专利说明:
The invention relates to a disc brake caliper, in particular for floating mounting, and to a two-piece brake caliper, a two-component disc brake with an electro-hydraulic parking brake, and an industrialization and assembly method. for automatic park brake with mechanical actuator with hydraulic assistance. This stirrup comprises first and second branches rigidly connected to each other by an arch to enclose the brake disc between them. According to the invention, the stirrup comprises: a first one-piece part, said attached barrel, forming the first branch and carrying the connection with the vehicle, and a second one-piece part, said attached vault, forming the stirrup arch and the second branch, which is rigidly connected to said first part by mechanical assembly means. The reported shaft is typically made of aluminum, and the vault is typically made of cast iron. The invention further relates to an industrialization process and a method of assembly, comprising the definition and assembly of several models of vaults reported on the same model of reported barrel, and vice versa. State of the art Disc brakes are a type of brake widely used in road vehicles, including four-wheeled and two-wheeled vehicles, particularly automobiles and light commercial vehicles. In a disc brake, a stirrup comprising two branches interconnected by a vault is integral in rotation with the vehicle, for example the knuckle forming the hub of the wheel. The stirrup spans a sector of a disc that is secured to the wheel, with a branch on each side of the disc. The stirrup encloses the disc between its branches via a pair of friction linings, or pads, one on each side of the disc. For braking, these pads are tightened against the disc by the action of one or more brake pistons, actuated in general by hydraulic pressure. This clamping thus creates a friction between the linings and the disk, which dissipates as heat the kinetic energy of the wheel and brakes. The service brake function is to slow the vehicle when it is moving, if necessary until it stops. In addition to the service brake, such a disk brake can also be implemented to also fulfill a function of emergency brake and / or parking brake, also called park brake. This function is usually obtained by another actuator, and usually on the rear wheels. Many vehicles are equipped with a more or less automated parking brake function, which is controlled by means of an electric control. FIGURE 1a to FIGURE 1d illustrates a type of disk brake including an electro-hydraulically actuated automatic parking brake function on a floating mount brake 1. In this type of assembly only one B1 of the arms of the caliper contains a brake piston 111 which bears on one 81 of the linings, and the other branch B2 directly receives the support of the other lining 82 called exterior. The support of the piston on one of the pads thus decreases the gap available between the two branches of the caliper, acting on one side of the disc 90. To compensate for this unilateral decrease, the caliper 11 as a whole moves in translation parallel to the Al direction of movement of the piston, for example by bores 71 axis A7 which slide on columns integral with the undercarriage. In service brake, the brake piston 111 is moved by a hydraulic pressure connected to the piston chamber by one or more hydraulic openings 18, for example for an inlet and a bleed screw. In parking brake, the displacement of the brake piston 11 is controlled by a mechanical device mounted inside a mechanical chamber 12, which is driven by an electric motor, in the housing closed by the cover 121. the clamping force necessary to ensure and maintain the immobilization of the vehicle over a long period, this mechanism is assisted by a second hydraulic piston mounted in a chamber 13, or "boost chamber". The latter receives, by means of hydraulic inlets 138, a hydraulic pressure controlled by an electrically controlled high-pressure hydraulic pump, for example of the order of 180 bar. Typically, as illustrated in FIGURE 1a, the mechanical chamber 12 is traversed by screws 137 which bear on the boost chamber 13. These screws are anchored in the stirrup 11 to clamp the two chambers against it and realize the assembly. These elements are generally made by molding. The mechanical chamber 12 and the boost chamber 13 are generally light alloy, typically based on aluminum. As illustrated in FIGURE 1b, the stirrup itself can also be made of a more rigid metal, typically cast iron, here represented in a clearer form. This allows a smaller footprint, as well as a lower absorption of effort that is to say a better "biting" braking. Optionally, as illustrated in FIGURE 1c, the mechanical chamber can also be integrated in the stirrup 11a, which is then made of aluminum alloy. Improvements and optimizations are constantly sought in the field, particularly in terms of weight, cost, performance, reliability, bulk, but also adaptation to dimensional constraints. An object of the invention