Brush construction for motor vehicle washing systems

Abstract

The invention relates to a brush construction for a motor vehicle washing system comprising a base plate (2) supporting a plurality of bristles (3), each bristle having a base end (31) and a free end (32) secured to the plate (2) ); the substrate (2) is adapted to be removably fixed on a rotating configuration suitable for rotating the substrate (2) around its central axis; the bristles (3) are fixed on the substrate (2), both radially, inwardly and outwardly, also non-radially, clockwise and counterclockwise with respect to the direction of rotation of the substrate (2) or in any other direction different from the above-mentioned directions; the bristles (3) are provided with mutual convergence and / or Or spread out the tilt direction.

Description

technical field [0001] The object of the invention is a brush construction for a motor vehicle washing system. Background technique [0002] Car washes are known to include a series of rotating brushes of different shapes and sizes suitable for cleaning different parts of the vehicle. [0003] For cleaning the wheels, brushes with a circular base rotating along a horizontal axis are provided, which reach each wheel of the vehicle. [0004] Brushes for rims currently in use comprise bristles arranged axially on a base plate which rotates about its central axis. [0005] The bristles can be angled radially outwards, providing the brush with a frusto-conical shape to increase the active surface relative to the periphery of the substrate, which is of standard size to fit into current motor vehicle washing systems. [0006] Figure 11 An example of a standard installation providing a conventional type of brush is shown. [0007] The brushes work together with high pressure wat...

AI Technical Summary

Problems solved by technology

[0009] For several years, motor vehicles have often been equipped with spoked wheels, which are difficult and incomplete to clean with automatic rotating brushes

[0010] In fact, the bristles of the brushes currently in use do not effectively reach the sides of the spokes of the wheel, and it is necessary to clean each spoke manually if the vehicle is to be perfectly washed

[0011] Brushes with multiple discs are also not fully effective in cleaning spoked wheels and in all cases using brushes with multiple discs constitute a high cost not commensurate with the results achieved
