Definitions
- the present invention relates to a hydrokinetic coupling device with locking clutch 5 of the type described in French patent application No. 98.04216 of March 31, 1998.
- such a hydrokinetic coupling device comprises a turbine wheel which can be made integral with a driven shaft and housed in a housing.
- impeller wheel with which it can cooperate, for the hydrokinetic transmission of a torque to said driven shaft, from a driving shaft which can be made integral with said impeller wheel, the turbine wheel and / or the wheel of impeller being constituted in the form of a wheel
- Such hydrokinetic coupling devices can be applied in particular to motor vehicles, and as is known in such applications the
- the invention relates more precisely to the constitution of a wheel comprising an outer and / or inner toroidal part as well as blades which are produced therefrom.
- this impeller can be used in a hydrokinetic coupling apparatus of the kind in question, as an impeller or turbine wheel, for example molded from a synthetic material.
- the paddle wheel is made in three parts. It is desirable to simplify this wheel.
- the invention therefore relates, in addition to the constitution of this impeller and of its different parts, the constitution of said inner toroidal part, the assembly of the outer and inner toric parts between them by means of the vanes, the connecting means of the O-ring part external to the hub, and finally the assembly of said impeller with the cover when it is a question of the impeller, the various aims of the invention being in any case obtaining: a gain of weight with synthetic materials which replace steel, a reduction in costs, the realization of a turbine or an impeller in one or two pieces, being simplified in particular by reduction of the number of operation during the realization compared to the case where these components are made of steel, a gain in terms of fluid losses compared to a conventional steel construction (leaks between the blades and the toroids), and a gain in efficiency for the device, the m oulage of the blades of turbine or impeller being able to allow to realize a more complex shape of the blades resulting in a better circulation of the fluid.
- a hydrokinetic coupling device of the type defined at the start is characterized in that the blades and said toric part are molded in part from a synthetic material, being a thermoplastic material , a thermosetting material or an alloy of materials synthetic, these materials can be reinforced with resistant fibers.
- said resistant fibers are glass, carbon, "Kevlar” fibers, etc.
- the molded turbine wheel has a thickened peripheral part, which allows it to contain arcuate housings for the springs which ensure its connection with the clutch disc.
- a blade and toroidal sub-assembly are produced, in a simple and economical manner, which makes it possible to reduce the number of parts and to easily produce a synthetic plastic sub-assembly, knowing that it is very difficult to produce a wheel, in particular a turbine, in one piece. Indeed the mold is then very complex.
- the blades can have a more complex shape and therefore be more efficient from the dynamic point of view.
- the wheel does not have an inner torus.
- a stabilizing means distinct from the toric part, is provided on the free side of the blades to stabilize them.
- the means consists of a crown or a toothed disc, folded or not, to maintain the spacing between the blades and stabilize it.
- this means consists of the other toric part.
- This other part can be metallic or made of synthetic material.
- the blades are inclined so as to allow demolding with a relative helical movement between the mold and the part. This operation is easily achievable. When the blades are straight, demolding can be carried out axially.
- the toroidal part molded with the blades can be the internal or external toric part.
- the blades came partly from the internal toric part and partly from the external toric part and are then assembled together at their free ends, for example by gluing, ultrasonic welding, by indirect heat input, for example a laser welding. It is thus possible to obtain blades of more complex shape and even more efficient from the hydraulic point of view.
- FIGs 1 to 12 and 14 of the accompanying drawing are all views in axial half-section of a wheel. with blades according to the invention, suitable for constituting an impeller or turbine wheel in a hydrokinetic coupling device, FIG. 13 being a perspective view of the blade-outer toroid assembly of FIG. 1, while Figure 15 is a partial axial sectional view of such a wheel.
- FIG 1 there is shown an embodiment in which the impeller, for example a turbine wheel 1, is integral with a steel hub 2 and comprises an outer shell or O-ring part 3 of which are integral with the blades 4 , the assembly 3-4 being of synthetic material molded in one piece and fixed by a crown of rivets 5 (or bolts) on a part thinned external device 6 of a web 7 that the hub has.
- the hub 2 is internally grooved for its rotational connection to the driven shaft.
- the hub 2 constitutes the output element of the hydrokinetic coupling device.
- FIG. 2 represents an analogous embodiment in which the common references have the same meaning as in FIG. 1.
- the impeller further comprises an internal toric part 8, here classic, for example made of synthetic material and fixed on the part outer toroid 3 via the blades 4, as will be indicated below, so as to secure said vanes 4 to each other, on the side opposite to the outer toric part 3.
- the inner toric part 8 therefore constitutes a means stabilizer provided on the free side of the blades to stabilize them and maintain the spacing between them.
- FIG. 3 represents a variant of the embodiment of FIG. 2 in which, to avoid fixing by rivets or bolts, the steel veil 7 of the hub 2 has in its peripheral part 6 thinned for example a series of regularly spaced holes 9 which during molding are filled with the synthetic material of the outer toric part 3, for example overmolding this in a manner known per se.
- Figures 4 to 6 show the same method of attachment to the hub, with further variants in which the maintenance of the blades 4 on their free side, on the side opposite to the outer O-ring part 3, can be ensured by a toothed crown 10 plastic or steel
- FIG. 4 by a toothed disc 11 made of synthetic material or of steel (FIGS. 5a, 5b), or also by a toothed and folded crown 12, also made of synthetic material or steel ( Figure 6).
- This crown or this disc disposed on the free side of the blades, constitutes the aforementioned stabilizing means.
