Definitions
- the invention relates to a drive train of a drive for the motorized adjustment of a closure element of a motor vehicle according to the preamble of claim 1, a drive for the motorized adjustment of a closure element of a motor vehicle with such a drive train according to claim 14 and a closure element arrangement of a motor vehicle such a drive according to claim 15.
- the drive train of a drive in question is used in the context of the motorized adjustment of a closure element of a motor vehicle.
- closure elements can be, for example, doors, in particular sliding doors, or flaps, in particular rear hatches, trunk lids, engine hoods, cargo space floors or the like, of a motor vehicle.
- the term “closure element” is to be understood broadly in the present case.
- the drive train in question serves to guide the power flow of the drive force generated by a drive motor of the drive.
- the drive train can have drive components such as shafts, gears, clutches, brakes or the like.
- the known drive train (DE 10 2017 101 325 A1), from which the invention is based, is part of a spindle drive for the motorized adjustment of a tailgate of a motor vehicle.
- a clutch mechanism which is designed as an overload clutch, is assigned to the drive train.
- the clutch mechanism is connected between two drive components, one of which is a motor-side gear shaft of an intermediate gear of the drive train and the other of which is a spindle of a spindle-spindle nut gear facing away from the motor.
- the coupling mechanism has a frictional engagement mechanism which, on the one hand, allows the tailgate to be held securely in intermediate positions and, on the other hand, allows the tailgate to be manually adjusted after a breakaway torque of the frictional engagement mechanism has been overcome.
- the “breakaway torque” is the maximum torque to be applied that is necessary to create an adhesive bond between two components that can be rotated relative to one another and caused by static friction to separate, whereby the static friction changes into sliding friction when the breakaway torque is reached.
- the structural design of the known drive train basically guarantees a relatively high level of operational reliability and, with regard to the manual adjustability, a high level of user comfort.
- the clutch mechanism takes up a comparatively large amount of space in the direction of the drive axis of the drive train.
- a separate pressure mechanism is provided with axially acting helical compression springs, that is to say acting along the drive axis, which axially pretension the frictional engagement elements against one another. This increases the technical length of the drive train and thus of the drive.
- the invention is based on the problem of designing and developing the known drive train in such a way that the technical length of the drive is reduced.
- the fundamental consideration is to provide, instead of an axial, radial frictional engagement between the frictional engagement elements of a friction engagement mechanism that is part of a coupling mechanism of the drive train.
- the normal force generating the frictional torque acts radially, that is to say orthogonally to the drive axis, and not along the drive axis.
- a pressure mechanism acting in the axial direction is therefore no longer required, which correspondingly reduces the technical length and thus the installation space required axially.
- a “tolerance ring” is a radial, ring-shaped or sleeve-shaped intermediate element that is arranged in a gap between two components aligned concentrically to one another, here two frictional engagement elements, in order to achieve a friction fit between the two concentrically aligned components. testify that allows a torque transmission.
- a tolerance ring has a non-uniform, ie not completely cylindrical, outer and / or inner contour in the circumferential direction, that is around its central axis, with which the tolerance ring provides a defined spring force in the radial direction.
- a tolerance ring Since a tolerance ring has a relatively small thickness in the radial direction, it takes up relatively little installation space in the radial direction, even compared to helical compression springs.
- a tolerance ring preferably has a thickness of at most 5 mm, preferably of at most 3 mm, more preferably of at most 2 mm, more preferably of at most 1.5 mm.
- the "thickness" means the difference between the maximum outer radius and the minimum inner radius of the toe ring.
- the frictional engagement elements are arranged concentrically to one another at least in sections and that the middle frictional engagement element is a tolerance ring and is radially clamped to provide a frictional connection between the two further frictional engagement elements.
- the arrangement of the frictional engagement elements of the frictional engagement mechanism, which is part of the clutch mechanism, is therefore particularly such that the one frictionally engaging frictional engagement element with the central frictional engagement element is arranged radially inside the central frictional engagement element and radially on the outside with the central frictional engagement element. Ren frictional engagement element is in frictional engagement.
- the other frictional engagement element in frictional engagement with the central frictional engagement element is arranged radially outside the central frictional engagement element and in frictional engagement with the central frictional engagement element radially on the inside.
- a radial frictional engagement preferably exclusively a radial frictional engagement, is thus produced between frictionally engaged frictional engagement elements.
- the jammed middle frictional engagement element which is proposed as a tolerance ring, generates a radial clamping force, in particular a radial spring force, which brings about the frictional connection.
- a separate pressing mechanism for generating a pressing force of the frictional engagement elements towards one another is therefore not required. The pressing force is brought about by the radial clamping or spring force.
- Claims 2 and 3 define a special configuration of the central frictional engagement element, in particular a tolerance ring, with a plurality of radial elevations. These protrude in the radial direction with respect to the side edges and in particular a circumferential flat edge of the central frictional engagement element that forms the side edges and / or with respect to the central friction engagement element, otherwise, radially.
- the sections in the circumferential direction between the radial elevations preferably extend cylindrically around the drive axis, that is to say run on a cylinder jacket of a circular cylinder with a cylinder axis coaxial with the drive axis.
- the radial elevations are preferably embossed areas, that is to say have been produced by embossing, so that corresponding depressions or beads are formed on the other radial side.
- the elevations and thus the radially furthest protruding points of the central frictional engagement element then preferably form one friction surface of the central friction engagement element, while the other radial side forms the other friction surface of the central friction engagement element.
- the latter friction surface is in particular completely cylindrical, that is to say flat.
- Claims 4 and 5 relate to particularly preferred applications of the clutch mechanism. According to claim 4, this is preferably designed as an overload clutch. According to claim 5, a breakaway torque between two of the frictionally engaged frictional engagement elements is greater than that of the other two frictionally engaged frictional engagement elements, so that in the event of an overload between the one pair of frictional engagement elements or the associated pair of friction surfaces, static friction continues to exist a non-rotatable connection remains, whereas sliding friction occurs on the radially other side and the non-rotatable connection is canceled.
- the non-rotatable connection that continues to exist on one side in this overload case is preferably ensured by the fact that, during assembly, the central frictional engagement element or the tolerance ring, in particular with the elevations, is pressed into one of the two frictional engagement elements, in particular pressed radially inward .
- the elevations dig into the material of the frictional engagement element therewith.
- the middle frictional engagement element is mounted by means of a press fit on one of the frictional engagement elements, in particular on that of the friction engagement elements to which the elevations point.
- Claims 6 to 12 relate to particularly preferred configurations of the individual friction-locking elements.
- Claim 6 defines in particular the preferred material of at least one of the friction surfaces, preferably all of the friction surfaces, of the frictional engagement elements. It is particularly preferably metal.
- claims 7 and 8 relate to particular configurations of the central frictional engagement element or tolerance ring, and claims 9 to 12 particularly preferred configurations of the other two friction engagement elements.
- the coupling mechanism is coupled to the drive component on the engine side and / or the drive component remote from the engine by means of a plug connection.
- the plug connection is formed in particular by a claw coupling.
- the coupling mechanism can be produced as a preassembled unit and can be connected to the respective drive component in a particularly simple manner.
- a drive for the motorized adjustment of a closure element of a motor vehicle which has a drive train as proposed. Reference may be made to all statements on the proposed drive train, provided that they are suitable for explaining the drive.
- the drive is particularly preferably designed as a spindle drive, the clutch mechanism and / or frictional engagement mechanism of the proposed drive train being connected between a drive motor and a spindle-spindle nut gear of the drive.
- a closure element arrangement of a motor vehicle with a closure element adjustably coupled to the body of the motor vehicle and with at least one proposed drive for claims the motorized adjustment of the closure element is also of independent importance.

