Abstract

The invention relates to a hybrid vehicle drive train which can be operated both as a parallel hybrid and as a series hybrid. In this case, there are two electrical machines which can be coupled for operation as a parallel hybrid by means of a coupling. In order to build the space for the two electrical machines and the clutch so small that they fit into the space, which is normally claimed by a hydrodynamic torque converter, a space-saving structural design is proposed according to claim 2. According to claim 1, a structural design of a passage shaft bearing is proposed which particularly well supports the forces - in particular the gyroscopic moments - of the electric machine close to the drive. Furthermore, a hybrid vehicle drive train with an electric and a mechanical oil pump drive is proposed according to claim 11.

Description

  • The invention relates to a hybrid vehicle drive train according to the generic term of claim 1, the preamble of claim 2 further relates the invention a hybrid vehicle powertrain according to the one-piece Claim 11.
  • The not pre-published DE 101 60 666.1-12 already includes a hybrid vehicle powertrain in which between two internal combustion engine and a gearbox two rotors of electric machines axially adjacent and coaxial with each other, wherein the two rotors are separable from each other by means of a clutch.
  • Object of the invention according to claim 1 is one, even among the highest Loads fail-safe powertrain to create.
  • An advantage of claim 1 is that the gyroscopic moments closer to the gearbox electric machine are supported by bearings of a through shaft. Such gyroscopic moments arise when the very heavy and thus mass sluggish Rotor of the electric machine turns fast and the motor vehicle rotates at high angular velocity about the vertical axis, as with slippery roads can happen. Furthermore, these high gyroscopic moments during ramming movements of the engine-gearbox while driving over from bumps occur. This creates the said centrifugal forces as high reaction forces, the invention safe be supported. The bearings of the through shaft are on the one hand in a recess the crankshaft of the internal combustion engine and on the other at one housing part arranged, which are designed in particular as a bearing neck can. In this case, the arranged within the housing part bearing especially large dimensions and radially within the closer to the transmission electrical Machine be arranged so that in addition to the high gyroscopic moments the dead weight and the technical imbalance of the rotor of electric machine can be easily absorbed by this camp.
  • In a particularly advantageous Embodiment of the invention, the bearing neck, in its recess the aforementioned bearing is received, also a release piston a central release take up. With this then the clutch is disengaged and. How closer below explained, can the housing part, which forms the bearing neck, also a mechanical and / or electrical driven oil pump take up.
  • The structural design in particular according to claim 10 allows it advantageously the hybrid vehicle powertrain as modular Alternative to a hydrodynamic torque converter of an automatic transmission manufacture. This may result in different types of vehicles - i. such a with converter automatic transmission and those with hybrid drive - the same shell be used. Only the battery for the hybrid vehicle powertrain it applies in a special way structurally. Otherwise, the usual Components of the automatic transmission are used. There are cost advantages associated.
  • The task of claim 2 is one possible to create compact hybrid vehicle powertrain.
  • The clutch is actuated by a Bridge through which the rotor of the gear closer to the electric Machine carries. Of the Bridge can in a particularly advantageous manner as a bridge disc be configured as claimed in claim 16.
  • The hybrid vehicle powertrain generally has a fuel economy advantage.
  • The hybrid vehicle powertrain can be used as serial at particularly slow speeds Hybrid operated. The coupling is open and the first - or geared - electrical Machine is operated as a generator whose voltage is the engine operated second - or close to the engine - electric Machine drives. As a buffer while the battery is interposed. Since slow speeds are accomplished, the clutch can be particularly advantageous designed as a dry rub clutch What goes along with cost advantages and efficiency advantages, since no special lubricant circuit is necessary. Normally will the clutch engaged with equal speed of the two coupling halves, so that no, pronounced Slip phase with appropriate friction work occurs. Ideally will ever does no friction work.
  • Object of the invention according to claim 11 is a cost-effective yet to provide fail-safe hybrid vehicle powertrain.
