Description
TRUCK BED LINING
Technical field
The present invention relates to a wear-resistant truck bed lining, which is intended for a truck bed subjected to wear, and which has an outer surface arranged to face at least parts of the truck bed, and a wear surface arranged to face material loaded on the truck bed.
Background art
When using a truck for transporting coarse material such as minerals, stones, gravel, sand, clay or the like it is a common measure to line the truck bed with a truck bed lining, which protects the truck bed from abrasive wear typically occurring when material is unloaded from the truck, and impact wear, typically occurring when material is being loaded on the truck, thus making the truck bed more resistant to being damaged by the material transported by the truck. Such a lining may be in the form of sheets or plates that are fastened to the truck bed bottom and side walls, or it may even be sprayed onto the truck bed in a layer of some thickness. A common choice of material is some form of polymer material, such as rubber, or some kind of metal, for instance steel.
However, under certain conditions, some types of materials may tend to stick to the lining to too high an extent. This could for instance be the case when transporting wet or sticky materials, such as clay, wet soil or even snow. In cold weather, there may also be problems of ice being formed between the material and the lining, and in the material itself. This ice may then make the material too difficult to unload. In all of these situations, at least some of the material will stick to the lining and will not be unloaded, a problem which is commonly known as "carry back".
Summary of the invention
It is an object of the present invention to provide a truck bed lining that makes it easy to unload a desired amount of material from a truck, avoiding the "carry back", while still protecting the truck bed and enhancing its wear resistance.
This and further objects are achieved by a truck bed lining having the features as defined in claim 1 , preferred embodiments being defined in the dependent claims.
According to embodiments of the invention, a wear-resistant truck bed lining is provided, which is intended for a truck bed subjected to wear, and which has an outer surface being arranged to face at least parts of the truck bed, and a wear surface being arranged to face material loaded on the truck bed. The wear surface of the lining comprises a polymeric material or a polymeric hybrid material having non-stick properties, such that the lining is arranged to prevent material loaded on the truck from adhering to the lining.
This reduces the "carry back" effect and in turn reduces the fuel consumed by the truck as the truck no longer will transport unwanted material. Further, it reduces the need for cleaning the truck bed as unwanted material will not stick to the truck bed.
The lining may comprise a number of inserts which are arranged such that the friction between the truck bed lining and the material loaded on the truck is lowered. The inserts may for instance be made of a ceramic material or metal, which lowers the friction as well as adds to the wear resistance of the lining.
The polymeric material may be rubber, which has the advantage of being a relatively inexpensive material which is easy to form into a desired shape while still having good wear resistance properties.
The lining may comprise a low friction filler material, such as
polyethylene, which efficiently lowers the friction between the lining and the material loaded on the truck.
The lining may comprise a polymeric material with anti-icing properties, such as a polymeric carbon material lacking polar groups but is polymerized and vulcanized with the aid of a vulcanizing agent comprising peroxides,
sulphur, sulphur derivate or metal oxides ice-preventive rubber, such that the polymeric carbon material is arranged to prevent ice from forming on the lining. When the truck is used in cold weather conditions, this prevents material loaded on the truck from sticking to the truck bed through ice which is formed in the material.
Brief description of the drawings
The invention will now be described in more detail by way of example and with reference to the accompanying schematic drawings, in which:
Fig. 1 is a perspective view of a truck.
Fig. 2 shows part of a truck bed lining having ceramic inserts according to an embodiment of the invention.
