Buerstenkopf fuer Grossmanipulatoren

The brush shaft is divided into a number of sections (56) matching the number of roller sections (58). The concentric roller and shaft sections are joined by peripherally flexible, radial spacer pieces (60) which are axially and radially rigid. The torque pickups have a weighing cell protruding radially beyond the appropriate shaft section towards the roller section, as well as a tension member extending tangentially towards the direction of rotation and positioned between the weighing cell and the inside of the appropriate roller section. ADVANTAGE - The torque pickup for automatically guiding the brush head on the surface being cleaned operates reliably.