  • In the hybrid vehicle drive train two oil pumps for oil pressure supply of the automatic transmission and - if necessary in addition - the large bearing can be present in a particularly advantageous manner. In this case, the one oil pump can be configured as a mechanical oil pump, whereas the other oil pump is electrically operated. The mechanically operated oil pump may preferably be a crescent pump driven by the transmission input shaft, which is also accommodated in the housing part, which forms the bearing neck for receiving large bearings and the release piston. When using a mechanical and an electric oil pump, both can have a setback valve to be connected to a pressure line of the automatic transmission.
  • Alternatively to a mechanical one and a separate electric oil pump may also provide a single oil pump be, which is both mechanically and electrically driven. Such an oil pump could For example, look like that the transmission input shaft and the Electric motor together over a superposition gearbox or freewheels the oil pump drive, wherein the electric motor - if de-energized - against reverse rotation secured by a freewheel. But even when using a single oil pump is for the case that this is operated only electrically, the worst case - i. the maximum possible Load case - cover. This worst case occurs, for example, when the motor vehicle is transverse to the curb, the clutch for serial operation of both electric machines is opened as a starting element and thus a high torque from the one driven electric Machine is applied even though the vehicle is stationary. This tall Torque is directed into the automatic transmission. If then the oil in the transmission is fluid due to a high temperature and thus causes high leakage, the transmission oil working pressure in Height of 25bar only be applied when the electrically operated oil pump a Electric motor with a high power of over 1kW.
  • In a particularly inexpensive, small and light embodiment of the invention is a on the demanding normal case dimensioned - i. relatively small - electric motor used, which also has the advantage that the electric motor cooling is lower can be dimensioned. If at such a small size Electric motor of the aforementioned worst gases occurs, the falls Transmission fluid operating pressure on under 25bar depending on height the transmission oil working pressure the Lammellenkupplungen / brakes of the automatic transmission slip fen. Consequently, the transmission input shaft of the as an electric motor driven electric machine in rotation, so that the additional mechanical Drive supplies the additional oil flow, around the transmission oil working pressure on over 25bar increase. In the case of a single oil pump, which is both mechanically and electrically driven, is the total flow rate the oil pump elevated. In the case of a mechanical and a separate from this electric oil pump both volume flows together the sufficient total flow to the Lammellenkupplungen / brakes of the automatic transmission.
  • In a particularly advantageous Design, the oil pressure specifically lowered on at least one multi-plate clutch in the transmission be so minor slippage occurs so that when the vehicle is stationary, the electric motor can turn to overload individual windings of the second electric machine to prevent.
  • In a particularly advantageous Design of the electric motor for the oil pump, which on the demanding Normal case - that is, relatively small - sized is, a special control device is provided. This Control device controls or regulates inter alia. the torque the electric machine close to the transmission. It prevents the control device that in the aforementioned slippage the Overhead clutches / brakes overloaded become. It will be for The Lammellenkupplungen / brakes Lammellen used, although can not tolerate long-term slippage, but short-term Slack of, for example, 1 second as often tolerated. The said Control device monitored while the slippage duration of the Lammellenkupplungen / brakes of the automatic transmission, whereby a brief slippage is allowed. Becomes a limit the slip time exceeded, Thus, the control device reduces the torque of the second electrical Machine, so that this lower torque in the transmission input shaft initiates. The torque is reduced so far until the Lammellenkupplung / brake no longer slips or alternatively until the speed difference the slipping Lammellenkupplung / brake is so low that no thermal damage the lamellae enters. A possibility for determining the speed difference at the Lammellenkupplung / brake is the comparison the transmission input shaft speed with the transmission output shaft speed, whereby the currently engaged gear is taken into account. Instead of Transmission output shaft speed can also be the speed measured at the drive wheels be, with the gear ratio of the usual considering the existing differential becomes. Further, in the calculation, the transmission output shaft speed Based on the speed at the drive wheels taken into account that the two or four-wheel drive four drive wheels different speeds respectively. The differential is in the case of a Vorderachsantriebes around a front differential and in the case of a Hinterachsantriebes around a rear axle differential. To the torque of the electric To reduce the machine, the control device can have an inverter unit or a power converter unit close to the transmission be connected electrical machine. The inverter unit influences this or the power converter unit, the torque of the said electrical Machine by influencing the amplitude / phase / frequency of the phase currents. Voltage source of the inverter unit is on the one hand the Combustion engine related electric machine, which as Generator is operated. Furthermore, as a voltage source or as Buffer a battery or alternatively a supercapacitor provided.
