Definitions
- the invention relates to a power split transmission according to the closer defined in the preamble of claim 1.
- Generic power split transmissions have a continuously variable power branch and a mechanical power branch, which are summed in a summation gear.
- DE 10 2006 004 223 A1 discloses a power split transmission with a continuously variable power branch and a mechanical power branch, which are summed in a summation gear, wherein the summation gear consists of a planetary gear with a double planetary gear, two sun gears and a ring gear.
- the drive motor is arranged above the drive axles, whereby a transmission is required, which must have a large center distance between the drive of the transmission and the output of the transmission.
- the space for the width and depth of the transmission is extremely limited in work machines, so that are often used for work machines narrow, short gearbox with large center distances.
- the present invention has for its object to provide a power split transmission, which is compact and allows a large wheelbase.
- the power split transmission should have a high level of comfort when changing from a first driving range to a second driving range.
- the power split transmission has a continuously variable power branch and a mechanical power branch.
- the steplessly adjustable power branch can be designed as a hydrostatic power branch, which can have steplessly adjustable hydrostatic units of swashplate design or of a bent-axis design. These hydrostatic units can be interconnected so that they are adjustable via a common yoke. This yoke can be set so that in a first position the first hydrostatic unit is at zero displacement and the second hydrostatic unit has its maximum displacement. In the second end position of the yoke, the first hydrostatic unit is adjusted to maximum displacement and the second hydrostatic unit to zero displacement.
- stepless units as electrical units.
- the steplessly adjustable power branch and the mechanical power branch are summed up in a summation lift, the summation lift being designed as a planetary gear and having at least one double planetary gear meshing with a ring gear and two sun gears.
- the power split transmission has waves on which clutches are arranged, by means of which on the one hand a forward direction and a reverse direction are switchable and on the other hand, at least two driving ranges are switchable, within which the speed of the output is continuously variable.
- the shafts are spaced from each other and on each shaft only a single clutch is arranged, whereby a large ZF Friedrichshafen AG file 001664
- the Summ istsgethebe is arranged upstream of a coupling for a forward direction and a clutch for a reverse direction via gears, whereby the summation gear downstream of the clutches for the driving ranges can be arranged.
- the clutch for the forward drive direction is arranged coaxially to the drive of the power split transmission and the clutch for reverse driving on a shaft spaced from the clutch for forward travel.
- the ratios of the gears are preferably designed so that the shaft which is connected to the clutch for reverse drive, a higher speed than the drive shaft, which is connected to the clutch for forward drive.
- This makes it possible to arrange on the shaft with the clutch for reversing one or more consumers, such as a hydraulic pump, which already at low speeds on the drive of the transmission has a sufficiently high speed.
- This hydraulic pump can be used for example for the hydraulic supply of the transmission system as well as for cooling and lubrication. Another hydraulic pump can be used to supply the working hydraulics.
- the planetary carrier of the Summ michsgethebes which supports the at least one double planetary gear is connected via gears and the clutch for forward drive and the clutch for reversing with the drive of the power split transmission.
- a first sun gear of the Summ michsgethebes is connected to the first, continuously variable unit and the ring gear of the Summ michsgethebes is connected via gears with the second, continuously variable unit in operative connection.
- the second, continuously variable unit is connected via a clutch for a first driving range and other gears to the output of the power split transmission.
- the clutch for the first driving range in the opening direction and the clutch for the second driving range is actuated in the closing direction, whereby the second sun gear of the summation planetary gear can be brought into operative connection with the output of the power split transmission.
- the ratios of the range gearbox are selected so that at the end of the first driving range, in which the clutch for the first driving range is still closed, the clutch for the second driving range has no differential speed and thus can be closed synchronously.
- the clutch for the first drive range in the opening direction and the clutch for the second drive range is operated in the closing direction, during which the continuously variable units, such as the hydrostatic units, need only be corrected in their rotational speed, since the correction exclusively the Leakage, which arises due to the changing pressure conditions, must compensate.
- the closing and opening of the clutches runs correspondingly in the other direction.
- the second, continuously variable unit is then adjusted from the displacement volume zero in the direction of maximum displacement and the first, continuously variable unit from the maximum displacement in the direction of minimum displacement.
- Fig. 1 is a power split transmission with two driving ranges for forward drive and two driving ranges for reverse drive and
- Fig. 2 is a power split transmission with three driving ranges for forward drive and three driving ranges for reversing.
- a drive motor 1 drives the drive shaft 2 of the power splitter transmission.
- the drive shaft 2 is rotatably connected to a trained as a fixed gear spur gear 3 and a clutch for forward drive 4.
- a loose wheel 5 is arranged, which is rotatably connected to the clutch for forward drive 4.
- the spur gear 3 meshes with a spur gear formed as a fixed gear 6, which is rotatably connected to the shaft 7.
- the clutch for reverse drive 8 is arranged on the shaft 7, the idler gear 9 is arranged, which is rotatably connected to the clutch for reverse 8.
- a consumer 10, for example a hydraulic pump, is driven by the shaft 7.
- the translations are selected so that the shaft 7, and thus the load 10, a higher speed than the shaft 2.
- the idler gear 5 and the idler gear 9 mesh with the idler gear 11, which rotatably connected to the planet carrier 12 of the Summ istsplanetengethebes 13 is.
- the planet carrier 12 supports at least one double planetary gear 14, wherein the double planetary gear meshes with the ring gear 15 on the one hand and with the first sun gear 16 and the second sun gear 17 on the other hand.
- the first sun gear 16 is connected to the first, continuously variable unit 18, for example a hydrostat.
- the ring gear 15 is rotatably connected to the idler gear 19, which formed with the fixed wheel ZF Friedrichshafen AG file 001664
- Spur gear 20 meshes.
- the spur gear 20 is connected to the second, continuously variable unit 21, for example a hydrostat.
- the second sun gear 17 is rotatably connected to the spur gear 22 formed as a fixed wheel.
- the output 23 of the power split transmission is non-rotatably connected to the spur gear formed as a fixed gear 24, which is connected on the one hand via the fixed gear formed as a spur gear 25 of the clutch for the first driving range 26 and idler gear 27 with the spur gear 20, or on the other hand via the spur gear 25 the Losrad 28 of the clutch for the second driving range 29 and designed as a fixed gear spur gear 30 with the spur gear 22 is connectable.
- third driving range 34 is present, which connects the idler gear 35 with the fixed gear designed as a spur gear 36 to switch a third driving range, wherein the spur gear 36 meshes with the spur gear 30 or the spur gear 22, and the idler gear 35 meshes with the spur gear 25.

- a third driving range is switched by operating the clutch 34 in the closing direction and actuation of the clutch 26 and 29.
