A rotating brush for a vehicle washing system, includes a shaft (2) rotatable about a rotation axis (20) thereof and a first annular support means (31) surrounding a first section (21) of said shaft (2) and including a first group (310) of longitudinal seats. The first support means (31) extends along the rotation axis (20) between a first and a second base (316, 317). A first direction (318) of travel of the first group (310) of longitudinal seats is defined by the first towards the second base (316, 317), and each of the longitudinal seats of the first group (310) includes a first and a second end (312, 313). A first set (41) of cleaning elements is engageable in the first group (310) of longitudinal seats.

A surface cleaning apparatus comprises a brushroll that rotates about an axis. The brushroll defines a cylindrical portion and the axis extends centrally through the cylindrical portion. The brushroll also includes a rib that extends in a direction away from the axis. The rib includes a face extending along a line that is collinear with a secant through the cylindrical portion. A brush member extends from the face.

A wash apparatus for a vehicle wash installation is provided, which includes a shaft drivable in rotation about a rotation axis and wash elements operatively connected thereto. In order to be able to adapt to the contour of a vehicle, the wash apparatus can be divided axially in two or more wash apparatus segments and that the at least one wash apparatus segment includes a wash element holding body having wash elements held thereto, said wash element holding body defining a wash apparatus segment axis which is different from the rotation axis, and a gear device which couples the shaft to the wash element holding body in order to rotate same about the wash apparatus segment axis, wherein the wash element holding body is configured for pivotal movement relative to the shaft via the gear device. Furthermore, a vehicle wash installation including a wash apparatus is provided.

The present invention provides a roll shaft having high corrosion resistance and rigidity against bending, and a brush roll comprising the roll shaft. The roll shaft 2 is for use in a brush roll 1 for brushing a strip of metal sheet. The roll shaft includes: a shaft body 7 to which multiple annular discs 4 having multiple brush bristles 5 implanted around the outer peripheral edge of the discs 4 are attached; key bases 8 attached to recessed grooves 72 provided on the outer peripheral edge of the shaft body 7, the key bases comprising keyways 80 into which insertion members 6 projecting from the inner peripheral edge of the annular discs 4 are fitted, and the key bases 8 comprising a corrosion-resistant metallic material, a corrosion-resistant alloy, or a corrosion-resistant resin material.

A cleaning roller is mountable to a cleaning robot. The cleaning roller includes a sheath comprising a shell, an outer diameter of the shell tapering from a first end portion of the sheath and a second end portion of the sheath toward a center of the roller. The cleaning roller further includes a core including a central portion interlocked with the sheath to rotationally couple the core to the sheath and inhibit relative translation of the sheath and the core along an axis of rotation. An inner surface of the sheath and an outer surface of the core define an air gap therebetween, the air gap extending from the central portion of the core longitudinally along the axis of rotation toward the first end portion or the second end portion.

A rotary brush for processing the surface of a vehicle includes a rotary brush main part and a plurality of fill material holders that are arranged on an outer lateral surface of the rotary brush main part spaced apart from one another in the circumferential direction thereof. Each fill material holder can be secured to the rotary brush main part in a plurality of stop positions spaced apart in the radial direction of the rotary brush main part.

A gantry style car wash assembly is disclosed. The car wash assembly has two opposing support pillars, a transverse gantry member, first and second opposed wall segments, and a brush mounted about a shaft. The transverse gantry member extends between the two opposing support pillars, and is moveable up and down relative to said two opposing support pillars. Each of the first and second opposed walls defines a portion of two opposing channels. The first and second removable wall segments are removably mountable above the first and second wall segments. Each wall segment includes a vertical extension channel that extends one of the two opposing channels substantially to said transverse gantry member. The brush extends between said first and second pillars, and that is mounted within said two opposing channels for upward and downward movement of said brush.

A device for cleaning or precision machining of workpieces comprises a housing; a central roller having two ends supported by means of rotary bearings on carriers fixed on the housing; a first roller having a first end connected to one of the carriers by a joint and having a second end supported by means of a rotary bearing; a second roller having a first end connected to another one of the carriers by a joint and having a second end supported by means of a rotary bearing; a drive motor for rotatingly driving the first and second rollers and the central roller for treating a workpiece; a suction device for removing particles from the rollers; and at least a first and a second pinion gear coupled to the first and second rollers for angularly adjusting the first and second rollers with respect to said central roller.

The invention relates to an apparatus for cleaning surfaces, in particular of solar collectors and/or of photovoltaic installations, having at least one cleaning member, in particular a brush roller or plate brush, moving, in particular rotating, during the cleaning operation, having a holding device for the cleaning member, having a fluid drive for the cleaning member operable in different states and having a switching device with which a change can be made between the different operating states of the fluid drive.

A cleaning element to be fastened on a cylindrical basic body has a longitudinal axis and is designed as a cylindrical hollow element and comprises a skeleton and a spiked lattice stretched on the skeleton. The skeleton is connected to the spiked lattice by means of a rubber sealing compound, and an inner surface of the cleaning element facing the longitudinal axis is formed by the skeleton or the rubber sealing compound. The skeleton is formed by support rings which are arranged at certain intervals concentric with the longitudinal axis and which are held by means of one or more webs extending in the direction of the longitudinal axis.
