Definitions
- the present invention relates to an aerothermal module implantable on a tourism type vehicle, light utility and the vehicle comprising such a module. It also relates to a mounting method on a motor vehicle of an aerothermal module with such a new implantation.
- radiator and fan unit also referred to as "GMV” in the following text
- a condenser if the vehicle is equipped with an air conditioning, and a charge air cooler, if the vehicle is turbocharged.
- This aerothermal module is located, conventionally, in front of the front block of the vehicle, between the shock beam and the powertrain (also referred to as "GMP" in the rest of the text), according to a layout called “ in facade ", the various elements of the aerothermal module being arranged substantially vertically against each other.
- This front layout has the disadvantage of requiring a relatively large carrier structure length between the center of the front wheel and the front end of the vehicle. This length has the consequence, on the one hand, to increase the overall length of the vehicle and, on the other hand, to increase the front overhang. Too long a length of this overhang front detracts from the "style", the aerodynamics, the mass and the cost of the vehicle, the radius of turning between walls, and reduces the angle of attack, c that is to say the maximum inclination of the ascending slope that can approach the vehicle without damaging the bottom of the body. To overcome one or more of these difficulties, it has already substantially changed the implementation of the aerothermal module, or at least one of the elements that constitute it.
- a motor vehicle in which the radiator is disposed transversely to the direction of travel and is inclined in the vehicle, so that the plane of inclination of the radiator is oriented obliquely from top to bottom in the direction of travel.
- a spare wheel Above the radiator is a spare wheel, which is covered by the hood wall.
- the document US 2006/0103127 A1 describes a motor vehicle, which comprises two longitudinal members and a structure fixed on the longitudinal members so as to define a vehicle chassis.
- An independent front suspension is attached to the structure.
- a radiator, a motor and a bumper device are attached to fastening tabs of the structure.
- the radiator does not have a front layout, but is located in a plane inclined to the ground and unfolds largely above the front wheel of the vehicle.
- the engine is located under the seats in the cab and behind the front suspension.
- a hood of the vehicle can be inclined relative to the ground plane, in a plane substantially parallel to the plane of the radiator, so as to improve the aerodynamic shape of the cabin and the visibility of the driver.
- This allows the radiator to oscillate about a substantially horizontal axis and transverse to the vehicle so that this oscillation can tilt, during the mounting phase, the radiator according to the type of vehicle on which it is mounted.
- a single type of radiator is adaptable to various types of vehicles that have different chassis and engines simply by changing the inclination of the radiator. Then once the inclination chosen, we fix the radiator which can not oscillate then.
- the journals serve as connectors for the entry and exit of the coolant.
- the inclination therefore allows adaptation to several types of engine but the radiator is still positioned at the front of the vehicle in front of the engine and, moreover, the positioning of the radiator inlet and outlet is imposed by the positioning of the oscillation axis, imposing and therefore limiting the connection architecture.
- a motor vehicle which comprises an aerothermal module placed above the powertrain of the vehicle, in the space between the fictitious surface called “technical hood" and the surface of the powertrain increased its deflection , so as to reduce the distance between the powertrain and the impact beam at the front of the vehicle and, consequently, to reduce the front overhang of the front block of the vehicle.
- this aerothermal module and placed above the powertrain masks some organs of said group while they must remain accessible to the fitter in the factory, the after-sales operator and / or the customer.
- the aerothermal module must be able to be retracted in a simple manner by the customer and / or the operator without notably requiring disassembly and removal of said module. Indeed, such disassembly must be made taking care not to damage the elements of the module or to apply too much force to the water hoses may be sources of leakage.
- the object of the present invention is therefore to provide an aerothermal module that can be mounted articulated above the powertrain of a motor vehicle, avoiding the aforementioned drawbacks of articulated implantation with the aid of an additional framework, while being simple, economical, and facilitating the maintenance of the module.

- the hinged assembly of one of the cooling equipment which incorporates fastening means allowing it to pivot on the vehicle and which is assembled with the other cooling equipment, allows the articulated assembly of the entire module. without the need for a frame.
- the module according to the invention therefore proposes to limit the number of parts required in this type of installation thus promoting the simplicity of implementation and assembly while allowing accessibility to the powertrain, the raised position called "after-sales" leaving access to the engine and to easily perform routine maintenance of the engine and / or module without having to dismount it or open the various circuits of said module.

