Definitions
- the invention relates to a drive device, in particular a spindle drive for an adjustable vehicle flap and a telescoping linear guide.
- the invention also relates to a method for subsequent activation of a motorized adjustment of a vehicle flap.
- Drive devices in particular for vehicle flaps that can be adjusted in a driven manner, are known from practice, which are arranged in an articulated manner between a vehicle body and a vehicle flap that is to be adjusted relative to the vehicle body, with such drive devices comprising a drive element, via which, for example, a driven element designed as a spindle rod is rotated in a driven manner in order to thereby to bring about a change in length of the drive device and accordingly to thereby realize a driven adjustment of the vehicle flap.
- This advantageously makes it possible to automatically adjust a vehicle flap between an open and a closed position.
- Such drive devices or the associated possibility of automatic adjustment of a vehicle flap can usually be optionally selected by a customer when purchasing the vehicle, with subsequent provision of this comfort function only being possible by appropriate retrofitting, which must be carried out in a workshop.
- this object is achieved by a drive device or a telescoping linear guide or a method having the features of an independent claim.
- a drive device in particular a spindle drive for a vehicle flap, comprising a housing, a drive element extending along a drive axis, an output element extending along an output axis, and a coupling device arranged between the input element and the output element and having at least one first coupling element for coupling the drive element and the driven element.
- the drive device according to the invention is characterized in that the first coupling element can be displaced by actuation of the drive element from a decoupling position into a coupling position coupling the drive element and the driven element.
- this makes it possible to subsequently activate the drive device to drive the driven element by simply performing a first actuation of the drive element at the time of activation, which then leads to a coupling of the same to the driven element. Subsequently, the vehicle flap can now be opened as usual by actuating the drive element within the drive device between a and closed position are moved by means of the drive device.
- the first coupling element is coupled to the drive element and decoupled from the driven element before the drive element is actuated or in the decoupling position of the coupling device.
- This advantageously ensures that even if the drive device is already installed as standard in the vehicle, a drive for automatically moving or pivoting a vehicle flap is only switched on or activated after the first actuation of the drive element.
- a user of the vehicle can initially only open and close the vehicle flap manually, with no increased resistance occurring due to the drive element or the motor driving the drive element due to the initially present uncoupled state or the initially present uncoupled position of the coupling device. Only the resistance of the output element itself has to be overcome by manually actuating the vehicle flap.
- the first coupling element in a preferred embodiment of the drive device, provision is made for the first coupling element to be displaced axially in a direction parallel to one of the drive axle and the driven axle by actuation of the drive element.
- the first coupling element and the driven element can be spaced apart from one another in the decoupling position if the first coupling element is axially displaced in a direction parallel to the drive axis and the first coupling element and the driven element are not arranged coaxially with one another.
- the first coupling element can be displaced axially in a direction parallel to the output axis by actuating the drive element in the direction of a coupling position.
- the first coupling element and the driven element can be arranged coaxially with one another, so that a coupling to be established between the first coupling element and the driven element by actuating the drive element is possible in a particularly reliable and simple manner.
- the first coupling element and the drive element are in threaded or gear engagement with one another in the decoupling position of the coupling device.
- the drive element is driven and rotatable about the drive axis.
- a particularly secure and reliable coupling of the first coupling element to the drive element in the decoupling position of the coupling device is advantageously ensured, with torque transmission also preferably being made possible between the drive element and the first coupling element, which is required anyway, particularly when the drive device is designed as a spindle drive.
- the first coupling element is displaced axially into the coupling position by rotating the drive element about the drive axis.
- the production of a coupling of the drive element with the driven element requires only the actuation or rotation of the drive element, which is necessary anyway for the motorized adjustment of a vehicle flap, and which is usually driven by a motor designed as an electric motor.
- the first coupling element preferably has a thread which, in the uncoupling position of the coupling device, engages with a mating thread, the first coupling element being displaced into the coupling position by mutual rotation of the thread and the mating thread.
