- FIG. 2 is a simplified schematic diagram of the translation stage of the device for influencing the degree of distribution of the drive torque to the output shafts of Fig. 1 with a formed with a continuous toothing planetary gear.
- FIG. 1 shows a region of a gear unit 1, which has a drive torque transmitted by a drive shaft 2 and shown only schematically by a drive shaft 2 to a first output shaft 3 and a second output shaft 5 arranged coaxially therewith and symmetrically with respect to the drive shaft 2 distributed.
- the gear unit 1 is provided for installation in a motor vehicle and is designed in the embodiment shown as Schuachsgetriebetician, but it is also conceivable that a substantially analog gear unit is used as Vorderachsgetriebetician. It is also conceivable to use the present transmission unit both as a front axle transmission unit and as a rear axle transmission unit, for example in the case of a swollen motor vehicle.
- the output shafts 3 and 5 which are rotatably mounted about a common longitudinal axis X, are connected at their free ends in each case with a vehicle wheel, not shown, wherein in the installed state of the Schuachsgetriebeiki 1 a vehicle with respect to the output shaft 3 on a viewed in the vehicle front left Transmission side 7 and a vehicle wheel with respect to the output shaft ⁇ on a right side gear 9 is located.

- the Antriebsmornent of the drive shaft 2 is introduced into a differential unit 15, which is formed with a differential 17 and a differential cage 19 and connected to a device 14 for influencing the drive torque to the output shafts 3 and 5.
- the active connection between the drive shaft 2 and the differential basket 19 is a fixed to the drive shaft 2 connected drive pinion 21 with a fixed connected to the differential cage 19 ring gear 23 into engagement, wherein the differential cage 19 rotatable about the
- the differential 17 is in a known construction with two connected to the respective output shaft 3 and 5 output side bevel gears 25 and 27 and with two with the two bevel gears 25 and 27 meshing drive side. bevel gears 29 and 31 formed.

- the bevel gears 29 and 31 rotate with the bolt 33 exclusively about the longitudinal axis X. Should an output shaft in the installed state, for example, rotate faster than when cornering at different speeds rotating vehicle wheels the other, then rotate the drive side bevel gears 29 and 31 to compensate for the speed difference about the axis Y of the bolt 33, wherein the bolt 33 further passes the drive torque about its rotation about the longitudinal axis X on the two output shafts 3, 5.
- the device 14 for influencing the drive torque is provided on the output shafts 3 and 5 with two identical torque vectoring units arranged symmetrically with respect to the gear center axis Y, wherein of the two torque vectoring units in FIG. 1, only the left transmission side 7 associated torque vectoring unit 35 is shown, which will be described below.

- the first sun gear 61 is fixedly connected to the differential cage 19 and the second sun gear 63 fixed to the one output shaft 3.
- the stationary with the sun gears 61, 63 meshing planet gears 69, 71 each have a running in the axial direction of the respective planetary gear 69 and 71 through teeth 73, which both with a toothing 62 of the first sun gear 61 and with a toothing 64 of the second Sun gear 63 is engaged.
- Such trained planet gears 69, 71 can not jam with the sun gears 61, 63, due to positional error with separate teeth, whereby the reliability of the transmission unit 1 is particularly high.
- the continuous teeth 73 of the planet is very easy to manufacture, whereby the production costs are very low.
- the translation of the differential cage 19 to the first output shaft 3 is realized with a different Zahn ⁇ ahl the two sun gears 61 and 63, wherein the tooth number difference of the sun gears 61, 63 because of the same distance of the two sun gears 61 and 63 from the longitudinal axis X via a profile displacement is compensated within the sun gears 61, 63.
- the first sun gear 61 has a number of 32 teeth and the second sun gear 63 has a number of 35 teeth.
- the number of teeth is designed in such a way that the geometric changes to the sun gears 61, 63 compared to a design with two planet wheels per planet carrier offer the opportunity to work with the same distance of the sun gears 61, 63 from the longitudinal axis X.
- the brake device 51 has a lamellae brake 77 designed as a lamellae.
- the with respect to their transfer capability infinitely adjustable multi-disc brake 77 has arranged as fins on the planet carrier 65 inner fins 75 which cooperate with defined in the gear housing 11 outer fins 79 by their axial adjustability such that they can be brought into or out of frictional contact.
- the electric motor 37 actuates the brake device 51 via a transmission housing fixedly mounted by its drive shaft 83
- Intermediate gear 85 which is in engagement with the drive shaft 83 of the electric motor 37 and actuates a device 87 for axial adjustment of the multi-disc brake 77.
- the means 87 for axial adjustment of the multi-disc brake 77 is in the embodiment shown from a pivot wheel 89 which is in engagement with the intermediate 85 and how the idler 85 is disposed on the transmission center axis Y side facing away from the multi-disc brake 77, and one between the pivot wheel 89th and the multi-disc brake 77 arranged ball ramp plate 91 constructed.
- the intermediate gear 85 serves to bridge the center distance between the electric motor 37 and the swivel wheel 89. The ratio is determined by a number of teeth of the electric motor 37 and a number of teeth of the swivel wheel 89.
- the ball ramp disk 91 which is rotatably mounted and axially displaceable in the gear housing 11 and as the pivot wheel 89 is seated on the drive shaft 3, has distributed over its radius three in depth varying grooves 93.
- grooves 93 of the ball ramp disc 91 corresponding also varying in their depths grooves 95 of the pivot wheel 89 are three trained as balls 97 rolling elements, which results in a caused by the electric motor 37 turning the pivot wheel 89 axial movement of the ball ramp disk 91, such that upon axial movement in the direction of the Y-axis, the housing-fixed outer disks 79, after overcoming a clearance of the device for axial position 87, enter into a friction connection with the inner disks 75 of the coupling device 51.
- the translation stage 39 runs around the longitudinal axis X without torque transmission in the block. If a friction connection in the multi-disc brake 77 is triggered via the electric motor 37, a torque vectoring torque acting on the respective output shaft 3 or 5 is generated from the drive torque. This is done by a support of the planet carrier 65 via the braking device 51 in the gear housing 11, It is thus a torque transmission from the drive shaft 2 via the differential cage 19 and from there by means of the planet carrier 65 from the first sun gear 61 to the respective output shaft 3 and 5 connected second sun gear 63 generates, by means of which a different torque distribution to the left output shaft 3 and the right output shaft 5 can be achieved.
