Definitions
- the invention relates to a torque transmission unit, a method for producing the torque transmission unit and a hybrid transmission with the torque transmission unit.
- a ratchet wheel is usually arranged, which is non-rotatably connected to a transmission shaft.
- This ratchet wheel has teeth, usually external teeth, into which a pawl of the parking lock device can engage in order to block the rotational movement of the shaft.
- the parking lock device Insofar as the parking lock device is designed to be open during normal operation, it has the disadvantage that in the event of a failure with an interruption in the energy supply to a motor vehicle equipped with the parking lock device, the pawl does not engage in the toothing of the ratchet wheel and consequently the drive train is not blocked from rotating.
- This disadvantage is compensated for by parking lock devices that are designed to be closed during normal operation. Above a defined speed, the pawl is rejected by the ratchet wheel, although there can still be mechanical contact between the pawl and the toothing of the ratchet wheel, which can lead to increased wear. Below this defined speed, the pawl engages in the toothing of the ratchet wheel. However, this is associated with a large number of impulses acting on the toothing, which also have a disadvantageous effect in terms of wear.
- the shaft can also have at least one additional toothing to form a gear stage of a gear meshing with this additional toothing.
- this additional toothing is often an integral part of the shaft and is therefore made from the shaft material.
- Figure 1 shows a conventional pack locking device 20, with a shaft 10 shown in Figure 2.
- the pack locking device 20 comprises a shaft 10 which is rotatable about its longitudinal axis 11 and a ratchet wheel 21 arranged thereon.
- the ratchet wheel 21 has teeth 22 on its radial outside.
- the parking lock device 20 also includes a pawl 23, which can be pivoted by means of a drive unit 24, which can be moved in the movement 25 shown, in such a way that it engages in the teeth 22 of the ratchet wheel 21. It can be seen here that when the pawl 23 engages in the toothing 22, depending on the speeds achieved during engagement, high mechanical loads occur which can lead to wear, particularly in the case of a long service life.
- Figure 2 shows a perspective view of a conventionally designed shaft 10, in which the teeth 22 and thus the ratchet wheel 21 are integral parts of the shaft body are. It can also be seen here that an external shaft toothing 12 is arranged axially directly next to the toothing 22 of the ratchet wheel 21 and can form a gear stage together with a further gear wheel, not shown here.
- the illustrated shaft 10 comprises a rotor seat 16 for accommodating a rotor of an electrical rotary machine and, on the end axially opposite the ratchet wheel 21 , splines 15 for accommodating clutch components of a clutch which interacts with the shaft 10 .
- the outer shaft teeth 12 and the teeth 22 of the ratchet wheel 21 are therefore made of the same material. This makes it necessary either to design the shaft 10 as a whole from a very hard material in order to achieve the necessary wear resistance of the toothing 22 of the ratchet wheel 21, or to dispense with a higher hardness and consequently wear resistance of the toothing 22 of the ratchet wheel 21 in order to To be able to produce wave 10 efficiently overall.
- the object of the present invention is to provide a torque transmission unit and a method for producing the torque transmission unit and a hybrid transmission with the torque transmission unit, which allow the activation of a parking lock device with a long service life in an efficient, space-saving and cost-effective manner.
- the invention relates to a torque transmission unit for a hybrid transmission of a motor vehicle, comprising a shaft for mechanical coupling to a rotor of an electric rotary machine and a ratchet wheel for a parking lock device for blocking a rotational movement of the torque transmission unit, the ratchet wheel comprising teeth and the teeth being harder at least in some areas has than the wave.
- the ratchet wheel is non-rotatably connected to the shaft by means of rivets.
- the external teeth are designed to engage a pawl of a parking lock device, so that a rotational movement in a drive train of a motor vehicle can be blocked as a result.
- the toothing is an external toothing, in an advantageous embodiment with radially extending teeth. Due to the hardness of this toothing, a long service life of the toothing is guaranteed.
- the riveting can also be used to fix the two components, the ratchet wheel and the shaft, to one another axially.
- the body of the shaft can also form an external shaft toothing that has a lower hardness than the ratchet wheel, at least in some areas.
- the shaft external toothing is formed from the material of the shaft body and is consequently an integral part of the shaft, so that the shaft body and the shaft teeth form a homogeneous component.
- the advantage here is that the outer shaft toothing can be produced efficiently using a suitable manufacturing process due to the lower hardness, although the riveting according to the invention means that the unit made up of shaft and ratchet wheel is very hard in some areas, namely in the toothing of the ratchet wheel.
- the ratchet wheel is manufactured as a single part and can be manufactured in a separate hardening process that is adapted to the material and the requirements of the ratchet wheel, regardless of the shaft.
