[0074] Figure 1 The embodiment of a fluid distribution hydraulic circuit system is shown. The rotary drive device of the present invention can be applied to a rotary distributor and / or one or more gears in the system.

[0075] In this example the hydraulic circuit comprises 2 pumps P1 and P2, each distributing a fluid F1, F2, but a different number of pumps and fluids is within the scope of the present application.The fluid is distributed by a rotary distributor Di, for example of the type according to the invention and / or as described below.

[0076] Described below Figure 3A , 3B and 3C represent an example of a rotary distributor Di that can be used in the present invention. Figure 4 and Figures 5A-5D An example of a novel drive device according to the invention is shown, comprising a clutch and release mechanism for driving a rotary distributor, e.g. Figure 3A , 3B and the distributor shown in 3C, or used to drive other rotating parts.

[0077] Figure 1 The control system for fluid distribution in a hydraulic circuit shown comprises an electric motor 10, preferably a brushless electric motor (or "brushless" motor), which drives a central output shaft 14 which is simultaneously coupled to d gear sets (d ≥ 2).

[0078] exist Figure 1 In the embodiment, the shaft 14 is associated with different gear sets, but in reality these gear sets are arranged around the shaft 14 (e.g. Figure 2 An example of a gear set is shown). An electronic control unit 12, for example implemented in the form of a printed circuit board ("PCB"), controls this electric motor 10. The gears of the different gear sets are preferably spur gears with parallel axes.

[0079] In this example, each gear set includes a primary gear (E 1.1 -E 1.d ) in a gear.

[0080] These gears 1.1 …E 1.d Each of them drives, for example, an independently engageable / disengageable shaft A1 ... A1 in rotation, via an actuator, for example of electromagnetic (solenoid) or pneumatic or hydraulic type. Figure 1 In the electromagnetic actuator (or solenoid) S1, ...Sd is shown schematically, but other types of actuators are possible (hydraulic, pneumatic). Each separable shaft can be connected by a compression spring R1, ... R d Each actuator can be controlled by an electronic control unit 12 .

[0081] Described below Figure 4 The invention relates to a rotary distributor D i The clutch and release mechanism. This mechanism here comprises an electromagnetic type actuator, including a solenoid, but similarly, other types of actuators are also feasible (hydraulic, pneumatic).

[0082] exist Figure 1 In the embodiment shown, the system includes a second stage of d gears (E 2.1 -E 2.d ). Each gear of this second stage can be connected to a separable shaft and drives a rotary distributor D1, ...D d Therefore, the d rotary distributors are driven independently of each other.

[0083] It is worth noting that the actuator can be associated with any gear or shaft in each gear set; Figure 1 In the case of the gear, it is associated with the gear immediately before the distributor, but in Figure 4 In the case of the gears, it is associated with the gears associated with the distributor itself. Any gear in each gear set can be associated with a clutch and release device, which allows the corresponding distributor to be disengaged or engaged.

[0084] Each group of d distributors can be connected to a position sensor C1-C d The position signal is sent to the device 12.

[0085] Each rotary distributor D i There are ei Entrances (n ei ≥1) and n si Exports (n si ≥1), single entry (n ei =1) The distributor has multiple outlets (n si ≥2), single outlet (n si =1) The distributor has multiple inlets (n ei >1). The outlet is connected to a pipeline that delivers the fluid to a specific application, such as a cooling circuit or a circuit that requires oil or air supply (such as an air conditioning system) or hydrogen supply (such as a fuel cell supply system). Figure 1 In the example, distributor D1 has one inlet and two outlets, distributor D2 has two inlets and one outlet, and distributor Dd There are 2 inlets and 3 outlets; any other inlet / outlet combination can be implemented.

[0086] exist Figure 1 In the embodiment, the outlets of the distributors point to other components of the hydraulic system; however, as a modified example (not shown), one or more outlets of one or more distributors may point to one or more inlets of another one or more distributors.

