- the first water pump 6 could be an electric water pump and the second water pump could be a mechanical water pump.
- the two water pumps could both be electric water pumps.
- the invention can advantageously be used for the assembly of an electric water pump since such pumps are standard components requiring little or no adaptation to be integrated into a cooling system.
- the electric water pump 7 is illustrated in FIG. 2. It therefore comprises an electric motor 8, an electric connector 9 connected to the electric motor 8, a hydraulic inlet 12 and a hydraulic outlet 13.
- the hydraulic inlet 12 and the hydraulic outlet 13 each consist of a hydraulic connection capable of connecting the water pump 8 upstream and downstream to the circuit 5.

- the first water pump 6 and the second water pump 7 are fixed respectively to the engine block 3 and to a body element 1 1 of the vehicle.
- the water pumps are fixed to a frame or a fixed structure of the vehicle.
- the two water pumps 6, 7 could be indifferently attached to the engine block or to a body element or to two separate body elements.
- the term frame will be used to designate the element or structure on which the water pump 7 is fixed.
- the second water pump 7 is fixed to a frame by means of a dedicated support 20.
- the first water pump 6 can also be fixed to a frame by means of a support 20 '.
- the support 20 ′ may be a support according to the invention, or even a support identical to the support 20, or else it may be any support.

- the support 20 for fixing the second water pump 7, with reference to Figures 2 and 3.
- the second water pump will be more simply called "water pump”.
- the support 20 is presented in a state preceding the fixing of the water pump.
- the media is presented in a state as made available by a media manufacturer.
- the support 20 comprises a collar 21, a fixing flange 22 and a single clamping screw 23 of the collar 21.
- the collar 21 is a means of fixing the pump to the support 20.
- the fixing flange 22, or fixing lug is a means of fixing the support 20 to the frame.
- the support is made of metal.
- the support can be obtained by stamping a metal sheet.
- the support 20 includes sufficient rigidity to support the weight of the water pump under the operating conditions of the vehicle.
- the support is used to fix the water pump to the engine block 3, it will advantageously be designed to withstand vibrations of the order of 160Hz minimum.
- the support is used to fix the water pump to a body element 1 1, it will advantageously be designed to withstand vibrations of the order of 30Hz minimum.
- the thickness of the metal sheet used for the manufacture of the support can be chosen to achieve adequate robustness.
- the mounting flange 22 includes a geometry specific to the configuration of the vehicle in which the water pump is installed. It can comprise different more or less flat portions and inclined with respect to each other.
- the fixing flange further comprises two fixing holes 38, 39, one of which is oblong. These two holes 39, 39 allow the support to be fixed to the frame. These holes 38, 39 are intended to cooperate with fixing screws 40 (visible in Figure 4) engaged in the frame.
- the number of holes for fixing the support 20 can be any. As a variant, the support 20 could be fixed to the frame by other fixing techniques such as, for example, riveting, crimping or welding.
- the collar 21 includes a central opening of generally circular shape. It is formed by half-shells 24, 25 and a rotational articulation 26 between the two half-shells 24, 25.
- the two half-shells 24, 25 are therefore two separate elements from each other.
- the first half-shell 24 forms with the fixing flange 22 a one-piece assembly, that is to say an assembly formed by a single piece.
- the two half-shells 24, 25 are roughly in the form of a strip of substantially constant width extending along a semicircle. Both half shells can have a roughly identical shape.
- the shape of the half shells 24, 25 is defined to match the shape of a section of the water pump.
- the second half-shell 25 includes a boss 37 in the shape of a "U".
- the boss 37 When the water pump is in place in the support 20, the boss 37 covers the electrical connector 9 of the water pump.
- the boss 37 makes it possible to bypass the electrical connector 9.
- the boss 37 makes it possible to index, in particular by rotation, the pump on the collar 21 so that the latter can be easily assembled, in particular blind.
