Description
La présente invention est relative à une balayeuse urbaine automobile.The present invention relates to an automobile urban sweeper.
Elle a plus particulérement pour objet un dispositif It more particularly relates to a device
d'aspiration insonorisé pour une balayeuse de ce type. soundproof suction for a sweeper of this type.
Les balayeuses urbaines de ce type étaient, jusqu'à présent, mal insonorisées, quelle que soit leur construction. Les turbines d'aspiration étaient en particulier solidaires des châssis ou des bennes à déchets, ce qui impliquait des générations Urban sweepers of this type were, until now, poorly soundproof, regardless of their construction. In particular, the suction turbines were integral with the chassis or skips, which involved generations
importantes de bruit.noise.
Afin de réduire au minimum ces bruits, il est nécessaire de désolidariser la turbine de la-benne à déchets sur laquelle elle est fixée. Ceci peut être réalisé par l'intermédiaire d'une liaison entre In order to minimize these noises, it is necessary to separate the turbine from the waste container to which it is attached. This can be achieved through a connection between
la benne et la turbine constituée de suspensions élastiques. the bucket and the turbine consisting of elastic suspensions.
En outre, les balayeuses urbaines étaient, jusqu'à présent, montées avec une turbine d'axe de rotation horizontal. Ceci entraîne un effet gyroscopique très important quand la balayeuse amorce un virage. En effet, quand un solide circulaire est en rotation autour de son axe, tout mouvement appliqué audit solide dans lequel l'axe de rotation ne se déplace pas parallèlement à lui-même entraîne un moment In addition, the urban sweepers were, up to now, mounted with a turbine of horizontal axis of rotation. This causes a very important gyroscopic effect when the sweeper initiates a turn. Indeed, when a circular solid is rotated about its axis, any movement applied to said solid in which the axis of rotation does not move parallel to itself causes a moment
gyroscopique tendant a s'opposer à cedit mouvement. gyroscopic tending to oppose said movement.
Ainsi, quand l'aXe-de la turbine de la balayeuse est horizontal, et plus précisément parallèle à l'axe d'avancement de ladite balayeuse, quand un virage est amorcé, le moment gyroscopique engendré tend à ramener la balayeuse dans une trajectoire s'opposant au virage Thus, when the aXe-turbine of the sweeper is horizontal, and more precisely parallel to the axis of advance of said sweeper, when a turn is initiated, the generated gyro moment tends to bring the sweeper into a path s opponent of the turn
amorcé.initiated.
Or, les balayeuses urbaines sont amenées à réaliser de très - Now, street sweepers are brought to realize very
fréquents et brusques virages ce qui pose des problèmes cruciaux de frequent and sudden turns which poses crucial problems of
stabilité lors de ces manoeuvres.stability during these maneuvers.
La présente invention résout ce problème de stabilité grâce a une disposition particulière de la turbine d'aspiration, celle-ci étant The present invention solves this problem of stability thanks to a particular arrangement of the suction turbine, the latter being
désormais montée avec son axe de rotation vertical. now mounted with its vertical axis of rotation.
Par ailleurs, cette position verticale de l'axe de rotation de la turbine n'entraine pas de détérioration des suspensions élastiques sur Moreover, this vertical position of the axis of rotation of the turbine does not cause deterioration of the elastic suspensions on
lesquelles est montée ladite turbine. which is mounted said turbine.

La présente' invention a plus particulièrement pour objet un dispositif d'aspiration pour balayeuse urbaine automobile constituée d'un châssis, d'une turbine d'aspiration,.et d'une benne de collecte des déchets aspirés, la turbine d'aspiration étant d'axe vertical, 2. The present invention more particularly relates to a suction device for an automobile urban sweeper consisting of a chassis, a suction turbine, and a bucket for collecting the waste aspired, the turbine of aspiration being of vertical axis,