[0087] An example of a rotary distributor that can be implemented in the present invention is described in patent application number FR-202101137; its structure is described in Figure 3A , 3B and 3C, see description below.

[0088] Furthermore, the fluid distribution system comprises p (p≥1) pumps connected to different distributors according to the specific architecture of the fluid distribution system under consideration.

[0089] Each group of d actuators S1,...S d The various dispensers can be controlled by means of the devices 12 as a function of their position; this position can be known by means of signals received by these devices 12 from corresponding position sensors.

[0090] In operation, the device 12 receives operating mode instructions 26 from the vehicle, each operating mode being defined by the engaged or disengaged state of each dispenser and the open and closed positions of all inlets and / or all outlets of the selected (or engaged) dispenser. When all dispensers have the same number x of possible positions, the total number of operating modes is equal to X. t The data associated with each operating mode may be stored in a storage device associated with the device 12, and the position of each dispenser may be determined by a sensor C. i Therefore, selecting an operating mode defines the engaged or disengaged state of each dispenser and / or the position of each engaged dispenser. The storage device may also store (or the device 12 may calculate):

[0091] - In what directions and / or angles each selected dispenser can be moved so as to change from a state defined by a certain combination of its inlets / outlets to a state defined by another combination of its inlets / outlets;

[0092] - and / or the order in which the selected dispensers should be engaged; all dispensers may be engaged simultaneously or sequentially (in a certain order), or some dispensers may be engaged simultaneously and the rest sequentially (also in a certain order).

[0093] When one or more dispensers need to be driven in the opposite direction to the previous driving direction, the rotation direction of the motor 10 is reversed. The dispensers that do not need to reverse the rotation direction can be separated. When one or more dispensers need to be driven in the opposite direction to one or more other dispensers, the latter can be separated.

[0094] Depending on the selected operating mode, the device 12 can activate the engagement or disengagement devices of selected dispensers and drive these dispensers by determining the rotational direction and angular displacement of each associated dispenser, and / or the activation sequence or order (sequentially or simultaneously as described above).

[0095] The motor 10 is then powered and the shafts are engaged (or not engaged) sequentially or simultaneously according to the determined sequence and / or position of each set of d distributors until each set of d distributors reaches the desired position.

[0096] Thus, the system can replace a product consisting of multiple valves driven by multiple brushless actuators with a group of hydraulic distributors driven by a single electric motor 10 (such as a brushless or stepper motor) and the engagement and disengagement mechanisms associated with each distributor.

[0097] The device 12, for example implemented in the form of a printed circuit board, may include a processor or microprocessor programmed to control the engagement / disengagement device and / or the electric motor 10 of each dispenser according to the various operating modes defined above, and / or to calculate the actuation of one or more dispensers according to the operating mode selected by the operator or the vehicle.

[0098] Figure 2 1 shows an embodiment of a single gear set combined with an electric motor 10. The figure shows the shaft 14 of the electric motor and the first stage E 1.1 Other identical or similar gear sets can be arranged around the motor. All these elements are fixed or mounted on a support 11. The support can be made of one or more independent parts mechanically connected by welding and / or mechanical systems, and / or composed of one or more materials, for example.

[0099] Figure 3A , 3B 3C represents one example of a rotary distributor that may be implemented in a system according to the present invention.

[0100] The rotary distributor has one inlet and two outlets, but it will be appreciated that it may have one or more inlets and one or more outlets.

[0101] The distributor comprises a cylindrical housing 200 or valve body which rotates substantially about the X axis, and a central part 400 , called the core, which is mounted in the housing 200 and can rotate in the housing 200 .

[0102] In the example shown, the housing 200 comprises an integral bottom 60 and a substantially cylindrical side wall 80, as well as a cover 100 for closing the housing. The cover 100 is fixed to the housing 200, for example, by welding (eg, ultrasonic welding).