- the coupling mechanism 7 provided according to the proposal is best suited for an arrangement in which the drive 2 is designed to be self-locking, that is to say not able to be driven back. In order to nevertheless enable manual adjustment of the tailgate 3, the coupling mechanism 7 is designed as a slip clutch, so that a corresponding manual adjustment of the tailgate 3 is possible after a frictional force has been overcome.
- the drive train 1 can furthermore have a braking mechanism which is also used in the coupling Release mechanism 7 can be integrated or in any case can be arranged in a common housing with the coupling mechanism 7.

- the motor-side coupling piece 7a is here and preferably with a separate coupling counterpart 11a of the motor-side drive component 11 and the coupling piece 7b facing away from the motor with a separate coupling counterpart 12a of the motor-remote drive component 12 in the circumferential direction U positively coupled.

- Conscentric at least in sections means that at least the sections forming the friction surfaces of the respective frictional engagement elements 8, 9, 10, ie the surfaces of the friction engagement elements 8, 9, 10 which are in frictional engagement with one another, are arranged concentrically to one another.
- the middle friction-locking element 8 is a tolerance ring 13 and is radially clamped to provide a frictional connection between the two further friction-locking elements 9, 10.
- “Radially jammed” means that a radially aligned normal force is provided between the two frictionally engaged friction locking elements 8, 9 on the one hand and 8, 10 on the other hand.
- the tolerance ring 13 is designed in such a way that it generates a radial spring force here and preferably also.

- the embodiments initially have in common that the middle frictional locking element 8, that is to say the tolerance ring 13, has a plurality of radial elevations 14 in the circumferential direction U.
- the radial elevations 14 are opposite here the side edges 13a, 13b of the tolerance ring 13 and / or opposite here and preferably flat sections 15 of the tolerance ring 13 radially outwards.

- the depressions 16 here, like the elevations 14, have an elongated extension running parallel to the drive axis X.
- Corresponding depressions 16 are also referred to as beads. In principle, however, it is also conceivable to provide a tolerance ring which has no elevations and / or depressions and which is particularly flat, ie completely cylindrical in the circumferential direction.
- the two illustrated and thus preferred embodiments differ in that the radial elevations 14 of the central frictional locking element 8 point radially inwards in one case (FIGS. 3 and 4) and in the other case point radially outwards (FIGS 6).

- the clutch mechanism 7, which is used for the rotationally fixed coupling of the two drive components 11, 12 of the drive train 1, is in each case an overload clutch connected between the drive components 11, 12 in both embodiments.
- the two embodiments differ in the breakaway torques defined between the respective friction surfaces.

- the maximum outer radius is the distance between the center axis of the central frictional engagement element 8 and the point of the frictional engagement element 8 which is outermost radially and which is defined in particular by a section 15 which lies between two radial elevations 14 (FIGS.
- the minimum inner radius is corresponding to the distance between the center axis of the middle frictional engagement element 8 and the radially most inner part of the frictional engagement element 8, in particular through a radially inwardly pointing elevation 14 (FIGS. 3 and 4) or through a section 15 is defined between two radial elevations 14 ( Figures 5 and 6).
