Description

[0001] TITLE: Arrangement for fixing a breather in a vehicle

[0002] The invention relates to an arrangement for fixing a gearbox breather in a vehicle, particularly in the front structure of the vehicle. The invention also relates to a vehicle equipped with such an arrangement. The invention finally relates to a method for mounting an arrangement according to the invention.

[0003] In the automotive industry, the front structure of vehicles, and more specifically the engine compartment, is subject to numerous spatial constraints, meaning that the space available for installing new components or rearranging conventional components is reduced. This problem is particularly present with the evolution of vehicles from traditional, internal combustion engine powertrains to electric or hybrid powertrains.

[0004] Conventionally, in order to balance the pressure inside a gearbox casing, it is necessary to integrate a vent, also called a "breather". A breather includes a valve that systematically causes air to enter an environment where a vacuum occurs. In order to ensure proper operation of such a breather, it must be implemented under specific conditions. In particular, in order to prevent the entry of foreign bodies into the gearbox housing, or casing, such as dust and / or insects, it is known to equip the breather with a protective cap. Also, to prevent water intrusion, particularly in countries subject to monsoon risks, the breather outlet must conventionally be installed at a height, i.e. at a vertical position relative to the ground, predefined and suitable.In the case of thermal vehicles, the thermal engines have a vertical footprint allowing vertical installation at more or less suitable heights, the gearbox breather can then simply be fixed to the housing of the thermal engine. Such a principle cannot, however, be transposed to electric vehicles, on the one hand because of the smaller vertical footprint of electric motors and on the other hand because of the different footprint of the front structure of the vehicle, for example the presence of a crossmember or beam extending through the engine compartment, making it impossible to raise a breather from the housing of the electric motor, i.e. vertically above the electric motor.

[0005] The present invention falls within this context and aims to propose an arrangement allowing the breather to be installed at a suitable height and also allowing predefined sealing constraints to be met. The present invention also aims to propose an arrangement which can be implemented at a lower cost and which is simple to install within the vehicle.

[0006] The invention relates to an arrangement for fixing a gearbox breather of a vehicle, the arrangement comprising at least one engine, a gearbox, a breather connected to said gearbox and comprising a tube, one free end of which forms an air inlet, a first element and a second element of the front structure of the vehicle, distinct from each other, the arrangement further comprising at least:

[0007] - a first point of attachment of the tubing, made on an engine housing

[0008] - a second point of attachment of the tubing made on the first element of the front structure, fixed relative to said first element, and a third point of attachment of the tubing made on a tab included in a rectilinear portion of the second element of the front structure, at least the second point of attachment being configured to prevent the transmission of vibrations and / or stresses from the engine to the free end of the tubing and the second point of attachment being interposed between the first point of attachment and the third point of attachment.

[0009] The first attachment point may be made at a removable multi-function attachment bracket, attached to the engine housing, configured to hold at least one cable or pipe, in particular a vehicle power supply cable.

[0010] In particular, the tab and the second element of the front structure of the vehicle may form a single-piece assembly. Optionally, the tab may comprise at least one reinforcement and / or an oblong orifice capable of receiving a breather attachment member, such as a clip or staple.

[0011] The breather may further comprise a cover equipped with a filter arranged on the free end of the tubing, the third attachment point being able to be made at the level of said cover.

[0012] In particular, the second element of the front structure of the vehicle may be an element of the frame of the technical front of the vehicle or a feed chute of a windscreen washer reservoir.

[0013] The first element of the front structure of the vehicle may be a nozzle of a fan arranged on the front face of the vehicle or a fixed element of the body structure, such as a side member.

[0014] The invention also relates to a motor vehicle, in particular an electrically powered vehicle, comprising an arrangement according to the invention. In particular, within said vehicle, the free end of the breather tube may be arranged at a height, defined along the vertical direction, greater than or equal to 650 mm, or even 670 mm relative to a ground on which the vehicle (100) rests.

[0015] The invention finally relates to a method of mounting an arrangement according to the invention, successively comprising:

[0016] - fitting the breather pipe onto the gearbox;

[0017] - fixing the first fixing point of the tubing on the engine housing;

[0018] - fixing the second fixing point of the tubing on the first element of the front structure of the vehicle;

[0019] - fixing the third attachment point of the pipe on the second element of the front structure of the vehicle.