Fig. 3 shows a cross section of the truck bed lining shown in Fig. 2. Detailed description of embodiments
A truck bed lining 1 is arranged on a truck bed 2 of a truck 3. In the present exemplifying embodiment an outer surface of the lining 1 is arranged to face a bottom wall 4, side walls 5 and a front wall 6 of the truck bed. The inner, or wear surface 7 of the truck bed lining 1 faces the space on the truck where material to be transported is loaded onto the truck. It may be noted that according to the user's preference more walls of the truck bed may be covered by the truck bed lining , for instance also a back wall 8. It is also possible to cover only the bottom wall 4 with the truck bed lining 1 , or to cover any selection of truck bed walls by the lining, or to leave them bare, as suits the purposes of the truck 3. The truck bed lining 1 may be attached to the truck bed 2 by any means of fastening. It may, e.g., be screwed or nailed to the truck bed 2 or it may be attached to the truck bed 2 using any type of suitable adhesive. Another option is to use some kind of magnetic fastening mechanism. The different means of fastening may also be combined with each other to achieve a properly fastened truck bed lining. Yet another option is to spray the entire truck bed 2 with the truck bed lining material in a fluid form. The truck bed lining 1 is then formed in place on the truck bed 2 as the
spray adheres to the truck bed walls. Further ways of covering the truck bed with a truck bed lining may also be used.
When transporting sticky or wet material on the truck bed 2, this material may stick to the truck bed 2 when unloading the truck. The problem of leaving unwanted remnants of material on the truck bed is commonly known as "carry back". This is a problem, e.g., since the truck 3 then carries around unwanted weight, leading to a higher fuel consumption and in turn higher costs than necessary. It may also be a problem that after unloading the wet or sticky material, the truck 3 might be needed for transporting another type of material, which then could be contaminated by the "carry back". The truck driver may then have to perform cleaning of the truck bed 2, again adding to the costs. The problems may be further accentuated in cold weather, when moisture in the transported material freezes and forms an ice layer or patches of ices mixed with material clinging to the truck bed 2. The problem of ice making the transported material stick to the truck bed can also occur when the truck 3 during winter is used for transporting snow or a snow and ice mixture, which also may include sand or larger pieces of solid material, such as when transporting snow from streets in the main area of a city to a snow dump site in the outskirts of the city.
To avoid the problems associated with material sticking to the truck bed 2, the inventor has realized that not only should a truck bed lining 1 have high resistance to abrasive and impact wear, but it should also include a nonstick material providing a lowered adhesion to sticky or wet materials that in other cases cause a "carry back" effect. The inventive truck bed lining 2 makes it easier to unload these problematic types of material without leaving any larger amounts of the sticky or wet material on the truck. The non-stick properties of the wear surface of the truck bed lining 1 makes it possible for the material transported on the truck to slide off from the truck bed when unloaded without sticking to the truck bed.
The non-stick material may be of different types. In one exemplifying embodiment of the invention, the truck bed lining is made of a polymeric, e.g. a rubber material, interspersed with a number of inserts of another material with a lower friction to the material loaded on the truck than the polymeric
material. One example is inserts made of some type of metal, and another is ceramic inserts, which, apart from giving the truck bed lining an improved resistance to wear, also lessens the adhesion between the truck bed and wet or sticky material loaded on the truck. A plane view of part of such a material is shown in Fig. 2, and a cross-section thereof is shown in Fig. 3, where ceramic inserts 9 are embedded in a rubber material 10. "Embedded" could in this context imply "fully embedded" but generally refers to a situation where one surface of the inserts 9 essentially forms a part of the surface of the lining 1 , while the remainder of each insert 9 is immersed in the rubber 10.
Another option is to use a polymeric material such as rubber which is mixed with a low friction filler material. This low friction filler material may, e.g., be polyethylene.
A further example of a non-stick material which is useful for a non-stick truck bed lining is ice-preventing or anti-ice rubber, which is a material, e.g., described in the document WO92/08767. This material comprises at least one polymeric material comprised of polyolefins or polydienes, i.e. a hydrocarbon rubber material. This polymeric hydrocarbon material also lacks polar groups but is polymerized and vulcanized with the aid of a vulcanizing agent comprised of peroxides, sulphur, sulphur derivates or metal oxides or combinations of sulphur and sulphur derivates. This material has the effect of preventing an ice-layer formed between the material loaded on the truck and the truck bed lining to stick to the truck bed.
Other examples of non-stick materials that may be used in the truck bed lining are polyurethane, polyethylene, or a rubber material having a polyurethane coating on the wear surface. It would also be possible to use, e.g., rubber covered by a layer of polyethylene or other thermoplastic.