[0103] The housing 200 is formed with a hole 180, referred to as a supply hole, in the side wall 80, and a supply conduit 220, for example welded to the bottom of the hole 180, for connection to a fluid source, for example Figure 1 On both sides of this inlet hole 180, the housing 200 also includes:

[0104] - a first outlet opening 210 formed in the side wall 80, extending into a duct 240 for conveying the liquid to a given area, for example an area requiring cooling;

[0105] - and a second outlet opening 120 extending into a conduit 140 for conveying the liquid to another given area.

[0106] The pipes 140 and 240 are welded, for example, to the bottoms of the holes 210 and 120, respectively. The housing 200 defines a hydraulic chamber 260. The outlet holes 120 and 210 are angularly distributed on the side wall around the X axis, on both sides of the supply hole 180.

[0107] The core 400 is used to be installed in the hydraulic chamber and can rotate around the X axis. It includes two end surfaces 280 and 300 and a side surface 320 .

[0108] The end face 280 faces the bottom of the housing and the end face 300 faces the cover. The end face 300 has a groove 310 for receiving the end of the actuator shaft, which is preferably aligned with the X axis. The cover 100 has an opening 330, opposite the groove 310, to allow connection with the shaft. As a variant, the end face 300 can have a protruding connection part for insertion into a groove formed on the actuator shaft. A seal 340 is preferably provided between the end face 300 and the cover around the groove 310 to prevent fluid leakage.

[0109] The core 400 further includes a first seal 440 for sealing the outlet hole 120 when aligned with the outlet hole 120, and a second seal 460 for sealing the outlet hole when aligned with the outlet hole 210. The first seal 440 and the second seal 460 have the same or similar shapes and are mounted on the core in the same manner.

[0110] Figure 4 The driving mechanism and actuator of a rotary distributor D are shown, and the distributor is, for example, a combination of the above Figure 3A , 3B, 3C, with an output shaft 29. The actuator here is of the electromagnetic type; it consists of a solenoid S which, when activated, drives a plunger 16, which has magnetic properties and can interact with the magnetic field generated when the solenoid is energized, thereby compressing a compression spring R. The plunger pushes the shaft 19 fixed to the gear 18, causing it to mesh with another gear 20, which is mounted on the shaft A and is driven by the motor 10, or by a drive device driven by the motor 10 (this gear itself is part of the gear set). The gear 18 extends in its central part into a compartment or cylindrical wall 27, which contains means (for example a key) allowing it to be coupled to the output shaft 29 of the distributor, while allowing the entire assembly containing the wall 27, the gear 18 and the shaft 19 to translate relative to the shaft 29. When the plunger pushes the shaft 19 towards the distributor D, the latter is meshed. When the action of the solenoid is weakened, the spring R pushes back the entire 18-19-27 assembly, causing it to disengage. The device may also include a brake 22 for braking the distributor (gear 18) when it is disengaged. The solenoid may be controlled by a device such as the above device 12. This rotary distributor D may be used in combination with the above Figure 1 and Figure 2 In the system described in , the rotary distributor here rotates in a plane perpendicular to its output axis.

[0111] Figure 5A , 5B , 5C, 5D represent a variant of the drive device, including a clutch and separation mechanism, such as for rotating the distributor D, such as the above combination Figure 3A , 3B , the type described by 3C; in these Figure 5A , 5B , 5C, 5D, the same reference numerals as in the previous figures, especially Figure 4 In the figure, the same components are represented.

[0112] The gear 18 is extended laterally into a skirt 118, preferably at the periphery of the gear, cooperating with a centering support 37 fixed to the support 11. For example, the centering support 37 guides the inner surface of a wall 118, while the outer surface of the wall carries the teeth of the gear.

[0113] The clutch device comprises a tooth coupling system 127 , 129 (or a tooth-and-groove coupling device), of which one part 127 is located, for example, at the end of the compartment or cylindrical wall 27 and the other part 129 is preferably located at the end of the distributor output shaft 29 . Figure 5DA more detailed representation of part 129 is shown, wherein the teeth 131-134 and the grooves 135-138 allow the teeth of part 127 to be received when the two parts are meshed, while the teeth 131-134 themselves are located in the corresponding grooves of part 127. The other part 127 thus has corresponding teeth and grooves. When these two parts are meshed, the output shaft 29 of the distributor can be driven by the gear 18. Figure 5D The number of teeth shown in FIG. 4 is 4, but a different number can be designed.