[0020] Other details, characteristics and advantages will emerge more clearly on reading the detailed description given below, for informational and non-limiting purposes, in relation to the various examples of embodiment illustrated in the following figure:

[0021] Figure 1 is a simplified schematic representation of an exemplary embodiment of a gearbox breather attachment arrangement produced according to a first embodiment.

[0022] Figure 2 is a top view schematic representation of the arrangement shown in Figure 1.

[0023] Figure 3 is a perspective representation of a breather attachment point implemented on a windshield washer nozzle.

[0024] Figure 4 is a perspective representation of the breather attachment point implemented on the windshield washer nozzle.

[0025] Figure 5 is a simplified schematic representation of an exemplary embodiment of the gearbox breather attachment arrangement made according to a second embodiment. Figure 6 is a top view schematic representation of the arrangement illustrated in Figure 5.

[0026] Figure 1 schematically illustrates an exemplary embodiment of an arrangement 1 for fixing a breather 2 of a gearbox 3 within a vehicle 100, in particular a motor vehicle, such an arrangement 1 being arranged at the front structure of a vehicle 100. The vehicle 100 considered is particularly a motor vehicle with an electric motor. Alternatively, the arrangement 1 according to the invention can be applied mutatis mutandis to vehicles 100 with a thermal motor comprising a thermal engine or to vehicles 100 with a hybrid motor comprising a thermal engine and at least one propulsion battery, also referred to as a drive battery. The vehicle 100 considered can, for example, be a private vehicle or a utility vehicle.

[0027] Figures 1 to 6 illustrate different examples and embodiments of the arrangement 1 according to the invention. By convention in the description below, the direction in which the motor vehicle 100 moves in a straight line is defined as being the longitudinal direction X. The direction perpendicular to the longitudinal direction and located in a plane parallel to the ground is called the transverse direction Y. The direction perpendicular to the directions X and Y is called the vertical direction Z. Thus, a direct reference frame XYZ is defined as shown in Figure 1, conventionally implemented in the automotive environment. The terms “top” and “bottom” or “upper” and “lower” are understood in their general sense, the terms “bottom” and “lower” designating a greater proximity to the ground. Also, the terms “first” and “second” are intended to distinguish similar elements and not to define a hierarchy within said elements.Generally, the arrangement 1 according to the invention comprises at least one motor 4, for example an electric motor 4, a gearbox 3, a breather 2 connected to said gearbox 3, a first element 5 and a second element 6 of the front structure of the vehicle 100, distinct from each other.

[0028] The breather 2 is a valve system configured to allow air to enter an environment where a depression occurs, in this case in the gearbox 3. The breather 2 comprises a tube 21, which is connected to the gearbox 3 at a first end. A second, free end of said tube 21 comprises an air inlet.

[0029] The arrangement 1 according to the invention particularly comprises at least three distinct fixing points arranged along the tubing 21. The term "fixing point" is understood to mean a fixing interface between the breather 2, in particular the tubing 21, a fixing member 7 as further explained below and a component serving as a support for said fixing member 7. At least one of said points is particularly configured in order to prevent the transmission of vibrations and / or stresses originating from the engine 4 to the free end of the tubing 21. In particular, at least two fixing points are configured in order to prevent the transmission of such vibrations and / or stresses. Indeed, during operation of the vehicle 100, for example in the rolling phase, the accelerations and decelerations of the engine 4 result in movements and vibrations thereof.As illustrated in Figure 1 with the dotted line representations, the pipe 21 of the breather 2 is then stressed by the movements of the engine 4 and the vibrations are transmitted to it. The fixing points described below are particularly intended to prevent such a phenomenon.

[0030] The tubing 21 has a structure that is at least partly curved, in particular at least partly “S-shaped”. The tubing 21 further comprises at least one rectilinear portion at which one of the fixing points is implemented. In particular, the tubing 21 comprises at least as many rectilinear portions as the arrangement 1 comprises fixing points, each fixing point being implemented at one of said rectilinear portions. In this case, in the example illustrated, the arrangement 1 comprises three fixing points and the tubing 21 comprises three rectilinear portions.

[0031] The arrangement 1 comprises a first point 81 for fixing the tubing 21, produced on a housing of the engine 4. In particular, the first fixing point 81 is produced at the level of a removable fixing lug 8, attached to the housing of the engine 4. In particular, the lug 8, and by extension the first fixing point 81, is fixed relative to the engine 4. Preferably, the fixing lug 8 is made of a metallic material. The tubing 21 is connected to the fixing lug 8 via a fixing member 7. The fixing member 7 may in particular be a staple or a clip. Conventionally, the fixing member 7 may, for example, have two curved and articulated arms, said arms being able to close around the tubing 21 of the breather 2. Alternatively, the fixing member 7 may comprise a ring.

