[0034] FIG. 1 shows an example of an embodiment of a rotary drive device according to the invention that can be applied in a system for distributing a fluid or in a hydraulic circuit, a rotary distributor and / or one or more gears of such a system.

[0035] In this example, the hydraulic circuit comprises two pumps P1 and P2, each distributing a fluid F1, F2, although a different number of pumps and fluids form part of the scope of this application. The fluids are, for example, distributed by a rotary distributor D of the type according to the invention. i and / or distributed as described below.

[0036] 3A, 3B and 3C show a rotary distributor D which will be described below and which can be used within the scope of the present invention. i Figures 4 and 5A to 5D, described below, show examples of novel drive means according to the invention, including a clutch and clutch release mechanism, for driving a rotary distributor, such as that of Figures 3A, 3B and 3C, or for driving another rotating member.

[0037] The system for controlling the distribution of fluid in a hydraulic circuit shown in FIG. 1 comprises a motor 10, preferably brushless, driving a central output shaft 14 which is simultaneously coupled to d gear trains, d≧2.

[0038] Figure 1 shows a shaft 14 associated with various gear trains, which in reality are arranged around the shaft 14 (for the gear trains as an example in figure 2). Electronic control means 12, manufactured for example in the form of a printed circuit board (PCB), control this motor 10. The gears of the various trains are preferably spur gears with parallel shafts.

[0039] Each gear train includes, in this example, a first gear in a first gear stage (E 1.1 , ...E 1.d ) is provided.

[0040] These gears 1.1 , ...E 1.d Each of the shafts A and B can be engaged / disengaged independently of the others, for example, using an electromagnetic (solenoid) or pneumatic or hydraulic actuator. 1 ...A 1 Figure 1 shows an electromagnetic actuator (or solenoid) S 1 , ...S d Although shown diagrammatically, other types of actuators (hydraulic, pneumatic) can be implemented. Each disengageable shaft is actuated by, for example, a compression spring (R 1 , ...R d ) may be held in an idle position. Each actuator may be controlled by electronic control means 12.

[0041] FIG. 4 is explained below and is for example a rotary distributor D i 1 shows a clutch and clutch release mechanism according to the invention for a i The actuators include electromagnetic actuators including, but again, other types of actuators can be implemented (hydraulic, pneumatic).

[0042] In the example embodiment shown in FIG. 1, the system has d gears (E 2.1 ...E 2.d Each of these gears of the second stage may be connected to a disengageable shaft, and a rotary distributor D 1 ...D d Therefore, these d rotary distributors are driven independently of each other.

[0043] It should be noted that the actuator may be associated with either the gear wheel or shaft of each gear train, in Figure 1 this is the wheel immediately preceding the distributor, whereas in Figure 4 this is the wheel associated with the distributor itself. Any gear wheel of each gear train may be associated with a clutch and clutch release means enabling the corresponding distributor to be disengaged or engaged.

[0044] Each of the d distributors preferably has a position sensor C that makes it possible to know at any time the position of the distributor to which it is associated. 1 ~C d The position signal is sent to the means 12.

[0045] Rotary distributor D i is n ei Entrances (n ei ≧1) and n si Exits (n si ≧1) and multiple exits (n si ≧2) ei =1) and multiple inlets (n ei >1) with a single outlet (n si =1). The outlet is connected to a duct that conveys the fluid to a given application, for example a cooling circuit or a circuit that must be supplied with oil or air (for example an air conditioning circuit) or hydrogen (for example a fuel cell supply circuit). In the example of FIG. 1, the distributor D 1 has one inlet and two outlets, distributor D 2 has two inlets and one outlet, distributor D d has two inlets and three outlets, but any other combination of inlets / outlets may be created.

[0046] In FIG. 1 , the outlets of the distributors are directed to other components of the hydraulic system, but alternatively (not shown), one or more outlets of one or more distributors may be directed to one or more inlets of one or more other distributors.

[0047] An example of a rotary distributor that can be implemented within the scope of the present invention is described in French patent application FR 202101137, the structure of which is recalled in Figures 3A, 3B and 3C, to which reference is made below.