- Torque transmission unit occurring compressive stress on the soffit of a respective rivet and the consequent increase in strength of the pre-deformed material allows a very robust connection between the ratchet wheel and shaft, especially when the parking lock device is closed in the normal state.
- the rivets run essentially axially parallel to the longitudinal axis of the shaft, the rivets being arranged at least in regions in a shoulder of the shaft and at least in regions in the ratchet wheel.
- the shoulder of the shaft extends radially so that it forms an axial contact surface against which the ratchet wheel rests axially.
- At least one of the rivets has a closing head produced by forming after the rivet has been positioned in the shaft and in the ratchet wheel.
- the closing head has thus been realized subsequently after the positioning of the rivet.
- a rivet head of the rivet in question can be a button head, or a button head or a countersunk head.
- the rivet is placed in the shoulder of the shaft and in the ratchet wheel in such a way that the rivet head is on one side of one of the two components
- the opposite end section protrudes from the respective other component and is then formed into a closing head by pressure and/or impact forming.
- this rivet can also be referred to as a clinch rivet.
- a punch connects two parts to be joined by deforming the two parts and forming a flinter cut
- the rivet By driving the rivet into this blind hole and upsetting the rivet at the bottom of the hole, the rivet enlarges radially, so that it forms an undercut in the radial expansion itself. As a result, the translatory degree of freedom along its longitudinal axis is blocked for the rivet.
- the rivet also has a closing head, for example, with which it rests against the other component of the ratchet wheel and shaft, so that the two components of the ratchet wheel and shaft are fixed to one another along the longitudinal direction of the rivet.
- a further embodiment of the riveting provides that at least one of the rivets is a threaded rivet with an external thread, the external thread of which realizes a threaded connection with an internal thread in one of the two components ratchet wheel and shaft and has a closing head produced by forming, which bears against the respective other component.
- the end section of the rivet opposite the external thread protrudes from the respective other component and is formed into a closing head by pressure and/or impact forming.
- the threaded rivet has a shaped element arranged on the face side in the body of the threaded rivet for introducing a torque.
- This shaped element can in particular be a hexagon socket or a hexalobe socket.
- this shaped element is arranged in the end section axially opposite the external thread.
- This form element allows the threaded rivet to be screwed into the internal thread by applying a torque via the form element.
- the threaded rivet reaches its target position in the axial direction, it is deformed in the end section having the shaped element by pressure and/or impact deformation, so that it forms a closing head.
- a respective riveting covered by the invention is carried out in or through a shoulder of the shaft formed integrally with the shaft.
- the riveted connections in particular the threaded rivets, are suitable in particular in the case of cramped installation space conditions on the shaft, since there is relatively little space required during assembly for the loosened position of the riveted connections.
- Another aspect of the present invention is a method for Fiergna a torque transmission unit according to the invention, in which a shaft for mechanical coupling to a rotor of an electric rotary machine and a ratchet wheel for a parking lock device for blocking a rotational movement of the torque transmission unit are provided, the ratchet wheel comprises a toothing and the toothing has a greater hardness than the shaft, at least in some areas, and the ratchet wheel is connected to the shaft in a rotationally fixed manner by means of rivets.
- This method can be implemented in such a way that at least one of the rivets is positioned in the shaft and in the ratchet wheel so that it penetrates these two components, and a rivet head of this rivet rests against one of the two components shaft and ratchet wheel, and then by forming a a closing head of the rivet is formed in the end section opposite this rivet head.
- the two components, the shaft and the ratchet wheel are fixed to one another in the axial direction by the two heads formed by the rivet.
- An alternative method provides that in one of the two components, ratchet wheel and shaft, a blind hole is formed with a radial widening on the side of the hole base, and a rivet is driven into this blind hole so that it is compressed at the bottom of the hole and enlarged radially, so that it is itself forms an undercut in the radial expansion.
- the rivet also has a closing head, for example, with which it rests against the other component of the ratchet wheel and shaft, so that the two components of the ratchet wheel and shaft are fixed to one another along the longitudinal direction of the rivet.
- the method can alternatively be carried out in such a way that at least one of the rivets is a threaded rivet with an external thread, which is screwed into an internal thread in one of the two components, the ratchet wheel and the shaft, and a closing head of the threaded rivet is produced by forming, which is attached to the other component in each case applied.
- the end section of the rivet opposite the external thread protrudes from the respective other component after the screwing-in process, and is then formed into a closing head by pressure and/or impact forming.
- the threaded rivet has a shaped element arranged on the face side in the body of the threaded rivet for applying a torque
- this shaped element or the material forming this shaped element is also shaped by the pressure and/or impact deformation, so that this shaped element is formed when the closing head is formed is at least partially destroyed.
- a hybrid transmission which includes a torque transmission unit according to the invention and at least one electric rotary machine whose rotor is non-rotatably connected to the shaft Torque transmission unit is coupled, and further comprises a parking lock device for engaging in the toothing of the ratchet wheel of the torque transmission unit.
- this hybrid transmission can be designed in such a way that the axial distance between the rotor and the ratchet wheel is relatively small, in particular not greater than the diameter of the shaft of the torque transmission unit.
- the shaft of the torque transmission unit between the ratchet wheel and rotor is very short and therefore very torsionally rigid, although any angular momentum transmitted from the rotor to the shaft can still be absorbed by the ratchet wheel due to the great hardness of the teeth.
- the ratchet wheel has the additional function of axially securing a needle bearing for supporting the shaft.
- a hybrid drive arrangement can thus also be made available which has a hybrid transmission according to the invention and an internal combustion engine whose output is mechanically coupled to a connecting device of the hybrid transmission.

- FIG. 3 shows a ratchet wheel 21 which, according to the basic idea of the invention, is to be designed as a separate and hard component, at least in the area of its toothing 22 .
- the ratchet wheel 21 already has pre-drilled holes for accommodating rivets.

- FIG. 5 shows the use of this rivet 30 to attach the ratchet wheel 21.
- the rivet 30 has been pushed through a hole in a shoulder 13 of the shaft 10 and through the ratchet wheel 21, so that the rivet head 31 is seated in an undercut 33 present in the shoulder 13 .
- the rivet 30 protrudes axially from the ratchet wheel 21 .
- a closing head 32 has been produced by reshaping the rivet 30 .
- the ratchet wheel 21 is in the axial direction as well as in Circumferentially at paragraph 13 of the shaft 10 fixed.
- the ratchet wheel 21 rests against an axial contact surface 14 of the shoulder 13 .
- the paragraph 13 forms the external shaft teeth 12 on its radial outside.
- FIG. 6 shows an alternative embodiment of the torque transmission unit according to the invention.
- a rivet in the form of a so-called clinch rivet 40 has been used here.
- This clinch rivet 40 has been placed in a blind hole 41 in paragraph 13 of shaft 10 .
- This blind hole 41 has a radial widening 43 at its bottom 42 .
- the clinch rivet 40 is upset on the hole and 42 so that it is deformed into the radial expansion 43 or flows into the radial expansion 43.
- the clinch rivet 40 forms an undercut 44 in the radial widening 43, which blocks the clinch rivet 40's degree of axial freedom along its longitudinal axis.
- the clinch rivet 40 includes a rivet head 31 with which it bears against the ratchet wheel 21 . In this way, the ratchet wheel 21 is fixed to the shoulder 13 of the shaft 10.
- FIG. 7 shows a further alternative embodiment of the torque transmission unit according to the invention.
- the rivet used here is a threaded rivet 50.
- This threaded rivet 50 is screwed through a hole in the ratchet wheel 21 into an internal thread 53 in the shoulder 13 of the shaft 10, so that an external thread 51 of the threaded rivet 50 together with the internal thread 53 creates a threaded connection.
- the threaded rivet 50 comprises a shaped element 52 for applying a torque to the threaded rivet 50 on its front end facing away from the external thread 51, as can be seen in particular in FIGS.
- this shaped element 52 is a hexalobular socket.
- a closing head 32 is produced on the side of the ratchet wheel 21 by forming, in particular by impact impulses, so that the ratchet wheel 21 is also fixed in this embodiment is fixed at paragraph 13 of the shaft 10.
- the axial distance 61 of the ratchet wheel 21 to the rotor 60 is relatively small, so that the section of the shaft 10 located in between is torsionally stiff, so that rotary impulses acting on the shaft 10 are passed on essentially undamped. Due to the relatively high hardness of the toothing 22 of the ratchet wheel 21, however, rotational impulses applied in the toothing cause little or no wear.
- the rivets shown in Figures 5-7 are arranged in plurality on a partial circumference of the ratchet wheel. It can also be seen from FIGS. 5-7 that the ratchet wheel 21 fixed on the shoulder 13 of the shaft 10 forms an axial stop for a needle bearing 62 which is seated on a second shaft 63 and which supports the shaft 10 on the second shaft 63.
- roller bearing 64 can be seen in each of FIGS. 5-7 for supporting and mounting the shaft 10 in a housing 65.
- the rotor 60 of an electric rotary machine, which is arranged on the rotor seat 16, can also be seen in part.
