     2 DESCRIPTION Head for washing vehicle wheels Object of the invention 5 The present invention as expressed in the statement of this specification refers to a head for washing vehicle wheels that rotates driven by a motor element; where said head can be mounted on any vehicle washing machine. The new head can replace another mounted head without the need to manipulate or couple any additional mechanism as is happening conventionally. In addition, the new head of the invention allows the internal surface of the hollows of the wheel rims to be properly cleaned by introducing the bristles of some brushes into said tire recesses; where said brushes can be kept in a static position, but turning, when they are facing holes in the wheel rim during cleaning. 15 Technical problem to be solved and background of the invention At present, the wheel washer brushes of vehicles comprising a circular base where polyethylene bristles forming a uniform body are fixed are known. This brush model is perfectly functional when the wheel of the vehicle 20 to be washed incorporates a cover-buckets, which in most cases said cover-buckets is flat and has a simple shape. However, the inconvenience arises when the brush is not able to access the different grooves and holes of the wheel rims that exist in the market. 25 On the other hand, in the market there are in general several types of brushes to clean the wheels of vehicles. However, the operation of most of said brushes consists in spinning one or more brushes that are integral to a motor driven shaft. To date, all brushes maintain a rotation rate marked by the speed of rotation of the motor. 30 Apart from the fact that some manufacturers have developed systems that manage to spin more than one brush independently, these brushes are always accompanied by rotating rhythmically around a common axis. This situation causes that when not stopping any of the brushes in any position, it is impossible that the3 bristles of the brushes can penetrate the hollows of the wheels of the wheels because these brushes are always dragged along the common axis. The German utility model with publication number DE 202009011186 U1 describes the operation of a wheel washing apparatus consisting of a main disc 5 of larger diameter which in turn contains three secondary discs of smaller diameter angularly equidistant from each other that rotate independently, in addition to being spinning along with the main disk that drags them in their rotating motion and also houses said secondary discs. 10 In this system, although it incorporates three satellite brushes associated with the secondary discs that rotate independently with respect to the main disc that contains them, said satellite brushes always also rotate in unison along with the said main disc that contains them. This system prevents that none of the satellite brushes can remain in a static position in any of the hollows of the tire of the wheel and therefore the cleaning inside said hollows of the tire will be scarce, and even void. It is also known the patent with publication number US 2013/0333127 A1 which describes the operation of a wheel washing apparatus that has three satellite brushes that 20 manage to make superimposed movements by rotating each satellite brush around its own axis and in addition said satellite brushes they revolve around a common axis. This described system, apart from being expensive and very sophisticated, does not guarantee that the smaller diameter satellite brushes can impact inside the holes that some wheels 25 of the vehicle wheels have for the same reason as mentioned above, where it was described that the secondary brushes do not stop at any time when they are dragged together by the common axis itself. In addition to the limitations and disadvantages of the two systems described in the aforementioned documents, it should be noted that these systems depend on a complete mechanism. This means that to replace any of these wheel washing devices on any machine already installed, it is necessary to assemble the system assembly instead of replacing only one head such as the one described in the invention. 354 Description of the invention In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a head for wheel washing of vehicles comprising a housing where a ring brush and a central axis are fixedly fixed. to which a central brush is attached. Said annular brush defines an internal space where the central brush is housed and also intermediate brushes distributed around the central brush. In one embodiment the housing has a circular shape. The head of the invention further comprises a front disk coupled with insane rotation 10 about the central axis; where said front disk is located within the internal space delimited by the ring brush. The front disc separates two opposing zones: a first zone where the central brush and also the intermediate brushes are located, and a second zone where a transmission mechanism is located that transmits rotational movement to the intermediate brushes fixed to some satellite axes adjusted in tubular junctions integral to the frontal disk. During the rotation of the head the intermediate brushes (5) keep their turns in static positions when they are faced with holes in a wheel of the vehicle wheel to be washed. The transmission mechanism that transmits rotating movement to the intermediate brushes, comprises a conductive sprocket integral with the central axis, intermediate sprockets and driven sprockets; where the intermediate sprockets mesh with the conductive sprocket and with the driven sprockets 25; and where the transmission of movement to the intermediate brushes is carried out independently. The intermediate brushes are arranged in at least one concentric circumferential alignment with respect to the central axis, although preferably they are arranged in at least two different concentric circumferential alignments taking the central axis as reference. Each of the intermediate sprockets meshes with the conductive sprocket and with two driven sprockets that transmit the rotating movement to two5 intermediate brushes located in different concentric alignments. The central axis is connected to the housing by means of a tubular junction end integral with the central axis; wherein said end tubular junction is attached to a removable front disk that is part of said tubular housing. Between the detachable front disk 5 and the front disk a chamber is generated where the transmission mechanism that transmits the rotating movement to the intermediate brushes is housed. The transmission of the rotation from the driving gearwheel to the driven gearwheels is a transmission that increases the number of revolutions. In one embodiment, the intermediate sprockets have a larger diameter than the conductive sprocket 10 and the driven sprockets have a smaller diameter than the conductive sprocket. Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been shown with an illustrative and non-limiting nature. Brief description of the figures Figure 1.- Shows a perspective view of a head for washing vehicle wheels, object of the invention. Figure 2.- Shows a front view of the head of the invention. Figure 3.- Shows a sectional view according to section A-A of Figure 2. Figure 4.- Represents a perspective view of the head of the invention, where essentially a movement transmission mechanism is shown. Figure 5.- Shows another perspective view of the head of the invention. Description of an exemplary embodiment of the invention Considering the numbering adopted in the figures, the head for washing vehicle wheels comprises a circular housing 1 where an annular brush 2 and a central axis 3 bearing a central brush are fixedly attached 4. 30 The annular brush 2 delimits an internal space where the central brush 4 and also other intermediate brushes 5 are arranged arranged in two different concentric circumferential alignments 11a, 11b around the central brush 4. 356 On the central axis 3 a front disk 6 is also engaged with free rotation, also located within the internal space delimited by the annular brush 2; wherein said front disk 6 has tubular junctions 6a where satellite axes 12 are fitted having first ends on which intermediate brushes 5 are fixed, and second ends opposite to the first ends, on which wheels 5 are embedded driven sprockets 7 that engage with other intermediate sprockets 8 and these in turn meshed with a centrally driven wheel 9 integral with the central axis 3. The front disc 6 separates two opposing areas: a first zone where the brush is located 10 central 4 and also the intermediate brushes 5, and a second area where the driven gear wheels 7, intermediate gear wheels 8 and center centered wheel 9 meet. The central axis 3 is integral with an end-shaped tubular junction 3a that is fixed to a cover 15 Detachable front 1a that is part of the housing 1 in which screws 10 are installed that are also used to fix the head assembly zal to a washing machine. In the embodiment shown in the figures, each intermediate sprocket 8 gears 20 with two driven sprockets 7: one that transmits the movement to an intermediate brush 5 located in a concentric circumferential alignment 11a and another cogwheel 7 that transmits the movement to another intermediate brush 5 located in another concentric circumferential alignment 11b. 25 To clean the wheels of a vehicle's wheels, the central axle 3 rotates the central brush 4 and the annular brush 2. The front disc 6 on which the satellite axes 12 distributed in the two concentric circumferential alignments 11a, 11b. 30 With this described arrangement, the cleaning of front holes of the vehicle wheel rims is carried out by means of intermediate brushes 5 strategically distributed in the two concentric circumferential alignments 11a, 11b, so that with this distribution a better coverage is achieved In the whole tire. It should be noted that although in the embodiment shown in the figures the brushes 357 intermediates 5 are distributed in two concentric circumferential alignments, they could also be arranged in more than two and even in a single concentric circumferential alignment. Thus, when the rotation of the central axis 3 is activated, it drags in its movement to the housing 5 next to the annular brush 2 and central brush 4, at the same time that it drags inertia to the front disk 6. In this situation, while There is no contact, apparently, the head assembly will behave like a conventional head. On the other hand, when the intermediate brushes 5 detect friction with the rim, they brake the front disk 10 and the rotating movement transmission mechanism causes the independent rotation of each of the intermediate brushes 5, while the central brush 4 and the annular brush 2 continue spinning normally without stopping. This is achieved with the conductive cogwheel 9 which transmits the rotational movement to the satellite axes 12. 15 The rotation transmission from the conductive cogwheel 9 to the satellite axes 12 where the intermediate brushes 5 are fixed, is achieved by the wheels intermediate sprockets 8 having a larger diameter than the conductive cogwheel 9, thus freeing it from unnecessary stress. In turn, the driven sprockets 7 20 have a smaller diameter than the conductive sprocket 9 in order to subtly increase the speed of rotation of the intermediate brushes 5 with respect to the annular brush 2 and central brush 3. As exerts pressure with the bristles of the brushes on the tire of the wheel of the vehicle 25, the intermediate brushes 5 are penetrating into the hollows of the tire. On the other hand, when the ring brush 2 and the center brush 4 reach the wheel of the vehicle's wheel, they cause the front disk 6 to release slightly from the pressure, causing said front disk 6 to rotate little by little and advance the position. of the intermediate brushes 5, thus decreasing at the same time the speed of rotation of the intermediate brushes 30 and allowing them to rotate at the same revolutions as the central brush 4 and the annular brush 2.
