Description

BRIEF DESCRIPTION OF THE DRAWING

[0022] FIG. 1 shows a schematic perspective view of a planetary gear set, having an assembly of a first component designed as an axle on a second component, wherein the first component is secured on the second component in the axial direction of the first component by respective deformations which are arranged on the same side.

DETAILED DESCRIPTION OF THE DRAWINGS

[0023] FIG. 1 shows, in a schematic and perspective rear view, a planetary gear set which is denoted overall by 1 and which is also referred as a planetary gearing. The planetary gear set 1 is used, of example, in a drive train of a vehicle which is designed as a motor vehicle and is designed, for example, as an automobile, in particular as a passenger vehicle, and is drivable by means of the drive train. The planetary gear set 1 has an assembly 2 of a first component 3 on a second component 4 of the planetary gear set 1. The second component 4 is designed here as a planetary carrier of the planetary gear set 1, wherein the planetary carrier is also referred to as a web. In the exemplary embodiment illustrated in FIG. 1, the first component 3 is designed as an axle and, in particular, as a bolt on which at least one planetary gear 5 of the planetary gear set 1 is rotatably mounted. In particular, the planetary gear set 1 comprises a plurality of first components 3 on which respective planetary gears 5 of the planetary gear set 1 are rotatably mounted.

[0024] The planetary gear set 1 comprises, for example, a sun gear (which cannot be seen in FIG. 1) which, for example, is in engagement with the planetary gears 5. At least one ring gear, not shown in FIG. 1, with which the planetary gears 5 mesh, can be provided here. The planetary carrier is connected to a shaft 6 for rotation therewith, and therefore, for example, torques can be transmitted between the shaft 6 and the planetary carrier (second component 4). Therefore, for example, torques for driving the planetary gear set 1 can be introduced via the shaft 6 in to the planetary carrier and therefore in to the planetary gear set 1 as a whole. Alternatively or additionally, it is contemplated for the planetary carrier or the planetary gear set 1 to be able to provide torques via the shaft 6.

[0025] It can furthermore be seen from FIG. 1 that the second component 4 has a receptacle 7 which is designed, for example, as a through-opening and in which at least one length region of the first component 3 is arranged. As will be explained more precisely below, in the assembly 2, the respective first component 3 is secured on the second component 4 at least in the axial direction of the first component 3, and therefore relative displacements between the components 3 and 4 in the axial direction of the first component 3 are avoided. The planetary gear 5 is rotatable here about an axis of rotation relative to the second component 4 and in particular relative to the first component 3, wherein said axis of rotation coincides with the axial direction of the first component 3.

[0026] In order now to be able to produce the planetary gear set 1 particularly simply and therefore rapidly and cost-effectively, the first component 3 has, on one axial side 8, two first deformations 9 by means of which the first component 3 is secured on the second component 4 in a first direction which coincides with the axial direction of the first component 3 or runs parallel to the axial direction of the first component 3. Relative displacements between the components 3 and 4 in the first direction is therefore avoided by means of the deformations 9.

[0027] In addition, it is provided in the assembly 2 that the second component 4 has, on the same side 8, two second deformations 10 by means of which the first component 3 is secured on the second component 4 in a second direction which coincides with the axial direction of the first component 3 or runs parallel to the axial direction of the first component 3 and is opposed to the first direction. Relative displacements between the components 3 and 4 in the second direction, which is opposed to the first direction, are therefore avoided by means of the deformations 10. The first direction is, for example, illustrated by an arrow 11 in FIG. 1, with the second direction being illustrated, for example, by an arrow 12 in FIG. 1. Since the deformations 9 and 10 are arranged on the same side 8, the deformations 9 and 10 can be produced particularly simply and therefore rapidly and cost-effectively. The side 8 here is an axial side which faces in the axial direction of the component 3.

[0028] The respective first deformation 9 is formed by the fact that the first component 3 is deformed in a respective first region or at a respective first location. The respective second deformation 10 is formed by the fact that the second component 4 is deformed at a respective second location or in a respective second region. A respective partial region of the respective component 3 or 4 is therefore deformed by the respective deformation 9 or 10. For example, the component 4 here has a respective first recess which corresponds to the respective deformation 9 and in which the respective deformation 9 or the respective partial region of the component 3 that is deformed forming the respective deformation 9 is at least partially, in particular at least predominantly or completely, accommodated. In a manner corresponding thereto, for example, the respective component 3 has a respective second recess in which the respective second deformation 10 or the respective partial region of the component 4 forming the respective second deformation 10 is at least partially, in particular at least predominantly or completely, accommodated. By means of said respective at least partial accommodation of the respective deformed partial region in the respective corresponding recess, the components 3 and 4 interact, for example, at least in a form-fitting manner, as a result of which the components 3 and 4 are secured on each other both in the first direction and in the second direction.

[0029] The first direction and the second direction are therefore what are referred to as securing directions in which the components 3 and 4 are fixed or secured on each other. In the exemplary embodiment illustrated in FIG. 1, two deformations 9 or 10 are provided per securing direction, said deformations being able to be arranged, for example, opposite each other in the circumferential direction of the first component 3 or on a circular circumference, in particular opposite each other by 180 degrees, or next to each other, in particular next to each other by 90 degrees. In the exemplary embodiment illustrated in FIG. 1, the first deformations 9 are arranged spaced apart from each other by 90 degrees or 270 degrees, with the second deformations 10 also being arranged spaced apart from each other by 90 degrees or 270 degrees. Alternatively thereto, it is contemplated for the deformations 9 and 10 to be arranged spaced apart from one another by 180 degrees in each case with respect to the circumferential direction of the first component 3. The deformations 9 and 10 are preferably arranged overall distributed uniformly in the circumferential direction of the component 3, in particular over the circumference thereof. In particular, it is contemplated to provide as many deformations 9 or 10 as desired and, for example, to divide up or to distribute them irregularly in the circumferential direction of the component 3.

[0030] The deformations 9 and 10, since they are arranged on the same side 8, can be produced particularly simply and cost-effectively by means of a device and in particular by means of precisely one actuator, wherein the actuator can be designed, for example, as a hydraulic cylinder or as a pneumatic cylinder. Overall, the planetary gear set 1 and therefore the drive train or the vehicle overall can therefore be produced particularly simply and cost-effectively.
