Definitions

  • the invention relates to a transmission arrangement with a first transmission input shaft, a second transmission input shaft, a first countershaft, a second countershaft, a first idler gear and a second idler gear, the first idler gear and the second idler gear being arranged on the first countershaft and being non-rotatable by means of a coupling shift element are connectable.
  • the coupling switching element is arranged in a two-sided switching device.
  • a switching clutch for connecting the first idler gear to the countershaft is arranged in the two-sided switching device.
  • This two-sided switching element is arranged opposite another two-sided switching element on the second countershaft.
  • the coupling shift element is arranged as a single shift element between the first idler gear and the second idler gear. This makes it possible to design the distribution of the gears on the countershafts and the transmission input shafts in a way that differs from the prior art, which results in an overall improved use of installation space.
  • the coupling switching element can be arranged between the first loose wheel and the second loose wheel.
  • the first idler gear and the second idler gear and the gears that are in engagement therewith can be arranged closer to one another.
  • the first idler gear can advantageously be operatively connected to the first transmission input shaft and the second idler gear to the second transmission input shaft.
  • two idler gears can also mesh with fixed gears on a single transmission input shaft. Since the first idler gear and the second idler gear are to be used in the implementation of at least one winding path, however, the partial transmissions must then be connected. This can be done, for example, via the first idler gear and the second idler gear, in which they mesh with gears on both the first transmission input shaft and the second transmission input shaft and the second transmission input shaft.
  • the second transmission input shaft is preferably mounted on the first transmission input shaft. This means that it is designed as a hollow shaft and at least partially surrounds the first transmission input shaft, preferably over its entire length.
  • the first transmission input shaft can be designed as a solid shaft, but it can also be a hollow shaft.
  • the first transmission input shaft and / or the second transmission input shaft can advantageously be designed without a clutch.
  • both the first transmission input shaft and the second transmission input shaft are designed without a clutch.
  • a clutch can be arranged on the first transmission input shaft.
  • a first forward gear for forward driving operation or a sixth gear for forward driving operation can preferably be implemented.
  • the first forward gear and / or the sixth forward gear are thus designed as a winding gear.
  • both sub-transmissions are used for the implementation.
  • both transmission input shafts and one or both countershafts can be in the torque flow.
  • a third forward gear can preferably be assigned to the first idler gear when the coupling shift element is open.
  • a fourth forward gear can be assigned to the second idler gear.
  • the idler gears of the third and fourth gears are also used in the formation of the first and sixth gears.
  • a fixed gear which meshes with two idler gears, can preferably be arranged on the second transmission input shaft. By doubling the engagement, installation space can be saved in the axial direction.
  • a single fixed gear is preferably located on the second transmission input shaft.
  • the transmission can have a reverse gear shaft on which at least one reverse gear wheel is arranged.
  • Reverse gear waves are known in principle. It can be used to reverse the direction of rotation.
  • a reverse gearless gear can be arranged on the second counter shaft.
  • the direction reversal can also be achieved by using a reversing wheel on an existing shaft.
  • the reverse gear idler gear can particularly preferably be in engagement with the first idler gear.
  • the idler gear of the third gear is involved in the implementation of a total of four gear stages, namely three forward gear stages and one reverse gear stage. This quadruple use of a loose wheel means that a particularly compact size is achieved.

  • the hybrid transmission arrangement is characterized in that the transmission arrangement is designed as described.
  • the drive device can preferably be designed as an electric motor. Before geous enough, the drive device can axially parallel to the transmission input waves be arranged. It is therefore usually arranged axially parallel to the lay shafts.
  • the drive device can preferably be operatively connected to a clutch arrangement, in particular on its drive side. Furthermore, when using a triple clutch arrangement with a separating clutch and a double clutch, the point of application can be on the output side of the separating clutch and the drive side of the double clutch arrangement. As a result, both sub-transmissions of the dual clutch transmission can be driven or acted upon with torque by a single electric motor.
