Definitions

  • Electric motor drive in particular for automatic transmissions in commercial vehicles
  • the invention relates to an electric motor drive, in particular for automatic transmissions in commercial vehicles, according to the preamble of the main claim.
  • Electromotive drives are generally known, and they are used especially in the motor vehicle sector for adjusting a wide range of vehicle components. This applies, for example, to the adjustment of vehicle seats, windows and sliding sunroofs or the adjustment of mirrors.
  • the electric motor drives then take over the clutch and shift function required for shifting the transmission and replace the manual shift to be carried out by the driver.
  • the actuating forces to be applied in this case can be achieved at least in the case of passenger cars with relatively simple manual transmissions using the conventional small electric motors.
  • Actuation of the clutch and automatic shifting of the transmission require far higher forces.
  • drives with correspondingly larger and more powerful electric motors are required, with large motors generally having a much lower dynamic than small motors.
  • a high level of dynamics is required because, for example, certain switching times in trucks are not exceeded when changing gears, or interruptions in traction should be kept as short as possible.
  • the electromotive drive according to the invention with the features of the main claim has the advantage that the high dynamics that are available when only a single, relatively small electric motor is used are maintained and at the same time the available actuating force or the torque is increased considerably ,
  • the transmission gear unit is a worm gear unit.
  • gears are also conceivable, for example spur gears or helical gears.
  • the worms which are operatively connected to a worm wheel of the worm gear unit, and the adjoining armature shafts are arranged parallel to one another.
  • a particularly compact design of the drive according to the invention is then obtained, and the engagement points of the worms on the worm wheel are, for example in the case of two electric motors, evenly offset from one another by 180 °. The latter ensures an optimal distribution of the load on the worm wheel.
  • a similarly optimal distribution of the load on the worm wheel is achieved if the armature shafts and the worms connected to them are arranged symmetrically, for example in a star shape, around the worm wheel.
  • This arrangement also has the advantage that more than two electric motors can be easily connected to the worm gear unit.
  • the at least two electric motors are connected to a control unit, there is the advantageous possibility of controlling the at least two electric motors in a very targeted manner and in accordance with the respective requirements.
  • the optimum switching time can be determined by a central control unit and this can be sent to the control unit as a corresponding signal.
  • the control unit is then in able to control the electric motors according to these specifications.
  • the at least two electric motors can be controlled independently of one another. This enables the optimum adjustment of the power or the actuating force available on the drive of each individual motor to the current requirements.
  • At least one of the at least two electric motors can be uncoupled from the gear unit or coupled into the gear unit, for example via a clutch. Even then, the required actuating force can be dosed in accordance with the current requirements.
  • the armature shafts and the screws are divided in two and are operatively connected to one another via a gear arrangement. This opens up the possibility of operating the electric motors, for example, at different speeds, the rotational speeds of the screws being able to be coordinated with one another by the choice of the gear ratio.
  • the division into two makes it possible, for example, that different motors acting on the gear unit with different dynamics or performance characteristics can be used and switched on as required.
  • FIG. 1 shows a schematic illustration of an electromotive drive according to the invention in plan view
  • Figure 2 shows a second embodiment also in plan view
  • Figures 3 to 5 are schematic representations of various arrangements of the screws connected to the armature shafts.
  • FIG. 1 shows an electromotive drive according to the invention, in particular for automatic gearboxes in commercial vehicles, with a drive unit 10 and a worm gear unit 12 connected to it.
  • the drive unit 10 consists of two electric motors 14, the schematically illustrated armature shafts 16 with adjoining screws 18 are arranged parallel to one another.
  • the worm gear unit 12 has a worm wheel 20, in which the two worms 18 engage at two engagement points 22 which are offset by 180 ° to one another.
  • the armature shafts 16 and thus also the worms 18 rotate around the arrow directions A and B shown and set the worm wheel 20 in a rotation in the direction of the arrow C.
  • the torque acting on the worm wheel can be doubled here, not only the high dynamics of the two electric motors 14 being used but also the load acting on the teeth of the worm wheel 22, not shown, being evenly distributed.
  • the worm wheel 20 is also connected to an output part 24, via which the actuating force is transmitted to a gearbox, not shown.
  • a control unit 26 is provided, which is connected to the two electric motors.
  • the two electric motors 14 can be controlled with this control device 26.
  • it can receive data from a central control unit 28 and use this data to control the two electric motors in a targeted manner and in accordance with the respective requirements.
  • Control unit 26 detects, for example, that an increased force or. Torque is required, it can cause the two electric motors to work according to their respective maximum power. On the other hand, if the control unit 26 detects that only a low power is required, the control can initiate a more energy-saving operation.
  • FIG. 2 shows a second exemplary embodiment of a device according to the invention, exactly as in FIGS following figures the same features are provided with the same reference numerals.
  • FIG. 2 differs from that of FIG. 1 essentially in that a coupling 30 is arranged between the armature shafts 16 and the associated screws 18.
  • This clutch 30 is only shown schematically, since it is not the specific design that is decisive, but only the principle implemented with it: it makes it possible to selectively decouple one or the other electric motor 14 from the worm gear unit 12. In the case of a non-self-locking worm gear, the worm gear unit 12 is then only driven by one electric motor 14, while the worm 18 of the other electric motor 14 is simply moved.
  • FIG. 3 A third exemplary embodiment is shown schematically in FIG. 3, in which a star-shaped arrangement of the armature shafts 16 or the worms 18 of three connected therewith
  • Electric motors 14 is shown. Here the engagement points 22 are offset from one another by 120 °.
  • FIG. 4 Another possibility of the arrangement is shown in FIG. 4, in which two exactly as in FIGS. 1 and 2
  • Screws 18 are operatively connected to the worm wheel 20 and the engagement points 22 are offset by 180 °.
  • the electric motors 14 are not on one side, but are brought to the gear unit 12 from both sides on the left and right.
  • a fifth exemplary embodiment is shown schematically in FIG. 5, in which the snow screws 18 and the armature shafts 16 are each operatively connected via a gear unit 32.
  • the device according to the invention is of course not limited to the exemplary embodiments shown in FIGS. 1 to 5, rather it is crucial that the advantages described at the outset come into play according to the main claim.
