- sliding doors are used more and more. This facilitates access to the motor vehicle and / or gives children, for example, the opportunity to operate large sliding doors for getting in and out.
- the sliding doors are used in vans as well as in passenger cars. Here the sliding doors differ due to their size and weight.
- the sealing pressures to be overcome also play a decisive role in the electrical operation of the sliding doors. This means that various requirements can be placed on a sliding door drive.
- cables are used to actuate, that is, to move or move the doors.
- a sliding door drive has become known in which the cable drums are driven by means of an electric motor and a gearbox and a clutch.
- the rope or winding drums are driven by a reversing drive motor via an interposed gear.
- a rope strand connected to a door arm is wound up on a winding drum and another rope strand connected to the support arm is unwound from a further winding drum.
- the rope or winding drums are stored on one side via a storage in the clutch gear unit.
- DE 198 19 421 A1 discloses a sliding door drive for the sliding door of a motor vehicle, the sliding door being connected to a cable pulling unit with a door arm and the cable pulling unit having at least one cable pull and at least one winding drum for winding and unwinding the cable.
- the winding drum is driven by a reversing drive motor via an interposed gear, with a rope attached to a door arm being wound onto the winding drum and another rope attached to the support arm being unwound from the winding drum when the sliding door is closed.
- the drive motor and the transmission are arranged on the inside of the body, a cable guide being provided for the cable pull.
- the Wickeltrom mel is designed as a one-piece drum. But there is also the possibility of realizing two coaxially mounted winding drums, which are acted upon by means of a spring to maintain the rope tension in opposite winding directions.
- a sliding door drive for a sliding door has become known in which the sliding door can be moved from a closed position to an open position or vice versa.
- the sliding door drive has a reversing motor fastened on the underside of the vehicle floor panel, a speed reducing device and an electromagnetic claw clutch mounted in this speed reducing device.
- a downwardly extending Seiltrom mel below a housing is rotatably mounted on the lower part of the shaft.
- a rotor is connected to the top of the cable drum via a wedge connection in such a way that it can be moved axially to the shaft, but not rotated relative to the cable drum.
- the cable drum is rotatably mounted on a drive shaft, the drive shaft being received in a housing and a housing cover. Disclosed is a bearing on both sides of a drive shaft, the drive The shaft itself, however, in turn forms a bearing point for a ball bearing of the cable drum, so that a structurally complex solution is disclosed.
- the known prior art shows possible solutions for the storage of a cable drum of a sliding door drive, but is overall in need of improvement.
- the forces on the cable drum can vary greatly and / or environmental influences can influence the load on the cable drum.
- the cable drum must be able to provide a torque that is as uniform as possible for actuating the sliding door and, in extreme situations, it should be possible to provide a bearing for the shaft of the cable drums with as little play as possible and thus safe. This is where the invention comes in.
- the object of the invention is to provide an improved sliding drive for a motor vehicle.
- the object of the invention is to provide a sliding door drive for a motor vehicle which ensures play-free mounting of the cable drums, which is structurally simple and which can provide high long-term stability of the sliding door drive.
- a sliding door drive for a motor vehicle with a drive unit comprising a housing, an electric drive, a transmission connected downstream of the drive and a clutch, with at least one being activated by means of the drive unit angle arranged on a shaft drum is drivable, wherein the shaft is mounted at least twice in the housing, in particular at the axial ends of the shaft in the housing.
- the structure of the sliding door drive according to the invention now makes it possible to provide a backlash-free mounting for the cable drums.
- the double bearing of the shaft in the housing makes it possible to precisely guide the cable drums and thus to ensure a continuous drive by means of the cable drums even in extreme situations.
- the shaft is preferably received in the housing at its axial ends.
- Axial ends mean at least the areas of the shaft that lie outside the receptacle or bearing surfaces of the winding shaft or the winding shafts.
- the bearing points for the winding shaft are thus spaced apart on the shaft and on the opposite ends of the cable drum on the shaft.
