A headpiece for washing vehicle wheels, characterized in that it comprises: - a housing to which an annular brush is solidly fixed and a central axis joined to a central brush; where the annular brush defines an inner area housing the central brush and also intermediate brushes that are distributed around the central brush; - a frontal disc coupled with idle rotation around the central axis; where said frontal disc is located inside the inner area defined by the annular brush; and where said frontal disc separates two opposite areas: a first area where the central brush and the intermediate brushes are located, and a second area containing a transmission mechanism that transmits rotational movement to the intermediate brushes fixed to satellite axes secured to tubular junctions connected to the frontal disc; where, as the headpiece rotates, the intermediate brushes continue rotating in their fixed positions when they are facing the gaps in the wheel rim of the vehicle being washed; wherein the transmission mechanism that transmits the rotational movement to the intermediate brushes comprises a lead cogwheel connected to the central axis; intermediate cogwheels and follower cogwheels; where the intermediate cogwheels interlock with the lead cogwheel and the follower cogwheels, and where the transmission of movement to the intermediate brushes is carried out independently, and; the intermediate brushes are arranged in at least two different concentric circumferences, in relation to the central axis. - a housing to which an annular brush is solidly fixed and a central axis joined to a central brush; where the annular brush defines an inner area housing the central brush and also intermediate brushes that are distributed around the central brush; - a frontal disc coupled with idle rotation around the central axis; where said frontal disc is located inside the inner area defined by the annular brush; and where said frontal disc separates two opposite areas: a first area where the central brush and the intermediate brushes are located, and a second area containing a transmission mechanism that transmits rotational movement to the intermediate brushes fixed to satellite axes secured to tubular junctions connected to the frontal disc; where, as the headpiece rotates, the intermediate brushes continue rotating in their fixed positions when they are facing the gaps in the wheel rim of the vehicle being washed; wherein the transmission mechanism that transmits the rotational movement to the intermediate brushes comprises a lead cogwheel connected to the central axis; intermediate cogwheels and follower cogwheels; where the intermediate cogwheels interlock with the lead cogwheel and the follower cogwheels, and where the transmission of movement to the intermediate brushes is carried out independently, and; the intermediate brushes are arranged in at least two different concentric circumferences, in relation to the central axis. a first area where the central brush and the intermediate brushes are located, and a second area containing a transmission mechanism that transmits rotational movement to the intermediate brushes fixed to satellite axes secured to tubular junctions connected to the frontal disc; where, as the headpiece rotates, the intermediate brushes continue rotating in their fixed positions when they are facing the gaps in the wheel rim of the vehicle being washed; wherein the transmission mechanism that transmits the rotational movement to the intermediate brushes comprises a lead cogwheel connected to the central axis; intermediate cogwheels and follower cogwheels; where the intermediate cogwheels interlock with the lead cogwheel and the follower cogwheels, and where the transmission of movement to the intermediate brushes is carried out independently, and; the intermediate brushes are arranged in at least two different concentric circumferences, in relation to the central axis.