- the crown 10 has an axial orientation and has the shape of a comb, the teeth of which form spacers between the blades 4 to stabilize the latter.
- the disc 11 also has the shape of a comb with teeth between the blades like the crown 10, but the disc extends transversely.
- the crown 12 has a square shape and therefore has teeth which have a transverse orientation between the blades 4 and are connected to a continuous part of axial orientation, like the crown 10.
- the outer O-ring part 3 and the blades 4 are molded from a one-piece synthetic material. As indicated above, it may be a thermoplastic material, a thermosetting material or an alloy of synthetic materials, these materials being able to be reinforced with resistant fibers, in particular glass fibers, carbon fibers, " Kevlar "etc.
- the outer toroidal part 3 with its blades 4 consists of a synthetic material overmolded on an outer metal shell 13, for example of steel, as this has been shown in FIG. 7, which increases the rigidity of the impeller 1. It is then possible to secure this assembly on the hub 2 by means of an inner edge 14 of the shell 13, welded at 15 to the web 7 of the hub, a circular row rivets 5 (or bolts) ensuring the fixing of the external toric part 3 on this edge 14, outside the peripheral edge of the web 7. The inner toroidal part is secured to the blades 4 of this assembly 13, 3, 4.
- the invention also relates to the different assembly methods which can be used to join the different parts of the impeller 1 together.
- thermosetting or thermoplastic materials or alloys we can proceed by gluing for example with a phenolic glue for thermosetting or thermoplastic materials or alloys, or by welding or any other type of generation of heat as ultrasound, welding by indirect heat input such as laser type welding, electromagnetic field or high frequency currents or by friction, vibration, riveting or riveting for thermoplastic materials.
- connections by metal inserts arranged in the molds which can be welded.
- the assembly of the impeller 1, namely the turbine wheel with the steel turbine hub, and / or the impeller wheel with the pump drive hub also made of steel it can be done by overmolding shown in Figures 3, 4, 5a, 5b and 6 or again by standard riveting ( Figures 1, 2, 7), screwing or bolting.
- the invention also relates, in the case of an impeller, to its assembly with a cover or casing such as that referenced 2 in the basic application.
- the inner O-ring portion 8 may be in one piece with the blades 4 by being molded in one piece from a synthetic material as described above.
- thermoplastic or thermosetting material or of an alloy of synthetic material
- these materials can be reinforced with resistant fibers such as glass fibers, “Kevlar” or carbon fibers.
- the toric part 8 is attached for example by bonding on an outer toroidal part 3 made of steel.
- FIG. 10 there is shown an assembly of vanes 4- inner toric part 8 of impeller of molded monobloc impeller as in FIG. 9 and attached by clipping (or crimping) to an external toric part 3 of steel.
- the outer toroidal part 3 comprises housings 17 into which engage the pins 18 of the blades 4.
- a steel disc 19 with outer edge split at 20 for receiving the blades 4 is fixed by riveting on the external toroidal part or casing 3 for internally retaining the entire impeller 1.
- the rivets referenced at 21 are produced by extrusion of the external toric part 3, which is fixed to the hub 2 by welding, for example by laser, at its internal periphery, at 22. The assembly is thus sealed.
- a turbine wheel 1 consisting of two composite parts: the blade assembly 4-outer toric part 3, and the inner toric part 8, the turbine hub 2 having been here replaced by a fluted 2 'sleeve, overmolded or bonded to an interior insert 23, possibly with a simple radial stop to be produced, for example by machining, molding, embossing or the like.
- the toroid 8 is subject to the external toroid sub-assembly 1 - blades 4 obtained in the aforementioned manner.
- Such an apparatus usually comprises a chamber 11 ′, which comprises a hydraulic fluid whose pressure is greater than that of the chamber 100 so that the linings 18 ′ of the clutch disc 28 are kept apart from the radial wall 2a of the casing of the impeller, so that the torque from the impeller is transmitted to the turbine wheel 1 with sliding, only by hydrokinetic effect in said coupling device, the springs 27 then being inactive.
- the pressure in the chamber 100 is greater than that of the chamber 11, and the linings 18 ′ then come into friction on the radial wall 2a, which then causes the drive of the turbine wheel 1 via folded tabs 19 'and 21' of the disc 28 as well as springs 27.
- the turbine wheel is disengageably connected, by the lining 18 'integral with the piston 28, to the casing part 2a intended to be linked in rotation to the driving shaft, here by threaded parts, one (not referenced) is visible in Figure 14.
- the piston 28 is provided at its outer periphery with folded tabs 19 'and 21' respectively to support the circumferential ends of the springs 27 and to radially retain the springs as described in document FR 98.02808 filed on 03.03.1998.
- the tabs 19 ′, 21 ′ belong to a disc interposed axially between the transverse wall of the casing part and the piston as described in FIG. 1 of this document.
- the rivets can be in one piece with the veil 7 by being made by extrusion.
- the ring of the part 3 is interposed between the veil 7 and a metal ring both crossed by the rivets, the free ends of which are crushed on contact with this metal ring.
- FIG. 1 of the document FR-A-2634849 we see that with solutions of the type of that of FIGS. 7, 9, 10, 12 that it it is possible to weld parts 57 or 62 of document FR-A-2634849 to the external toric part, while having plastic blades.
- the blades can be in two parts each coming from molding respectively with the outer and inner toroidal part as described above.
- the two free ends of the blades are fixed together, for example by gluing, ultrasonic welding, laser type welding, etc. as described above. This makes it possible to obtain blades of complex shape.
