detailed description

The direction in which a vehicle, in particular a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called transverse direction Y The third direction, perpendicular to the other two, is called vertical direction Z. Thus, we use a direct reference XYZ in which transverse direction directed to the right and Z is the vertical direction directed upwards. The forward direction is the direction in which the vehicle usually travels in the longitudinal direction and is opposite to the reverse direction.

There schematically illustrates a vehicle 1, preferably a motor vehicle. The vehicle 1 is preferably a vehicle propelled and/or towed by electric energy. Preferably, the vehicle 1 comprises at least one battery and at least one electric motor (not illustrated). The vehicle 1 also includes a body or chassis 2. As illustrated in the , the vehicle 1 or the body 2 preferably comprises a right front spar 3. The vehicle 1, or the body 2, also includes a crosspiece 4 for reinforcing an apron. Thus, the crosspiece 4 is a reinforcement of an apron, the apron extending between a front engine compartment and a passenger compartment of such a vehicle. As illustrated in Figures 1 and 3 in particular, the vehicle 1, or the body 2, also includes a support 10 which will be described in more detail below. The support 10 comprises a main part 20 and a secondary part 30.

As illustrated on the , 3, 4 and 6, the vehicle 1 or the body 2 also includes a water pump 5. For example, the power of the water pump is of the order of 150 watts. Such a pump is used for example to circulate a liquid to cool and/or heat the traction and/or propulsion battery(ies) of the vehicle 1. Preferably, the water pump 5 comprises a damping or filtration means 6 vibrations, as illustrated in Figures 2, 3, 4 and 6. For example, this vibration damping means surrounds the pump 5. For example, the means 6 is made of rubber or elastomer. The means 6 comprises an orifice for the passage of the secondary part 30 of the support 10.

Preferably, as illustrated in the , the secondary part 30 of the support 10 is intended to receive the pump 5, more precisely to receive the damping means 6 surrounding the pump 5. The secondary part 30 comprises an extension 36. The extension 36 is preferably intended to extend vertically or substantially vertically, once installed at the level of the body 2. For example, the extension 36 comprises a slot 37 dividing the extension 36 into two fingers 38. The damping means 6, preferably elastic or in elastic part, comprises one or two orifices intended for the passage of the extension 36 of the secondary part. As will be explained later, due to the elasticity of the means 6 and the size of the orifice(s) provided in this means 6, a press is necessary to fit the extension 36 of the secondary part into the means 6. Once this fitting has been carried out, an assembly 35 is obtained comprising the pump 5, the first damping means 6 and the secondary part 30 illustrated in particular on the .

There illustrates the main part 20 of the support 10 mounted on the body. The main part 20 is intended to be fixed on the spar 3. Alternatively or in addition, the main part 20 is intended to be fixed on the crosspiece 4 reinforcing the deck. Preferably, the main part 20 of the support 10 comprises two holes 23 (see ) intended to allow the passage of two screws 11 to ensure the fixing of the main part 20 on the crosspiece 4 and/or on the spar 3. For example, the screws 11 have an M8 type thread. For example, added nuts are provided within the spar or behind the spar, and/or added nuts are provided within the crossmember or behind the crossmember to allow cooperation with the threads of the screws 11. More screws, or a single screw supplemented by a holding means and/or an anti-pivoting means of the support around the single screw is also possible to ensure the fixing of the support to the body.

As mentioned previously and illustrated in particular in Figures 4 and 8, the support 10 comprises the secondary part 30. The secondary part 30 is intended to hold, support and fix the water pump 5 on the support 10. For example, the part secondary is folded so as to comprise a right angle or substantially a right angle between the extension 36 and a base 32. The support 10 also comprises a fixing means 40 which can be dismantled, unscrewed, separable, dissociable, or unclipable. In any case, the fixing means 40 makes it possible to ensure removable fixing of the secondary part 30 on the main part 20. Preferably, the secondary part is fixed on the main part via a vertical, or substantially vertical, translation , from top to bottom.

In the embodiment illustrated in Figures 4, 5, 6, 7, 8 and 9, the fixing means 40 preferably comprises two threaded rods 21. For example, each threaded rod extends from the main part 20, by for example by being fixed, for example welded, at the level of a base 22 (see Figures 5 and 9). For example, each threaded rod has an M6 type thread. Preferably, the base or plate 22 extends in a longitudinal and transverse plane, or substantially longitudinal and transverse, once the main part 20 fixed on the body, as illustrated in the . The fixing means 40 further comprises two holes 31 provided in the secondary part 30. For example, as illustrated in the , one of the two holes is an oblong hole 33. Alternatively, the two holes are oblong, for example by having axes perpendicular to each other so as to offer a wide range of possible positioning of the secondary part on the main part and/or or to allow wide tolerances at the locations of the threaded rods 21 on the base 22. In fact, the two holes 31, 33 are crossed by the two threaded rods 21 for fixing the secondary part to the main part. As a reminder, the assembly is ensured by a vertical translation towards the bottom of the secondary part (more precisely of the assembly 35 seen previously) so as to make the threaded rods 21 of the main part and the holes 31, 33 of the secondary part. Finally, the fixing means 40 comprises two nuts 41 cooperating with the two threaded rods 21 allowing the secondary part to be held in position on the main part by their tightening.