[0048] The fluid distribution system further comprises p pumps (p>1) connected to the various distributors according to an architecture specific to the fluid distribution system considered.

[0049] d actuators S 1 , ...S d Each of these may be controlled by the means 12 depending on the position of the various distributors, which position may be known by signals received by these means 12 from corresponding position sensors.

[0050] During operation, the means 12 receives operating mode commands 26 from the vehicle, each operating mode being defined by the engaged or disengaged state of each distributor, as well as the open or closed position of all inlets and / or all outlets of the selected (or engaged) distributor. If all distributors have the same number of possible positions x, then the total number of modes is x t Data relating to each operating mode may be stored in memory means associated with the means 12, and the position of each distributor is equal to the position of the sensor C i The selection of the operating mode therefore defines the engaged or disengaged state of each distributor and / or the position of each engaged distributor. Optionally, the memory means further comprises: in what direction and / or with what angular displacement each selected distributor can be actuated in order to change it from one state defined by a particular combination of its inlets / outlets to another state defined by another combination of its inlets / outlets; and / or the order in which the selected distributors must be engaged, either all at the same time or sequentially (and this in a certain order), or even some of these distributors may be engaged at the same time and other parts sequentially (here again according to a certain order); may be stored (or even the means 12 may calculate them).

[0051] If one or more distributors must be driven in a direction opposite to the direction in which this or these distributors were previously driven, the direction of rotation of the motor 10 is reversed. Distributors whose direction of rotation is not reversed may be disengaged. If one or more distributors must be driven in a direction opposite to the direction in which one or more other distributors must be driven, it is possible to disengage the latter.

[0052] Depending on the selected operating mode, these means 12 may actuate the clutch or clutch release means of the selected distributor and actuate this or those distributors, for example by delimiting the direction and angular displacement of each of the distributors involved and / or the order or actuation sequence (sequential or simultaneous, as described above).

[0053] The motor 10 is then powered and, depending on the determined sequence and / or position of each of the d distributors, the shaft is engaged (or not) sequentially or simultaneously until each of the d distributors reaches the desired position.

[0054] This system therefore allows a production run of multiple valves controlled by a like number of brushless actuators to be replaced with a set of hydraulic distributors controlled by a single motor 10, e.g. brushless or stepper, and clutch and clutch release mechanisms associated with each distributor.

[0055] The means 12, manufactured for example in the form of a printed circuit board, may comprise a processor or microprocessor programmed for example to control the clutch / clutch means of each distributor and / or motor 10 according to a number of operating modes as defined above and / or to calculate the operation of one or more of the distributors depending on the operating mode selected by the operator or the vehicle.

[0056] FIG. 2 shows an example of an embodiment of a single gear train in combination with a motor 10. The motor shaft 14 and the first stage E 1.1can be seen in this figure. Other gear trains identical or similar to those shown in figure 2 may be arranged around the motor. All these elements are held or mounted on a support 11. This support may be made of one or more separate parts mechanically connected, for example by welding and / or a mechanical system, and / or may consist of one or more materials.

[0057] 3A, 3B and 3C show an example of a rotary distributor that may be implemented in a system according to the present invention.

[0058] This includes one inlet and two outlets, but it will be understood that it may include more than one inlet and more than one outlet.

[0059] The distributor comprises a valve body or housing 200 of essentially cylindrical shape rotating about an axis X, and a central part 400, designated as a core, mounted within the housing 200 and capable of rotating within the housing 200.

[0060] In the illustrated example, the housing 200 comprises a single-piece substantially cylindrical bottom 60 and side wall 80, and a cover 100 for closing the housing. The cover 100 is fixed to the housing 200, for example by welding, for example ultrasonic welding.

[0061] The housing 200 comprises an orifice 180, called the supply orifice, formed in the side wall 80, and a supply duct 220, for example welded to the base of the orifice 180, intended to connect to a fluid source, for example a pump, such as one of the pumps P1, P2 in FIG. 1. On either side of this inlet orifice 180, the housing 200 also comprises a first outlet orifice 210 formed in the side wall 80, extended by a duct 240 intended to convey the liquid to a given area, for example the area to be cooled, and a second outlet orifice 120 extended by a duct 140 intended to convey the liquid to another given area; Equipped with.