[0032] Advantageously, preferably, the fixing lug 8 may be a multifunctional fixing lug 8 configured to hold at least one cable or pipe. For example, the fixing lug 8 may be configured to hold an electrical power supply cable of the vehicle 100, in particular a 12V electrical cable supplying a service battery. The fixing lug 8 being mounted on the housing of the motor 4, it is subject to vibrations and movements.

[0033] At least a second point 82 for fixing the tubing 21 is made on the first element 5 of the front structure of the vehicle 100 and a third point 83 for fixing the tubing 21 is made on the second element 6 of the front structure of the vehicle 100.

[0034] In particular, the second attachment point 82 is a fixed point relative to the front structure of the vehicle 100. By "a fixed point" is meant a point which is not moved, in particular which is not moved with the engine 4 when the latter is in operation as explained above. In particular, such a fixed point aims to limit the transmission of vibrations and stresses along at least a portion of the tubing 21. In this sense, the second attachment point 82 is made at a part of the front structure which is sufficiently strong not to be moved or torn off in the event of extreme stresses on the engine 4.

[0035] The second fixing point 82 is arranged so as to be interposed between the first fixing point 81 and the free end of the tubing 21. The second fixing point 82 is produced by means of a fixing member 7 as previously explained, directly mounted on the first element 5 of the front structure. By “directly” is meant that the fixing member 7 is directly mounted on the first element 5, without any other intermediary. For example, the fixing member 7 can be clipped or screwed at a threaded orifice included in the first element 5 of the front structure.

[0036] The first fixing point 81 and second fixing point 82 thus virtually delimit three distinct segments of the tubing 21 of the breather 2. Here, the term "segment" is understood to mean a portion of a whole, in this case a portion of the tubing 21. A first segment 210 of the tubing 21 is fitted without a fixing collar onto a connection 11 of the gearbox housing 3 and held at the level of the first fixing point 81. This first segment 210 is fixed, or substantially fixed, with the gearbox 3, that is to say relative to the gearbox 3. In other words, during the rolling phase, the first segment 210 may be moved concomitantly with the gearbox 3 depending on the accelerations and decelerations of the engine 4.It is thus not moved relative to the engine 4 but can be moved relative to at least one part of the front structure of the vehicle, in particular relative to the first element 5 and / or the second element 6 of the front structure of the vehicle 100. The first fixing point 81 thus has the function of intermediate fixing of the tubing 21 intended to limit or prevent vibrations or stresses of the first segment 210 so as to prevent any tearing of the tubing 21 from the connection 11.

[0037] The first point 81 and the second point 82 of attachment delimit a second segment 211 of the tubing 21. The second segment 211 can, as explained previously, be subjected to vibrations and stresses. Examples of movements of the second segment 211 are notably illustrated in dotted lines in FIG. 1. The second segment 211 extending only over a part of the length of the tubing 21, the observed deflection, that is to say the amplitude of the movements of said segment due to the vibrations and stresses of the engine 4, is limited.

[0038] A third segment 212 is delimited by the second attachment point 82 on the one hand and the free end of the pipe 21 on the other hand. The third segment 212 comprises in particular the third attachment point 83. The third segment 212 is fixed or substantially fixed relative to the front structure of the vehicle, in particular relative to the first element 5 and / or the second element 6 of the front structure, that is to say that it is little, if at all, subject to the vibrations and stresses of the engine 4, in particular due to the location of the second attachment point 82.

[0039] The second segment 211 of the tubing 21 thus extends within the front structure in order to join the fixed point formed by the first element 5 of the front structure. The second segment 211 may extend in particular along the longitudinal direction X and / or along the transverse direction Y. The second segment 211 may also rise in height, along the vertical direction Z.

[0040] Conversely, the third segment 212 of the tubing 21 extends essentially, that is to say mostly or mainly, along the vertical direction Z until the free end of the tubing 21 reaches a suitable, predefined height. The third segment 212 may also extend at least partly along the longitudinal direction X and / or along the transverse direction Y.

[0041] The arrangement according to the invention advantageously allows positioning of the free end of the tubing 21 at any type of height required and in particular at high heights greater than 600 mm, relative to the ground when the arrangement 1 is equipped within the vehicle, thanks to the solid and resistant fixing implemented.