- the bearing points are preferably at the axial ends or at least on one side at an axial end of the shaft and, as far as structurally possible, at the axial end.
- the sliding door drive has a drive unit and preferably an electric motor with which a corresponding output torque can be introduced into the sliding door drive.
- the electric drive works together with a gearbox to provide the corresponding gear ratios for the sliding door.
- the transmission ratios can of course fluctuate, since different door widths, door weights or door heights can be driven by means of the sliding door drive.
- the gearbox adapts the drive torque and / or the speed of the electric drive to the closing speed.
- the diameter of the cable drum can be varied so that the forces available when moving the sliding door can in turn be influenced.
- the sliding door drive further comprises a coupling so that the drive can be decoupled from the shaft of the winding drum.
- This decoupling of the drive is necessary to enable emergency operation of the sliding door.
- the electric drive has a braking torque that can prevent or at least severely restrict a shifting of the sliding door, in particular in combination with the transmission. So that the sliding door can be moved manually and easily manually in the event of a power failure, for example, the drive chain can be interrupted by means of the coupling and enable the sliding door to be moved manually. Ausense forms of the coupling are known, for example, from the cited prior art.
- a variant embodiment of the invention results when the housing is constructed in several parts, in particular in two or three parts.
- a multi-part structuring of the housing enables easy assembly of the sliding door drive and at the same time there is the possibility of providing bearing points at preferred points on the shaft or winding shaft, which enable well-defined support of the shafts arranged at preferred bearing points.
- the housing is preferably designed in three parts.
- a gearwheel with which the drive motor meshes is rotatably mounted in a lower part of the gearbox.
- the lower part of the gearbox carries the gearbox and the clutch.
- the transmission center part the gearbox is stored on the one hand and at the same time the center part offers a first bearing point for the shaft of the cable drums.
- the housing can be closed by means of a gear cover, whereby a further bearing point for the winding shaft can be provided at the same time through the housing cover.
- the Ge gear cover takes an outer axial end of the shaft and includes a bearing point for the shaft.
- the cable drums or winding drums are received directly on the shaft in a form-fitting and / or force-fitting manner.
- an axially spaced further bearing can be provided for the shaft by means of the housing cover.
- the bearing point in the housing cover is arranged at one axial end of the shaft, so that the most favorable bearing point possible can be made available for absorbing moments from the pull cords of the door drive.
- the shaft is supported by the bearing point in the housing cover at the outer axial end, which means that safe and stable shaft storage can be guaranteed even in extreme situations in which large tensile forces occur in the cables of the sliding door drive.
- a winding shaft is connected to a support arm of a sliding door, so that by means of this first winding drum, for example, the sliding door can be pulled shut.
- the second winding drum has a rope that is connected to the winding drum and other- on the other hand, it is also connected to the support arm of the sliding door, the rope being guided in the body of the motor vehicle in such a way that the sliding door can be pushed open or opened by means of this second rope.
- the ropes of the first and second winding drums thus act in different directions with respect to the sliding door.
- the winding drums can be fastened to the shaft by means of a spring element and in particular by means of a single spring element.
- the winding drums can be mounted on the shaft by means of a tongue and groove connection.
- the shaft is directly connected to the transmission, in particular to a planetary gear carrier of an epicyclic gear, the planetary gear carrier having a receiving means for the shaft.
- the shaft or winding shaft carries the cable drums and is stored in the housing. In the direction of the drive, the shaft can have an axial extension beyond the bearing point and thus come into engagement with the planetary gear carrier of the epicyclic gear.
- the shaft is preferably inserted positively into an opening in the planetary gear carrier.
- the planet carrier itself can preferably be mounted in the housing in the area of the receiving means for the shaft.
- the receptacle has a reinforcing element, in particular a metallic sleeve, so that a reliable transmission of the torque from the gear into the winding shaft is possible.
- the reinforcement element ensures a high level of long-term stability of the sliding door drive.
