik transmit the torque wi th high torsional rigidi ty and compensate for axial, angular and radial shaft misalignments . They have proved themselves as the ideal couplings for many direct-powered servo axes and are constantly being tried out with success on new applications, for example in the drive unit of a driving simulator.
In the Formula 1 driving simulator produced by the British company Ball Racing Developments (BRD), the driver sits in an original F1 racing car and drives down a fictional track which they view on the flat screens positioned in front of them. As when driving a real car, certain forces affect the driver when they accelerate, brake or drive round corners. In order to generate the centrifugal forces which occur when driving round corners, the vehicle is moved quickly to the left or the right in the area of both axes. If the vehicle is moved backwards or forwards along the longitudinal axis, the driver is pressed into the seat or against the safety belt just as when carrying out real braking and accelerating manoeuvres.

Spindles are used to generate the left-right movement in the area of the vehicle axes. These spindles are driven via toothed belts. Adirect-powered spindle axis pushes the vehicle along the longitudinal axis. A backlash-free, torsionally rigid disk pack coupling from the ROBA-DS series is located between the servomotor and the spindle. This compensates for angular and axial shaft misalignments such as those caused by heat expansion. The ROBA-DS servo coupling in single-joint design has an extremely compact form and impresses customers with its exceptionally low mass moment of inertia. This makes it ideal for this application and for many other servo technology applications.
The world-wide patented, backlash-free haft couplings are torsionally rigid but bend-flexible, and compensate for axial, angular and radial shaft misalignments. Their range of application s constantly increasing due to consistent extension of the size and variant possibilities. This series, conceived especially for servo technology, comes in sizes 3, 6, 10 and 15 in a diameter range of 45 to 79 mm to cater for torques from 35 to 150 Nm. Their characteristics are as follows: low mass moment of inertia due to compact assembly and the use of aluminium instead of steel as well as shaft-hub connections specially adapted for servo applications.