- An axial displacement of the first coupling element relative to the counter-thread can advantageously be brought about by rotating one of the threads and counter-thread.
- the mating thread is arranged in a stationary manner relative to the drive element. This advantageously ensures that a controlled shift of the first Coupling element is possible relative to the drive element. In particular, a reliable and largely low-maintenance configuration of the coupling device is thereby also advantageously implemented.
- the thread is designed as an internal thread and the counter-thread as an external thread.
- the thread is designed as an external thread and the counter-thread as an internal thread.
- the mating thread is arranged on the housing.
- the housing expediently has a cavity which is enclosed by the housing and in which the mating thread is arranged.
- the mating thread is preferably arranged concentrically around the output axis.
- no additional component is required for the mating thread and can already be produced inexpensively during the production of the housing or a housing part belonging to the housing.
- the drive element preferably drives a rotation of the first coupling element about the output axis, the first coupling element being displaced axially into the coupling position by the rotation of the first coupling element about the output axis driven by the drive element.
- the counter-thread is arranged on the drive element.
- the drive element can preferably be rotated about the drive axis, so that when the drive element is actuated or rotated about the drive axis, an axial displacement of the first coupling element can take place.
- the drive element can cost-effectively and reliably both drive the output element in provide the coupling position of the coupling device and also drive the previously required axial displacement of the first coupling element into the coupling position due to the counter-thread provided on the drive element.
- the first coupling element is preferably arranged in a rotationally fixed manner in the housing at least in the decoupling position, so that a relative rotation of the thread and the mating thread is possible.
- the drive element is coupled in a torque-proof manner to the first coupling element and drives a rotation of the coupling element relative to the housing.
- the output element has a coupling section and the first coupling element has a counter-coupling section.

- the coupling section of the output element and the counter-coupling section of the first coupling element are expediently spaced apart axially from one another in the direction of the output axis. Accordingly, there is then no coupling between the driven element and the first coupling element or no coupling between the driven element and the driving element, since the driving element is preferably coupled to the first coupling element. It is also expediently provided that in the coupling position of the coupling device the coupling section of the output element and the counter-coupling section of the first coupling element overlap axially in the direction of the output axis. In the coupling position of the coupling device, there is preferably a rotationally positive connection between the coupling section of the output element and the counter-coupling section of the first coupling element.

- the drive element is designed as a worm shaft, with the first coupling element designed as a worm wheel being in threaded engagement with the worm shaft.
- a rotation of the coupling element designed as a worm wheel can be driven about the output axis, whereby the first coupling element designed as a worm wheel is shifted into the coupling position.
- the coupling device comprises a prestressing means which prestresses the coupling device in the direction of the coupling position. Provision is particularly preferably made for the prestressing means to prestress the first coupling element in the direction of the coupling position. This advantageously ensures that the transition from the decoupling position to the coupling position is achieved reliably and safely.
- the prestressing means is designed as a compression spring, in particular as a set of plate springs or a helical spring, and is arranged between a stop surface inside the housing and the first coupling element.
- the drive device advantageously includes a braking device.
- the braking device is preferably designed as a disk brake with a brake disk set.
- the brake disk set is expediently prestressed by the prestressing means designed as a compression spring in order to provide a braking force.

- a telescoping linear guide for a flap of an automobile in particular designed as a spindle drive, can be delivered which is not driven by a motor in regular operation but follows manual actuation, the manual actuation pulling the telescoping linear guide apart or compressing it.

- the drive device drives the spindle rod, and this, by means of the spindle nut, moves the two telescopic parts in one direction or the other.
- the drive device has a slipping clutch in order to allow an irregular manual operation of the electric linear drive in the event of a fault.
- the resistance to be overcome for an irregular manual actuation is significantly increased compared to a regular manual actuation.
- the drive device is preferably arranged entirely in a drive housing assigned to the linear guide, in particular in a drive housing assigned to the spindle rod.
