    [0001] The present invention relates to a power train with a variable speed transmission device, in particular for a hybrid vehicle.
    [0002] As already known, a hybrid vehicle comprises a powertrain which uses, alone or in combination, as a traction / propulsion drive mode, an internal combustion engine with a variable speed transmission device, and / or a driving / receiving machine, such as a rotary electric machine connected to an electrical source, such as one or more batteries. This combination has the advantage of optimizing the performance of this vehicle, including reducing emissions of pollutants into the atmosphere and reducing fuel consumption.
    [0003] Thus, when it is desired to move the vehicle with a large torque over a wide range of speeds while limiting the generation of exhaust gas and noise, as in an urban site, the use of the electric machine is preferred for drive this vehicle on the move.
    [0004] On the other hand, the engine is used to move this vehicle for uses where high driving power and a long operating autonomy are required. As already known from the French patent application No. 2 955 165 of the applicant, such a powertrain of a motor vehicle comprises a heat engine with a shaft connected to a speed variation transmission device comprising an epicyclic gear with a sun gear. and a ring gear each connected to the shaft of the engine by a controlled-controlled coupling and a fixed part of the unit by a unidirectional automatic coupling, and a planet carrier transmitting the speed variation to the driving axle of the vehicle by the intermediate of a transmission path. In order to increase the speed variation capacity during driving of the vehicle by the electric machine, the applicant associated, with the speed variation transmission device of the aforementioned document, another epicyclic gear train connecting the epicyclic engine gear train to the drive transmission path to the drive axle of this vehicle, as described in the French patent application No. 2,962,697 of the applicant.
    [0005] Thus, the speed transmission device described in the aforementioned applications allows to achieve three speed reports in the forward direction of the vehicle through the engine and two speed reports, in forward or reverse of this vehicle.
    [0006] In a constant effort to improve, the applicant has further perfected this variable speed transmission device by offering the possibility of being able to drive the vehicle by the engine at an additional speed ratio. With this speed ratio, the engine is used on a better operating point while having a torque to the larger wheel. For this purpose, the invention relates to a power train of a hybrid-type motor vehicle comprising a driving / receiving machine, a heat engine, a speed variation device comprising an epicyclic motor train with a sun gear as well as a ring gear each connected to each other. to the motor shaft by a controlled-drive coupling and to a fixed part of the unit by a one-way coupling and a planet carrier, another machine epicyclic gear comprising a sun gear, a ring gear and a planet carrier connected to a device motion transmission device to a drive axle, and a rotational motion transmission path for the connection between said motor shaft and said motion transmission device, characterized in that the motion transmission path comprises a controlled link between motor shaft and at least one of the elements of one of the epicyclic gear trains.
    [0007] The element may be the sun gear or the planet carrier or the ring gear of the planetary gear train. The element can be the planet carrier of the epicyclic motor train.
    [0008] The controlled link may comprise a controlled-control coupling. The controlled link may include a clutch. The controlled link may include unidirectional automatic coupling. The controlled link may comprise a freewheel. The transmission path may comprise two half-shafts interconnected by a unidirectional automatic coupling. One of the half shafts can be connected to the motor shaft and the other of the half shafts can be connected to the controlled drive coupling. One of the half shafts can be connected to the motor shaft and the other of the half shafts can be connected to an element of one of the planetary gear trains. The other of the half shafts can be connected to the planet carrier of the motor epicyclic gear. The transmission path may comprise a toothed wheel connected to the motor shaft by the unidirectional automatic coupling and a gearwheel connected to the ring gear of the machine epicyclic gear. The other features and advantages of the invention will now appear on reading the description which will follow, given solely by way of illustration and not limitation, and to which are appended: FIG. 1 which is a diagram showing a powertrain using a power train with a speed variation transmission device according to the invention; FIG. 2 which schematically illustrates a variant of the powertrain of FIG. 1; FIG. 3 which shows a variant of the powertrain of FIG. 2 and FIG. 4 which is another variant of the powertrain of FIG. 2. In FIG. 1, the powertrain comprises a heat engine 10, in particular an engine. internal combustion engine, with a motor shaft 12, here from the crankshaft of the engine, and a variable speed transmission device 14 to a drive axle 16 which drives the drive wheels 18 of the vehicle. The drive shaft 12 also has a receiving shaft function but for the sake of simplification of the description, this shaft remains called motor shaft so as to distinguish it from other shafts of the transmission device. The power train also includes a prime mover, such as an electric motor 20 with a rotor 22, which can function as an electric drive motor for the vehicle by being connected to a power source, such as batteries (not shown) or as a generator of electrical energy and more particularly as an alternator for charging these batteries.
    [0009] The speed variation device 14 comprises a main epicyclic gear train 24, called the epicyclic heat engine gear train, with two controlled-control couplings 26, 28, here in the form of a friction clutch, and two unidirectional automatic couplings, such as wheels. free 30, 32.
    [0010] More specifically, the motor epicyclic gear train 24 comprises a sun gear 34 fixedly supported by a hollow shaft 36, said sun gear shaft, which cap the shaft 12 of the motor being free to rotate but fixed in translation relative to that -this. The free end 38 of this hollow shaft is supported in a bearing 40 carried by a fixed element 42 of the powertrain through the free wheel 32, called the freewheel, which allows the rotation of the sun gear in one direction .
    [0011] This train also comprises a ring gear 44, placed concentrically with the sun gear, and fixedly connected to a hollow shaft 46, said crown shaft, surrounding the hollow sun gear shaft 36 while being free to rotate but fixed in translation by report to this one. This ring is connected externally to the fixed element 42 of the powertrain of the vehicle by the unidirectional coupling 30, called crown freewheel, which only allows the rotation of the ring in one direction. Of course, the two freewheels 30 and 32 are placed in such a way that the sun gear 34 and the ring gear 44 can only rotate in the same direction and preferably in the same direction as the motor shaft 12. Finally, this epicyclic gear train motor comprises a planet carrier 48 with advantageously three satellites 50, in the form of a gear with external teeth, placed in the same angular interval relative to each other (here at 120 °) and meshing with the crown and the planetary. For this purpose, the sun gear 34, the ring gear 44 and the satellites 50 are situated in the same plane, here in a vertical plane by considering FIG. 1. These satellites are each carried by a horizontal axis 52 while being free to rotate but fixed in translation on it. These satellite axes are connected to a tubular shaft 54, said planet carrier shaft, which surrounds the sun gear shaft 36 by being free to rotate thereon. The free ends of the sun gear shafts and the ring gear each carry a controlled control coupling 26 and 28, preferably a friction clutch each controlled by a lever control. Thus, the clutch 26, called the sun gear clutch, makes it possible to couple the sun gear 34 with the motor shaft 12 while the clutch 28, called the crown clutch, is intended to couple the ring gear 44 to this shaft. engine.
    [0012] As best illustrated in Figure 1, the planet carrier shaft 54 fixedly carries a sun gear 56 of an additional epicyclic train 58, hereinafter referred to as the machine epicyclic train description.
    [0013] This epicyclic machine train 58, which is placed coaxially with the epicyclic motor gear train 24 on the motor shaft 12, comprises a planet carrier 60 with advantageously three satellites 62, in the form of an externally toothed wheel, carried by axles of FIG. satellites 64 and placed in the same angular interval relative to each other (here at 120 °) and meshing with the sun gear 56.
    [0014] These satellites also cooperate in meshing with a ring gear 66 which meshes with a toothed wheel 68 fixedly carried by the rotor 22 of the electric machine 20. Of course, as for the epicyclic heat engine train 24, the sun gear 56, the satellites 62 and the ring gear 66 are located in the same plane, here in a vertical plane by considering FIG. 1. The planet axes 64 are carried by a plate 72 comprising a tubular bearing 74 freely rotating but fixedly in translation. This tubular bearing also carries a gear wheel 76 which cooperates with a toothed wheel 78 connected to the axle 16. This set of two toothed wheels 76 and 78 thus forms a motion transmission device. between the machine epicyclic train 58 and the axle 16.
    [0015] The planet carrier shaft 54 of the epicyclic machine train also carries a controlled-effect double-acting coupling 80 which is fixed in rotation on this shaft but free in translation under the effect of a control means 82. for example, this coupling is a clutch that can cooperate, either with a complementary coupling surface 84 provided on the fixed element 42 of the powertrain (position 1), or with another complementary coupling surface 86 placed on the end of the tubular bearing 74 of the planet carrier 60 (position 2). This clutch also fixedly carries a toothed wheel 88 whose role will be explained in the following description.
    [0016] This clutch thus forms a controlled connection between the motor shaft 12 and at least one of the elements of the machine epicyclic gear train 58, here the planet carrier 60 and / or the sun gear 56. This group also comprises a drive channel. rotational movement transmission 90 for the connection between the motor shaft 12 and the motion transmission device 79 so as to allow the vehicle to be driven by the heat engine according to a fourth additional speed ratio, as will be explained later .
    [0017] This rotational movement transmission path comprises a rotational movement transmission shaft 92 substantially parallel to the motor shaft 12. This shaft advantageously consists of two parts 92a and 92b (or half-shafts) interconnected by a unidirectional coupling 94, here in the form of a freewheel. Each half-shaft 92a, 92b is carried by a bearing 96, respectively 98, from a fixed part 42 of the powertrain. The end of one of two half-shafts carries a cage 100 in which is placed the freewheel while the free end of the other of these half-shafts bears on the inner diameter of this freewheel. This makes it possible to obtain a simultaneous rotation of the two half-shafts only in one direction of rotation. The half-shaft 92a carries at its end directed towards the motor 10 a stationary gear 102 which cooperates with the toothed wheel 88 carried by the clutch 80. The other shaft 92b carries, at its end opposite the cage 100, a wheel stationary gear 104 which meshes with a stationary gear 106 carried by the shaft 12.
    [0018] Thus the motion transmission path 90 comprises the toothed wheel 106 of the motor shaft 12, the two half-shafts 92a and 92b associated with the freewheel 94 and with the toothed wheels 104 and 102, the toothed gear 88 of the dog and the clutch 80. This lane thus comprises a connection between the motor shaft 12 and the tubular bearing of the planet carrier carrying the gearwheel 76 which is controlled by the clutch 80. 3014 773 8 The various vehicle drive configurations by the powertrain will now be described according to the traction / propulsion mode used. For reasons of simplification of the description, only the traction / propulsion configurations by the heat engine or the electric motor are mentioned, the other configurations have already been explained in the applicant's patent applications cited above. With regard to the driving of the vehicle by the electric motor 20, the two clutches 26 and 28 are inactive. In the position 1 of the clutch 80 which cooperates with the coupling surface 84 of the fixed element 42, the sun gear 56 of the train 58 and the planet carrier 48 of the train 24 are immobilized in rotation. As soon as the electric motor 20 is electrically powered, its rotor 22 is rotated. This rotational movement is transmitted to the ring gear 66 of the epicyclic gear train 58, then to the satellites 62 and to the planet carrier 60 and finally to the axle 16 through the motion transmission device 79. In the position 2 of the clutch 80 which cooperates with the coupling surface 86 of the bearing 74, the sun gear 56 of the train 58 and the planet carrier 48 of the train 24 are connected to the planet carrier 60 of the train 58. The rotation of the ring gear 66 is thus transmitted to the planet carrier assembly 60 / planet 56. The rotation of this assembly is retransmitted to the gear wheel 76 which cooperates with the gear wheel 25 axle thereby driving the wheels of the vehicle in rotation. The other configurations will be described now to illustrate the traction / propulsion of the vehicle by the engine 10 at different speeds. In these configurations, the clutch 80 is either in the neutral position for the speed ratios of 1 to 3 or in the position 2 for the speed ratio 4. The clutches 26 and 28 are, for the speed ratio 1 , both inactive, and these clutches are, for gear ratios 2 to 4, either in the active position, or one or the other in the active position. With regard to the gear ratio 1, the clutches 26 and 28 are in the inactive position and the clutch is in position 2. The rotational movement of the shaft 12 of the engine 10 is transmitted to the half-shaft 92b by the gearing. formed by the gears 106 and 104. This rotational movement of this half-shaft is then transferred to the other half-shaft 92a through the freewheel 94 which is then active so as to drive in the same direction of rotation this other half-tree. The rotation of this half-shaft is transmitted to the toothed wheel 88 of the dog 80 by the toothed wheel 102 and the hollow shaft 54. The rotation of the toothed wheel 88 is then transmitted to the planet carrier shaft bearing the planetary 56 of the train 58, then to the planet carrier 60 of this train through the surface 86 which rotates at the same speed. As previously described, we find, from this configuration, the same path of the motion transmission of the planet carrier to the motion transmission device 79 and the axle 16. When the dog is in position 2, the rotation of the toothed wheel 88 is transmitted to the planet carrier shaft carrying the sun gear 56 of the train 58 and then to the planet carrier 60 of this train, which then rotates at the same speed. Likewise, as mentioned above, the motion transmission of the planet carrier / planet gear assembly is tracked towards the motion transmission device 79 and the axle 16.
    [0019] For the active position of the clutch 26 and inactive of the clutch 28 of the speed ratio 2, the rotation of the shaft 12 of the heat engine 10 rotates the sun gear 34. The rotation of the sun gear rotates in turn the planet carrier 48 with its planet carrier shaft 54. The planet carrier shaft rotates the sun gear 56 of the other epicyclic gear train 58 by the shaft 54. This planet gear then drives the planet carrier 60 of this train 58. The planet carrier then drives the axle 16 via the wheels 76 and 78 of the motion transmission device 79, the dog clutch 80 being in position 2. 3014 773 10 For the active position of the clutch 28 and inactive of the clutch 26 (speed ratio 3), the rotation of the shaft 12 of the heat engine 10 rotates the ring 44 which rotates the planet carrier 48. This rotation of the planet carrier is then transmitted to the sun gear 56 of the train picycloïdal 5 Machine 58 by the shaft 54. The sun gear then drives the planet carrier 60 of the train 58 with the transmission of rotational movement to the axle as previously mentioned. In the configuration where the two clutches 26 and 28 are in the active position for the speed ratio 4, the rotation of the shaft 12 of the heat engine 10 rotates the ring 44, the sun gear 34 and consequently the planet carrier 48 of the epicyclic motor train 24. This rotation of the planet carrier is then transmitted to the sun gear 56 of the other epicyclic gear train 58 by the shaft 54. This sun gear in turn drives the planet carrier 60 of this train 58 by 15. via the clutch 80 and the surface 86. The planet carrier then drives the axle 16 via the wheels 76 and 78 of the motion transmission device 79, the clutch 80 being in position 2. Simultaneously, the rotation of the planet carrier shaft 54 is transmitted to the half-shaft 138 by meshing of the toothed wheel 88 of the clutch with the toothed wheel 102 of the half-shaft 92a, but, because of the presence of the freewheel 94, this rotation is not retransmitted to u half-shaft 92b. A speed ratio 1 is thus obtained by the inaction of the clutches 26 and 28, a speed ratio 2 by the action of the clutch 26, a speed ratio 3 25 by the action of the clutch 28 and a speed ratio 4 during the simultaneous action of the clutches 26 and 28. The variant of FIG. 2 differs from FIG. 1 in the parallel arrangement of the two planetary gear trains 24 and 58 as already described in the application of Patent No. 2,962,697 of the applicant as well as by the controlled connection with one of the elements of the machine epicyclic train 58, here the ring gear 66. This group comprises an epicyclic motor train 24 similar to that of FIG. machine epicyclic gear train 58 placed on another shaft. The epicyclic gear train 58 is placed on a fixed shaft 110, substantially parallel to the drive shaft 12, being carried by the fixed element 42 of the group. This epicyclic machine train comprises a sun gear 56, a planet carrier 60 with advantageously three satellites 62 and a crown gear wheel 66. The planet carrier comprises a tubular bearing 74 freely rotating but fixed in translation. 110. This tubular bearing also carries a gear wheel 76 which cooperates with a gear wheel 78 connected to the axle 16. Of course, as for the epicyclic gear train of the heat engine 24, the sun gear 56, the satellites 62 and the crown 64 are located in the same plane, here in a vertical plane by considering Figure 1. This set of two gears 76 and 78 thus forms a motion transmission device 79 between the epicyclic machine train 58 and the 16. The ring gear 66 carried by a crown shaft 112 also comprises a controlled-action double-acting coupling 114 of the dog type, mounted in a rotational manner. by this ring while being movable in axial translation thereon. This clutch is controlled by a command 116 to obtain two meshing positions (1, 2) and a neutral position (N). This clutch is designed to cooperate, either with a fixed coupling surface 118 carried by a fixed element 42 of the powertrain, or with another coupling surface 120 carried by the planet carrier 60. Thus, under the effect of the control 116, the clutch can make a coupling of the ring gear 66 with the fixed element 42 (position 1), with the planet carrier 60 (position 2) or be in neutral position (position N) without being in position. Bonding with either of the two mating surfaces. The sun gear 56 which is carried by a sun gear shaft 118 which comprises a stationary gear 124 which meshes with the toothed wheel 68 carried by the rotor 22 of the motor 20.
    [0020] As best seen in Figure 2, the rotational connection between the two trains is provided by the cooperation of two gears 126 and 128. One 126 of these wheels is carried by the planet carrier 48 of the epicyclic motor train 24 and the other 128 of these wheels is carried by the shaft 112 of the ring gear 66 of the machine epicyclic gear train 58. The motion transmission path 130 comprises a toothed wheel 132 which is free to rotate but is fixed in translation, carried by the motor shaft 12 through a unidirectional automatic coupling 134, here a freewheel, which provides a controlled connection with this wheel, a toothed wheel 136 carried by the crown shaft 112, and the ring 66 bearing the clutch 114. The operation of this variant for the gear ratios 2 to 4 for the traction / propulsion of the vehicle by the engine 10 is similar to that previously described with the clutch 114 in the neutral position or 2 and the clutches 26 and 28 either in the active position or one in the active position according to different speed ratios. During these speed reports, the rotation of the motor shaft 12 is not transmitted to the gear 132 because the freewheel 134 is not rendered operational due to a speed of rotation of the gearwheel 134 This speed of rotation is obtained by the number of teeth of the gears 126, 128, 136 and 132. For the gear ratio 1, the two clutches are inactive and the dog clutch 114 is in position N or 2.
    [0021] As soon as the motor shaft 12 has reached a sufficient rotational speed, the freewheel is active by driving the toothed wheel 132 in rotation. This rotation is then transmitted to the toothed wheel 130 and then to the crown 66. is in the neutral position N, the rotation of the ring gear 66 is transmitted to the planet carrier 60 of this train and to the sun gear 56 via the satellites 62. The rotation of this planet carrier 60 is then transmitted to the transmission device movement 79 which then drives the axle 16 via the wheels 76 and 78.
    [0022] When the dog is in position 2, the ring 66 and the planet carrier 60 are locked together and then rotate at the same speed. The rotation of this planet carrier / crown assembly makes it possible to drive the axle 16 in rotation through the motion transmission device 79 with the wheels 76 and 78. The variant of FIG. 3 differs from that of FIG. , by the configuration of the transmission path that includes the controlled link.