[0062] The ducts 140 and 240 are, for example, welded to the bases of the orifices 210 and 120, respectively. The housing 200 defines a hydraulic chamber 260. The outlet orifices 120 and 210 are angularly distributed over the side walls about the axis X on either side of the supply orifice 180.

[0063] The core 400 is intended to be mounted in a hydraulic chamber and can rotate about an axis X. It comprises two end faces 280, 300 and a lateral face 320.

[0064] The end face 280 faces the bottom of the housing, and the end face 300 faces the cover. The end face 300 comprises a hollow recess 310 intended to receive the end of a shaft of an actuator, preferably a shaft aligned along the axis X. The cover 100 comprises an opening 330 facing the recess 310, making it possible to couple the recess with the shaft. Alternatively, the end face 300 comprises a protruding coupling member intended to penetrate into a hollow recess formed in the shaft of the actuator. To prevent fluid leakage, a seal 340 is advantageously provided between the end face 300 and the cover in contact with the recess 310.

[0065] The core 400 also comprises a first seal 440 intended to seal the outlet orifice 120 when they face, and a second seal 460 intended to seal the outlet orifice 210 when they face. The first seal 440 and the second seal 460 are of the same or similar shape and have the same attachment to the core.

[0066] FIG. 4 shows a mechanism for driving a rotary distributor D, for example of the type mentioned above in relation to FIGS. 3A, 3B and 3C, equipped with an output shaft 29, and its actuator, here of electromagnetic type, the latter comprising a solenoid S which, when activated, activates a plunger 16, which has magnetic properties for interacting with the magnetic field generated when a current flows through the solenoid, compressing a compression spring R. The plunger thus presses a shaft 19 fixed to a gear wheel 18, which then engages another wheel 20 attached to the shaft A, itself actuated by the motor 10 or by a drive means (this wheel itself forms part of a gear train) driven by the motor 10. The wheel 18 is extended in its central part by a compartment or cylindrical wall 27, which comprises means (for example keys) that allow its coupling to the output shaft 29 of the distributor, while allowing the translation of the assembly comprising the wall 27, the wheel 18 and the shaft 19 relative to the shaft 29. The latter is engaged when the plunger presses the shaft 19 towards the distributor D. When the action of the solenoid is released, the spring R pushes back the assembly 18-19-27, which then changes to clutch release. The device may further comprise a brake 22 making it possible to brake the distributor (gear wheel 18) when it is disengaged. The solenoid may be controlled by means such as the means 12 described above. Such a rotary distributor D may be used in a system as described above in relation to figures 1 and 2, where the rotary distributor is rotated in a plane perpendicular to its output shaft.

[0067] Figures 5A, 5B, 5C and 5D show variants of the drive means including the clutch and clutch release mechanism of a rotary distributor D of the type described above in relation to Figures 3A, 3B and 3C, and in these Figures 5A, 5B, 5C and 5D, the same reference numbers as those in the preceding figures, in particular Figure 4, indicate the same elements.

[0068] The gear wheel 18 is extended on its sides by a skirt 118 preferably arranged on the outer periphery of the wheel and co-operating with a centering support 37 attached to the support 11. For example, the centering support 37 guides the inner surface of a wall 118 which bears on its outer surface the teeth of the wheel.

[0069] The clutch means comprises a dog system 127, 129 (or a tooth and groove coupling device), one part 127 of which is arranged, for example, at the end of the compartment or cylindrical wall 27, and the other part 129 of which is preferably arranged at the end of the output shaft 29 of the distributor. A more detailed view of part 129 is shown in FIG. 5D, whose teeth 131-134 and grooves 135-138 allow to receive the teeth of part 127 when these two parts are engaged, the teeth 131-134 themselves being inserted into the corresponding grooves of part 127. The other part 127 is thus provided with corresponding teeth and grooves. When these two parts are engaged, the output shaft 29 of the distributor can be driven by the wheel 18. The number of teeth shown in FIG. 5D is four, but a different number may be provided.