- the drive device is protected against access from the outside and can only come into active engagement with the linear guide if the external approval for activation is required.
- the drive device is expediently injected into the drive housing. This also advantageously prevents other drives from being externally connected to the linear guide.

- the extension 113d is arranged facing away from the coupling device 120 .
- the second coupling element 124 has an annular base body 124a and a first latching element 124b protruding from the annular base body 124a axially in the direction of the first coupling element 121 and a second latching element 124c arranged radially opposite and protruding axially in the direction of the first coupling element 121.
- the first latching element 124b and the second latching element 124c are each designed as latching hooks with a nose 125 projecting radially inwards.
- the latching hooks can advantageously be inserted with the radially inwardly projecting lug 125 in the first slot-shaped recess 121e or the second slot-shaped recess 121f of the first coupling element 121, so that the first coupling element 121 and the second coupling element 124 are largely non-rotatable with respect to one another.
- the latching hooks 124b, c each have a groove-shaped receptacle 126, which is provided for receiving an annular prestressing means 127.

- the first coupling element 121 and the second coupling element 124 are advantageously fixed in a rotationally fixed manner relative to the coupling housing 128 in the decoupling position of the coupling device 120 .
- FIG. 10 shows an enlarged detailed view from FIG. 8 in the area of the coupling device 120 in the decoupling position.
- the external thread 113a of the drive element 113 and the internal thread 121a of the first coupling element 121 mesh with one another, so that rotation of the drive element 113 about the drive axis X' or the output axis Y' causes the first coupling element 121 to move axially together with the second coupling element 124 can be displaced along the drive axis X' or the output axis Y' in the direction of the coupling position.
- the latching projections 124d of the second coupling element 124 overlap axially with the latching webs 128b protruding from the annular base 128a, so that the second coupling element 124 and with it the first coupling element 121 are fixed in a rotationally fixed manner relative to the coupling housing 128.
- the first coupling element 121 and the second coupling element 124 can advantageously be displaced axially with respect to the coupling housing 128 .
- the coupling housing 128 is fixed to an inner side of the first housing part 109 so that the Coupling housing 128 is arranged both stationary and non-rotatable relative to the first housing part 109.
- first coupling element 121 and the second coupling element 124 cannot rotate about the drive axis X during a first actuation, i.e. rotation of the drive element 113, but can be displaced axially upwards.
- the first latching hook 124b and the second latching hook 124c which are biased inward by the biasing means 127, rest on the external thread 113a of the drive element 113, so that the lugs 125 do not yet protrude into the recesses 113b, c. Since both the first coupling element 121 and the second coupling element 124 are displaced axially upwards by the actuation, i.e. in the present case by rotation of the drive element 113 about the drive axis X, the lugs 125 of the latching hooks 124b, c are also moved in the direction of the groove-shaped recesses 113b, c shifted.
- the internal serration 122a is displaced in the direction of the serration 114a of the output element 114 designed as a spindle rod, so that the internal serration 122a begins to mesh with the serration 114a and a non-rotatable connection is thus established between the first coupling element 121 and the output element 114.
- FIG. 11 shows an enlarged detailed view in the area of the coupling device 120 in the coupling position.
- the first coupling element 121 was shifted upwards axially along the drive axis X′ or the drive axis Y′ due to the mutual thread engagement.
- the second coupling element 124 has also been displaced axially upwards.
- the internal serration 122a was pushed onto the serration 114a of the output element 114, so that a non-rotatable connection between the drive element 114 and the first coupling element 121 consists.
- the axial displacement of the first coupling element 121 has the effect that the latching hooks 124b, c or the lugs 125 are engaged in the groove-shaped recesses 113b, c of the drive element 113 under the pretension of the pretensioning means 127 and thus a non-rotatable connection between the first coupling element 121 and the drive element 113 is produced.
