Definitions
- the invention relates to a vehicle rim, a method for the production thereof and the use of the vehicle rim.
- Rims are important components of modern motor vehicles. Together with the choice of tire material, they have a not insignificant impact on the stability, safety and ride comfort of the vehicle. The desire for increasingly sophisticated vehicle designs leads to an unmanageable variety of wheel types.
- the rims can sometimes differ significantly in their size and design from each other.
- rims are usually made of a metallic material. The use of metal gives the rim the necessary stability.
- the high stability of the rim is associated with a high weight depending on the metal used, usually steel or aluminum.
- an attempt is also made to reduce the weight of the rims.
- the weight saving for extending the range of the vehicle is an important topic. This is possible in part through the use of lighter metals or lighter metal alloys.
- these materials often cause corrosion problems, stability problems and sometimes significant ones compared to conventional steel
- EP 1 479 533 A2 discloses a vehicle wheel with a metal-free plastic rim and a built-in pressure sensor. The rim and tire are permanently connected over the wheel life in the disclosed arrangement.
- US 4,896,922 discloses a vehicle wheel having a solid plastic rim body made by an injection molding process. At the cylindrical
- the rim body is made of halogen-free polypropylene copolymer.
- US 2005/0269866 A1 describes a rim arrangement with a metallic rim well, in particular made of aluminum or steel, and semi-transparent
- the central component of the rim assembly may be made of polycarbonate.
- DE 2 157 090 A1 describes a vehicle wheel consisting of a body and a rim base, which in one piece of a cellular rigid
- Plastic core material are formed.
- a reinforcing element may be embedded in the body with a central hub.
- the plastic core material is covered by a skin made of a high-strength plastic material.
- the object of the invention is a rim for a vehicle
- the inventive rim for motor vehicles comprises at least one inner metal ring 1 with a central hub connection opening 6 and two to ten, preferably four to six screw holes 7.
- inner metal ring in the context of the invention comprises a cylindrical body with two
- the inner metal ring has a preferably likewise cylindrical, preferably continuous
- Hub connection port 6 on.
- This hub connection port 6 receives the wheel hub of the vehicle and ensures the fixation of the rim and the Rades on the vehicle.
- the attached to the hub connection opening two to ten screw holes 7 attach the rim via corresponding screws on the wheel hub of the vehicle.
- From the inner metal ring 1 run three to ten metallic spokes 2 to the outside and terminate in a circumferential outer metal ring 3.
- Metal composite body of inner metal ring 1, metallic spokes 2 and circumferential outer metal ring 3 ensures high stability within the rim.
- a polycarbonate sheath 4 surrounds the metallic spokes 2 and the outer metal ring 3.
- the polycarbonate sheath 4 may contain further polymers in the form of a melted mixture and / or copolymers. The polycarbonate sheath 4 sits beyond the outer
- the polycarbonate body may for example consist of two half-shells, which are welded or glued together at their parting surface, including the metallic composite body.
- the metallic composite body can also be arranged overall in one of the two half-shells. Both half-shells are preferably made of the same polymer, preferably of polycarbonate.
- the polycarbonate sheath 4 preferably has an averaged optical
- the polycarbonate sheath 4 preferably comprises one or more light fields.
- the light fields can reflect incident light to the outside and thus enable a glow of the polycarbonate sheath.
- the light fields preferably comprise particles, dot matrix,
- the polycarbonate sheath 4 preferably comprises outside or inside the two half-shells forming the rim LEDs (Light Emitting Diodes) or OLEDs (Organic Light Emitting Diodes).
- the LEDs or OLEDs allow one
- the polycarbonate sheath 4 partially or completely fills the gaps between the spokes 2.
- the term “partially” also includes cutouts or thinner sections within the meaning of the invention
- the polycarbonate sheath preferably comprises polyethylene, polypropylene, polystyrene, polyurethanes, polymethylmethacrylates, polyacrylates, polyesters,
- Polyamides polyethylene terephthalate and / or mixtures or copolymers thereof.
- it consists of polycarbonate blends such as
- the polymers mentioned can be melted down together with the polycarbonate to the Polycarbonatummantelung or used as copolymers.
- the inner metal ring 1, the outer metal ring 3 and the metallic spokes 2 may contain aluminum, titanium, iron, chromium, vanadium, cobalt, nickel, tungsten and / or alloys thereof, and are preferably made of steel or aluminum.
- the adhesive surface of at least one of the half shells contains acrylate adhesives, methyl methacrylate adhesives, cyanoacrylate adhesives, polyepoxides, silicone adhesives and / or silane crosslinking polymer adhesives, polyurethanes, and mixtures and / or copolymers thereof.
- the half-shells themselves are preferably made of polycarbonate or one of the polymers mentioned above, as far as these conditions of strength, impact resistance and the
- the invention further includes a method for producing a rim, wherein in a first step, a base half shell, preferably made of polycarbonate, injection molded. Subsequently, the metal composite from the inner
- Metal ring 1 with a central hub connection port 6 and
- the second (upper) Haibschaie can be welded or glued as a prefabricated half shell with the base half shell.
- the upper half-shell can be applied in liquid form as a polymer melt on the base half-shell and the
- the two half shells are preferably produced by means of an injection molding process.
- Metal ring 3 including the rim 5 made.
- a particularly advantageous method for the production of the rim consists in the use of so-called two-component injection molding (two-component injection molding).
- two injection units work together in succession with one and the same mold part (closing mold), after which
- the closing mold is supplied, for example by means of the turning plate technology of the second injection unit. After the first half-shell of the rim is made with the inserted metal composite in the first injection unit, it is together with the closing mold the second injection mold fed.
- This injection mold has here the shape of the second half-shell. In the injection molding process, the second half-shell is sprayed onto the first half-shell.
- Injection units different polymers are processed, but they must have a high adhesion to each other, since in the rim according to the invention a firm connection of the components with each other is necessary.
- a transparent polymer component for one injection molding unit may be made of a colored opaque polymer, and the outwardly facing half-shell made of a transparent polymer, which is necessary, for example, in molded-in LEDs.
- the half-shell facing the vehicle may be made of a colored opaque polymer
- the outwardly facing half-shell made of a transparent polymer, which is necessary, for example, in molded-in LEDs.
- a colored polymer for the inner half shell one could only partially cover the spokes with the polymer, since the inner half shell does not necessarily have to be geometrically congruent with the outer half shell. In this way can be different
- the metal composite consisting of the inner metal ring 1, the metallic spokes 2 and the outer metal ring 3 preferably consists of one piece, which was produced in a known manner by pressing or by a casting process.
- the metal composite can also be made of individual parts that have been welded together.
- LEDs or OLEDs are preferably used with suitable electrical connections and a wiring in the production of the half-shells in one of the half-shells or in the metal composite.
- the LEDs or OLEDs allow the targeted illumination of the rims.
- the visibility of the vehicle can be increased as well. Especially from the side of vehicles are often poorly lit and so difficult to see. A better illumination of the vehicle can thus significantly reduce the risk of accidents in poor visibility, especially when turning.
- the invention further includes the use as a vehicle wheel, preferably as a motor vehicle wheel for cars or trucks.