[0070] In this variant of Figures 5A to 5D, the translational movement along the shaft 19 is guided laterally by means 37 and 118 at a distance from the shaft 19, while the connection between the wheel 18 and the distributor body 400 is ensured centrally.

[0071] The actuator S can thus actuate the plunger 16, which translationally presses against the shaft 19, which is fixed on the one hand to the teeth 18 and on the other hand to the means 127. It is thus possible: - on the one hand, the meshing of the wheel 18 with, for example, another wheel 20, attached to the shaft A (as in FIG. 4 ) which is itself actuated, for example, by the motor 10 or by drive means driven by the motor 10 (this wheel itself forms part of a gear train); on the other hand, engaging the shaft 19 with the shaft 29 of the distributor.

[0072] As a result, when the plunger pushes the shaft 19 towards the distributor D, the distributor D is engaged (FIG. 5A) and can be actuated to guide fluid from the inlet to the outlet of the distributor. When the action of the solenoid S is released, the compression spring R pushes back the assembly 18-19-27-127 and the distributor D changes to clutch release (FIG. 5B, the two parts 127, 129 of the clutch means are disengaged). FIG. 5C shows another view of the disengaged position.

[0073] As shown in Figure 4, the rotating distributor (or, more generally, the rotating member) may be rotated in a plane perpendicular to its output shaft; and / or the device may further comprise a brake making it possible to brake the distributor (and / or the gear wheel 18) when the latter is disengaged; and / or the solenoid S may be controlled by means such as the means 12 described above, and / or The rotary distributor may be used in a system such as that described above in relation to Figures 1 to 3C.

[0074] Compared to Figure 4, the devices shown in Figures 5A, 5B, 5C and 5D can reduce wear, especially on the gear teeth, the latter of which may be made of a plastic, e.g. PPA or PPS, while the clutch system described above in relation to Figures 5A, 5B, 5C and 5D may be made of a metal, e.g. steel.

[0075] 6 shows an exploded view of the clutch / clutch release element with shaft 19, wheel 18 and shaft 29, where reference numbers 130 and 139 respectively denote upper and lower spring flanges, which show upper and lower dogs 127 and 129 intended to be attached to the actuator shaft 19 and rotary shaft 29 respectively.

[0076] Figures 4 and 5A, 5B, 5C, 5D show mechanisms for driving a rotary distributor D. However, one of these mechanisms may also be applied to drive another rotating member, preferably with a shaft 29 perpendicular to the plane in which the rotating member can rotate, this other rotating member being for example another gear wheel of a gear stage such as one of those described above in connection with Figures 1 or 2. One of these drive mechanisms may therefore also be used to drive a gear stage, which itself drives for example another gear stage or one or more distributors.

[0077] The application of the device or system according to the invention concerns the distribution of coolant flows in the cooling circuits of vehicles, but can also concern other applications, such as the distribution of oil or gas (e.g. air or hydrogen) in vehicles (cars or trucks with combustion or electric or hybrid engines, or boats or planes), or even the distribution of fluids in domestic applications, such as heat pumps.

[0078] In the systems or hydraulic circuits for distributing fluids described above and / or in relation to FIG. 1 or FIG. 2, each gear train comprises at least two gear stages: a first gear stage E whose gears are driven by said motor 10; 1.1 ~E 1.d , - a second gear stage E, each gear of which is driven by the first stage 2.1 ~E 2.d , and At least one gear of the first gear stage and / or the second gear stage and / or at least one, for example each, distributor is provided with a means S for engaging or disengaging it. 1 ~S d will be equipped.

[0079] In the system for distributing fluids or hydraulic circuits described above and / or in relation to at least one of the figures, comprising electronic means 12 for controlling a motor 10, these electronic means 12 are receiving an operating mode command 26; - determining a target position for each of the d rotary distributors; - controlling the means for engaging or disengaging the motor 10 and / or each rotary distributor depending on the target position of each rotary distributor; may be possible.

[0080] As described above and / or in relation to at least one of the figures, in the device or system or hydraulic circuit for distributing a fluid, the means for engaging or disengaging each rotary distributor or each rotary member may be, for example, of the electromagnetic type (S 1 , ...S d ) or a pneumatic or hydraulic actuator.