- the boss protects the electrical connector 9 against shocks, in particular projections coming from the running of the vehicle.
- the shape of the two half-shells could be quite different.
- the first half-shell 24 comprises two ends 27, 28.
- the first end 27 comprises a hook 29 and the second end 28 comprises a first opening 30 through which the clamping screw 23 passes.
- the second half-shell 25 comprises two ends 31, 32.
- the first end 31 comprises a hole 33 and the second end 32 comprises a second opening 34 through which the clamping screw 23 passes.
- the articulation in rotation 26 is obtained by the cooperation of the hook 29 with the hole 33.
- the second half-shell can therefore pivot relative to the first half-shell about an axis passing through the first end 27 of the first half -shell, coinciding with the first end 31 of the second half-shell.
- This axis is oriented generally perpendicular to the surface formed by the central opening of the collar 21. Consequently, the first two ends 27, 31 are always in contact with one another and the two second ends can move away from one another thanks to the articulation in rotation 26.
- the position of the hook and the hole could be reversed, that is to say that the hook could be arranged on the second half-shell and the hole be arranged on the first half-shell.
- One can in particular define an opening angle A1 as the angle formed between a first straight line passing through the two ends 27, 28, and a second straight line passing through the two ends 31, 32.
- the clamping screw 23 blocks the articulation in rotation 26 so that the two half-shells 24, 25 form a fixed opening angle A1.
- the angle A1 can be between 10 ° and 15 °, in particular it can be around 12 °. Consequently, the two ends 28 and 32, respectively of the first half-shell 24 and of the second half-shell 25 are not in contact with one another. These two ends are intended to come into contact with one another during the subsequent tightening of the clamping screw 23. Maintaining an opening angle A1 at a determined value can be obtained in different ways.
- the bringing together of the two ends 28 and 32 can be constrained by virtue of a specific configuration of the hook 29 and of the hole 33 which tends to separate the two ends 28 and 32 from one another.
- the hook 29 and the hole 33 can be designed so as to produce a restoring force tending to open the angle A1.
- said means used to produce a force for spacing the two ends 28 and 32 may be a spring not shown working in compression disposed around the clamping screw and interposed between the two ends 28 and 32 of the half cockles.
- the clamping screw 23 comprises on the one hand a screw head 35 bearing on the end 32, and on the other hand it comprises threads cooperating with a nut or a threaded opening arranged at the end 28.
- the end 28 may comprise a nut 36, for example welded to the end 28.
- the axis in which the clamping screw 23 extends is therefore defined by the orientation of the threads of the nut 36.
- the opening 34 comprises an oblong shape so as to allow the second half-shell to pivot relative to the first half-shell without the body of the screw interfering with the opening 34.
- the two half-shells deviate from one another under the effect of the 'return force until the screw head 35 abuts against the end 32.
- the position of the two holes 30, 34 and the screw could be reversed.
- the screw head could be supported on the end 28 while the nut 36 could be fixed on the end 32.
- the orientation of the clamping screw can be chosen so as to facilitate access to the head. screw for tightening this screw.
- maintaining an opening angle A1 at a determined value can be obtained by fitting threads in each of the openings 30 and 34.
- the threads of the two openings 30 and 34 would then both be engaged with the screw. Tightening.
- the pivoting of the second half-shell relative to the first half-shell when tightening the clamping screw could then induce a slight deformation of the half-shells.
- the restoring force tending to open the opening angle A1 could be obtained in any other way.
- it could be obtained by the simple effect of gravity acting on the second half-shell 25.
- the collar could consist of a single C-shaped element without any means of articulation.
- the two ends of the C would then have a design close or identical to the two ends 28, 32 described above. Maintaining an opening angle A1 at a predetermined value would be obtained by the form intrinsic to the necklace. During the subsequent tightening of the collar, its two ends could join thanks to an overall deformation of the collar.
- the support 20 may include a keying means to prevent an operator from mounting the water pump upside down.
