Definitions
- the present invention relates to a motor vehicle wheel rim.
- a very important parameter in determining brake efficiency is temperature.
- a principal aim of the present invention is to provide a vehicle wheel rim which solves the above-described drawbacks of conventional models, particularly by providing an efficient dissipation of the heat produced by the brakes.
- an object of the present invention is to provide a wheel rim which is structurally simple and can be produced, and even mass-produced, at competitive costs with respect to conventional wheel rims.
- Another object of the present invention is to provide a wheel rim the structure whereof allows executions having also a styling value.
- Another object of the present invention is to provide a wheel rim the mechanical and structural characteristics whereof are competitive with respect to conventional models.
- Another object of the present invention is to provide a wheel rim which can be produced in various types which are adapted for specific motor vehicles.
- Another object of the present invention is to provide a wheel rim which can be manufactured with conventional technologies.
- a wheel rim for vehicles characterized in that it comprises a front region which is shaped so as to form, upon assembly, at least one NACA air intake which is directed towards the corresponding brake and is adapted to extract the air adjacent to the corresponding brake from the inside outwards by suction induced by the centrifugal dynamics of the wheel rim.
- figure 1 is a perspective view of a wheel rim according to the present invention
- figure 2 is an elevation side view of the wheel rim of figure 1
- figure 3 is another elevation side view of the wheel rim of figure 1
- figure 4 is a partially sectional view of a detail of the wheel rim of figure 1
- figure 5 is a diametrical sectional view of the wheel rim of figure 1.
- a motor vehicle wheel rim according to the invention is generally designated by the reference numeral 10.
- the wheel rim 10 comprises a portion 11, which forms a corresponding annular channel lla wherein the tire, not shown, is fixed, and a front region 12 which is rigidly coupled to portion 11.
- the wheel rim 10 is made monolithically of aluminum alloy or of another light alloy.
- the front region 12 has an axial hole 13 adapted for the insertion of an end of one of the axles of the motor vehicle, not shown, and surrounded by through holes 14 adapted for the insertion of the bolts, also not shown, meant to fix the wheel rim 10 to the corresponding axle.
- the front region 12 is also shaped so as to form a seat 15 which is directed inwards, is coaxial to the hole 13, and is also meant to center and associate the wheel rim 10 with the corresponding axle.
- the front region 12 is shaped so as to form, when mounted on the axle, at least one NACA air intake 16 which is directed towards the corresponding brake, not shown, and is adapted to extract from the inside outwards, by means of a suction induced by the centrifugal dynamics of the wheel rim, the air which is adjacent to the corresponding brake and is overheated when the brake is being used.
- NACA intakes (the acronym stands for National Advisory Committee for Aeronautics) are conventionally "substantially triangular" air intakes designed for straight-line relative motions in order to provide the best possible compromise between maximum flow efficiency and minimum drag.
- air intakes 16 are disclosed and they are arranged radially and in a cross-like fashion.
- the intakes 16 have each a respective inlet end which has a narrower cross-section than the rest and is arranged towards the center of the wheel rim.
- the wheel rim 10 also has, in a circumferential region, a through hole 17 which is adapted for the insertion of the valve of the tire, which is not shown.
- the wheel rim according to the invention by removing by suction the heat produced by the brakes, achieves a very high dissipation efficiency, consequently maintaining an equally high efficiency of the braking system.
- wheel rim according to the invention can provide models having a high styling value.
- the embodiment and the wheel rim according to the invention do not entail particular technological problems and maintain production costs competitive with respect to conventional wheel rims.
- the present invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; thus, for example, the number of NACA intakes can be different from four arranged in a cross-like configuration; typically, a good aesthetic effect is produced by the provision of five or more radial NACA intakes arranged equidistantly.