[0042] According to a first example embodiment of the second attachment point 82, illustrated in figures 1 and 2, the first element 5 of the front structure of the vehicle 100 can thus be a nozzle of a fan 51 arranged on the front face of the vehicle 100.

[0043] According to a second exemplary embodiment of the second attachment point 82, not shown, the first element 5 of the front structure of the vehicle 100 may be a fixed element of the body structure, such as a side member or a cross member.

[0044] It should be noted that, according to exemplary embodiments not shown, the arrangement 1 according to the invention may comprise a plurality of second fixed fixing points 82, as explained previously, arranged between the first fixing point 81 and the third fixing point 83. The plurality of second fixing points 82 may advantageously be produced according to the first exemplary embodiment and / or according to the second exemplary embodiment.

[0045] The third attachment point 83, arranged on the second element 6 of the front structure of the vehicle 100, is produced by means of a tab 9 included in a rectilinear portion 61 of the second element 6 of the front structure. In other words, at least one area of ​​implantation of the tab 9, corresponding to a connection area between the second element 6 of the front structure and the tab 9, is rectilinear.

[0046] Similar to the second attachment point 82, the third attachment point 83 may optionally be configured to prevent the transmission of vibrations and / or stresses from the engine 4 to the free end of the pipe 21. In particular, the third attachment point 83 may be fixed relative to the second element 6 of the front structure. The third attachment point 83 is arranged such that the second attachment point 82 is interposed between the first attachment point 81 and the third attachment point 83 along the pipe 21.

[0047] Advantageously, within the arrangement 1 according to the invention, the tongue 9 and the second element 6 of the front structure of the vehicle 100 can form a single-piece assembly. By "single-piece assembly" is meant that the tongue 9 and at least part of the second element 6 of the front structure are made in one piece so that they cannot be separated from each other without resulting in the degradation, or even destruction, of one or the other.

[0048] The tubing 21 is fixed to the tab 9 at the third fixing point 83 by means of a fixing member 7 similar to what has been explained previously, such as a staple or a clip. According to a first embodiment, illustrated in Figures 5 and 6, which can be implemented with the first exemplary embodiment or the second exemplary embodiment of the second fixing point 82 explained previously, the second element 6 of the front structure of the vehicle 100 is an element of the frame of the technical front face of the vehicle 100. An element of the frame of the technical front face is understood to mean a part of a chassis frame defining the technical front face of the vehicle 100. Such a frame is, in a conventional manner, made from a combination of plastic materials and metallic materials. In this case, preferably, the tab 9 and a portion of the frame made of a plastic material form a single-piece assembly.

[0049] The tongue 9 extends here horizontally, or substantially horizontally. For example, the tongue 9 may originate from a side member of the vehicle 100 and extend towards the engine compartment 4. The tongue 9 may in particular comprise a flat portion comprising an orifice 91 capable of receiving the fixing member 7. For example, the orifice 91 may be an oblong orifice 91. The tongue 9 may also comprise a reinforcement 92 extending transversely to the flat portion of the tongue 9 and configured to ensure the mechanical strength of the tongue 9 and, by extension, the good holding of the tubing 21.

[0050] According to a second embodiment, illustrated in Figures 1 and 2, which can be implemented with the first exemplary embodiment or the second exemplary embodiment of the second attachment point 82 described previously, the second element 6 of the front structure of the vehicle 100 is a chute 62 for supplying a windshield washer reservoir. Conventionally, such a chute 62 extends at least partly along the vertical direction. As explained above, the chute 62 comprises at least one rectilinear portion 61 at which the tab 9 is arranged. The chute 62 can advantageously be made of a plastic material by molding or injection. In this way, the tab 9 can be overmolded onto any type of chute 62 at the rectilinear portion 61 of said chute 62, without it being necessary to adapt said chute.

[0051] In such an embodiment, the tongue 9 extends vertically, or substantially vertically. Preferably, when the arrangement 1 according to the invention is arranged within the vehicle 100, the tongue 9 may be arranged in front of the chute 62. In other words, the chute 62 may be interposed between the chute 62 and the technical front face, or even the first element 5 of the front structure, along the longitudinal direction X. As explained previously, the tongue 9 may in particular comprise a flat portion comprising an orifice 91 capable of receiving the fixing member 7. Optionally, said orifice 91 may be oblong. The tongue 9 may also comprise a reinforcement 92 extending transversely to the flat portion.