is to overcome the disadvantages of the state of the art and to contribute to these improvements and optimizations, and to allow greater flexibility and ease of design and manufacture DESCRIPTION OF THE INVENTION The invention proposes a disc brake caliper for a vehicle, particularly a road vehicle, of the type comprising a first branch and a second branch connected to one another rigidly by an arch and arranged to enclose a sector of a disc between them. brake between pads under the action of at least one brake piston moving in a hydraulic chamber arranged at least in the first branch, which is provided to be mounted integral in rotation of the vehicle. According to the invention, this stirrup comprises: on the one hand a first one-piece part, called said casing, which carries out the first limb and carries one or more members intended to ensure the connection of said stirrup with the vehicle, and on the other hand a second one-piece part, said attached vault, which carries the stirrup arch and the second branch, and is rigidly connected to said first part by mechanical assembly means. The barrel reported typically comprises the hydraulic chamber, and carries the various members of fasteners, for example arms receiving columns in the case of a floating assembly. The vault thus includes the opposite part of the stirrup, also called the nose in the case of a floating assembly, which is supported on the outer lining. As can be understood, the vault can thus be manufactured according to a different process of the reported barrel, and / or in a different material. This independent vault thus allows a modularity in the architecture of the brake, in size or in material or both according to the needs, for example by providing several types of vault for the same stirrup base. Such modularity allows for example a greater flexibility to adapt to the constraints of different car manufacturers, for example for the size between stirrup rim. The result is greater flexibility, simplicity and economy in inventory design and management. By separately separating these two parts of the stirrup, in spite of the disadvantages generated by their assembly, the invention thus makes it possible to obtain different advantages for each part, optimized according to the needs of each part and of the assembly sought, and combine these benefits in one caliper. Preferably, the vault is made of a material different from that of the reported barrel, in particular of a better rigidity. The stirrup can thus enjoy the advantages of a material for the vault, while keeping the advantages of the other material for the barrel and its hydraulic mechanism. According to one feature, the casing is formed by a molded part made of an alloy mainly based on aluminum, and the added vault is formed by a part (preferably molded) of cast iron or an alloy predominantly based on iron. The reported shaft can thus benefit from the specific advantages of a lighter alloy, in particular the aluminum alloy: in particular the lightness, made possible by mechanical stresses less important than in the vault; and ease and precision of molding, resulting in less machining retouches and easier to achieve. The vault can thus take advantage of the specific advantages of a more rigid material, in particular cast iron: for example a lower cost and / or a smaller footprint for the same resistance. It also allows a better stiffness of the stirrup, therefore a reduced absorption, that is to say a better "mordant" braking obtained. Compared to a one-piece bracket, the separation between the reported shaft and the vault is provided in different positions, more or less close to the shaft. Preferably, this separation is provided at the birth of the vault, and the vault itself is entirely made by the second part. It is thus possible to realize a larger assembly surface, and to maximize the length of the vault that can be made of a different material. The invention is applicable to a single piston caliper, as described in more detail below. It is also applicable to a stirrup comprising in which the barrel includes at least two brake pistons arranged and actuated in parallel, for which the advantages are even more pronounced, because of the increased complexity of the shapes to be made in the caliper barrel . The invention applies in particular, but not necessarily, to a floating type assembly. In other types of mounting, for example with one or more pistons on the outside, the nose of the vault also includes a hydraulic chamber. In these other types of assembly, the composite appearance and the modularity that it provides confer the same types of advantages as for the floating assembly, at least for the parts located on the side of the caliper drum. According to another aspect of the invention, it is proposed a disc brake including at least one stirrup as described here, which is integral with a power park brake actuator is arranged to perform a brake function of park by acting on the brake piston of said