- the latching projections 124d of the second coupling element 124 have been shifted upwards so far that the latching projections 124d no longer overlap axially with the latching webs 128b protruding from the annular base 128a and thus the first coupling element 121 and the second coupling element 124 no longer prevent rotation to the docking housing 128. Accordingly, the first coupling element 121 and the second coupling element 124 rotate together with the drive element 113 about the drive axis X' or drive axis Y', with the first coupling element 121 and the second coupling element 124 forming a non-rotatable connection between the drive element 113 and the spindle rod Provide output element 114.
- the driven element 114 is now rotatably driven by the drive element 113 .
- the telescoping linear guide made up of the first housing part 109 and the second housing part 110, which allows manual actuation, was converted into an electric linear drive by activation, in that the drive device 101 came into operative engagement with the linear guide.
- FIG. 12 shows another exemplary embodiment of a coupling device 220 in the decoupling position in a longitudinal sectional view.
- the output element 214 designed as a spindle rod has a coupling section 214a.
- a serration 214b is arranged in the coupling section 214a, the teeth of which extend longitudinally along the output axis Y of the output element 214.
- the coupling device 220 further includes a first coupling element 221 and a second coupling element 224, wherein the first coupling element 221 is designed as a worm wheel and the second coupling element 224 surrounds radially.
- the first coupling element 221 is with coupled to the second coupling element 224 via a slipping clutch 229 .
- the slipping clutch 229 comprises a tolerance ring which is arranged radially between the first coupling element 221 and the second coupling element 224 . This advantageously enables the first coupling element 221 to rotate relative to the second coupling element 224 when a defined threshold value of a torque acting between the first coupling element 221 and the second coupling element 224 is exceeded, with the first coupling element 221 being axial relative to the second coupling element 224 remains fixed at all times.
- the second coupling element 224 has a counter-coupling section 222 which can be brought into engagement with the coupling section 214a of the output element 214 by axial displacement of the first coupling element 221 and the second coupling element 224 .
- the coupling section 214a and the counter-coupling section 222 are spaced apart axially, so that there is no coupling between the first coupling element 221 or second coupling element 224 and the driven element 214 and a vehicle flap can only be adjusted manually.
- a braking device 250 embodied as a wrap spring brake is arranged on an end of the second coupling element 224 opposite the counter-coupling section 222 .
- the first coupling element 22 designed as a worm wheel with external teeth 221a, has a hollow-cylindrical internal thread section 221b, which is in threaded engagement with a pipe thread 209b provided on a first housing part 209, so that when a drive element 213 in threaded engagement with the external teeth 221a is actuated, which as a Worm shaft is formed, an axial displacement of the first coupling element 221 designed as a worm wheel together with the second coupling element 224 takes place axially along the output axis Y in the direction of the ball bearing 216 or the coupling section 214a of the output element 214.
- the actuation of the drive element 213 in a first direction of rotation causes the first coupling element 221 designed as a worm wheel and the counter-coupling section 222 of the second coupling element 224 to rotate and at the same time be displaced axially in the direction of the coupling section 214a of the output element 214 designed as a spindle rod.
- the coupling section 214a of the output element 214 and the counter-coupling section 222 of the second coupling element 224 overlap from a certain point, with the serrations 214b of the output element 214 then meshing with the internal serrations 222a of the counter-coupling section 222 and thus a non-rotatable connection between the counter-coupling section 222 and the second coupling element 224 and the output element 214 designed as a spindle rod.
- FIG. 13 shows the coupling device 220 from FIG. 12 in the coupling position.
- the first coupling element 221 embodied as a worm wheel has been displaced axially together with the counter-coupling section 222 of the second coupling element 224 in the direction of the ball bearing 216 .
- the coupling section 214a of the output element 214 and the counter-coupling section 222 of the second are superimposed Coupling element 224, so that the internal serration 222a of the counter-coupling section 222 meshes with the serration 214b of the driven element 214 and a coupling between the drive element 213 and the driven element 214 via the first coupling element 221 and the second coupling element 224 is produced.