[0052] Optionally but preferably, the breather 2 further comprises a cover 10 arranged on the free end of the tubing 21. In particular, said cover 10 is attached and mounted on the free end of the tubing 21. In particular, the cover 10 comprises a filter intended to prevent the entry of particles and dust into the tubing 21.

[0053] When the breather 2 comprises such a cover 10, the third fixing point 83 is produced at the level of said cover 10. The fixing member 7 implemented at the level of the third fixing point 83 then cooperates with the cover 10, which surrounds the tubing 21. The cover 10 as illustrated has an upper end part 101, free, and a lower end part 102. The configuration member cooperates with an intermediate portion of the cover 10, between the upper end part 101 and the lower end part 102. The free end of the tubing 21, not visible, then extends in a space delimited by the cover 10, between the upper end part 101 and the lower end part 102.

[0054] In particular, the cover 10 may comprise a rib 103 extending over all or part of the periphery of the intermediate part of the cover 10 and configured to form a stop for the fixing member 7 along at least one direction, in particular along the vertical direction Z.

[0055] When the breather 2 comprises such a cover 10, at least the free end of the tubing 21 is arranged at the desired, predefined height, all or part of the cover 10 then being able to have a vertical positioning greater than such a height.

[0056] The arrangement 1 according to the invention thus advantageously makes it possible to integrate the strong fixing tab 9 into existing references equipping the vehicle 100 and this at a lower cost. The fixing produced, at a plurality of fixing points, is suitable for significant stresses and vibrations of the engine 4. The arrangement 1 also makes it possible to simplify the mounting of the breather 2, as explained below with reference to the mounting method according to the invention, by eliminating the need to integrate multiple added support or fixing parts.

[0057] When integrated within the vehicle 100, the arrangement 1 according to the invention advantageously makes it possible to arrange the free end of the tubing 21 of the breather 2 at a height, defined along the vertical direction, predefined and adapted. In particular, in order to ensure optimal sealing of the tubing 21, in particular in the case of use in tropical countries, the free end of the tubing 21 is arranged at a height, relative to a ground on which the vehicle 100 rests, greater than or equal to 650 mm, or even greater than or equal to 670 mm. When the tubing 21 is equipped with a cover 10 as explained above, the vertical positioning of the tubing 21 can be carried out as a function of the free end of the tubing 21 and / or as a function of the position of the cover 10.For example, the lower extreme part 102 of the hood 10 may have a positioning, along the vertical direction Z, at a predefined desired height, for example a height greater than or equal to 650 mm, or even greater than or equal to 670 mm. The third fixing point 83, corresponding to the cooperation zone between the breather 2 and the fixing member 7, thus has a vertical position strictly greater than the predefined target height. In this case, the third fixing point 83, in particular the fixing member 7, extends to a height strictly greater than 650 mm, or even strictly greater than 670 mm relative to the ground, for example of the order of 690 mm.

[0058] The present invention also relates to a method for mounting an arrangement 1 as set out above. Said method comprises firstly fitting the tubing 21, particularly the first end of the tubing 21, of the breather 2 onto the gearbox housing 3. The first point 81 for fixing the tubing 21 is then fixed onto the engine housing 4 by means of the attached removable tab 8. For example, the breather 2 can be clipped onto the tab 8.

[0059] In particular, the electrical wiring of at least one electrical power supply cable can be held on this same tab 8. The breather 2 is then arranged in a waiting position on the engine 4. Then, the fixing of the second point 82 for fixing the tubing 21 is implemented on the first element 5 of the front structure of the vehicle 100. Finally, the fixing of the third point 83 for fixing the tubing 21 is carried out on the second element 6 of the front structure of the vehicle 100. Preferably, the various fixings can be carried out by clipping. The present invention thus proposes an arrangement for fixing a gearbox breather making it possible to limit, or even prevent, the propagation of vibrations and stresses from the engine on the entire tubing of the breather.The arrangement makes it possible to ensure a solid and resistant fixing at more or less significant heights on elements conventionally fitted to vehicles. Also, the invention is suitable for implementation in electric vehicles, which are conventionally unsuitable for positioning breathers at a high height. The invention also advantageously allows for a limitation of references and a reduction in costs by using existing elements in the vehicle. In addition, the invention allows for simplified assembly and handling by limiting the number of references involved in the front structure of the vehicle.

[0060] The present invention cannot, however, be limited to the means and methods described and illustrated here and it also extends to any equivalent means or method and to any technically effective combination of such means insofar as they ultimately fulfill the functionalities described and illustrated in the present document.
