    [0001] The present invention relates to a geared motor, in particular for motorizing a motor vehicle drum brake actuator, for example in the context of a motor-driven gear motor and a drum brake and a braking device thus equipped. drum brake type "dual mode". The present invention also relates to a drum brake and a braking device thus equipped.
    [0002] State of the art A geared motor is generally composed of an electric motor whose output shaft is connected to a gear assembly producing a reduction in speed and an increase in torque, which is very often advantageous for achieving a electric motorization. In most cases, a gearmotor includes pinions with external contacts that are cascaded. A conventional drum brake typically comprises a drum, coaxial with the wheel, and consisting of a hollow cylinder integral with the workpiece to be braked. During braking, the linings of the brake shoes rub against the inner surface of the drum. For this, an actuating means deviates from the axis one of the ends of each of the two segments. The opposite ends are supported, tangentially to the rotation, on an abutment plate integral with a rotatably immobilized plate. When the segments are pressurized against the drum track, any movement or force in rotation of the wheel prints a torque to the segments, they transmit to the plate by this stop plate. In general, the two segments are actuated at their two ends on the same side, typically by the same hydraulic cylinder with double piston, in a mode of operation called "simplex".
    [0003] It is also known to electrically actuate the segments of a drum brake. Thus, the document US Pat. No. 8,011,482 describes a mechanism in which the segments are actuated by a rod moved in translation by a screw-nut system which is actuated in rotation by a motor via a gear. EP 2 195 219 - 2 - discloses a parking brake system in which the segments are actuated by a threaded element displaced in translation by means of a wheel driven by an endless screw rotating in rotation with the shaft. output of an electric motor.
    [0004] An object of the present invention is to provide a geared motor well suited to a drum brake actuator, in particular compact, robust, economical and with a good energy efficiency.
    [0005] DESCRIPTION OF THE INVENTION According to a first aspect of the invention, the geared motor comprising an electric motor, a gearbox and a rotary output coupled to the electric motor via the gearbox, is characterized in that it further comprises a housing in which is fixed the motor and in that the gear is epicyclic gear and comprises at least one inner ring gear which is integral with the housing and formed in the material of said housing. An electric motor often provides high speeds of rotation, which requires to provide a very large gear to obtain a low displacement with sufficient effort. This is made possible by at least one fixed-ring epicyclic gearbox. In addition, when the environment of such a motorization is exposed to dust or dirt, the gearmotor mechanism must be protected and relatively sealed vis-à-vis the environment, particularly in the case of motorization of a motor actuator. drum brake. The geared motor mechanism according to the invention contained in a housing in which is formed the ring gear internally for the planetary gear train satisfies all or part of these constraints. The housing being immobilized in rotation, it provides the ring with the reaction torque necessary for the operation of the planetary gear train. It is also easy and economical to manufacture. The invention provides in particular a good energy efficiency of the transmission from the engine, which allows to obtain a greater effort or a higher speed of actuation or to use a less powerful engine, or a better compromise between these - 3 - performance. It allows ease and flexibility of adaptation to the needs and constraints of a vehicle designer or vehicle subassembly; for example for adaptation to existing vehicles or vehicle subassemblies, or for integration into vehicles or vehicle subassemblies being designed. In particular, the invention is compatible with the technical evolutions of the control modes of the automobile components, in particular in the case of the electrically controlled parking brake. It also makes it possible to implement several levels of engine performance with the same model of actuator. According to improvements of the invention: the gearbox comprises two epicycloidal gear trains mechanically mounted in series so that the output of a first of these trains is secured in angular position to the input of a second of these trains, said at least one crown comprising two crowns each forming part of one of the two trains; - The two rings are formed by a single toothing having an axial dimension corresponding to that of the two trains mounted in the housing following one another in the axial extension of the motor; the housing comprises a collar separating the motor and the gearbox, and the gearbox comprises a driving planet wheel, a planet carrier, and satellites which are mounted for free rotation on the journals of this planet carrier and in free translation. on these trunnions between the collar and this led planet carrier; in the case where there are two planetary gear trains, the second train comprises a driving planet wheel in rotation with a planet carrier of the first train, a planet carrier, and satellites which are mounted in free rotation on trolleys of this planet carrier led and freely translatable on these trunnions between the planet carrier and the planet carrier of the first train; the rotary output is integral with a driven planet carrier which is held axially by a snap ring engaged in a groove formed in the housing material at a first end of the ring gear, all the components movable gear unit having a mutual axial positioning freedom between the snap ring and a shoulder formed internally on the housing at a second end of the ring gear; - The crown and the motor are mounted coaxial.
    [0006] These improvements greatly facilitate the realization of such a geared motor, as well as its assembly and maintenance, which, therefore, reduces the costs incurred by such actions. The geared motor described here is adaptable to different types of drum brakes and braking functions. Drum brakes are typically used in motor vehicles to achieve three types of braking: - service braking, which consists in slowing down and / or immobilizing the vehicle, typically via a brake pedal; - Parking braking, which immobilizes the vehicle at a standstill, typically by means of a handbrake; - the emergency braking, which consists in slowing down and / or immobilizing the vehicle in the event of failure of the service braking, and which is typically provided by the same device as the parking brake.
    [0007] In most vehicles equipped with drum brakes, these three types of braking are performed by the same drum brake. Specifically and typically, the parking brake function is provided by a cable connecting a handbrake control in the passenger compartment to a lever pivoting in the drum about a movable end of a first braking segment and bypassing a second braking segment via a reaction rod. A drum brake thus actuated provides in simplex mode described above a braking torque which may be insufficient to provide parking braking and especially emergency braking.
    [0008] Thus, drum brakes operating in "duo-servo" mode have been developed, in which a floating link transmits and amplifies the effort from one segment to the other segment. In particular, an actuator moves one end of a first segment which rests on the drum while its other end bears, via the floating link, on the second segment by its end facing opposite, floating too. Thus, the opposite end of the second segment is the only one to bear on a stop plate. This type of brake greatly amplifies the actuating force but is more difficult to adjust and causes irregular wear of the linings. Duo-servo-type drum brakes are often used exclusively as a parking and emergency brake, for example, by using the central disk bell of a service disc brake as a drum, a combination called "drum-in-hat". and described in EP 0 416 760. Another type of brake combines the simplex mode for service braking and the duo-servo mode for parking and emergency braking. In this spirit, the document FR 2 697 599 proposes to add a mechanical actuator near the stop plate. This actuator is supported on one side on one end of a first segment and on the other on the end of an additional lever acting on the other segment. In its potential for adaptability to these different types of brakes and / or braking functions, a second aspect of the invention has other advantageous features according to which the invention may consist of a drum brake in which the two segments are mounted on a plate so as to be able to deviate from one another in order to bear on the friction track carried by the inside of a rotating drum relative to said plate, the actuator produced under the shape of a linear actuator being arranged to separate the two segments by their first two ends vis-à-vis one another. In such a brake, according to a feature, the two segments are articulated to a rod movable relative to the plate and which connects them in the vicinity of their second ends, opposite to the first ends, said link being able to transmit one of segments to the other of said segments a force which pushes the other segment in abutment against an anchor element fixed relative to the plate. According to another feature, the brake further comprises a second actuator providing a second braking function, in particular of service, this second actuator being arranged to separate from one another the second ends of the two segments while the first ends abut in relation to the plate. Finally, according to another advantageous characteristic, the invention consists of a braking device for a vehicle or a subset of a vehicle, in particular a road vehicle, comprising a brake disc interacting with brake pads to perform a second braking function, in particular service brake, this device comprising a brake arranged to provide a first braking function, in particular a parking brake and / or emergency brake, in which the drum is integral with, and coaxial with, said brake disk. 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 is an exploded view of the geared motor in an embodiment of the invention. invention; FIGURE 2 is a sectional view of the geared motor of FIGURE 1; FIG. 3 is a perspective and partial cutaway view of a parking brake or emergency brake actuator comprising the geared motor of FIG. 1, in one exemplary embodiment of the invention; FIGURE 4 is an exploded view of the actuator of FIGURE 3 without the geared motor; FIGURE 5 is an exploded view of the actuator of FIGURE 3; FIGURE 6 is an exploded view of the actuator of FIGURE 3 and a drum brake plate, in one embodiment of the invention; FIG. 7 schematically represents, in front view, the operation of a "dual-mode" type drum brake mechanism during the clamping, stationary vehicle, of the parking brake; FIGURE 8 is a perspective view of a dual-mode drum brake mechanism including the actuator of FIGURE 3, in one embodiment of the invention. Description of an Exemplary Embodiment In the embodiment of FIGURE 1, the geared motor 5 comprises an electric motor 52, for example a DC motor of generally cylindrical shape. This motor is enclosed in a casing 51 of generally cylindrical shape, on which is assembled in a sealed manner a rear cover 54, which is sealed through the electrical son 529 supply and / or motor control.
    [0009] Advantageously, the housing 51 is provided with a cylindrical inner housing with a diameter large enough to accommodate motors of several different diameters, for example up to 34 mm, so as to be able to manufacture geared motors 5 of several different power values with the same model of case.
    [0010] To properly position and maintain the motor in the housing, regardless of the diameter of the motor, it is fitted into a tubular shim 53 whose thickness is the difference between the radius of the motor 52 and that of the inner housing of the housing 51 For a given range of motors of different diameters, it suffices to manufacture a range of shims with the corresponding inner diameters, which is simpler and more economical than to manufacture packages of different sizes. Alternatively, the tubular shim 53 is integral with the rear cover 54, or even formed thereon. Alternatively, this cover has a more elongated shape than that shown, so as to cover the entire length of the motor 52. In this case, the range of different motors advantageously corresponds to a different range of covers, for the same housing 51. The tubular wedge 53, or the cover 54 if it replaces it, is furthermore made of a material which forms a screen against electromagnetic disturbances and / or which produces a thermal diffuser for the heat produced by the motor. On the motor shaft side, the housing 51 has a cylindrical outlet opening 510 enclosing a gear reducer, which is driven into the motor 52 and outputs the output shaft 557 of the geared motor. As shown in FIGURE 2, the motor 52 and the gearbox 55 are separated by a collar 57 which is integral with the housing and protrudes radially inwardly from the inner surface of the housing.
    [0011] The housing of the motor 52 comprises at least one eccentric tooth 528 which fits axially in a recess 543 of the cover 54 to immobilize the motor 52 against any rotation in the housing 51. The motor shaft passes through the collar 57 and a sealing flange 561 backed to the collar. It carries a pinion 551 which is integral with it and forms a sun gear leading to a first epicyclic gear 55A in which first satellites 552 meshing with this sun gear and with a first ring gear 559 internally that surrounds them. The first satellites 552 are mounted for free rotation on eccentric journals of a first planet carrier 553, and in axial translation on the journals between the collar 57 and the first planet carrier 553. This constitutes the exit of the first train epicyclic 55A and carries a sun gear 554 which it is integral in rotation, forming the input of a second epicyclic gear 55B comprising second satellites 555 meshing with the sun gear 554 and with a second ring gear internally surrounding them. The second satellites 555 are mounted for free rotation on pins of a second planet carrier 556, and in axial free translation on these journals between the first planet carrier 553 and the second planet carrier 556. This latter constitutes the exit of the second epicyclic gear 55B and carries the output shaft 557 of the geared motor 5, which it is secured.
    [0012] The second planet carrier 556 is held in axial position in the opening 510 with a suitable operating clearance by a snap ring 563, for example a circlip (registered trademark), engaged in a groove formed internally in the housing material. 51. In this embodiment, the two trains 55A, 55B are mounted in the housing 51 following one another, in the axial extension of the motor 52. The set of moving components of the gearbox 55 has a mutual axial positioning freedom for a suitable operating clearance between the snap ring 563 and a shoulder 58 formed internally on the housing 51, in particular on the collar 57. - 9 - The first and second rings are coaxial with the motor 52. Preferably, the two trains are corrected helical teeth. The two internally toothed rings are formed in the material of the housing 51, on the inner face of the opening 510. Preferably, the housing is made of moldable material and the two rings are integrally molded with the housing. It is also preferred that the two rings have the same diameter and the same size of teeth (except possibly the axial length of the toothing, the second train undergoing efforts that are multiplied by the reduction ratio of the first train). Very preferably, as shown in FIG. 2, the two rings are made by one and the same toothing whose axial dimension is sufficient for it to be simultaneously part of the two planetary gear trains. The housing 51 and the cover 54 of the geared motor are made for example of molded metal, or glass fiber-filled polymers. The satellites 552, 555 are made for example of polyoxymethylene. The planet carriers 553, 556 and their output shafts 554, 557 with the output drive shape are made for example of steel, machined or laser sintered.
    [0013] In an exemplary embodiment, the teeth and dimensions of the geared motor 5 were determined to produce a reduction ratio of a value of 23.04: 1 for a yield between 0.85 and 0.92. In the embodiment of FIGS. 3 to 8, the rotation of the gearmotor 5 is transmitted to a linear actuating assembly 3 of a parking or emergency brake, by a transmission gear 4 comprising parallel-axis gear wheels, interconnected and mounted to transmit the rotary motion of the actuator to one of the elements of the linear actuator assembly. The axes of these gears are also parallel to the axis of rotation of the gearmotor 5 and the direction D2 of the linear motion obtained. The linear actuating assembly 3 is mounted in a housing 21, also called main housing. The housing 21 serves to anchor the linear actuator 2 on a platen 10 of a drum brake as shown in FIG. 6. The housing 21 is made of, for example, metal such as cast aluminum. On this main housing which is inside the drum is assembled a secondary housing 23, so as to enclose between them sealingly (at least dust) the transmission gear 4 comprising a plurality of external contact gear wheels, here three gear wheels with helical teeth corrected. In this embodiment, the input wheel 41 of the transmission gear 4 is coupled in rotation with the gearmotor 5, here by interlocking an axial bore carrying a drive shape (not shown) with a geared form. complementary drive (not shown) carried by the output shaft 557 of the geared motor 5. The geometry of these two complementary drive forms is advantageously chosen of a type which allows between them a certain angular clearance with little or no damage and loss of efficiency of the transmitted power. This geometry is here of the multi-lobular type, for example six-branched or hexalobular as defined by the ISO 10664 standard, or in a five-branch version, or any of the versions proposed under the name " Torx "(registered trademark) by Textron.
    [0014] As shown in FIGURE 4, the secondary housing 23 is provided with a housing 25 which receives the output shaft 557 of the gearmotor 5, and in which the housing 51 engages sealingly by its portion surrounding the gearbox. Once the transmission gear 4 in place in the housing 24 of the secondary housing, its input wheel 41 is in place in the housing 25 to automatically mate with the output shaft 557 of the geared motor when its housing 51 is fitted with axial movement in the housing 25. Screws 233 are then inserted to fix the housing 51 of the gearmotor to the secondary housing 23, in a manner preventing the housing 51 from rotating about its axis despite the reaction torque experienced by the crown 559. As shown in FIG. 6, the linear actuator 2 is mounted and fixed on the inside face of the plate 10 while being engaged in a substantially leakproof manner in an opening 100 of the plate 10 so that the secondary casing 23 extends beyond the outside the drum. Then, the geared motor - 11 - is assembled as exposed above to the secondary housing which protrudes from the plate on the opposite side to the segments, that is to say on the "back" side of the plate. Thus, the geared motor 5 and the linear actuating assembly 3 have substantially parallel axes and are arranged on two opposite sides 5 to one another with respect to the plate 10. As can be seen in FIG. 6, the geared motor 5 and the secondary housing 23 are the only part of the linear actuator 2 to be protruded from the rear of the plate 10. The additional space requirement related to the electrical actuation is thus limited, and can be housed in a small cutout in the fixing bracket of the plate 10, for example on an oscillating arm of a half-rear axle. FIGURE 8 illustrates a "dual mode" drum brake mechanism in one embodiment of the invention. This embodiment can be implemented with different types of actuators for the service brake mode. Linear actuator 2 (see also FIGURE 7) provides actuation in parking brake or emergency mode. The linear actuating assembly 3 presses first ends 122, 132 of the segments 12, 13 to move them away from each other, and thus put the segments in abutment against the friction track of the drum 15 of the brake. From the rest position, or from the service braking position, the linear actuator 2 thus puts the brake in the parking braking position, and the return to the rest position is achieved for example by return springs connecting between they both segments by soliciting them towards each other. When the brake is in the parking braking or emergency position, the assembly formed by the two segments interconnected by a connecting rod 14 in the vicinity of their second ends and by the linear actuating assembly 3 in the vicinity of their first ends 122, 132 tends to be rotated with the drum. This movement is prevented by abutment of one of two shoulders 329, 339 (depending on the direction of rotation) of the linear actuating assembly 3 against a corresponding surface of the housing 21. The embodiment just described is in no way limiting. In particular, the elements specific to the actuator 2 of the parking brake or emergency brake can be integrated as such within any type of drum brake, including a two-mode drum brake type duo- servo or drum-in-hat type.