According to a variant of the embodiment, illustrated on the , the fixing means 40' comprises a second damping means 45. The second damping means 45 is placed, arranged, interposed between the main part 20' and the secondary part 30' of the support. The means 45 is for example made of rubber and/or elastomer, for example of the anti-vibration pad type. Preferably, the fixing means 40' then comprises a screw 25'. For example, the single 25' screw has an M8 type thread. The fixing means 40' also comprises a hole 21' made in the base 22' of the main part 20' and a hole 31' made in the secondary part. The holes 21', 31' are then crossed by the screw 25' to ensure the fixing of the secondary part relative to the main part. The fixing means 40' also comprises a nut 41' capable of cooperating with the screw 25'. Advantageously, the damping means 45 is inserted, stuck in the hole 21' and protrudes above and below it. Thus, the secondary part assembled via a translation from top to bottom towards the main part does not have direct contact with the main part. Indeed, part of the means 45 is found between the secondary part and the main part and another part of the means 45 is found between the nut 41' and the main part. The nut 41' or a washer arranged above then comes into contact with the damping means 45. Preferably, the head of the screw 25' comes into contact with the secondary part 30' around the hole 31'. Thus, the secondary part 30' sandwiches with the nut 41' or a washer at this level, the vibration damping means 45 and the base 22' at the level of the hole 21'.

Advantageously, in the variant of the embodiment, the main part 20' comprises a first blocking means 52. The secondary part 30' then comprises a second blocking means 53 to cooperate with the first blocking means 52. Thus, the means blocking 52, 53 prevent any pivoting of the secondary part 30' relative to the main part 20', in particular around the axis A' of the screw 25'. For example, as shown in , the first locking means 52 is a flat or rectilinear or substantially rectilinear edge or edge of the base 22' in which the hole 21' is formed. In this case, the second locking means 53 is a lug or fold extending towards the base, that is to say downwards if the secondary part 30' is fixed above the base . Alternatively, the first locking means can be a lug or fold extending projecting from the base towards the secondary part while the second locking means is a rectilinear or substantially rectilinear flat or edge of the secondary part. Alternatively, the main part may comprise an orifice and the secondary part may comprise an extension which is inserted into such an orifice, preferably with play, when fixing the secondary part to the main part. Alternatively, the secondary part may comprise an orifice and the main part may comprise an extension which is inserted into such an orifice, preferably with play, when fixing the secondary part to the main part. Obviously, other anti-pivoting means of the secondary part relative to the main part may be suitable.

In any case, preferably, a fairly substantial clearance is provided between the main part and the secondary part at the level of the first and second blocking means.

Both in the embodiment and in the variant, preferably, as illustrated in particular in the , the main part of the support comprises a first receiving means 80. The first receiving means comprises for example a tab extending upwards or substantially upwards, substantially in a vertical and transverse plane. For example, the tab comprises at least one fold 83, 83', for example two folds so as to offset the zone holding a hook 82 above the crosspiece 4 as illustrated in particular in the . In addition, in particular for purposes of rigidity, the tab comprises for example at least one rib or stamping 84, 84' at the level of each fold 83, 83', as illustrated in Figures 9 and 10. The first receiving means 80 is intended to maintain or participate in maintaining for example a pipe 8 of a braking circuit of the vehicle as illustrated in Figures 2, 3, 9 and 10. For example, as illustrated in Figures 4, 5 and 8, the first receiving means 80 comprises a threaded rod 81, for example extending longitudinally towards the front. For example, the threaded rod 81 allows the attachment of the clip or hook 82 intended to receive, in particular to lightly pinch, the pipe 8. Note that preferably, at this level of the braking circuit, the pipe or conduit is rigid, c i.e. it is preferably a metal pipe. Alternatively, a hole is provided within the first receiving means 80 so as to allow the insertion of a projecting part of a clip or hook to ensure the fixing of the clip relative to the support.

