- FIG. 7 shows a perspective illustration of the drive 00222 shaft area according to FIG. 4; 00223 00224 Fig.
- FIG. 8 shows a detail of the clutch area between the drive shaft and the brush body, 00226 with a sectional view of the brush body 00227 pers; 00228 00229
- Figure 9 shows the section along the line IX-IX in Figure 8, 00230 but omitting the drive shaft and 00231 driving elements.
- FIG. 10 shows a representation corresponding to FIG. 9, 00234 but in the 00235 state of the brush body which is plugged onto the drive shaft; 00236 00237
- FIG. 11 shows a representation corresponding to FIG. 10, 00238 but after turning the brush body 00239 into a non-positive locking or 00240 driving position.
- a motor-driven brush device 1 which 00244 in the exemplary embodiment shown as an attachment 00245 is designed for a vacuum cleaner.
- the Bürstenge ⁇ 00246 advises 1 is composed essentially of a housing 2 00247 and a pipe connection piece 3.
- se 2 extends a suction channel 4, starting from the pipe connection 00249 connecting piece 3, into a suction space 5.
- 00250 The latter is located in an end area 00251 which faces away from the pipe connecting piece 3 and 00252 extends almost over the entire housing width 00253 (see Fig. 2).
- a separate drive 00256 6 is arranged in the housing 2, which rotates a drive shaft 8 which extends 00257 into the suction chamber 5 via a toothed belt 7.
- the toothed belt 7 lies in a belt housing 9 which is pivotally mounted on the end facing away from the drive shaft 8.
- the 00261 swivel axis also forms the power transmission axis 00262 from the separate drive 6 on the toothed belt 7 and 00263 is parallel to the drive shaft 8.
- 00264 00265 The toothed belt drive or the belt housing 9 er ⁇ 00266 extends approximately from the center of the suction chamber 5 starting 00267 perpendicular to the drive shaft 8.
- the toothed belt 00269 7 engages a drive pulley 11 on 00270, from which the drive shaft 8 divided on both sides extends.
- the latter thus extends 00272 from the drive disk 11, starting from 00273 to a lateral end region of the suction space 5.
- Each drive shaft 8 has a driver 12 approximately in the middle of its longitudinal extension 00276.
- 00277 00278 In FIG. 2, the brush device 1 is in one Bottom view 00279 is shown, the bottom 13 in the area of the suction space 5 00280 of the brush device 1 is partially broken.
- Each brush body 16 is designed as a hollow body 00297 det and is provided on the outside with two rows of bristles 17 arranged offset by 180 °, which starting from 00299 an end region of the brush body 16, around 00300 about 180 ° spirally around the latter extend.
- 00301 00302 The brush bodies 16 are plugged onto the drive shafts 8 00303 and, in the installed state 00304, extend approximately from the gear housing 10 to the 00305 end region of the suction chamber 5.
- the power transmission from 00306 of the drive shaft 8 to the brush body 16 takes place 00307 via the driver 12 of the drive shaft 8.
- 00308 00309 The driver 12 of the drive shaft 8 is shown in FIGS.
- the driver 12 essentially consists of a cylindrical sleeve 18 with jacket elements 19 arranged on the outside of the jacket. 00315 sets. There are three driving elements 19, 00316 which are uniformly distributed over the circumference of the sleeve 18 00317 with this material. 00318 00319 The driving elements 19 are essentially plate-like 00320 and in a projection into a 00321 plane have an essentially square plan, 00322 whereby two opposite corner areas of this 00323 approximate square plan are aligned parallel to the 00324 shaft axis x (cf. Fig. 5). According to FIG.
- each driving element 19 in a 00326 projection according to FIG. 5 is rotated approximately 45 ° with respect to the end faces 20 00327 and 21 of the sleeve 18, with which 00328 sloping flanks on the driving element side are formed.
- the inclined flanks 00329 facing the end face 20 serve as 00330 transmission faces 22.
- the tip area between 00331 these two transmission faces 22 is slightly rounded, the apex of this rounding being level with 00333 the end face 20 of the sleeve 18.
- each driving element 19 is approximately symmetrical to 00336 a plane E, which is perpendicular to the shaft axis x and is 00337 central to the driving element 19, 00338 det.
- the 00339 inclined flanks opposite the transmission surfaces 22, based on the central plane E, are designed as guide surfaces 23.
- the 00341 corner area between these guide surfaces 23 is strongly rounded 00342 to form an end-side curvature surface 23 ', the apex of which is positioned at the level of the end surface 00344 of the sleeve 18.
- 00373 27 corresponds approximately to the axial length of the sleeve 18.
- the entrainment protrusions 26 either enter directly into the locking openings 25 or, if these openings 25 are not found directly, through the guide surfaces 00391 23. This is done in such a way that when the driving projections 26 hit 00393 the curved end face 23 'or on the deflector surfaces 00394 chen 23 under slight pressure by the user 00395 the projections 26 slide along the deflector surfaces 00396 chen 23.
