The invention relates to a cleaning vehicle for removing road dirt with a sweeping device, in which a driven roller brush rotates in a receiving housing and this aue one shaft, two fixed on this seated bearing disc and a crane «τβη Rubbing sticks articulated to the bearing washers

exists, according to patent (patent application R 20 371 V /

19b). The main patent values a cleaning vehicle whose roller brush is provided with an automatic compensation for bristle wear through automatic, stepless adjustment of the outer diameter of the roller brush is elastically controlled by centrifugal and spring forces »

moderate · sweeping performance of cleaning vehicles Suffer impairment. Also the possibility of a slackness or a bruise of the spring acting against the centrifugal forces can be a susceptibility to failure bring oneself

In contrast, the invention is based on the object of creating an appliance of the type mentioned, which can aen Kehrwaise while maintaining the automatic compensation of the Borstsnabnutsung is designed in such a way that A transfer of the sound emanating from the unevenness of the sweeping surface and acting on one of its segments Pressure forces on the totality of the bee segments can be excluded and the additional use of a spring tension can be dispensed with.

According to the invention, this object is achieved by that the main brush is automatically adjustable in its outer diameter and the individual brooms in their respective Working position are held adamant. In the case of a particularly expedient design, the single arms can be double-armed by means of holding arms Levers are hinged to the warehouse receipts, the inner ones Lever arms find each other with their free brace on the adjacent lever arms and all arms during the adjustment of the outer diameter of the main brush remain positively connected. particularly expediently in the form of a bevel! Advantageously, one support surface of the inner Lever arms can be curved and designed as a slideway for the adjacent free land of the adjacent arm. An extremely stable mounting of the holding arms can * be achieved in that the bearing washers are double-walled and the hinge pins of the holding arm are mounted with both ends in the pane walls *

The drawing illustrates the invention, for example, in one embodiment of the elements of the same

FIG. 1 shows the shaft of a turning wheel formed according to the invention with bearing washers fixed thereon and the type of articulation of the holding arms in a longitudinal section ; and FIG.

Herein 22 designates the roller brush shaft. Are on her two bearing washers 24 fixed and non-rotatable and arranged to which the holding arms 26 of the brooms 21 are rotatably attached by means of a pivot pin 23 each while the Lagereoheiben 24 double-walled, e.B. U-shaped in cross section, and the Uelenkbolsen 25 of the holding arms 26 mounted on both sides in the walls of the soles 24. The holding arms 26 are double levers auegebilden, with the outward-facing lever macaws on their free inde with one broom segment 21 each are connected, the inner lever arms 26 support each other - and ensure an unyielding adjustment of the respective outer Durohmeesers of the orphan. " In the embodiment shown, the two arms of the holding arms 26 close an angle of approximately 135 ° a. In addition, the holding arms 26 are so articulated that that the single broom 21 is approximately tangential in the dl · dem Direction of rotation of the Kehrwell · 22 geeetet · Direction to protrude.

In the circular arrangement of the holding arms 26 on the Lagereohiben 24 acts «loh dl · when the rotary brush acts on the holding arm · 26« centrifugal force acts on the mobility of the holding arms 26 in such a way that 41 «« β «sioh just like one according to the progressive Abnutsung the Boretenepit «en 15 can erect and in

the respective work position, bracing against each other, are adamant. Due to the progressive wear of the bristle tips 13, the erection of the initially strongly angled outer lever arms 26 increases continuously and the strength of the centrifugal forces acting on the holding arms 26 both due to the reduction in bristle mass and the increasing radial position of the holding arms 26. The curve of the sliding surface 26 ⁵ It = t chosen so that the. inner lever arms 26 are constantly connected in a form-fitting manner, remain and form a closed king

A cleaning vehicle designed according to the -rfindune has the advantage that with just one means a Reliable automatic self-adjustment of the main brush is guaranteed and the steps and movements acting on the line segments and movements cannot be transferred to all other segments. This will not only a substantial increase in the life of the Kenrwaleenteile but also achieved an advantageous reduction in the motor power required to drive the orphan.