  • In the previously described worst case on the curb is so high torque at the Gearbox related electric machine that the vehicle wheels must turn in any case. Shortly thereafter, there is such a high driving speed that the total output of the oil pumps is sufficient to conduct a sufficient torque through the Lichellenkupplungen / brakes of the automatic transmission.
  • Should be at the detailed Use of a relatively small-sized electric oil pump with an additional mechanical drive or an additional mechanical oil pump nevertheless under load a too long slip time in the transmission occur, there There are two Abregelmöglichkeiten. For one, the vorgenante torque reduction of the transmission be performed nearby electric machine. On the other hand, in the Automatic transmission through its transmission control upshifts be prevented. As a result, the transmission input shaft remains on a relatively high speed level, so that the capacity the mechanical pump remains at a relatively high level.

  • 1 a schematic representation of a hybrid vehicle powertrain, which is operable by means of two electric machines and a clutch both as a serial, and as a parallel hybrid, and
  • 2 a detail of the hybrid vehicle powertrain which in the range of the two electric machines and the clutch off 1 lies.
  • According to 1 has a hybrid vehicle powertrain 10 via an internal combustion engine 11 , which has a crankshaft 12 with a motor-side coupling part 40 one, with the help of one in 2 closer illustrated clutch actuator actuated, automated clutch 13 connected is. Coaxial to the crankshaft 12 is a first electric machine 41 arranged, which can be operated both as a motor and as a generator. A drivable rotor 42 the first electric machine 41 is non-rotatable with the crankshaft 12 connected so that the first electric machine 41 a torque in the crankshaft 12 can initiate and from the crankshaft 12 can be driven.
  • Between the rotor 42 the first electric machine 41 the motor-side coupling part 40 is a torsion damper 46 arranged, which Drehzahluniformity of the internal combustion engine compensates, so that the following in the power flow region of the hybrid vehicle drive train 10 is relieved of these.
  • The coupling 13 also has a transmission-side coupling part 43 , which with a two-part transmission input shaft 14 a gearbox 15 rotatably connected. The gear 15 is designed as a planetary automatic transmission with switching stages of six forward gears and one reverse gear, in which the gear changes by means not shown multi-plate clutches / brakes are feasible. Coaxial to the transmission input shaft 14 is a second electric machine 44 arranged, which can be operated both as a motor and as a generator. A rotor 45 the electric machine 44 is non-rotatable with the split transmission input shaft 14 connected so that the electric machine 44 a torque in the transmission input shaft 14 can initiate and from the transmission input shaft 14 can be driven. The two electric machines 41 . 44 are designed as three-phase machines.
  • The crankshaft 12 and the transmission input shaft 14 are by means of the motor-side coupling part 40 and the transmission-side coupling part 43 can be coupled and decoupled. The coupling 13 is designed as a dry rub clutch.
  • That of the transmission 15 converted torque and the speed are transmitted via an unillustrated output shaft of the transmission 15 by means of a drive shaft 16 to a axle drive 17 transmitted, which in a conventional manner, the torque in equal proportions over two output shafts 18 . 19 to driven vehicle wheels 20 . 21 transfers.
  • In normal driving, the Drive the motor vehicle with it
    • - the internal combustion engine 11 alone,
    • - the internal combustion engine 11 in combination with the electric machine 41 .
    • - the internal combustion engine 11 in combination with the electrical machines 41 and 44 .
    • - by the electric machine 44 done alone.
  • In addition, the internal combustion engine 11 by means of the electric machine 41 to be started. This is done in an advantageous manner with the clutch open 13 , In special cases, the other electric machine 44 help with engine start.
  • At low speeds, the drive is made by the electric machine 44 , This is advantageous because with the clutch closed 13 otherwise a speed of the internal combustion engine 11 would be too low, so that the clutch 13 should be operated with slippage. This could cause overheating of the clutch designed as a dry rub clutch 13 occur. The internal combustion engine 11 is only at higher speeds by means of the clutch 13 switched on after using the electric machine 41 was started. In this case, then the clutch 13 completely closed, so that no slippage occurs.
