Definitions
- the present invention relates to the field of transmissions for motor vehicles with hybrid propulsion comprising, on the one hand, a driving heat engine and, on the other hand, an electric machine.
- the invention relates to hybrid transmissions comprising two concentric primary shafts each carrying at least one pinion gear on a secondary shaft connected to the wheels of the vehicle.
- hybrid transmissions The interest of hybrid transmissions is to provide two sources of energy, thermal and electrical, to the kinematic drive train of the vehicle.
- the torque contributions of these two energies can be accumulated in a so-called “hybrid” mo or can be used separately, in a so-called “pure thermal” mode where the electric machine does not provide torque to the traction chain, either in a so-called “pure electric” mode, where the engine does not provide torque to the power train.
- Hybrid transmissions are used to drive the engine off or on the road using the electric machine as a starter. Hybrid transmissions can also charge the vehicle batteries by the electric machine running as a generator.
- Document FR 2 973 299 discloses a transmission for a motor vehicle with hybrid propulsion, in which the primary line comprises a hollow primary shaft connected to the electric machine and a solid primary shaft connected directly to the flywheel of the engine. .
- the solid primary shaft carries at the same time an idler gear meshing with a fixed gear of the secondary shaft. to form a first gear down and two idle gears forming two further gear downs with two fixed gears of the secondary shaft.
- the transmission comprises a first coupling means for producing three different positions in which: the heat engine is decoupled from the kinematic chain connecting the electric machine to the wheels, the heat engine drives the wheels with or without the addition of the electric machine, and the heat engine and the electric machine are coupled to add their respective torques.
- Such a transmission makes it possible to have at least two distinct ratios in electric and hybrid mode and a higher ratio in thermal mode dedicated to fast rolling, such as for example at 130km / h.
- the electric machine can be used as the only source of motive power on a short gear, suitable for city driving and an intermediate gear, suitable for driving on the road beyond an intermediate speed threshold, for example the 100km / h.
- a long ratio is used where the heat engine alone is coupled to the wheels. In this case, the electric machine is used as an energy generator to recharge the battery.
- the objective of the invention is therefore to overcome these drawbacks and to optimize the modes of the transmission in order to have mo hybrids under torque.
- the object of the invention is therefore to provide a transmission for a hybrid propulsion vehicle in which the speed jump between two reduction ratios in electric mo is reduced and thus, to improve driving comfort in hybrid mode.
- This reduction allows a greater flexibility of use of the two reports usable by electric machine which can thus have a range of recovery, concretely the regime of change of ratio between these two ratios can be selected without constraint in the recovery range.

- Said transmission includes a first coupling system between the solid primary shaft and one of its two idle gears and a second coupling system between the two secondary shafts or between the solid secondary shaft and its idler gear.
- the gear of second gear ratio transmits all of the combined torque from the electric machine and the engine, whereas in the case of the present invention, the two gears never transmit the combined torque of the electric machine and the heat engine.
- the present invention therefore makes it possible to reduce the dimensions and in particular the widths of the two gears making it possible to differentiate the speeds of the heat engine and the electric machine without impacting the total length of the transmission.
- the thermal mode alone on the motorway is thus replaced by a hybrid mode.
- the transmission has at least a first electrical mode, in which the first coupling system is open, while the second coupling system is closed so as to isolate the idler gear of the short ratio with the solid secondary shaft. .

- the transmission has at least one charging mode of the battery in which the first coupling system is closed so as to couple the second idle gear and the solid primary shaft, and the second coupling system is open.
- the heat engine comprises an integrated starter system of low or high voltage alternator / starter type, or an ISG type starter on the flywheel.