Both in the embodiment and in the variant, preferably, as illustrated in particular in the , the main part of the support comprises a second receiving means 70. The second receiving means 70 comprises for example a tab extending in a vertical and longitudinal plane, or substantially vertical and longitudinal, for example towards the front. For example, a base 72 of the tab comprises at least one fold 73. For example, the second receiving means 70 comprises at least one hole. Alternatively, the second receiving means 70 comprises at least one tapping 71. Alternatively, the second receiving means comprises at least one added nut. Preferably, two added nuts are fixed on the tab 70, for example by being welded to the tab or crimped on the tab. Preferably, the second receiving means 70 is intended to maintain or participate in maintaining for example an air conditioning solenoid valve or evaporator solenoid valve 7, in particular with a voltage of 12 V, as illustrated in particular in Figures 9 and 10. For this, by example, two screws 75 cooperate with the threads of the tab 70 by passing through a plate 74 supporting the solenoid valve 7. Preferably, anti-vibration means or anti-vibration or damping pads 76 or vibration filtration, are arranged between the fixed plate to the solenoid valve and the support at the level of the tab 70. For example, such means 76 are made of rubber and/or elastomer. The means 76 make it possible to avoid the transmission of vibrations from the support to the solenoid valve, in particular from the pump 5 to the solenoid valve, and/or from the solenoid valve 7 to the main part of the support if necessary.

Both in the embodiment and in the variant, preferably, as illustrated in particular in the , the main part of the support comprises a third receiving means 90. The third receiving means 90 comprises for example a tab extending in a longitudinal and transverse plane or substantially in a longitudinal and transverse plane. The third receiving means 90 preferably comprises a threaded rod 91, for example extending vertically once the support is mounted on the body. Alternatively, a hole can be provided in the tab 90 so as to allow fixing by bolt for example or an added nut can be provided to ensure fixing via a screw. The third receiving means 90 ensures the attachment of a resistance type liquid heating system (for example at 12V voltage) making it possible to heat a liquid to warm the battery if necessary. Preferably, the water circulating at such a heating system is delivered by the pump 5. Advantageously, such a heating system is fixed, assembled on a support 94 provided with a hole to allow its fixing. Preferably, such a heating means makes it possible to increase the temperature of a liquid intended to be sent to a traction and/or propulsion battery of the vehicle, for example to heat the battery in cold weather and/or to facilitate its recharge in cold weather and/or to limit its discharge.

A mode of execution of a method of assembling the body 2 will now be described.

As a reminder, the body 2 preferably comprises the spar 3 and the crosspiece 4.

The method comprises a step of mounting the pump 5 comprising the first vibration damping means 6 on a secondary part 30; 30' from a support 10. Advantageously, this assembly step is carried out using a press, the effort required to fit the first means 6 onto the secondary part being significant. Once this insertion or fitting has been carried out, we obtain the assembly 35 comprising the pump 5, the damping means 6 and the secondary part of the support.

Preferably, the step of obtaining the assembly 35 is carried out at the edge of the line, for example in hidden time, for example on a separate station equipped with a suitable press, so as not to delay the main chain of production of vehicles with this tedious and possibly time-consuming step.

Simultaneously with this step, or substantially simultaneously with this step, or following this step, or previously to this step, a step of assembling a main part 20 is carried out; 20' of support 10 on the spar 3 and/or on the crosspiece 4. For example, this assembly or fixing step is ensured by screwing the two screws 11, as specifically illustrated in the , preferably using a screwdriver. For example, a pre-retaining means (not illustrated) is provided between the main part of the support and the spar and/or the crosspiece. Thus, the operator can pre-position the main part of the support before inserting the screws 11 through the main part and screwing them.

Note that Figures 8, 9 and 10 are only illustrations. Indeed, it is appropriate to assemble and fit the pump (more precisely the damping means 6 of the pump 5) onto the secondary part before proceeding with fixing the secondary part to the main part. Indeed, without this preliminary step, it becomes very difficult, if not impossible, to fix the pump on the secondary part, this operation requiring the use of a press and/or specific lubrication. Such a press requires space which does not make it possible to insert the pump 5 on the secondary part 30, 30' already assembled with the main part 20, 20' of the support 10. Moreover the fixing means 40 , 40' removable is provided to allow the screwing of the screws 11 for fixing the support 10 on the spar and/or on the crosspiece, in this case the fixing of the main part.

Indeed, an assembled support 10, that is to say main part 20, 20' fixed with the secondary part 30, 30' equipped with the pump 5, the pump and/or the secondary part and/or the means 6 damping comes into interference with a socket 60 of a screwdriver for screwing screws 11, as is illustrated in the .

After the step of fixing the main part on the spar and/or on the crosspiece, we proceed to a step of mounting the assembly 35 on the main part 20, 20'. Concerning the embodiment, this assembly step is ensured by a translation from top to bottom of the assembly 35 so that the holes 31, 33 are housed around the two threaded rods 21. Preferably, concerning the variant, in particular in the case of blocking means 52, 53, the assembly 35 is also brought from the top.

To do this, in the embodiment, we screw in the two nuts 41.

