Definitions

  • the invention relates to a hybrid drive unit according to the preamble of claim 1.
  • the torque converter is the common technology as a starting element in a power shift transmission.
  • one possibility would be to provide a hybrid drive unit in the converter's space, where it is desirable for the hybrid drive unit to occupy the same or smaller space than the converter.
  • hybrid drive unit Such a hybrid drive unit is described in the not yet published patent application DE 102006023289.5.
  • the hybrid drive unit is arranged between an internal combustion engine and a transmission and has an electric machine and two hydraulically shiftable clutches.
  • the hydraulic or cooling fluid of the clutches is provided by the transmission and each clutch is provided a pressure compensation chamber for the dynamic pressure compensation.
  • Three supply lines and a return line, four lines in total, are provided for the supply of the two clutches with hydraulic or cooling liquid.
  • a special design of the lines is necessary, and this training requires changes in the adjacent transmission compared to a design of the lines in a transmission with converter as a starting element.
  • a hybrid drive unit for a motor vehicle which comprises an electric machine between an internal combustion engine and a vehicle transmission, which contains at least one rotor and a stator and the electric machine is operable as a motor or generator. Radially within the electric machine at least one hydraulically switchable wet-running clutch is arranged.
  • the vehicle transmission in particular a power shift transmission, has a transmission input shaft and a transmission housing.
  • a coolant such as a cooling oil, according to the invention by a central coolant supply of the transmission to the hybrid drive unit and discharged. The coolant supply passes into a substantially closed coolant circuit.
  • the coolant is used in particular for cooling the clutch, but also, for example, for lubricating the bearings arranged in the coolant circuit and as pressure fluid in the pressure compensation chamber.
  • the hybrid drive unit can be installed in a drive train with an internal combustion engine and a transmission with little effort, for example in exchange for a hydrodynamic converter. Space is saved by taking advantage of the clutch area in the coolant circuit as a pressure compensation chamber for the clutch. On a separate pressure compensation chamber can be omitted, since the coolant is provided on both sides of the clutch piston and thus an equally high rotational pressure on both sides of the clutch piston is constructed.
  • a return spring of the clutch piston can be saved, since the pressure in the coolant circuit, for example, between 4 and 6 bar is set and the clutch piston is reset as soon as the control pressure of the clutch piston drops below the current pressure in the coolant circuit. Since a powertrain can be expanded with few additions to a hybrid powertrain, this is an advantage that makes it possible to produce the hybrid technology at a reasonable cost. Also, the installation of a hybrid drive unit in current internal combustion engine vehicles is simplified without major structural changes and increases the attractiveness of hybrid technology.
  • the central coolant supply is limited by a hollow shaft rotatably connected to the transmission housing and located within the hollow shaft transmission input shaft, wherein the coolant circuit is provided outside the hollow shaft and within the rotor of the electric machine.
  • the coolant circuit is provided with seals, for example, O-rings, rectangular rings or radial shaft seals can be used.
  • the rectangular rings are used at higher pressures up to 70 bar, but have smaller leaks.
  • the radial shaft seals are only suitable for low pressures. Seals are usually provided between two relatively rotating components, all rotating seals in the coolant circuit according to the invention are arranged close to the transmission input shaft, so that the constructive maximum sliding speed of the seals, for example, 30 m / s is not exceeded.
  • the sealing rings should be provided within the first half of the inner radius of the rotor.
  • the seals are between a rotating with the transmission input shaft and a housing-fixed component and / or between one with the Rotary gear input shaft and provided with a rotating component to the rotor and / or between a rotating with the rotor and a housing-fixed component and / or between a rotating with the rotor and a rotating with a pump drive shaft component.

  • the fourth seal is provided between a component rotating with the transmission input shaft and the end of the hollow shaft at the combustion engine end, and the fifth seal is provided between a component fixed to the housing and a component rotating with the rotor of the electric machine.
  • the first four seals are exposed to higher pressures, but may have smaller leaks as they are all located in a wet room and only seal different areas with different pressures against each other.
  • the fifth seal does not have to withstand the high pressures, but must reliably seal the wet room against a drying room.
  • the coolant is supplied from the central coolant supply by at least one supplying coolant line in the coolant circuit and guided by adjacent components, such as the rotor carrier, radially outward to the inside of the rotor of the electric machine. From the inside of the rotor, the coolant is passed through the clutch, or through the pressure equalization chamber, radially inwards back to the transmission input shaft and to the central coolant supply. Within the hollow shaft, a bushing is present and within the socket is the transmission input shaft. The bushing separates the supply and discharge lines for the coolant from one another in the central coolant supply, the inflow occurring between the bush and the hollow axle and the outflow between the bushing and the transmission input shaft. Between the supply and discharge lines of the central coolant supply, the coolant is passed through the coolant circuit and passes through the first and the second and the third and the fourth seal after each other.

With a dry gap between the rotor and the stator, advantageously only slight eddy losses will occur. This can be done due to the coolant flow in the coupling region according to the invention, a pressure equalization and the space for a separate pressure compensation chamber is saved and allows a compressed design.
  • openings for passing coolant, power and signal connections for the electric machine are provided in order to adapt the transmission to the hybrid drive unit.
  • a clutch is provided in the hybrid drive unit.
  • a pressure line for supplying a medium for actuating the clutch is provided radially inside the hollow axle of the transmission, in particular in the interior of the transmission input shaft.

  • the core element of the hybrid drive unit is the electric machine 3 with its rotor 4 and its stator 5, wherein the stator 5 is rotatably connected to a housing 8.
  • the housing 8 may be a transmission housing or a separate housing of a hybrid drive unit.
  • the rotor 4 of the electric machine 3 is mounted on a rotor carrier 17, which has a hydraulically controlled wet-running multi-plate clutch 6 in its interior. Since the clutch 6 is cooled by a coolant, the interior of the rotor carrier 17 is formed as a sealed wet space.
