Definitions

• the present invention relates to the field of waste collection bins provided with wheels.
• These collection bins generally comprise a plastic tank, possibly equipped with a pivoting lid, at the bottom of which are mounted wheels, usually through the addition of an axle.
• a wheel 1 generally comprises a hub 2 of plastic, intended to be mounted on an axle or an axle, the hub 1 being integral with a sail forming a rim 3 on which is mounted a bandage 4.
• the peripheral surface of the tire generally made from rubber (possibly recycled) forms the tread of the wheel.
• the collection bins are daily moved and handled during collection operations. Their movement on the sidewalks and the roadway (and in particular, if necessary, the descent of the sidewalk towards the roadway) cause shocks and vibrations which are responsible for the noise of the ferry.
• This noisy appearance of wheeled bins is reinforced by the fact that, to ensure robustness and sufficient longevity to the wheels, the bandage is generally a solid and thick element, which makes it very little deformable, even when it is made in a rubber-based material.
• the tire is therefore little damping and transmits to the vessel tank, without damping or almost shock and vibration it undergoes, through the rim and the hub which are generally very rigid.
• the almost complete transmission to the rim and hub vibrations and shocks received by the bandage can also lead to the destruction of the latter, in case of extreme and / or repeated solicitations.
• the object of the present invention is to overcome the drawbacks of existing solutions by proposing a wheel band and a wheel for a collection tank making it possible to drastically reduce the noise generation during driving, but also to reduce the weight of such a wheel. as well as the quantity of material necessary for its manufacture.
• the invention relates to a tire wheel intended to be mounted on a wheel rim of a waste collection tank, said tire being of generally annular shape and comprising:
• an inner belt carrying a contact surface with the rim carrying a contact surface with the rim; the contact surface being formed by the surface surrounding the apices of a plurality of ribs extending radially projecting from the inner belt of the tire.
• the inner belt carries a central core extending radially projecting from the waistband, and to which the ribs are connected.
• the ribs are disposed on either side of the central core.
• the opposing ribs located on either side of the central core, face each other in pairs.
• the opposing ribs located on either side of the central rib are interdigitated.
• the radially inner surface of the core is not merged with the contact surface.
• the outer belt and the inner belt are connected to each other by an intermediate portion having a plurality of ribs.
• the ribs are interconnected so that they form an integral intermediate portion.
• the intermediate portion has a general sinus shape.
• the bandage according to the invention is obtained by molding, in particular by molding a material resulting from the recovery of tire grinding residues.
• the invention also relates to a garbage collection container wheel, comprising a hub integral with a rim and a wheel tire as defined above.
• the wheel tire is tightly mounted on the rim.
• FIG. 2 is a perspective view of a wheel tire according to the invention.
• FIG. 3 is a half-view from the side of the wheel tire of FIG. 1;
• FIG. 4 is a broken section with intersecting planes AA of the tire of FIG. 3.
• FIGS 2 to 4 show a bandage according to the invention, obtained in one piece by molding.
• the wheel tire 10 has a generally annular shape of axis XX.
• the tire 10 comprises a radially inner belt 12 and a radially outer belt 14, connected to one another by an intermediate portion 16.
• the wheel tire 10 is designed to be mounted by elastic clamping on a wheel of waste collection tank.
• the outer belt 14 has a radially outer surface which forms the running surface 18 of the tire 10.
• the profile of the running surface 18 is flat, but any other type of profile can of course be considered (convex profile, presence of striations and / or sculptures, etc.)
• the inner belt 12 is intended to be tightened, by elastic deformation, on the outer surface of a rim.
• the inner belt 12 carries for this purpose a radially inner surface which forms, when the tire is mounted on a rim, a contact surface 20 with the latter.
• the contact surface 20 is adapted to cooperate with the profile of the rim provided for carrying the wheel tire.
• the tire of Figures 2 to 4 is intended to be mounted on a rim having on its radially outer portion a concave circular profile, for example substantially similar to the profile of the rim of Figure 1.
• the inner belt 12 and the outer belt 14 are integral with each other, being connected by the intermediate portion 16, this portion may be solid or as detailed below, formed by a lightened structure such as a network of ribs .
• the contact surface 20 of the inner belt 12 is formed by at least a portion of the ridges of a plurality of ribs 26, 28 disposed on either side of a central core 22.
• the central core 22 and the ribs 26, 28 extend radially with respect to the axis XX of the tire 10, projecting from the inner belt 12.
• the ribs 26, 28 are distributed uniformly about the axis XX, being spaced apart from one another a constant angular interval. In addition, these extend in an axial direction (parallel to the axis XX) from the inner surface 24 of the central core 22, to which each rib 26, 28 is connected.
• the ribs are further arranged so that their largest dimension is oriented according to a direction parallel to the axis XX.
• the ribs 26, 28 face each other in pairs, but it may be preferred that the ribs are offset, and in particular interdigitated. A different number of ribs on either side of the central core may also be preferred.
• each rib 26 28 is decreasing in the axial direction, from the central core to each respective edge of the inner belt 12.
• the portion the peak of each of the ribs which is contained in the contact surface 20 has a circular profile.
• each rib has a decreasing section from the base to the top (for example a substantially triangular or trapezoidal section), which facilitates the demolding operation.
• the radially inner surface 24 of the central core 22 is in the flat profile example.
• This inner surface 24 does not participate in the contact between the tire 10 and the outer surface of the rim.
• This flat profile here constitutes a clearance relative to an entire circular profile, which facilitates the adjustment of the wheel tire 10 on the rim, the latter being mounted loosely tightened.
• other profiles may be preferred for the inner surface of the core 22.
• the tire is able to deform and absorb a large part of the shocks and vibrations it undergoes instead of transmitting almost completely to the rim and the hub.
• the non-full realization of the inner part of the bandage makes it lighter, for a mechanical strength equivalent to solid bandages known.
• the cushioning quality of the bandage can be further enhanced by a suitable constitution of the intermediate portion 16, which secures the inner belt 12 and the outer belt 14.
• this intermediate portion 16 has a plurality ribs 30 joining the outer belt 14 to the inner belt 12.
• the consecutive ribs are connected in pairs, thus forming a single ribbed structure, in the example in the general form of sinuses or waves.
• the intermediate portion has a general shape in waves whose peaks and valleys are located on either side of the median radial plane of the tire (plane perpendicular to the axis XX). This structure has the advantage of being very efficient in terms of cushioning and be particularly light, while having the required mechanical strength.
• the wheel band according to the invention has the advantage of constituting a lightweight structure, resistant and having the desired deformation and cushioning qualities. It is also perfectly suited to molding production in one piece.
• the bandage according to the invention may be molded from a recovery material, such as a material resulting from the recycling of used tire grinding residues (such as for example the material known under the name of "poudrette"").
• the thickness of the various ribs which the bandage is provided with will be provided to be greater than the maximum size of the grains contained in the material after processing.
• the wheel tire according to the invention thus makes it possible, as explained above, to obtain better impact cushioning, better vibration absorption than the known tire, thus promoting the longevity of the wheels provided with this tire. , while allowing to reduce the noise nuisance generated by the collection bins.
• the hub provided with a tire according to the invention undergoes less stress, which allows to extend the life of the hub.
• the bandage itself is better preserved over time, thanks to its ability to absorb some of the shocks and vibrations it undergoes.
• the structure of the band according to the invention allows a significant weight gain and a significant decrease in the amount of material required for its manufacture.
• the wheel tire according to the invention is particularly suitable for manufacturing by molding, in particular by molding a material resulting from the recovery of waste tire grinding residues.
