Definitions

• Support device for the suspension of a roll broom on a sweeping vehicle
• the present invention relates to a support device for the suspension of a roll broom on a sweeping vehicle, comprising a rotary support rotatably mounted on the sweeping vehicle about a vertical pivot axis, a supporting part suspended from the rotary beam via a lifting device comprising a lifting drive and one on the support part a horizontal broom frame, which is mounted so as to oscillate transversely to the axis of rotation of the roll broom.
• Such carrying devices are known from practice be ⁇ . Sweepers in which the roller brushes are suspended by means of corresponding carrying devices are used, for example, within the framework of the so-called black clearance at airports, in which the most complete removal of snow from traffic areas occurs.
• the pendulum-type suspension of the roller broom compensates for local variations in the lateral inclination of the surface to be cleaned and, on the other hand, lateral tilting of the sweeping vehicle when cornering.
• the pendulum position of the broom frame is pretensioned by means of suitable spring elements (eg rubber springs or gas pressure springs) into a zero position.
• roller brush grinds on one side during transport.

• a charac teristic viewpoint of the present invention is thus that the lifting drive of the lifting device engages the locking member and when activating the Huban ⁇ drive to raise the brush unit, the locking member is forcibly operated, namely this ers ⁇ th, pendulum movements of the broom frame enabling Position in his second, the pendulum movement at influence ⁇ lierter position of the broom frame locking position brings. On the way from its first to its second position, the locking member brings the broom frame in its leveled position.
• the lifting drive is deactivated during the turn-up operation (eg by a hydraulic lifting cylinder connected in the floating position), so that the roller brush can follow the surface to be cleaned by means of vertical compensatory movements, then different sideways inclinations of the surface to be cleaned are readily possible and / or different lateral inclinations of the sweeper compensating pendulum movements of the roll broom possible.
• the broom unit can swing freely and without any bias in the floating position determined by the first position of the locking member. In this way it is achieved that even with a substantial lateral inclination of the sweeping vehicle, in particular during cornering with increased speed of the Walzen ⁇ broom rests over its entire length with the same Aufla ⁇ on the surface to be cleaned.
• the locking member is parallel to the axis of rotation of the roller broom horrre ⁇ ckende axis pivoted, and more preferably on the broom frame.
• the point of application of the lifting drive and the articulated articulation of the locking member on the brush frame can be arranged in particular on different sides of the brush frame.
• Such a design is characterized by a particularly high functionality.
• the blocking member in its first position as part of a stop device limits the pendulum movement of the brush frame to a predetermined range. Because by such a double function the locking member of the invention Tragvor ⁇ device comes from a minimum of components. In particular, in this case, it is particularly advantageous if shock-absorbing buffer elements are arranged on the blocking member, which effect at least towards the end of the permissible pendulum motion.
• the locking member is designed as a clamp having two cheeks, which surrounds the articulated connection between the supporting part and the brush frame.

It is particularly favorable if the link parallelogram comprises two double links, wherein the pairs of links of the two double links in each case the support member and the rotary carrier between them aufneh ⁇ . Also, the lifting drive can be arranged in this case between the pairs of handlebars of the two double link, whereby he is accommodated particularly protected. However, a corresponding arrangement of the linear actuator between the rotary carrier and the support member is also advantageous if the Lenkerparallelogramm the Hubein ⁇ direction includes no double link.
