Definitions

• the invention relates to a vehicle brake disc protector, particularly a motor vehicle. It also relates to a method of producing such a brake disk protector. Finally, it relates to a vehicle, in particular a motor vehicle, equipped with at least one such brake disk protector.
• disk protector To protect the brake tracks of the disk of a disc brake against splashing water, mud or other, it is known to fix on the axle of the vehicle a part called “disk protector". Conventionally, this disk protector is made of a pressed sheet metal sheet fixed at its central portion by a plurality of screws.
• brake disc protectors made in large series are, most often, completely steel. They are relatively heavy and have poor thermal insulation. To make them lighter, series of these protectors made of aluminum or aluminum alloy have also been made. These have the defect, when screwed or pinched on parts of different material, cast iron or steel for example, to generate a problem of galvanic corrosion. In addition, whether steel or aluminum, these disc protectors known from the prior art have the disadvantage of corroding.
• the object of the present invention is to provide a vehicle brake disc protector, particularly a motor vehicle, which is relatively light while providing the same functionality as all-metal protectors known from the prior art.
• Another object of the present invention is to provide such a brake disc protector, which has excellent mechanical and thermal properties, so as to meet the current specifications of the automotive manufacturing. Finally, it is also an object of the present invention to provide such a brake disc protector, which is of simple design and manufacture, which is robust, reliable and economical.
• the present invention relates to a vehicle brake disc protector, in particular a motor vehicle, which consists of two parts: a) a plastic envelope, which has a general shape substantially circular and which has on its periphery a cutout for providing space for a brake caliper, and b) a metal base, which is assembled to the central portion of the casing, holes being provided in the disc protector for the passage means for fixing the latter on an element of the vehicle structure.
• said base of the protector is made from a steel sheet and it is preferably assembled by bouterollage to the central portion of the protective casing.
• This base of the protector according to the invention can be achieved by stamping, or by machining by removal of material.
• the envelope of the protector is made by a plastic injection method of known type.
• circular orifices for example four in number, may be provided on the disk protector for the passage of screws for fixing the latter on an element of the vehicle structure.
• the present invention also relates to a method of producing a brake disk protector according to that described above in outline.
• This process new, comprises the following steps, taken in combination: a) production of the metal base by stamping a steel sheet, b) production of the plastic envelope by injection, and c) assembly of the metal base with the central part of the plastic casing by snap.
• FIG. 1 is an overall schematic perspective view of an exemplary embodiment of a vehicle brake disc protector according to the present invention
• FIG. 2 is a schematic perspective view of an exemplary embodiment of the so-called “envelope" part of a brake disc protector according to the present invention.
• FIG. 3 is a schematic perspective view of an embodiment of the so-called "base” portion of a brake disk protector according to the present invention.
• a brake disk protector according to the present invention, which consists of two parts, namely an envelope, general reference 10, and a base, reference general 20.
• the envelope 10 also shown only in the drawing of Figure 2, is made of a plastic material. It has a generally circular general shape and has a cutout 1 1 on its periphery. The cut 1 1 is intended to provide a space referenced A ( Figure 1) for the passage of a stirrup of a braking system (not shown).
• the base 20 also shown only in the drawing of Figure 3, is made from a steel sheet, which is assembled to the central portion 12 of the casing 10.
• the base 20 has also a circular opening 23, central, which is superimposed on the central opening 13 of the casing for positioning and fixing the brake disk protector on an element of the vehicle structure.
• the element of the vehicle structure, on which is fixed the brake disk protector may be a suspension arm or a pivot, for example.
• the envelope 10 of the protector made of plastic material, is preferably produced by a plastic injection process, and the base 20 is made by stamping or by machining by removal of material.
• the assembly of the base 20 on the central portion 12 of the casing 10 of the brake disk protector is preferably made by bouterollage, known method. in itself that allows to assemble different materials, such as metal and plastic, by heating and creep of the plastic material.
• Circular orifices referenced 20a in FIG. 3, four in number for example, may be provided for the passage of screws for fixing the disk protector on an element of the vehicle structure.
• the method of producing a brake disk protector according to the invention is as follows:
• the metal base 20 is made by stamping a sheet of steel, preferably, the plastic casing 10 is produced by an injection molding process, preferably, and
• the vehicle brake disc protector particularly a motor vehicle, as described above, has many advantages, among which the following advantages:
