Description
Technical Field
The present invention relates to a torque transmission assembly according to the preamble of claim 1.
Background
WO 2017 222 851 describes a torque transmission assembly having a torque converter and a drive disk for connecting the torque converter to a crankshaft of an internal combustion engine. The drive disk is axially curved at the outer periphery and has a starting ring gear.
Disclosure of Invention
The object of the invention is to reduce the installation space of a torque transmission assembly and to implement the torque transmission assembly more cost-effectively.
At least one of the objects is achieved by a torque transmitting assembly having the features of claim 1. The torque transmission assembly can thus take up a small amount of installation space and the starting ring gear can be fastened to the drive disk more simply and cost-effectively. The ring gear can be deformed less when connected to the drive disk and can be accommodated more precisely on the drive disk. The teeth of the ring gear can have smaller tolerances.
The torque transmitting assembly can be disposed in a driveline of a vehicle. The coupling element can be a torque converter, a transmission or a clutch, in particular a double clutch. The drive element can be an internal combustion engine or an electric motor.
The ring gear can be a starting ring gear. The ring gear can be arranged to transfer torque from the driving member to a driven member connected with the ring gear. The driven element can be a starter of the driving element.
The first tab and the second tab can form a radial seating surface for the ring gear. The ring gear can be centered on the drive disk via the first tab and the second tab. The drive disk can also have a centering region on the outer circumference for centering. The centering region can be offset in the circumferential direction from the first tab and/or the second tab.
In a preferred embodiment of the invention, it is advantageous if the first tabs and the second tabs are arranged alternately in the circumferential direction. The ring gear can thereby be stably accommodated on the drive disk. Furthermore, the two first webs can be arranged side by side in the circumferential direction and/or the two second webs can be arranged side by side in the circumferential direction.
In an advantageous embodiment of the invention, an intermediate region is arranged between the first tab and the second tab in the circumferential direction and in the axial direction. The intermediate region is preferably embodied in one piece from the base body.
A preferred embodiment of the invention is advantageous, in which the intermediate region is a radial extension of the base body. The drive disk can thus be implemented particularly cost-effectively.
In an advantageous embodiment of the invention, the first tab and the second tab are arranged immediately adjacent to each other in the circumferential direction. The first tab and the second tab can be circumferentially spaced apart from each other.
In a particular embodiment of the invention, it is advantageous if the first web and the second web extend in a corrugated manner in the circumferential direction. The first tab and the second tab may have shapes different from the corrugated shapes in the circumferential direction. For example, the first tab and the second tab may extend in a rectangular shape or a triangular shape in the circumferential direction.
A preferred embodiment of the invention is advantageous in which the ring gear is accommodated with an inner diameter on the outer circumference of the first and second webs. The first tab and the second tab can form the largest periphery of the drive disk.
In a special embodiment of the invention, it is advantageous if the drive disk has a fastening element for connection to the drive element or the coupling element. The fastening element can be arranged in a radially outer region of the drive disk. The fastening element can be embodied in one piece with the drive disk. The fastening element can protrude axially from the base body.
In a preferred embodiment of the invention, the fastening element has a radial projection for axially bearing against the ring gear. The radial projection can be arranged axially coincident with the first tab and the second tab. The ring gear can be held at least in the first axial direction or in the second axial direction by the radial projections.
In a special embodiment of the invention, it is advantageous if the first and the second webs are axially spaced apart from one another. This makes it possible to widen the bearing surface in the axial direction. The first tab and the second tab can also be arranged axially coincident. The outer peripheries of the first tab and the second tab can be axially spaced from the base.
Further advantages and advantageous embodiments of the invention result from the description of the figures and the drawing.

Detailed Description
FIG. 1 illustrates a side view of a torque transmitting assembly in accordance with an embodiment of the present invention. The torque transfer assembly 10 includes a drive plate 14 rotatable about an axis of rotation 12 and capable of transferring torque between a drive element and a coupling element. The drive disk 14 comprises a substantially disk-shaped base body 16 in which holes 18 for the passage of bolts for fixing the drive disk 14 to the drive element are arranged in a radially inner region.
The drive disk 14 comprises in a radially outer region a fastening element 20 for fastening the drive disk 14 to the coupling element. The fastening element 20 is embodied integrally with the drive disk 14 and is preferably arranged axially from the base body 16.
The torque transfer assembly 10 further includes a ring gear 22 secured to the drive plate 14. The ring gear 22 has external teeth 24 for meshing with the driven member.
The drive disk 14 includes a plurality of first tabs 28 axially disposed in a first axial direction 26 and a plurality of second tabs 32 axially disposed in an opposite second axial direction 30 on an outer periphery 36, with the ring gear 22 received thereon. In this way, the bearing surface for the ring gear 22 can be increased in the axial direction and thus the drive disk 14 can be constructed in a cost-effective and simple manner.
The first tabs 28 and the second tabs 32 are alternately arranged in the circumferential direction. Gear ring 22 is received by inner diameter 34 on an outer periphery 36 of first tab 28 and second tab 32.
A radial projection 38 is embodied on the fastening element 20, against which the toothed ring 22 axially bears in the second axial direction 30. Gear ring 22 is fixedly connected to drive disk 14 by weld 40.
Figure 2 shows a cross section along A-A in figure 1. The drive disk 14 has on the radially outer side a first tab 28 arranged axially in the first axial direction 26 and a second tab 32 arranged axially in the second axial direction 30, the first and second tabs being axially spaced apart from one another. Gear ring 22 is received by inner diameter 34 on an outer periphery 36 of first tab 28 and second tab 32.
The first tab 28 and the second tab 32 extend axially from the base 16. Gear ring 22 has a maximum axial width 42 that is greater than an axially extending region 44 spanned from first and second tabs 28, 32.
Fig. 3 shows a cross section along B-B in fig. 1. The fastening element 20 is arranged axially from the base body 16 and has a radial projection 38 for bearing axially against the ring gear 22. Gear ring 22 is connected to drive disk 14 via weld 40.
Fig. 4 shows a part of a top view of a drive disk in another embodiment of the invention. The drive disk 14 comprises a first web 28 and a second web 32 which are arranged offset from one another in the circumferential direction. The intermediate region 46 is arranged circumferentially and axially between the first tab 28 and the second tab 32. The intermediate region 46 is embodied as a radial extension of the base body.
Fig. 5 shows a part of a top view of a drive disk in another embodiment of the invention. The drive disk 14 comprises a first web 28 and a second web 32 which are arranged directly next to one another in the circumferential direction, wherein the first web 28 and the second web 32 extend in a corrugated manner in the circumferential direction.