- components of the sliding door drive such as the winding shaft itself and the planetary gear carrier, can be made of plastic. Ever Depending on the requirements placed on the sliding door drive, the components in the power flow of the sliding door drive can of course also be made of metallic materials such as brass, aluminum or steel.
- the shaft is made of plastic, the shaft being provided with at least one metallic core.
- a plastic shaft offers the advantage of low weight and easy formability, so that a structurally favorable structure and easy assembly is possible. Due to the additional metallic reinforcement of the plastic shaft, the advantages of low weight can be combined with sufficient stability to transmit the required torques.
- the metallic core can extend in regions through the shaft and preferably into a region of the transmission receiving the shaft.
- Another embodiment variant of the invention results when the shaft is mounted in plain bearings in the housing.
- Plain bearings offer a structurally favorable way of achieving high long-term stability and at the same time are extremely compact, and are also advantageously extremely compact and inexpensive.
- the shaft is preferably supported at one axial end in the housing cover by means of a plain bearing and is held in the housing in a rotatable manner in a plain bearing in the middle.
- a sliding bearing for guiding the planetary gear carrier can be arranged in the area of the receiving means for the shaft.
- a sliding door drive 1 is shown in a cross-sectional view.
- the sliding door drive 1 has a three-part housing 2, the housing 2 being divided into a lower housing part 3, a central part 4 and a housing cover 5.
- a drive motor (not shown) can be introduced through an opening 6 of the lower part 3 and can be connected to the housing 2.
- the drive motor engages, for example, with a worm arranged on an output shaft on a worm wheel 7, the worm wheel 7 in this exemplary embodiment being designed with a molded gear 8 as a sun wheel for a downstream Pla designated gear 9.
- the flea wheel 10 of the planetary gearbox 9 the power of the drive motor can be transmitted to a shaft 11.
- the shaft 11 can be inserted into a receiving opening 12 of the float wheel 10 and can be connected to the shaft 11 in a form-fitting and / or force-fitting manner.
- the shaft 11 wiede rum is rotatably received in the housing middle part 4 and in the housing cover 5.
- plain bearings 13, 14 are arranged in the housing cover 5 and in the housing center part 4 in this exemplary embodiment.
- the shaft 11 is consequently guided at its axial ends in the housing 2 so that tilting of the shaft 11 in the sliding door drive 1 can be prevented.
- two rope or winding drums 15, 16 are arranged on the shaft 11.
- the winding drums 15, 16 each serve to accommodate ropes (not shown) for driving a sliding door.
- the ropes of the winding drums 15, 16 are attached to different ends of the sliding door so that the sliding door can be moved in different directions depending on the direction of rotation of the drive motor.
- the shaft 11 is preferably designed as a hollow shaft, but can be designed to be supported with a steel core. This is particularly advantageous when the shaft is made of a plastic. Depending on the embodiment and requirements for the sliding door drive 1, the shaft 11 can be made as a plastic component or made of a metallic material. In this exemplary embodiment, the shaft 11 can be inserted into a receptacle 12 of the ring gear 10, so that the shaft 11 can be driven by means of the ring gear 10. The ring gear 10 is also taken in a sliding bearing 19 in the housing center part 4. In addition, the receptacle 12 can be carried out reinforced with a steel bush 20 ver.
- a safe, tilt-free and stable drive system for the sliding door can be provided.
- the slide bearings 13, 14, 19 for the ring gear 10 and the shaft 11 stabilize the winding drums 15, 16 in the hous se 2, so that the sliding door can be driven with the least possible play and / or drive losses.
- a coupling 21 is also arranged between the worm wheel 7 and the shaft 11. If the clutch 21 is actuated against the force of a spiral spring (not shown), a sliding element of the clutch 21 being displaced in the direction of the arrow P1, the power transmission between the worm wheel 7 and the shaft 11 is interrupted, whereby a manual shifting of the sliding door is possible and / or at least facilitated.