caliper. According to this aspect, this actuator comprises: a mechanical chamber including a controlled electric drive mechanism, which is arranged to perform a clamping of said brake at least by pressing on said brake piston, and an assistance chamber including at least a second piston hydraulic device adapted to receive a hydraulic pressure of a hydraulic circuit under pressure so as to generate a support concurrent clamping achieved by the mechanism of said mechanical chamber. According to a first embodiment, the mechanical chamber and the boost chamber form two distinct subassemblies rigidly assembled on the shaft reported by mechanical assembly means. According to a second embodiment, the mechanical chamber and the shaft are formed as a one-piece element, on which the boost chamber is rigidly connected by mechanical assembly means. In the state of the art, the fact of integrating the mechanical chamber to the stirrup made it necessary to make it aluminum alloy. It was therefore impossible or even more difficult and expensive to make a cast iron caliper, for example because of the additional complexity of the forms provided by the mechanical chamber. By separating the stirrup in two parts, the invention thus makes it possible to obtain the advantages of cast iron for the vault, while at the same time achieving a single assembly incorporating stirrup yoke & mechanical chamber, since it can be made of aluminum alloy. This integration of the mechanical chamber, while taking advantage of the advantages of cast iron for the vault, makes it possible, for example: to no longer have to seal (air) between the stirrup drum and the mechanical chamber and / or a better alignment of their different mechanisms, and / or a decrease in the length and greater ease and flexibility of implantation of the anchoring screws of the boost chamber. Optionally, the invention also proposes to integrate the boost chamber stirrup barrel in addition to the mechanical chamber, with the same type of benefits. According to yet another aspect, the invention proposes: a stirrup element arranged to produce a second part, or attached vault, of a stirrup as described here, and / or a stirrup element arranged to make a first part, or be reported, of a stirrup as described here. According to another aspect, the invention provides a vehicle or subassembly of vehicle comprising at least one brake or stirrup as described herein. The invention also allows improvements in the industrialization process and manufacturing of such a brake or such a vehicle or subassembly of vehicle. Thus, according to another aspect of the invention, there is provided an industrialization process which comprises the following steps: providing an attached barrel of an existing type intended to produce a first type of brake or determined vehicle, typically by assembly with a first type of vault reported; and determining or selecting, according to a second type of brake or vehicle to be assembled, a second type of vault arranged to be assembled on said shaft and thus achieve said second type of brake or vehicle to assemble. Still according to another aspect of the invention, there is thus provided an assembly method which comprises the following steps: making or providing an insert barrel comprising positioning and fixing means for receiving indifferently several types of vault reported; choose a vault, in a choice of several types of vaults reported different sizes, depending on a type of brake or vehicle to assemble, for example according to size criteria or a brake version or vehicle to be produced; and assembling said vault attached to said barrel reported. Various embodiments of the invention are provided, integrating, according to all of their possible combinations, the various optional features set forth herein. List of Figures Other features and advantages of the invention will become apparent from the detailed description of a non-limiting embodiment, and the accompanying drawings in which: - FIGURE 1 illustrates a state of the art of a brake Floating-mounted disc equipped with an electro-hydraulically actuated automatic parking brake device, with: o in FIGURE 1a, an exploded part of such a brake in an all-aluminum version, with separate mechanical chamber and separate boost chamber on the caliper, o in FIGURE lb, a burst of such a brake in a version with cast iron caliper, o in FIGURE, an exploded of such a brake in a version with stirrup and chamber forming an aluminum one-piece element , and o in FIGURE 1a, a perspective view of such a brake once assembled; - FIGURE 2 is a top view on the scale of an exploded brake, in a first embodiment of the invention, with cast iron assembled vault on an aluminum caliper shaft, with chamber mechanical and boost chamber manufactured separately; FIG. 3 is a top view on the scale of an exploded portion of a brake, in a second embodiment of the invention, with an attached cast iron vault on an aluminum stirrup shaft, including one-piece mechanical chamber; FIGURE 