- the driven element 214 designed as a spindle rod is now rotatably driven in both directions upon further actuation of the drive element 213 designed as a worm shaft, so that a driven pivoting of a vehicle flap can be brought about both in the opening and in the closing direction.
- the pipe thread 209b or the internally threaded section 221b is designed longer, so that advantageously even when the first coupling element 221 or the second Coupling element 224 of the internally threaded portion 221b remains engaged with the pipe thread 209b.
- the exemplary embodiment of a coupling device 220 shown in FIGS. 12 and 13 makes it possible, for example, for a user to only be able to use the drive function temporarily and accordingly to deactivate it again after a certain time has elapsed.
- the vehicle flap to activate the drive function is first in a fully open end position shifted manually.
- the drive element 213 is then driven by a motor in a first direction of rotation, which corresponds to a driven closing movement of the vehicle flap.
- the first coupling element 221 is axially displaced due to the threaded engagement between the pipe thread 209b and the internally threaded section 221b, and a coupling is thus produced between the second coupling element 224, which is coupled to the first coupling element 221 via the slipping clutch 229, and the driven element 214.
- the slipping clutch 229 is adjusted in such a way that it does not slip during normal operation, ie when the vehicle flap is driven between the open and closed position, and the correspondingly required torque for rotating the output element 214 is thus transmitted.
- the drive element 213 is rotated in the first direction until the vehicle flap is completely closed. However, when the vehicle flap is completely closed, the drive element 213 is rotated a little further, so that the first coupling element 221 is also rotated further in relation to the second coupling element 224, with the slipping clutch 229 then slipping.
- the second coupling element 224 is displaced axially a little further in the direction of the ball bearing 216, so that when the vehicle flap is adjusted in a driven manner into the fully open end position, there is still sufficient overlap between the coupling section 222 of the second coupling element 224 and the counter-coupling section 214a of the driven element 214.
- the deactivation is preferably implemented by driving the drive element 213 in the second direction of rotation, which corresponds to an opening movement of the vehicle flap, when the vehicle flap is closed.
- the first coupling element 221 accordingly rotates about the output axis Y and is axially displaced away from the ball bearing 216 .
- the slides Slipping clutch 229 accordingly, since the second coupling element 224 is initially still in engagement with the output element 214.
- the second coupling element 224 is axially displaced together with the first coupling element 221 until the coupling section 222 of the second coupling element 224 no longer overlaps with the counter-coupling section 214a of the output element of the 214 and the coupling between the first coupling element 221 or second coupling element 224 and the Driven element 214 is lifted and the coupling device 220 returns to the decoupling position shown in FIG.
- a braking device of the drive device which is coupled together with the drive element to the driven element by means of the coupling device, the braking device being designed as a multi-disk brake. It goes without saying that the braking device can also be designed as an electromagnetically activatable brake, which can be activated separately.
- the invention was explained above using a number of exemplary embodiments in which a prestressing means is provided which prestresses the first coupling element into the coupling position. It goes without saying that the first coupling element itself can form such a pretensioning means, for example by means of components of the first coupling element which are tensioned at least in the decoupling position and which causes locking or the like with the output element.
- the invention was explained above using several exemplary embodiments in which the first coupling element was axially prestressed in the direction of the coupling position by a prestressing means or in which the first coupling element is secured in the axial direction due to a threaded engagement with the drive element, which ensures that the first coupling element remains in the coupling position.
- other means can also be provided as an alternative or in addition for example, bring about an axial securing of the first coupling element in the coupling position by positive locking.
- latching points can be provided on the first coupling element and an inner surface of the housing, which cause a positive latching of the first coupling element in the coupling position.
- the invention was explained above using a number of exemplary embodiments, in which the first coupling element is shifted into the coupling position after the actuation of the drive element and subsequently remains there.
- the first coupling element can only be reset by external mechanical intervention.
- a restoring device can advantageously be provided which causes the first coupling element to be returned to the uncoupling position, for example a spring system which can be activated from the outside.
