    DISC BRAKE CALIPER WITH PROTECTIVE PLATE INTEGRATING PLATES
    FIXING TO CALIPER DESCRIPTION
    TECHNICAL FIELD The invention relates to a disc brake caliper of a motor vehicle, such a stirrup carrying an actuator as well as pads or pads for pressing against the disc upon activation of the brake.
    STATE OF THE PRIOR ART
    Such caliper comprises a body of molded material including a base carrying an actuator and a first brake pad or lining, this base being extended by a vault ending in several fingers which carry a second plate or liner opposite to the first.
    When the actuator is activated, it presses the first plate against the brake disk. Since such a stirrup is typically mounted floating, that is to say mobile in translation perpendicular to the plane of the disc that it equips, the forces are balanced so that the two opposing plates are pressed in a balanced manner against the two faces of the disc. disk.
    For the braking to be effective, it is important that the caliper body has a high mechanical rigidity, so that it deforms as little as possible under the effect of the pressing forces exerted by the actuator. This is the reason why the body of such a stirrup is typically a molded piece to have a high mechanical rigidity, and in which are made different machining.
    In this context, the housing of the actuator which is formed in the base of the caliper body requires reaming the blank piece after molding, which involves passing a tool between the fingers to access the face of the base which is internal to the stirrup body, that is to say located in front of the fingers.
    In the case of a stirrup comprising a single actuator it comprises two fingers to define an access gap for reaming the single housing of the actuator in the base of the body. If the stirrup comprises two actuators, which are then located side by side in the base of the body, it comprises three fingers delimiting a first and a second spacing respectively allowing access to bore the housing of the first actuator and access to bore the housing of the second actuator in the base of the body. The object of the invention is to provide a solution for fixing a cover or protective plate hiding these fingers so as to obstruct the empty space between them, in particular to prevent the entry of dust in this region.
    SUMMARY OF THE INVENTION To this end, the invention relates to a disc brake caliper, comprising a body of molded material including a base extended by a vault and fingers extending the vault, a protective plate which is fixed and reported against the fingers to cover them, characterized in that the body comprises at least two holes, and in that the protective plate comprises at least two pads each engaging in a corresponding hole of the body to ensure the attachment of this plate to body, each stud having at least one radial lug forming retaining claw of the stud in the bore.
    With this arrangement, the protective plate has a limited manufacturing cost, and its assembly is limited to put it next to the fingers of the stirrup body with its studs vis-à-vis the holes formed in these fingers and then to press against these fingers to fully engage the studs in the holes. The invention also relates to a yoke thus defined, wherein the protective plate is a sheet metal plate having cylindrical studs resulting from cutting and stamping operations. The invention also relates to a yoke thus defined, wherein each radial lug has a tab-shaped delimited by a cutout formed in the wall of the cylindrical stud which carries it, this cutout having a shape corresponding to that of the letter U, each tab having a free end oriented towards an inner face of the plate and deployed radially to form a locking claw. The invention also relates to a yoke thus defined, wherein each stud has three pins regularly spaced around the axis of the stud which carries them. The invention also relates to a brake, comprising a stirrup thus defined and a brake disc.

    DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS The brake caliper according to the invention which is shown in Figure 1 where it is marked by 1 comprises a body 2 including a base 3 extended by a roof 4 which is itself extended by three fingers marked with 6, 7 and 8.
    As shown in Figure 1, the base 3 comprises two housings 9 and 11 for receiving two corresponding actuators not shown. Each housing is a borehole to receive for example a hydraulic piston. The bore of the first housing 9 is provided by engaging a corresponding tool between the fingers 6 and 7 along the axis A1, and the bore of the second housing 11 is provided by engaging a tool between the fingers 7 and 8 along the axis A2.
    As can be seen in FIG. 1, the first finger 6 comprises a blind hole 12 at its base, that is to say at the portion through which this finger is connected to the arch 4, this piercing being formed in the outer face of the finger, that is to say the face which is opposite the base 3. The last finger 8 also has a blind hole 13 at its base and on its outer face. Each piercing or blind bore 12, 13 is delimited by a cylindrical flank of relatively short length, and is closed by a preferably conical bottom face.
    These two holes 12 and 13 are intended to receive means for fixing a protective plate or cover 14 which is shown alone in FIG.
    This fixing plate or cover 14 which appears alone in FIG. 2 is formed from a flat metal sheet which is cut and stamped to form two cylindrical studs 16, 17 for attachment to the fingers of the stirrup body, these pads 16,17 engaging in the holes 12 and 13 of the stirrup.
    Each stud 16, 17 has a cylindrical base which projects from the inner face 18 of the plate 14 extending in a direction normal to it, as can be seen in FIG. 4, and which has an outside diameter slightly smaller than the diameter. internal holes 12 and 13.
    As can be seen in FIG. 5, the stud 16 has a cylindrical base or flange 19 of orientation AX normal to the internal face 18. This collar 19 is obtained by stamping a flat plate in which the protective plate is formed, so that it is delimited at one end by the body of the plate 14, and at its end by a circular edge 21
    This cylindrical base 19 has lugs 22 which protrude radially outwards. These lugs 22 which are regularly distributed around the axis ΑΧ of revolution, are arranged to block the stud 16 in the bore 12 by being anchored in the inner cylindrical face of this bore.
    As can be seen in FIGS. 5 and 6, each lug 22 is delimited by a cutout 23 having a shape corresponding to that of the letter U and which is made in the wall constituting the collar 19. This cutout is oriented to have the branches of the letter U adjacent the free edge 21 of the flange 19, and the base of the letter U joining these branches in the vicinity of the body of the plate 14. The lug 22 has a leg shape having its base close to the edge 21 and its free end in the vicinity of the face 18 and this tab is inclined outwardly, that is to say so that its free end is further from the axis AX than its base.
    Each lug 22 thus has its free end protruding from the cylindrical outer wall delimiting the body of the collar 19 so that its free end constitutes a claw. This claw retains or blocks the stud 16 when it is engaged in the bore 12, because it is then pressed against the cylindrical inner face of this bore 12.
    In the example of the figures, the cutout has the shape of the letter U to form the lug. A form of cutting according to the letter W makes it possible to constitute two claws to present a better grip. The number of pins that is two in the example of the figures is increased or decreased depending on the desired mechanical strength.
    In other words, when applying a force tending to move the plate 14 away from the fingers which carry it, the lugs 22 exert a reaction force which opposes this separation by preventing the stud 16 from coming out of the bore 12, the stud 16 is thus snapped into the bore 12.
    As will have been understood, the stud 17 is identical to the stud 16, it also has a flange having three lugs protruding laterally to form claws ensuring its retention and locking in the bore 13 in which it engages. In general, the mounting of the plate on the stirrup body that team is mainly to apply against the fingers by engaging the
    As indicated above, the plate 14 is made from a metal sheet which is cut and stamped with appropriate dies to delimit its periphery and the locking studs that it comprises, and which constitute its fixing means to the fingers stirrup body.
    In the example of the figures, the caliper body has two holes 12 and 13 formed at the base of the fingers 6 and 8, and the plate 14 has two corresponding fixing studs 16 and 17. The number of holes and studs can be increased to further improve the strength of the plate, depending in particular on the caliper body dimensions. For example, in the case of a stirrup whose base carries more than two actuators, the number of bores and studs can advantageously be increased.
    To reinforce the hooking of the lugs in the holes of the stirrup a groove is advantageously machined at the appropriate height in the latter so that the claws of the locking studs are deployed there.