  • It is a control device 200 intended. These are recorded as parameters, among others
    • - The speed of a transmission input shaft 14 based on a first speed sensor 202 .
    • - The speed of the transmission output shaft 16 using a second speed sensor 201 and
    • - currently in the transmission 15 engaged gear on the basis of the gearbox control unit 203 ,
  • By means of the control device 200 is via an inverter or a power unit 204 including the torque of the second electric machine 44 adjustable when operated as a motor. The power supply of the second electric machine via a battery and operated as a generator first electric machine 41 ,
  • It is a mechanical oil pump 205 provided, which of the transmission input shaft 14 is driven. Further, an electric oil pump 206 which is provided by an electric motor 207 is driven. The volume flow of the two oil pumps 205 . 206 is brought together via lines which supply the compressed air for the multi - plate clutches and brakes in the transmission 15 are guided. Here is each of the two oil pumps 205 . 206 a check valve 208 . 209 assigned, which prevents the direct pressurization of an oil pump by the other.
  • It is dimensioned to the demanding normal case - ie relatively small - electric motor 207 used, which also has the advantage that the electric motor cooling can be made smaller. In such a small-sized electric motor, the following case may occur:
  • The motor vehicle stands at the curb and the driver tries to maneuver the curb while maneuvering. The coupling 13 is open, allowing for shunting the first electric machine 41 as a generator and the second electrical machine 44 is operated as a motor. Thus, to climb the curb, high torque must be applied to the first electric machine 44 be applied even though the vehicle is stationary. Then, when the oil in the transmission becomes thin due to a high temperature and thus causes high leakage, the transmission oil working pressure of 25 bar can not be solely from the oil pump 205 or the relatively weak electric motor 207 be applied.
  • As a result, the transmission oil working pressure drops below 25bar and, depending on the transmission oil working pressure level, the disc clutch / brakes of the transmission 15 slip. As a result, the transmission input shaft becomes 14 from the powered electric motor driven by the engine 44 set in rotation so that the additional mechanical drive of the oil pump 205 provides the additional oil flow to increase the transmission oil working pressure to over 25bar. The volume flows of the two oil pumps 205 . 206 then jointly provide the Lammellenkupplungen / brakes of the transmission 15 with oil.
  • The control device 200 controls or regulates, inter alia, the torque of the transmission 15 related electric machine 44 , The control device prevents this 200 in that in the aforementioned slippage the disk clutches / brakes are overloaded. In this case, Lammellen are used for the Lammellenkupplungen / brakes, which do not tolerate long-term slippage, however, tolerate indefinitely slipping of, for example, 1 second as often. The said control device 200 monitors the duration of slippage of the Lammellenkupplungen / brakes of the transmission 15 , allowing a brief slippage. If a limit value of the slip time is exceeded, the control device reduces 200 the torque of the electric machine 44 so that these have a lower torque in the transmission input shaft 14 initiates. The torque is reduced so far until the plate clutch / brake no longer slips or alternatively until the speed difference at the slipping Lammellenkupplung / brake is so low that no thermal damage to the slats occurs. The torque is reduced only so far that the vehicle can still start. The slip or the difference in rotational speed on the disks of the Lammellenkupplung / brake is from a comparison of the speed of the transmission input shaft 14 at the speed of the transmission output shaft 16 which is currently in gear 15 inlaid gear is taken into account. To the torque of the electric machine 44 reduce, controls the control device 200 these via the inverter unit 204 , The inverter unit influences this 204 the torque of said electric machine 44 by influencing the amplitude / phase / frequency of the phase currents. Voltage source of the inverter unit 204 is next to the first electric machine operated as a generator 41 a battery which acts as a buffer at the same time.
  • To climb the curb is such a high torque on the electric machine 44 on that the vehicle wheels 20 . 21 have to turn in any case. Shortly thereafter, there is such a high driving speed that the sum flow rate of the two oil pumps 205 . 206 sufficient to a sufficient torque through the Lammellenkupplungen / brakes of the transmission 15 to lead.
  • As a safety feature is in gear 15 provided that by its transmission control 203 Upshifts are prevented. As a result, the transmission input shaft remains 14 at a relatively high speed level, so that also the capacity of the mechanical oil pump 205 remains at a relatively high level.
