Definitions

  • the invention relates to a transmission for a motor vehicle having a transfer gearset, a main gearset, a drive shaft, an output shaft and at least five shift elements.
  • the invention further relates to a hybrid powertrain for a motor vehicle.
  • the switching elements are, for example, clutches or brakes here.
  • Such transmissions are mainly used in motor vehicles to adjust the speed and torque output characteristics of the drive unit to the driving resistance of the vehicle in a suitable manner.
  • An automatic transmission for a vehicle according to the preamble of claim 1 is known from the disclosure DE 102 13 820 A1. However, this automatic transmission does not have an electric machine.
  • the transmission should have a simple and compact design.
  • the Vorschaltradsatz is adapted to provide an increased speed compared to the speed of the drive shaft on a fifth shaft.
  • the fifth shaft is connectable to the fourth shaft of the main gearset.
  • the fifth shaft is connectable to the first shaft of the main gearset.
  • the drive shaft is connectable to the first shaft of the main gearset.
  • the fourth switching element the drive shaft is connectable to the second shaft of the main gearset.
  • the fifth shift element the fourth shaft of the main gearset is rotationally fixed by the fourth shaft is connected to a housing or with another rotationally fixed component of the transmission.
  • the third shaft of the main gear is permanently connected to the output shaft of the transmission.
  • the Vorschaltradsatz is formed as a planetary gear, which has a first element, a second element and a third element.
  • the first element is formed by a sun gear of the planetary gear set, and is permanently fixed against rotation.
  • the planetary gear set is designed as a minus wheel set
  • the second element is formed by a web of the planetary gear set, and the third element by a ring gear of the planetary gear set.
  • the planetary gear set is designed as a plus-wheel set
  • the second element is formed by the ring gear of the planetary gear set, and the third element by the web of the planetary gear set.
  • the second element is permanently connected to the drive shaft, while the third element forms part of the fifth shaft. Due to the design of the transfer gearset as planetary gear, the transmission is also suitable for very high performance, since a comparable spur gear for high performance would be extremely difficult.
  • the transmission has a sixth switching element.
  • the sixth switching element By closing the sixth switching element, the second shaft of the main gearset can be fixed in a rotationally fixed by the second shaft of the main gearset is connected to the housing or with another non-rotatable component of the transmission.
  • the sixth Switching element is open in all forward gears of the transmission.
  • the sixth switching element By the sixth switching element, the formation of mechanical reverse gears is made possible. This is only partially necessary in the subject gear, as a reverse gear is possible by operation of the electric machine against a preferred direction of rotation and inserting one of the forward gears.
  • the sixth switching element can easily provide at least one mechanical reverse gear between the drive shaft and the output shaft.
  • a planetary gear set includes a sun gear, a land and a ring gear. Rotatably mounted on the web are planet gears, which mesh with the toothing of the sun gear and / or with the toothing of the ring gear.
  • a minus wheel set denotes a planetary gear set with a web on which the planetary gears are rotatably mounted, with a sun gear and with a ring gear, wherein the toothing of at least one of the planet gears both with the toothing of the sun gear, as well as meshing with the teeth of the ring gear, whereby the ring gear and the sun gear rotate in opposite directions of rotation when the sun gear rotates at a fixed web.
  • 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.
  • the toothing of the outer planetary gears also meshes with the teeth of the ring gear. This has the consequence that rotate at a fixed land, the ring gear and the sun gear in the same direction.
  • Fig. 2 shows a speed diagram of the transmission according to the first embodiment.
  • the second wave W2 is associated with the second sun gear E122.
  • the third wave W3 is associated with the web E22.
  • the fourth wave W4 is associated with the first ring gear E321.
  • the operating mode GEN is suitable for stand loading of the motor vehicle when the vehicle is at a standstill.
  • only the seventh switching element KO is closed, wherein a drive unit connected to the connection shaft AN can drive the electric machine EM.
  • no gear is engaged, whereby no power is transmitted to the output shaft GW2.
