Definitions
- the invention relates to a drive module for a drive train of a vehicle according to claim 1.
- a drive module is known from DE 10 2016 207 104 A1, for example. This comprises an electric motor with a rotor and a coupling device with a separating clutch and a double clutch.
- the rotor is received on a rotor carrier, which is mounted with the separating clutch and the double clutch on a common bearing, which is implemented by two roller bearings that are supported on a common bearing carrier.
- the rotor is mounted via a central bearing point arranged between a bearing bracket and an intermediate shaft.
- the bearing is carried out by a central bearing point, the bearing point and the components assigned to it must be designed to be sufficiently rigid and solid. This leads to a higher weight, a larger installation space and higher costs. So that several components, for example, together with a rotor one
- Electric motor can be supported on a common bearing base, also called support bearing device, the bearing base and the components connected to the bearing base must be dimensioned to be very stable and stiff.
- the task of the bearing base is to support all mass and inertial forces as well as the external forces acting on the components, for example the actuation forces of the clutch assembly, while keeping the rotor of the electric motor in position as precisely and with low vibration as is usual and necessary for electric motors is. This is technically possible, but requires large bearings and large, thick-walled components adjoining the bearing. However, these large and heavy components do not meet the increasingly important requirements for small ones in vehicle construction
- the object of the present invention is to improve a drive module.
- the invention thus relates to a drive module for a drive train
- a coupling device with an axis of rotation for transmitting torque to a downstream support module, preferably a gearbox,
- Clutch arrangement which has at least one actuation bearing for load transmission to a respective clutch actuation means
- Coupling device is arranged radially movable component.
- the coupling device can be designed to run dry or wet.
- the coupling device can be a single coupling or a multiple coupling.
- the design of a double clutch or one is also possible
- the at least one clutch actuation means can in particular be a lever spring, a plate spring, a pressure pot and / or a pressure piece.
- clutch actuation means that realize a leverage effect
- clutch actuation means without a leverage effect The friction means arrangement has at least two interacting friction surfaces. In particular, this can take place via two friction surfaces on the actual components or via a separate friction body which is arranged between the components with a friction effect. In particular, these two friction surfaces cannot be moved axially with respect to one another along the axis of rotation.
- the friction surfaces can be optimized by coating the component surface or by using special materials, such as friction linings, for example, in order to achieve the desired friction properties.
- the formulation along the axis of rotation also includes axes parallel to that of the axis of rotation.
- the invention is to provide a friction means assembly through which
- Radial vibrations of the rotatable components of the drive module can be dampened.
- the friction means arrangement is ideally formed by two contact surfaces which are orthogonal to the axis of rotation of the drive module and which are pressed against one another by a normal force acting in the axial direction.
- the friction arrangement tends to shift the two contact surfaces of the
- Friction means arrangement relative to one another. The friction between the two contact surfaces removes energy from the shifting unit. As a result, the vibration amplitudes of the structural unit are lower and
- the friction means arrangement can be arranged on the clutch actuation system, since this is usually the component furthest away from the center of rotation of the tilting vibrations.
- the system is damping
- Friction means arrangement for example, on a gear housing, a Clutch housing, a clutch actuation system or a
- Arranged transmission input shaft which is located in the vicinity of the support module, in particular a transmission, on the output side of the drive module.
- Center of rotation or instantaneous pole which is arranged with a rotation vector aligned orthogonally to the axis of rotation.
- the center of rotation of the tilting vibrations is in the area of the common
- Friction means arrangements on an axially spaced from these components
- the center of rotation of the tilting vibrations can possibly also move to a different location
- friction means arrangement so that the friction means arrangement continues to be spaced from the center of rotation of the tilting vibrations. It is not relevant on which side of the center of rotation of the tilting vibrations the friction means arrangement is arranged. The greater the distance between the center of rotation of the tilting vibrations and the friction arrangement, the greater the damping effect of the
- the transmission represents an element which does not belong to the rotating and vibration-prone structural unit of the drive module and on which the drive unit can be supported.
- the invention can also be used for
- Drive modules are used to which, instead of a gearbox, another output element is connected, on which the drive module can be supported.
- the clutch actuation system is an element coupled to the rotating and vibration-prone structural unit of the drive module.
- Friction means arrangement consists in the fact that the tilting vibrations or the
- Tilt amplitudes of the drive module can be reduced in a manner comparable to that with an additional rigid support, but due to the radial displaceability in the friction means arrangement, no undesired radial tension between the
- common bearing base also called support bearing device, and the
- the common bearing base is attached to a housing component, for example the hybrid module housing, and the additional support is attached to another housing component, for example the
- Electric motor is attached and the additional support point on one
- a possible concentricity error or coaxiality error of components of the drive module can be compensated for by the radially displaceable friction means arrangement.
- the common support bearing device also called the bearing base, determines the axis of rotation of the rotatable structural unit of the drive module. Due to the displaceability of the friction arrangement, geometric
- the friction means arrangement is each provided with an additional one
- Transmission-side support point connected. These support points are each equipped with a bearing that can transmit radial forces. In addition, there is a point in the bearing or near the bearing where components can move against each other in the axial direction. In principle, everyone comes as a camp Consider bearing designs that can transmit radial forces. These can be needle bearings, needle sleeves, deep groove ball bearings, cylindrical roller bearings, for example. However, other storage types can also be used at these points.
- An axially displaceable positioning system can compensate for axial tolerances, as well as elastic deformations or thermal expansions that occur when the hybrid module is in operation.
- the axially displaceable positioning system can also be used as an assembly interface between the hybrid module and the transmission. This makes it possible to mount the separating clutch and the double clutch on the rotor of the electric motor so that the clutches are part of the hybrid module. If the hybrid module is connected to a support module, in particular a transmission, the part of the support point that is located on the clutch becomes the part of the support point on the axially displaceable positioning system
- the axial displaceability and the assembly interface can be realized, for example, by a clearance or transition fit between the inner or outer ring of a bearing and the component forming the bearing seat for this bearing ring, in the case of the bearing connected to the friction arrangement.
- the axial displaceability and the assembly interface can also be implemented in the bearing connected to the friction means arrangement, for example, through an axial displaceability of the rolling elements relative to the component forming the raceway for these rolling elements.