4 is a scale view of the brake of FIGURE 2, in section along the axis of the brake piston; and FIGURE 5 is a perspective view at the brake scale of FIGURE 2, prior to assembly of the attached vault. Description of an exemplary embodiment As is understood, the invention makes it possible to associate a bi-material stirrup with an "APB-H" module, that is to say, enabling activation of parking braking by electro-hydraulic operation. The composite architecture within the caliper, implemented in a two-material cast-aluminum way, provides advantages in terms of mass and stiffness, which can be adjusted differently and more widely compared to the state of the technical. By associating this composite stirrup with a module of the APB-H type, the same advantages are obtained for the service braking while combining them with other advantages related to an optimization of the various chambers and stirrup parts. say the boost chamber, the mechanical chamber, the shaft reported and the vault reported. As illustrated in FIGURE 2 to FIGURE 5, this stirrup 20, 20b is composed of a cast iron vault 29 (shown in clear material) and a shaft 21, 21b made of aluminum alloy (shown in gray in the figures). . The two parts of the stirrup are made integral by two screws 27 whose heads are supported in housings 217 formed in the shaft 21, 21b and whose thread is held in the roof 29. First exemplary embodiment In the first exemplary embodiment of the invention, illustrated in FIGURE 2, FIGURE 4 and FIGURE 5, the APB-H module is composed of two independent aluminum alloy chambers, the mechanical chamber 22 and the booster chamber. 23. These two chambers are clamped together and against the shaft 21 reported by three screws 237, based on the boost chamber and whose threading is made in the shaft 21 of the stirrup 20. As illustrated in FIG. 4, the mechanical chamber 22 encloses in its interior space 210 a pinion 221, actuated by an electric motor enclosed by the cover 221. This pinion 221 is provided with an internal thread which drives in translation, in the axis brake piston 211, a screw 222 held in a flange 229. This screw 222 has a control end 224 which sealingly enters the hydraulic chamber 210 of the brake piston 211. It is linked in translation to a control end 212 of the brake piston 211. This mechanism thus forms an electromechanical actuator which provides the motion control to the tightening and loosening, by pushing and pulling the brake piston 211 by its control end 212. This electromechanical actuator is assisted in its clamping force (to the right of the figure), for the required clamping force, by a second hydraulic piston 231 housed in the internal space 230 a hydraulic chamber inside the chamber 23. This second piston 231 receives a high hydraulic pressure (about 180 bar) by a hydraulic circuit 238 assistance. This assistance pressure is provided, for example, by the ESP pump, or by an electrically actuated brake booster "i-booster" which also provides the main service braking assistance, under the effect of this pressure, this second hydraulic piston 231 presses on an assistance end 223 of the screw 222 of the mechanical chamber 22. Second exemplary embodiment In the second exemplary embodiment of the invention, illustrated in FIGURE 3, the stirrup shaft 21b integrates the mechanical chamber in a one-piece fashion of aluminum alloy. It thus allows additional advantages specific to the integration without sacrificing the advantages that a vault brings to another material, here cast iron. In this embodiment, compared with a brake with APB-H according to the state of the art with cast iron caliper as shown in FIGURE 1b, which can not integrate the mechanical chamber, the brake according to the invention retains the advantages of cast iron caliper while providing the following advantages: Total mass of the reduced brake, Optimization of the total length of the brake, since the caliper shaft and the mechanical chamber are fused in one piece 21b, Flexibility over the length and the positioning of the screws 237b fixing the boost chamber 23 on the part 21b thus fused, Elimination of an airtight zone E12 between the mechanical chamber and the stirrup shaft. Compared to a brake with APB-H according to the state of the art with aluminum stirrup, incorporating (FIGURE 1a) or not (FIGURE 1a) the mechanical chamber, this brake according to the invention allows the advantages of the cast iron caliper and thus brings the following advantages: Possibility of obtaining a higher stiffness of the brake and therefore a reduced absorption, Possibility to refocus the center of gravity of the brake towards the caps of small columns (ie towards the disk ). Compatibility with small dimensions requested by the manufacturer between the rim of the wheel and the vault of the caliper. Reduced thermal and electrical conductivity, and (due to separate parts ) Cost more economical than APB-H with all-aluminum bracket. Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention.