[0114] exist Figures 5A-5D In this variant, the translational guidance along the axis 19 is provided laterally by the means 37 and 118 at a position remote from the axis 19, while the coupling of the gear wheel 18 to the dispenser body 400 is provided in a central position.

[0115] The actuator S can thus drive the plunger 16 and thus the shaft 19 which is fixed to the gear 18 on the one hand and to the device 127 on the other hand. This makes it possible to:

[0116] - on the one hand, the gear 18 meshes with, for example, another gear 20, which is mounted on the shaft A (e.g. Figure 4 As shown), driven by the motor 10, or driven by a driving device driven by the motor 10 (this gear itself is part of the gear set);

[0117] On the other hand, the shaft 19 is brought into engagement with the shaft 29 of the distributor.

[0118] Thus, when the plunger pushes the shaft 19 toward the distributor D, the latter engages ( Figure 5A ), can be driven to direct fluid from one inlet to one outlet of the distributor. When the action of the solenoid S weakens, the compression spring R pushes the entire 18-19-27-127 assembly back, and the distributor D enters the separated state ( Figure 5B , the two parts 127 and 129 of the clutch device are separated). Figure 5C Another view showing the separation position.

[0119] like Figure 4 As shown:

[0120] - the rotary distributor (or more generally, the rotary element) can rotate in a plane perpendicular to its output axis;

[0121] - and / or the device may also include a brake for braking the distributor (and / or the gear 18) when it is disengaged;

[0122] - and / or the solenoid S can be controlled by a device such as the above-mentioned device 12;

[0123] - and / or rotary distributors can be used in conjunction with the above Figure 1-3C described in the system.

[0124] and Figure 4 compared to, Figure 5A , 5B The devices shown in 5C and 5D can reduce the wear of the gear teeth; these teeth can be made of plastic, such as PPA or PPS, and the above combined Figure 5A , 5B The clutch systems described in 5C and 5D may be made of metal, such as steel.

[0125] Figure 6 An exploded view showing shaft 19, gear 18 and clutch / disengagement elements with shaft 29; reference 130 and 139 indicate upper spring flange and lower spring flange, respectively. An upper gear coupling 127 and a lower gear coupling 129 can be seen, which are used to be fixed to the actuator shaft 19 and the rotating shaft 29, respectively.

[0126] Figure 4 and Figure 5A , 5B , 5C, 5D represent the driving mechanism of the rotary distributor D. However, one of these mechanisms can also be used to drive another rotating part, which has an axis 29, preferably perpendicular to the plane in which the rotating part can rotate; this other rotating part can be, for example, another gear, for example, combined with Figure 1 or Figure 2 Thus, one of these drive mechanisms can be used to drive a gear set, which itself drives, for example, another gear set or one or more distributors.

[0127] One application of the device or system according to the invention relates to the distribution of cooling water flows in vehicle cooling circuits. However, other applications may also be involved, such as the distribution of oil or gas (e.g. air or hydrogen) in vehicles (cars or trucks with internal combustion engines or electric motors or hybrids; or ships or aircraft), or the distribution of fluids in domestic applications, such as heat pumps.

[0128] In combination with the above and / or Figure 1 or Figure 2 In the fluid distribution hydraulic system or circuit described, each gear set may include at least two gear stages:

[0129] -First gear (E 1.1 -E 1.d ), wherein each gear is driven by the motor 10;

[0131] At least one of the primary and / or secondary gears and / or at least one (eg each) distributor is equipped with means S1-S for engaging or disengaging d .

[0133] - receiving the working mode instruction 26;

[0134] - Determine the target position of each group of d rotary distributors;

[0135] - Controlling the electric motor 10 and / or the means for engaging or disengaging each rotating distributor as a function of the target position of each rotating distributor.