- locking means in the module position the locking being reversible, said means for locking the module at least in the normal operating position and, optionally also in position "after-sales" statement.
- the locking in position of the module on the vehicle keeps the aerothermal unit in the correct position, the articulation of said module relative to the vehicle being prevented and this, whatever the driving conditions.
- the reversible locking allows when necessary to raise the module and possibly maintain it in this raised position.
- the locking means consist of at least one coupling member arranged on one of the cooling materials constituting the module such as the radiator, preferably the opposite of the hinge pin, and cooperating with a complementary member of the vehicle structure to allow the coupling of said module with said structure in the normal operating position, and its decoupling for its drive to the raised position "after-sales" of said module.

- This module 1 is located above the powertrain or GMP, general reference 8, in a space between the cover 10 of the vehicle and the GMP 8, specifically in the space between the fictitious surface called "technical hood ", Represented by the line 9 in Figure 1, and the surface of the GMP increased its clearance, said surface of the" GMP discussed ", shown schematically by the line 1 1 in Figure 1.
- hood is meant, in a conventional manner, the imaginary surface, located under the lining of the cover 10, which delimits with the latter an exclusion zone, in which is excluded any implantation of a rigid component , so as to take into account the possible consequences of a pedestrian impact.
- the “technical hood” 9 is the design limit sufficiently far from the hood 10 to be compatible with the regulations on pedestrian impact.
- GMP discussed 1 1 means the outer surface of the GMP increased its clearance space, the deflection being due mainly to the stresses of the road.
- the new implantation of the aerothermal module 1 above the GMP 8 substantially reduces the distance between the GMP 8 and the shock beam, at the front end of the vehicle and, consequently, reduces the carrier.
- the front end of the vehicle that is to say the distance between the front end of the vehicle and the center of the front wheel (not shown).
- the aerothermal module 1, shown with the condenser 4, the radiator 2 and the fan assembly 3 is hingedly mounted on the vehicle.
- the radiator 2 comprises means adapted to articulated mounting said radiator on a vehicle structure about an axis referenced X, which may be, for example, a substantially horizontal and transverse axis.
- the radiator 2 may be mounted articulated about an axis contained in a longitudinal vertical plane of the vehicle.

- the members 13 of each housing 5 engaged in their respective bearing 12 define at one end of the radiator 2, a substantially horizontal axis of rotation X and transverse around which is provided the articulation of the radiator 2 on the vehicle.
- the radiator 2 is provided at its end opposite to that provided with the axis of rotation X, at least one coupling member 14 of said radiator 2 with the structure of the vehicle.
- This coupling member 14 cooperates with a complementary coupling member 15 provided on the vehicle structure.
- This complementary coupling member 15 cooperates, for example, on the one hand with the coupling member 14 and on the other hand is secured, for example by screwing, to the structure of the vehicle, here a cross member 16 so as to block the radiator 2 in normal operating position or rolling position.
- the complementary coupling member can also be attached to the vehicle, and for example present a housing in which is positioned by force the coupling member. All other organs allowing coupling / decoupling (hooks, tongues, etc.) are also conceivable.
- the complementary coupling member 15 of the cross member 16 is disassembled, for example by simply unscrewing it, and it is uncoupled from the coupling member 14 of the radiator 2.

- a configuration given by way of example may be related to environmental constraints of the vehicle.
- the aerothermal module 1 being fixable on the vehicle through the radiator 2, thus obtaining a great freedom to propose different architectures of the elements of the module 1 in particular with regard to the connection ends of the various conduits. So, we can use within a module according to the invention, different elements such as a radiator provided with two end pieces on the same side or two ends on each side, etc.
- the water conduits, refrigerant and degassing are suitable and allow to put the aerothermal module 1 in position "after-sales".
- the inclination of the radiator 2 relative to the vertical is minimal, so as not to penalize the performance of the exchangers.
- the cooling material consisting of "hard” elements, is tangent to the technical hood 9 built from the style hood 10, itself consistent with the style and low visibility criteria.
- a fresh air supply duct fixed on the front face, can be provided to allow to supply the cooling equipment with the appropriate air velocities.
- This sheath is made of flexible material and, thanks to this flexibility, can be partially installed above the technical hood 9.
- Foams (not shown) provide a good seal between the fresh air supply duct and the radiator 2 and / or the condenser 4.

- the implementation described above of a motor vehicle aerothermal module has the advantage of allowing a gain in architectural performance of the front block of the vehicle. This yield essentially results in a sharp reduction in the distance between the impact beam and the GMP 8, therefore a sharp reduction in the technical front overhang of the vehicle.
- This front overhang technical front can be reduced, as mentioned above, about 230 mm for example with the new implementation of the module 1 above the GMP compared to the conventional layout in front.
- Such a gain in length then allows:
