Definitions
- the invention relates to a drive device for motor vehicles with a drive unit, which is operatively connected via a differential gear with two output shafts and an angle drive, via which the drive device is operatively connected to a drive shaft, wherein the drive unit comprises a rotor of an electric machine, which operatively connected to the differential gear and wherein the angle drive is formed by a driven by means of the drive shaft pinion shaft and by a standing with a pinion head of the pinion shaft meshing crown gear while a rotational axis of the pinion shaft extends transversely to a rotational axis of the rotor and the ring gear.
- Such a drive device is described in DE 10 2004 024 086 A1.
- These drive devices are preferably used in hybrid vehicles for driving vehicle axles.
- the drive shaft is accordingly the cardan shaft or an intermediate shaft between a transfer case and the drive device in the axle drive, at the end of which the pinion head of the angle drive is usually formed.
- sufficient space must be available in the vicinity of the driven axle, which is not always available in every case. Description of the invention
- the object of the invention is therefore to provide a drive device with which the problems are to be eliminated, which occur in connection with confined space in the vicinity of an axis driven by the drive device.
- the object has been achieved according to the features of claim 1.
- the invention provides that an axis of rotation of the drive shaft and the axis of rotation of the pinion shaft extend parallel to the axis at a distance from each other. A coaxial agreement of the axes of rotation of the drive shaft and the pinion shaft or the pinion head is thus no longer absolutely necessary, because the drive shaft and the pinion shaft according to the invention are operatively connected to each other in operative connection.
- the differential and the drive unit can be adapted to the available space in the vicinity of the axis also with offset of the input shaft (pinion shaft) are arranged to the drive shaft.
- a geared active connection is a power transmitting connection.
- Examples of this in this case are belt or chain drives or, as one embodiment of the invention provides, toothed wheels are meshed with one another.
- the center distance of the gears corresponds to the axis-parallel offset between the axis of rotation of the drive shaft and the axis of rotation of the pinion shaft.
- One of the gears preferably with straight or oblique spur toothing, sits, for example, fixed or with the interposition of a one-way clutch, which may also be switchable, directly on the drive shaft.
- the other gear is provided with a corresponding toothing and is preferably fixed or with the interposition of a one-way clutch on the pinion shaft.
- Another advantage of the invention is that with the geared connection to the drive shaft applied power parameters such as speeds and Torques to the pinion shaft down or can be translated, whereby the characteristics of the drive device in addition to the other gear stages influenceable and the arrangement is thus variable designable.
- an embodiment of the invention provides that a transmission ratio of the number of teeth of the second gear to the first gear is smaller than the pay attention 1.
- a further embodiment of the invention provides for a transmission ratio of the number of teeth of the ring gear to the pinion head, which is greater than the pay attention 1.
- Figure 1 is a highly simplified and not to scale representation.
- a drive device 1 for an otherwise not further illustrated motor vehicle is provided with a drive unit 2, which is operatively connected via a differential gear 3 with two output shafts 4 and 5.
- the drive unit 2 surrounded by a housing 6, in which at least one electric machine 7 and a geared connection 8 not described in more detail is received between the rotor 9 of the electric machine 7 and the differential gear 3.
- the differential gear 3 is in this case a planetary gear, but may also be a classic bevel gear differential or a hybrid of planetary gear sets and elements of the bevel gear differential.
- the differential gear 3 is formed from a planetary stage 10 and the actual differential 1 1.
- the planetary stage 10 provides a planet carrier 12, on which a set of planetary gears 13 is rotatably mounted. Of the set planet gears 13 only one is shown.
- the planetary stage 10 has a ring gear 14 which is fixedly supported relative to the environment 15, for example with respect to a housing of the drive device 1.
- the differential 1 1 is formed from a differential cage 16, which is another planetary carrier in this case, from two sets of planetary gears 17 and 18 and two sun gears 19 and 20.
- the planet gears 17 are rotatably mounted on the differential cage 16 rotatably about its own axis, while there is a respective planetary gear 17 of the one set with a planetary gear 18 of the other set in meshing engagement.
- each planetary gear 17 of the one set is in meshing engagement with the sun gear 19 and each planetary gear 18 in mesh with the sun gear 20.
- the sun gear 19 is rotatably coupled to the output shaft 4 about the rotation axis 21.
- the output shaft 4 is operatively connected to a vehicle wheel, not shown.
- the sun gear 20 is rotatably coupled to the output shaft 5 about the rotation axis 21.
- the output shaft 5 is operatively connected to a vehicle wheel, not shown.
- the drive device 1 is operatively connected via an angle drive 22 with a drive shaft 23.
- the angle drive 22 has a drive shaft 23 driven by the pinion shaft 24, on which a pinion head 25 is seated.
- the pinion head 25 is a bevel gear and is in meshing engagement with the toothing of a ring gear 26.
- the ring gear 26 is aligned coaxially with the axis of rotation 21 of the rotor 9 aligned with the planet carrier 12.
- the axis of rotation 27 of the pinion shaft extends transversely to the axis of rotation 21 of the rotor 9 and the ring gear 26.
- the axis of rotation 28 of the drive shaft 23 and the axis of rotation 27 of the pinion shaft 24 extend at a distance from each other and parallel to the axis.
- the pinion shaft 24 is cantilevered, which means that the pinion head 25 is axially supported on one side by two axially spaced bearing points 29 and 30. It is also conceivable that the pinion head is additionally mounted at its free end, so that it is supported axially between two bearing points.
- the drive shaft 23 and the pinion shaft 24 are operatively connected to each other in operative connection.
- the geared connection is a spur gear of two gears 32 and 33.
- the gear 32 is rotatably connected to the drive shaft 23 and the other gear 33 is firmly seated on the pinion shaft 24th reference numeral
