摘要:PCT No. PCT/EP93/02468 Sec. 371 Date May 22, 1995 Sec. 102(e) Date May 22, 1995 PCT Filed Sep. 13, 1993 PCT Pub. No. WO94/07390 PCT Pub. Date Apr. 14, 1994The invention relates to a brush head for large manipulators with a brush roller fitted on a motor-driven brush shaft (56) having flexible, centrifugally born bristles (66) and divided into at least two axially separated roller sections (58) and with at least one torque sensor arranged between the brush shaft (56) and the individual roller sections (58). In order to ensure reliable torque detection for the automatic positioning and directing of the brush head, the invention proposes that the brush shaft be also divided into a number of shaft sections (56) corresponding to the number of roller sections (58), the mutually allocated roller and shaft sections be interconnected by axially and radially rigid and circumferentially flexible spacers (60), the torque sensors have a weighing cell (68) projecting radially over the shaft section (56) concerned towards the roller section and a flexible tensioner (70) extending substantially tangentially between the weighing cell and the inside of the relevant roller section (58) against the direction of rotation, and that the brush sections (48', 48'', 48''', 48IV) made up of the shaft sections (56) and roller sections (58) be mutually tensioned via a tension rod and connected to the frontal motor drive system.
