Definitions
- the present invention relates to a suction device intended to be used on articulated public road vehicles, such as, for example, street sweepers.
- Vehicles of this type consist, for the most part, of a chassis articulated, having at least two axles and to which can be connected cleaning means such as brushes or brooms, means suction, a receptacle for receiving the sucked residues, possibly a water tank of sufficient capacity and a station of ordered.
- cleaning means such as brushes or brooms
- suction means suction
- a receptacle for receiving the sucked residues, possibly a water tank of sufficient capacity and a station of ordered.
- the chassis is actually composed of two half-chassis, the front part receiving the suction means and the rear part receiving the tank and the motorisation elements.
- the suction means comprise a suction turbine and means for the collection and transfer of waste aspired receptacle,
- suction means are most often made of one or several pipes connected to suction nozzles.
- a depression is created inside the receptacle.
- the waste is generally moistened just before aspiration, to facilitate their transfer to the bottom of the tank. This allows to link them and to avoid a dust discharge through the turbine.
- the lower part of the suction duct is connected to the frame front of the vehicle by its nozzle, which is arranged so as to collect the waste collected on the front or on the sides by the brooms or brushes.
- the receiving tank is mounted on the rear part of the chassis.
- the suction pipe is therefore subject to the various constraints that arise from the articulation between the two parts of the chassis.
- road vehicles are very dependent on the configuration and the congestion of the tracks on which they move. They have to make turns frequent and abrupt, and high-amplitude steering movements, for example to avoid an obstacle or bypass a vehicle parked along a sidewalk.
- the suction pipes are therefore exposed to shocks and repeated constraints, and their life is greatly limited.
- bent parts undergo a strong abrasion under the effect of sand and granular waste aspired, resulting in very high wear fast.
- the invention proposes to remedy these various drawbacks by realizing a suction device comprising a completely straight duct between the two parts of the chassis.
- a rectilinear conduit is illustrated in DE 25 41 108, which describes a road vehicle comprising pneumatic suction means, comprising a straight suction duct, one end of which is attached to a waste receptacle located at the rear of the vehicle, and the other end is terminated by an enlarged part directed towards the ground, to increase the suction area.
- the proposed solution is also not fully satisfactory because it can not be transposed to an articulated vehicle, as long as the duct suction is here made in one piece, which imposes that its bottom end is free, unable to be secured to the front of the vehicle.
- the device according to the invention comprises a conduit in two elements, each element being totally attached to the part of chassis to which it is connected, the two elements also covering means at their respective free ends.
- FIG. in accordance with the present invention, which is referred to as general (1), is mounted on the chassis (2) of a road vehicle.
- the frame (2) is composed of a front part (12) and a rear part (22), interconnected by a hinge (3) of any type.
- the suction means (not shown) are arranged under the part before (12).
- the receiving tank (4) of the sucked waste is mounted on the rear part (22).
- a suction duct (6) connects the front portion (12) and the rear portion (22).
- the ends (16 and 26) of the duct (6) are integral respectively with the tank (4) and the front portion (12) of the frame (2).
- the end (16) of the duct (6) covers an orifice formed in correspondence in the wall of the tank for the passage of waste aspirated.
- the duct (6) consists of two distinct elements (7 and 8).
- each of the two elements (7 and 8) comprises a flange flange-shaped (9).
- the flanges will be substantially oval.
- the two elements (7 and 8) forming the duct (6) are arranged end-to-end, in the axis of the articulation of the chassis of the vehicle, and the end collars (9) of each of the parts are arranged against each other.
- the rotation of the flanges (9) does not affect the tightness of the device, nor the overall position of the duct which remains substantially rectilinear. Indeed, the oval shape of the flanges forming the flanges (9) ensures a minimal but constant recovery, even in the steering position full. During suction, the collars are plated against each other the other, which ensures the sealing of the device.
- the width of the collars (9) makes it possible to make up for the offset in ellipse between the two elements (7 and 8) when the vehicle steers.
- suction device is not limited to the shape of realization described above, and may receive any variant without it is outside the scope of the invention.
- the dimensions of the ducts may be arbitrary.
