Abstract

The invention relates to a device for cleaning vehicle wheels that contains a rotary body driven rotationally by a drive motor about a central axis, with cleaning elements arranged on its front end face. An improved cleaning can be achieved by virtue of the fact that the rotary body contains at least one rotary plate equipped with additional cleaning elements that is rotated by the rotation of the rotary body, not only about the central axis but also, via a gear assembly, about its own longitudinal axis.

Claims

1. A device, in a vehicle washing system, for cleaning wheels on a vehicle, comprising:

a rotary body driven rotationally by a drive motor about a central axis, the rotary body including a front end plate having at least one substantially circular opening;

a first group of cleaning elements arranged on the front end plate;

at least one rotary plate having a longitudinal axis arranged within the substantially circular opening in the front end plate of the rotary body such that the rotary plate does not protrude past the front end plate, the rotary plate having a diameter substantially equivalent to a diameter of the circular opening, the rotary plate rotatable by rotation of the rotary body about the central axis and about its own longitudinal axis via a gear assembly; and

a second group of cleaning elements arranged on a front face of the at least one rotary plate;

wherein the device is coupled to the vehicle washing system, where during operation a vehicle is enclosed by the vehicle washing system such that the wheels of the vehicle are placed adjacent the device and the cleaning elements contact and clean the wheels.

2. The device according to claim 1, wherein the at least one rotary plate is driven by the gear assembly at a speed different from rotational speed of the rotary body.

3. The device according to claim 1, wherein the rotary body is fixedly connected to a driveshaft rotatable by the drive motor.

4. The device according to claim 1, wherein the gear assembly is constructed as a planetary gear unit having a sun wheel rotationally fixedly arranged inside the rotary body and a planetary gear associated with the at least one rotary plate.

5. The device according to claim 4, wherein the sun wheel is arranged on a non-rotatable bearing bushing protruding into the rotary body.

6. The device according to claim 4, wherein the planetary gear is arranged proximate to a shaft arranged inside the rotary body via bearings.

7. The device according to claim 1, wherein the front end plate is mounted on an intermediate member of the rotary body.

8. The device according to claim 7, wherein the intermediate member is connected to a rear cover plate of the rotary body.

9. The device according to claim 1, further comprising a cleaning agent supply system integrated into the rotary body.

10. The device according to claim 9, wherein the cleaning agent supply system includes a supply line and a rotary feed-through for supplying cleaning fluid via a central supply channel.

11. The device according to claim 1, wherein the rotary body includes a plurality of rotary plates distributed about the central axis.

12. A cleaning device, in a vehicle washing system, for cleaning wheels on a vehicle comprising:

an end plate having a front side and a rear side, the end plate rotatable about a central axis by a drive shaft connected to the rear side of the end plate;

a plurality of openings in the front side of the end plate;

a plurality of rotary plates, each of the plurality of rotary plates arranged in each of the plurality of openings such that each of the rotary plates does not protrude past the end plate, each of the rotary plates having a diameter substantially equivalent to a diameter of each of the plurality of openings, each of the plurality of rotary plates rotable about a rotary axis substantially parallel to the central axis of the end plate cleaning elements arrange on the front end plate and/or the plurality of rotary plates; and

a supply line including at least two sections, each section arranged diametrically opposite the other section on the drive shaft, a first open end of each section extending into or through a hole in the end plate, wherein the supply line is operable to pass a fluid through the supply line and onto multiple points on the front side of the end plate;

wherein the device is coupled to the vehicle washing system, where during operation a vehicle is enclosed by the vehicle washing system such that the wheels of the vehicle are placed adjacent the device and the cleaning elements contact and clean the wheels.

13. The cleaning device according to claim 12, wherein a second end of each section is connected to a central supply channel, thereby permitting a fluid to pass from the central supply channel through the sections, the fluid dispensing onto the front side of the end plate.

14. The cleaning device according to claim 12, wherein the drive shaft is connected to a sun wheel and each rotary plate is connected to a planetary gear, each planetary gear meshing with the sun wheel, thereby permitting rotation of each rotary plate about its respective rotary axis, in addition to rotation about the central axis by the drive shaft.

15. A device for cleaning a vertical surface, comprising:

a carriage;

a drive shaft having a fluid passing channel therein, the drive shaft rotatable with respect to the carriage;

a plate connected to the drive shaft and rotatable together therewith with respect to the carriage;

a gear assembly including a sun wheel operatively connected to the carriage;

a plurality of planetary gears meshed with the sun wheel, each of the plurality of planetary gears having a central axle connected to the plate and rotatable together therewith, each of the plurality of planetary gears rotatable about its central axle by the sun wheel when the plate is rotated with respect to the sun wheel;

a plurality of rotary plates arranged within openings in the plate connected to the drive shaft such that rotary plates do not protrude past the plate, each of the plurality of rotary plates having a diameter substantially equivalent to a diameter of the openings, each of the plurality of rotary plates operatively connected with each of the plurality of planetary gears;

a plurality of brushes, each of the plurality of brushes connected to one of the planetary gear axles to be rotated together therewith;

at least one fluid supply line communicatively coupled to the fluid passing channel of the drive shaft to dispense a fluid proximate the vertical surface to be cleaned; and

a guide connected to the carriage and configured to move the carriage between a position distal to the vertical surface to a position proximate the vertical surface for cleaning.

16. The device according to claim 15, wherein the fluid supply line includes a plurality of supply tubes, an open end of each of the plurality of supply tubes connected to the plate and extending towards the vertical surface to be washed, the open end of each of the plurality of supply tubes rotatable with the plate.

17. The device according to claim 16, wherein an open end of at least one of the plurality of supply tubes is positioned proximate at least one of the plurality of brushes to apply fluid to at least one of the plurality of brushes.

18. The device according to claim 15, wherein the guide is configured to move the carriage along a predetermined path between the position distal to the vertical surface and the position proximate the vertical surface.

19. The device according to claim 15, wherein the plate further comprises a brush connected to an end of the drive shaft.
