Definitions

  • the invention relates to a transmission for a motor vehicle, and a drive train for a motor vehicle with such a transmission.
  • a transmission referred to here in particular a multi-speed transmission in which a plurality of gears, so fixed ratios between two shafts of the transmission, are preferably automatically switched by switching elements.
  • the switching elements are, for example, clutches or brakes here.
  • Such transmissions are mainly used in motor vehicles to adapt the speed and torque output characteristics of the drive unit to the driving resistance of the vehicle in a suitable manner.
  • the patent application DE 10 2014 204 009 A1 describes a multi-speed planetary gear system as a component of a motor vehicle drive train, which has a power input, a power output, two planetary gear stages, two clutch devices, two brake devices and an electric motor.
  • the planetary gear system allows the formation of four forward gears.
  • Fig. 7b of this patent application an embodiment is shown, in which the power input and the electric motor are arranged at axially opposite axial ends of the planetary gear system.
  • the power output is arranged axially between the two planetary gear stages.
  • One of the two brake devices is arranged radially inside the electric motor.
  • the planetary gear system described above has an axially long construction. Because the elements clutch devices, power output, planetary gear stages and electric motor are arranged one behind the other in the axial direction. In a motor vehicle with aligned transversely to the direction of travel of the motor vehicle hybrid powertrain is particularly important to pay attention to an axially short design, since the composite drive unit, gearbox and electric motor is to be arranged between the longitudinal members of the motor vehicle. If a higher number of gears is required, the space requirement is exacerbated by the required additional components.
  • the transmission has a drive shaft, an output shaft, an interface to a transmission-external drive unit, a plurality of switching elements, a plurality of planetary gear sets and an electric machine.
  • the electric machine comprises a rotationally fixed stator and a rotatable rotor, and is disposed at that axial end of the transmission, which faces the interface to the transmission-external drive unit.
  • the rotor is connected to the drive shaft in such a way that a power transmission between the drive shaft and the rotor is possible.
  • Such a connection can be formed for example by a direct connection between the rotor and drive shaft.
  • a transmission gear may be present, such as a planetary gear or a spur gear.
  • the rotor may be constantly connected in the same way to at least one element of the planetary gear sets.
  • the output shaft is permanently connected to an element of at least one of the planetary gear sets, and has a toothing on an interface. This toothing meshes with a toothing of a shaft parallel to the axis of rotation to the output shaft.
  • the axle drive of a motor vehicle drive train may be arranged, which may also be part of the transmission.
  • a further axis-parallel shaft can be interposed between the axle drive and the output shaft in order to better bridge the center distance between the axle drive and the output shaft.
  • the switching elements comprise at least one first switching element acting as a brake.
  • the brake is used for switchable rotationally fixed fixing of a transmission element.
  • This first switching element is arranged in the axial direction next to the electric machine, ie next to the stator or next to the rotor. In other words, the first switching element is arranged at a diameter which is at least as large as the diameter of the stator or the rotor. Furthermore, the first switching element is arranged axially between the interface of the output shaft and the electric machine. In other words, a plane of the output shaft toothing is arranged axially adjacent to a plane of the first switching element.
  • One of the planetary gear sets is disposed radially inward of the first shift element, and another of the planetary gear sets is disposed radially inward of the electric machine. Because the arrangement of the first switching element in addition to the electric machine creates a substantially cylindrical cavity radially within these components, which can be used to arrange two planetary gear sets of the transmission. This cavity may extend from the interface of the transmission-external drive unit opposite axial end of the transmission to the interface of the output shaft. By this configuration, the axial length of the transmission can be reduced.
  • that planetary gear set disposed radially inside the electric machine serves to provide a switchable, fixed gear ratio between the drive shaft and at least one member of that planetary gear set disposed radially inside the first shift element.
  • the interface of the output shaft is arranged axially between the interface to the transmission-external drive unit and the first switching element.
  • the plane of the output shaft gearing is arranged axially between the plane of the first switching element and the drive unit interface.
  • the interface of the output shaft is thus close to the drive unit interface arranged.
  • the switching elements comprise a switching element designed as a coupling, which is arranged radially inside the electric machine.
  • a switching element designed as a coupling is particularly advantageous when an operative connection between the rotor and another transmission element is effected by closing this coupling.
  • Radial within the electric machine can also be arranged another, acting as a clutch switching element.
  • the two clutches radially inside the electric machine can be arranged directly next to each other.
  • the switching elements comprise a further clutch, which is arranged axially between the drive source interface and the output shaft interface. This is particularly advantageous for a non-positive switching element, since a large effective diameter is available in this section.
  • the switching elements comprise a positive switching element, which is formed radially within the output shaft bearing.
  • Form-fitting switching elements are preferably to be arranged on a small effective diameter in order to keep the construction cost of the positive connection low. By such an arrangement, or training even the space can be used radially within the output shaft bearing. As a result, a particularly efficient use of the transmission installation space is possible.
  • the transmission has a planet tenradsatzsystem with a total of four shafts, which are referred to as first shaft, second shaft, third shaft and fourth shaft. These four waves are characterized in that their speeds in the order named increase, decrease or be linear. In other words, the rotational speed of the first shaft is less than or equal to the rotational speed of the second shaft.
  • the speed of the second shaft is again less than or equal to the speed of the third shaft.
  • the speed of the third shaft is less than or equal to the speed of the fourth shaft.
  • This order is also reversible, so that the fourth shaft has the lowest speed, while the first shaft assumes a speed greater than or equal to the speed of the first shaft.
  • the speed of one or more of the four waves can also assume negative values, or even the value zero.
  • the speed order is therefore always to refer to the signed value of the speeds, and not on the amount.
  • Such a planetary gear set is formed by two-time coupling of two individual planetary gear sets. Examples include the so-called Ravigneaux wheelset or the Simpson wheelset.
  • the transmission has at least one additional planetary gearset.
  • the speed order in the first shaft can be fixed in rotation by closing the first switching element.
  • the speed second shaft is also fixed in rotation, and beyond connectable to the drive shaft.
  • the speed order third shaft is connected to the output shaft.
  • the speed order fourth shaft is connectable to the drive shaft.

  • a plus gear set differs from the negative planetary gear set just described in that the plus gear set has inner and outer planet gears rotatably supported on the land. The toothing of the inner planet gears meshes on the one hand with the teeth of the sun gear and on the other hand with the teeth of the outer planetary gears.
  • Each individual planetary gear set has a first element, a second element and a third element.
  • the first element is always formed by the sun gear of the respective single planetary gear set.
  • the second element is formed by the web of the respective single planetary gear set, and the third element by the ring gear of the respective single planetary gear set.

  • the first element of the third single planetary gear set can be fixed in rotation by closing the first switching element.
  • the first element of the second planetary gear set is permanently connected to the drive shaft.
  • Such a structure is known for example from the published patent application DE 199 12 480 A1, and is suitable for the formation of six forward gears and one reverse gear. Even such a compact construction is well suited for the arrangement in the cavity radially inside the first switching element and the electric machine.
  • the transmission comprises a separating clutch, which is arranged axially between the interface to the transmission-external drive unit and the interface of the output shaft. Due to the separating clutch, the drive shaft can be connected to a connecting shaft. The connecting shaft is used for connection to the gearbox-external drive unit.