- the couples of the heat engine 2 and the electric machine 3 s' add up in a long ratio, in a mode "Th4 / E3" said "highway hybrid".
- This transmission mode makes it possible to establish two independent ratios on the one hand of a third gear ratio for the electric machine 3 and on the other hand a fourth gear ratio for the heat engine 2. are established directly without any loss of efficiency.
- the recharging mode is obtained by locking the second idler 7b and the solid primary shaft 7 by the first coupling means 9 and thus by locking the two shafts together. primary 7, 8 through the hollow secondary shaft 1 1, without lowering of movement on the secondary line 5.
- the starter system can be, for example, a conventional starter, a low-voltage or high-voltage starter-starter, or an ISG type starter ("Integrated Start Generator" in English terms) on the flywheel;
- This transition is under torque, because it is pushed by the engine on the second report. It is hardly felt by the users, because it is carried out without variation of engine speed.
- Th4 / E3 hybrid highway mode illustrated in FIG. 8, as follows:
- the fourth reduction ratio is determined to ensure the best compromise on the engine 2 alone to minimize energy consumption at high speed, for example at 130km / h and to ensure sufficient capacity to cross the slopes on the motorway.
- the third reduction ratio is determined to ensure the best compromise on the electric machine 3 alone.
- a simplified mode can be used to manage critical situations with a low level, so as to reduce the risks of immobilization by complete unloading. batteries (not shown).
- the electric machine 2 which charges the battery , we join the low-speed electric mode (from 1 to about 40km / h), illustrated in Figure 2, leaving the engine 2 to turn on its idle independently of the traction:
- This transition is under torque because it is pushed by the electric machine 3 on the first report, which facilitates the steering of the thermal engine 2 which meshes on the secondary line 5 by a sequence of three successive reports, namely the fourth report, the third report and the first report.
- FIG. 10 differs from the embodiment illustrated in FIG. 1 by the position of the various elements constituting the transmission, the operation of such a transmission being identical to the operation of the transmission illustrated in Figure 1.
- the transmission 1 is intended to be integrated in a hybrid-propulsion motor vehicle (not shown) comprising, on the one hand, a driving heat engine 2 and, on the other hand, an electric machine 3
- the transmission 1 comprises a primary line 4 and a secondary line 5.
- the electrical machine 5 is disposed at one end of the primary line 4 and the heat engine 2 is disposed at a second end of the primary line 4 , opposite to the first end.
- the electric machine 5 is located at the front of the gearbox, so as to mask the length of the pinion gear 10c of the differential 6.
- this new architecture is well suited to large vehicles.
- the primary line 4 comprises a solid primary shaft 7, of axis Xi, connected directly via a filtration system (not shown), such as for example a damping hub, double flywheel or any other suitable means, the flywheel of a heat engine 2 and a hollow primary shaft 8, coaxial with the solid primary shaft 7, and connected to the rotor of the electric machine 3.
- the solid primary shaft 7 has free rotation two idle gears 7a, 7b can be selectively connected to the solid primary shaft 7 by a first coupling system 9, such as for example a clutch, a synchronizer, or other type of coupler progressive or not.
- the hollow primary shaft 8 carries two fixed gears 8a, 8b.
- the secondary line 5 comprises a solid secondary shaft 10, of axis X 2 , and a hollow secondary shaft 11, coaxial with the solid secondary shaft 11.
- the axis X 2 of the secondary trees is parallel to the axis Xi of the primary trees.
- the solid secondary shaft 10 carries a free spinning pinion 10a that can be selectively connected to the solid secondary shaft 10 by a second coupling system 12, such as for example a clutch, a synchronizer, or other type of progressive coupler or no, a fixed gear 10b and a down gear 10c to the differential 6 connected to the wheels (not shown) of the vehicle.
- a second coupling system 12 such as for example a clutch, a synchronizer, or other type of progressive coupler or no
- a fixed gear 10b and a down gear 10c to the differential 6 connected to the wheels (not shown) of the vehicle.
- the hollow secondary shaft 11 carries two fixed pinions 11a, 11b and can be connected to the solid secondary shaft 10 by the second coupling system 12.
- the first idler gear 7a of the solid primary shaft 7 meshes with the fixed gear 10b of the solid secondary shaft 10 to form a first gear down, corresponding to the intermediate ratio, or second reduction ratio of the transmission 1.
- the second idler 7b of the solid primary shaft 7 meshes with the first fixed gear 11a of the hollow secondary shaft 11 to form a second gear down, corresponding to the fourth reduction ratio of the transmission 1.
- the two fixed gears 8a, 8b of the hollow primary shaft 8 mesh respectively with the second fixed gear 11b of the hollow secondary shaft 11 to form a gear descent corresponding to the third gear ratio called “long ratio" of the transmission 1, and with the idle gear 10a of the solid secondary shaft 10 to form a descent gear corresponding to the first reduction ratio called “short ratio" of the transmission 1.
- the first coupling means 9 makes it possible to couple the solid primary shaft 7 with one of its two idle gears 7a, 7b.
- the second coupling means 12 makes it possible to couple the two secondary shafts 1 0, 1 1 between them, or the solid secondary shaft 10 with its idle gear 10a.
- the transmission has many possibilities of use adapted to various driving modes.
- the transmission allows a relaxation of the change between two reports in electric mode and thus, the improvement of the driving comfort in hybrid mode.
- the proposed transmission does not have a "pure thermal mode" on the highway. Indeed, the pure motorway thermal mo existing in known transmissions is thus replaced by a hybrid mode on the third and fourth reports, to reduce the energy consumption on the highway.