In the alternative embodiment, the nut 41' is screwed onto the screw 25' with the interposition of the second vibration damping means 45. Preferably, beforehand, the means 45 are placed, inserted and fitted into the hole 21' made in the base 22' of the main part 20'. As a reminder, in the variant of the embodiment, we ensure that the first and second blocking means 52, 53 are correctly placed in relation to each other, or even one inside the other if necessary. , so as to ensure optimal placement of the secondary part 30' relative to the main part 20'. Preferably, this placement is such that it limits, or even avoids, any subsequent contact between the two parts 20', 30' during use of the vehicle, despite the vibrations emitted by the pump 5.

Then, preferably, we proceed to a step of fixing the pipe 8 on the main part of the support 10, at the level of the first receiving means or tab 80, in particular after having fixed the clip 82 on the threaded rod 81 so as to insert the pipe in the clip 82. Then, or beforehand, we carry out a step of fixing the solenoid valve 7 on the main part of the support 10, at the level of the second receiving means or tab 70, in particular by fixing the plate 74 ( the solenoid valve having been previously fixed on the plate 74) via the two screws 75 cooperating with the added nuts 71. Then, or previously, we proceed to a step of fixing the heating system 9 on the main part of the support 10, at level of the third receiving means or tab 90, in particular by inserting the support 94 of the heating system onto the threaded rod 91 and by screwing the nut 95 onto the threaded rod 91 to ensure that the support 94 is maintained in position on the tab 90 .

In summary, the solution concerns a water pump support offering improved accessibility for assembly due to its two-part design that attaches to each other in a removable manner. Thanks to the division of the support into two parts, the step of obtaining the pump and secondary part assembly requiring special tooling can be anticipated, and/or has no impact on the duration of the assembly of the support. the box. Fixing the main part is easy because the operator has plenty of space to approach and then screw in the screws 11, for example via the socket 60 and a suitable screwdriver.

In addition, the addition of reception means or legs 70, 80, 90 makes it possible to lower costs. Indeed, these receiving means ensure the fixing of elements such as for example the braking circuit pipe and/or the air conditioning solenoid valve and/or a heating system for the thermo-management of a battery. This eliminates the need to design, manufacture and assemble other specific supports for these elements. In addition, the solution makes it possible to reduce the number of parts making up the body, which further contributes to reducing costs.

The solution makes it possible to simplify the connections, in particular for one or more cooling and/or heating circuits, between the elements supported by the support 10 and elements supported by the body despite the complexity of such circuits. This is particularly the case for electric vehicles. The two-part support allows the water pump to be fixed in a more accessible manner, higher than in the state of the art, which facilitates its connection. In addition, we obtain a saving of time for this connection step while reducing the arduousness of this position on the assembly line.

As a reminder, the damping means 6 makes it possible to avoid the transmission of vibrations due to the operation of the pump towards the spar 3 and/or towards the reinforcing crosspiece 4 of the apron, and consequently, towards the body.

Thanks to the variant of the embodiment integrating the second filtration means 45, any vibrations of the solenoid valve 7 are attenuated or even do not reach the support 10, and little or not the body. As mentioned, it is preferable that the second blocking means 53 extending from, or provided in, the secondary part does not press on the first blocking means 52 extending from, or provided in, the main part, or vice versa, in order to avoid any transmission of vibrations between the secondary part and the main part at this level. As a reminder, any vibration received by the main part of the support is transmitted to the spar 3 and/or to the crosspiece 4, that is to say to the body, which should be avoided for the purposes of comfort for the occupants of the vehicle.

The solution still makes it possible to reuse many elements common with a vehicle with a thermal or hybrid engine, in particular in terms of fixing points for the water pump at the level of the spar and the crossmember.

Thus, despite the vibrations emitted by the water pump, in particular due to a high rotation frequency, these vibrations are filtered or even eliminated so as not to reach the body. This results in a very low noise level in the passenger compartment, which is particularly sought after in an electric vehicle. This results in increased comfort for the occupants. The solution makes it possible to anticipate the problem of vibrations or vibration phenomena upstream in order to avoid any subsequent modifications at the end of vehicle development. Obviously the variant of the embodiment which includes double filtration, that is to say two stages or levels of filtration (first means 6 and second means 45), maximizes the vibration or noise attenuation performance.

Thus, although elements of the circuit are arranged on the body and elements of the circuit are arranged on the support, the connections or junctions are easy to make. It then becomes possible to reuse bodies or body elements originating from or designed for vehicles with thermal or hybrid engines.

As a side note, the solution therefore achieves the desired objective of facilitating the attachment of a water pump while simplifying connections at this level, saving time on the assembly line and lowering costs, and presents the following advantages:
- it can be used in other types of vehicles including elements to be fixed in confined areas,
- it can be used to fix other organs than those previously mentioned.

Although the spar shown is a right front spar, the solution can be adapted for a left front spar. Alternatively, the solution can be adapted for a spar arranged at the rear of the vehicle, a rear cross member being able for example to replace the deck reinforcement cross member if necessary.
