Definitions
- the present invention relates to an assembly comprising several motor vehicle fluid control units, as well as a motor vehicle comprising such an assembly.
- Certain motor vehicles may comprise at least two units for regulating a cooling fluid, pumps in particular, each comprising an electric motor having parallel axes of rotation, which are fixed to the powertrain in order to manage the thermal flows of the engine and of transmission.
- a known type of assembly with two pumps presented in particular by the document FR-A1 -3065511, comprises a first elongated leg, and a second elongated leg fixed to the base of this first leg, these legs made of stamped sheet metal having of constant cross-section with two undulations.
- Each pump comprises a casing having a slot having a constant section formed in a plane perpendicular to the axial direction, which extends over a length of this casing, receiving in an adjusted manner one of the legs of the support inserted therein.
- a problem that arises is that it is difficult to adjust the vibration isolation between these pumps and the support, in order to avoid transmission of vibrations and noise.
- this support comprises two metal parts that must be assembled together, requiring the management and supply of these parts, then a time for the assembly of these parts using the tools necessary to tighten this assembly. These manipulations lead to risks of incorrect assembly, such as insufficient tightening. Manufacturing, parts management and the necessary assembly time entail particular costs.
- Another type of known assembly with two pumps comprises for each pump a plate receiving in a bore the body of this pump, these plates comprising on one side complementary shapes which allow a interlocking between them in order to link them to secure the two pumps.
- each plate has a slot which extends axially through this plate, having a constant section.
- a unique mount has two tabs that fit into the slots in the two pump plates.
- connections between the two plates of the pumps have dimensions which can limit the bringing together of these pumps, one obtains a relatively large overall size of the assembly.
- This assembly is more difficult to install on a powertrain, in an engine compartment having a generally reduced space to optimize the volumes of the vehicle.
- the two plates are also two components resulting in manufacturing and supply costs, and requiring assembly time between them.
- the object of the present invention is in particular to avoid these problems of the prior art.
- An advantage of this assembly is that the plate forming a single piece of the support, by bringing the holes receiving the bodies of the regulation units as close as possible, these bodies can be arranged as close as possible to each other, without having to provide connections of two parts of plates between they. In this way, the bulk of the assembly is reduced, and it facilitates its integration into the powertrain of the vehicle.
- connection between the two regulation units is secured by the single plate receiving them, the number of parts is reduced and assembly is simplified, which reduces manufacturing costs.
- the assembly with regulating units according to the invention may also comprise one or more of the following characteristics, which may be combined with each other.
- each bore has, in a plane transverse to the axes, a section which is constant over the length of this bore.
- each hole forms a circle comprising regularly distributed hollows on the contour.
- one face of the plate has, on the contour of each hole, grooves each receiving a boss protruding from the outer contour of the regulation unit bodies.
- the plate has slots for receiving fasteners which have a constant cross section.
- the plate may have three spaced apart slots.
- the slots can form holes which pass through the plate.
- the plate comprises elastomeric materials.
- the plate may in particular comprise several elastomeric materials having different stiffnesses.
- the invention also relates to a motor vehicle comprising at least two coolant pumps which form part of an assembly comprising any one of the preceding characteristics.
- FIG. 1 presents a complete assembly according to the invention comprising two pumps
- FIG. 2 is a view of the front face of the support plate alone of this assembly
- FIG. 3 is a view of the rear face of this plate;
- FIG. 4 is a rear side view of the assembly attached to a powertrain;
- FIG. 5 presents a complete assembly showing several possible angular orientations of each pump.
- Figure 1 shows an assembly comprising two units for regulating the circulation of fluid, in particular pumps 2, each having an axis of rotation A, these axes parallel to each other comprising a side called by convention front, indicated by the arrow AV.
- Each pump 2 comprises an outer body 4 comprising on the front face an axial orifice 6 and a tangential orifice 8 for the circulation of the fluid in this pump.
- each pump comprises electrical connectors 10 making it possible to supply them with current on demand, to regulate the circulation of cooling fluid in a motor vehicle, in particular an electric or hybrid vehicle.
- Figures 1, 2 and 3 show a support formed of a single plate 20 with two parallel faces 26, 30 perpendicular to the axes A, comprising two through-holes 22 which each receive a pump body 4.
- the constant section perpendicular to the axes A of each hole 22, forms a circle comprising regularly distributed hollows 24 on the contour.
- each pump 2 has a substantially circular outline comprising a series of axial teeth which fit into a bore 22 of the plate 20 so as to achieve both centering and alignment of this pump, and locking in rotation around its axis thanks to the teeth wedged in the hollows 24.
- Each pump body 4 comprises four bosses 12 which extend axially, protruding from the substantially circular outer contour of this casing, each receiving a screw 14 parallel to the axis A making it possible to clamp together different parts of this body stacked axially.
- the front face 26 of the support plate 20 comprises for each bore 22 four radially oriented grooves 28, distributed around this bore over a small thickness of the plate, each receiving one end of a boss 12 which fits slightly into this front face. .
- the ends of bosses 12 fitted in the grooves 28 also avoid arranging each pump 2 with an incorrect angular orientation in its bore 22.
- the two pumps 2 are arranged as close as possible to each other, with a minimum radial distance between their two bodies 4, comprising a reduced thickness of material 32 between the two holes of this plate 22.
- the use of a same plate 20 receiving the two holes 22 avoids providing a connection between two separate supports. In this way, the overall size of the assembly is reduced, and its installation in the engine compartment of the vehicle is facilitated.
- the rear face 30 of the support plate 20 comprises a slot with a curved section 34 having two undulations, which extends parallel to the axis over a large part of the thickness of this plate, partially opening onto the front face 26 .
- Figure 4 shows a fixing 40 formed by sheets folded and assembled together, fixed to a power unit 42, having three elongated legs parallel to the axes A which each fit in the curved slot 34 or in one of the slots straight 38.
- the spacing of the slots 34, 38 between them provides rigidity and limits the stresses in the fastener 40.
- a complete assembly comprising the support plate 20 receiving the two pumps 2, which can be prepared for example by a supplier.
- the complete assembly is then mounted on the vehicle with the aid of the fixing 40 comprising a single piece, which simplifies supplies, and reduces the risks of incorrect assembly as well as assembly times on this vehicle.
- the support plate 20 is advantageously made by molding a material having a certain flexibility, calculated to dampen the vibrations emitted by the operation of each pump 2, which avoids transmitting these vibrations to the powertrain and to the body of the vehicle. preventing the propagation of noise.
- the flexible material of the support plate 20 also makes it possible to prevent the transmission of vibrations coming from the powertrain to the pumps 2, by avoiding loosening, in particular of the electrical connections 10.
- the support plate 20 may comprise different materials having different hardnesses or stiffnesses, in particular elastomers assembled by successive overmouldings, which make it possible to respond, according to the shapes of the part, to mechanical strength and vibration isolation constraints.
- Hardness is related to stiffness in the sense that as hardness increases, stiffness also increases accordingly.
- the support 20 would have a first part of a first material having a first stiffness surrounding the bore 22 and a second peripheral part surrounding the first part of a second material having a greater stiffness than that of the first material.
- FIG. 5 shows the same support plate 20 comprising bores 22 able to receive, thanks to the circular contour and the succession of regularly distributed hollows 24, the pump bodies 4 in different angular positions.
- This plate 20 forms a standard that can be used on a variety of vehicles.
- regulating units can be provided on the plate 20, each occupying a bore 22.
- These regulating units can comprise pumps 2, or other equipment used for regulating the circulation of fluids in the vehicle.
