Definitions

  • the invention relates to a support sleeve for a washing brush of car washes with the features in the preamble of Main claim.
  • Such a support sleeve is known from US-A-4,338,698. It has several clamping grooves on the circumference for receiving Loops of the brush trim. For fixation Clamping pins are provided which are stuck in the loop the clamping groove are inserted. With the shown Terminal arrangement is only an axial assembly of the Carrying sleeve with the brush trim possible. In addition, the Trim loop with the inserted pin under Clamping tension can be inserted into the groove. This complicates and increases the cost of assembly.
  • the invention solves this problem with the features in the main claim.
  • the inventive design of the support sleeve facilitates the assembly of the brush trimmings.
  • the design of the clamping pins as rotary pins with a widened shaft means that assembly can be carried out largely without clamping voltage. The clamping force or clamping voltage is only produced after the rotary pin has been actuated. With the rotation lock, the pivot pin can be fixed in the desired locking position.
  • the support sleeve according to the invention has the advantage that radial mounting of the brush trim is also possible. With appropriate adaptation of the shaft dimensions of the clamping pin to the access opening of the clamping groove, the trimmings loops can be inserted radially into the clamping grooves with the clamping pin. This makes assembly easier.
  • the brush trim can also be assembled by hand and, if necessary, replaced in places in the event of wear or damage.
  • the support sleeve is divided into several sleeve rings, that can be assembled individually. Due to the Vehicle contour is created with the washing brushes Length mostly an uneven brush wear.
  • the sleeve rings in the wear-prone area replace and the sleeve rings with the still usable Leave brush trimmings.
  • the sleeve rings can be interchanged to compensate for wear. Compared to the state of the art, which is usually due to wear requires a complete replacement of the brushes, is with possible partial exchange of the invention essential cheaper and easier. They can also Maintenance and exchange work also by the operator of the Car wash and do not require any Skilled personnel.
  • the support sleeve it is also convenient to use the support sleeve to mount on a support tube and thereby a Inner guide for the support sleeve or sleeve rings to have.
  • Such training facilitates maintenance and Exchanges.
  • the support sleeve relieves the strain and can be done from a less firm Material, e.g. Plastic.
  • an internal support tube If an internal support tube is arranged, it is cheap, through a mutual profiling rotational connection between support sleeve and support tube to manufacture. Additional fixation measures for the This eliminates turning entrainment. Of special It is advantageous if the support tube is on the outside Ribs and the corresponding support grooves exhibit. This allows the one hand Optimize material use and on the other hand an optimal one Achieve strength of the support tube.
  • the outside Ribs of the support tube can also be internal Mounting holes, e.g. Screw openings for direct Have attachment to the motor flange. A special radially protruding pipe flange is therefore unnecessary. In addition, due to the outer ribs Screw holes or fastening screws a larger one Center distance and can transmit larger moments.

  • She has one Counter-profiling (15) and is rotatably on it Support tube (2) held.
  • the counter-profiling (15) can Fully or partially rest on the outer contour (7).
  • the profiling of the outer contour (7) of the support tube (2) is preferably formed by the ribs (5) on The support tube (2) is on the outside.
  • the ribs (5) are preferably narrow and just so thick that the Pick up the fastening openings (11).
  • the Ribs (5) bulge radially outwards over the normal Outer tube circumference.
  • the mounting holes (11) are also far outside and are outside the normal pipe outer circumference. Due to the large distance of the Fastening openings (11) can generate high drive torques be transmitted. Alternatively, the Pipe diameter can be reduced.
  • the positive connection between the support tube (2) and the support sleeve (9) lies in the region of the ribs (5) and the mounting holes (11).
  • the mounting holes (11) are therefore also in the area of the support sleeve (9).
  • Figures 3 and 8 show a support tube variant in the form of a Circular tube (3) with external ribs (5).
  • the cylindrical inner tube wall serves as Centering surface (12) for the motor flange (13).
  • Ribs (5) protrude beyond the outer wall of the circular tube (3).
  • the support tube (2) is as Profile tube (4) formed, the tube wall Wave profile with external ribs (5) having.
  • the pipe wall has between the ribs (5) concave indentations (8) leading to the interior Pipe axis (6) are curved. This even and form indentations (8) distributed regularly in a circle with their inner vertices an enveloping circle, which also has a centering surface (12) for the Motor flange (13) creates.
  • the Ribs projecting outwards over the tube wall (5) together with the indentations (8) for the positive connection between the support tube (2) and support sleeve (9).
  • the Fastening openings (11) are in both Variants of Figure 3, 7 and 8 with a radial distance outside the centering surfaces (12) or enveloping circles.
  • the support tube (2) or the support sleeve (9) have one Outside diameter that is equal to or greater than 120 mm.