    [0023] As for FIG. 2, the rotational connection of FIG. 3 between the two trains 24 and 58 is provided by the cooperation of two toothed wheels 126 and 128. One of these wheels is carried by the planet carrier 48 of the epicyclic motor train 24 and the other 128 of these wheels is carried by the shaft 112 of the ring gear 66 of the machine epicyclic train 58. The motion transmission path 138 comprises the toothed wheel 132 carried by the motor shaft 12 through the free wheel 134, which provides a controlled connection between the shaft and the wheel. This transmission path is different from that of FIG. 2, in that the toothed wheel 132 meshes with a toothed wheel 140 carried by an intermediate shaft 142 substantially parallel to the motor shaft 12. This shaft, fixed in translation but free in rotation on fixed bearings 144 of the element 42, also carries another gear 146 which meshes with a toothed wheel 148 carried by the planet carrier 48 of the train 24.
    [0024] Thus the motion transmission path comprises the toothed wheel 132, the freewheel 134, which provides the controlled connection between the motor shaft 12 and this wheel, the toothed wheels 140 and 146 carried by the intermediate shaft 142, the wheel 148 carried by the planet carrier 48, the gear wheel 126 also carried by the planet carrier 48, the wheel 128 carried by the crown shaft 112, and the ring gear 66 bearing the clutch 114. The operation of this variant for the traction / propulsion of the vehicle by the engine 10 or the electric motor 20 is similar to that described above in connection with Figure 2.
    [0025] The variant of FIG. 4 takes part of the configuration of FIG. 1 and part of the configuration of FIG.
    [0026] Thus, the group comprises an epicyclic motor train 24 placed on a motor shaft 12 and an epicyclic machine train 58 placed on another shaft 110, similar to those of Figure 2 and a motion transmission device 79 between the epicyclic machine train 58 and the axle 16 and which is formed by the gear wheels 76 and 78.
    [0027] In addition, as for the variant of FIG. 3, the rotational connection between the two trains is ensured by the cooperation of the two gears 126 and 128. This group further comprises a rotational movement transmission path 150 for the link between the motor shaft 12 and the motion transmission device 79 so as to allow the vehicle to be driven by the heat engine at an additional speed ratio (ratio 1). This rotational movement transmission path, which is close to that of FIG. 1, comprises a rotational movement drive shaft 92 substantially parallel to the motor shaft 12. This shaft advantageously consists of two parts 92a and 92b (or half-shafts) interconnected by a free wheel 94, each half-shaft 92a, 92b is carried by a fixed bearing 96, respectively 98, from a fixed portion 42 of the powertrain. The end of one of two half-shafts carries a cage 100 in which is placed the freewheel 94 while the free end of the other of these half-shafts bears on the inner diameter of this freewheel. The freewheel 94 thus makes it possible to achieve a controlled connection between the two half-shafts. The half-shaft 92a carries at its end directed towards the motor 10 a stationary gear wheel 102 which cooperates with the gear wheel 148 carried by the planet carrier 48 of the motor epicyclic gear train 24. The other half shaft 92b carries, at its opposite end to the cage 100, a stationary gear 104 which meshes with a stationary gear 106 carried by the shaft 12.
    [0028] Thus the motion transmission path 150 comprises the toothed wheel 106 of the motor shaft 12, the two half-shafts 92a and 92b associated with the free wheel 94 which makes it possible to achieve a controlled connection, the toothed wheels 104 and 102, the wheel 148 carried by the planet carrier 48, the toothed wheel 126 also carried by the planet carrier 48, the wheel 128 carried by the crown shaft 112, and the ring gear 66 bearing the clutch 114. The operation of this variant for traction / propulsion of the vehicle by the engine 10 or the electric motor 20 is similar to that described above in connection with Figure 2 with the feature that the free wheel 94 provides the controlled link function as described in Figure 2 .
