Definitions

  • the present invention relates to a sweeper for sweeping traffic areas with at least one front axle and one rear axle and a rotating sweeper roller arranged between them and pivotable about a vertical axis.
  • Such a sweeper is known from DE-OS 35 26883. It has a sweeping roller arranged approximately in the center of the vehicle, which is driven in such a way that it rotates with the direction of rotation opposite to the vehicle wheels.
  • the sweeper roller is the vehicle's longitudinal axis inclined; this sweeps the sweepings to the side and ejects them under the sweeper.
  • Sweepers of this type are often equipped with a snow plow mounted on the front and used for snow removal if a complete and residue-free removal of the snow from the traffic area (black clearance) is to be achieved.
  • black clearance is for example for the runways of. Airports required.
  • the sweeping rollers In order to enable economical snow removal in such extensive traffic areas, the sweeping rollers have a large length, which results in a correspondingly large sweeping width of the inclined sweeping roller. In such sweepers the problem arises that a subset of the swept by the sweeping roller
  • the present invention is therefore based on the object " to create a generic sweeper in which, even when using sweeping rollers of large speed and when operating at high speeds, an undisturbed discharge of the swept material to the side is possible without the maneuverability being thereby of the vehicle is deteriorated.
  • this object is achieved in that the sweeper is divided into a front unit built on the front axle and a rear unit built on the rear axle, which are connected to one another by means of a telescopically variable-length connecting unit bridging the sweeping roller, so that the wheelbase of the vehicle can be changed with it.
  • the lengthened wheelbase according to the invention enables clearing with very large sweeping widths and high clearing speeds, in particular in the case of straight traffic areas such as, for example, at the runways of airfields, while avoiding the disadvantages of known sweeping vehicles; With such a clearing operation, it is not a question of a particularly good maneuverability of the sweeper. on the other hand can be close Räumabête such as evacuation in the Vorfeld ⁇ and when turning at the ends of runways according to the invention with a shortened sweeper and t l_ei a relatively low speed Räumge ⁇ cleared, so that the above beschrie ⁇ surrounded disadvantages are reliably avoided.
  • the minimum wheelbase can be selected to be even smaller than is the case with known sweepers with a fixed wheelbase, since the latter have to meet average requirements with regard to maneuverability and sweeping speed.
  • the sweeper according to the invention has a maximum shortened wheelbase for slow sweeping a higher maneuverability than known sweepers.
  • connection unit can be changed longer, ie can be lengthened and shortened, while the sweeper is traveling. In this way, the operator of the sweeper can shorten the wheelbase for sending the sweeper, for example when the end of the runway is reached, without the sweeping operation having to be interrupted. This makes sweeping particularly economical.
  • the length of the connecting unit is particularly preferably changed hydraulically. The advantages of such a hydraulic control of the wheelbase are, in addition to the low maintenance requirements, the high flexibility with regard to the control and automation options as well as other advantages known for hydraulics.
  • at least one hydraulic telescopic cylinder assigned to it is preferably provided.
  • connection unit can also comprise additional guide parts which have suitable longitudinal guides.
  • the sweeping roller is preferably suspended on the sweeping vehicle by means of a rotary bearing so as to be pivotable about a vertical axis.
  • the side to which the dirt is ejected, as well as the ejection angle can be selected in accordance with the present conditions.
  • the angle between the sweeping roller and the longitudinal direction of the vehicle can be selected to be correspondingly acute are so that the side-facing component of the force exerted by the bristles of the sweeping roller on the sweepings is increased.
  • the sweeping roller which can be pivoted about a vertical axis is particularly preferably suspended on the connecting unit, such a suspension being particularly advantageous in which the suspension point can be displaced in the longitudinal direction of the vehicle.
  • the longitudinally movable suspension of the sweeping roller can interact with the further preferred feature that the connection unit can be extended at least to such an extent that the clear width between the front unit and the rear unit corresponds approximately to the length of the sweeping roller, which is pivoted below the outline of the vehicle and, if appropriate, aligned exactly in the vehicle longitudinal direction when the suspension point is chosen in the middle between the front unit and the rear unit.
  • This possibility of swiveling the sweeper roller completely under the vehicle outline also allows the passage of relatively narrow garage doors, passages etc., even though the sweeper vehicle has a sweeper roller whose length, for example, exceeds twice the vehicle width .
  • the length of the sweeping roller does not hinder the passage of narrow passages, the usability of the sweeping vehicle according to the invention is thus improved compared to the known sweeping vehicles.
  • the connecting unit comprises a frame part rigidly connected to the rear unit and a telescopic part installed between the latter and the front unit.
  • Sweeping roller is suspended on the frame part after the weight of the sweeping roller with a corresponding weight distribution within the rear unit predominantly acts on the rear axle in this way.
  • axles on the front and on the rear unit is chosen in accordance with requirements; within the scope of the present invention, it is of no fundamental importance.
  • the front unit of the sweeping vehicle according to the invention preferably has at least one driven axle, a hydrostatic vehicle drive acting on the wheels of the or at least one rear axle being provided. Since only hydraulic lines n, for example hoses, are required for the transmission of the aluminum drive power from the front unit designed as a drive head to the rear unit comprising the hydrostatic drive, the variable length of the connection between the front unit and the rear unit does not pose a problem for the power transmission ,
  • the hydrostatic vehicle drive also has advantages with regard to the infinitely variable variability of the drive torque and the driving speed over a wide range.
  • a hydraulic motor which is connected to the hydraulic supply provided in the drive head, is also particularly preferably provided for driving the sweeping roller.
  • the coupling of the rotational speed of the sweeping roller to the driving speed of the sweeping vehicle can be achieved with particularly little effort by means of corresponding hydraulic controls.
  • the hydraulic motor can be flanged directly to the sweeping roller or, for example, arranged above it; in the latter case, for example, a chain, a toothed belt or the like can be used to transmit the torque.
  • a separate drive unit for the sweeping roller is provided in the rear unit of the sweeper. This is particularly useful if very high drive powers are used to operate the sweeping roller are necessary, such as in the case of particularly large sweeping rollers and / or for sweeping particularly heavy sweepings.
  • the power can also be transferred hydraulically from the drive unit to the broom; Likewise, mechanical means such as shafts, chains, etc. are suitable for transmitting the drive power, particularly when the sweeping roller is not longitudinally displaceable.
