Definitions
- the invention relates to an actuating device for torque transmission from a drive to two output shafts with a drive, a first output shaft, a second output shaft, a coupling device, via which the rotational movement of the drive to the first output shaft and the second output shaft is transferable, and a flap device for a Internal combustion engine having a first output shaft, on which a first flap is arranged with a first rotation angle range, a second output shaft, on which a second flap is arranged with a second rotation angle range, wherein the first rotation angle range is a subset of the second rotation angle range.
- Such actuators serve, for example, to transmit torque to two flaps which are to be actuated via a common drive, but do not have the same rotational angle range to be traveled through.
- flap devices are known in which two mutually coupled flaps, each of which controls a channel and have a different rotation angle range, are actuated via a common actuator.
- Such a flap device is described for example in DE 10 2005 002 266 AI.
- an exhaust gas recirculation flap and an exhaust gas flap are actuated via a common actuator, wherein different adjustment angle ranges o of the flaps can be adjusted via two different lever linkage.
- Actuating speeds of the two flaps are to be realized. there should be easily adaptable to changing specifications and thus a use for different areas with simple modifications possible.
- one of the flaps should be able to remain at a standstill, while the other flap is rotated further, without the need for sliding coupling members are required.
- the required space is to be reduced.
- the coupling device is formed by a planetary gear which is drivable via a meshing with the planetary gear drive gear
- an actuating device is provided in which different translations can be realized depending on which elements are fixed or driven.
- the two output shafts are connected to different elements of the planetary gear, which perform defined movements that may differ from each other in different areas or may be uniform. On other components can be omitted. This results in a very high flexibility with regard to the possible uses of such an actuator.
- a flap device is provided with the two flaps can be coupled together without additional linkage so that they have different rotational angle ranges or different rotational speeds.
- Planetary gear with the drive gear engaged Such a design results in a defined translation of the ring gear to the sun gear. With appropriate attachment of the output shafts thus different or equal rotational movements over selected rotational angle ranges are generated.
- At least two toothed portions arranged one behind the other in the circumferential direction are formed on the planet gear carrier and the drive gear is formed as a stepped gear, one gear in a first rotation angle range with a first toothed portion of the planet carrier and each other gear of the stepped gear in a subsequent rotation angle range with another toothed portion of the planet carrier is engaged.
- a particularly simple design for constructive implementation of the two differing translations is achieved by the toothed portions of the planet carrier and the gears of the drive gear are arranged axially one behind the other, so that in each case a gear of the drive gear is engaged with the respective toothed portion of the planet carrier.
- the ring gear is on the successive rotational angle ranges with the first gear of the double gear in Intervention.
- the two output shafts can be arranged on a common axis without additional translations.
- the first output shaft is rotatably connected to the drive gear.
- the two output shafts offset from each other or one behind the other lying to each other can be arranged.
- the ratio of the drive gear to the ring gear is 1: 1, whereby this independent of the connection of an output shaft, this is always moved at the same rotational speed.
- the second output shaft is rotatably connected to a sun gear of the planetary gear.
- the sun gear By a suitable choice of the translations, it is possible that the sun gear and thus set the output shaft in spite of rotation of the ring gear, so that different rotational angle ranges arise in which rotates either both output shafts or only one of the output shafts.
- the sun gear is fixedly connected to a gear segment, which meshes with a follower gear segment, which is rotatably connected to the second output shaft. That way, the two can Output shafts are offset parallel to each other and an additional translation of the rotation angle between the first and second
- a particularly compact design without additionally provided bearings results when the sun gear is rotatably mounted on the first output shaft.
- sun gear has a non-toothed axial portion on which the planet carrier is radially mounted.
- the stepped drive gear as a double gear and to form on the planet two axially and circumferentially successive toothed sections, so that exactly two different rotational angle ranges of the output shafts are provided.
- the ratio of the ring gear to the planet carrier in the first rotation angle range is 1: 1, whereby the same movements of ring gear and sun gear and thus follow in this case both output shafts.
- the ratio of the ring gear to the planet carrier in a second rotation angle range is selected such that the sun gear stands still. This has the consequence that the second output shaft is stationary, while the first output shaft whose movement is coupled to the drive gear or the ring gear, performs a uniform movement over both rotational angle ranges.
- the drive is formed by an electric motor with a drive pinion, which meshes with a ratio gear, which is rotatably connected to the drive gear.
- an actuating device and a flap device with such an actuating device with which two output shafts can be actuated differently by means of a drive.
- an automatic coupling in of the movement of the second output shaft is produced even after passing through the second rotation angle range.
- different rotational movements of setting angle and speeds of the two output shafts can be realized.
- the actuator is compact and easy to assemble.
- Figure 1 shows a perspective view of a flap device according to the invention with inventive actuator with cut away housings.
- Figure 2 shows the perspective view of the flap device according to the invention with inventive actuator according to Figure 1 with partially cutaway planetary gear.
- Figure 3 shows a side view of the flap device with the actuating device according to the invention according to Figures 1 and 2 in a sectional view.
- the flap device consists of a o actuator 10, which has two output shafts 12, 14, on each of which a flap 16, 18 is arranged.
- the flaps 16, 18 each dominate a channel 20, 22 of an exhaust system of an internal combustion engine.
- a rotational movement of the output shafts 12, 14 is generated by a drive 23, which has an electric motor 24, on the output shaft 26, a drive pinion 28 is arranged.
- This drive pinion 28 meshes with a ratio gear 30, which is arranged on an axis 32 of the actuator 10.
- This axis 32 is mounted in a housing 34 of the actuator 10.
- double gear is rotatably mounted, which is rotatably connected to the transmission gear 30, or is formed with this as a triple gear.
- the drive gear 36 is operatively connected to a coupling device in the form of a planetary gear 38, which in the present embodiment, a ring gear 40, a sun gear 42, a planet carrier 44 and three arranged on axles 46 of the planet carrier 44 planetary gears 48, in a known manner in the Gears of the sun gear 42 and the ring gear 40 engage.
- a first gear 50 of the drive gear 36 engages to drive the planetary gear 38 in an outer toothing 51 of the ring gear 40.
- this first gear 50 or the second gear 52 of the drive gear 36 engages in an outer toothing 54 of the Planetenradongs 44.
- the first output shaft 12 is rotatably connected to the ring gear 40, wherein it would alternatively be possible to connect them with the meshing with the ring gear 40 first gear 50 of the drive gear 36.
- the sun gear 42 forms a first of three consecutive sections of a component 60, which is rotatable
- the third axial portion is formed as a gear segment 64 which meshes with a follower gear segment 66, which is rotatably connected to the second output shaft 14.