- This keying means can for example be obtained by a portion of the collar which would come up against one of the hydraulic connections forming the hydraulic inlet 12 or the hydraulic outlet 13 of the water pump.
- the mounting of the water pump is obtained according to an assembly process which will now be described.
- a first step E1 the support 20 is provided as described above.
- the clamping screw 23 is engaged in the nut 36 so that the opening angle A1 is fixed at a value between 10 ° and 15 °, in particular so that the opening angle A1 is approximately equal to 12 °.
- the support is free, that is to say that it is not pre-assembled with the water pump.
- the central opening of the collar 21 is therefore free, in other words released.
- a second step E2 illustrated in FIG. 4 the support 20 is fixed to the frame (not shown) of the vehicle and / or of the powertrain.
- the fixing screws 40 are screwed through the two fixing holes 39, 39 of the fixing flange 22 in the frame.
- the mounting of the support 20 alone is easier than if it was preassembled with the water pump because it is lighter to handle and it is easier to access and / or the screws allowing it to be fixed to the frame are more easily seen.
- the clamping screw 23 is not manipulated and the opening angle A1 of the collar remains at the same value as during the first step E1.
- the support collar includes a clear central opening ready to receive the water pump.
- a third step E3 illustrated in FIG. 5, the water pump is brought in and it is inserted or, in other words, it is passed through the central opening of the collar 21.
- the opening angle A1 of between 10 ° and 15, preferably 12 °, makes it possible to obtain a central opening large enough to easily insert the water pump into the collar.
- a keying means prevents the water pump from being inserted in an orientation which would not be correct.
- the boss 37 offers a visual reference which makes it possible to orient the water pump correctly. The assembly operator can easily identify the electrical connector 9 on the water pump and rotate it so that its position coincides with that of the boss 37. Once in place, the electrical connector 9 is protected from impact by the boss 37 which covers it. The boss 37 also makes it possible to visually or mechanically ensure that the water pump is inserted at the correct depth in the collar 21.
- a fourth step E4 illustrated in FIGS. 6A and 6B, the clamping screw 23 is tightened to lock the water pump in position.
- the clamping screw 23 is screwed through the nut 36.
- the displacement of the screw head 35 bearing on the end 32 of the second half-shell 25 causes the second half-shell 25 to pivot according to the articulation in rotation 26.
- the end 32 of the second half-shell 25 approaches the end 28 of the first half-shell 24 until the two half-shells effectively clamp the body of the water pump.
- it is not necessary to bring the clamping screw 23 in a specific step because it is integral with the two half-shells.
- the clamping screw 23 is engaged in the nut 36 it does not move, and the operator can easily find the screw head 35 to screw it.
- the opening angle A1 between 10 ° and 15 °, preferably 12 °, allows a relatively small clamping stroke of the collar and therefore rapid clamping of the collar. This opening angle A1 is therefore the best compromise between ease of insertion of the water pump into the central opening and speed of tightening of the collar.
- the water pump is therefore fixed to the frame via the support 20. It is observed that the ends 28 and 32 of the two half-shells are in contact with one another. This prevents the two half-shells from over-tightening the water pump.
- the tightening torque of the tightening screw 23 can therefore be high enough to prevent any risk of loosening of this screw when using the vehicle, without risking damaging the water pump by excessive tightening.
- the water pump can be connected to circuit 5 via its hydraulic inlet 12 and its hydraulic outlet 13.
- the water pump can also be electrically connected to an electronic control unit via the electrical connector 9.
- the mounting process we can simply assemble the water pump to a vehicle frame.
- Water pumps do not need to be pre-assembled to a support which simplifies the management of water pump stocks which can be shared for different vehicles.
- the mounting process also does not require a mounting table on which the water pump is pre-assembled to the support.
- the work station for mounting the water pump is very simple since it requires only a stock of water pump on the one hand and a stock of supports according to the invention on the other hand.