- Transmission input shafts 42 The transmission input shafts 42 can be designed as hollow and solid shafts.
- the illustrated drive module 10 includes the Electric motor 30, a separating clutch 44 and a double clutch 46.
- Separating clutch 44 and the double clutch 46 are mounted on the rotor 32 of the electric motor 30 and are supported together with it by the bearing base consisting of two angular contact ball bearings 48a, 48b as a bearing support device 38 on the axis 50 belonging to the module housing 28.

- the friction means arrangement 26 between the central plate 22 and the support ring 56 is acted upon by force in the axial direction by the plate spring 60 acting between the transmission input shaft and the friction means bearing 52.
- the force of the plate spring 60 not only compresses the contact surfaces of the friction means arrangement 26, but also the friction means bearing 52 is under an axial preload.

- Friction means arrangement 26 is arranged, which is supported on the support module 14 designed as a transmission housing. If radial or tilting vibrations of the rotatable assembly occur, the friction element bearing 52 connected to the clutch device 12 moves together with the rotatable assembly in the radial direction, whereby the friction element arrangement 26 attached to the friction element bearing 52 is attached to the
- This friction means arrangement 26 is advantageous because it is axially far removed from the components of the common support bearing device 38 and the components carrying the common support bearing device 38. In addition, this friction means arrangement 26 can adjust itself well to the axis of rotation D defined by the common friction means arrangement 26, since the friction means arrangement 26 is not additionally affected by the movements of the

- Helical compression springs 66 are centered on one side on the clutch cover 62 and are also centered on the sides facing the support element, a displacement of the support element relative to the clutch cover 62 leads to a plastic deformation of the helical compression springs 66 orthogonal to their longitudinal axis. The restoring forces that the helical compression springs 66 by the
- Exerting a deflection orthogonally to their longitudinal axis on the support element and the cover can be designed so that the structural units which can be displaced relative to one another by the friction means arrangement 26 do not move in the circumferential direction
- the transmission input shaft 42 is to be inserted into the support element in which the friction center bearing, in particular as a needle bearing, is already located.
- the assembly sleeve does this with its conical inner contour
- the drive module 10 according to FIG. 6 is similar to the drive module 10 according to FIG. 3.
- the embodiment according to FIG. 6 has two friction means arrangements 26 on both sides of a friction means bearing 52.
- one friction means arrangement 26 is advantageously provided between a rotatable structural unit and the friction means bearing 52 and the other friction means arrangement 26 is provided between the friction means bearing 52 and the support module 14.
- the friction center bearing 52 can align itself in such a way that the axis of rotation of the
- Friction center bearing 52 as precisely as possible with the axis of rotation of the rotatable
- a friction means arrangement 26 can then compensate for the geometrical deviation of the rotatable parts and the other
- Friction means arrangement 26 can compensate for the geometrical deviations of the housing.
- a plurality of connecting elements 54 distributed around the circumference are arranged on the clutch cover 62 of the double clutch 46, which extend through the clutch actuation means 20, in particular a feather spring, arranged on the output side and at the ends of which leaf springs 58 are attached.
- a support ring 56 which has a friction means arrangement 26, is fastened to the leaf springs 58 via step bolts.
- a friction ring 57 connected to the friction center bearing 52 rests on this friction means arrangement 26.
- Friction center bearing 52 is a friction means arrangement 26, which is located on
- Support module 14 is supported.
- the leaf springs 58 not only connect the friction center bearing 52 to the coupling device 12, but they also provide the axial force which presses the two friction center arrangements 26 together on both sides of the friction center bearing 52. If radial or tilting vibrations of the rotatable structural unit occur, the support ring 56 connected to the coupling device 12 moves together with the rotatable structural unit in the radial direction, whereby in at least one of the two friction means arrangements 26 creates friction. This ensures the damping of the oscillating drive module 10, also called a structural unit.
- the formulation along the axis of rotation D also includes axes parallel to that of the axis of rotation D.
- All exemplary embodiments show hydraulic clutch actuation systems. However, the invention can also be applied, for example, to pneumatic, electromechanical and mechanical clutch actuation systems 16. Actuating bearings 18, actuating system housings or actuating system assemblies have a multiplicity of clutch actuating systems 16, regardless of the operating principle.
- the axial and radial directions refer to the axis of rotation D about which the electric motor and the coupling device 12 rotate.
